Grand Order


 * For the highest law of magi, see Grand Order.

Quest for the Holy Grail "Grand Order", named after the highest law of magi due to their critical importance, are quests performed by the Chaldea Security Organization in order to reverse the eradication of mankind during the events of Fate/Grand Order.

Singularity
A Singularity (特異点) is an unobservable region that does not exist within Chaldea's recorded history. It's as if a hole has opened up within the timeline, a hole that is separate from the regular temporal axis.

Certain Singularities have their own individual circumstances and mechanisms, however the Goetia-style Singularities involved in the Human Order Incineration Incident follow a general pattern and possess common characteristics. They are sustained by a Goetia-manufactured Holy Grail, which is given to a certain individual within a key historical time period, typically someone who will use it to cause major disruption to history and destabilize the Human Order Foundations. When this is insufficient, a Demon God host may further manipulate individuals and events in order to achieve this end.

The power of the Grails and the circumstances within the Singularities allow for the summoning of Servants and their continued existence in the world, even without a Master. Various Servants are summoned to the era under these conditions without individuals performing a summoning ceremony. The Servants often play a key role in bringing about the disruption to history, as well as resolving it.

The seven primary Singularities involved in the Human Order Incineration Incident have a Human Order Foundation Value associated with them.

The emergence of large Singularities cause disturbances and fluctuations in time which spread out through history like a wave, and can cause other, smaller Singularities to emerge at other points in time.

There are also existences known as Mobile Singularities (移動特異点) which cause a similar distortion, though usually on a smaller scale. These include Sliders such as the female Miyamoto Musashi.

Because of humanity's destruction in 2015, due to the collapse of the Human Order Foundation, Chaldea is forced to travel to Singularities in the past in order to fix the irregularities of history caused by various Holy Grails. The 'Grand Order' is a "name for those who would rise up against human history for the sake of humanity, and combat fate itself."

Lostbelt
As opposed to the Greater History of Man, the history of 'winners' born from correct choices and proper prosperities leading to the "present", the history of 'losers' born from the wrong choices and mistaken prosperity is cut off. Considered "unnecessary" and cut off from becoming even parallel worlds, this history which has hit a dead end is known as a Lostbelt.

Following the attack on Chaldea in 2017, the freezing of the world and the declaration of rebellion against the Greater History of Man, with the threat of a regression into the Age of Gods and the recreation of the world, the survivors are forced to use an experimental method of navigating through imaginary number space, through the Lostbelts, in order to resolve the incident.

After all of the Lostbelts have been established, the Crypters seek to expand the "domain" of their own Lostbelts, which will eventually clash with the other Lostbelts. The one that is built by greater Human Foundation will end up overtaking the weaker one and use it as "nutrients". This process will allegedly continue, until only one Lostbelt is remaining.

Koyanskaya‎ describes the Greater History of Man as "easy mode" and the Lostbelts as "hard mode", though the veracity of her statement has yet to be fully determined.

Similar to the Human Order Foundation Values associated with the Singularities, the Lostbelts have an associated value known as a Lost Depth (異聞深度). Lost Depth is a rank to display how much the Human Order in a Lostbelt has deviated from that of the Greater History of Man.

Procedure
Utilizing Rayshift, the souls of selected subjects are projected into the past, forming Spiriton avatars with the capacity to interfere with historical events. By the efforts of time-travelling agents, anomalous temporal singularities may be eliminated.

The exact procedure of the Grand Order differs depending on the nature of the Singularity, however there are two general goals; the correction or elimination of the distortions resulting from or responsible for the Singularity, and the retrieval or destruction of the Grail supporting the Singularity.

The words of Kirei Kotomine suggest that rayshifting could have been used against the forces of the Lostbelts, with Chaldea being attacked and rendered inoperable in order to eliminate the threat. Unable to rayshift, the survivors were forced to use a method of diving through Imaginary Number Space, using the Shadow Border's Paper Moon system.

Singularities
The initial Singularity detected by Chaldea, believed to be the cause of humanity's future extinction, was located in Fuyuki, Japan in 2004 AD and codenamed Singularity F. The mission to explore and eliminate the Singularity was designated the First Order (ファーストオーダー).

Following the successful elimination of Singularity F and the revelation concerning the incineration of the future, seven even larger Singularities were detected in the past. As Chaldea embarked on the mission of eliminating these Singularities to return history to its rightful course and restore the future, the name 'First Order' was abandoned for 'Grand Order' - a mission named after the highest law of magi, in view of its importance.

During the course of this mission, multiple smaller Singularities emerged and were resolved. When the seven major Singularities were eliminated, an attack on Chaldea led to the final battle against Goetia, the Beast posing as the King of Magic, and the 72 Demon Gods which comprised it, in its temple - a Singularity thought to be the final one, the conclusion of which brought an end to the Human Order Incineration Incident (人理焼却事件).

However, a number of Singularities have emerged since Goetia's defeat, in part due to several Demon Pillars who escaped during the temple's collapse and a few other parties.

Fuyuki: The Contaminated City in Flames
Fuyuki: The Contaminated City in Flames (炎上汚染都市) was the initial Singularity detected by Chaldea, codenamed Singularity F (特異点F) and located in A.D. 2004.

Setting
The Singularity was located in Fuyuki City, Japan in 2004 AD. At this point in history, a Holy Grail War was taking place in the city. Following the Singularity's manifestation, the city was engulfed in flames and all humans vanished, leaving only the Servants. The Holy Grail War was also disrupted, being switched to something else. Subsequently, a corrupted Saber defeated five of the other Servants, with only Caster surviving. The fallen Servants were also corrupted and rose as Shadow Servants. At the same time, monsters appeared in the city.

The core of the Singularity is Fuyuki's Greater Grail, guarded by Saber.

Participants
The participants have varied between different mediums.

Orleans: The Wicked Dragon Hundred Years' War
Orleans: The Wicked Dragon Hundred Years' War (邪竜百年戦争), alternatively The Holy Maiden Savior (救国の聖処女), was the first of the seven primary Singularities in the Human Order Incineration Incident. Located in France, A.D. 1431, it's Humanity Foundation Value was C+.

Setting
The Singularity occurred in France, 1431 AD, shortly after Jeanne d'Arc was burned at the stake. Using the Holy Grail, Gilles de Rais attempted to resurrect Jeanne but was unable to, instead creating a new Jeanne out of the Grail itself, twisted by Gilles's wishes and feelings. Jeanne Alter then summoned five more Servants, giving them all the attribute of Berserker. Jeanne Alter, Gilles de Rais and their forces subsequently began a campaign of revenge against France, killing King Charles VII and many others, including Pierre Cauchon, the bishop who played a key role in Jeanne's death, whom Jeanne Alter personally burned to death.

History
Arriving in the era, Ritsuka Fujimaru and Mash Kyrielight notice a giant ring of light in the sky. Romani Archaman speculates it to be the size of North America, and it may be one reason the future disappeared. He says he‘ll have the Chaldea staff analyze the ring further. The pair soon encounter a French scout brigade, but the soldiers find them suspicious and attack. Defeating the soldiers, Ritsuka and Mash follow a retreating soldier back to his ruined fort. There they learn from him that King Charles VII was killed by Jeanne d’Arc, who was resurrected as the Dragon Witch. Skeleton soldiers then attack the fort, followed by wyverns. But, Jeanne d’Arc herself appears to help slay the wyverns.

Ritsuka, Mash, and Jeanne enter a nearby forest and kill the monsters there to prevent them from attacking the fort. After introducing each other, Jeanne explains to the pair that information about the Holy Grail War she should have as a Servant is missing. Her stats are also ranked down, and she lacks her class skills as Ruler; she feels like a new Heroic Spirit. Mash asks her if she understands the current situation in France. Jeanne answers she does not quite understand it since she was summoned a few hours ago. But, she knows another Jeanne killed Charles VII and conquered Orléans. Romani warns if France is destroyed, then humanity’s progress towards liberty and equality will stagnate in the Middle Ages. Mash tells Jeanne about Chaldea’s mission to undo the Incineration of the Humanity. Jeanne then wonders how her other-self can summon and control so many dragons, which require the highest magecraft to summon. She resolves to defeat the other Jeanne and agrees to help restore the era. Jeanne tells Ritsuka and Mash to minimize their activity in any towns and villages to avoid the other Jeanne’s detection. She says they should gather information tomorrow.

The next day, the group proceed to La Charite to gather information about Orléans, but they discover it to be under attack. Unfortunately, they arrive to find the town already destroyed and its citizens dead. After slaying the monsters there, Romani warns the group of an incoming group of five Servants and implores them to retreat. However, they stay and encounter Jeanne Alter, who reveals she destroyed the town as part of her plan to destroy France. She asks Jeanne why she wants to save the country despite its people betraying her. She continues she no longer hears God’s voice, which she believes to mean that France is no longer blessed by Him. Therefore, she’ll destroy the country in accordance to the Lord’s grief. After calling Jeanne the leftover residue she threw away, Jeanne Alter commands Vlad III and Carmilla to kill her. Mash and Jeanne hold back the two vampires, but they’re soon overwhelmed. Suddenly though, Marie Antoinette appears to help the group fight Jeanne Alter’s Servants. After driving them back, Wolfgang Amadeus Mozart appears and unleashes his Noble Phantasm, Requiem for Death, to hold the enemy back while the group escapes. After they escape, Jeanne Alter orders Saint Martha to pursue them. She then orders the others to continue destroying France while she returns to her palace to summon more Servants.

After escaping and setting up camp in a nearby forest, Marie and Mozart introduce themselves to the group. Mash tells them of the incineration of the human order, which Marie compares to a Holy Grail War in a different form. Mozart notes the abnormality of Servants being summoned without Masters and there being more than the usual seven. Mash explains that the usual rule of seven Servants no longer applies. The group then discuss the matter of facing Vlad, Carmilla, and Chevalier d’Eon, who could be a valuable asset to them. Jeanne warns against the idea though, as she sensed all of Jeanne Alter’s Servants have Mad Enhancement regardless of alignment or background. Romani attributes it to the Holy Grail being used to give them the Berserker class skill. Jeanne then explains her theory why Master-less Servants like her were summoned. She theorizes the cause is the Grail resisting the reversal of causality of it having an owner before the war even started. The group agrees to find other Servants who’d be potential allies before Jeanne Alter does. Later that night, their camp comes under attack by monsters, but the group kill them. Afterwards, they encounter Martha, who explains Jeanne Alter ordered her to observe them, but she ignores that to test their abilities. They defeat her, and she tells them to go to Lyon. There they will find a dragon slayer who can slay Jeanne Alter’s personal dragon.

Heeding Martha’s words, the group go to a nearby town to get information. Because Jeanne’s presence would cause a panic, Marie goes in alone while the others wait outside with Jeanne. She returns to the others and reveals Lyon was destroyed a while ago. The survivors now take refuge in the nearby town. She continues that Lyon once had a protector who was likely the dragon slayer Martha spoke of. But, he was overwhelmed by Jeanne Alter’s Servants when they came to destroy Lyon. Marie also reveals that Gilles de Rais is planning to retake Lyon. After protecting the town from bandits, the group go to the ruins of Lyon to search for the dragon slayer.

As they search through Lyon, the group kill several wyverns. They soon encounter the Phantom of the Opera, who was given control of the town by Jeanne Alter. After defeating Phantom, Romani warns the group to evacuate the town, detecting a dragon and three Servants are heading their way. But they stay to continue their search for the dragon slayer. Romani tells them he is getting a faint Servant reading in the town castle. Ritsuka, Mash, and Jeanne head to the castle while Marie and Mozart stay behind.

Ritsuka, Mash, and Jeanne arrive in the castle to find Siegfried imprisoned. They free him and exit the castle, but they’re confronted by Jeanne Alter and her dragon, Fafnir. Jeanne Alter commands Fafnir to incinerate the group, but Jeanne and Mash barely protect everyone. Siegfried drives off the evil dragon, allowing the group to escape. Escaping from Lyon, they see Charles-Henri Sanson and Lancelot attacking French soldiers with their wyverns. Jeanne goes to protect the soldiers while the others fight with Sanson and Lancelot. Jeanne is confronted by Carmilla while fending off the wyverns, but General Gilles de Rais arrives to attack the wyverns with cannon-fire. Carmilla orders Lancelot to hold off the group while she and Sanson retreat. After defeating Lancelot, the group leave despite Gilles wanting to speak with Jeanne to confirm her identity.

Arriving at an abandoned fort, Siegfried's wounds are healed by Marie but curses on him prevent any further healing. He recalls to the others how he became Lyon's protector, and his defeat by Jeanne Alter's Servants. He says though that one of them hid him in the castle, and Jeanne figures it was Martha who helped him. Jeanne states that they need a high-ranking Servant with Baptism Rites is needed to remove the multiple curses placed on Siegfried. Since she doesn't enough power, the group decide to look for a saint Servant to remove the curses on Siegfried as he needed to slay Fafnir. The group then split up to search; Ritsuka and Mash with Siegfried and Mozart, and Jeanne and Marie together. Before departing Mash gives a communication device to Jeanne, who is later encourage by Marie to reject Jeanne Alter's words.

Ritsuka, Mash, Mozart, and Siegfried travel to Thiers, where they encounter Elizabeth Bathòry and Kiyohime bickering. After the group defends the town from an enemy assault, Elizabeth and Kiyohime attack them after being insulted by Ritsuka. After they're defeated, Ritsuka tells them that they're looking for a saint. Kiyohime tells them that she encountered Georgios. She says that he went west, the same direction that Jeanne and Marie went. Mash then contacts Jeanne, who just made contact with him. She asks for his help in removing Siegfried's curses. Georgios agrees to help once the town under his protection has evacuated. However, the town comes under attack by Jeanne Alter, but Georgios refuses to leave until evacuation is complete. Marie then convinces him and Jeanne to leave while she protects the civilians. After they leave, she is confronted by Sanson and fights him. After defeating him, Marie criticizes his executioner skills since joining Jeanne Alter, and reveals she holds no grudge towards him for executing her. Once Sanson leaves, Marie is confronted by Jeanne Alter, who criticizes her actions due to her end in life. She however remains determined to help the people, saying she has no right to kill them just because of the way she died. Marie then deploys Crystal Palace after asking Jeanne Alter who she is. Thanking Jeanne for being her friend, she goes to fight the Dragon Witch.

Regrouping with the others, Jeanne tells them of Marie's sacrifice. She and Georgios then remove the curses from Siegfried while Kiyohime and Elizabeth join the group. After defending Thiers from another attack, they leave and make camp in a nearby forest to prepare for their assault on Orleans. As they rest and defend their camp, Mash and Jeanne speak with Mozart on separate occasions; he gives the former insight about humans and thanks the latter for being Marie's friend. Meanwhile in Orleans, Sanson is revealed to lost his mind when Marie perished, and d'Eon reports that the group are preparing to attack. Jeanne Alter then orders Gilles de Rais to summon more dragons in preparation for the attack. Back in the camp, Siegfried tells the others their only method of attack is a frontal assault since their location is already known. He asks them to protect him and Ritsuka while he goes to slay Fafnir. Elizabeth and Jeanne resolve to defeat their respective, and Kiyohime says she'll protect Ritsuka while Mozart will use his music to distract the wyverns.

As the group march towards Orleans, they're confronted by Wyverns and later Atalanta. After defeating them, Jeanne confronts Jeanne Alter, who announces she'll have the dragons fight in a new hundred year after France is destroyed. Suddenly though, General Gilles arrives and orders his men to bombard the enemy with artillery. Siegfried then goes to fight Fafnir while Ritsuka and the others fight Vlad and d'Eon. After defeating them, the group is confronted by an insane Sanson, but Mozart's words regarding Marie's rejection return him to normal. After Mozart and the others defeat him, they help Elizabeth defeat Carmilla. The group then help Siegfried in slaying Fafnir, whose death causes the wyverns to panic and prompts Jeanne Alter to retreat with Gilles.

While Siegfried, Mozart, and Geogios stay behind to deal with the wyverns, the others hurry to Orleans' palace. Meanwhile in the palace, Jeanne Alter orders Gilles to protect her while summons another Servant. Arriving in the palace, the group eventually encounter Gilles and fight him. However, they're unable to defeat him, but Kiyohime and Elizabeth implores the others to go ahead while they hold him off. At the throne room, Ritsuka, Mash, and Jeanne confront Jeanne Alter, and Jeanne asks her if she remembers her peaceful days. However, she doesn't remember, prompting Jeanne to vow to defeat her out of pity. After defeating her Shadow Servants, the group fight and defeat Jeanne Alter. As she perishes, Gilles tells her he'll continue their plan to destroy France before she disappears and the Grail appears. This makes Jeanne realize that Jeanne Alter was herself the Grail, having never existed in the Throne of Heroes in the first place. Gilles confirms her realizations, revealing he created Jeanne Alter from his wish to resurrect Jeanne. Accepting that Gilles hates France while she loves it, Jeanne and the others fight him. After he is defeated, she thanks him for helping her and believing in her during life before he disappears. Then, after Ritsuka and Mash retrieve the Grail, the other say their goodbyes to each other before disappearing as the singularity collapses. General Gilles then arrives in the throne room, overjoyed to see Jeanne alive. But, she tells him that she died while he despaired because of it. Jeanne however her farewell to be temporary, feeling they will fight together in a different form and way. She then says her goodbyes to Ritsuka and Mash, feeling they'll meet again, before they return to Chaldea.

Septem: The Eternal Madness Empire
Septem: The Eternal Empire of Madness (永続狂気帝国), alternatively The Emperor of Roses (薔薇の皇帝), was the second of the seven primary Singularities in the Human Order Incineration Incident. Occurring in the Roman Empire of A.D. 0060, it's Humanity Foundation Value was B+.

Setting
The Singularity was located in the Roman Empire in the year 0060 A.D, during the early years of Nero Claudius' reign. Lev Lainur Flauros arrived in the era intending to give the Holy Grail to someone who wished to destroy the era, but he was unable find anyone suitable. Lev then summoned several Servants, including past Roman emperors, who formed the United Roman Empire. This alliance then waged war on the Roman Empire, successfully taking over several of its territories.

At the time of Chaldea's arrival, the United Roman Empire had seized around half of the Roman Empire's territories and had their sights on the capital Rome. Nero's court mage had also fallen at the hands of Caligula. As Romulus didn't wish to destroy Rome, Lev became the court mage of the United Roman Empire in order to manipulate events.

History
Shortly after arriving in the era, Ritsuka Fujimaru and Mash Kyrielight help Nero Claudius and her army defeat an enemy army. After thanking them for their help, Nero asks the pair where they're from, though she is skeptical of their answer of being from the future. Defeating a second wave of enemies, the group is confronted by a Servant, who Nero identifies as her uncle, Caligula. After he retreats along with the enemy army, Nero realizes that he was their general. She then properly introduces herself to Ritsuka and Mash, surprising them with her identity.

Arriving in Rome, Mash tells Nero that they seek the Holy Grail, which she says is the cause of the damage done to Rome. Nero asks to continue their conversation in her palace, but the market is attacked by enemies. After defeating them, Nero speaks with Ritsuka and Mash inside her palace. She reveals an alliance consisting of multiple "emperors" called the United Roman Empire has taken over half of the Roman Empire. She continues that any information about them, including the location of their capital, is scarce as her scouts never return. Nero then reveals Caligula is one of the "emperors" of the United Empire, and further reveals he killed her court mage. Mash and Romani Archaman then realize that one of the "emperors" possesses the Grail causing the Singularity. Nero implores Ritsuka and Mash to help her defeat the United Empire, saying she'll help them obtain the Grail. After they agree to help, Mash asks her if she ever heard the name Lev Lainur, but the name is unfamiliar to her. Mash tells her that he is a mage from their era that Chaldea and humanity, and speculates he may be in the era. Nero says that a powerful mage is in the United Empire, having been seen on the front lines. This prompts Romani to ask her to deploy Ritsuka and Mash as close to the front lines, which she agrees with. Suddenly, a soldier reports the city's eastern gate is under attack by a mid-sized United Empire battalion. Ritsuka and Mash go to defeat the enemy until nightfall.

The next morning, Ritsuka and Mash travel to to set up a summoning circle there using the mountain's leyline. Upon returning Nero has them join her in rendezvousing with her Gaul expeditionary force. Romani tells the pair that, as told by Nero, Gaul is one of the frontlines in the war with the United Empire. So he implores them to join the expeditionary force with the chance Lev may be there. Later the group are attacked by enemy soldiers on their way to expedition camp. . After defeating them, the group arrive at the camp, where they Nero gives the troops a rousing speech for their upcoming victory. Ritsuka and Mash are then greeted by Boudica and Spartacus, both generals of the Gaul expedition. Romani speculates that they are stray Servants like in Orleans before, and finds it encouraging they can find allies in the Singularities. Some time later a soldier reports an enemy scouting party had been discovered, and the enemy is getting away with intel on the expeditionary force. After killing the scouts, Boudica tells Ritsuka and Mash of how she materialized as Servant in the era right after her death. She continues that she thought her summoning to be her chance for revenge against Nero and the Roman People. However, upon seeing Rome being overrun by the United Empire, Boudica fought to save the people of Rome. Revealing that Nero is unaware of her status of being a Servant, she tells the pair she joined Nero because she hates the United Empire more than her. Boudica, with Spartacus, then decide to test her and Ritsuka's abilities to prove they can beat the "emperor" that rules Gaul.

Later, after proving their strength to Boudica, Ritsuka and Mash travel with her and the rest of the expeditionary force to Gaul. She and Spartacus lead the charge against the enemy while the pair goes with Nero to the enemy's base camp. Eventually, the group infiltrate the main enemy camp, where they encounter the current ruler of Gaul. After they defeat him, he reveals himself to be Julius Caesar, and tells them that the Grail is located in the United Empire's capital held by their court mage. Caesar then fights the group again more seriously, but they're able to defeat him again. Before disappearing, he wonders how Nero will react when confronted by the ruler of the United Empire when she arrives at their capital. After being explained the basics of Servants, Nero congratulates Ritsuka and Mash on taking back Gaul from the United Empire.

On their way back, the group overhears rumors from the local populace that an ancient god has appeared on the Mediterranean. Nero decides they should verify the rumors when a soldier reports their rear ranks are being attack by monsters. After killing them, Nero tells the group that they should verify the god's existence before the United Empire does. She then spaces out for bit, which makes the others remember Boudica telling them she has been doing so since the United Empire. They wonder why they're detecting a slight traces of Magical Energy when Nero returns from spacing out like Boudica said before. Then, after defeating hostile remnants of the enemy army, the group travel to the Shaped Isle. There they greeted by the rumored god, the goddess Stheno of the three Gorgon sisters. After slaying some ghosts, Nero asks her to came back with them to Rome to fight the United Empire. Stheno refuses as her combat abilities are sub-par, but she says she'll give the group a special reward that lies in a cave at the end of the coast. Inside the cave though, the group only find and slay the undead and a chimera, Stheno's so called reward. Exiting the cave, they encounter Elizabeth Báthory and Tamamo Cat, who were made to serve as testers for the cave by Stheno. Caligula then appears to attack the group in order to kill Nero on Lev's orders. After he is killed, Stheno tells the group the location of the United Empire's capital.

Continuing their way back to Rome, the group are attacked by an enemy brigade. Killing many enemy soldiers, they are ambushed by more enemies led by Leonidas I. After defeating him, the group finally return to Rome, where they hold a festival to celebrate their victory. Later in her palace, a solider reports to Nero that the special expedition force is under attack by United Empire forces on their way back to Rome. Agreeing to help, Ritsuka and Mash soon arrive to help the special expedition force. After defeating the enemy forces, one of the general introduces herself as Jing Ke and the other as Lu Bu, who had just run off to chase after the enemy. Ritsuka and Mash tell her of Chaldea's mission, and Jing Ke tells them how she and Lu Bu have already killed three enemy "emperors". Later, she scouts out the location of the United Empire's capital as provided by Stheno, and reports back that a city resembling Rome at the specified location. After receiving intel, Nero leads an army commanded by Ritsuka and Mash's allied Servants to attack the enemy capital. Defeating several enemy forces as they make their advance, the army is attacked by Darius III and his undead troops. After defeating him, Ritsuka and Mash are given a message from Nero from a soldier. He reports that their army's rear had been ambushed and Spartacus and Lu Bu have left the battlefield. He continues that after they broke from their main force to chase remaining enemies, another enemy force launched a surprise pincer attack and captured Boudica. Returning to Nero, she decides that they will save Boudica, whose imprisoned in an enemy fort that Jing Ke already found. Despite knowing it may be a trap, they go to the enemy fort.

Arriving at the fortress, the group encounter two enemy Servants, who tell them that Boudica is safely sound asleep thanks to a restraint spell. After Nero demands their name, they introduce themselves as Alexander and Lord El-Melloi II. However, as Alexander speaks with the group, United Empire soldiers launch a pincer attack on them. After the enemy is defeated, Alexander continues to insist he merely wants to talk with Nero as their armies kill each other. He asks her why she is fighting the United Empire instead showing her allegiance to it. He continues that if she chose to be one of the "emperors", she could have avoided many unnecessary conflicts. However, Nero responds with her resolve to continue fighting the United Empire, asking for Ritsuka and Mash's aid to fight Alexander and El-Melloi. After they're defeated, the group rescue Boudica.

Eventually, Ritsuka, Mash, Nero and her army launch their assault on the United Empire's capital. As the army continue the attack, Ritsuka and Mash move towards the palace while discussing of possibly encountering Lev there. A Servant then appears before them near the palace entrance, commending them for their bravery. To her dismay, Nero realizes he is Romulus as asks her to join his empire. A group of enemies then appear to attack her, but Mash defeats them. Afterwards, Boudica talks with Jing Ke how Romulus' charisma has boost enemy morale incredibly to the point where even mere civilians are acting like soldiers. After discussing Nero's loss of confidence, Jing Ke goes to search for a way into the palace while Boudica goes to protect Nero and the soldiers. After Mash leaves after defeating some monsters, Nero talks with Ritsuka about how she wanted to join Romulus when he offered. However, she refused, believing he is mistaken as none of his citizens and soldiers are smiling. When Mash returns, Nero tells them Jing Ke has found a way into the palace. She continues that she and the others will take a small number of elites with them and eliminate Romulus.

Inside the palace, the group are led to the throne room by Jing Ke as they kill monsters. Upon arriving in the throne room, they are greeted by Romulus, who goes on to fight them. After he is defeated, Lev appears before the group, congratulating them on their victory. His appearance confirms his status of the United Empire's court mage as well as the holder of the Grail. Lev reveals his original plan was to give the Grail to Romulus to destroy the era, but the founder of Rome refused. As a result he was forced to manipulate events in order to destroy the era. Lev then incarnates himself into the Demon God Flaurous and fights the group. After being defeated, he uses the Grail to summon Altera and orders her to destroy Rome. However, she kills him and absorbs the Grail into her body. Altera then unleashes her Noble Phantasm, destroying the palace along with Spartacus and Lu Bu. Fortunately, the group has saved by Mash and Boudica's quick use of their Noble Phantasm. Romani reports that Altera is currently moving towards Rome to destroy it. Doubting their chances of victory, Nero reminds the others of Romulus's words of how Rome must continue so the world may stay eternal. Encouraged by her words, the group, joined by Boudica and Jing Ke, get ready to go after Altera. However, they are ambushed by wyverns that were drawn to the Grail connected with Altera. After slaying them, the group eventually catch up to Altera. Nero attempts to talk with her, but Romani warns that she is going out of control by fusing with the Grail. He implores the group to defeated her before she unleashes her Noble Phantasm again. After she is defeated, Altera states she is happy knowing her sword can't destroy everything. After she disappears, Ritsuka and Mash retrieve the Grail. Nero then realizes they will disappear like Altera, Boudica, and Jing Ke. Mash confirms her concerns, and tells her that her memories of fighting the United Empire will vanish when the era is restored. Though saddened by Mash's words, Nero gives her heartfelt thanks to her and Ritsuka before they return to Chaldea.

Okeanos: The Four Sealed Seas of the End
Okeanos: The Four Sealed Seas of the End (封鎖終局四海), alternatively The Navigator of the Storm (嵐の航海者), was the third of the seven primary Singularities in the Human Order Incineration Incident. Located in A.D. 1573, it's Humanity Foundation Value was A.

Setting
The Singularity occurred in 1573 within an endless ocean. Before the arrival of Chaldea, Francis Drake went on a seven day voyage, at the end of which she found Atlantis along with its god, Poseidon. Poseidon attempted to destroy the world but was stopped by Drake, which caused the real Holy Grail held by Poseidon to recognize her as its owner. However, another Holy Grail was placed into the era, and entered into a contention with the real Holy Grail that resulted in the creation of an endless ocean.

Meanwhile, David was the first Servant to be summoned into era, and sometime afterwards the Argonauts, Hector, and Blackbeard were summoned. Medea encountered a magus, who after beating her, instructed her to tell Jason that sacrificing a god to the Ark will make him all-powerful. After being told this, Jason told the other Argonauts to find a god to sacrifice, but Atalanta refused and left. Hector encountered Blackbeard and gave him the Holy Grail, which he used to summon a crew of Servants. Discovering Blackbeard's obsession with Euryale, Hector joined his crew as a double agent until Euryale was found. In the meantime, Atalanta found David and told him what Jason planned to do with the Ark. Learning of this, David decided to wait with Atalanta until allies could arrive in the era.

History
Ritsuka and Mashu arrive in the Singularity on a pirate ship, and subsequently defeat the attacking crew. A crew member then explains that their ship had suddenly appeared in the ocean with compasses and maps becoming utterly useless. The pirate then suggests that they go to a nearby pirate island to replenish their supplies and get clues on the whole situation. After subduing the pirates that attacked them when they came ashore, the pair are led by another pirate to Francis Drake's secret hideout. Mash tries to speak with her, but she refuses to do so unless the pair can best her in combat. After she is defeated, Drake decides to join Ritsuka and Mash alongside her crew, and she throws a feast to celebrate. During the celebration, she explains the bizarre and endless nature of the ocean containing islands of vastly different climates along with winds and currents that make sail very difficult. She continues that she planned to sail out to find a home base for her and her crew tomorrow before Ritsuka and Mash arrived. Then, as Drake offers Ritsuka a drink in friendship, Mash notices that she has the Holy Grail that was previously used to create endless amounts of food and drink. A crew member proceeds to recall how Drake received it by defeating Poseidon in Atalantis at the end of a seven day voyage. Mash realizes Drake was chosen as the Grail's owner by it after she prevented Poseidon from flooding the world and destroying civilization. Later, after defeating some rowdy pirates, Drake gives the Grail to Mash. However, despite that the Singularity remains unresolved, and Romani Archaman realizes that the Grail they received is the real one already existing in the era. He further explains that the endless ocean was created by a contention between the Grail placed to disrupt the era and the real one. As a result Ritsuka and Mash ask for Drake's help in receiving the other Grail to restore the era. After she is given back the Grail, Drake is convinced by Leonardo da Vinci and Romani to help the pair.

The next day, the group sails out but they are attacked by pirates, who are in truth only conceptual beings of the average pirate. Eventually they land on an island where they fight more pirates and Eric Bloodaxe while exploring its jungle. After defeating him, as she continues to search for treasure, Drake finds a viking ship. Inside she finds the ship's sea chart that details the island and the surrounding ones. Returning to the ship, the group proceed to sail to an island in the northwest according to the chart. . After defeating yet more pirates, they soon reach their destination. The group proceed to a leyline and set up summoning circle there. Romani thencontacts them to report his findings on the pirate flag they retrieved early, but communications with Chaldea qucikly cuts off. Concerned for her ship, the Golden Hind, after an earthquake, Drake and the others go back to shore to check on it. A crew member tells her the ship won't move, which Ritsuka and Mash suspect a bounded field around the island as the reason. The group then begin to search for the bounded field's source in order to remove it so they can proceed with sailing. Eventually they find and enter a labyrinth, where they soon encounter and fight Asterios. However, when Drake prepares to finish him, a female Servant steps in and pleads for them to spare his life. Revealing herself as Euryale, she believed the group was attempting to capture her. After Mash tells her of their situation, Eurayle reveals that Asterios set up the bounded field to prevent outside enemies from entering. Agreeing to remove the field, she and Asterios join the group.

After Asterios removes the bounded field, the group leave the island. While sailing, Euryale reveals that a perverted pirate Servant is after her. Eventually, they are confronted by Blackbeard's ship that had been chasing Drake's ship before, then, as the two ships clash, he orders Eric to seize the Grail from Drake while he goes to capture Euryale. Drake's ship is unable to penetrate his ship's armor, though, and Blackbeard boards her ship with Eric, who is revealed to be a Servant of his. Eric goes to capture Euryale, but is defeated by Ritsuka and Mash. After he disappears, Mash blocks an attack from another Servant meant for Ritsuka. The group then retreat after Drake shoots down the ropes attaching the two ships. Unfortunately, Anne Bonny blasts a hole in the ship, but Asterios carriers it despite his injuries.

Carried to a nearby island, the group go to the forest to get wood to repair the ship. While travelling there, Romani tells them that Blackbeard's ship, the Queen Anne's Revenge, is possibly his Noble Phantasm, as it was giving off very strong Magical Energy readings. He also explains that Drake's ship showed the same reading, though he attributes this to the Grail. Romani then realizes Blackbeard's ship truly is his Noble Phantasm, one that strengthens depending on the size of its crew. He further reports that the ship's Magical Energy weakened when Eric was killed. The group resolve to kill the rest of the Servants on Blackbeard's ship to further weaken it. Suddenly, though, they are attacked by wyvern, and after killing them, Mash gets the idea to use their scales to repair the Golden Hind. After being informed by Da Vinci they'll need thirty more wyverns, the group go off to find a nest. While searching for a nest, they hear someone being attacked by wyverns and go off to rescue them. After slaying them, the group find a small and strange bear creature, and a female Servant suddenly angrily appears as well. After she calms down, Ritsuka and Mash tell her and the bear creature about Chaldea's mission and the nature of the Singularity. She then reveals herself to be Artemis and that the bear creature is Orion. The pair then help the group raid a wyvern nest, where they finally get enough scales to repair the ship.

After repairing and equipping the Ship with a ram, the group set sail, with Artemis and Orion joining. As they're about to enter unknown waters, the group discuss how to deal with the Queen Anne's Revenge. Drake suggests ramming them, while Euryale suggests assaulting them with arrows. Artemis suggests someone boarding the ship and causing chaos before ships collide. She reveals that since she was technically summoned as Orion, she can use his power of walking on water as he is Poseidon's son. Eventually, the group confront Blackbeard's ship and execute their strategy. While the ship charges towards his ship, Euryale pelts Blackbeard's crew with her arrows, as Ritsuka and Mash deal with boarders. Artemis boards his ship and fights the crew while Orion sabotages their ammo supply. After his ship's ammo supply is destroyed, Blackbeard attempts to retreat but is rammed by the Golden Hind. Boarding the ship, the group fight Anne Bonny and Mary Read and defeat them. They then fight Blackbeard, and after his defeat, Hector fatally wounds him and steals the Grail from him. After he expresses frustration that Drake disrupted his plans to destroy the era by giving the Grail to an idiot, the group try to catch Hector. However, he boards the Golden Hind and tries to kidnap Euryale, revealing himself to be a traitor in Blackbeard's crew. Asterios tries to save her but is wounded in the battle. After Blackbeard fails to shoot him, Hector boards another ship, taking Euryale with him. With the Grail now gone, Blackbeard's crew disappears, and he himself disappears along with his ship soon after.

As they pursue Hector, the group discuss his plans for Euryale and the Grail when they encounter a storm. Using its tailwind, they eventually catch up to Hector after dealing with a ghost ship. Ritsuka, Mash, and Asterios then board his ship to rescue Euryale. However as they battle Hector and his crew, another ship moves towards their position. Drake fires her ship's cannons at its but they're all deflected. After Hector escapes to the other ship, Artemis recognizes it as the, meaning its captain is Jason. Jason demands the group hand over Euryale to him otherwise he'll send Heracles to attack them. They refuse his demands, so he sends both Medea and Heracles to kill them and steal Euryale. Medea sends waves of Dragon Tooth Warriors to attack the group on their ship, later joining the fight herself later. However, her combat skills are subpar to theirs, so she switches places with Heracles to fight them. The group are unable to defeat him though due to his Noble Phantasm, God Hand. Suddenly though Heracles starts to attack Euryale, whose death would foil Jason's plan, but Asterios tries to protects her. As this is happening, Jason sends Medea to retrieve Eurayle but Drake and Mash protects her. Hector then unleashes Durindana Pilum impaling both Asterios and Heracles. Jason commands Heracles to bring Euryale to him, but Asterios plummets himself and Heracles into the ocean after he thanks the group. The group use this opportunity to retreat from the Argo.

After retreating, the group disccuss the Ark that Jason mentioned earlier. Romani explains the Ark contained the that Moses received from God. When the others wonder about Jason's plans, Romani is confused by Jason's motives as the Ark will punish all who open it. He further explains that the divine punishment laid by the Ark's opening will also destroy the surrounding area. Despite that, though, the group decide to find the Ark before Jason. Later, as they search island after island for the Ark, the group are sent a message by arrow from someone Artemis knows. They then go to meet the letter's sender on the nearby island. After slaying some monsters, the group is asked by the sender if they're friends or foes of Jason, to which Ritsuka answers foes. Pleased by their answer, the sender reveals herself, who Mash recognizes as Atalanta. After Mash introduces her to the others, Atalanta reveals the Ark is a Noble Phantasm and its owner was the first Servant summoned in the Singularity. Another Servant then shows themselves to the group, and Atalanta introduces them as David, the owner of the Ark.

After introducing himself and killing some monsters with the group, David explains to them that his Noble Phantasm, the Ark, is a third-rate one that only kills whomever touches it. He furthers that it is merely summoned with him as he isn't its owner, and states that it'll remain in the world even when he's gone if someone possesses it. David continues that he heard from Atalanta that Jason is after the Ark, so he waited with her until allies would arrive. Atalanta explains she was summoned as part of the Argonauts but she didn't join in Jason's search for the Ark, something he believes will make him a true king. Then, after being asked Eurayle, David explains that sacrificing her, a Divine Spirit, to the Ark would result in the era's destruction. He continues that normally sacrificing a god to the ark would only destroying the surrounding area. However that destruction would increase within the Singularity, destroying one of the foundations of humanity without waiting for it to collapse. After questioning Jason's reasons, the group discuss on how to defeat Heracles. David tells them getting Heracles to touch the Ark would cause it to destroy him. However, the issue that comes with that plan is that even a Berserker would avoid touching such dangerous Noble Phantasm. Afterwards, the group converse on how to lure Heracles away from Medea and Hector. Mash is concerned that they won't be able hold out if all three enemies attack simultaneously, and suggests luring Heracles away from his allies. Orion suggest they hold up somewhere, but Atalanta says no structure on the island would be able to withstand Heracles. Ritsuka then gives their plan on how to defeat Heracles, which everyone agrees with despite the risks.

Following Ritsuka's plan, the allied Archers launch their Noble Phantasms at Jason, who had just arrived at the island. In response Jason orders Hector to protect him and Heracles to kill the Archers. However, Heracles makes killing Eurayle a priority, so she and Ritsuka run from him while their allies protect them on the way. Eventually, they lure him to where the Ark is being held, but he keeps his distance from it. Fortunately, the rest of the group arrive and defeat him in battle. They then push Heracles into the Ark, draining him of Magical Energy unto his death. With Heracles now gone, the group, now joined by Atalanta and David, board the Golden Bind to go after Jason.

As the group chases Jason, the allied Archers fire upon the Argon with the Golden Hind's cannon fire. When they finally catch up with him, Jason uses the Grail to summon a Shadow Servant to attack the group. After it is defeated, Jason orders Hector to attack the group while Medea stays to protect Jason. After he is defeated, Hector tries to kill Eurayle, but she finishes him off with Eye of the Euryale in revenge for Asterios. David then asks Jason who gave him the idea to sacrifice Eurayle to the Ark. He reveals to him that sacrificing her would have destroyed the world. David asks him if either Hector or Medea tempted him with infinite power if he sacrificed a Divine Spirit. Confused by this, Jason asks Medea if David is lying, saying that someone him told that sacrificing a Divine Spirit to the Ark would grant him power and invincibility. Medea answers the world's destruction would technically make him invincible. Angered at being deceived, Jason states how he was going to finally create an ideal nation, a true utopia. Medea, however refutes his intentions, telling him that he'll never an ideal king as his soul is hopelessly twisted. Infuriated by her words, Jason asks how he is unqualified to be king as he built the Argo and gathered a crew of heroes. Medea then uses the Grail to incarnate him into Forneus, saying it is her way of protecting him. As the rest of the group is doubtful of their victory against such a powerful force, Drake inspires them to fight while commanding her crew to hide in the cabins.

After Forneus and Medea are defeated, Jason is returned to normal and asks Medea to heal him. However she is unable to heal him as she herself will soon perish. Medea reveals to him that she possesses memories of her being deceived and betrayed by him despite her adoration. She calls him both cruel and innocent, and states that despite being weak, he attract others to loyally serve him. Medea then tells Jason further that since he betrays too quickly it would be better for him to sink with the world so he won't be betrayed. After he disappears in a rage, she expresses her regret at not being able to protect him from someone. As she disappears, Medea refuses to answer Ritsuka's question who is behind the incineration of humanity as she was defeated by a mage greater than her. She further tells them to prepare themselves against the mage and to gather more allies so they can fight against him. After Medea disappears, Mash retrieves the Grail. As Singularity collapses, Ritsuka and Mash's allied Servants say their goodbyes before disappearing. However before David disappears, Mash asks him if Forneus was truly a Demon God as Romani claims they don't exist. David asks Romani why he doesn't believe Forneus was a Demon God. He answers that it wasn't his image of one, believing such hideous creatures couldn't be summoned by Solomon. Romani then wonders aloud how such a powerful mage as Solomon could command such monsters or even plot the destruction of humanity. David then proceeds to call his son, Solomon, a cruel, vulgar good-for-nothing who would plot humanity's destruction. However, he apologizes for his words as he has little to do with his son, and says Solomon wouldn't honestly consider destroying humanity unless he suffered a major betrayal. After David disappears, Romani is disappointed that they couldn't gain any more information about the Demon Gods and to know that Solomon is involved with the incineration of humanity. Then, after Romani thanks her, Drake is a little disappointed she will lose her memories of Ritsuka and Mash once history is corrected. She then tells Mash that all humans have a dream or wish to want fulfilled, saying all humans perform good and evil deeds to reach their desires even if they don't know it. Drake further tells her that she is better off not knowing her own wish as she'll know it in the end. After expressing her libertarian approach to life, Drake says goodbye to Ritsuka and Mash before they return to Chaldea.

London: The Death World in the City of Demonic Fog
London: The Death-Barrier of the City of Demonic Fog (死界魔霧都市), alternatively The Knight of Londinium (ロンディニウムの騎士), was the fourth of the seven primary Singularities in the Human Order Incineration Incident. Located in London, A.D. 1888, it's Humanity Foundation Value was A-.

Setting
Commanded by Solomon, Makiri Zolgen, Paracelsus von Hohenheim, and Charles Babbage join together to destroy the era regardless of their lamentations towards the incineration of humanity. They proceeded to invade the Clock Tower through its entrance in the British Museum, which was destroyed in the process, and kill all of the mages there to remove any opposition. After his group created a chamber deeper underground, Babbage constructed a massive steam engine dubbed Angrboda, which uses the Holy Grail as its power source. Angrboda then released a magical fog, referred to as Demonic Fog, on to the city's populace over the past three nights. Any person that breathed in the fog would have magical energy drained with various degrees of effectiveness depending on the fog's thickness and their predisposition. While gas masks protected those in the thinnest parts of the fog, though such equipment is rendered useless in the thickest fog as it drains a person's magical energy unto death. An estimated amount of several hundred thousand died as a result of the Demonic Fog cause people to stay indoors. This also left entire areas to be abandoned; the east end be nearly gone by the time of Chaldea's arrival. As well, over the past three days, the streets were soon flooded by a myriad of monstrosities. Helter Skelters, one of the dangerous forces that roam the streets, were created from Babbage's Noble Phantasm, Dimension of Steam. Furthermore, London became isolated from the rest of Britain due to the government being hindered, resulting in a dwindling supply of food and water. In addition due to the fog being powered by the Holy Grail, several Servants began materializing from it.

The Singularity also created distortions that resulted in individuals who should be dead to appear in the era as living beings, such as Henry Jekyll and Frankenstein. The distorted persons will also have their memories distorted to believe they're still alive. Jekyll would go on to form an information network with collaborators from all over London, Victor Frankenstein being a member, in an effort to save London. He soon met Mordred, who had materialized from the fog, and the two formed a partnership, with her doing the field work, to save London.

History
Ritsuka Fujimaru and Mash Kyrielight arrive in the era, they find London to be covered in a thick magical fog that is harmful to organisms that aren't magical. Finding that the city's resident have all locked themselves inside to shelter themselves from the fog, Ritsuka and Mash begin their search for the Holy Grail; believing that its removal will dispel the fog. But before they can begin their search, the pair encounter a girl, who asks them if they're friend or foe since they can breathe in the fog. They don't answer however as they're unsure if she's a Servant or not due to Romani Archaman's instruments being distorted by the fog. Finding them to be non-hostile, the girl decides to leave, telling the pair to move on if they value their lives. Figuring she may know more about the situation than they do, Ritsuka and Mash chase after her. As the pair chase after the girl, they encounter Automatons and Homunculi along the way; discovering that none of them are breaking into any buildings. After destroying a mechanical golem, Mash examines it but is soon ambushed by Jack the Ripper. Finding that Ritsuka and Mash are unhindered by the magical fog and "her own fog", Jack attacks them but they manage to repel her. After Jack escapes, Mash sends Romani pictures of the mechanical golem that she took earlier. As Romani analyzes the pictures, the girl interrupts him when she calls the mechanical golem a Helter Skelter. She reveals that she had been watching Ritsuka and Mash, and decides they're not enemies as they destroyed a Helter Skelter. After Mash asks her for information about London's circumstances, the girl agree to talks and introduces herself as Mordred.

Mordred brings Ritsuka and Mash into a apartment belonging to an acquaintance of hers. The owner introduces himself as Henry Jekyll and details how he and Mordred formed their partnership to combat the fog. After Mash tells him and Mordred about the incineration of humanity, Jekyll tells her and Ritsuka that a lethal fog has descended upon London for the past three nights. He continues that people die, depending on their predisposition, within an hour of inhaling the fog; estimating causalities to be in the hundred thousands. Jekyll further states several areas have been abandoned with the east end being nearly gone. Calling the fog: Demonic Fog, Jekyll details how for the past three days that automatas, homunculi, Helter Skelters, and Jack the Ripper have been roaming the streets committing atrocities. He continues that the Demonic Fog has isolated London from the rest of Britain, and warns the city will fall once food and water depletes. Agreeing to help Ritsuka and Mash, he sends them and Mordred out to protect one of his collaborators, Victor Frankenstein. Defeating several monsters on their way, the group eventually reach Victor's mansion. However, they find someone else there, and Mordred deduces he killed Victor. Admitting that he killed Victor for refusing to join his group's cause, he reveals his True Name to be Mephistopheles and fights the group. After killing Mephistopheles, the group enter the mansion and find a note in its library detailing a plot called Project Demonic Fog. The project's leaders are "P", "B", and "M", who Victor suspected to be Heroic Spirits. Mordred then reveals a girl she found in a coffin in the backroom earlier with a note attached. The note reads the girl is an artificial human created by Victor's grandfather who shared his namesake; the group realize she is Frankenstein's Monster.After Frankenstein reveals she is still alive, the group decide to take her back to Jekyll.

Arriving back at the apartment, the group are told by Jekyll that Frankenstein is not a Heroic Spirit and still alive as she said so before. He then tells them that a large book has been entering buildings and attacking civilians in Soho. Naming it Magical Tome, Jekyll asks the group to deal with the Magical Tome currently terrorizing Soho. Leaving Frankenstein behind, the group defeat some dolls as they travel to Soho. Mordred then fights Ritsuka and Mash in order to train the latter. After their battle is finished, the group receive a transmission from Jekyll saying the victims of the Magical Tome are placed into an unending slumber. He then tells them to go to antique bookshop in Soho where they'll meet another of his informants. Arriving at the bookshop, the group meet with Jekyll's informant, a young boy. He details that nearly half of Soho's residents have been placed in unending slumber by the Magical Tome, and reveals it is on the building's 2nd floor. Deciding it to be too dangerous to fight indoors, the group lure the Magical Tome outside. Their attacks are useless against the book though, which the boy, revealing himself as Hans Christian Andersen attributes to its reality marble. He reveals the tome to be a stray Servant placing people into a dream in search from a Master from whose psyche it can take form from. Andersen names the tome Nursery Rhyme and it materializes as a young girl calling herself "Alice". After defeating her, the group return to Jekyll's apartment now joined by Andersen.

Back at the apartment, the group are told by Jekyll that Jack has returned attacking Scotland Yard. The group rush over to Scotland Yard, killing any monsters along the way, and eventually reach the police station. There they encounter Jack and a Caster-Servant who reveals to be one of leaders of Project Demonic Fog: "P". Confirming Mordred's suspicions that Jack massacred the entire station, "P" reveals he ordered Jack to do it so that he could receive a magically sealed item from the station. He then orders Jack to kill the group, saying that one of them may be her mother. After Jack is killed, "P" teleports back to his compatriots before the group can interrogate him.

Returning to the apartment, the group learn from Andersen that Servants are materializing from the Demonic Fog; such Servants being Andersen, Nursery Rhyme, Mordred, Mephistopheles, and Jack. When Romani says that it's impossible for Servants to appear without the Grail's influence, Andersen theorizes that the fog was created with the power of the Grail. Mordred then goes on patrol with Ritsuka and Mash following her. Defeating several enemy hordes as they patrol the streets, the group eventually come across William Shakespeare who recently materialized from the fog. "P" then appears having planned to procure the newly materialized Servant from the fog for his group. Confirming Romani's suspicions, "P" reveals he and his group have been procuring Servants that materialize from the fog and manipulate them into expanding the fog. "P" reveals his True Name to be Paracelsus von Hohenheim and fights the group. After Paracelsus is killed, the group return to Jekyll's apartment joined by Shakespeare.

After an early morning patrol, the group report to Jekyll about the mass production of Helter Skelters. He suspects it to be Project Demonic Fog increasing their efforts to procure more Servants from the fog after the group killed Paracelsus. After Ritsuka tells Andersen about the singularities, Romani states Project Demonic Fog 's awareness and influence only extends to the streets covered in the Demonic Fog. Then after Mordred says they need to disable the Helter Skelters, Andersen want to get some data from the Clock Tower to prove his theory about the Holy Grail War. Jekyll and Mordred however confirm the Tower's entrance, the British Museum, was destroyed by "Project Demonic Fog" to remove any opposition. Agreeing with Andersen's request, the group leave for the Museum's ruins joined by Jekyll, Andersen, and Shakespeare.

Arriving at the British Museum, the group dig through its rubble to find the underground entrance to the Clock Tower. However, Romani senses magical energy from underground, which turn out to be magic tomes when emerge and attack the group. After destroying the books, Jekyll theorizes they were once grimoires that were brought to life by the Demonic Fog. The group then head underground and confirm the Tower's mages had been killed, and they suspect the culprit is still around. Eventually the group come across a warded door to a library, and Andersen investigates inside with Jekyll while the others guard the door. However,spells on the books prevent Jekyll and Andersen from taking them outside, so the others must defend until they've find the data Andersen is after. As the others continue to defend against hordes of enemies, Jekyll decides to transform into Hyde to fight with them. Andersen eventually finds the data he was looking for, and the group return to Jekyll's apartment after defeat the last of the enemies.

Back at the apartment, Andersen reveals the Servant summoning ritual used in the Holy Grail War was adapted from a ritual that summoned seven against one instead of against each other. While the Holy Grail War was used for selfish desires, the original's purpose was to summon seven of the strongest Heroic Spirits to defeat a powerful enemy. Andersen then suspects that someone predicted the group's coming and placed the needed information about the ritual for them to find. Suddenly though, the apartment is approached by a group of Helter Skelters. After the group drives off the robots, Romani tells them that the Helter Skelters are machines created from a Noble Phantasm, and all of the Helter Skelters are controlled remotely by the Servant that summoned them. This means the machines will disappear if the Servant is killed. As the group ponders about the Servant's location, Frankenstein reveals that she knows where the Servant that controls the Helter Skelters is located. Following Frankenstein's lead, the group go to the Houses of Parliament in Westminster. However, before they're able to go, a large Helter Skelter attacks the group, but Ritsuka and Mash only fight since Mordred is busy protecting Frankenstein. With the destruction of the large Helter Skelter, all other Helter Skelters suddenly shutdown. Mash then takes pictures of the large Helter Skelter as requested by Romani, and she notices the manufacturer's name on it, which was absent from the others, that reads: "Charles Babbage, AD 1888".

The next morning, Jekyll tells the group that Charles Babbage is alive despite Chaldea's historical records saying he should be dead now. Romani attributes this to the distortions created by the Singularity resulting in events changing, and thus the dead still live and don't exist as Heroic Spirits like Jekyll and Frankenstein possibly. Jekyll then reveals that the Helter Skelters that were completely shut downed have all been reactivated. Going outside to destroy the remote controller of the Helter Skelters, the group follow Frankenstein as she once again leads them to the remote controller. But, the group suspect that Frankenstein is misleading them this time, and she reveals her disbelief of Babbage building the Helter Skelters to hurt others. However, Mordred manages to convince her to lead them to Babbage, saying that his actions now contradict her belief in his good nature. Following Frankenstein, the group soon encounter Babbage, who reveals himself to be "B" of the Project Demonic Fog and a Servant that emerged from the Demonic Fog. When Babbage shows lamentation for humanity's incineration Frankenstein speaks to him causing him to begin to surrender. However, he suddenly goes berserk due to "M" using the Grail and attacks the group. After he is defeated, Babbage tells the group to head deep underground, where they'll find the source of Demonic Fog: his Massive Steam Engine, Angrboda, powered by the Holy Grail. After Babbage disappears, the group return Frankenstein to Jekyll's apartment before they head underground.

Traveling deep underground, the group eventually reach the chamber holding Angrboda. There they encounter Makiri Zolgen, the first leader of Project Demonic Fog. Makiri reveals that the Demonic Fog was created to destroy not just London, but all of England, as commanded by his king. He continues that a Heroic Spirit able fully activate the Demonic Fog will soon materialize from the fog. Proclaiming his king's wish to remove world's ugliness, Makiri incarnates himself into Barbatos and attacks the group. After Barbatos is defeated, Makiri attempts to summon a Servant, but Mordred kills him before he could finish the incantation. However, the Demonic Fog served as both the summoning circle and the rest of the incantation, completing the ritual to summon Makiri's intended Servant. The Servant announces himself to be Nikola Tesla, and begins to head towards the surface while the group are unconscious from the massive burst of Magical Energy from his summoning. After the group wakes up, Romani warns them that Tesla is heading to a spot on surface to fully activate the Demonic Fog to spread it across England thus destroying the era. He further explains Makiri's extra line for Madness Enhancement during the summoning made Tesla automatically perform the task he was summoned for. But, before the group can go to stop Tesla they're attacked by several homunculi. After defeating the homuncli, the group encounter Tesla as he walks to surface, and he reveals the activated Demonic Fog absorbs magical energy without limit. Due to the nature of the activated fog, the group are unable to get near Tesla, but the fog disperses when it absorbs the energy from Mordred's Clarent Blood Arthur. Using this moment of opportunity, the group battle Tesla, but the fog soon returns. Before continuing his approach to the surface, Tesla tells the group that he'll head towards where the fog is thickest, which he suspects to be the skies above Buckingham Palace. Stating a lightning strike from him will fully activate the Demonic Fog to destroy the era, Tesla implores the group to kill him before he does so. He soon arrives at the surface to activate the fog, but just as he creates a stairway to sky he encounters Sakata Kintoki and Tamamo-no-Mae.

Meanwhile underground, the group rush back to the surface and see Kintoki and Tamamo had recently fought Tesla. After Kintoki tells them that he dispersed the fog, the group run up Tesla's stairway to finally kill him. After killing Tesla, the group begin to go back underground to remove the Grail from Angrboda. However they're interrupted when Artoria Alter suddenly materializes from the fog, which she absorbs as she materializes. After the group kills Artoria Alter, they return to Angrboda 's chamber to remove the Grail from the engine with Andersen, Shakespeare, Kintoki, and Tamamo joining. However, Romani warns them of a strange distortion similar to a Rayshift in the chamber, and a mysterious figure manifests from the distortion. After appearing he expresses disappointment in Gilles de Rais, Romulus, Jason, and Tesla for their failures. The figure then reveals he is behind the Incineration of Humanity and that his name is Solomon. Accused of being a mere Servant, Solomon explains he manifested under his own power to destroy humanity. He then reveals that the ring of light that Ritsuka and Mash have seen in the skies of the Singularities is his third Noble Phantasm, Ars Almadel Salomonis. Out of his interest in Mash, Solomon decides to summon only four of the Demon Gods and attacks the group. However, after the group manage to kill one of the Demon Gods, Solomon kills Shakespeare, Kintoki, and Tamamo. Mash tells Romani to rayshift them home, but he tells her that Solomon's presence makes that impossible. Stating that he outranks all Servants regardless of their ranks as a Heroic Spirit, Solomon tries to kill Mordred, but his attack is blocked by Andersen. Andersen then explains that Heroic Spirit summoning belongs to the Counter Force, which are summoned as the Grand Servants to protect humanity from a threat born from humanity to destroy it. Solomon confirms that the summoning system used for the Holy Grail War is a degraded version of the one used by the Counter Force to protect humanity. He declares himself to be the Grand Caster and kills Andersen. Solomon then reveals he only came to the Singularity on a whim. Before leaving though, he proclaims that Chaldea isn't a threat to him until they destroy seven Singularities, and calls humans worthless for continuing to live despite their inevitable deaths. Afterwards, the group retrieve the Grail, and return back to the surface. After Mordred says goodbye to them, Ritsuka and Mash return to Chaldea.

E Pluribus Unum: The Grand Battle of Legends in North America
E Pluribus Unum: The Great North American War of the Myths (北米神話大戦), alternatively The White Cloth of Steel (鋼鉄の白衣), was the fifth of the seven primary Singularities in the Human Order Incineration Incident. Located in North America, A.D. 1873, it's Humanity Foundation Value was A+.

Setting
The Singularity was located in North America in year 1873 A.D. Using the power of the Holy Grail, Medb created a twisted version of Cù Chulainn as her wish for him to rule alongside her as her king. Leading an army of warriors that she can endlessly produce, Medb and her Servants began to conquer America to create a new Celtic nation; killing everyone who isn't Celtic. The Americans attempted to repel the Celts, but they were easily overwhelmed by the Celts.

Edison took control of the broken American armies, becoming their President-King. With the aid of Edison's robots, the Americans were able to hold their ground against the Celts, yet they were still unable to completely defeat them. However, his mind affected by the accumulated thoughts of the presidents, Edison became so obsessed with winning the war that he turned into a despot. He had the army force civilians to work in his robot factories.

Due to the actions of both the Celts and Edison, Geronimo formed a resistance against both of them. His resistance eventually got into a skirmish with Cù Chulainn, who easily wiped out the resistance soldiers and gravely injured Rama (a member of the resistance) with Gaé Bolg. By the time Chaldea arrives, the Celts have conquered the eastern half of America while the Americans remain in control the western half.

Ritsuka and Mash arrive in the era in a forest, and they come across a battle with one side having robots resembling that of Charles Babbage. One of the robots mistakes Ritsuka and Mash as enemy reinforcements and attacks them. After defeating the robots, Ritsuka and Mash are attacked by the opposing side when the other retreats. Though they're able to win, Ritsuka is suddenly hit by cannon fire and knocked unconscious. Ritsuka later wakes up in a tent, much to their surprise, being treated by a woman. She prepares to amputate Ritsuka's arm without their consent, but Mash convinces her to stop and uses a magic scroll to heal Ritsuka's wounds. As the woman goes to treat another patient, Mash tells Ritsuka that they're in the rear base of the American Independence Army. She also reveals that the woman is a Servant and her name is Florence Nightingale. Mash tries to ask Nightingale to help her and Ritsuka resolve the Singularity, but Nightingale refuses as she still has patients. However, the camp is suddenly under attack, and Ritsuka and Mash go out to aid the americans. Nightingale decides to join the fight as well, telling Doctor Benjamin Rush to look after her patients. After the enemy is defeated, Diarmuid Ua Duibhne and Fionn mac Cumhaill arrive, and Diarmuid attacks the group. They defeat Diarmuid, but he is healed by Fionn, who joins his subordinate in his fight. After the group defeats them, Nightingale suddenly rushes back to camp as she sensed the wounded soldiers were under attack. However, a Servant arrives with reinforcements, forcing Fionn and Diarmuid's forces to retreat. Later, after reprimanding Rush for his dated medical practices (latest by the era's standards), Nightingale is confronted by a woman with an entourage of mechanized soldiers. The woman warns her to not leave her post or she'll face punishment. Nightingale refuses to listen and almost gets into a fight with the woman if not for Mash's intervention. The woman reveals that America is currently in a war between East and West; East being the Celt and West being the United Western States led by its king. She then properly introduces herself as Helena Blavatsky, and Mash tries to convince her to let Nightingale go with her and Ritsuka to resolve the Singularity. Ignoring Helena's orders to stay put, Nightingale prepares to leave with Ritsuka and Mash. Left with no other choice, Helena sends the mechanized infantry to subdue the group. The group is able to destroy the robots, but Karna appears on Helena's order and attacks the group with Brahmastra.

The group later wake up in a cavern, having been knocked unconscious by the shock-wave created when Mash blocked Brahmastra. Helena explains they're currently being transported, and warns the robots will target Ritsuka if they try to run. She further explains that they going to meet with her king in a effort to convince Ritsuka to join her king. The group eventually reach Denver where the fortress of Helena's king is, which was built when the White House was taken by the Celts. Entering the castle, the group meet Helena's king, Thomas Edison, President-King of the United States. Edison asks Ritsuka to aid him in defeating the Celts, having been informed of their victories in the previous Singularities by someone who angers him. He continues that the Americans were completely outnumbered by the increasing Celts. Edison reveals he took control of the remnants of the American army and was able even the battle with the Celts with his robots. Though he states he lacks enough Servants to combat the Celtic Servants to truly turn the tide. Nightingale asks him if the mechanized infantry is the aim of his new national structure, which he asserts is correct. Edison states that he'll unite the citizens under equal national service regardless of their race or gender. These citizens will eventually become part of the mechanized infantry to combat the Celts. Mass production of the robots will be done by laborers acquired from all across the land who'll have 20-hour work days. The group however disagree with Edison's labor filled vision for the nation as it does not take physical limitations into account. Nightingale then asks Edison how he intends to save the World, which Mash says can be done by recovering the Holy Grail and correcting the era. Edison however reveals he doesn't intend to fix the era, instead he'll use the Grail to create his ideal America operating on a different timeline from the eras. He admits though that will likely result in the destruction of the other eras. The group wholeheartedly disagree his plan as he is ignoring his duty to protect the world as a Heroic Spirit. Nightingale tries to attack Edison, but she is restrained by Karna. Edison then gives Ritsuka three minutes to decide whether or not to join him. Ritsuka decides not to join him, to which Edison sends his robots to subdue the group. Overwhelmed by the sheer number of robots, the group are sent to the underground prison.

In the prison Ritsuka's Magical Energy supply link with their Servants is neutralized by Helena to prevent their escape. Helena asks Ritsuka why they didn't join Edison, and she reveals she knows Edison has become obsessed with self-righteous patriotism upon hearing Ritsuka's answer. Helena states only Edison can stop the Celts despite his obsession, then she leaves after saying someone will rescue the group soon. Later, as the group struggle to escape, a Servant appears before them. Revealing he borrowed another's Noble Phantasm to avoid Karna's detection, the Servant introduces himself as Geronimo. Busting the group out of their cell, Geronimo and others destroy the robot guards and run off. As the group continue their escape, Geronimo reveals he's part of a resistance against Edison and the Celts with three other Servants, and he asks the others to join his group. However as the group near the exit, they are confronted by Karna but they defeat him and flee before he can recover.

Arriving in a deserted town serving as the resistance's hideout, Geronimo asks Nightingale to heal to a Servant member of the resistance. As Nightgale treats him, the group see that his heart has been severely damaged. The Servant introduces himself as Rama, and he reveals Cú Chulain's Gáe Bolg is responsible for his wound. Then, after repelling a Celtic scouting party, Romani Archaman tells the group that Rama cannot healed until the curse from Gáe Bolg is removed. However since fighting Cú Chulainn to destroy his spear is too dangerous a method to remove the curse, the group decide to find a Servant who knew Rama to remove the curse. Rama suggests they find his wife, Sita, who is currently imprisoned somewhere. The group then discuss on how to deal with seemingly endless armies of both Edison and the Celts. Romani states that the Celtic soldiers are continuously born from their queen while Edison's robots are mass produced. He then suggests assassinating Edison and the Celtic queen to stop their armies from growing. Taking Rama with them, the group leave to recruit Servants to aid in the assassination plot.

During their journey, Geronimo detects two Archers, both specializing in guerrilla warfare, being besieged by Celtic soldiers nearby. He then details how the Western American army force citizens to work on the mechanized infantry mass production lines. As he states the War between East and West is currently in a stalemate, Geronimo has the others hide as Celtic scouts come near. Mash prepares to go to cut off the scouts' escape, but Nightingale had already started attacking them. After defeating the scouts, the group move on to the town where the Archers are being attacked. Nightingale (carrying Rama) arrives in the town first to meet the archers, who believe they're the reinforcements Geronimo sent. Arriving in the town, the group eliminate the remaining Celtic soldiers and a Soul Eater that appeared later. The two Archers then introduce themselves as Robin Hood and Billy the Kid to group, and Geronimo introduces them to Ritsuka and Mash. After Mash details the current situation to Robin and Billy, Geronimo suggests the group needs Saber and Lancer to help them. Robin then reveals he met two problematic Servants who Saber and Lancer class earlier. Later, the group arrive at the entrance of the town that one of the Servants Robin met is located. After defeating some unexpectedly weak Celtic soldiers, the group hear a disturbing song that Ritsuka, Mash, and Robin recognize. Entering the town, the group meet with Elizabeth Báthory as she continues her song, which was reason the Celts earlier were so weak. Mash is able convince her to join the group by saying it will help promote her art. Later, passing through a forest to meet the Saber, the group witness Nero Claudius being confronted by Fergus mac Róich who was sent to kill her. Robin uses No Face May King to ambush as Nero reveals his presence. The rest of the group then arrive to fight Fergus and his soldiers. After he is defeated, Fergus tells Rama that Sita is currently being held on Alcatraz Island before disappearing. . Later, at a night after setting up camp, Geronimo informs the group that the Celtic stronghold is the White House. He states the group will split into two; one with Nightingale to rescue Sita while the other will infiltrate the White House and assassinate the Celtic queen. Geronimo decides Ritsuka and Mash will accompany Nightingale and Rama, and Nero convinces Elizabeth to go with them. Taking the others with him, Geronimo is given a communication device by Mash. The next morning, the group split into their respective teams to carry out their missions. .

Ritsuka's group eventually arrive at the coast near Alcatraz, but swimming to the island would be difficult for Ritsuka. Mash borrows a boat from an old man, who warns her Dragonkin on the island. Coming ashore on the island, the group head for the prison as they will wyverns sent by a Servant. Arriving at the prison, the group confront the Servant, who is asked by Nightingale to release Sita. However, he refuses and reveal his True Name is Beowulf, and he sends a dragon to kill the group. After the dragon is slain, Beowulf fight the group but is defeated. Surrending to their victory, he lets the group enter the prison and informs them they'll meet again somewhere else. Inside the prison, the group meet Sita as Rama faints from his wound. After Mash informs her of the circumstances of Rama's wound, Sita tells the group of the curse Rama was afflicted with by 's wife when Rama killed her husband in ambush. This curse keeps her and Rama apart even as Heroic Spirits, and either of them will be summoned as a Rama never to be summoned simultaneously. After the group kills the wyverns, Beowulf comes out to confront them; sending a dragon at the group when Nightingale asks to see a prisoner to cure Rama. However, Sita states she'll disappear when Rama awakens even with the abnormality of the current situation. Nightingale cures Rama of his wound, but Gáe Bolg's curse still persits. Sita then takes the curse into her body, sacrificing herself to dispel it. After Rama wakes up, the group leave to rendezvous with Geronimo's group.

At Washington, Robin returns from scouting, and reports to the others the Celts are preparing for a parade. Geronimo decides the parade is an opportune moment to assassinate the Celtic queen, Medb. Using No Face May King, the group sneak up on Medb and isolate her in Nero's Nuptiae Domus Aurea. However, Cú Chulainn Alter suddenly appears when Medb calls for him and attacks Nero. Confused by Cú Chulainn Alter's strength inside the theater, the group learn from Medb that he was created from her wish on the Grail for Cú Chulainn to be a strong and wicked king who'll stand beside her. The group then go to fight Cú Chulainn Alter when another Servant that Medb called in appears. Cú Chulainn Alter decides he'll fight Nero alone while Medb and the other Servant, Arjuna, fight the others. Geronimo orders Robin to take the communicator and escape. After he escapes, the rest of the group proceed with their battle. Meanwhile, Ritsuka's group fight their way out of Alcatraz, and they are confronted by Fionn and Diarmuid upon exiting. After the group kill them, they receive a transmission from Robin. He informs them that the assassination plan failed, saying the others are now likely dead. Robin then tells the group to meet with him at abandoned United Western States base he is heading for. After receiving the coordinates of Robin's location, the group leave to meet up with him. Meanwhile, as Geronimo's group continue their battle, Geronimo unleashes Tsago Degi Naleya on Arjuna. However, Arjuna easily destroys it with Agni Gandiva, then kills Billy. Medb informs Geronimo she had sent Beowulf, Fionn, and Diarmuid to Alcatraz to kill Ritsuka's group. After Medb states she'll easily destroy Edison's army with the Grail's power, Geronimo informs her that Ritsuka already recovered four Grails to her shock. He then predicts that she will die son, which prompts her to kill him in rage. Medb then orders Arjuna to chase after Robin. Then, After her theater collapses, Nero is finished by Cú Chulainn Alter.

Ritsuka and the others eventually locate Robin to see him being attacked by Celts. After they're defeated, Robin informs the group about what transpired during the failed assassination of Medb. He then details how he was saved from Arjuna and Cú Chulainn Alter's pursuit by a Servant. Afterwards, that same Servant introduces herself to group as Scáthach. Scáthach states she originally intended destroy everything, include the era, until she decided the war needed to be ended by a human when she saw Ritsuka. She refuses Mash's offer to join the group, but says she'll help them. Scáthach then states that not even she can defeat Cú Chulainn Alter, whose power is a result of Medb's wish for Cú Chulainn to be a wicked king rivaling her. She also warns she could destroy the Grail along with Medb but that would greatly delay repairing the era. Romani tells the group to eliminated Medb themselves with Scáthach being a last resort. The group then notice a horde of Celtic forces coming to attack them, and they go to defeat them to protect the camp. As the group continue defeating the Celts, they witness a Servant defeating Shadow Servants summoned by Medb. Impressed by his skills, Scáthach asks for his name, to which he answers Li Shuwen. Li Shuwen challenges Scáthach to a fight, but she refuses unless he can defeat Mash otherwise he must leave. After fighting Mash to standstill, He tells the group they stand a chance against the Celts. Li Shuwen then requests Scáthach to fight him at the end regardless of the world's state. After she accepts his requests, he says Edison seems to possessed by something. Mash invites him into the group, but Li Shuwen refuses yet they can consider him an ally. After he leaves, Nightingale requests to see Edison, believing he is afflicted by something as Li Shuwen said. Ritsuka and the others agree with her request and depart for Denver to confront Edison.

As they travel back west, the group come across a town being attacked by Celts. They prepare to kill them, but Robin instead wants to capture the Celts to use as prisoners. After the group capture a few of the Celts, Ritsuka and Robin take the prisoners to an mechanized infantry robot. Robin states he is Second Lieutenant Anderson Komadori, and says he is transferring prisoners to headquarters. As the prisoners are Celts, the robot is convinced and lets Robin pass. After killing more Celts along with a bicorn, the group proceed to Edison's stronghold. At the stronghold, a robot prevents the group's entry, so they decide to destroy it. Afterwards, Romani's transmission is suddenly hijacked by Edison, who initially believes the group joined the Celts. Inside the stronghold, the group are confronted by Karna. However, as they fight him, Karna is ordered by Edison to return to the throne room. Entering the throne room, the group fight and defeat Edison along with Helena and Karna. However, Edison refuses to give up and prepares to drink an elixir to transform himself, but Karna throws the elixir on the floor. Nightingale tells Edison the Celts are infinite while Edison's army is limited. It then revealed that Edison's tyranny resulted from his mind being affected by accumulated thoughts of the presidents entrusting him with America's future. Nightingale tells Edison he diverted his attention from the world to protect America despite his obligation to protect the world. This makes Edison realize that he strayed from his path, and he becomes worried about having to start over now. However, he is convinced by Helena and Karna to continue as he has always done. Thanking them, Edison apologizes to and thanks Ritsuka, and joins the group.

The group then hold a strategy meeting to devise a way to defeat the Celts. Edison states the Celts will be invading Denver via northern and southern routes. Romani warns if the Celts conquer any more of America then the era will no long withstand its separation from reality and "die". The group eventually decide with a two prong attack with two armies of Servants and robots to attack along the northern and southern routes. One army will hold its ground against the Celts while the other will breakthrough to the White House. The next day Ritsuka decides which Servants will go in which army. The north army will have Elizabeth, Robin, Edison, and Helena. The south army will have Ritsuka, Mash, Karn, Rama, Nightingale, and Scáthach. The north army will hold the Celts long enough for south army to breakthrough to Washington. The north army then depart to the field to await the battle three days from now at dusk. After they're gone, Scáthach decides to hold a practice match against Ritsuka and Mash to test their resolve. After that, Scáthach orders Rama to lead the army as she won't participate in the battle instead monitoring Medb and Cù Chulainn Alter's actions. She tells the group she'll try to hold back Medb and Cù Chulainn Alter as it will mean certain doom for America if they come to the frontline. After Scáthach leaves, Karna asks to stand out in the vanguard in order to get Arjuna's attention. Though uncertain of their victory, the south army start their advance toward Washington.

As the south army arrive in Montgomery, Mash relays a message from Karna stating his vanguard defeated an enemy vanguard yet a few breakthrough. After defeating the stragglers, the south army continue their advance when a scout reports the Celtic army is ahead led by Arjuna. Told that Karna was infomed of this, Rama orders the scout to tell all troop to not engage with Arjuna. At the enemy vanguard, Arjuna orders his troop to attack the south army while he fights Karna. The south army and Celtic army clash while Karna and Arjuna fight. Eventually the south army is able defeat the Celtic army, and Ritsuka and others watch as Karna and Arjuna continue their battle. However, Karna is suddenly struck from behind by Gáe Bolg. Cù Chulainn Alter reveals he killed Scáthach, and then fights the group. Unfortunately he proves too strong for Mash, and he prepares to launch Gáe Bolg to kill her. Fortunately for Mash, Merlin project himself through Fou to distract Cù Chulainn Alter by placing him and Mash in a daydream. Merlin then disappears after staing he and Mash meet again in the future. Karna takes advantage of their distraction and launches Vasavi Shakti at Cù Chulainn Alter with the last of his strength. However, Cù Chulainn Alter survives as the Noble Phantasm wasn't strong enough, and Karna disappears. Cù Chulainn Alter then retreats back to Washington to heal his wounds. The group attempt to march toward Washington, but Arjuna challenges them to a fight. After defeating him, Mash asks Arjuna to join the group yet he declines and leaves. The south army then continue their advance to Washington.

Later at night, the south army continue their advance with Rama ordering them to hurry as the north army is currently engage the main Celtic army. As the south army engage with incoming Celtic forces, the details of the fight between Cù Chulainn Alter and Scáthach are revealed. During their fight, Cù Chulainn Alter and Scáthach both launched Gáe Bolg yet they cancelled each other. Scáthach then activates Gate of Skye to pull Cù Chulainn Alter to pull him into the Land of Shadows, but he activates Curruid Coinchenn to prevent that. He then stabs Scáthach, and she escapes to the Land of Shadows to recover. There she meets Li Shuwen asks him to help the north army until she can recover. Li Shuwen complies with her request, saying he'll be back for their duel. Meanwhile, on the northern front, the north army continue their battle against the main Celtic army. Beowulf then appears and fights Robin and Elizabeth while Helena and Edison fight the Celts. Fortunately for Robin and Elizabeth, Li Shuwen appears and engages in a fistfight with Beowulf. Meanwhile, Ritsuka's group eventually reach Washington, and there they're confronted by Medb. She summons a group consisting of a Shadow Servant, Chimera, and Dragon. After they're defeated, Medb summons a Spriggan, but it too is defeated. Medb then retreats back to the White House, and the group give chase knowing of the potential danger there. Arriving at the White House, the group see the building had been transformed had from its original state. Inside they confront and fight Cù Chulainn Alter and Medb. Medb is mortally wounded by Brahmastra, but she uses the Grail to summon a group of 28 Demon Gods called Clan Calatin to attack the north army. Meanwhile, at the northern front, Edison and the others fight Clan Calatin to no avail. At the White House, Medb gives the Grail to Cù Chulainn Alter before finally disappearing. Cù Chulainn Alter's Magical Energy weakens, which Romani attributes to the self-correction of the era strengthening with Medb now gone. Romani implores the group to defeat Cù Chulainn Alter before the north army is destroyed. As Ritsuka's group fight Cù Chulainn Alter, Edison's group continue to struggle against Clan Calatin. Eventually, Edison attempts to self-destruct himself by overloading his Noble Phantasm to protect the others. But he stopped by the sudden appearance of Nikola Tesla, who arrived to save the era as a way of repentance for his actions in London. Seeing neither of their attack are effective, Tesla and Edison unleash their Noble Phantasms simultaneously to seal Clan Calatin off. Arjuna then appears and sacrifices himself to launch a restricted Pashupata to destroy Clan Calatin. Meanwhile in the White House, Romani reports Clan Calatin's destruction as the group finally defeated Cù Chulainn Alter. However, Cù Chulainn Alter uses the Grail to incarnate himself into Halphas, and Nightingale uses Nightingale Pledge to heal the group. After defeating Halphas, Ritsuka and Mash recover the Grail as everyone say their goodbyes as the Singularity collapses. While Scáthach and Li Shuwen begin their appointed fight, Ritsuka and Mash return to Chaldea.

Camelot: The Sacred Round Table Realm
Camelot: The Sacred Round Table Realm (神聖円卓領域), alternatively The Shining Airgetlám (輝けるアガートラム), was the sixth of the seven primary Singularities in the Human Order Incineration Incident. Located in the, A.D. 1273, it's Humanity Foundation Value was EX.

Setting
The Singularity was located in A.D. 1273, in the Holy Land around. The roots of the Singularity lie in several events. Firstly, someone who should have died midway through the was given a Holy Grail, and using its power, the expeditionary force reached the Holy Land, burning the lands and slaughtering the people living there. However, in their greed, they summoned Ozymandias who subsequently confiscated the Grail and set about building his kingdom there. Having lost the Grail, the expeditionary force lost ground and were eventually cornered by the people of the Holy Land. When they were cornered, a Servant identifying himself as Richard the Lionheart, but displaying different behavior and appearance, appeared and summoned his own crusaders. The crusaders subsequently captured the expeditionary force and occupied the Holy Land.

Secondly, Bedivere did not return Excalibur to the Lady of the Lake, Artoria Pendragon was unable to die when she was fated to after the Battle of Camlann, ending up becoming a wandering ghost. With Rhongomyniad still in hand, she eventually turned into a Divine Spirit, who would come to be known as the Lion King. The Lion King was aware of the incineration of humanity and planned to store a selection of human souls into Rhongomyniad to preserve humanity in some form. After arriving in the Singularity, the Lion King summoned the Knights of the Round Table (with the exceptions of Bedivere and Galahad) and told them of her plan. Aware that some of them wouldn't follow her, she gave them until sunset to decide where they stood. In the subsequent battle, the Knights who decided to follow the Lion King slaughtered their fellow knights who chose to stand against her. The Lion King then bestowed Gifts on the surviving knights, with the exception of Agravain.

The Knights of the Lion King exterminated the crusaders, with the expeditionary force being annihilated along with them. During the battle with the one claiming to be Richard the Lionheart, Gareth sacrificed herself to give the others an opportunity to kill him, unable to bear the guilt of killing her fellow knights any longer. Her brother Gawain was the one who struck them both down. Afterwards, the Lion King and her knights established the Holy City of Camelot in the Holy Land. This occurred about half a year before Chaldea's arrival.

History
Joined by Leonardo da Vinci, Ritsuka Fujimaru and Mash Kyrielight arrive in the era in a desert during a sandstorm. As da Vinci tries to calculate their current location, the group are attacked by enemies. After defeating them, Ritsuka notes the last enemy was a knight when even more enemies including a sphinx appear. The group however are only able to make the sphinx retreat. They then head west towards a source of water, which also has a city according to da Vinci's scans. During their journey, Ritsuka is fatigued by the incredible high mana density in the atmosphere. Da Vinci gives them mana-blocking mask to protect them from the mana-filled atmosphere. However, just as the group near the water source, da Vinci tells Ritsuka and Mash to turn back as she noticed countless sphinxes roaming around the nearby temple. The group prepare to find another route when they're confronted by a group of cloaked people, who believe the group are working for the Sun King. Seeing they're carrying a bound woman, the group decide to fight the cloaked people. One of the cloaked persons' mask breaks during the fight revealing them to be Hundred-Faced Hassan. A cloaked person assumes Mash is from the Holy City, and Hundred-Faced tells the others to retreat as their opponents are Servants. Hundred-Faced tells the group that her current objective is the queen when a cloaked person points out da Vinci took her during the fight. Hundred-Faced demands to know if the group are working for Ozymandias when a group of Medjed appear forcing her and the others to retreat. After they're gone, da Vinci undoes the woman's bounds and wakes her up. The woman announces herself to be Nitocris when she wakes up, and she assumes the group had kidnapped her and fights them. Nitocris struggles against them though due to her own fatigue, but she refuses to give up. She then summons a sphinx as she refuses to listen to the truth of the situation. Assuming the group to be knights of the Holy City, Nitocris sends her sphinx to attack them when a Servant calling himself Lucius appears to help. After the sphinx is slain by Lucius's Airgetlám, Lucius explains to Nitocris the truth of her kidnapping as he had witnessed it. Seeing that she was in error, Nitocris decides to bring the group to Ramesseum Tentyris as a show of gratitude.

As the group travel to Ramesseum Tentyris, Nitocris uses her power to clear the sandstorm, and Lucius takes his leave since he has no business at the temple. After he's gone, Mash notes she felt a strange sensation when near Lucius. Da Vinci then goes on to talk about Airgetlám, Nuada's right arm, that is oddly Lucius' Noble Phantasm. She points out the arm is clearly a replica yet its power is nonetheless extraordinary. Nitocris warns the group she needs to return to the temple before evening otherwise she'll be considered kidnapped. The group introduce themselves to her, and she asks them to protect her until they reach the temple. Nitocris warns that clearing the sandstorm allowed Demonic Beasts from outside to invade the desert when monsters attack. After the monsters are killed, da Vinci ponders if she, Ritsuka, and Mash lured them due to them being from Chaldea. But, she calls her and the others travelling performers so as to reveal their true identity to Nitocris. However, Nitocris becomes suspicious, and asks where the group is from. After revealing she was summoned by Ozymandias, she explains how Ozymandias rose to power quickly after being summoned in the era. She continues others oppose Ozymandias, such as the indigenous Saracens in the mountains. However, when da Vinci mentions Jerusalem as another opponent, Nitocris reveals Jerusalem was destroyed long ago. Finding their lack of knowledge on that subject to be suspicious, Nitocris summons a sphinx as a trial for the group to prove their innocence. After the purposely weakened sphinx retreats, Nitocris leaves as the group passed her trial and continue to the temple.

Arriving at the temple, Mash states she still can't contact Romani Archaman, which da Vinci attributes to the ancient Magical Energy of the desert from the BC era. She continues the desert was transported from another time as the Singularity's space-time is in complete disarray, which was why the group couldn't rayshift to Jerusalem. Da Vinci calls the desert a distortion invading the Singularity, and says there is another location where space-time is distorted. Later, inside the throne room, the group meet with Ozymandias. Wishing to keep the meeting brief due to his fatigue, he reveals his knowledge of Chaldea having already repaired five Singularities so far. He then shows he holds the Holy Grail, but states he isn't allied with Solomon. Ozymandias explains he seized it from the Crusaders after being summoned in the era as the group notice his head coming off. He then orders Nitocris to summon efreets and fights the group. After the battle, Ozymanidas calls the group an enemy as they seek the Grail held by him. He then explains the era collapsed long before Chaldea arrived as the crusades never occurred. Da Vinci accuses him of being the distortion that caused the era's collapse, but he corrects her that the Lion King was responsible for it. After a feast, the group are escorted back to the temple's entrance by Nitocris. The group then continue their journey now in a vehicle built from materials da Vinci took from Ozymandias.

As the group drive across the desert, they are stopped by a blockade of monsters. After the slaying the monsters, the group leave the desert to a burnt wasteland. Da Vinci suspects the era will be incinerated without the use of the Grail when the group are confronted by crazed people looking for food and water. After defeating them, the group decide to leave behind some supplies for the people. One of the people correctly assumes the group is heading towards the Holy City where the Lion King, who eradicated the crusaders, resides. However, the person warns the group to not go near the city walls, telling them to return to the desert if they want to live. Eventually Romani finally contacts the group, who tell him of their situation. He suspects the Lion King is Richard I, but da Vinci reveals the crusaders were eliminated. As Romani is confused about who occupies the Holy City, he detects a nearby Servant, and the group head there. They arrive to see Hassan of Intoxicated Smoke being confronted an Archer Servant as she protects a group of people. Da Vinci warns Ritsuka and Mash to not go near as they'll be killed by Archer if they're noticed. Intoxicated Smoke offers her life to Archer in exchange for him letting the other people go free. However, he refuses and kills her along with all the others are they trying running to the east. As the group watch the massacre, da Vinci warns them to hide until Archer leave as he's stronger than any Servant they encounter thus far. After Archer leaves, the group observe the headless bodies of the people when the vengeful spirit of Intoxicated Smoke attacks them. After being defeated, she thanks the group and asks them to bury her brethren. Complying with her request, the group eventually come across a group of refugees and save them from bandits. A refugee woman tells them that her and the other refugees are heading for the Holy City, as it's the only safe place now. The woman then talks about a monthly ceremony held by the Holy City called the Ritual of Holy Selection where they accept refugees. She continues her and others were heading to the city when her village was burnt down. However, she mentions others think ill of the Holy City and headed for a village in the mountains. After the refugees leave, da Vinci speculates Ozymandias and the Lion King have a nonagression pact while the Saracens are resisting. Romani tells the group to head to the Holy City, which Ozymandias said is the source of the Singularity.

The group eventually at the Holy City by nightfall, and observe thousands of refugees have camped outside. Romani tells them to enter the city to see the Lion King when da Vinci sense a man hiding. The man warns the group to turn back from the city while revealing himself to be thief. After the group discipline him and his cohorts, the man reveals he was merchant who occasionally traded with the crusaders until the Lion King arrived. He continues the knights from the city killed his original group of Merchants yet let him live since he bowed before them. The man then runs away with his group who reveal his name to be Saruhan. Da Vinci tries to ask him for more detail, but he refuses as he agains warns the group to stay away from the city. Disguising themselves with cloaks, the group slip into one of the refugee group further from the main gate. They notice that knights from the city are surrounding the refugees when it suddenly turns into day. A knight emerging from the main gate confesses it is Gift bestowed on him by Lion King so the sun may always bless him. The refugees reveal the knight to be Gawain as the Holy Selection is about to begin. However, da Vinci tells Ritsuka and Mash they need to run as she realizes the truth of the Holy Selection. Gawain thanks the refugees for taking the long journey to the Holy City of Camelot, which he calls the ideal city and only refuge left in the world. He continues the Lion King accepts all into the city regardless of race or religion if they receive his pardon. Then, the Lion King emerges on top of the main gate saying they must choose eternally pure souls as humanity has fallen. Three refugees are then enveloped by a light as they have been selected as pure souls. The Lion King then orders Gawain to collect the selected as he goes to execute the unselected as the Holy Punishment.

As the knights kill the refugees, the group decide to fight the knights to let the refugees escape. After the refugees escape, the defeated knights vanish, and Romani suspects they are constructed humans close to Heroic Spirits. More knights then appear, and Romani warns the group to run. But, they refuse as there are still refugees left who need to escape when someone on the eastern side of the crowd begins fighting the knights. The group use this to their advantage and defeat the knights. A knight prepares to kill a child, but the boy's mother (one of the selected) pleads with the knight to let her son enter the city with her. The knight refuses and kills the mother when she shielded her son. Mash then defeats the knight when he again goes to kill the child. After saving the child, Romani orders the group to escape through the west when Gawain stops them. Gawain's appearance makes Romani realize the Lion King is King Arthur who with the Knights of the Round Table eliminated the crusaders and built Camelot on the Holy Land. He continues the Spirit Origin observed from the Lion King is far beyond King Arthur in Chadlea's data, and goes outside of being a Servant. Gawain recognize the group as defenders of humanity and those from the prophecy who would come and disrupt the Lion King's plan. As Gawain prepares to fight, Romani implores the group to run due to Gawain's Numeral of the Saint Skill. However, the group are forced to fight him, but they're unable to defeat him even with he holding back. Da Vinci asks Ritsuka to buy some time as she sees Mash is struggling against Gawain outside reasons of combat. Ritsuka asks Gawain what the Holy Selection, to which he answers the Lion King and his fellow knights seeks the completion of a utopia. He continues pure humans are selected for that purpose while those not chosen are purged. Gawain then attacks Mash while reprimanding for not hating him as the commander of the knights who executed the refugees as she did with the other knights. Fortunately for Mash, Lucius appears and block Gawain's attack as he rebukes him for denouncing Mash's beliefs. Lucius uses Airgetlám to disable to disable Gawain's gift as the latter recognizes the former as Bedievere. In the insuing fight, Bedivere brushes Excalibur Galatine aside to Gawain's shock. However, Bedivere's arm begins burning inside and out, but he tells the group to ignore it and escape. Da Vinci states she defeated the enemies at their rear while the others were fighting Gawain. Mash carries Bedivere while Ritsuka takes the child Mash saved earlier. Da Vinci then throws a flashbang to disorient Gawain as she and the others escape.

As the group escape, Romani reports the refugees are escaping while being pursued by enforcement knights. The group go to fight the knights since Gawain retreated as it is night once again. Meanwhile, in the throne room of Camelot, Gawain is blasted out of the city's walls by Rhongomyniad as punishment for his failure. However, the Lion King pardons him since he survived as confirmed by Mordred. The Lion King orders Mordred to return outside the city as she only allowed in the city during the day. After Mordred leaves, Agravain prepares to issue orders for Mordred to pursue the refugees. But, the Lion King calls the order unnecessary as the refugees will eventually die in the wasteland. She states that they will do battle with Ozymandias when Lancelot returns. After the Lion King leaves, Agravain orders Tristan to contact Lancelot and tell him to pursue and eliminate Ritsuka's group. Back with the group, they are thanked by a refugee man for saving him and others. However, he and the other refugees have trust issues, so Bedivere asks the man guide the group to the mountain village for shelter. The man agrees with the proposal, and Bedivere tells him the group will protect the refugees until they reach the mountains. He further asks the man to act as between the group and the Saracens to avoid fighting, which the man again agrees with. As the man speaks with the other refugees, the group take an hour break before heading north to the mountains. While da Vinci treats the refugees, Bedivere apologizes for his false name earlier since he couldn't trust the others yet. He confirms Romani's suspisions that he originally intended to seek into Camelot while in disguise yet choose to help Ritsuka and the others. His intentions were to enter Camelot to ask King Artur why he resorted to tyranny. Romani states the Singularity was originally intended to have an endless crusade to destroy the era. He continues Chaldea would have done battle with the crusaders turned Demon God if they arrived before the Lion King did. The Lion King constructed Camelot and took control of the era, which distorted the Singularity even further. Romani realizes the Lion King only seeks to enrich Camelot while ignoring the era being incinerated. Bedivere then reveals he went to sent to the era by Merlin, who told him of Chaldea's mission. He further reveals the Knights of the Round Table conquered the Holy Land and constructed Camelot when he arrived. Seeing the Lion King is the era's distortion, the group decide to help Bedivere as they depart.

Later, as da Vinci and Mash play with Rushd (the child Mash saved), Bedivere reveals his Airgetlám is a replica of the real one provided by Merlin to compensate for his one arm. He continues to he can't handle the arm for long periods otherwise he'll be burned. Da Vinci then states the Knights of the Round Table were given blessings by the Lion King called Gifts. She continues only Bedivere can counter the Knights' Gifts, but that method is reckless since he is injured with every use of Airgetlám. She decides she needs a workshop to analyze Gift when monsters attack. After slaying the monsters, the group continue to the hidden mountain village when Enforcement Knights arrive to kill the refugees. After the first wave is defeated, Lancelot orders the third wave to surround the refugees during combat and capture the group as the second wave attacks. Bedivere attempts to fight the numerous, but da Vinci turns her vehicle into a bomb and drives it into the knights. Her sacrifice allows the group to escape to the mountains as the third wave of knights gives chase. After the group escapes, Lancelot orders his knights to search the mountains for the group. Continuing their journey, the group talk about the lack of food when monsters attack. After the monsters are slain, Bedivere cooks them to provide everyone with food. After eating, the group see many indentations across the land that resulted from the Lion King's Judgement striking there. Romani suspects the Judgement is a Noble Phantasm of King Arthur, and further speculates it as to why the mana in the atmosphere is so dense. The refugees initially had no choice but to go to Camelot due to the dangers of the wastelands and desert, and the lack of food in the mountains. Seeing that King Arthur and the Knights of the Round have fallen, Bedivere decides the Lion King cannot be allowed to exist.

Nearing the hidden eastern mountain village, the group is confronted by Assassin who considers them to be intruders. However, the refugee guide explains the group protected him and the other refugees during the journey. He then pleads to let them take shelter in the village as they are being pursued by the Knights of the Round. Assassin lets the refugees take shelter, but he attacks the group as he is wary of them being allied with Camelot. After being defeated, he reveals himself to be Hassan of the Cursed Arm, and tries to fight again despite his injuries. However, Arash arrives to stop him as he repeats Cursed Arm's words of gratitude when he heard the refugees were saved. Arash convinces him to accept the group despite Bedivere being with them. Cursed Arm then grants the group passage into the village, and tells Arash to show them around while he prepares a place for the refugees. Inside the village, Arash learns of the group's circumstances. Bedivere then express his intent to return Camelot alone, but Arash tells him to rest as Romani states his Spirit Origin looks terrible. Arash then asks the group to help him defeat the bandits and monster surrounding the mountain, believing it'll help gain the villager's trust. After returning to the village at night, Romani suspects the group lost the Knights since they've been staying in the village for a week. Mash states while fighting the knights is inevitable, the group lacks the strength to do so. She also says the group cannot also leave the village in such poor condition. Bedivere then appears and asks to speak with Ritsuka and Mash alone somewhere. Mash tells him she is a Demi-Servant, a human fused with a Heroic Spirit whose name is unknown to her. Bedivere then reveals the Heroic Spirit fused with Mash is a Knight of the Round who was the strongest, wisest, and bravest of them all. He further states the knight chose a path of wisdom and spirituality instead of one of strength and martial prowess. However, he refuses to reveal the knight's name to Mash, believing she should discover on her own. Mash then realizes her agony at seeing Gawain and Camelot's walls was due to the knight expressing their disbelief that it's the work of King Arthur. Bedivere agrees the actions of the Lion King are not the same as the original King Arthur. He then again express his intent to defeat the Lion King, the reason he came to the era. Believing Ritsuka and Mash have no reason to fight the Lion King, he states he'll try to ally with Cursed Arm to fight the Lion King. However, Ritsuka and Mash say they will fight the Lion King to make amends to all those lost. Pleased with their answer, Bedivere tells them he'll try tommorrow to convince Curse Arm to fight with him.

The next day, Ritsuka asks Cursed Arm to help them fight the Lion King. Cursed Arm reveals he and the others were waiting for an opportunity to launch a counterattack against the Lion King. He further reveals the other hidden villages, each protected by a Hassan-i-Sabbah, are gathering forces. Stating they need more manpower, he decides to test the group to see if they can be trusted given Mash and Bedivere's identities. Cursed Arm asks Arash to join him, and together they fight the group. After being defeated, Cursed Arm accepts the group as allies. He tells them he'll take them the headquarters of the Hassans, stating the other Hassans should arrive there in a few days. He then reveals Hassans he gathered as allies were killed by the Knights of Round; Lancelot killed Hassan of the Trembling Pipe and Gawain killed Hassan of the Peeling Shadows. Learning of Intoxicated Smoke's death, Cursed Arm is suddenly warned of an attack on the western village by Mordred.

Given it would take two days to travel to the western village, Arash shoots himself and the others there. After slaying monsters upon landing, the group ambush and defeat several of Mordred's knights. Mordred then confronts them as Ritsuka, Mash, and Romani realize she isn't the same Mordred from London. Mordred then reveals her Gift to be Rampage, which allows her to launch her Noble Phantasm until her soul burns out. She becomes shocked to see Bedivere with the group as he reveals his intentions. While Bedivere fights Mordred, the others fight the Enforcement Knights. Enraged she is losing despite her Gift, Mordred removes her helmet as her armor rejects her Gift. She then prepares to launch Clarent Blood Arthur, but Arash shoots her joints to stop her. Mordred then retreats given her unit was eliminated, saying she'll fight the group in Camelot. The village is successfully protected, but Bedivere passes out from the strain.

Bedivere dreams of his past when King Arthur visited him alone in a tower, stating some villages must be dismantle to deal with the upcoming winter. Arthur saw that as unfortunate given they just drove away the Picts. Bedivere believed Britain will never perish nor suffer as long as King Arthur lives. Arthur corrected him rgat Britain still suffers despite Camelot and its surroundings flourishing. He continued that Camelot cannot restore the lifestyles of those whose villages were lost even if it accommodate them. He believed future prosperity is brought about by hard work, living fulfilling lives, and raising a family. Arthur said there is no future for those merely who're sheltered as Bedivere recalled the king's grim disposition towards Britain's dark future. Bedivere then asked why he was made a Knight of the Round despite being inferior to the others. Arthur called him a fool as he too is inferior to others. He continued that bonds are not measured by strength or weakness alone, stating the Knights of the Round each serve different roles. He then confessed to Bedivere that while the Saxons are their enemies they are not evil. Arthur further explained that the Saxons' search for land to live on is inherently good, believing they'll serve a role in Britain as long as that's true. He continued that conflict will arise as long as they're humans, stating it is born from benefit and detriment. Arthur then stated creating the Knights of the Round from strength alone would only invite evil during this conflict-filled era. The Knights took their oath to not kill their enemies but to fight for the future of their brethren. Arthur claimed Camelot was built from man's desire to built a utopia with their own power albeit barely. He then said for that reason they need compassionate knights like Bedivere to pick up on the details of people's lives that he and Gawain would overlook. Bedivere remembers learning of Arthur's hopelessness from Merlin. He confessed his joy of living Camelot to Arthur who smiled at Bedivere's joy. Remembering the king smiled for others' joy inside of his own, Bedivere begs for forgiveness for fighting against Arthur now.

Meanwhile, Arash expresses concern for Bedivere's physical and mental state as he was begging for his king to forgive him in his sleep. Mash admits she feels a sense of guilt towards fight King Arthur due to the knight fused with her. She and Romani talk of Bedivere returning Excalibur to the lake in Arthur's final momments, and Arthur's future return from Avalon to protect and lead Britain. Cursed Arm returns from checking on the village, and thanks the group for their aid. Hundred-Faced then appears and thanks the group for helping as well. She introduces herself as the village's leader when she recalls meeting the group in the desert before. She refuses to help the group due to their previous encounter and Bedivere's presence. Cursed Arm then asks the group to help him and Hundred-Faced save a Hassan who had been captured by a Knight of the Round. Hundred-Faced states the fort Hassan is held in is nearly impenetrable, though none who tried ever returned. She then tells the group to prepare a hostage in exchange for the captured Hassan; Mash suggests using Bedivere. Hundred-Faced agrees, and the group depart for the fort while Arash stays behind to protect the village. Defeating some bandits, the group eventually run into a Servant screaming for help as she's attacked by monsters. After rescuing her, the Servant complains about her current situation when a dragon appears but is slain. The Servant then introduces herself as Xuanzang Sanzang who was summoned in the Singularity about half a year ago. She reveals she lived in Camelot as an honored guest for two months. She admits left despite it being a prosperous place as she had other places to see. Sanzang then thanks the group for their help and joins them. She also reveals she met a Servant while ago who she took as a disciple but he got capture in front of a fort belong to Camelot. She continues she tried to return and save him, but instead she got lost. The group decide to help her given that they're going to same place.

Arriving at the fort, Romani confirms two Servants in its dungeon. Mash suggests jumping the gate when the watchman is distracted. But Sanzang senses the fort is high alert due to the group's earlier encounter with Mordred as Hundred-Faced suspects. Cursed Arm suggests they wait for an opportunity to enter when soldiers come out of the fort while the group hides. The soldiers reveal Agravain is coming to secretly visit the fort, speculating he is there to personally kill a bowman they captured earlier. They speculate Agravain is there to torture a Hassan they also captured earlier for information since the other tortures gave up. Given the circumstances, the group decide to rescue Hassan and Sanzang's disciple before Agravain arrives. Sensing incoming knights, Cursed Arm suggests the group to split into two parties; one to rescue the Servants another to ambush Agravain as a diversion. Romani states the group will need twenty people to make the fort mobilize. Hundred Faced states she'll create the diversion alone as she showcases Zabaniya: Delusional Illusion. Agreeing with this, the others sneak into the dungeon. After slaying ghosts, the group continue to explore the dungeon as they discuss Agravain's role in legend. Then, thanks to Fou, Mash finds a hidden passageway with cells with one guarded with a Servant inside. After the guard is defeated, Sanzang's disciple exits his cell and introduces himself as Tawara Touta. He confesses he was looking for Sanzang after she went to fight some knights in the fort, but was captured by Lancelot. Touta then reveals Hassan's location, so the group rush to rescue her. As the group rush to Hassan, Romani reports Hundred Faced is currently engaged in combat with Agravain's forces. Eventually the group find Hassan of Serenity chained to wall of the torture chamber with Agravain's Iron Punishment. Given the chains adverse effect on Servants, Ritsuka undoes Serenity's bonds. After rescuing her, the group is confronted by Agravain who sends his Enforcement Knights at them. As they continue defeating knights, Agravain keeps sending more, so Romani implores them to escape. However Cursed Arm sees Agravain has cut off their escape with his knights. Agravain then asks Sanzang what she thought of living in Camelot as he offers her to join the Round Table to replace Gareth. She confesses Camelot is wondeful but disagrees with the matter of the Holy Selection and killing those not chosen, which Mash agrees with. Agravain sees killing the unchosen as an act of mercy and to protect Camelot. He further states Camelot would cease fighting the Saracens if they gave up on the Holy Land. Sangzang then reveals she saw the world's end when she crossed the desert. She also asks Agravain how the Lion King lost her human heart, and if she is still a Heroic Spirit. He refuses to answer and sends his special brand of Enforcement Knights modeled after the enraged Lancelot. After defeating the knights, Mash reveals Agravain doesn't have a Gift as he didn't want one. Romani tells the group to kill Agrvain, but Agravain reveals his death will not stop his knights. He begins to state the Holy Lance is entering its final state, but he quickly retreats as he sensed Serenity activated Zabaniya: Delusional Poison Body. The poison knocks the knights giving the group the chance to escape.

Exiting the fort, the group are told by Hundred Faced that Agravain return to Camelot on horseback. She lets them deal with the remaining soldiers while she steals some horses. After defeating the soldiers, the group return to the village on horseback. Back at the village, everyone holds a feast at night thanks Touta using his Noble Phantasm, Bale of Inexhaustibility to produce the food. During it Cursed Arm tells Mash of how he replaced his right arm with the demo Shaytan's arm in a desperate bid to become the next Hassan. He senses bandits and monsters have been attracted by the food, and he goes with Ritsuka and Mash to defeat them. Later the trio go rest for the night as they'll be discussing their next move tomorrow morning. Meanwhile, back at the fort, Tristan is given a casualty report, and begins killing the remaining soldiers for their failure. However he stops when one of the soldiers say they'll organize a search party to find and eradicate the group along with the mountain villages. The next morning, at the village, Hundred Face and Serenity fight Ritsuka and the others. After that, Hundred Faced states they launch full-scale attack on Camelot with a united force of those who lost their families and stake in the Holy Land, and asks Ritsuka to help them. She continues half of the villagers have agreed to join the the attack. They have 7000 soldiers at hand while Camelot has less than 10,000 soldiers who can individually three soldiers of theirs. She further states the soldiers will be doomed if the Knights of the Round, and warns they cannot any longer as resources are quickly depleting. Touta believes they can defeat the Knights of the Round since they outnumber the knights in Servant count. Arash however warns him of each knight (minus Agravain) possessing a Gift, doubting three of their group could defeat one knight. Hundred Face says they'll need to gather more soldiers, and says they'll need to deal with the Knights of the Round one by one. She continues the assault on Camelot will failure as long as Gawain is at the front gate. A night attack is out of the question due Gawain's Gift. Bedivere says they'll need Lancelot just match Gawain's strength in daylight. Sanzang then suggests they get Lancelot to join their side, but Touta put that idea down. Romani is against attacking Camelot for the time being, and warns they still need to deal with Ozymandias. Serenity then suggests going to the Shrine of Azrael to ask for help from the First Hassan]], whose location was why she was tortured, despite the taboo of asking for his help. Bedivere reveals he knows of the First Hassan as he told to visit him first in his fight against the Lion King. Cursed Arm agrees with the idea, and tells others to return to the eastern village. There he will show them the secrets of the Hassan sect.

As the group travel back to the eastern village, Hundred Faced parts way with them to gather more troop. Two days later they return to the village, and feed the village with Touta's Noble Phantasm. The group discuss recruiting the First Hassan, though Romani doubts he can defeat the Knights of the Round with Gifts and the Lion King. Bedivere assures though that the First Hassan is a special Servant whose blade makes all Servants be killed by "their own fate". With Arash stay behind to protect the village, the group begin their journey to Shrine of Azrael. While climbing cliffs to reach the shrine, they are attacked by monsters and insane humans. After defeating them, the group head for a pilgrimage lodge to rest before continuing to the shrine at dawn. Later at night while the others are sleeping, Sanzang tels Mash her disinterest in fighting the Lion King and Ozymandias whose nation is a strict yet peaceful dictaroship in her opinion. She considers both kings to be the same in their bid to protect their own people. She understands their sense of justice as well as their wrongdoings, which makes it difficult for her to make a stand. Sanzang then decides she'll join Chaldea after the era is restored.

The next day, the group reach the Shrine, but it's guarded by ghosts placed there by the First Hassan. After defeating the ghosts, they enter the shrine where the First Hassan greets them while completely hiding his presence. He tells them he will join in their fight against the Lion King, but warns entering his shrine is punishable by death. However, Hassan says he'll forgive the group if they pass his trial. He then takes control of Serenity's mind to make her fight the group as part of the trial. Cursed Arm begs him to use him instead, but Hassan calls him unworthy. Hassan then sends Serenity, whose Spirit Origin values are increasing, at the group. After the group defeat Serenity without killing her, Hassan accepts the outcome, and reveals and introduces himself; Ritsuka decides to call him King Hassan. After Hassan cuts Romani's communications, Cursed Arm asks for his help in fighting against the Lion King while begging for forgiveness for entering the shrine. Hassan calls Cursed Arm wrong on two accounts, then he asks Ritsuka if they would fight against the Lion King. Ritsuka answers they are unsure, and Hassan asks if he and the other Hassans are enough. After Ritsuka answers the Hassans aren't enought, Hassan tells them to learn the truth of the Lion King, Ozymandias, and the Incineration of Humanity. He states he will join them once they've learned all that, saying he'll take care of Gawain. Hassan then tells the group to go to the Atlas Institute out in the desert where they'll find the answers they seek. He then prepares to behead Cursed Arm for his transgression, but he stops when Bedivere asks why he must execute Cursed Arm. Hassan answers he is the Hassan that kills other Hassans as the one who punishes Hassans who've been corrupted. He explains that a Hassan asking for his help is a declaration of them being unworthy of being Hassan, which Cursed Arm is well aware of. However, Hassan decides to postpone Cursed Arm's execution until the Lion King is defeated. He tells the group to head to the Atlas Institute before the Lion King's lance returns to its true form. He also tells them to restore the Holy Land and return the holy artifact before again concealing himself.

Exiting the shrine, Mash tells Romani of the Atlas Institute out in the desert. She explains to Ritsuka that the Atlas Institute is one of the three major schools of the Mage's Association specializing in Alchemy. Trismegistus, the Psuedo-Spiritron Calculation Engine that analyzes Chaldea, was a donation from them. Romani warns of the dangerous magical weapons in the Atlas Institute, but states it's necessary to go there to learn the truth. The group then proceed to travel back to the eastern village. However, as they travel back, Touta warns them that the village is under attack by Camelot soldiers. Cursed Arm goes on ahead as he tells Serenity to protect Ritsuka, and tells the others to save the villagers. Touta and Sanzang go to the village from its eastern side while Ritsuka, Mash, and Serenity fight knights as they head towards the village. After defeating the knights, the trio enter the village to find it in flames. Romani warns the scattered villagers will be killed if the enemy attacks again while Mash wonders where Arash is. The trio are then attacked by knights but are able to defeat them. Serenity states half of the villagers have already been evacuation, and assumes they're in a cave used in the case of evacuation. Meanwhile, Arash leads the villages to the cave as he asks for two to help him intercept the soldiers. He and another head to defend the village's entrance while leaving Rushd to lead the villagers. However, as they continue to defend the entrance, Arash's arrows are countered by Tristan. Suddenly Lancelot appears and kills the villager who was helping Arash, and proceeds to seemingly kill Arash with Arondight Overload

Meanwhile, Tristan confronts Ritsuka, Mash, and Serenity in the village. After introducing himself, he reveals he killed the village's men, and says he'll go after the others fleeing for the cave once he kills the trio. When asked by Serenity why he is killing everyone, Tristan answers he tracked her to village with his bow. He continues to guilt her that he wouldn't have found the village if she fled alone. Mash defends Serenity from Tristan, and they proceed to fight him. Unfortunately, Tristan overwhelms them thanks to his Gift, which he describes as an uncontrollable merciless blades that cuts all down. Bedivere then appears and attacks Tristan, angered that he killed innocents and burnt their village on the Lion King's order. Tristan reprimands him that King Arthur, while benevolvent, had only warned against going too far yet never forbade it. He continues Bedivere only saw the king's glory and not his horror, saying the king doesn't understand people's feelings. In a rage, Bedivere attacks him again, telling Tristan he'll stop him and confront the Lion King. The group fight Tristan again, but he still Tristan overwhelms until Sanzang, Touta, and Cursed Arm appear and attack him. Tristan states the Lion King wouldn't have taken action against the Saracens if they hadn't rebelled. He tells the group to look to the western sky, and they watch as the Lion King's spear, Rhongomyniad, destroys the western village. Bedivere asks Tristan if the Knights of the Round have gone mad, to which Tristan replies they cast away their humanity to follow their king's order. Stating the Lion King has succeeded in completely severing human emotions, he warns Rhongomyniad will strike the eastern village in five minutes, and sends his knights to kill the group. They defeat the knights, and Romani warns them Rhongomyniad is getting close to impact. Mash decides they need to evacuate the villagers before that happens, but Arash warns it is too late for that. He tells the group to head to the cave, and reveals to Bedivere that he knew of his reason for coming to the era. After the others go to the cave, Touta stays behind and watches as Arash uses Stella to destroy Rhongomyniad's blast.

Later, after the group mourns the loss of Arash, Cursed Arm reveals Hundred Faced had evacuated the majority of the western village before it was destroyed. Meanwhile, a village funeral begins, which Serenity wants the group to join in. However, Cursed Arm tells Ritsuka to leave the village, and warns Camelot will attack the village once word of Arash's deed reaches it. He implores Ritsuka to head for the Atlas Institute before that. Romani agrees with him, and says they need to find a way to counter Rhongomyniad. Agreeing with him, Cursed Arm says they will prepare for their assault on Camelot after evacuating the villagers. He tells the others he and Serenity will remain in the mountains until regrouping with the others before the attack on the Camelot. He then tells Mash he will spread word of Ritsuka to other Saracens. Cursed Arm then agrees with Romani to rendezvous in the village for final confirmations on assault once the others return from the desert. After Mash goes to tell Sanzang and Touta of their plans, Cursed Arm tells Bedivere that he'll never forgive the Knights of the Round, especially Tristan who he wants to kill. He warns him that he'll kill him as well if he tries to defend Tristan. Bedivere tells him that he will not defend Tristan, and says the injustices of the Knights of the Round is a responsibility held by it members. Due to that he asks Cursed Arm to treat him like an enemy if the Lion King proves to be the true evil. With Cursed Arm and Serenity staying behind, the rest of the group head for the desert.

In the throne room of the Lion King, Lancelot reports he has brought twelve humans fit for the Holy Selection, and says he'll join in defending Camelot. Agravain tells him he wants him to assist guarding the third, and thanks Lancelot for his work as the king's plans have reached its final stages. He continues the confrontation with Ozymandias is nearing, stating the third tower will be the key in protecting the royal caster. Agravain orders Lancelot to go to the third tower at once, Lancelot wishes to ask Lion King a question which she permits. Lancelot states how returned from attacking the western village village on Tristan's request as it was full of rebels. He then asks the Lion King why she unleashed Rhongomyniad on the western village as Tristan setting it ablaze was already excessive. He calls the act cruel, saying she never used Rhongomyniad on human settlements even with rebels before. Though he believes in the righteousness of the Lion King to use fear to speed governance given the circumstance, Lancelot calls destroying the village with Rhongomyniad to be unjust. Wishing to know her intentions in using Rhongomyniad on the village, Lancelot wonders if she was manipulated by Agravain. The Lion King however answer she used Rhongomyniad of her own volition as burning a village would only strengthen rebellion against Camelot. She continues she has no time for rebellions as Rhongomyniad is entering its final stages, stating the Tower at the Ends of the World will soon welcome them. The Lion King reveals the tower needs to be opened before Solomon enters the next stage of his plan after the Incineration of Humanity, which is about to occur. She further states she ordered the enforcement of the village, calling the Saracens' rebellion trivial since Gawain can kill them at the gates. Lancelot however calls the enforcement of the village to be unnecessary if the defense of Camelot is complete. Tristan return and criticizes Lancelot on his point as threats to the city still exist. He reports the eastern village wasn't destroy since Arash countered Rhongomynidad with Stella. He further reports the rebels have left the mountains and are heading towards the desert, believing they plan to join with Ozymandias. Lancelot offers to chase the rebels and capture them, accepting any punishment to be given for his failures afterwards. Agravain states he'll assign others to pursue, and orders Gawain to restrain Lancelot. He continues that Lancelot will be relieved of his duties and imprisoned until the Lion King interrupts and asks Lancelot if he can capture the rebels. Lancelot answers he can, and the Lion King orders him to capture the rebels and return before the castle's walls appear. After Lancelot leaves, Tristan reports that he encountered Bedivere in the eastern village. Mordred and Gawain also reveal they encountered Bedivere, but they didn't report it as they considered his appearance insignificant to Lion King's plans. Agreeing with this, Agravain orders Gawain to the return to the gate as Tristan states Bedivere isn't his former self. Agravain then orders him to guard the castle, and orders Mordred to sweep the city's surrounding. He tells the Lion King to not let Bedivere concern her, but she is confused as she doesn't know who Bedivere is.

Meanwhile, the group travel through the wastelands as they fight monstes, and advance to the desert after slaying them. As a sandstorm rages across the desert, the group use a map locate the Atlas Institute given to them by an agent of Hundred Faced. Through the agent, she revealed a westerner wearing a black cape and turban has been spotted by the institute, and warns Ozymandias' divine beasts wander near it. As Mash considers the possibilty of the westerner being, Sanzang got lost and is being attacked by sphinxes. After driving the sphinxes away, Mash realizes they are nearing the Atlas Institute. Later, the group notice a large number of sphinxes, and Sanzang suggests using Touta's Bale of Inexhaustibility to feed them as a distractions. Ritsuka and Touta reject it as the latter senses a Knight of Round with others nearing. The Knight is revealed to be Lancelot as he confronts the group and tells them he has come to capture on the Lion King's order. Bedivere asks him why he serves the Lion King as he calls her actions not to be those of the original King Arthur. Lancelot however doesn't answer as he orders his troops to detain the group. He then agrees with Bedivere that the Lion King's actions are not that of King Arthur. He continues he swore allegiance to King Arthur, not the Lion King. Hearing Lancelot's answer, Bedivere and the others fight him and his knights. However, Lancelot is too much for the group, and they decide to they need to retreat. However, as Lancelot prepares capture them, a giant illusion of Nitocris who tells the group to run while the knights are distracted. The knights try to chase after them, but they run into a sphinx nest along with the group. After defeating the sphinxes, the group fall through a pitfall trap. Upon landing, they are greeted by Sherlock Holmes who reveals they're in the Atlas Institute.

After deducing the group's identities, Sherlock reveals he left the notes regarding the truth of Servant summoning that Ritsuka and Mash learned of in London. He then states he must solve a case requested by Charles Babbage before he can join Chaldea. After revealing he activated the pitfall trap, Sherlock tells the group he can came to the institute in search of the truth that Hassan mentioned, which it is in the central area. Warning the way there is akin to a labyrinth, he decides to lead the group, and asks them to destroy any traps encountered. Later, after the group defeat some enemies, Sherlock explains to Ritsuka that the Atlas Institute is focused on investigating the principles of the world. They created seven world-destroying weapons called the Seven Taboos, which was due in part to their directors, like Zepia Eltnam Oberon, going mad failing to create a world-protecting tool. These weapons were sealed along with Atlas' other failures inside the facility the group is currently in. Sherlock theorizes the institute appeared in the Egyptian desert in the Singularity is due to the origin of Atlas's alchemy being tied with the progenitor of Magecraft in Egyptian mythology, Isis. Continuing towards the center, the group notice an optical illusion that Sherlock explains as Atlas's way of preventing any from leaving with their tools. The only exception to this rule is the Seven Contracts, which allow for Atlas's cooperation with whomever is hold one. However, as Sherlock explains Atlas recovered four of the contracts by 2000 AD with three still missing, the institute's defense mechanisms activate. After the defenses are destroyed, Sherlock wonders why she can't activate her Noble Phantasm. Ritsuka explain it's due to her not knowing the Heroic Spirit fused with her's True Name. After stating not knowing the True Name isn't the issue, Sherlock states he has no information on Solomon. Ritsuka reveals they met Solomon personally as Sherlock demands to know everything about that encounter. Ritsuka and Mash explain they can't remember much beyond Solomon's appears yet Ritsuka remembers he was missing something. Sherlock then requests Mash to sketch a picture of the Solomon she and Ritsuka saw as they continue to walk. He explains she would normally be curse for doing so but the institute has counter-measures against outside curses. Mash agrees with his request, and tell him that Solomon's personality was inconsistent and changed abruptly. After she tells Sherlock of her conservation with Solomon, he compares Solomon's personality to a mirror that reflects the person speaking to it. Mash states how Solomon said he no interest in humans, which concerns Sherlock as the truth of Solomon. He continues that Solomon has already won since he destroyed humanity, explaining it as the reason he even showed himself. He furthers explains Solomon's disinterest in humans is also due to moving to his next project after incinerating humanity. Sherlock fears what the true nature of Solomon's next project could be.

As the group finally near the institute's center, Sherlock explains the two reason Hassan sent them here. The first is to learn of the Lion King's objectives and Rhongomyniad. The second is to learn a part of the mystery behind the Incineration of Humanity. He states he is prepared answer both of these, but defenses activate once again. After destroying the defenses, the group reach the center where Tri-Hermes, which Trismegistus is based on, is. As Mash wonders why the equipment is still functional, Sherlock explains it is because the institute is from her and Ritsuka's era. He then accesses Tri-Hermes' records to discover what happened in the Fuyuki Holy Grail War of 2004 as it's an important factor to truth of the Incineration of Humanity. The course of the war nor its conclusion is known with the only victor, Marisbilly Animusphere, being recorded. Sherlock also reveals that Romani served as Marisbilly's assistant during that time before joining Chaldea to quickly become head of the medical division. He calls Romani to be strange as he cannot find any records of his personal history before the Holy Grail War. Sanzang asks Sherlock what Marisbilly wished for, but he answers that it wasn't recorded though he assumes it was fortune based on Chaldea's future successes. Sherlock states Romani has a possible connection to the Incineration of Humanity, and asks the others not to tell Romani what they heard due to Sherlock's own mistrust of him. He goes on to say that Romani knew the conclusion of the Grail War yet kept it secret. Later, Sherlock decides to reveal to Mash the True Name of the Heroic Spirit fused with her despite Bedivere's wanting her to learn it on herself. However telling Mash the True Name of the Heroic Spirit, he reveals Chaldea used the Round Table to stabilize their Heroic Spirit summoning system as it was a place where heroes gathered. He further reveals that the core of Mash's shield is the Round Table itself. He then reveals that the Heroic Spirit who fused with Mash is Galahad, the Knight of the Round who alone succeeded in finding the Holy Grail. Seeing Mash's gratitude, Bedivere agrees with Galahad's decision to entrust his power to one closet to him regardless their differences of time and race.

Afterwards, Sherlock warns Tri-Hermes only has enough power for one more query before it shuts down. Using Tri-Hermes to learn what Rhongomyniad is, he asks Bedivere if he knows anything about it. Bedivere answers he only knows it was one of the holy artifacts owned by King Arthur, and that Merlin called it the "Tower at the Ends of the World". The Tower is a pillar of light which stands at the world's edge far west of Britain. Answering Sanzang's confusion about Rhongomyniad being both lance and tower, Sherlock reveals the tower is Rhongomyniad's true form while the lance is a terminal to access the tower's Authority. He continues Rhongomyniad is one of several towers that keeps the current fabric of reality on the world. Sherlock then reveals the Lion King plans to use Rhongomyniad to create an ideal world at Camelot by gathering absolutely pure humans. He states that according to Tri-Hermes' calculations, Rhongomyniad can store up to 500 souls, and reveals Camelot is Rhongomyniad itself, sealing people inside it once they enter. Answering Bedivere's concerns, Sherlock reveals the people inside the Tower were gathered as ideal examples of humanity's virtue to be sealed away forever once Camelot returns to being the Tower. Touta says the Lion King and her army will be sealed inside the Tower as well, believing the people of the Holy Land will be safe then. However, Sherlock corrects him that the rest of the era will become the Ends of the World in exchange for the Tower's completion, which has already begun. He says the reason the Singularity is an exception within an exception is because it is exists nowhere in the world. Sanzang realizes the reason nothing exists beyond the desert is due to the era having already been separated from human history. Sherlock agrees with her, and states the Lion King's ability to destroy one of the Foundations of Mankind to create her ideal world is that of a god. The group then decide to return to the surface to stop Rhonogmyniad's completion, and to ask Lion King's intention. However, the institue activates it strongest defenses to prevent them from leaving. After the defenses are destroyed, Sherlock wonders why Solomon chose 2018 to begin the Incineration of Humanity, saying Solomon had a reason to burn the 3000 years between 1000 BC (Solomon's era) and 2018. He also theorizes that Solomon, even with his power to see the future, couldn't see past the year 2018, which Ritsuka believes is due to Solomon having destroyed the world.

Returning to the surface, the group are confronted Lancelot and his knights. He tells them to surrender otherwise he'll kill them for resisting. Bedivere prepares to fight Lancelot as they are both Knights of the Round. However before they fight, Bedivere asks Lancelot if he knows the Lion King's intentions with Rhongomyniad. He continues that Camelot is the "Tower at the Ends of the World" itself that gathers the purest of humans and quarantines them. Once that is achieved the era will destroyed; Bedivere calls the Lion King's intent something beyond human. Lancelot lowers his sword upon hearing as Mash initially believes the Knights of the Round weren't informed of the Rhongomyniad. However, Lancelot suddenly attacks Bedivere, and expresses his surprise that others know of Rhongomyniad. He continues he can't can't let the group as they would spread unneeded fear. Bedivere is shocked Lancelot still serves the Lion King despite knowing of Rhongomyniad, and asks him if even knows her intentions with it. Lancelot reveals he knew of the Lion King's intention to use human souls to open the Tower as she announced to the the Knights of the Round when she summoned them. He continues he and the other knights slaughtered the Crusaders, and decided to become the enemies of the era despite knowing the Lion King's intentions are inhuman. Lancelot then attacks Bedivere again, but he is blocked by Mash. Influenced by Galahad, Mash is infuriated that Lancelot still prides himself as a knight of King Arthur despite knowing of the Lion King's plan. Lancelot realizes Mash's shield and manner of speech is that of Galahad when she challenges him to a duel. After being defeated, Lancelot surrenders, and Ritsuka decides to him Lancelot ally. Before that though, Lancelot wishes to show the group a place which will become utterly unknown if he disappears.

Escorted by Lancelot's unit, the group travel for half a day to a secret refugee camp. Lancelot reveals the people in the camp are those who weren't chosen to enter Camelot, stating the Lion King never order him to execute them. He also reveals a number knights had disobeyed the knight, so Lancelot had them guard the refugees. Suddenly, da Vinci appears before the group, and she reveals that she survived thanks to Lancelot protecting her. Mash then tells Romani, while keeping Sherlock's involvement a secret, what they learn in the Atlas Institute, and sends him information about Rhongomyniad. Saruhan then appears, and da Vinci tells the group she had him assist the other refugees fleeing from Camelot's gate when Ritsuka and Mash visited it earlier. She also had him look into the state of wasteland as he thanks her for digging a well. After some sparing, Mash explains the truth of Rhongomyniad to da Vinci. Da Vinci explains the Lion King's intent is to create an isolated space for the purest of humanity to continuing existing able to withstand the Incineration of Humanity. Lancelot says the Knights of the Round believed that the Lion King's ideal was righteous. In response, Sanzang calls the Lion King's intention as it takes people's choices away yet the Knight of the Round accepted it because they believed in the old King Arthur. She then asks why King Arthur became the Lion King, but Lancelot reveals the Lion King already existed when she summoned them. When Lancelot mentions some knights considered the king to be mad, da Vinci corrects him that the Lion King no longer possesses a sense of reason. Lancelot believes it is due to Agravain's manipulation, but da Vinci only mentions Saruhan said Agravain took over the merchant's guild. She then reveals the King Arthur became the Lion King due to holding Rhongomyniad for too long, which changed her existence to a Divine Spirit. Da Vinci also explains the king would've focused on improving life in Camelot if she still had human reasoning, but instead her reasoning is that of a god who only sees value in humanity not humans. Angered by this revelation, Lancelot asks why King Arthur turned into a god as he speaks of her original intentions to bring peace and prosperity to Britain and its people. Romani then states the Lion King's intention to create a world without humans would disrupt human history even if Chaldea is able to restore humanity. Lancelot offers to fight the Lion King, but da Vinci states the Knights of Round receiving a Gift from the Lion King prevents them fighting her as they'll be destroyed. Mash decides the group need to join the Hassans in attacking Camelot, but Sanzang calls that suicidal given the difference of their forces and the matter of Rhongomyniad. Ritsuka and Mash then suggests they have Ozymandias join them, but Bedivere and da Vinci are against that idea. Da Vinci says the group will have fight Ozymanidas anyways once the Lion King is defeated. However, Lancelot suggests convincing Ozymandias that joining the group will benefit him given that Egypt will disappear if the Lion King isn't defeated. Later, they prepare to leave for the desert with the group consisting of Ritsuka, Mash, Sanzang, Touta, Lancelot and his knights. Meanwhile Bedivere, on da Vinc's request, is making contact with the Saracens, starting with the eastern village since he already knows its leader Cursed Arm. Lancelot order his other knights to stay in the camp until Bedivere brings back word from the Saracens about their proposal to ally with Ozymandias. If the proposal then the knights will move to the hidden valley near Camelot and stand by. Using da Vinci's newly built vehicle, the Bastiyan, the group depart for the desert.

Ritsuka, Mash, da Vinci, and Sanzang ride in the Bastinyan while Touta and Lancelot and his troop follow on horseback. After slaying some monster they ran into, the group eventually near Ramesseum Tentyris, and rest for the night before meeting Ozymandias tomorrow. While everyone else is sleeping, Ritsuka tells da Vinci what they learned of in Atlas involving Marisbilly's participation in the Grail War of 2004 and his relations with Romani. Da Vinci says she was summoned in the Chaldea after the war, and only met Marisbilly very briefly before he died later that same year. Mentioning that the relationship between Romani and Marisbilly was unknown to her, she speaks of how Mash's condition became worse after being fused with Galahad. Da Vinci reveals Romani helped with the process on Marisbilly's request, though he previously had no knowledge of such experiments despite years of service in Chaldea. She was infuriated to learn of the unethical experiments performed in Chaldea, but she decided to stay to help Romani from overworking himself. Da Vinci states Romani is a regular human like Ritsuka, but he is hiding something akin to the Grail. However, using that something will cause Romani to die or something similar. Da Vinci assures Ritsuka that Romani is an ally with no ulterior motives despite his past being unknown. She then tells Ritsuka to go to sleep since their negotiations with Ozymandias are tomorrow.

The next day, the group arrive at the temple, and da Vinci sends a messenger to Ozymandias. While waiting for Ozymandias' reply, Mash asks da Vinci what the message was, to which she answers it was a request for him to join them and be prepared for their arrival. After Touta mentions Ozymandias would see the request as a chance to test the group's strength, a group of sphinxes storm of the temple gates. While Lancelot and his knights fight the sphinxes, the group enter the temple with Mash leading them to the throne room. However, Sanzang mentions the temple has the same feel as Camelot, meaning Ozymandias can isolate himself like the Lion King. However, Nitocris suddenly appears, claiming Rhonogmyniad is powerless again her mirror. She then greets the group who then fight her and her summoned monsters as a trial to gain an audience with Ozymandias. After she's defeated, Nitocris allows the group to meet with Ozymandias. In the throne room, Ozymandias congratulates them on their victory over Nitocris, and asks Ritsuka why they've come. Ritsuka mentions the message they sent earlier about becoming allies, but Ozymandias answers he thought the message was a joke. Sanzang then mentions how she heard tales of how Ozyamndias differs from the Lion King as he prioritizes the lives of his people. However, she criticizes him for isolating his people inside the temple to protect them instead fighting the Lion King because he can't beat her. Ozymandias counters that due to the Incineration of Humanity it's pointless to defeat the Lion King alone. He says he'll only protect his people as the rest are not his concern, but Sanzang reprimands again for ignoring the world's destruction like the Lion King. Intrigued by what Sanzang said, Ozymandias decides to test the group's stength and resolve to save the world. With the Grail in hand, he pours some of his blood into it and drinks it to incarnate himself into Amon. However, he grants the name Amun-Ra onto Amon temporarily turning him into a Divine Spirit. Answering Ozymandias's test to prove they can defeat the Lion King, the group fight Amun-Ra. Unfortunately, the temple supplies Amun-Ra with an infinite amount of Magical Energy to instantly regenerate any wounds inflict by the group. However, thanks to Sanzang unlocking her full power, they are able to defeat Amun-Ra. Reverting back to normal, Ozymandias congratulates the group on their victory when Nitocris enters the room. Although they prove their strength to fight the Lion King, he decides to fight the group again with Nitocris to prove they'll be worthy allies. After being defeated, Ozymandias admits he's like the Lion King in trying to protect his people alone. Giving the Grail to Mash, he states the retrieval of the Grail will not restore the era as they must stop Rhongomyniad to restore it. Ozymandias then lends his army of sphinxes for the assault on Camelot, but says he won't join the battle personally as he'll have other matters to deal with. When Mash mentions King Hassan, he reveals he originally waged war with the Saracens as he expanded the desert. However, as he plotting his next move, Ozymandias was decapitated by Hassan. But since the fight occur in his temple, he didn't die and the wound was about healed when the group first arrived in the temple. Ozymandias tells the group he would've accept their proposal if they said they knew Hassan earlier.

Outside the temple, Lancelot tells Ozymandias to march his army to Camelot from the west four days from when the group arrives at the city at dawn. Ozymandias assures him that his army will arrive at the allocated, and send his beast trainers to further discuss the plan with the group. Returning to the eastern village three days later, the group tell Bedivere and the Hassans that they've gained Ozymandias cooperation. Serenity says they've gathered seven thousands followers, and Hundred Faced says two thousand people in Camelot are secretly supporting their rebellion. She then mentions it was difficult to gather followers at first, however an innumerable amount soon joined due to being saved from the Holy Execution by Ritsuka and Mash. As Touta leaves to prepare a meal with Sanzang following, Cursed Arm goes over their strategy with Ritsuka. The group will go into the wastelands where they'll the forces scattered there, then they will march towards Camelot. Lancelot offers to lead the army as knows of blind spots to hide from the patrol until they arrive in the territoy of Camelot, which has no blind spots. Cursed Arms agrees him, and says they'll rest further from the city before marching towards during the night. Their army will breakthrough the Lion King's forces, and force their way into the city. After they capture the city and its castle, Ritsuka's group will go kill the Lion King. With discussions over, the Hassans fight Ritsuka, Mash, and Bedivere to prove their resolve once more.

After defeating the Hassans, Ritsuka talks with Sanzang while Mash speaks with the Hassans and Touta after putting Rushd to bed. Meanwhile, Da Vinci and Lancelot discuss how to break through Camelot's main gates with her suggesting they blast through it with a Noble Phantasm. Lancelot reveals though that the gates render malicious attacks and evil powers ineffective, even the greatest holy sword wouldn't dent them. However he says they'll build a scaffold and use it climb over the western wall once Ozymandias' divine beasts break it down. Da Vinci however is concerned about both the difficulty of breaking down the wall since it's Rhongomyniad, as well as Mordred and her forces who patrol the city's outskirts. Lancelot assures her that his unit will handle Mordred's knights as they're less proficient than his, who'll assist scaling the wall afterward. Da Vinci tells him she and the others will wait by the castle wall while protecting their allies until he arrives. Once inside her group will head straight for the Lion King while possibly fighting Tristan and Agravain along the way. Lancelot is concerned that Agravain may be planning to use them to weaken the Lion King's power, believing Agravain only acts in self-interest. He mentions Agravain secretly controlled the goverment in both Britain and the Holy Land, saying he'll kill Agravain out of a belief he manipulated the king. However, da Vinci tells Lancelot that if Agravain truly acted out of self-interest then Camelot would've been a bureaucratic city with useless functions, which the group could take advantage of. Instead Camelot became a city without self-interest with no holes in it for the group to take advantage of. Later, Mash finds Bedivere crying while looking for Ritsuka. Bedivere tells her Ritsuka isn't with him, and asks her to stay and talk when she decides to search elsewhere. He reveal he lost all physical sensation years along, and that he was crying out of fear whether his actions are right or not. Mash realizes he fears meeting the Lion King, which Bedivere concurs with. He then asks her, as Knight of the Round, if she is also afraid of confronting King Arthur. Mash answers she is indeed afraid of fighting the Lion King, but asserts she wants to answer the trust Galahad placed in her and Ritsuka. Happy to hear her answers, Bedivere admits he previously thought Mash was a counterfeit like him when she said she was Demi-Servant. As Mash becomes confused by his statement, Bedivere reveals he committed an unforgivable crime, and came to the era to atone for. He continues how he had ignored the people's distress to focus on meeting the Lion King until he saw Ritsuka and Mash fighting the knight outside Camelot's gates. He reveals he joined Ritsuka and Mash because they were the best way for him to encounter the Lion King. Bedivere then wonders if his journey will be rendered meaningless when it ends, but Mash tells him it will. He then tells Mash that her Noble Phantasm's true nature is to protect people not to repel enemy attacks. Telling her to focus her mind on those she wishes to protect instead, Bedeivere says her shield's true nature is the path to the true Camelot.

In the wastelands near Camelot, the group go over their strategy once more when Romani reports the city is prepared for them. Ritsuka, Mash, da Vinci, and Bedivere will head for the main gates with the infantry. Lancelot will head his army of knights while Sanzang and Touta will travel together. Once Cursed Arm reaches the castle wall, he'll thin out the archers placed there by Agravain. Ozymandias' sphinx army will create a diversion on the west side of Camelot, which the allied forces will use as an opportunity to attack. Lancelot's knights will advanced before Ritsuka's group, though Lancelot warns they'll suffer heavy causalities from the archers. He suspects only sixty percent of the allied forces will make it to the gates, but they no choice but to attack the main gates. Bedivere says they can't wait for Hassan to arrive to fight Gawain, suspecting Lancelot will have to fight him. However, Lancelot warns they cannot wait for nightfall either to fight Gawain, but Sanzang offers her and Touta's assistance. Accepting her help, Lancelot commands the allied forces to prepare to advance when a sandstorm suddenly appears from the northern sky to envelop Camelot. Cursed Arm realizes the storm is thanks to Hassan's power. With storm making both sides' archers useless, the allied forces advance onto Camelot as fast as possible.

As the allied forces fight through Camelot's army, Gawain orders a messanger to tell the archer on the wall to only for aim for enemies directly below them unless they'll shoot their allies. A soldier reports to that the right flank's Third Unit is requesting backup as they're pelleted by grain and unable to move. Gawain tells them not to engage as the enemy is likely a Servant, and orders the soldiers to hold rank until Mordred's unit. Another soldier then reports the First Unit at the left flank are becoming overrun by Lancelot and his knights. Gawain orders the soldier to tell the First Unit to retreat and regroup with the Fourth Unit then rally with the troop at the right flank. Gawain announces he'll stepped onto the battlefield and incinerate the enemy with Galatine. However, Hassan suddenly and kills the soldiers that was praising Gawain. Gawain realizes he's behind the sandstorm, and attacks Hassan believing he is invincible as long as the sun shine. Hassan easily parries his attack though with his cape to Gawain's shock. Hassan introduces himself, and asks Gawain if the sun still shines.

Meanwhile, the allied forces prepare ladders to climb over Camelot's wall, but the ladders are destroyed the instant they'e mounted. As well the sphinxes attacking the main gate are unable to put a scratch on it as Bedivere reveals Camelot only grants access to those with righteous hearts. Enemy forces are quickly eliminating the allied forces while Hassan is fighting Gawain. Da Vinci asks Bedivere to use Airgetlám oo the gate, but Bedivere states it has no effect on Camelot. Suddenly Enforcement Knights under Agravain's command appear and attack Ritsuka's group. Meanwhile, as the allied forces are overwhelmed by the enemy, Sanzang tells Touta to move to the wall past the front gate. As Touta takes her to the wall, Sanzang prepares her Final Buddha Palm to destroy the gate despite knowing it'll kill her. Then at the gate, Sanzang unleashes her Noble Phantasm using all her power to destroy the front gate, which allows the allied forces to advance. Meanwhile, Touta takes Sanzang to the western wall, and they share one last moment before she disappears.

Inside Camelot's castle, a soldier reports to Agravain that the front gate has been destroyed. He says the Lion King should informed, asking Agravain to tell her to use Rhongomyniad before the allied forces arrive in the city. Agravain however tells the soldier there's no need as Tristan is in the city while Mordred is outside. He orders the soldiers to continue fighting until the sandstorm giving the allied forces an advantage disappear. However, the soldier reports that Mordered's unit has been routed by Lancelot's unit. Meanwhile, Ritsuka's group finally enter Camelot as Romani warns there's a mass of knights akin to divine constructs created by Rhongomyniad are approaching. Noticing there are no civilian in the city, Mash wonders if they have already been absorbed by Rhongomyniad. Da Vinci says Camelot's surroundings would at the world's edge if that were true, believing the civilians were evacuated before the battle started. After the group defeat the knights, Romani reports the allied forces are inside the city and moving towards its center. The group continue towards the castle before they can encounter any Knights of the Round. Meanwhile, in the throne room, Agravain reports to the Lion King that the allied forces have entered the city after destroying the main gate. As the Holy Selection is finished, he implores her to open the way to the Tower, and create the utopia she failed to create in Britain. Complying his request, the Lion King fully activates Rhongomyniad.

Outside, the group near the castle, but they're stopped when the Tower suddenly appears to surround it. Romani reports that he's detecting a gravitational collapse from all corners of the era, and warns the ends of the world are encroaching onto Camelot. After the group defeat some enemies, Romani reports the allied forces are pinned at the front gate as the enemy has been rallied by the Tower's appearance. He implores the group to find a way to remove the Tower before the allied forces are eliminated. However, Mordred suddenly appears and states it's impossible to remove Rhongomyniad as she attacks Bedivere. She prepares to fight the group like she promised earlier, but Bedivere tells Mordred they have no time to waste on her. He tells her further that it's disgraceful that she calls herself King Arthur's heir. He asks her if she thinks nothing of the Lion King trying to burn the world along with her own me. Mordred retorts that the Lion King has no need for an army as her ideal city is one without war. She continues that the army will die protecting Camelot, saying they'll become the Foundation of Humanity created by the Lion King. Mordred states that is honor of one of the Lion King's Round Table, which Bedivere never became a part of. She then becomes infuriated at Bedivere for being present at King Arthur's final moments, claiming he doesn't understand the other knights' feelings due to that. Enraged that Bedivere appeared from nowhere after everything that happened, Mordred fights the group. After being defeated, Mordred still tries to fight despite her wounds, claiming only King Arthur can kill her. Bedivere stops though as he tells her dream to truly serve King Arthur will never come true since she's the Knight of Treachery. He states the reason he was at Arthur's final moments was because he was weak and unable to save him. Bedivere claims both he and Mordred were weak and incompetent knight who were never worthy of being by the king's side. He then tells Mordred that her dream to serve the king despite being hated by the king means she surpassed him in that respect. Claiming she lived a purer life than a sinner like him, Bedivere finishes Mordred after asking forgiveness for ruining her dreaming. Unfortunately, the group finds it's impossible to remove the Tower from the outside unless they defeat the Lion King who's at the center. Suddenly though, Ozyamandias and Nitocris in Ramesseum Tentyris, direct all of its Magical Energy to attack the Tower. However, the attack is blocked by the magical walls surrounding Camelot, so Ozymandias decides to use his own Spirit Origin to accelerate the temple towards the city. After the walls are eventually destroyed, Nitocris reports the Tower is preparing to attack as she sees Ozymandias is beginning to fade. Nitocris uses Anpu Neb Ta Djeser to block the light from the Tower. Ozymandias uses that chance to crash the temple into the Tower to finally destroy it. With Nitocris' mirror broken and Ozymandias having used all of his energy, the two pharaohs disappear.

Gawain and Hassan continue their fight with an hour having passed since it began. Hassan suddenly decides to end their fight, and stops the sandstorm, claiming there's no need for it anymore. Gawain attacks him with Galatine, but Hassan easily deflects it. Realizing the tremendous power Hassan possesses, Gawain asks him why he didn't stop the Lion King before Camelot was built half a year ago. Hassan answers the will of heaven hasn't tasked him to fight the Lion King, implying it was tasked to Ritsuka and the others instead. He tells Gawain to the go to the castle and confess his sin before Rhongomyniad consumes the world. After Hassan leaves, a soldier tells Gawain the rest of the army will go after the rebels. However, Gawain orders the soldier to hold the gate while he returns to the castle. He continues the battle's outcome will be decided within the hour, and tells the soldier to take his men and head north if the castle becomes ablazed. Ordering the soldier to take as many home as possible, Gawain states the expedition was doomed from the start. After thanking the soldier for his service, Gawain moves into the city.

Inside the city, the group realize Ozymandias had destroyed the Tower, believing the enemy is now demoralized. However, Romani tells them the era is still being destroyed as Rhongomyniad is still active. He continues that what was destroyed was merely Rhongomyniad's sheath, and states the era's collapse won't end unless the Lion King is defeated. The group decide to hurry to the castle when Lancelot arrives in the city. Lancelot reports their allies now control the front gate, with many of the enemy archers on the wall having surrounded. After being told Gawain returned to the castle, da Vinci decides they need to defeat the Lion King before Gawain arrives. Instead of joining the group, Lancelot decides he'll look for Agravain as he believes he is too dangerous. The group decide to take a direct route into the castle while Lancelot takes a back route and capture Agravain. As they towards the castle, Bedivere talks about Agravain was always viewed as a cold villain, given his disdain for people. He continues the colapse of the Round Table and the fall of Camelot began after Agravain died. Bedivere states King Arthur needed Agravain, perhaps even more than Merlin. Mash agrees with Bediever's assessment of Agravain, revealing she felt relieved when she saw him at the fort. It felt as if her Spirit Origin was telling that as long as Agravain was around then King Arthur would be fine. Bedivere mentions Galahad was an excellent judge of character, who truested Agravain because he felt Agrvain's heart had some justice in it. Suddenly though, he blocks a surprise attack by Tristan from the roof of a building. Tristan comes down and fights the group after telling Bedivere that the Round Table he knew existed in the era. Unfortunately, the group still can't defeat him as he claims he only needs to keep them busy until Rhongomyniad completes its task. Fortunately for the group though, the Hassans arrive to fight Tristan. The group then go ahead to the castle, assured by the Hassans that they'll defeat Tristan.

After they breakthrough a group of knights guarding the castle, the group enter with Bedivere leading the way due to his familiarity wih it. Meanwhile, the Hassans continues their fight with Tristan, with him having killed 95 of Hundred Faced's personas. Serenity then activates her Noble Phantasm to poison him, stating Hundred Faced and Cursed Arm were distracting him until she activated it. Hundred Faced reveals they discovered Tristan's death was caused by poison, and prepares to finish him off as she believes he's weakened. However, Tristan surprises her when he kill both her and Serenity. He reveals his Gift, "Reveresal" was originally intended to make him heartless but it also reversed his weakness to poison. Realizing their attack was in vain, Cursed Arm unwraps his right arm, and he grabs Tristan's arm after direct hit from him. Suddenly though, Cursed Arm's arm begins to move on its own to Tristan's surprise. Cursed Arm reveal he stole the arm from Shaytan, having controlled it through a curse. With the curse now removed though, he states Shaytan will take over his body and devour him with Tristan being the sacrifice. As Tristan agonizes at being devoured, Cursed Arm tells him how the Hassans protected the people of the Holy Land without the need for Gifts nor utopia. However, Tristan is able to use Failnaught to free himself, but he realizes Shaytan has already devoured half of him.

Inside the castle, the group near the throne when they're confronted by Gawain. Gawain states with the appearance of the Tower, each of the Knights of the Round to their own devices on how to serve the Lion King. Bedivere replies to him that he would remain the king's sword, and not even stop him from revealing the king's mistakes and denouncing Camelot. Gawain reveals the Lion King told him he could do anything after she summoned him, which made him happy to hear. He claims it was mere coincidence Bedivere was there for King Arthur's final moments. He continues that his inability to cast away his personal grudges had caused the king's death. After saying he cannot repeat that foolishness again, Gawain states the Lion King wouldn't call herself if she was the same King Arthur as before. He reveals Percival, Kay, Gaheris, Palamedes,, and had revolted against the Lion King after being summoned instead of accepting her proposal, which he saw as their way of showing their loyalty to King Arthur. Gawain then reveals they were all killed by him and the other Knights of the Round serving the Lion King. He states the Knights of the Round were branded as sinners from the moment they pledge their loyalty to Lion King and helped her to destroy the world. Claiming he is now a knight serving the Lion King instead of King Arthur, Gawain asks Bedivere what his sword is for. Bedivere responds that right arm is the end of his loyalty and proof of a sin he couldn't erase. He continues that his arm was for the sake of truly saving the king who walked alone. After hearing Bedivere's answer, Gawain fights the group as he calls Bedivere the last remnant of the old Round Table and chivalry. After being defeated, Gawain claims it as the fate of a disloyal knight like him. Bedivere tells him that he is more loyal than any other knight, who like himself admired the king rather than the concept of honor. After hearing his reply, Gawain asks Bedivere why he appeared now at the end, claiming the king could've regained her heart if he was around. He then disappears after telling Bedivere he resents from the bottom of his heart, which Bedivere agrees with. Meanwhile, Lancelot confronts Agravain, saying he'll make him pay for the atrocities he committed in the name of the king. In response, Agravain suddenly attacks Lancelot with the power of Madness Enhancement he gave his knights. He reveals how he became a Knight of the Round through the machinations of his mother, Morgan le Fay, despite not wanting to be one. His purpose was to steal the throne from King Arthur and give it to Morgan. He agreed with her as he wanted to Britain to continue on with a strong king, using King Arthur to that end. Continuing to attack, Agravain states how he needed a king who'd labor and extend Britain's life even for a little bit. Not caring who was king, he used King Arthur as the best way to achieve his goal. Speaking of his misogyny, misanthropy, and hatred of love, Agravain reveals how relieved he felt when he fear being resented by the king. However, he felt unfathomabely empty upon learning of the king's secret when exposing Lancelot and Guinevere's affair. He then suddenly mentions his misogyny, which resulted from his mother's scheming and Guinevere's affair with Lancelot. Agravain continues he will always hate women, humans, and the emotion of love. He then reveals he had relieved at the fear of being resented by the king. However, he states how unfathomable empty he felt when he discovered the king's secret when exposing Guinevere and Lancelot's affair. Agravain then contines fighting Lancelot while claiming it's punishment for betraying the king once again.

Entering the throne room, the group see the Lion King, Artoria Pendragon, sitting on her throne. Artoria asks who they are and their purpose for coming before her. Directly asked by Ritsuka answers they've come to correct the course of humanity, which she states is the same as killing her. Artoria continues how Ritsuka was not chosen by Rhongomyniad as their soul is good yet commits, which is the same as being evil. Claiming Ritsuka's soul is unneeded in her utopia, she unleashes the storms at the Ends of the World from behind the throne. Da Vinci realizes Artoria was at the Ends of the World from the very beginning as the king stands from her throne and prepares to fight. Asked by Ritsuka why she's abandoning the world, Artoria answers she is doing so to help humanity survive. She continues the history of the planet will come due to Solomon's machinations, which goes against her purpose. Artoria states gods like her are born from humans, so they must be protected at all costs. Claiming to care for all humans, she reveals her ideal to give humans eternity by gathering, freezing, and archiving the purest of those souls inside Rhonongomyniad. After being rejected by Ritsuka, Artoria asks Mash if she understands her ideal as she explains human lives are finite. While Mash struggles to answer, Romani implores Ritsuka to destroy Rhongomyniad as Artoria's mentality is now of a god who no sense of human values. The group then fight her, referring to her now as Goddess Rhongomyniad. Unfortunately they struggle against Goddess Rhongomyniad with her massive magical energy damaging Sheba, and her Authority bears down on the group. She tells them the Ends of the World are near as she claims happiness will granted to humanity from giving eternity. She again explains her ideal to protect humanity by freezing and storing them, seeing it as the ultimate conclusion of her ideal. Mash rejects her concept of happiness as she recalls all the people in era that struggled to live regardless of the issues. She continues that life isn't meaningless because it ends, and challenges Goddess Rhongomyniad to fight her. Complying with her request, Goddess Rhongomyniad launches Rhongomyniad at her when Mash activates Lord Camelot.

In a flashback of Bedivere's past, it is revealed that Goddess Rhongomyniad is an Artoria from a parallel world. Differing the Artoria who went to Avalon, she had stayed behind on the earth, and eventually turned into a Divine Spirit due to Rhongomyniad. Merlin knows the former while Bedivere knows the latter. Normally, Goddess Rhongomyniad is a Artoria who would've never manifested yet she was able due to Singularity's influence. Bedivere had searched for the Artoria he knew, and eventually ended in Avalon after exhausting himself. With his body and soul damaged yet his mind intact, he was helped by Merlin so he can complete the task he failed to complete. Merlin had cast a spell on Bedivere to deceive mainly the Knights of the Round from discovering his true idenity, otherwise they'll awake to the truth of the Lion King. He was warned that he'll die regardless of the outcome, and that his soul had been exhausted and ousted from the cycle of reincarnation. Before he was sent to the Singularity, Bedivere was given Airgetlám by Merlin after it was changed from something else, though he was warned it would use his soul as fuel.

As Mash tries to block Rhongomyniad, Bedivere walks to her and tells her that her shield, which manifests the true Camelot, shall never break as long as its wielder's heart remains pure. He tells her that she isn't the knight to defeated the enemy instead she was chosen by the Round Table to show the goodness of her heart. Goddess Rhongomyniad becomes confused by Bedivere's identity, but Mash's reply that she know him as a Knight of the Round leaves her more confused. In response, Bedivere counters Rhongomyniad with Airgetlám, whose light Goddess Rhongomyniad recognizes yet leaves more confused about Bedivere. He then apologizes to Ritsuka for knowing the truth of the Lion King from the very beginning as Ritsuka notices his body is breaking down. Romani then reveals Bedivere to be not a Servant but a regular Human. Confirming Romani's analysis, he reveals Airgetlám is Excalibur in disguise. When Goddess Rhongmyniad finally remembers his name, Bedivere reveals he failed to return Excalibur to the lake on his third try out of fear losing his king. But when he saw she was gone upon returning to the forest, he realized his failure to return Excalibur left Artoria unable to die. With Rhongomyniad still hand, she wandered the earth and eventually became a Divine Spirit. Bedivere spent 1,500 years searching for Artoria to atone for his failure with Excalibur keeping his body alive throughout the centuries. After Bedivere thanks Ritsuka for giving another chance to meet Artoria, Goddess Rhongomyniad tells Bedivere to throw Excalibur away and return to her despite still not remembering him. Bedivere refuses and fights her together with Mash. Despite her power though, Goddess Rhongomyniad is shocked to find a mere human like Bedivere is able push her back. When asked why he still fights her despite his body breaking, Bedivere answers it's because he still remembers her smile. As she begs him not to use Excalibur, he thanks her on behalf on the Knights of the Round for saving Britain despite carrying the burden of their era alone and being ostracized. Calling her his shining star, Bedivere returns Excalibur to Goddess Rhongomyniad. Upon being returned Excalibur to her, Goddess Rhongomyniad finally remembers Bedivere, and thanks him for fulfilling her last order to him as her last and most loyal knight.

After Bedivere disappears, Rhongomyniad vanishes with Excalibur being returned, which results in the collapse of the era to cease, and Camelot to begin disappearing. With Excalibur in hand, Goddess Rhongomyniad is prepared to fight the group again, but she decides against it as the group begins to disappear. With the Grail retrieved and Rhonogmyinad gone, Romani explains the era's restoration is occurring rapidly as result to return any foreign existences to it (such as Camelot) to their original places. As the group continue to disappear, Goddess Rhongomyniad returns to her throne to Mash's confusion. Da Vinci explains to her that Goddess Rhongomyniad won't disappear like a summoned Heroic Spirit as she arrived in the era through her own power. She further reveals that with Rhongomyniad now gone, Goddess Rhongomyniad's existence will cease. Da Vinci explains that even if the group were to meet another King Arthur wielding Rhongmyniad, they will not be the same person. When Mash become sad at Bedivere's sacrifice possibly being in vain, Goddess Rhongomyniad assures her that wasn't as she has been released. She states that her existence allowed her to learn a certain truth about Solomon due to acquiring the same perspective as him. She reveals the temple which Solomon resides in is outside the proper flow of time, which only the seventh Grail can reveal its location as it's the only one Solomon personally sent into the past. Romani is confused about the seventh Singularity existing before Solomon's era as he thought Solomon left behind Grails to eventually manifest in each era he knew served as Foundations of Humanity before his death. Goddess Rhongomyniad confirms six of the Grails were indeed left behind to be found by mages descended from Solomon's bloodline to manifest as Demon Gods when the time of their awakening arrives. The seventh Grail alone was sent into the past by Solomon, which was the first step towards the Incineration of Humanity. She tells the group that as long as the era where the seventh Grail resides is left unrestored then human history will remain incineration. Thanked by Romani for the information, Goddess Rhongomyniad tells Ritsuka that she believes her motives were right as protecting humanity requires a different approach than protecting an individual. For that very reason she tells Ritsuka to follow they feel is best. She then warns them at the final Singularity lies an unimaginable evil, one that surpasses Solomon, the original sin of humanity. Goddess Rhongomyniad tells Ritsuka gather allies who will falter when faced against the Evils of Humanity. She then states there was meaning in both Bedivere's mistake and her existence before the group is forcibly rayshifted back to Chaldea. Meanwhile, outside the city, the Enforcement knights disappear, Camelot forces surrender, and Touta disappear after saying his goodbyes. Inside the city, Cursed Arm resigns himself to be eaten by Shaytan as he's unable to move. However, Shaytan is slain by Hassan, and Cursed Arm prepares to executed by him. Hassan decides to spare him though, claiming Shaytan's arm is Cursed Arm. Telling Cursed Arm he's no longer one of the Hassans, Hassan congratulates him for alone escaping the fate of the Hassans. After Hassan leaves, Cursed Arm decides to stay in era to help restore the Saracens, pledging it on his original name of Hanam. Once that task is finished, he hopes to meet and help Ritsuka again. Inside the castle, Agravain enters the throne room grievously wounded, and tells Goddess Rhongmyniad that the rebels are coming. Though he knows she would never lose against them, he also knows of her tendency to respect her opponent's ideal. Goddess Rhongomyniad tells Agravain he should be concerned about himself as she observes his wounds. Revealing he was victorious against Lancelot, Agravain is told by Goddess Rhongomyniad to approach her throne so she may at least ease his little. He replies he isn't worthy as he still needs to defeat the rebels, restore Camelot, guide the selected citizens, and build a splendid palace for her. However, when he realizes his end is near, Agravain apologizes to her for again failing to create the ideal utopia she wanted and he wanted to give her. Goddess Rhongomyniad doesn't blame him for his failure though, and she tells to rest since his single flaw is him being a workaholic. Agravain considers her concern to be nonsense since she is more of a workaholic than him.

Babylonia: The Absolute Frontline in the War Against the Demonic Beasts
Babylonia: The Absolute Frontline in the War Against the Demonic Beasts (絶対魔獣戦線), alternatively The Chain of Heaven (天の鎖), was the last of the seven primary Singularities in the Human Order Incineration Incident. Located in Mesopotamia, B.C. 2655, it's Humanity Foundation Value was A++.

Setting
The Singularity occurred in Mesopotamia in 2655 B.C. during the latter part of Gilgamesh's reign. Solomon personally sent one of his Holy Grail into the era, and pulled Tiamat from the World of the Void. When this happened, Gilgamesh, who just returned from the underworld, foresaw Uruk's destruction, and inscribed his vision in the Tablet of Destinies. Leaving the tablet in Kutha, he returned to Uruk, and told his subjects of his vision. He then took the role of a mage to protect Mesopotamia, and began to prepare its people for their impending doom. . Meanwhile, Merlin trapped Tiamat in a dream to prevent her return. However, she was able to implant the Grail into Enkidu's corpse to reanimate it for the purpose of awakening her, calling it Kingu. Kingu believe themselves to be Tiamat's child, and they are the prototype of a new humanity based on Enkidu. While searching for a way to awaken Tiamat, they eventually found Gorgon, who was summoned by the Grail's influence, in northern Mesopotamia. After they restored her Divinity, she gained the Authority Potnia Theron, which allows the creation of monsters, by synchronizing with Tiamat's consciousness. As a result of the synchronization, Gorgon is deluded into believing she is Tiamat's second coming, and decides to take revenge on humanity in her stead. However, because she isn't Tiamat, Gorgon isn't able to use Potnia Theron to create monsters by herself. Thus, she is forced to capture humans and bring them to her temple in the Cedar Forest, the Blood Fort, where they're converted into Demonic Beasts. They are then sent out to capture more humans to bring them back to the Blood Fort so more Demonic Beasts can be created. Meanwhile, Medusa is summoned in her child form in the Cedar Forest by the Grail's influence. She would keep herself sustained by feeding on the souls of the Demonic Beasts she killed.

With the appearance of Demonic Beasts in the north, the era began to turn into a Singularity. Gilgamesh ordered Babylon to be dismantled, and used to a build wall to seal off the north from the rest of Mesopotamia. The sacred temple however foresaw the era would turn into a Singularity, and decided to summon Ishtar without Gilgamesh's knowledge. While the Northern Wall was constructed, the temple matron took advantage of the era's unstable space-time to connect to other eras to summon Rin Tohsaka. As she is compatible with Ishtar, Rin is used by the temple matron to summon the goddess, and to serve as her vessel. Unbeknownst to Ishtar though, Ereshkigal is summoned when she is summoned, and killed the temple matron. She also gained control of Ishtar's vessel when the latter is asleep. . Ishtar would go on to protect the ranchers in the northeast from the Demonic Beasts. However, she would demand their jewels as compensation for protecting them while also harassing Uruk.

In the south, Quetzalcoatl and Jaguar Man are also summoned by the Grail's influence. They soon took control of Ur and Eridu where Quetzalcoatl placed her Noble Phantasm, Piedra Del Sol, at the altar of a temple she had built to increase her Divinity in Sumer. Both cities are soon surrounded by a jungle that prevents Demonic Beasts from entering. However Quetzalcoatl bans the people of Ur from leaving to get help elsewhere, and those who break that rule will be killed by the jungle. She also has them send one man a day to Eridu under the pretense that they're sacrifices to satisfy her. In reality though, she is training the men of Ur to be part of her army.

Eventually, Kingu convinces Gorgon, Quetzalcoatl, and Ereshkigal to become a three-joint alliance that'll become known as the Three Goddess Alliance. Each member is bound by a rule that prevents them from taking hostile action against each other, which also includes revealing their True Names. Any violation of the rule results in the goddess who broke it in being destroyed. . While the Alliance's main goal is humanity's extinction, they're also competing with each other to see who can destroy Uruk and obtain the Greater Grail of Uruk first. Each member use their own methods to complete their supposedly common goal; Gorgon would use her Demonic Beasts; Quetzalcoatl would personally kill one hundred humans a day; Ereshkigal would use her gallû spirits to take people's souls, resulting in the death of Kutha's population. . However, Quetzalcoatl and Ereshkigal have their own reasons that they joined the Alliance that don't align with it's goal unlike Gorgon. Quetzalcoatl joined to stop the other members by getting to the Grail of Uruk first, and she wanted humanity to truly hate Gorgon so they'll fight with all their strength. Ereshkigal joined the Alliance to protect as many souls as she can in the underworld out of her love for humans. The Alliance would ho on to destroy cities, forcing many to flee to Uruk.

After the era became a Singularity, Gilgamesh summoned Merlin whose imprisonment in Avalon normally makes him impossible to summoned as a Servant. However since era exist before his death, he is technically dead, and thus able to summoned with Gilgamesh's tremendous magical energy. The appearance of the Beasts was also major factor in his manifestation alongside King Hassan. After summoning Merlin, Gilgamesh summons Ushiwakmaru, Musashibou Benkei, Leonidas, Amakusa Shirou, Fuuma Kotarou, Ibaraki-douji, and Tomeo Gozen, incarnating them through his own magical energy. Leonidas commands the efforts against the Demonic Beasts, and trains both the soldiers of Uruk and the Northern Wall to be a self-sufficient force. The other Servants summoned by Gilgamesh also help defend Uruk, though Ibaraki would eventually defect. Shirou and Kotarou would perish alongside the scouting parties Gilgamesh sent to investigate the jungle surrounding Ur and Eridu. . Tomoe would die killing Girtablilu, the general of the Demonic Beasts. Merlin would eventually encounter Medusa in the Cedar Forest, and tricked her into a contract that sealed her Divinity until she's truly ready to face Gorgon. Half a year later before Chaldea arrived, Uruk became a fortress city, and its people were able to survive for half a year thanks to their resolve and Gilgamesh's preparations. By the time Chaldea arrives, the Alliance has eliminated roughly 80% of the population, and conquered 60% of Mesopotamia.

History
Unlike their previous rayshifts, Ritsuka Fujimaru and Mash Kyrielight arrive in the era falling from the sky. Fortunately, Ritsuka grabs onto Mash, and she deploys Lord Camelot to soften their landing. Romani Archaman answers the reason they were rayshifted into mid-air was because it was tampered with. He explains the coordinates of the Rayshift were set for the largest city of the era, but they shifted after the Rayshift was established. Ritsuka and Romani disagree with Mash's speculation that Solomon is responsible, believing some power in the city is responsible. Leonardo da Vinci explains that tampering of the Rayshift was caused a defensive Bounded Field surrounding. Concerned about Uruk given the barrier, Romani orders Ritsuka and Mash to reassess the situation there. He is unable to give them coordinates though, as the era's mana concentration is overwhelming Chaldea's instruments. Using the video feed, he confirms the Band of Light in the sky, and the pair are currently in a ruined town. Give the high mana concentration, he check Ritsuka's condition when Mash detects an odd magical energy signature approaching. Romani confirms it as an hostile, apologizing it took longer to confirm since the signature pattern is new. Slaying the Demonic Beasts with minor injuries, Mash describes them as if looking to be from a completely different ecosystem. She continues that unlike ones who disappeared from the world when the Age of Gods concluded, these Demonic Beasts seemed otherworldly. Romani believes they differ from the usual Demonic Beasts in the Age of Gods, but they don't match any data on those from the era. Mash tells him the Demonic Beasts weren't trying to kill her and Ritsuka out of a bestial instinct to feed, but solely to kill them. Romani realizes the Demonic Beasts were responsible for the ruins, so he orders to leave the pair immediately. Suddenly, a girl crash lands on Ritsuka, and she almost immediately prepares to fight. Mash explains to her that she and Ritsuka only arrived in the era less than an hour age, and that they're from Chaldea, sent to correct the Singularity. The girl decides to accept her words, believing Mash and Ritsuka to be just ignorant barbarians. Romani introduces everyone, and he asks for her name. The girl refuses to give her name, citing Romani to be unworthy. She tells him and Ritsuka to forget what happened earlier, saying she'll spare Ritsuka's life if they do. Though refuses to tell them about the era, the girl asks them if they saw something precious on the ground. They try to ask what is, but she refuses to say. Suddenly though, another pack of Demonic Beasts attacks, and the girl joins the pair in the fight. After they're slain, the girl tells Ritsuka to either return to Chaldea or die if they struggle against the Demonic Beasts. She then leaves saying she doesn't intend to help the weak. Romani orders Ritsuka and Mash to head east since there are fewer Demonic Beasts that way. The pair breakthrough another pack of Demonic Beasts, but more of them continue to appear. A person then suddenly appears and easily wipes out a large number of Demonic Beasts. They introduce themselves as Enkidu, and helps Ritsuka and Mash to kill the remaining Demonic Beasts. Enkidu warns the pair they need to leave quickly, as the scent of blood will attract more Demonic Beasts. After explaining their origins and nature, Enkidu confirms to Romani that they know about the Holy Grail, the Singularities, and the Incineration of Humanity from the temple matron of Uruk's prophecy. It is because of the matron's prophecy that they came to help Ritsuka and Mash. They tell Mash that the people of the era are actively fighting against their destruction. Enkidu then guides the pair out of town to Uruk by taking a longer route to avoid Demonic Beasts.

Slaying Demonic Beasts along the way, the group eventually get past the ruins. Romani finds odd it though they're heading north, instead of south where Uruk is. Enkidu explains they would a different goddess' territory if they headed down south. Realizes the other don't understand what they meant, Enkidu explains roughly 80% of Mesopotamia's population have been killed. They continue that the Three Goddess Alliance descended on the era, and claimed 60% of Mesopotamia's territories. After Mash tells them about the Divine Spirit Servants in Chaldea, Enkidu says the goddesses of the Alliance possess Spirit Origins are equal to those of true gods, unlike the Divine Spirits at Chaldea. They then state the Demonic Beasts are like the children of one of the goddesses. They explain the Three Goddess Alliance is, as the name suggests, an alliance of three goddesses, but the only their objective is clear: humanity's extinction. Each of the three goddesses are each using their own methods to destroy Mesopotamia. The greatest of the three, the "Goddess of Demonic Beasts" from Greece, is responsible for the Demonic Beasts. Reaching an plateau, Enkidu shows Ritsuka and Mash the massive horde of Demonic Beasts attacking the Northern Wall, built by dismantling Babylonia. Mash confirms to Romani that soldiers outside the wall are holding their own against the Demonic Beasts. Enkidu says the soldiers have been holding the wall for six months, fighting against the Demonic Beasts day and night. The humans utilize their army precisely, change shifts seamlessly, train new soldiers during combat, and have their wounded rest and heal. Citing it as the ultimate in point defense, Enkidu says the humans should hold the front for another month. Romani then orders Ritsuka to request an audience with Uruk's king, explain their objective, and find and recover the Grail. Seeing they were attacked by Demonic Beasts earlier, Enkidu takes Ritsuka and Mash into the Cedar Forest.

Inside the Cedar Forest, Ritsuka, Mash, and Romani find it strange that Enkidu is leading them further from Uruk. Enkidu explains they're heading towards a wharf, where they'll take a boat downstream. The group then meet a man accompanied by a young girl who has been wandering for three day straight. Ritsuka and Mash introduce themselves, but when Enkidu is introduced, the man points out Gilgamesh recently returned from his quest for the herb of immortality. The group realize the Enkidu they've been travelling with is a fake. The fake Enkidu realizing their ruse has been discovered, goes to kill Ritsuka and Mash. With help of the young girl named Ana, Ritsuka and Mash fight the fake Enkidu. In the midst of their fight, the man traps them in an illusion of the forest. In reality, Ana lures the fake Enkidu out the forest. After cancelling the illusion, the man reveals the fake Enkidu is working directly for Solomon. He says the fake Enkidu has been calling themselves Enkidu as they wipe out entire cities. When Ana returns from luring the fake Enkidu, she casually reveals the man to be Merlin. Merlin introduces himself and Ana, saying they're both Servants. Romani interrupts Merlin to ask him how he can be a Servant since he shouldn't die until the world ends. Mash explains Merlin's role as King Arthur's adviser and court mage, and how he escaped to Avalon and trapped himself in a tower to repent for his sins. Since both Avalon and the tower exist outside of time, Merlin cannot die and become a Heroic Spirit until the world ends. Merlin confirms Da Vinci's speculation that he had been secretly using a replenishing method similar to Rayshift to kindle Chaldea's reactor, The Fire of Prometheus. Given Enkidu's betrayal though, Da Vinci demands to know the reason and method that Merlin can be a Heroic Spirit. Merlin doesn't reveal the exact the reason, but it is related to the Singularity. He then explains that since Singularity manifested in an age before his birth, he is technically dead. Using that fact, he made himself into a Servant, and part of it was that he was summoned by a strong summoner. He reveals he is now serving as the court mage of said summoner, and Ana is a Rogue Servant summoned by the Grail's influence. He met her two days ago while lost in a forest, and they made a contract to support their goals; Ana refutes he tricked her. After joining Ritsuka and Mash, he helps them to slay a pack of wyverns. The group head to Uruk after Ritsuka convinces her with come with them.

A day after leaving the forest, the group will reach Uruk in another day. Merlin explains Northern Mesopotamia belongs to the Demonic Beasts, while the south has become a mysterious jungle that no one returns from. Romani states the Alliance has devastated many cities, causing many people to flee to Uruk for safety. Merlin warns that it is uncertain what happen to humanity if the Demonic Beasts destroy the first dynasty of Sumer with Uruk and the blueprint of city-states with it. He also says Egypt's first dynasty was flourishing during the period, but they alone cannot preserve the Foundation of Humanity. He states the group need to first, recover the Grail Solomon sent to the era, and then defeat the Alliance if possible. He reveals he knows the True Name of the one of the goddesses; the goddess controlling the Demonic Beasts is up north; another goddess resides in the jungles in the south; also another goddess is soaring through the sky. Merlin cites the northern goddess as the biggest threat, but the soaring goddess is possibly more troublesome than the northern goddess. He then confirms to Romani that Gilgamesh is currently ruling Uruk. As the others discuss Gilgamesh's legend, Ana warns them of approaching Demonic Beasts. After slaying the beasts, the group eventually reach the gates of Uruk. A soldier at the gate demands to which city Ritsuka and Mash from. Merlin answers they're from Girsu, and wants to evacute them into Uruk. Seeing Merlin carries Siduri's seal, the soldier allows the group to pass. After explaining how the city handles refugees, he welcomes the group to Uruk. After Ana is given some candy, the group finally enter Uruk to find it bustling.

Heading straight to the ziggurat, the group see Gilgamesh directing the efforts against the Demonic Beasts, as various soldiers and priests report to him. Merlin forcibly bring Ritsuka to him, and reports he didn't return with the. Siduri chastises him for his failure, and asks to know who Ritsuka and Mash are. Gilgamesh dismisses her concern, having decided to fight Ritsuka and Mash. He also orders Merlin to not interfere. Asked by Merlin, Ana assist the pair in their fight. Halfway through the battle, Gilgamesh begins to hold back. After the battle ends, he decides Ritsuka and Mash aren't worth his time, and orders them to leave. Siduri wonders if the pair are the strangers that Gilgamesh spoke of. Gilgamesh believes they probably are since Merlin brought them, but says it far too soon. Merlin reveals to Ritsuka and Mash that he didn't tell Gilgamesh anything about Servants or Chaldea's mission. Romani tells Ritsuka to try to explain things to Gilgamesh, but Gilgamesh says that isn't necessary. He reveals he knows about Heroic Spirit summoning, and aware he will become a Heroic Spirit. Mash tell him they need to quickly find the Grail to prevent the Singularity from destroying humanity. Gilgamesh reveals he already possesses the Grail, but outright refuses to give to Chaldea. Ritsuka asks if he'll give it in exchange for defeating the Alliance. Gilgamesh laughs them off, and then states he doesn't help from Chaldea. A soldier then brings a message from the observation post near the that Ishtar, a member of the Alliance, is speeding towards Uruk. Suddenly, Ishtar, the girl Ritsuka and Mash met when they arrived in the era, bursts down through the roof. She decides to kill Gilgamesh for insulting her, and Ritsuka to stop any rumors of their first encounter from coming out. Amused by this, Gilgamesh allows the group to fight alongside him. After the fight, Ishtar decides to destroy the ziggurart allow with Gilgamesh, but she stops when she sees Ana. After Ishtar leaves, Gilgamesh and Siduri return to work. Merlin suggest to the others they find a place for the night, and talk to Gilgamesh tomorrow. Gilgamesh however asserts he doesn't need their help, stating any diaster caused in the era will be solved by its people. He states Chaldea will be called if they needed, and reveals he summoned Merlin. Merlin confirms such, and explains how Gilgamesh became a mage to protect Mesopotamia. He also explains summoning is easier in the Age of Gods than in the modern age when Gilgamesh states he performs real Heroic Spirit summoning unlike Chaldea's Fate system. Nonetheless he commends Chaldea for developing the system, and for removing the six previous Singularities. Regardless of their achievements though, he again assert that they're needed. He then gives Siduri charge of the group after saying they should work hard if they want to assist him. Outside the ziggurat, Siduri introduces herself, and suggests the group help various jobs in Uruk to prove their worth to Gilgamesh. Stating she'll make the proper job arrangements, she leads the group to lodgings. Before that though, Mash asks her why she help them, to which Siduri replies it was Gilgamesh's command.

Siduri leads the group their new lodgings, an old tavern, which Mash dubs the Chaldean Embassy. Merlin goes to pick his room on the second floor; Ana follows him to keep him making mischief. After half a day of cleaning, the group eats with Siduri and Gilgamesh's Servants: Ushiwakamaru, Musashibou Benkei, and Leonidas. Romani explain Ushiwakamaru and Benkei slay the Demonic Beasts around Uruk, and Leonidas commands the soldiers against the Demonic Beasts. Ushiwakamaru says that she and the others were summoned by Gilgamesh, they know nothing about Chaldea. She warns they would side with Gilgamesh against Chaldea if ever forced to choose. But she agrees their mission to save the era and defend Uruk is the same as Chaldea's. Romani asks if Gilgamesh is one only providing magical energy to his Servants. After confirming such, Benkei explains that after Gilgamesh summoned Merlin, he summoned seven Heroic Spirits. However of the seven summoned, only four are remaining. He continues that Gilgamesh formed their Spirit Origins with his own magical energy during the summoning. Essentially incarnated, they can eat and sleep like humans, and generate their own magical energy. Merlin explains how Gilgamesh summoned seven more Heroic Spirits despite being nearly drained by summoning him. He also says the reason Gilgamesh isn't fighting on the front lines is partially because he hasn't yet recovered his magical energy. Leondias states how Gilgamesh foresaw a future where Uruk was destroyed and swallowed into an abyss when the Demonic Beasts destroyed the northern cities and Kutha vanished overnight. After the era became a Singularity, he summoned seven Heroic Spirits, and half a year later, turned Uruk into a fortress city. The people grow crops, train soldiers, and build structures all while fighting against an unknown enemy. When Ritsuka mentions the Fake Enkidu, Mash wonder if Gilgamesh knows about them. Merlin confirms he does, but since he never met them personally since he never leaves the ziggurat. Merlin tells Ritsuka to get some rest for tomorrow. He explains he has something he's investigating, so Ritsuka and Mash will need to get help from Siduri and the other Servants while he's gone. After Merlin leaves, Ritsuka and Mash go to sleep.

Over the next several days, Ritsuka, Mash, and Ana are tasked by Siduri with various tasks. The first is to help a rancher out in Uruk's outskirts shear his sleep, but they ended up defending him from Demonic Beasts. After slaying the Demonic Beasts, the group bring the remaining sheep to the Sacred Temple.

The second task calls for the group, joined by Ushiwakamaru and Benkei, to investigate into the possible affair of the armorer's wife, while Ana helps with the flower shop. The investigation leads the group with discovering and stopping a plot by an underground species, one of whom is the armorer's wife, to invade the surface. Afterwards, Ushiwakamaru explains how Uruk is under constant threat from the Demonics Beast from the north, the jungle in the south, and Ishtar in the northeast. While Leonidas commands the efforts agains the Demonic Beasts, Ishtar is unpredictable, and nothing is yet known about the jungle. Benkei explains how Gilgamesh previously sent scouting parties to investigate the jungle, but none of them ever returned. When Romani mentions the Alliance is after Gilgamesh's grail, Ushiwakamaru wonders if they want to use it to re-create the world in their image after destroying Uruk. However, Romani notices Ushiwakamaru said Gilgamesh called his Grail, The Greater Grail of Uruk. He then confirms Ritsuka's speculation that the Grail held by Gilgamesh is his own, and not Solomon's. Now realizing the Grail they seek isn't in Uruk, Ritsuka wonders if one of Alliance members has it.

The next day, the group is tasked with performing a mock battle with Leonidas and a hundred of his trainees. After the battle, Leondias gives a lecture to soldiers, which Mash quickly joins. As the lecture continues, Ana reveals she suddenly woke up in the Cedar Forest in her current body, and with no knowledge about being a Servant. She then went on to kill several Demonic Beasts, and used their souls to maintain herself. She refuses Ritsuka's offer to contract with them, stating she is only with them because of her hostilities with the Alliance.

After twenty days, Ritsuka and Mash help Ana with the problem she is investigated. Taken to a cave underneath Uruk, the group defeat the spirits residing there. After they return, Ana explains the spirits were likely responsible for people falling into an eternal slumber by taking their souls. She continues the soul can be returned to its body as long as its preserved, but the body will perish if the soul is destroyed before reaching. After Mash goes with Ana to report to Siduri, Ritsuka meets a seemingly crippled old man. They give the old man some bread, but they're stopped by him. He warns Ritsuka that pity can be at times itself a crime if void of purpose, as it is with shame. He commends Ritsuka for giving what he needed, instead of just money, and introduces himself as. Ziusudra then gives Ritsuka three warnings; Empathize not with the hateful; Celebrate not with the joyous one; extol not the pained one.

Ritsuka has dream where a voice speaks of mankind's sins, evils that only affect them. The oldest of these is the Original Sin II, the sin of parting from ■, and leaving paraside. The voice continues that life was born from, the goddess of the beginning, who to humans is the sea itself. It claims the roaring of the waves became a voice to expose mankind's sins. It tries to say the name of this voice, but it begins to cry ending the dream.

Recognizing the group's recent achievements, Gilgamesh gives them a task, which further will come from Merlin. Outside the ziggurat, Merlin explains they will be heading to in the south to investigate the jungle. Ushiwakamaru commends the group for finally being entrusted with an order by Gilgamesh. Before Benkei departs to help Leonidas, he and Ushiwakamaru do a praticle battle with group to congratulate them. After the battle, Ushiwakamaru and Benkei commend the group for their skills. He warns them though that two Heroic Spirits summoned by Gilgamesh, Amakusa Shirou and Fuuma Kotarou, also never returned from the jungle. He states how Ibaraki-douji defected from Uruk and fled somewthere, while Tomoe Gozen perished killing, the general of the Demonic Beasts. After thanking Ushiwakamaru and Benkei, the group leave Uruk.

As the group fight through Demonic Beasts on their way to Ur, Ana is concerned about the increasing number of Demonic Beasts from the north. Merlin is worried people will start claiming the Goddess of Demonic Beasts is the same as Tiamat. After explaining Tiamat's legend, Romani explain how she possessed an Authority called Potnia Theron, which allows the creation of infinite amount of monsters, provided they have the resources. Based on the number of Demonic Beasts, he believes the northern goddess possesses the same Authority. Merlin agree that due to that people of Uruk see her as Tiamat, especially since the Demonic Beasts are all Tiamat's offspring. Since the northern goddess is the great threat to Uruk, Romani wonders if Gilgamesh has a plan, especially if she is Tiamat. Merlin tells him to focus on the south for now, and the group will be at Ur once they cross the.

Entering the jungle, the group complain about its heat, density, and the abundance of critters; Mash compares it to those when dinosaurs existed. Merlin states its ether is dense than Britain, and that it's on par with a Reality Marble. Romani is unable to get any readings since Chaldea's instruments are unstable. Da Vinci compares the jungle to Egypt, calling it a different world, or its mythological system is different. She tells the group to rely on their sense, especially sight and smell, to navigate the jungle, as she's unable to use Sheba to discern anything there. Mash says the group that Ur is a kilometer south, and they'll arrive there in twenty minutes. Suddenly, an unseen person mocks the group, as they move at high speeds above the trees. The person show themselves to be a strange woman wearing tiger pajamas when she fell down. She introduces herself as Jaguar Man, and the group fight her. After the fight ends, Jaguar Man retreats, but they decide not to pursue since too powerful for them. Instead they continue onto Ur.

Entering Ur, Merlin tells a woman there that he and the others were ordered by Gilgamesh to investigate Ur. The woman says Ur is safe, as the surrounding jungle prevents the Demonic Beasts from entering. Merlin asks if she thought isolating themselves in Ur was the best course of action. the woman answers that they tried to send help to Uruk, but it was violation of the jungle goddess' rules. Merlin realizes the people of Ur are safe, but they're banned from leaving; anyone coming to help, or leaving to help, is killed by the jungle. He then asks the woman how many have been sacrifice, guessing it's one a day. The woman tries to deny it, but Merlin points out the lack of males in the city. Since Ur isn't at war, he deduces the males were sacrificed. The woman says the sacrifices were necessary as everyone agreed, and they must offer one a day to to satisfy the goddess. Due to Mash's rebuking the woman, the rest of the people retreat into their home out of guilt. Jaguar Warrior then appears and fights the group so they can take them outside. However, she is far too fast and powerful for them, as Merlin realizes she is a Divine Spirit. He implores the others to retreat since they completed their investigation of Ur. Jaguar Man catches up to the group several times as they escaped the jungle, but Ana drove her off each time. Upon returning to Uruk, they report their finding to Gilgamesh. He asks Merlin if he could see Eridu from Ur, asking if the axe is still there. Merlin answer he couldn't see Eridu due to the jungle's density, but he did sense a powerful divinity, so he assumes the axe is still in Eridu.

The next morning, Gilgamesh enters the Chaldean Embassy to everyone's surprise. He orders them to look into Uruk's water supply, which south of the city, towards the Persian Gulf. An observatory has been constructed, with ten days' worth of jars made to automatically gather seawater. The group's assignment is to deliver the empty jars in the wagon and return with the jars at the observatory. Gilgamesh says the route to the Persian Gulf is the only area the Alliance hasn't attacked. He continues Merlin and Ana will not be going with Ritsuka and Mash, as he only had two travel permits to the gulf.

Joined by Gilgamesh, Ritsuka and Mash travel to the Persian Gulf. After destroying stone colossi, the group arrive at the observatory. While Gilgamesh checks something at the observatory, Ritsuka and Mash exchange the jars. Since Gilgamesh won't be back in twenty minutes the pair take the time to rest. However, Mash sees something in the sky travelling at 500 kph with mana concentration of the Age of the Gods towards her. She blocks it with her shield, and it turns out to be the fake Enkidu. The fake Enkidu goes to kill Ritsuka and Mash since they believe them to be alone, and Ishtar isn't around to protect the gulf. The pair struggle against the fake Enkidu, but Gilgamesh arrives to counter their attacks. At first, Gilgamesh treats the fake Enkidu similar to the original, but Mash tells him they're an impostor. He then points they may be stronger than the original, and surmises they were gifted with an immensely powerful magical reactor core by the Alliance. The fake Enkidu, strained by Gilgamesh's presence, retreats towards norther Uruk, saying they'll end the world along with him. The fake Enkidu is strained by Gilgamesh's presence. and they retreat towards northern Uruk, saying they'll end the world along with him. Since he's accomplished what he needed to do, Gilgamesh returns to Uruk with Ritsuka and Mash. Meanwhile, the fake Enkidu questions why they retreated at the sight of Gilgamesh. Though they want to speak with him, they nonetheless vow to kill him for Mother.

The next day at the ziggurat, Gilgamesh orders Ritsuka, Mash, and Merlin to go to and retrieve the Tablet of Destinies. He explains he foresaw the future in Kutha when he was travelling back to Uruk from the underworld. He recorded what he foresaw on a clay tablet, and left it at Kutha. However, he doesn't remember what future he recorded as he did it subconsciously. He also tells the group to gather information from the few ranches on the way to Kutha about Ishtar, who's been blamed for damaging the ranches. When Ritsuka asks if Kutha is under Ishtar's influence, Siduri answers that Ishtar controls the skies above northeastern Uruk. After Gilgamesh permits them to leave through Uruk's north, the group hurry to the embassy. Mash tells Ana will be coming with her and the others to help retrieve the Tablet of Destinies from Kutha. She explains the trip will take two days, and they have one day to search the city. As the group get ready, Ushiwakamaru warns them that while Kutha is under Ishtar's control, it is also near the Goddess of Demonic Beasts' territory. She implores to be careful on their journey as they'll likely encounter many powerful Demonic Beasts. Outside the embassy, Merlin tells the others that Kutha's populace disappeared when the Alliance was formed. An expedition party sent there saw that none of the corpses had wounds on them.

As they travel to Kutha, the group gather testimonies from ranchers about Ishtar. From their testimonies the group learn Ishtar has been attacking and extorting the ranchers. Responding to the other's confusion on her greed, Merlin reveals she isn't the normal Ishtar. He explains when the Demonic Beasts appeared in the north, the Sacred Temple tried to summon Ishtar without Gilgamesh's knowledge. Foreseeing the era would turn into a Singularity, they took advantage of the instability of space-time. As Gilgamesh built the Northern Wall, the temple matron summoned a human compatible with Ishtar to summon her. Merlin points Mesopotamian gods are blond while humans have black hair, therefore the current Ishtar is the girl serving as her vessel. Ana alerts the others to approaching Demonic Beasts, so they slay them before moving on to Kutha.

When the group arrive in Kutha, Romani reports none of the Demonic Beasts aren't trying to enter the city. Merlin says the situation in the city is fundamentally different from other cities, something he and Gilgamesh had overlooked. He feels Gilgamesh left the Tablet in the city for a reason. He then tells the group to split up to search for the Tablet; Mash to the east; him to the north; Ana to the west; Ritsuka to the south. Mash refuses to leave Ritsuka alone, but Merlin assures her they'll be safe. After ten minutes of searching, Ritsuka suddenly find themselves trapped in a cage underground surrounded by gallû spirits. Ziusudra appears to drive them off, and explains Ritsuka is in the underworld, which lies underneath Kutha. He then expels Ritsuka back to the living world with a message to give Merlin: "All is well in the underworld". When they return, Ritsuka is found by the others, returning from their search, sitting on the tablet. Ritsuka tells Merlin that they were underground, and they were rescued by Ziusudra. Merlin asks Romani for his records on Ritsuka, but Romani says he has no record for the past few minutes, as if Ritsuka was dead. Romani then explains to Ritsuka that Ziusudra is the name of the survivor of the flood that eradicated mankind, the one who foresaw the end of the world and became the Guardian of the Abyss. He doesn't believe the Ziusudra Ritsuka met isn't the actual one, but considers the possibility he's real with Ishtar and Enkidu's appearances. Merlin wonders if someone is taking the role of Ziusudra, though none claim that name on a whim. Contemplating Ziusudra's message, he understands the Queen of Kur has also materializes. He realizes the true identity of three goddesses he saw through his clairvoyance. But Romani interrupts him to warn everyone that Ishtar is approaching. Ishtar attacks the group for questioning the ranchers about her activities. She claims she never extorted the ranchers, but she did demand compensation for protecting them. The group then fight her, but she flies away whenever they gain the upper hand. Ishtar suddenly gets drowsy, which Ana takes advantage of to jump up and knock her down. The impact knocks Ishtar unconscious, so the group tie her up.

Ishtar wakes up later that night, and becomes terrified by Fou, recognizing him as a Beast of Calamity. Merlin explains to her the rope is woven from lapis lazuli and the hides of Demonic Beasts, which even she'll need a moment to break, plenty of time for Ana to kill her. Mash asks Ishtar for the reason the goddesses attack Uruk, for their True Names, and who summoned her. Ishtar answers the reason the goddesses is attacking Uruk is because they wish to control the world. She wants to rule humans while the northern goddess want to rule the world. The goddesses are thus competing with each other to see who can destroy Uruk first and obtain Gilgamesh's Grail. Once one of the goddesses obtains the Grail to control the world, the other two will either leave, or remain to serve as subservient deities. Ritsuka asks Ishtar for the other goddesses' True Names, but she refuses to do so since it would violated the alliance's pact to not attack each other. She confirms she was summoned by the Sacred Temple, but the northern and southern goddesses were summoned by the Grail. Suddenly the group are surrounded by skeletons from all over the city, larger than the population of Kutha. They decide to retreat from Kutha before they're overwhelmed by the skeleton since they have the Tablet. As they breakthrough the skeletons, Merlin realizes the skeletons aren't just Kutha's population, but also those who died in the past. The overwhelming amount of undead blocks the group's path out of the city. Fortunately Ishtar, freed by Ritsuka earlier, destroys a large number of the undead, then flies off to the northeast. The group take this chance to finally escape Kutha.

The group return to Uruk, and report what happened in Kutha to Gilgamesh. Gilgamesh tells them of Nippur, whose population has survived by isolated themselves in its wall while under constant siege from Demonic Beasts. He has evacuated the citizens in between the beasts' attack cycles, but now their supplies are depleted. Thus he decides any survivors of Nippur need to be evacuated immediately. He tells the group to use the break in the beasts' seven day attack cycle to lead Nippur's survivors to the Northern Wall. He then tells Ritsuka to read the Tablet since they're the ones who obtained. Ritsuka says they can't read it, but Gilgamesh tells them they only need to lay their hands on the Tablet and say: "Ur na-nam, ur na-nam. Dur-an-ki, gir-edin." Ritsuka follows Gilgamesh's instructions, and granted a vision.

A voice in the vision speaks of a king who ignored the world's suffering while smiling. Unable to forgive him, it then speaks of how the history of mankind is a cycle of suffering. The voice pities humans as imperfect beings who live in their contradictions, but it forgives them if they're commoners. However, an almighty king with the power and means to set humanity's imperfectness right is a different matter. The voice speaks of a king with eyes that could see into the past and the future. The king also saw the world's suffering but he merely laughed despite his enlightenment. Unable to forgive the king for ignoring mankind's suffering, the voice inscribed their message, so future generations would know their rage and follow in their footsteps. It instructs its followers to construct a temple and build a band of light, stating they're all resources and time to destroy this king and forget his indifference. It then reveals Solomon resides in the final Singularity, a plane named after him.

After Ritsuka returns from the vision, Gilgamesh reveals it is what he foresaw after returning from the Abyss, and it's one of few clues to finding Solomon's precise location. The group then proceed to leave for Nippur.

The group arrive at Northern Wall to find it just as bustling as Uruk, but Demonic Beasts able to run up its walls soon attack. After slaying the beasts, they are greeted by Leonidas, Ushiwakamaru, and Benkei. Leonidas takes them to the Dingr Artillery platform, where he explains how the soldier use Gilgamesh's treasures to defend the Northern Wall. He then tells the group how he and the others lead Nippur's citizens to the Northern Wall every night. However last night the Demonic Beasts began to patrol the outskirts of Nippur, likely due to being commanded by Girtablilu's replacement. As they can't delay the rescue mission since Nippur's citizens are starving, Leonidas decide to use a diversionary tactic. While Ushiwakamaru and Benkei's unit head towards Nippur from the east to distract the Demonic Beasts, Ritsuka's group will enter the city from the west. Once inside the group will open the gate and lead the citizens out. Leonidas states they'll launch their operation tomorrow later in the evening.

Later that night Merlin expresses his concerns about tomorrow's operation while reinforcing the walls with his flowers. He then tells Ana that its wise not enter the Cedar Forest since there's no way to clear that temple. Ana wonders if she should tell the others about her situation, but Merlin tells her that may freak Ritsuka out. He points out Ana fears the others will fear and hate her when they find out her true identity as a divine being. He continues that even though he and Ana are inhuman they don't need to be mankind's enemy. He explains to Ana that he doesn't like individual humans only the patterns they weave, and trying to justify his own actions resulted him in imprisoning himself. He tells her that Ritsuka is fine without knowing her True Name, which would only reveal the name of the enemy not help them fight it. He calls her a vital point the Goddess of Demonic Beasts didn't expect, and tells to watch for the instant she'll need to throw away everything. However he convinces her to escape the situation alive while tricking her enemy.

The next day, Leonidas goes over the rescue operation. There are 200 civilians left in Nippur, the majority of whom couldn't previously be evacuated: women, the elderly, and the wounded. Leondias understands though they won't leave unless their safety is guaranteed. He and the group will protect and escort the guide, a former citizen of Nippur, to its western gate and persuade the guards to open it. Leonidas' soldiers will then the citizens lead westward to the Northern Wall while the group slay any Demonic Beasts that Ushiwakamaru and Benkei fail to distract. However he hasn't heard from the messengers used to maintain contact with Nippur for the past few days. Therefore he implores Ritsuka to withdraw immediately if they sense grave danger.

As Ushiwakamaru and Benkei fight the Demonic Beasts, the group arrive in Nippur. However they're confronted by the fake Enkidu who reveals they took the citizens to the Demonic Beasts' lair last night. They further reveal the Demonic Beasts aren't trying to kill humans, but instead taking them and using them as raw materials to create more beasts. After the group slay some Demonic Beasts, the fake Enkidu attacks Ana since she's their main target. Merlin implores Fou to heal Ana, but Fou instead teleport her and himself away. Suddenly Tiamat emerges from underground, and kills the soldiers with a single swing of her tail. She introduces herself to the group as the leader of the alliance. While they're glad to see her awake, the fake Enkidu reminds her she was supposed to rest until the Day of Rebirth. Tiamat answers she wanted to see what the fake Enkidu was doing, but she doesn't the group even worth killing. However she decides to eat them, and petrifies them with her scowl. They're unable to break free, and Romani instructs them to retreat back to the Northern Wall. However Tiamat blocks their way, so they forced to fight her. Unfortunately she regenerates too quickly for the group to actually wound her. Mash thinks its because of her Authority, but Merlin reveals it's due to her possessing Solomon's Grail. Tiamat confirms she has the Grail, but claims she is using her own power to regenerate. Ushiwakamaru then arrives to hold her back while the group retreat. However Tiamat overwhelms and breaks through Nippur's walls to pursue the group. Merlin instructs Ritsuka and Mash to run away, revealing he'll temporarily return to the world of dreams if he's killed. However Titamat uses her Mystic Eyes of Petrification, so Merlin implores the others to defend him. Ritsuka and Mash are unable to defeat her, but Leonidas arrives and uses Thermopylae Enomotia to defend them. While he was able to defend against Tiamat's heat way, he couldn't avert its petrifying effects. Before he completely turns to stone thought, he reveals the so-called Tiamat to be Gorgon/. Gorgon then prepares to advance to toward Uruk with the Demonic Beasts to destroy it. She is stopped however when the fake Enkidu reminds her to wait for the birth of 100,000 Demonic Beasts in the Blood Fort before destroying Uruk. Gorgon decides to return to the Blood Fort, but warns she'll return to destroy Uruk in ten days. After she leaves, the fake Enkidu reveals they're the prototype of a new generation of humanity to replace the humans that abandoned Tiamat. They then reveal themselves to be Kingu, though not the original instead a new human designed after Enkidu. Kingu states they're the beginning of a new humanity who'll continue the old humanity's history once they're eradicated. After Kingu leaves, Ritsuka and Mash return to the Northern Wall. There Benkei decides to abandon the Northern Wall since he blames himself for Ushiwakamura's supposed death, and head towards the ruins of Nippur. Yet despite Leonidas' death, the soldiers of the Northern Wall continue their tasks as he had instructed. Merlin decides to regroup with Ana and Fou, then report back to Gilgamesh.

Meanwhile Ushiwakamaru is revealed to be alive, imprisoned in the Blood Fort. She is then confronted by Kingu who reveals they use the temple to turn humans into Demonic Beasts. Kingu prepares to turn Ushiwakamaru into one, but she asks them why they let the children escape. They explain the children aren't a threat unlike the soldiers. Ushiwakamaru however counters Kingu saved a child earlier because they cried out for help. Kingu then decides to take her to Tiamat, whose Authority is the sea of life. It is a black mud that corrupts any human including Servants into becoming children of Tiamat. It is also called the Primordial life, the sea of chaos, the mud of the Holy Grail by mage, and the Chaos Tide by Solomon.

Returning to Uruk, the group report to Gilgamesh on transpired the previous day. In answer to Gilgamesh's concerns, Merlin ponders if Gorgon is the Singularity because of Solomon's Grail or another reason. Regardless of the reason, her former appearance and power were restored by the Grail. Merlin points out though none of Gorgon's legends depict as a mother of monsters, therefore she was granted Potnia Theron by the Grail. Mash then tells Gilgamesh that Gorgon only considers the other goddesses threats. This prompts Gilgamesh to conceive a plan to have the group to persuade Ishtar into contracting with Ritsuka, so he can use her Gugalanna.

On Gilgamesh's orders, the group travel to Mt. Ebih where Ishtar built herself a temple. After slaying some Demonic Beasts, they eventually reach the mountain. As they travel up the path to the summit, they're fight demonic statues placed by Ishtar to guard the mountain. After destroying them, the group soon make it to Ishtar's temple. However, Ishtar refuses to talk and attacks them. As the fight progresses, the group stop her to bribe with the gems Gilgamesh provided them to ally with them. Ritsuka adds that she'll also receive 25% of Gilgamesh's treasury. Romani eventually convinces her by saying if humanity is incinerated then they will be no one to admire her beauty. After making a temporary contract with Ritsuka, Ishtar leaves her temple with the rest. She explains to the group that the temple matron was able to summon her vessel from another era due to the era being connected with other eras as a result of becoming a Singularity. She also says the matron died from draining all of her magical energy. In answer to Romani's question, Ishtar explains she and her vessel are essentially fused, with er being the majority. She continues that when a Divine Spirit and a human become a Pseudo-Servant, the Divine Spirit is the main personality since they possess more spiritrons. Suddenly the group are attacked by mountain spirits seeking vengeance on Ishtar.

After defeating the spirits, the group descend down the mountain by nightfall. They find an abandoned house, and while the others there Ritsuka takes first watch. Later, as it nears dawn, Ishtar talks with Ritsuka. While talking to them, she sneezes and her appearance changes to her own but with blonde hair. Unaware of the change, she asks Ritsuka for their opinion on the Alliance. She says it's impossible to negotiate with Gorgon, and she doesn't understand the southern goddess since they're from differing cultures. She continues that she won't forgive humans for overturning the rule of the gods. She believes living in the Age of the Gods is easier for humans as they can blame all their misfortunes on the gods. She then reveals she joined the Alliance to make a world for both gods and humans. After saying she is only an enemy of humanity's world, Ishtar goes to bed.

Returning to Uruk, Gilgamesh congratulates the group on their success. He tells them that 's axe, which they can use against Gorgon, is in Eridu. He asks Ishtar to tell him the identity of the southern goddess. She answers that the southern goddess is Quetzalcoatl. In answer to Romani's confusion about Quetzalcoatl not being male, she reveals the gods of Mesoamerica originated from an asteroid that collided with earth. The asteroid possessed a microscopic organism that changed the local animals into gods who built the Mesoamerican civilization. The gods of Mesoamerica also possess humans to serve as their vessels. Gilgamesh then orders Romani to gather information on Quetzalcoatl. Suddenly though, a soldier rushes in and reveals the south gate has been destroyed. Gilgamesh believes the attack is from Demonic Beasts, but the soldier reveals the attacker is Quetzcoatl whose heading straight for the ziggurat.

Outside at the southern market, soldiers try to fight Quetzcoatl, but she easily kills them. The group arrive just in time to see a soldier about to killed by her, but Ana saves him. Quetzcoatl then manipulates the wind to launch another soldier high into the air. Fortunately Ana uses her chain to save him before he falls to his death. After the soldier retreats, Quetzcoatl decides to fight the group, but their attacks are ineffective. She confirms she is part of the Alliance, and reveals she was summoned Mother to destroy humanity. But she refuses to use her Authority to destroy them instead opting to kill them one by one, with a limit of one hundred people a day. She then rides a pterosaur back to the jungle after warning she'll return tomorrow. The group then witness Jaguar Man stacking the dead soldiers onto a cargo slab. She sends a group of werejaguars to attack them before leaving.

After defeating the werejaguars, the group return to the ziggurat. Siduri states the soldiers and the craftsmen fleeing the southern market will hinder Gilgamesh's secret weapon project, but he stops her from saying more. As the group discuss how to fight Quetzcoatl, Romani surmises she is occupying the jungle covered Eridu. He assumes she built a temple dedicated to her there to increase her divinity in Sumer. Ana correctly surmises that the group will need to destroy the symbol of Quetzcoatl's power at the temple to lower her divinity. Gilgamesh then orders the group to go to Eridu to defeat Quetzcoatl and retrieve Marduk's axe. He says the trip will take a total of four days there and back. He continues they'll immediately begin preparations for the battle with Gorgon upon they're return.

Outside Uruk's south gate, Mash gives the gatekeeper the seal from Gilgamesh permitting the group's depature. The gatekeeper tells them that he was infected with the same infectious disease that has been infecting Uruk's populace for past few days. During Quetzcoatl's attack, she saw he was sick, and gave him a mango that cured his ailment once he ate it. After he pleads to the group to try talking to Quetzcoatl first, they depart for Ur.

Entering the jungle, the group discuss the possibility of negotiating with Quetzcoatl. Merlin and Ana assumes Quetzcoatl's Mother refers to Tiamat. He asks Ishtar if she and Quetzcoatl were ordered by Gorgon to eradicate humanity, but she deflects the question. Any further discussion is interrupted by the arrival of Jaguar Man who the group are forced to fight. Fortunately due to Ishtar's help, the group are able to defeat her. After being shot by Ishtar, Jaguar Man reveals herself to be a Rogue Servant. At Merlin's behest, Ritsuka easily convinces her to become an ally. She prepares to guide the group to Eridu, but werejaguars ambush them for her betrayal. Taking on a serious demeanor with modern clothing, she defeats her former minions.

Arriving at Ur, the group are shocked to see the Uruk soldiers Quetzcoatl had killed to be alive. Jaguar Man reveals Quetzcoatl revived the soldiers right after killing them. Merlin also reveals a report said outside the soldiers who were taken away, no other soldiers died in Quetzcoatl's attack. Ana correctly surmises the soldiers are forbidden from leaving Ur though. Jaguar Man says the soldiers, who are being restrained at Eridu, are to be part of Quetzcoatl's army. She also warns Ritsuka that the only way to convince Quetzcoatl would be to defeat her in a head-on battle of the soul. Later that night, Ishtar gives Ritsuka advice on how to fight Quetzcoatl.

The next day, the group guided to the jungle outside of Eridu, but Quetzcoatl has just returned from Uruk. Since her presence complicates things, Merlin asks Ritsuka if they should wait for her to go to Uruk, or wait for an opportunity to get into her temple. Ritsuka goes with the latter option, which the others agree with since there's no time to delay. Romani gives the group an overlay of Eridu, but he warns Quetzcoatl is currently at her temple. Jaguar Man says she, Mash, and Ishtar will hold her off while Ritsuka goes to destroys Piedra Del Sol at the temple's peak. She then gives them a spare of her weapon she made last night for this very purpose.

Going through the rest of the jungle, the group enter Eridu. As they gaze at the temple, waves of winged serpents attack them. They breakthrough them and reach the temple where they see Marduk's axe behind it. Quetzalcoatl greets the group, and speaks of how humans give her purpose despite the contradiction of her trying to destroy them. She explains she is helping humans adapt to their environment by helping some while killing others. It is for this purpose that she joined the Alliance. Correctly surmising the group's plan, she'll let Ritsuka to try to reach her stone while the others try to hold her off. She ask them if they feel the joy in the danger when Ritsuka realizes the joyous one Ziusudra spoke of refers to Quetzcoatl. After Ritsuka answers fighting means to give your all, Quetzcoatl fights the group. While the others hold off Quetzcoatl, Ritsuka reaches the temple's altar where Piedra Del Sol rest. Romani warns Quetzcoatl has defeated the others and is approaching the altar. He implores Ritsuka to destroy the stone, but they realize Quetzcoatl wants to see a display of human resolve. They decide to body slam her, so Ishtar takes them high into the air at Jaguar Man's suggestion. Quetzcoatl is caught off guard by Ritsuka throwing themselves from such a height, but she is able to save them at the last moment. Impressed by Ritsuka's resolve, she decides to join the group.

Due to the sheer size of Marduk's axe, Quetzcoatl proposes to tie a rope made of jungle vines to it, and have her winged serpents carry it to Uruk. She says the task will take three days, and her proposal is gladly accepted. Before she can get ready her winged serpents, the group defeat a group of spriggans guarding the axe. Afterwards, Quetzcoatl finishes the preparations to deliver the axe to Uruk. She then takes the group to see a cylinder seal in the center of Eridu before they need to return to Uruk. Merlin transcribes its inscription into the air to reveal the prophecy of Mesopotamia becoming a Singularity and Tiamat razing Uruk. The group realize Gilgamesh made preparations against the Demonic Beasts because he knew the prophecy on the seal. Thanks to his preparations and the resolve of Uruk's populace, Mesopotamia was able to stave off destruction for half a year before Chaldea arrived. Quetzcoatl then orders Jaguar Man to supervise the winged serpents carrying Marduk's axe.

Passing back through the jungle while slaying Demonic Beasts, the group reach Ur. Later that night, Ishtar tells Ritsuka that the law of the Alliance still bind her and Quetzcoatl despite their leaving. When she sees Ritsuka is unwell from fatigue, she take over their watch while listening to their stories about the Singularities. After hearing about the six main Singularities, Ishtar expresses her enjoyment about the unlimited potential of humans and adventure. Because of this she likes humans, and thus wants to protect them. She also wants to go on an adventure before she doesn't have the freedom to do so. Seeing dawn is nearing, she and Ritsuka try to get some sleep before the sun rises.

Returning to Uruk, the group learn that Gilgamesh has passed away, seemingly due to overexerting himself. However, Romani and Merlin disagree that he died in such a way. Merlin asks Siduri if anything strange happened in the city after the group left for Ur. Siduri answers there have been a number of deaths from weakness, which makes Quetzalcoatl realizes they were caused by one of the Alliance. She also reveals Ishtar isn't a member of the Alliance, and the third member is Ereshkigal. Realizing what Ziusudra's message to him meant, Merlin reveals Ereshkigal was summoned when Ishtar was summoned, and that it was Ereshkigal who killed the temple matron. He also says Ereshkigal is using Ishtar's body without her knowledge since she can't leave the underworld. Quetzalcoatl reveals Ereshkigal's gallû spirits are responsible for the deaths in Uruk, and assumes one took Gilgamesh's soul to Kur. Urged by Siduri and Merlin, the group head to Kur to rescue Gilgamesh.

At Kutha Ishtar says only she, Ritsuka, and Mash will enter Kur while Merlin and Quetzalcoatl stay behind. She explains gods have their powers nullified in Kur so they can't escape after they die. She then flies high in the air, and fires a giant hole in the ground leading into Kur. Ritsuka and Mash fall down into the underworld, followed by Ishtar entering.

Inside the underworld, Ishtar explains the narrow cages and the lights in them Mash sees are deceased human souls and soul cages. The soul cages prevents the soul from disappearing after the body dies, but they're tormented by the cold until Ereshkigal bores of them. Ishtar confirms Ereshkigal is responsible for the souls being forcibly taken from their bodies, noticing a greater number of soul cages than before. She wonders if Ereshkigal is trying to established a kingdom of the dead. She explains Ereshkigal is in her palace beyond the seven gates, trapped there as the gods had decreed. The trio then walk to the first gate, which Ishtar explains it will ask binary question that's fair and logical to test a soul's morality. There is no wrong answer, but they'll still have to complete a trial afterwards. However, the gate asks an illogical question with the answer being Ereshkigal or Ishtar. After Ritsuka gives their answer, the group are forced to fight some spirits. After defeating the spirits, the group pass through the first gate. However while Ritsuka and Mash pass through it safely, Ishtar is shocked and shrunken a little. Ereshkigal explains to her that she'll become smaller with every gate she passes through, losing 1/7 of her divinity at a time. She also tells Ritsuka that she'll accept them and Mash as visitors to Kur if they pass her trials. At the third gate, it becomes apparent that choosing an answer favoring Ereshkigal makes the following combat trial easier while choosing an answer favoring Ishtar makes it harder. The group then find Gilgamesh who explains he hid from the gallû spirits so they couldn't capture him. Since he's dead though, he cannot leave the underworld, so the group still need to defeat Ereshkigal before he can return to Uruk. After they pass through the third gate, he reveals that before Chaldea's arrival he discovered Enkidu's remains missing from their grave. This makes the others realize that Kingu's body is actually Enkidu's. After passing through the remain gates, Ishtar has shrunken to palm size. Nonetheless the group enter Ereshkigal's palace to confront her.

Inside her palace, Ereshkigal appears before the group, and changes the atmosphere to the equivalent of a mountain top. Because of that Romani implores Ritsuka to defeat her before they die from the frigid conditions. Ereshkigal then sheds her guise as a gallû spirit to reveal her true form. She believes Ritsuka should be surprised she looks similar to Ishtar, but they reveal they've already to see her true form. They also reveal to her she showed her true form when she sneezed while speaking to them as Ishtar every night. Overcoming her utter embarrassment, Ereshkigal announces she'll conquer Uruk and seize its Grail before Gorgon destroys the city. Thus, the remaining humans on the surface will become her property in the underworld. Gilgamesh asks Ereshkigal why she abandoned her duty and joined the Alliance, preparing to execute her depending on her answer. She answers she still obliges to her role of managing all humans souls within the underworld. As the group stand her in her way of her plans, she decides to kill them all. Before that though, she asks Ritsuka if she should be punish her for upholding her duty all this time alone. Ritsuka is uninterested though as they understand Ereshkigal is only fulfilling her role. After Gilgamesh explains Ritsuka is telling her work is praiseworthy, Ereshkigal fights the group in her gallû spirit form. After Ereshkigal is defeated, Ishtar is returned to normal size, and Gilgamesh is unbound from the underworld. Ereshkigal prepares herself to be execute, seeing it only just to do so as she was persuaded by Solomon to conquer Uruk. She explains she wanted to gather all of the human souls into the underworld so she may rule over humanity. She believes her wish for domination over humans is a greater evil than Gorgon's wish to destroy them, but Ritsuka calls her a liar. After declaring she hates the living, Ereshkigal is seemingly cut in half by Ziusudra. Ziusudra explains though that he didn't kill her, rather he served her bond with the alliance. Gilgamesh demands to who he is, to which Ziusudra answers he has come from the abyss to set events in motion. He then asks Ereshkigal why she wanted to create a kingdom of the dead, understanding she wanted to dominate humanity out of love from them. When she claims to love only the dead, he and Ritsuka call her liar as they know she loves all humans. Ziusudra then explains Ereshkigal joined the alliance in order to protect as many souls as she could in the underworld. As she begins to lament over she has done, Gilgamesh tells her that bodies whose souls were taken are still stored away, so the souls only to be released from the cages to revive their bodies. He also tell her that the damage she caused to Sumer is negligible compared to Gorgon to her surprise. Ereshkigal says she will not attack Uruk, and while she won't contract with Ritsuka, she'll still help them to repay their kindness. After she returns to her duties, the group return to Uruk.

The group return to Uruk where Ana welcomes back outside the gate. After she leave to help some bulls, the group head to the ziggurat to see Gilgamesh. He immediately begins the strategy meeting for Gorgon upon them entering. Siduri details that Gorgon's forces consists of roughly 100,000 Demonic Beasts gathered in the Cedar Forest currently. Since the beasts outnumber the remaining forces at the Northern Wall by ten times, she fears the Northern Wall won't last half a day if it's invaded, even shorten if Gorgon herself appears. Gilgamesh orders the group to go to Gorgon's base, the Blood Fort, while the forces at the Northern Wall hold off her forces for half a day. The Blood Fort is located in the underground lake deep within the Cedar Forest. Mash states Gorgon will lose much of her Authority once the Blood Fort is destroyed. Ishtar questions how they can destroy it, as the entrance is protected by a Bounded Field. Gilgamesh states Marduk's Axe, which was delivered in the morning by Jaguar Man, will be used to destroy the Blood Fort. Quetzalcoatl questions if her winged serpents can carry the axe from the Northern Wall, where it was relocated to, to the Cedar Forest in half a day. Gilgamesh suggest she throw it instead, which she confirms she can do. However she explains she still bound to the Alliance's rule to not attack each other, and any who break that rule are completely annihilated. Merlin devises a plan where he and Ritsuka will sneak into the Cedar Forest and head to the Blood Fort. Once they're close enough, he'll signal Quetzalcoatl who'll throw the axe to him. In case her aim is off, Merlin wraps a bit of red cloth from his staff around the axe to ensure it reaches him, as the cloth and his staff are one and the same. Gilgamesh states the operation will begin at dawn tomorrow, and the Northern Wall will distract the Demonic Beast while Ritsuka's party sneaks through the Cedar Forest to the Blood Fort's entrance.

Travelling via a carriage summoned by Merlin, the group reach the Northern Wall four hours before daybreak. While the others are resting, Ritsuka talks with Ana on the wall. There she reveals her dislike of humans stems mostly from their habit of condemning the old and ordinary as evil and useless. As an explain of that, she tells Ritsuka about a blind old lady living disheveled house protecting flowers that she helped as a job. Yet despite her blindness and loneliness, she looked happy, and treated Ana with kindness. Ritsuka gives her a floral headpiece the old lady made for her, but she rejects it believing she doesn't have the right to have it. She then leaves saying that she now fights for Uruk's people not just herself. Later, Merlin appears and confirms at Ritsuka's behest that he was the one who sent Bedivere to the Holy Land to correct the Lion King Artoria's mistake. He goes on to explain that due to his half-incubus lineage, he was able obtain a sense of purpose unlike pure incubi. He became a sage because he learned people would accept him if he was one. Despite studying humans and their emotions, he still couldn't understand them nor can he fully experience their emotions. Yet despite saying that, he states human history is the one thing that brings him happiness.

The next day, Merlin tells the group that the soldiers will battle the Demonic Beasts an hour after they leave. Once they get confirmation the battle has begun, they'll head through Babylon to the Cedar Forest, and from there head to the Blood Fort. Quetzalcoatl and Jaguar Man will stay behind to help defend the Northern Wall. The group head towards the ruins of the Babylon where they slaw a pack of Demonic Beasts. As its been a hour after they left, Merlin asks Romani about the current situation at the Northern Wall. He answers the first wave of Demonic Beasts have passed through the Nippur, and will engage against the soldiers in five minutes. He continues the Demonic Beasts are being led by Kingu. Meanwhile back at the wall, the battle against the Demonic Beasts has already begun. Seeing Quetzalcoatl keeping Kingu at bay, the group head towards the Cedar Forest.

Traveling through the Cedar Forest, the group eventually find the Blood Fort. Merlin sends up a massive flare to signal Quetzalcoatl who throws Marduk's Axe to destroy the temple's entrance. Inside the temple, the group find its walls be lined with cocoons containing humans being turned into Demonic Beasts. Romani warns them Kingu is heading their way, and urges them to defeat Gorgon before they arrive. Lead by Ana, the group eventually confront Gorgon in the deepest part of the Blood Fort. Mash asks Gorgon what she want revenge on, but she answers she merely wants to destroy humanity for hating her. After Ritsuka and Mash reject her reasoning, Ishtar calls her a fake who became Tiamat through the Grail's power. She further mocks Gorgon saying the real Tiamat would never use the target of her revenge to get her revenge. Ana agrees with her, and calls Gorgon a monster who lost sight of herself. Seeing Ana suddenly sends Gorgon into a panic as she pleads for someone to kill Ana. Ritsuka deduces Ana's true identity is Medusa, who decides to slay her monstrous self. Merlin tells her action will release the Divinity she held back all this time, which she is fine with. With the other's help, she fights Gorgon while using her Mystic Eyes to offset Gorgon's own. With her defeat, the room begins to collapse yet Gorgon is still immortal and her wounds are already healed. She states she is hearing the voice of a sobbing Mother for whom she's taking revenge for. Ana then slays her with Harpe, with both seemingly dying in the process. Ritsuka lays the floral headpiece meant for her to serve as a grave marker. Romani however states he is getting a reading on the Grail, which Gorgon should've had. Merlin ays she used the Grail to regain her former Divinity yet she possess it herself. As he deduces where the Grail is, Kingu arrives to find Gorgon had already dead. Before fighting the group, they reveals the Demonic Beasts will all die as they only lived because of Gorgon's power. After the fight, Romani reports an number of spatial rifts are suddenly occurring all over Mesopotamia. Merlin is suddenly injured as he realizes what is happening, to which Kingu reveals he trapped Tiamat in a dream to postpone her reveal. They further reveal that she created them and gave them the Grail while asleep with the task of awakening. Merlin realizes Gorgon had gained Potnia Theron by synchronizing with Tiamat, and with her death Tiamat will awaken. As a result of her awakening, Tiamat found Merlin in her dreams and severely wounded him. Seeing the Alliance is no longer necessary, Kingu announces the return of Tiamat. Meanwhile outside at the Persian Gulf, the sea is covered by black mud, and a growing horde of millions of strange creatures also appear. After Kingu leaves, Merlin urges the others to return to Uruk to tell Gilgamesh that one of the Beasts has awoken before disappearing.

Outside the Blood Fort, Romani warns the group of a massive amount of lifeforms are emerging from the Persian Gulf, and they're spreading across all of Mesopotamia at an incredible rate. When Ishtar asks him how long it'll for them to reach Uruk, da Vinci intervenes saying she is taking charge while Romani concentrates on analyzing the lifeforms. She answers Ishtar that around 20,000 of of the lifeforms are heading for Uruk, with an ETA of under three hours. She continues that Eridu has already been attacked, and Ur has an about hour before its attacked. Ishtar goes at supersonic speeds to Uruk ahead of Ritsuka and Mash. Da Vinci orders them to go to the Northern Wall, as it's currently the safest place with it being the furthest from the Persian Gulf. Ritsuka wonders what happened to Merlin, to which Romani answers Merlin's true body was killed when Tiamat woke up, and that the Merlin that interacted with them was apparition.

Ritsuka and Mash travel to Babylon where they encounter Quetzalcoatl. Mash tells her that Merlin is gone, Ana died killing Gorgon, and Ishtar has gone ahead to Uruk. Quetzalcoatl tells the pair that the remaining Demonic Beasts have fled into the forest. She reveals Marduk's Axe lost its Divinity when the Blood Fort was destroyed, and she also lost nearly half of her Divinity. Mounting onto her Quetzalcoatlus, the group fly towards Uruk. Meanwhile in Ur, Benkei defends its citizens from the strange creatures. However he's taken by surprise by the appearance of a familiar person, and he's seemingly killed by them and the creatures.

The group arrive over Uruk to see it burning while Ishtar struggles against the strange creatures. She pleads the others to land and intercept the creatures, and to secure a path to the ziggurat so the citizens can take sanctuary there. Meanwhile on the ground, the strange creatures are slaughtering the civilians and soldiers whose weapons are worthless against them. The group land just in time for Mash to defend a soldier, then they fight the creatures. However they're soon overwhelmed by the sheer strength of merely one creature, which worse by the fact that they're multiplying. Surprisingly the creatures leave, so the group go to the ziggurat with Ishtar. Inside the ziggurat, Gilgamesh orders the surviving citizens to be moved beyond the Northern Wall, and to use Nippur as a temporarily refugee base. Ritsuka tells him of Merlin's warning that Solomon had summoned one of the Evils of Humanity. Gilgamesh reveals the Evils of Humanity are seven entities that destroy humanity, and becoming stronger the more humanity develops. He says though they're not evils that destroy humanity rather they're evils that humanity destroys. He continues they are the original basis for Heroic Spirits, and they're born from humanity's bestial nature, thus their class is Beast. He reveals Tiamat is one of the Beasts, and she has yet to be fully awakened. Quetzalcoatl guesses Tiamat is inside the blackened sea at the Persian Gulf, and that it's the source of the strange creatures. At Gilgamesh's behest, Romani reveals the creatures are made from the Mud of Gods, and compares them to mass produced Enkidus. He names them Laḫmu after Tiamat's first child whose name meant mud; Ishtar is surprised he knew their identity. Gilgamesh reveals the Laḫmu are not just slaughtering the people of Mesopotamia, but also kidnapping them. He continues that reports state the kidnapped were taken to Eridu, and the Laḫmu have made it and Ur their nest. He orders the group to ignore Eridu and go to the blackened sea. He reminds Ritsuka that the Foundation of Humaity will collapse completely if Uruk falls, thus Humanity along with Chaldea will be incinerated. When Ritsuka asks where Siduri is, Gilgamesh reveals she was taken by Laḫmu, and changes his order for the group to Eridu.

Meanwhile at Eridu, Kingu asks Solomon why Tiamat has yet to emerge, to which he reveals she is currently sealed. He also reveals they're responsible for restoring Gorgon's Divinity, and they formed the Alliance. While he does commend their efforts, Solomon orders Kingu to break Tiamat's seal so she can destroy Uruk, thus destroying humanity. He then leaves after asking Kingu if Tiamat really wants to create a new humanity like they believe. Kingu wonders why Tiamat created the Laḫmu after observing them torture another human to death, though they ignored it. They try to hear Tiamat's voice by closing their eyes, but they're unable to since the sea was blackened. They then leave to break Tiamat's seal, wondering who has the power to seal her.

Outside Uruk, the group watch as the survivors evacuate to the Northern Wall, and the soldiers still defend the city. Later, they arrive at Ur to find everyone to have been killed their homes. The group ponder why the Laḫmu kill humans without reason when a group of Laḫmu arrive. After fighting the Laḫmu, they head to Eridu where they find the kidnapped victims gathered in the plaza. A single Laḫmu appears before them, but it doesn't try to fight them. Deciding to ignore the strange Laḫmu, the group go to the plaza. There they witness the Laḫmu forces humans to kill each other, though none are spared even if they follow instructions. After some of the Laḫmu are defeated, the surviving humans try to run to the jungle but some are killed by the Laḫmu. Kingu suddenly attacks and asks them why they're gathering old humans. The group take this as their chance to lead the survivors to safety. Kingu criticizes the Laḫmu for killing without purpose, as they reason humans aren't even a threat. They wonder if Tiamat made mistake in creating the Laḫmu, calling them defects lower than Gorgon's Demonic Beasts. They order the Laḫmu to fall back, still believing themselves to be one of Tiamat's children like the Laḫmu. Mash however reveals to Kingu that they're not Tiamat's child, and their body is actually Enkidu's body. She believes they're a synthenic Demonic Beast created from Enkidu's corpse for the purpose of awakening Tiamat. Kingu declares themselves to be still Tiamat's child even if they weren't born from her. The Laḫmu then reveal that Tiamat to learn as the new humans from the old humans. However all they learned from humans was how to kill for the pure enjoyment of it. A Laḫmu then rips the Grail from Kingu's body, which makes Romani realize Gorgon retrieve its power through Kingu. The group try to take the Grail from the Laḫmu that seized it Kingu. However it's defended by the other Laḫmu, as it swallows the Grail and grows a pair of wings. The group fight it to prevent from flying to Tiamat to fully awaken her. Meanwhile in the jungle, Kingu tries to fight the Laḫmu chasing them, but their attacks are rendered useless without the Grail. Back in the plaze, the winged Laḫmu, Bel Laḫmu, flies away, so Ishtar tries to give chase when the other Laḫmu weigh her down. The others mount Quetzalcoatlus and chase after Bel Laḫmu in her stead. Before leaving though, Quetzalcoatl orders Jaguar Man to evacuate and protect the humans.

The group chase Bel Laḫmu to the center of the Persian Gulf where Tiamat is located. Romani warns if the Laḫmu drops the Grail there, then its magical energy will awaken Tiamat. Quetzalcoatlus eventually catches up to Bel Laḫmu and rams it. It crashes onto the shore, so Romani orders the group to go finish it off and take the Grail. Meanwhile back in the jungle, Kingu is still being chased by the Laḫmu. They eventually found, but as they resign themselves to death, they're saved by the strange Laḫmu. Addressing them as Enkidu, It tells Kingu to run and find happiness, and thanks them for being Gilgamesh's friend. After it dies, Kingu is tormented again by Enkidu's memories.

At the Persian Gulf, the group are knocked out of the sky by Ushiwakamaru, whose been corrupted into one of Tiamat's Children. They kill her and try to chase after Bel Laḫmu, but multiple Ushiwakamaru appear. Romani realizes Ushiwakamaru can multiple like the Laḫmu, and reveals she can't be destroyed as her Spirit Origin is mixed with the blackened sea. Ushiwakamaru boasts only the light bands have the power to destroy the blackened sea, to which Quetzalcoatl claims she has a Noble Phantasm capable of just that. While the group were fighting Ushiwakamaru though, Bel Laḫmu had delivered the Grail to Tiamat. After Ushiwakamaru reveals herself to be essentially undead, a large number of Laḫmu emerge from the sea. After Ushiwakamaru converts into mud and sinks into the sea, Mash opts for the group to go protect Uruk, but Ritsuka says they need to go to the observatory.

Inside the observatory, the group are contacted by Gilgamesh who reveals he created a communication system based on Chaldea's own when he went to the observatory with Ritsuka and Mash. Jaguar Man tells them that the Laḫmu attacked Uruk again, but the city was protected thanks to Gilgamesh's Dingr. Gilgamesh warns though that neither the solders nor his magical energy will last much longer. Ritsuka reports Tiamat now has the Grail, and Quetzalcoatl reveals Tiamat used it to control Enkidu's corpse. Gilgamesh then reveals the blackened sea is Tiamat's Authority, which converts any who touch it into her children. Ishtar then arrives and reveals Tiamat's Authority includes self-modification, multiplication, bio-fusion, and the most powerful one, Amino Geas, or cell compulsion. She then tells the group that she evacuated Eridu's remaining population to the basement of the ziggurat. Gilgamesh reveals the sea level started to rise when Tiamat retrieved the Grail, and warns the sea will overflow onto the land in three hours. He further warns the blackened sea will convert the remaining people of Mesopotamia into Tiamat's monstrous children, which will collapse the Foundation of Humanity. Romani then tells the group that the way to stop the blackened sea is to defeat Tiamat herself.

Returning to the Persian Gulf, the group slay a number of Laḫmu and Demonic Beasts emerging from the sea, as they head towards Tiamat. Eventually they encounter Tiamat, who Ishtar reveals was exiled to the World of the Void after she was deemed unnecessary when the environment settled and life was established. Seeing her limbs are still bound, the group go to kill Tiamat before she unleashes a blast equal to a hydrogen bomb towards Uruk. They defeat her, but Mash believes she was letting the group attack her. However, Tiamat's true body emerges from sea, sending a wave of the blacked sea that swallows the observatory. Understanding she impossible to even injure, Romani orders the group to immediately return to Uruk. Tiamat begins to move towards Uruk, sending another wave towards Uruk. Meanwhile, a soldier reports to Gilgamesh that the wave already destroyed Girsu City, and is now flowing towards Umma and Uruk. Gilgamesh orders the Fangs of Napishtim to be deployed, which manages to divert the wave. The soldier warns the Fangs were severely damaged in the process, so Gilgamesh orders them to repaired.

The group return to Uruk's ziggurat where they learn that there are only 500 humans left in Sumer. Gilgamesh says the first dynasty of Uruk has fallen as a result, but he believes civilzation will continue as long as Sumerian culture survives. He then explains the Laḫmu are split into two groups: one turn into spheres at sunset and another flies to protect Tiamat's surroundings. He reads Romani's analysis report on Tiamat, but is disappointed it doesn't note any weakness. Jaguar Man tells him that Tiamat will reach the coast in half a day at her current speed, guessing it'll a take a day to reach Uruk. When Ritsuka asks why she's targeting Uruk, Quetzalcoatl answers it's because the city and Gilgamesh are symbols of Sumerian civilization, thus she wants to destroy it. Romani theorizes Tiamat is invincible due to the fact she cannot die as long as life exists on land. Gilgamesh impressed by Ritsuka having the same train of thought as him, calls Ereshkigal with the Mirror of Kur she lent him. Gilgamesh asks her to send Tiamat to the underworld where she'll be considered the last living being, thus negating her invulnerability. He orders Ereshkigal to open the gate of the underworld across Uruk and bind Tiamat in the underworld. She tells him would originally take her ten years to complete such a task, but says it'll now take three days after revealing she plotted something in Uruk beforehand. Quetzalcoatl notes however the time issue of Tiamat's arrival and Ereshkigal completing her task. Gilgamesh and the others says Ishtar can use Gugalanna to hold Tiamat back. But to everyone's dismay, she reveals she lost Gugalanna who she was looking for Babylon when she first met Ritsuka and Mash. as punishment for her incompetence, Gilgamesh forces her to stand in a corner holding a clay tablet that reads: "Worst Goddess". Realizing they now have no way to combat Tiamat, everyone takes a break.

Later that evening at the embassy, Ritsuka asks Quetzalcoatl if she knew about Tiamat. She answers she knew about Tiamat and Gorgon synchronizing with her consciousness, which deluded her into believing she was Tiamat's second coming. She couldn't tell either Ritsuka or Gorgon the truth despite wanting to be friend. But she was able to tell Ritsuka some of the truth by showing them the prophecy inscribed in the cylinder seal at Eridu. When asked why she didn't tell the truth, Quetzalcoatl answers she wanted humanity to truly hate Gorgon, so they could fight her with all they have instead of pitying her as a fake Tiamat. Ritsuka asks her why she joined the Alliance, and she begins to answers she wanted to kill humans. Jaguar Man interrupts her to reveals she joined to stop the other goddesses by trying to get the Grail of Uruk first.

Later at night, Ritsuka and Mash meet with Gilgamesh at the ziggurat while he goes over his plan. He reveals he told the people of Uruk that the city would be destroyed in six months ago as he foresaw when Solomon sent his Grail into the era, and pulled Tiamat from the World of the Void. He continues Tiamat would have still appeared even if Uruk defeated the Alliance, which he hoped would destroy itself. He commends Ritsuka for fighting the Alliance for the sake of the Uruk's people, which resulted in 500 sumerians surviving when they were fated to die. He then reveals, unlike Ritsuka and Mash what were told, that everything that occurred in a Singularity won't be reversed when the Incineration of Humanity is stopped. He explains even if a Singularity where someone is killed disappears, that person would still be dead in the proper history with only their method of death being different. As such the fall of the first dynasty will still fall even if the Singularity, with only the explanation of how it fell changing. Nonetheless Gilgamesh tells Ritsuka and Mash that their actions still had meaning, and says only those who come after will know the result of their actions. Afterwards on Celestial Hill, while the others are resting, Gilgamesh meets with Kingu, who driven there by Enkidu's memories. He then gives them the Grail of Uruk to serve as their new heart, and tells them that they're worthy of his friendship as he sees them as Enkidu's successor. He then leaves, telling them to do what truly want to.

The next day, the group look over a diagram of Tiamat's true form that Romani made collaborating with Uruk's priests. Gilgamesh tells them of the reports from the surviving academic facilities that theorize Tiamat's legs are too thin to support her giant, and that she can only on water. Believing the theory to be true, he orders the destroy the black mud, Chaos Tide. A soldier arrives to report that Tiamat is continuing her advance and she'll arrive at Uruk in eight hours. Gilgamesh decides they need to destroy her legs, and prepares to order his soldiers into battle when Quetzalcoatl interrupts him. She says she can use Piedra del Sol to destroy the Chaos Tide in Tiamat's perimeter once she comes ashore. Since her Noble Phantasm uses a lot of stamina though, she needs to be close enough to Tiamat, and continuously supplied with magical energy while she deploys it. Agreeing with the plan despite its dangerous, Gilgamesh orders the soldiers to stay on the city walls, and orders the group to enact Quetzalcoatl's plan.

After listening to Gilgamesh's speech while outside Uruk, the group go to the Persian Gulf. Upon arriving there, they fight the Laḫmu while advancing towards Tiamat, but there are too many for them to handle. The Laḫmu's attention is diverted when survivors of Girsu attack them, so Quetzalcoatl order Jaguar Man to protect them. Eventually the group catch up to Tiamat when Ushiwakamaru appears to kill them. However due to her connection to the Chaos Tide, the group are unable to truly kill Ushiwakamaru. When asked why she wants to kill humans, she answers humans selfishly take advantage of and dishonor those who performed selfless deeds. After saying starting over is the only way left for the world, more copies of her appear. But, as her copies prepare to kill the group, Benkei arrives and grabs her. Ushiwakamaru's copies impale both of them, but Benkei still lives and sacrificially uses The Pilgrimage of the Five Hundred Arhat to disconnect her from the Chaos Tide and destroy her. With Ushiwakamaru now gone, Quetzalcoatl unleashes Piedra Del Sol and incinerates the Chaos Tide in Tiamat's perimeter. However, when it reemerges from Tiamat, she prepares to deploy her Noble Phantasm while the Bel Laḫmu attack her. She stops though when she see Tiamat using her horns to fly. Despite her various wounds, she still uses Xiuhcoatl on Tiamat, but her attempt fails and she falls into the blackened sea. Tiamat then discharges more of the Chaos Tide, unleashing more Laḫmu along with it. The group slay the Laḫmu, but Romani warns the Chaos Tide has destroyed the Fangs and is now flowing towards Uruk. Tiamat tries to fly towards Uruk when several large black snakes appear to drag her down. The Laḫmu try to remove the snakes when Gorgon arrives and kills them. She tells the group to retreat back to Uruk while she stays and destroys Tiamat's wings. Mash offers to help, but Gorgon points out how they can fight the Laḫmu, lost Quetzalcoatl, and Ritsuka's emerging necrosis from being drained of their magical energy. Ritsuka decides to heed her despite them and Mash knowing Gorgon is Ana. After the group retreat, Gorgon uses Pandemonium Cetus to destroy one of Tiamat's right horn at the cost of her own life. Yet despite losing one horn, Tiamat is still flying towards Uruk. The group rush towards Uruk before another wave of the Chaos Tide swallow them.

The group arrive back at Uruk only to discover of they, Gilgamesh, and eight soldiers fighting the Laḫmu are the only ones left alive in the city. Breaking through the Laḫmu and Demonic Beasts, the group meet Gilgamesh on Celestial Hill. From there they see that the Chaos Tide has already flowed into the city. When Tiamat arrives, Gilgamesh orders Ishtar to fly above the clouds directly under the sun and await his instructions. He then fires all of the Dingir, which were created by him, infused with his magical energy, and controlled by him, at Tiamat. He takes a shot to heart however when he protected Ritsuka from Tiamat's blast meant for him. Yet despite his mortal wound, he still fires the Dingr. Romani urges Ritsuka and Mash to escape into the ziggurat, as he warns Tiamat will arrive there in three minutes, and the emergence of 8000 Laḫmu. The Lahmu clump together into a mass equaling Gugalanna's hoof to destroy the ziggurat's roof, knocking Ritsuka and Mash out cold. Ishtar prepares to fight the Laḫmu there when Kingu arrives and kill 2000 of them. Declaring themselves to be the only member of the new humanity, they decide to heed Gilamgesh's words, and uses Enuma Elish to bind Tiamat. She soon breaks the chains, thus killing Kingu, and continues to advance to Ziggurat. Ereshkigal contacts Gilgamesh to report the completion of task, so he orders Ishtar to create a massive hole in Uruk down into the underworld. As she prepares to do so, he tells Ritsuka that his death is necessary part of the proper course of history. Tiamat then arrives at the ziggurat when Ishtar's Noble Phantasm impacts it and creates a hole into the underworld, killing Gilgamesh and sending Ritsuka and Mash fall down.

As Ritsuka and Mash falls down into the underwrold, Ereshkigal grants the pair to float in the underworld. They land and see that Tiamat and Uruk have both fallen into the underworld thanks to Ishtar destroying the city's foundations. Ereshkigal with the gallû spirits then attack together to finish Tiamat off, but it's rendered ineffective as the Chaos Tide begins to corrupt the underworld. Tiamat then transforms into her true form as Beast II, and births more Laḫmu that spread throughout the underworld. Jaguar Man then arrives to help the group, and reveals the Chaos Tide will cover the world in less than a day if Tiamat returns to the surfrace. Romani confirms the Chaos Tide has covered most of the underworld, and implores the group to destroy it there before it reach the surface. Fortunately, Tiamat's paradoxical restoration is still ineffective in the underworld, as both the Chaos Tide and the Laḫmu are part of her. Flowers summonsed by Merlin then appear on the Chaos Tide to stop it and drain Tiamat's Authority from it. Merlin reveals he took advantage of the Earth's blank state from the Incineration of Humanity to temporarily physically escape Avalon and return to Uruk. Tiamat then grows wings on her back, and prepares to fly back to the surface. However, Ziusudra arrives and reveals himself to be King Hassan, the Grand Assassin, and severs Tiamat's wings while simultaneously forcing the concept of death onto her. Recognizing her own mortality, Tiamat unleashes more Laḫmu to protect her while she tries to escape to the surface. Ritsuka, Mash, and Merlin then, with Ereshkigal's blessing, fly up towards Tiamat's head where her spiritual core is located. The group breakthrough a number of Bel Laḫmu, but they prove too strong and numerous to handle. Aided by Hassan, the group breakthrough the Bel Laḫmu and reach Tiamat's head. They try to kill Tiamat before she reaches the surface, but she is astoundingly durable. She then takes out Merlin, thus removes his negation of her Authority from the Chaos Tide. Gilgamesh, as an Archer class Servant, then appears to help the group fight Tiamat. After she is defeated, Tiamat detaches from the wall she scaling, and falls down to the bottom of the underworld. Romani warns the group to escape back to the surface, as Tiamat begins to explode.

As their battle was in the air, Ritsuka and Mash to escape back to the surface before Tiamat exploded. Mash finds she had the Grail in her hands when she arrived back in Uruk. Merlin reveals he was the one who retrieved it when it spilled out of Tiamat's throat. Quetzalcoatal then appears and puts him in a joint lock, as Jaguar Man reveals she saved her. As the Singularity has been resolved, the Servants begin to disappear, along with Gilgamesh. He also reveals he summoned his Archer self to help fight Tiamat earlier. He gives Ritsuka and Mash the Grail of Uruk, passing it off as gift of wheat ale. After he disappears, the pair begin to be forcibly rayshifted back to Chaldea. Before he returns to his tower, Merlin tells Ritsuka he helped them because he was very interested in their struggle to restore humanity. He continues only he will remember everything that happened in the Singularity. He also reveals he and Hassan were able to manifest in the Singularity due to the appearance of a Beast. After he leaves, Ritsuka and Mash return to Chaldea.

Salomon: The Grand Time Temple
Salomon: The Grand Time Temple (冠位時間神殿) was the Final Singularity (終局特異点) of the Human Order Incineration Incident, occurring in A.D. 2016.

Setting
The Singularity occurred in the year 2016 within Ars Paulina. During his reign and lifetime, Solomon created seventy-two familiar called Demon Gods, which are collectively known as Goetia. Goetia was created as both the foundation for human magecraft, and a ritual to watch over humanity. He ruled alongside Solomon, but despite seeing and experiences the things, they both reached different conclusions about humanity. He came to hate both humans and Solomon; humans for the atrocities they committed; Solomon for ignoring the suffering and cruelty of humans, and wishing to not correct them despite his God given powers. When Solomon died, Goetia continued to exist as a primordial curse. He proceed to incarnate himself through a summoning spell, and took control of Solomon's corpse. Believing the fear of death is why human life is meaningless, he sought to recreate the planet so death doesn't exist. He conceived a plan to destroy humanity so he could gather and use 3000 years worth of magical energy travel back to the planet's genesis. There he will absorb the energy into himself, and recreate the planet as per his vision. As the first part of his plan, Goetia implanted Demon Gods as a curse into distinct mage lineages where they'll be passed down until they're awakened at their appointed era. Afterwards, he went to Ars Paulina, a reality marble and workshop existing outside space and time, to await the Demon Gods's awakening. Once they were all awoken, he proceeded to activate the Singularities to fracture human history, thus initiating the Incineration of Humanity. With humanity incinerated, Goetia gathered the magical energy into Ars Almadel Salomonis, creating the band of light seen throughout the Singularities.

History
As Ritsuka and Mash rayshift to the Singularity, they both see a vision of someone speaking how it can't bear the endless suffering. Their clairvoyance reveals all the horrible truths of past and future, thus as king, they cannot ignore it. They're forced to witness all the horrors of the worlds, which are burned into their memory. They decide all way to rectify the repulsive state of the world is to destroy humanity. However, as long as humans continue to reproduce, the world cannot be fixed. Thus they decide everything must be redone, and perfected right from the beginning, from true nothingness. Their plan is to recreate the planet from its beginning, which requires the massive amount energy generated by incinerating all life on the planet across 3000 years.

Waking up from the vision, Ritsuka and Mash find they've arrived at Time Temple. Leonardo da Vinci tells them that she is getting a reading of a Beast throughout the entire space. Lev Lainur Flauros confirms this, and commends Chaldea for getting past the Seventh Singularity. He expresses his surprise that Ritsuka made it this far despite their inexperience, having knowledge of their previous battles with the other Demon God Pillars went. He tells Ritsuka to die, disgusted by their persistent survival. Mash asks him if he intended to destroy Chaldea and humanity from the very beginning, a question Romani Archaman and Da Vinci both want answered. Lev answers he has been serving Solomon for 3000 years, and reveals Demon Gods were implanted in mage lineages until they're awakened at their appointed era. He was the one designated for 2016 A.D., and when he awoke as the last Demon God, humanity was incinerated. He is curious why Chaldea continued to survive, and ponders if he underestimated Romani's true nature. Da Vinci reveals Romani had spent a decade preparing for the Incineration of Humaity that he envisioned in a dream without letting his enemies or his allies know. Lev states he found Romani's behavior suspicious, thus he tried to kill him in the Control Room explosion. That plan was thwarted however thanks to Ritsuka's intervention, but Lev decides to ignore it now. Stating Solomon's final calcuations will be complete in a few hours, he transforms into the Flauros to stop Ritsuka and Mash from reaching the Throne. The pair kill him, but he is immediately reborn, calling everything they do pointless. Ritsuka realizes what the ground actually is when Chaldea is attacked by eight Demon Gods. Flauros reveals the entire space is Demon Gods, and calls upon for more Demon Gods to unveil themselves. He reveals that as long as the Throne exists, they will always be seventy-two Demon Gods. He then mocks Ritsuka's efforts through the Singularities, and goes to kill Ritsuka. However he is thwarted by Jeanne d'Arc, as he and the eight Demon Gods are eliminated by her and other Heroic Spirits summoned autonomously through their connection with Ritsuka. The Demon Gods report that the Servants are overpowering them, confused as to how humans can work together. Jeanne answers she and the Heroic Spirits answered Ritsuka's call to save humanity because they believed in them. She then rallies the other Heroic Spirits to clear a path for Ritsuka. As Mash watches more Servants being summoned, Romani reports all the Demon Gods are currently being engaged by the Servants. Believing they now have a chance, he implore Ritsuka to open a path to the Throne before it's too late.

With the help of the Orleans Singularity Servants, Ritsuka and Mash are able to defeat Naberius and the Demon Gods administrating the Melting Furnace. Together with the Septem Singularity Servants, they defeat Flauros and the Demon Gods administrating the Information Center. . With the Okeanos Singularity Servants, the pair defeat Forneus and the Demon Gods administrating the Observatory. . The Servants of the London Singularity help the pair defeat Barbatos and the Demon Gods administrating the Control Tower. . Ritsuka and Mash are aided by the America Singularity Servants in defeating Halphas and the Demon Gods administrating the Armory. The Camelot Singularity Servants help defeat Aamon and the Demon Gods administrating the Gazing Star. . The Servants of the Babylonia Singularity help Ritsuka and Mash defeat Sabnock and the Demon Gods administrating the Chamber of Life.

As the Servants aiding Chaldea continue defeating the Demon Gods, Baal asks Solomon to activate Ars Almadel Salomonis to incinerate the Heroic Spirits. Solomon tells him the Heroic Spirits will keep returning no matter how times they're destroy, as long as Ritsuka exists. Thus, the Demon Gods need only to kill Ritsuka while continuing to fight the Heroic Spirits. Solomon orders Baal to keep fighting the Heroic Spirits, believing the Demon Gods are immortality as long as he exists.

After conquering seven terminals protecting to Solomon's Throne, Romani is shocked to see an eighth terminal. He explains the Heroic Spirits who aided Ritsuka and Mash with the previous terminals were connected to the Seven Singularities. But there is no such connection with this terminal, so Ritsuka and Mash prepare to conquer alone. However, a number of Servants from the minor Singularities and Singularity candidates arrive to help the pair defeat Andromalius and the Demon Gods administrating the Trash Heap.

With Demon Gods' activity diminished by their constant fighting with the Heroic Spirits, a path is now open to the Throne. As Ritsuka and Mash travel to the Throne, Da Vinci reports that there are no Demon Gods detected there. She then asks Romani if Solomon is real or fake, and if he is a Heroic Spirit or something else. He answers that Solomon isn't fake, as the Reality Marble that is the Time Temple was created from Solomon's Magic Circuits. However, he then also states that Solomon shouldn't be considered "real" either, and ponders the possibility of him being controlled by someone. Mash wonders if Solomon became an Alter, but Romani rejects that notion, as Solomon had neither the will nor the emotions for either good or evil. Romani states his previous theory that Solomon may have had a human-like concept of good and evil, and became evil upon manifesting into a different class. However, upon reaching the Final Singularity, he rejected that theory because the inside of Solomon's body is not Solomon. He explains that after resurrecting Solomon's corpse, "Solomon" implanted the Demon Gods in preparation for the Incineration of Humanity. Afterwards, he created the Time Temple, which exists outside time, and there he waited until the year 2016. Ritsuka asks Romani what the inside of Solomon is, but he only answers they can ask "Solomon".

Upon arriving at "Solomon"'s throne room, Ritsuka and Mash see him sitting on his throne. He welcomes the pair, and asks them why they've come when the final calculations for the First Virtual Noble Phantasm, Ars Nova, are nearly complete. He explains he possesses three Noble Phantasms: the First is Ars Nova; Second is the Temple itself, Ars Paulina; Third is Ars Almadel Salomonis, the light bands. He then reveals the light bands were created from the energy gathered from incinerating humanity when he fractured history with his Singularities. Mash ask him what he is planning to that energy for, and why he needs so much energy. "Solomon" answers it is so he could achieve the ultimate position, and conquer death itself if humans will not. Ritsuka demands he reveal his true identity, to which he answer his body is Solomon's. "Solomon" then fights Ritsuka and Mash to kill Ritsuka since they serve as the anchor for the Heroic Spirits in the Singularity. After the fight, Mash notices a strange reading on his Spirit Origin, and Ritsuka notices one of his rings differs from the others. Impressed by the pair, "Solomon" decides to unveil his true form as Demon Gods cover the throne room. He reveals he is a Beast of Calamity, the first familiar created by Solomon that served as the foundation of human magecraft. He ruled alongside Solomon, and continued to exist as a primordial curse after Solomon's death. He then took control of Solomon's corpse, and incarnated himself through a summoning spell. With his true form unveiled, he identifies himself as Goetia, the Human Order Incineration Ritual and King of Demon Gods. .

Confirming he is Beast I, Goetia tells Ritsuka and Mash of how Solomon was granted omnipotence and omniscience by God. He continues Solomon possessed Clairvoyance capable of seeing past and future, and possessed all the knowledge in the world. Goetia saw everything that Solomon saw, and he witnessed many atrocities. Tired of all the suffering, he announces he no longer cares for humanity or the future, and states the planet was mistake due to life being finite. He then declares his plan to travel back to the genesis of the planet, and absorb all of its energy to create a new planet without death. He reveals he incinerated humanity to gather 3000 years worth of magical energy so he could travel back to the planet's genesis. Ritsuka and Mash then try to defeat him before he can activate Ars Almadel Salomonis. However, they are too late to stop the activation of his Third Noble Phantasm. Goetia then asks Mash to understand him, believing she too knows life is meaningless. He states humanity is worthless because humans can only live in fear of their inevitable death. He believes Mash shares his wish to create a planet without death. However, he has some uncertainty about his plan, and wishes for someone to understand him so he can be utterly sure of his plan. He reveals he knows Mash was created by humans with a limited lifespan, and offers to let her join him. He tells Ritsuka not to interfere with her decision, and states he feels he cannot leave her behind. Mash rejects him though, so he decides to launch Ars Almadel Salomonis at her and Ritsuka. Mash manages to protect Ritsuka with Lord Camelot, but the heat of Goetia's Noble Phantasm vaporizes her with only her shield remaining. Goetia declares that as long as the Time Temple exists, the seventy-two Demon Gods are immortal. Calling the struggles of Ritsuka and the Heroic Spirits meaningless, he prepares to launch Ars Almadel Salomonis again. However, he understand the anger Ritsuka must be feel towards him, so he'll allow them to punch him. But just they're about to do so, Romani arrives to their surprise. Goetia is also surprised by his arrival when he senses a familiar Spirit Origin. Romani removes his glove to reveal Solomon's tenth ring, which Solomon had sent to the future. He continues Marisbury Animusphere discovered and used it as a catalyst to summon Solomon in the Holy Grail War of 2004. The pair would eventually achieve victory in the war, and Solomon granted his wish to become human. However before all his power left him, he foresaw the Incineration of Humanity, but by then he was powerless to stop it. After thanking Ritsuka for their help, Romani returns to his original self, Solomon, having abandon his wish to the Holy Grail. Goetia mocks him as a mere Heroic Spirits, believing only the living Solomon could stop, and goes to kill Solomon. However, with all of his rings now present, Solomon activates the true Ars Nova to sacrifice his existence to remove Goetia's immortality. As he fades begins to disappear, Romani reveals Goetia was originally a spell created to watch over humanity. Goetia however turned away from that duty after witnessing the suffering and atrocities of humans. Rejecting Romani's belief that human life isn't merely suffering, Goetia goes to kill Ritsuka to remove the Heroic Spirits. Afterwards, he will activate Ars Almadel Salomonis before the union of the Demon Gods that comprise him completely collapses. Romani tells Ritsuka it is now up to them to defeat Goetia before finally disappearing.

With Solomon's sacrifice, the Time Temple begins to collapse, and the Demon Gods are thrown into disarray to either self-destruct or be destroyed by the Heroic Spirits. Goetia's body begins to crumble away due to the effects of Ars Nova destroying the union of the Demon Gods. He refuses to admit defeat even though only three Demon Gods remain, and attempts again to kill Ritsuka while asking why they fight. Ritsuka protects themselves with Mash's shield while waiting for the remaining Demon Gods to be destroyed. They then empower themselves with a Command Spell, and punch Goetia while answering they fought to live. Goetia realizes Ritsuka was just another human who feared death yet still fought to restore humanity. He then crumbles away while laughing at the absurdity of it all. With Goetia seemingly gone, Ritsuka hurries back to the Rayshift point before the Temple completely collapses. However, they're stopped by Goetia in human form. He admits his entire plan was thwarted the moment Solomon sacrificed himself with Ars Nova. He states his current form is all that remains of the seventy-two Demon Gods. He then decides to kill Ritsuka despite knowing it is meaningless decision he wouldn't have made before. But thanks to gaining mortality, he now understands human mentality, and thus wants to kill Ritsuka to protect his pride. After Ritsuka defeats him, Goetia disappears understanding human life is short yet fascinating. Ritsuka continues to hurry back to the Rayshift point, but the path to it collapses beneath them before they reach it. Meanwhile, Fou reveals to Mash that he's one of the Beasts, and that her death in the Temple doesn't count in reality. He then resurrect her by transferring his future as Beast IV to her to grant a normal human lifespan. Mash then arrives just in time to save Ritsuka, and together they return to Chaldea.

Shinjuku: Malignant Quarantined Demonic Realm
It occurred in Shinjuku, Tokyo, Japan, in A.D. 1999.

Setting
After escaping from the time temple following its collapse with Goetia's demise, Baal, one of four Demon Gods who escaped, sought revenge against Ritsuka Fujimaru, the human who thwarted the Human Order Incineration. Wandering for 3000 years, he eventually found himself in the culled timeline of Shinjuku in the year 1999. The city was filled with rampant crime of magical varieties, where evil consistently overcame good, forcing people to embrace the former just to survive. Baal soon discovered a way to fuse Phantoms with Heroic Spirits, seeing the former as valuable assets for his revenge. Fusion between Phantoms and Heroics Spirits was only possible due to the Counter Force being deactivated in Shinjuku with its separation from history. Baal would fuse Der Freischutz with James Moriarty, who manifested under the Archer class instead of the Caster as a result of the fusion. Seeking to finally thwart Sherlock Holmes, Moriarty forms an alliance with Baal, which would later be known as the Phantom Demon Alliance. He would advise a plan to destroy the planet, which would help achieve both of their respective goals. They plan to transform an asteroid into a magic bullet with Der Freischutz's powers, becoming possible only with its enhancement through the fusion with Moriarty. However, since crashing an asteroid into the planet wouldn't be enough to destroy the planet, they decide to construct a tower to act as a barrel to shoot the asteroid into the planet's core to destroy it. But in order to guarantee the asteroid is loaded into the barrel, Baal and Moriarty will turn it into Der Freischutz's seventh shot, said to kill an existence important to the shooter. To achieve this part of the plan, Moriarty devised to turn Ritsuka into said important existence, which Baal begrudgingly agreed with. Recalling Sherlock never goes full force unless against him, Moriarty erases his own memories, and creates a good personality for himself to trick his enemies. Baal does the same with his memories, and takes Moriarty's form, believing himself to be him. The two would go their separate ways, believing themselves to enemies while instinctively following their plan.

Acting as Moriarty, Baal gathers allies to him as well continuing his experiences of Phantom fusions. He fuses with Assassin (Fate/Grand Order - Yan Qing), fuses Christine Daaé into a Coloratura (human turned automaton) for Phantom of the Opera, and fuses  and  together to create a Phantom Servant called Hessian Lobo. With them becoming his allies, Baal takes control of Shinjuku with the aid of Phantom's Coloraturas and a private militia called the Hornets. He also has William Shakespeare captured and imprisoned inside Barrel Tower, which had begun construction. Forced against his will, Shakespeare summons Phantoms of his own characters, which are then fused into monsters. Edmond Dantès is summoned into the Singularity in order to rescue Shakespeare. EMIYA Alter is also summoned into the Singularity under contract to kill Baal, and joins the Alliance as it gave him a better chance to kill Baal. Sherlock rayshifts into Shinjuku to confirm his research about remnants of the Demon Gods returning despite the Human Order Incineration being thwarted. Baal also fights Artoria Alter and Jeanne Alter in their respective territories on separate occasions, grievously wounding the latter.

History
Ritsuka Fujimaru arrives in the era falling from the sky, with no Servants to save them. The Chaldea staff report any Servants that should've accompanied Ritsuka were repelled during rayshift, and they can't rayshift Ritsuka back until the era is fixed. Fortunately, a mysterious old man appears and saves Ritsuka. Landing on a nearby location, the old man, after checking their condition, shows Ritsuka the city they're now in is one of villainy; Mages, monsters, moving dolls, and pseudo army called the Hornets being such dangers. As well nearly all good nature people have died as only those of evil nature were able to survive long. The old man reveals the city to be Shinjuku, and shows the entire city is surrounded by a wall that only has an environment similar to the the other Singularities beyond it according to SHEBA. Leonardo da Vinci asks the old man about the tower being constructed to the west, to which he answers it is the enemy's headquarters. He reveals the tower doesn't connect to any road, and trying to enter it by jumping from rooftops would result in getting shot down by a Servant. The old man then introduces himself as Archer of Shinjuku as he fears revealing his True Name now may be dangerous. Down on the streets, Archer talks how anyone in the city can destroy the world now when previously such an act was prevented, which makes da Vinci suspect his villainous identity but she draws a blank. Archer then stops Ritsuka from getting caught a wire net tossed by some thugs. When the thugs go to confront Ritsuka and Archer, da Vinci see they possess magic to her and Mash Kyrielight's surprise. Archer explains they're Spellcasters who embraced their evil to survive in Shinjuku as good will only be oppressed or killed. The thugs then go to kill Ritsuka and Archer, hoping to sell their corpses to a necromancer. Back in Chaldea, after the thugs are defeated, da Vinci is unnerved she can't figured out Archer's True Name despite her genius. While agreeing with Mash's suggestion that Archer is disguising both his True Name and class, da Vinci believes it may also the possibility of Servant misunderstanding its own class. In this case, it's a Caster misunderstanding itself as a Archer. Da Vinci and Mash are further unnerved by Archer's fighting style as it uses bullets, which doesn't apply to who she suspects his identity to be. She decides they should continue investigating Archer while keeping it a secret from Ritsuka. Back in Shinjuku, Ritsuka believes Archer was summoned into the Singularity to fight for justice, which he suspects to be true. Then, after hearing that Ritsuka's answer of wanting to trust him, Archer decides to fight with them to earn their trust, and out of a common interest to stop the evil in Shinjuku.

After saving Ritsuka from a bomb disguised as a crying baby, Archer explains the city is filled with such traps. Suddenly, a group of enemies, which Archer calls Coloratura, approaches, and he has himself and Ritsuka hide themselves. Archer explains Coloraturas are Christine Daaé's marionettes, which patrol and massacre people whilst singing. After witnessing a Coloratura kill a man with no corpse leftover, Archer wonders if they use corpses as materials. Ritsuka attempts to save a wounded thug who they encountered earlier, but Archer warns them it's a trap by the Coloratura. After the thug is killed, Ritsuka and Archer attempt to sneak around the Coloratura without making any noise as they possess sharp ears. Unfortunately, Archer steps on some trash left on the street, which gets the attention of the Coloraturas. After nine of them are destroyed, the remaining two Coloraturas remain back, so Archer asks Mash to set an escape route for him and Ritsuka. However, the controller of the Coloraturas approaches them while Mash plots out of their escape route. The controller is revealed to be the Phantom of the Opera with a special Coloratura he identifies as Christine, who demands Ritsuka and Archer's blood, and prepares to attack. After Mash establishes an escape route, Moriarty destroys a nearby gas station to distract Phantom and Christine while he and Ritsuka can escape. Escaping to a highway, Archer explains all Servants who've fallen to evil in Shinjuku have separated into their own respective territories, which the highway happens to be one of them. Ritsuka and Archer are then chased after by giant wolf ridden by a headless person, which is targeting Ritsuka. As he runs while carrying Ritsuka, Archer explains the wolf is a Phantom, an existence born of fiction not strong enough to become a Heroic Spirit, and thus cannot be summoned as a Servant under normal circumstances. The wolf eventually catches up with the pair, so they're forced to fight it, which Archer identifies as Rider of Shinjuku. Unfortunately, Archer proves too weak of a match for the wolf, so he asks Ritsuka to escape by car to Shinjuku Station, where they'll meet up later. As Archer fights the wolf, a smokescreen appears when Artoria Alter suddenly arrives on a motorcycle. She then helps Ritsuka escape while Archer continues holding off the wolf.

After escaping, Artoria Alter brings Ritsuka to her hideout, the basement of a burger shop. There she reveals she fought Archer before, not believing his current good nature after hearing it from Ritsuka. She also explains Archer's strength and magical energy were exceptional at that time. Telling Ritsuka to be wary of Archer, Artoria reveals Archer and Rider are part of an alliance of four Servants that controls Shinjuku, the Phantom Demon Alliance. Suspecting them to be the Singularity's source, she investigated them when she encountered Edmond Dantès , who told her to help Rtisuka. However, Artoria Alter expresses concern for Edmond given his apparent lack of stength to even explore Shinjuku on his own to complete his task. Da Vinci wonders if something drained Edmond of his strength, but the lack of information makes her switch back to the topic of the Phantom Demon Alliance. Artoria Alter states defeating the alliance will require thorough strategy and great strength, believing Archer will join the effort. Warning Ritsuka to be careful of the city and Archer, she decides to help them search for Archer at Shinjuku Station tomorrow. The next morning, Ritsuka and Artoria Alter head to Shinjuku Station, which had turned into a labyrinth. However, while exploring the station, Artoria Alter becomes worried that the station's usual thugs are gone without a little trace of them being there. She suspects someone had cleaned up the scene to prevent anyone from discovering what happened to the thugs to prevent any witnesses from running. Realizing it's a trap, the pair are supported by Hornet soldiers. After defeating them, they hear fighting more Hornets, and asking for assistance. Arriving to defeat the remaining Hornets, Artoria Alter demands to known who Archer is and why he saved Ritsuka. Archer answers that he did instinctively to his confusion, though Ritsuka believes him to be a Hero of Justice. Artoria Alter then asks him of his connection to the Archer she fought before, demanding once again to know his identity. Archer reveals that while sharing the same appearance of the Archer Artoria Alter fought before, he had his True Name solen, and lost most of his power. Da Vinci wonders if he was split into good and evil, which makes Archer suspect himself to the good version. He speculates he had banished his good self to become the perfect villain as his conscience was disturbing his plan. Archer then decides to join Ritsuka and Artoria Alter in the hopes of regaining his True Name. Then, after explaining his deduction of Artoria Alter's identity, he goes with her and Ritsuka back to the hideout.

The next morning at the hideout, the group are alerted by a sudden phone call. Answering the phone, Ritsuka learns from Edmond that Alliance soldiers lead by EMIYA Alter are heading for Jeanne Alter's hideout. She remained neutral since her summoning, declaring to burn and kill any trespassing her territory. The Alliance soldiers are heading to kill her before she can become Ritsuka's ally, though Edmond doubts trusting her. Ritsuka decides to help Jeanne Alter regardless, so Edmond tells them to head to Shinjuku Gyoen, where she's located. After being told of the call, Archer reveals he was attacked by Jeanne Alter when he sneaked into her territory. Meanwhile, Jeanne Alter fights EMIYA Alter, and uses La Grondement Du Haine to force his retreat. Exerting herself with that attack, she is eventually found the group, and argues with Artoria Alter about her having a Master now. Learning said Master is Rtisuka, Jeanne Alter tries to convince them to make her their Servant, believing she can fight better than Artoria Alter and Archer. After defeating some thugs, Jeanne Alter and Artoria Alter argue about who Mash is subordinate to, with Artoria Alter arguing Mash is her subordiante since Galahad is possessing her. They stop arguing however when Jeanne Alter finally regonizes Archer, who apologizes her trespassing into her territory. But, she states Archer had severely wounded her previously, forcing her to escape into the subway while being pursued. As Jeanne Alter prepares to incinerate him, Archer tries to convince her the Archer who wounded was his evil self while he's the good Archer. However, learning Archer saved Ritsuka, Jeanne Alter decides to join the group despite not trusting Archer. Then, upon seeing Artoria Alter's clothes, she goes to collapsed boutique under the excuse she saw something suspicious. While waiting for her to return, the group attacked by a group of thugs and their so-called "Super Chimeras" After the thugs and one of the Super Chimeras are killed, the ghost of a thug commands the other Super Chimera to kill the group. However, Rider arrives and kills both it and the thug's ghost. Artoria Alter tells Ritsuka to carefully escape as the area is now Rider's territory, but Rider takes notices of Ritsuka though and prepares to attack. Jeanne Alter returns and unleashes La Grondement Du Haine on it on Archer's signal. Unfortunately the flames from Jeanne Alter's Noble Phantasm prevent the group from escaping, so they're forced to fight Rider, who can't escape either as Archer planned. After forcing Rider to retreat, Archer reveals the wolf is the master not the headless man, who is merely an urban legend meant only to frighten people. The wolf differs though as he ate people out of its resentment for humans. Ritsuka realizes the wolf to be, the wolf from 's book that became feared for its intelligence, and died resenting humans after falling into a trap involving its dead mate, Blanca. Archer decides that with Rider out of the picture for time being, it's now the perfect opportunity to take out the Phantom, the Berserker of Shinjuku. Returning to the hideout, Ritsuka answers another phone call from Edmond, who congratulates them for their victory. He reveals the tower being constructed on the former site of the Tokyo Metropolitan Government Office is called Barrel Tower. He continues the evil Archer is the leader of the Phantom Demon Alliance, whose plan is to destroy the earth. Edmond tells Ritsuka they need to defeat the members of the Alliance before taking on Barrel Tower. After Ritsuka tells him they're going after the Phantom, Edmond tells them that the Phantom's base of operations is around Kabukicho. He then ends the call after telling Ritsuka to not trust Archer too much.

After Ritsuka relays the information to the others, Archer states their current numbers are not sufficient enough to win against the Phantom. He continues that about 200 Coloraturas are stationed at Kabukicho while another 100 regularly patrol Shinjuku. If the group were to attack now it'd result in a fight against 200 coloratura that'll end with either the Servants dead, or more likely Ritsuka dead. Archer reveals the Coloraturas are listening to Christine's song on 24-hour loop coming the speakers as they wander Kabukicho, applauding every-time the song finishes. He also warns it's easy to get lost in Kabukicho as many of the building look the same, and one may find themselves ambushed the patrolling Coloraturas. When Atoria Alter and Jeanne Alter say they both destroyed several Coloraturas, Archer reveals those numbers return to being hundred, and the Coloraturas regularly abduct people for some purpose. With a frontal assault out of the question, Ritsuka suggests long ranged sniping, but Archer replies he might being to kill Christine. Artoria Alter suggests using Excalibur Morgan to destroy everything, but Archer claims the Phantom and the Coloraturas would survive as Shinjuku is now brimming with an unbelievable amount of magical energy. Archer then asks the others to bring him a Coloratura intact, which he'll use to observe Kabakicho through it. Ritsuka, Artoria Alter, and Jeanne Alter then go out to find a Coloratura while Archer goes to purchase materials for the modification. Later, Ritsuka, Artoria Alter, and Jeanne Alter come across a Coloratura abducting a man, and they move to capture it. With the Coloratura captured and the man saved, the group return to the hideout. There it is reveals the Coloraturas are constructed from humans, with their flesh and nerves being placed into the dolls. After stating the humans once turned Coloraturas can't be saved, Archer reveals he rigged the Coloratura with a bomb. Said Coloratura will be placed back with the others when they return to Kabukicho at their regular intervals, and then its bomb will triggered. The explosion will cause confusion among the Coloraturas, which the group will use as an opportunity to kill Phantom and Christine. After Archer finishes rigging the Coloratura, and gives the detonator to Ritsuka, the group head for Kabukicho. Placing the rigged Coloratura with the others, Archer orders Artoria Alter and Jeanne Alter to take their positions. Ten minutes later, Ritsuka prepares to detonates the bomb, but Archer pushes it first after Ritsuka's determination. The resulting explosion scatte the Coloraturas, and Artoria Alter and Jeanne Alter move in to fight them. Meanwhile after destroying several Coloraturas, Ritsuka and Archer encounter Phantom and Christine. It is revealed that Christine was summoned with a severely lacking Saint Graph, so Phantom placed her into a doll. Sickened by Phantom's actions, Ritsuka and Archer fight Phantom and Christine. After they're defeated, Christine asks Phantom if she was only summoned to sing, which he confirms before she disappears. However, before he could reveal something about Archer, Phantom is killed by EMIYA Alter, who knows Archer's True Name. Mash calls Artoria Alter and Jeanne Alter to help Ritsuka and Archer, but they're busy dealing with the still active Coloraturas. Ritsuka and Archer prepare to fight EMIYA Alter, but Cursed Arm Hassan arrives and convinces him to retreat. After Artoria Alter and Jeanne Alter rendezvous with Ritsuka, Archer, and Cursed Arm, the group escape Kabukicho.

Returning to the hideout, Ritsuka, Archer, and Cursed Arm celebrate their victory. After Archer collapses drunk, Cursed Arm claims the Singularity of Shinjuku will soon disappear since Ritsuka already resolved the Human Order Incineration. Da Vinci warns though the Singularity manifested after the Human Order Incineration was resolved, and they haven't a clue what the enemy's goal is. However, Cursed Arm reveals the Phantom Demon Alliance's goal is to destroy the planet, but da Vinci states such a task is impossible even with an Anti-Planet Noble Phantasm. Cursed Arm interrupts her, claiming to sense an intruder nearby despite Mash not sensing anything. Claming it to be an Assassin, Cursed Arm takes Ritsuka with him to find the intruder. Once outside though, he reveals himself to be Assassin of Shinjuku, a member of the Phantom Demon Alliance, impersonating Cursed Arm perfectly through his transformation. He takes Ritsuka hostage, but Artoria Alter and Jeanne Alter arrive to stop him. Assassin dodges both of their attacks, and makes his escape as Artoria Alter chases him on her motorcycle with Jeanne Alter following. Eventually, she shortens the distance, so Assassin sends some Hornets to attack her. After they're killed, Assassin sends out a spriggan he claims to be King Lear. Artoria Alter eventually finishes it off with Excalibur Morgan, but her exhaustion gives Assassin a chance to escape as Ritsuka passes out.

Ritsuka later wakes up in Barrel Tower, the Phantom Demon Alliance's headquarters, having taken there by Assassin. There they meet the Alliance's leader, the evil Archer who reveals he used the Holy Grail to separate himself from his virtuous emotions. Deciding that killing Ritsuka would be fruitless since Chaldea would send another, evil Archer tries to make a deal with them. The deal is that he'll let Ritsuka to Chaldea in exchange for Chaldea not interfering with him. After evil Archer leaves, Ritsuka meets William Shakespeare whose been made prisoner by the Alliance. Assassin explains that they've been forcing Shakespeare to create monsters based off his works. After Assassin leaves, Shakespeare warns Ritsuka that escape will be difficult for them as the tower is patrolled by both Hornets and mass produced King Lears. He then suggests that the good Archer knew Cursed Arm was Assassin of Shinjuku in disguise, and let him kidnap Ritsuka. After Shakespeare points out the possibility, Ritsuka takes out a letter from Archer that reads they'll be saved and learn everything from their savior. Edmond then appears, reveals himself to be the help sent by Archer. Apologizing to Shakespeare that he can't save him right now, Edmond prepares to escape with Ritsuka when the alarm is triggered. Escaping to a rooftop after dealing with enemy forces, he tells Ritsuka not contact Chaldea now as their communications may be tracked by the enemy. Ritsuka then realizes Edmond isn't Edmond, which he confirms and reveals himself to be Sherlock Holmes. Sherlock reveals he was researching the probability of the resurgence of Singularities after the Human Order is restored. He continues that TRIHERMES warned powers from the distorted history would be leftover, strong enough to disrupt the correct history. Normally, the Counter Force would prevent them from manifesting, but history shifting to its restoration state created a gap for said powers to return. According to TRIHERMES' calculations, there is the possibility that one of those powers would appear in Shinjuku. Moving on from the subject, Sherlock reveals Archer to be his nemesis, James Moriarty. Returning down to the streets, he states he and Moriarty should have sensed each other when he entered Shinjuku. However, the good Moriarty is too weak to do that, so he had realize to Sherlock's presence by guessing his own name. Sherlock then reveals he had Watson depict Moriarty vaguely as impossible out of fear what impact his evil charisma would have on the world. He then explains the evil Moriarty got the power and the True Name when he split from the good Moriarty. As he becomes troubled by a good Moriarty, Sherlock reveals Moriarty let Ritsuka be kidnapped. Suggesting Moriarty should've deduced his presence by now, Sherlock says he'll reveal the true purpose of destroying planet before the rest of the group. A celebrity and some thugs then come to harasss the pair for food, but they're defeat by Sherlock in his Edmond disguise. Still in disguise, he then purchases twenty of some item from a merchant named Kaburagi. After the purchase is made, Ritsuka and Sherlock reunite with the others.

Returning the hideout, Sherlock introduces himself to the others, and Moriarty explains how Artoria Alter and Jeanne Alter beat him for letting Ritsuka get kidnapped. Having regained his memory, Moriarty reveals his True Name, and that he manifested as a Servant after being fused with a Phantom. Sherlock then explains how the Alliance's goal of destroying the planet is possible without utilizing outside forces by doing what Thomas Edison and the Lion King tried to do. After Mash explains Edison and the Lion King's plans to isolate their respective timelines, da Vinci and Ritsuka realize the Singularity is in a culled timeline. This means the Counter Force's protection is no longer activate, so the planet's destruction becomes possible. Despite being told it'll have no adverse effect on history, Ritsuka decides to save Shinjuku regardless. Sherlock then reveals the method by which the evil Moriarty will use to destroy the planet. The plan is to have evil Moriarty use the powers of the Phantom he's fused with,, to load a meteorite into Barrel Tower, then fire into the planet's core as a magic bullet to destroy it. Deciding they need to eliminate Assassin first, Sherlock has Moriarty formulate a plan for the group. Overlooking the information Sherlock gave him about Assassin, Moriarty orders the others to get some clothes. After defeating some thugs and their hacked Coloraturas, Ritsuka, Artoria Alter, and Jeanne Alter change clothes. Changing into dresses, the trio enter a party hosted by Assassin while Sherlock and Moriarty oversee the situation through the transceivers they gave them. After Artoria Alter sends embarrassing photos of Ritsuka to Mash and dances with then, Assassin appears before the guests disguised as Artoria Alter. He eventually takes notices of her, and orders the Hornets to attack. Joined by Moriarty, the group defeat the Hornets followed by Romeo and Juliet. More Hornets then appears, with Assassin being disguised as one of then. Ritsuka removes their dress to shock Assassin into revealing himself as part of Moriarty's plan. Assassin identifies himself as Yan Qing, and fights the group. Sensing that he's going to lose, Yan Qing activates a bomb under the building to collapse it, prompting the group to escape. A thug, a Hornet, and a civilian then raise from the building's rubble, but Moriarty and Sherlock both deduce the civilian is actually Yan Qing. Fatally shot by Moriarty, Yan Qing reveals his fusion with caused his own personality to become muddled before disappearing. With Yan Qing now dead, the group prepare to return to the hideout when they're found by the newly recovered Rider.

Confronted by Rider, the group see it has been fused with another Phantom, the, as indicate by its invisibility. After Rider unveils itself, Sherlock deduces the headless man riding Lobo to be the Hessian from. Rider then under goes a class change into Avenger, and instantly targets Ritsuka as they're the human around. Unable to defeat it, the group decide who'll stay behind to hold Avenger while the rest escape. Jeanne Alter takes the task upon himself, so the others can escape. As she fights off Avenger, Jeanne Alter declares to it that it's hatred will never be satisfied, so she must kill it. Despite her valiant efforts, she is left fatally wounded by Avenger's numerous bites. Meanwhile, back at the hideout, the group formulate a plan to defeat Avenger. Knowing it'll flee if placed in a disadvantageous situation, the group decide they need to trap Avenger. Recalling Lobo died after falling for a trap using his dead mate, Blanca, the group need those to defeat Avenger as they're its conceptual weakness. While they'll be able construct a leg trap from the materials around Shinjuku, the issue is that no white wolf like Blanca resides in the city to lure Lobo. However, upon seeing Artoria Alter's dog, Cavall II, the group decide to use him as bait given his white fur. Unwilling to let Cavall II be used a bait at first, Artoria Alter eventually reluctantly agrees when Cavall II gives his consent according to Fou, Moriarty, and Sherlock. Later, the group set up traps as Ritsuka and Artoria Alter on her motorcycle wait for Hessian Lobo to arrive. When it arrives, the pair lead it to a couple of trap, but it easily avoids them. However, Hessian Lobo is caught by the third trap when it stops upon seeing Cavall II. Taking advantage of the situation, Ritsuka and Artoria Alter fight Hessian Lobo before it can break free. However, before Artoria Alter can finish it off, Hessian blocks her attack after separating from Lobo. Hessian then throws his weapons away, and tries to protect Lobo, who bites off his foreleg and flees. Artoria Alter tries to give chase, but Sherlock stops her as he knows Lobo will die soon. After Hessian disappear, the group realize Lobo only wanted to go home but that desire became clouded by his vengeance. Meanwhile, as he wanders Shinjuku, Lobo finally remembers his desire to return home, and passes away upom encountering Cavall II again.

Back at the hideout, Moriarty states EMIYA Alter is standing guard in front of Barrel Tower accompanied by more than 200 Hornets. Sherlock states they'll have to fight them head on as he doesn't when the evil Moriarty will draw the meteoric into Barrel Tower. Da Vinci then reveals a meteorite did fall to Japan in 1999 (the Singularity's year), but its gross weight of 136 grams is too small to destroy the planet. However, Sherlock reveals a C-Type asteroid with an average diameter of 500 meters called was discovered and observed that same year, which he believes the evil Moriarty will use as his magic bullet. He then reveals Phantoms, while too weak to summoned as Servant, can have their respective abilities greatly enhanced when fused with Heroic Spirits. Da Vinci realizes cause Der Freischutz to consider celestial objects being under the concept of magic bullet. Moriarty explains her that fusion between Heroic Spirits and Phantoms is only possible in Shinjuku, which she agrees as the concept of Heroic Spirits fusing with each other is inherently impossible. Returning to topic of EMIYA Alter and his Hornets, Moriarty sends pictures of them to da Vinci. She lay out information on their formation and their weapons, which the same ones used to counter large Demonic Beasts. Realizing she's being targeted based on the weaponry, Artoria decides she can't use her motorcycle to charge in and disturb enemy ranks. While agreeing with a more defensible approach, she says they'll need a way to quickly close the gaps, claiming it's nigh impossible to breakthrough with EMIYA Alter present. When Artoria Alter says they'll need an impractical method, Mash recalls her and Ritsuka being launched by Arash during Camelot. Following this method, Moriarty builds a makeshift launcher to launch Ritsuka and Artoria Alter into enemy ranks after they're tricked by a decoy matching her Saint Graph. As Artoria Alter fights EMIYA Alter, Coloraturas hacked by Sherlock earlier appear and attack the Hornets. Moriarty then throws down a smokescreen, which Artoria Alter uses to quickly switch a Hornet with him disguised as one. However, EMIYA Alter sees through the ruse, but nonetheless lets Moriarty pass. He orders his men to continue fighting the Coloraturas, and to blow the entrance to the tower once he's followed the group inside.

Inside the tower, the group fight through a multitude of enemies as they ascend the tower. Mash and da Vinci later detect EMIYA Alter's presence behind the group, so Artoria Alter offers to hold him back while Ritsuka and Moriarty go on ahead. But, EMIYA Alter doesn't move, so the group continue their ascent when they encounter. After defeating him, the group continue to ascend the tower, defeating more enemies along the way. Reaching the top floor, they're greeted by the evil Moriarty whose been expecting them. He then declares he's been waiting 3000 years for this moment to his confusion. Dismissing that, evil Moriarty announces Bennu is already being drawn to the tower by the power of Der Freischutz before fighting the group. However after his disappearance, a Demon God manifests in humanoid form to shock of Ritsuka, Mash, and da Vinci. Having regained his memory, the Demon God reveals he's waiting for 3000 years just to kill Ritsuka. Despite knowing its a grudge, he found it unforgivable that Goetia's plan was overthrown, not by a Heroic Spirit or a similar existence, but by Ritsuka, a mere human. The Demon God then reveals that the destruction of the planet is for express purpose of killing Ritsuka. Sherlock realizes the Demon God had escaped the time temple to enact his plan while waiting for 3000 years. He reveals that Charles Babbage, as a subordinate to the Demon Gods, had figured out they had contingency in place in case the Human Order Incineration plan failed. The Demon God states after waiting for 3000 years, he found a way to fuse of Phantoms and Heroic Spirits, the former of which he found tremendous value in for his revenge. He then reveals his name to be Baal, and Sherlock asks him how much he and Moriarty were involved. Baal doesn't answer the question instead letting Moriarty reveal they're partners as he pierces Sherlock. Realizing Moriarty took a incredible gamble to win against him, Sherlock implores Artoria Alter to kill him. However, his request come too late as he is absorbed into Moriarty to gain his power. Seeing the group is confused by his sudden betrayal, he decides to explain himself given Sherlock is gone. He explains that since Shinjuku is in a culled timeline, it became possible to fuse Phantoms with Heroic Spirits. He formed an alliance with Baal to achieve their respective goal; Baal to kill Ritsuka and Moriarty to surpass Sherlock. Moriarty continues that as long as he exists as himself, he'll never win against Sherlock regardless of his plans. This unwritten rule between them continued even after they became Heroic Spirtis, comparing it to the Counter Force. Recalling Sherlock only uses his full potential when against him, Moriarty decided to join his side to lower his guard. He reveals he intentionally erased his memory and evil personality to create a good persona. Baal did the same thing, believing himself to be the evil Moriarty while Moriarty believed himself to be the good one. Suddenly, EMIYA Alter appears and shoots Baal, and reveals he was contracted to kill Baal. Knowing they'll be no repercussion regardless of the destruction created in this culled timeline, he decided to join the Phantom Demon Alliance as they had a greater probability of achieving his goal. Accepting his help, Ritsuka lets him fight Baal while they and Artoria Alter fight Moriarty. Despite his defeat, Baal declares his revenge has already been fulfilled, and thanks Moriarty for being his ally until the end. Baal then disappears after declaring Ritsuka will absolutely die.

Suddenly, Bennu appears in the sky above Shinjuku as it became the magic bullet the moment Moriarty was determined to die. Moriarty reveals the six shots of Der Freischutz aren't enough turn the asteroid into a magic bullet. Mash then realizes the moment Moriarty protected Ritsuka with his life, they became an important existence. So adhering to the rules of Der Freischutz, the seventh shot, Bennu, will head for the tower as Ritsuka, the important existence, is there. Artoria Alter realizes getting Ritsuka into the tower was part of Moriarty, which he confirms. Revealing he became good to make Ritsuka vulnerable, Moriarty announces Bennu will be loaded into the tower in five minutes. Artoria Alter takes EMIYA Alter intercept Bennu, believing Moriarty won't harm Ritsuka now. Da Vinci asks the Chaldea staff to force the rayshift, but they report the seventh bullet strengthened the Singularity's causality, preventing them from rayshifting Ritsuka back. Asked by Ritsuka if he regrets his actions, Moriarity dodges an attack both he and Ritsuka sensed. The source of the attack is revealed to be the real Edmond. Moriarty then dodges an attack from Jeanne Alter, who survived her fight with Hessian Lobo by escaping into the sewers following Sherlock's advice to her. Jeanne Alter reveals that she and Edmond brought reinforcements, who are revealed to be Hans Christian Andersen and Shakespeare, whose rescue was why Edmond was summoned. Deducing Moriarty absorbed Sherlock to remain undefeated, Shakespeare and Anderen combine Märchen Meines Lebens and First Folio to summon the Great Detectives, a cavalcade of Phantom detectives. Although they cannot help physically, the detectives will give their strength to Ritsuka. Moriarty scoffs at the notion of detectives other than Sherlock besting him, but nonetheless uses the Grail to give himself magical energy equal to Demon God. With only three minutes before Bennu arrives, the group commence their final battle against Moriarty. Struggling against the group, Moriarty uses the Grail on himself once again. However, the detectives use this opportunity to grant Ritsuka their Noble Phantasm, Critical Word. Ritsuka uses Critical Word to unveil Moriarty as the culprit, which results in strength being taking away. While accepting he lost, Moriarty is nonetheless confused why he lost as his calculations favored him being victorious. Ritsuka helps understand that that he was actually holding back as he had thought of them as a important person he couldn't erase. Meanwhile, on the rooftop, EMIYA Alter uses Unlimited Lost Works to break Bennu apart from the inside followed by Artoria Alter destroying the fragments with Excalibur Morgan. With Bennu destroyed, the Chaldea staff announce they can now rayshift Ritsuka back. Accepting his and Baal's plan failed, Moriarty apologizes to Ritsuka for using their good nature against them. He tells Ritsuka to believe in the good Moriarty they knew, and makes a challenge to the detecives before they disappear. Asking that Ritsuka to remember to summon him, Moriarty bids farewell to them and disappears. After Shakespeare, Andersen, and Edmon disappear, EMIYA Alter tells Ritsuka and Jeanne Alter that Artoria Alter went somewhere before disappearing. Ritsuka and Jeanne Alter both realizes that Artoria Alter went to say her goodbyes to Cavall II before she disappears. After EMIYA Alter disappears, Jeanne Alter cuts off communications with Mash, and asks Ritsuka for a dance. Once they finish dancing, she disappears after saying goodbye, and Ritsuka returns to Chaldea. There Ritsuka, Mash, and da Vinci learn from a recovering Sherlock that Baal was only one of four Demon Gods who escaped the time temple.

SE.RA.PH. - Deep-Sea Cyber-Nirvana
SE.RA.PH. - Deep-Sea Cyber-Nirvana (深海電脳楽土 SE.RA.PH) was a special Singularity which emerged in the aftermath of the Human Order Incineration Incident. Originating on Chaldea's Seraphix facility in the North Sea, it occurred in the, supposedly in 2030 A.D.

Setting
After escaping the Time Temple along with three other Demon Gods, Zepar sought to help humanity realize their mental potential. However because he lost his body, he needed to seek refuse somewhere to regain his strength. He eventually found Seraphix, an oil rig secretly containing a planetarium called Celestial Body Simulator, System Animusphere, which was used to investigate leylines. He eventually found Kiara Sessyoin, a therapist who worked at Seraphix, and possessed her to avoid Chaldea's detection. He then used her to eventually effectively gain control of Seraphix. Using his knowledge of parallel worlds, Zepar discovered another version of Kiara, one who usurped control of the Moon Cell on the far side of the Moon. Impressed by her, he linked the two Kiara together, and used her body to convert Seraphix into SE.RA.PH and give it form. Afterwards though, Kiara plunged the Seraphix staff into mass hysteria to Zepar's disgust. She then seduced the personnel to open the planterium, where she placed 128 Master candidates in the Coffins found there to summon 128 Servants, which killed them. As well BB, Meltlilith, and Passionlip were salvage from Kiara, as she had absorbed them in the Moon world, to serve her. Jealous of the delight she felt from Zepar's memories, Kiara sought to use SE.RA.PH to become a Beast. Zepar realized at this point that he lost control of Kiara's body, and he was forced to reside only in her pinky finger. Eventually though he was forcibly expelled, and quickly disappeared. Kiara then enacted her plan to descend SE.RA.PH down into Earth's core so she may fuse with the planet. She infected Meltlilith and Passionlip with parts of her, Karmaphage, to turn them into Sentinels to serve as SE.RA.PH's self-defense mechanisms. She also ordered BB to begin the Holy Grail War while continuing to manage SE.RA.PH. At some point though, the Moon Cell sent a copy of the original BB to Seraphix on a one way mission to prevent Kiara's transformation into Beast. She then switched places with the other BB as manager of SE.RA.PH while the other hid at its bottom.

BB recreated the Moon Holy Grail War, but compared to its original more organized battle royale counterpart, this one turned into a massacre. The Servants succumbed to their desires, and began to commit several atrocities. One particular Servant by the name of Suzuka Gozen was turned into a Sentinel by BB, hoping to win the Grail War for her Master, not knowing they were already dead. Meanwhile, the corpses of the Masters inside the still active Coffins were used as biological circuits to continuously summon Servants. Eventually Meltlilith and Passionlip decided to rebel against Kiara, and became the Servants of a version of Ritsuka. They eventually won the Holy Grail War, and fought Kiara at the planetarium. They lost though, and BB's time leap failed due to Meltlilith and Passionlip still being Sentinel. Meltlilith's arms were torn apart, and Ritsuka was killed for her transgression. Passionlip then used Virgin Laser - Palladion to launch Meltlilith upwards at the speed needed for time travel. Meltlilith vowed to redo everything so she can help Ritsuka free the Sentinels from Kiara's influence. She then met a past version of herself at the chapel, and shared her memories with her. The past Meltlilith then committed suicide without hesitation to prevent Kiara from realizing there were two Meltlilith.

History
Nero Claudius, Tamamo no Mae, and EMIYA are talking with Ritsuka when Mash Kyrielight announces over the intercom that Chaldea has achieved its regular report from the Seraphix Offshore Oil Rig. She urges any free staff members to come to the command room if they wish contact their friends at Seraphix, as the contact window is half a day, and the next one will be in three months. Nero asks what Seraphix, and Tamamo answers its a Chaldean outpost which provides Chaldea with resources that was owned by Marisbury Animusphere. Curious about Seraphix, Ritsuka goes to the command room with Nero, Tamamo, and EMIYA following them. There they meet Mash and Leonardo da Vinci whose there to ensure everything is fine with Seraphix since Chaldea's current year budget depends on Seraphix's condition, as per her duty as acting director. Ritsuka asks about Seraphix, to which Mash explains its a North Sea offshore oil rig owned by the Animusphere Family. She continues Seraphix is built on a semi-suppressible platform with a crew of at least one hundred. Despite its distance from Chaldea, it is still one of Chaldea's most lucrative revenue streams. Neither Mash and Da Vinci ever visited Seraphix though, so only the original Chaldean staff would know more before their deaths in Lev Lainur Flauros's attack. Da Vinci explains the Chaldean staff members who remain in contact with Seraphix now are those who become friends through repeated transmissions over the last few years. A comm officer prepares to establish a video feed with Seraphix, but despite video and audio feeds being active, no one seeing or hearing anything. Da Vinci assumes its glitch when a quiet and garbled message is heard by Mash. At Mash's request, comm officer increases the message's volume to maximum. It's revealed to be an SOS message saying everyone is being converted into data. The connection with Seraphix is then abruptly cut, so Da Vinci authorizes the use of Sheba to observe Seraphix. However, a staff member reports that Seraphix seemingly no longer exists, with no signs of a Singularity. The comm officer then reports the SOS message originate from a zone they can't detect. Suddenly they receive another transmission with it being audio only at first before quickly establishing video. The messenger is shown to be a mysterious girl, but the comm officer is unable to establish the transmission's origins. The staff then quickly realize the girl had usurp control of the facility from them. She reveals herself to be an AI, and that her name is BB. BB then reveals Seraphix no longer exists in the current time period, and tells Chaldea to check the Mariana Trench in 2030 A.D. The staff confirm Seraphix's location, revealing its currently 200 meters before the surface along with the existence of a Singularity. BB warns Chaldea to save Seraphix's staff before the oil rig sinks down to 10,000 meters while also dealing with the Singularity manifesting there. Nero urges Da Vinci to rayshift her, Ritsuka, Tamamo, and EMIYA to Seraphix. However, Da Vinci explains rayshifting to the future is impossible, but she quickly realizes BB can verify Ritsuka and others' existence as 2030 is BB's present. BB warns Seraphix will reach the bottom of the trench in a few hours, at which point it'll be destroyed by the water pressure. Ritsuka, Nero, Tamamo, and EMIYA then rayshift to Seraphix. However BB hacks the rayshift to separate the group to random locations in the facility.

Ritsuka arrived in a strange locale when they're contacted by BB. She explains to them that they've been plunged into a Holy Grail War, a battle to the death between 128 Masters. She admits though she tricked the Masters into believing there was a world ending threat when she was just using them to kill time. She then explains to Ritsuka that they're in Seraphix but it's been digitized into Pseudo-Spiritrons. She continues information lifeforms and organic lifeforms can interact with each other in this space for long as there's intellectual activity. As well any experience, knowledge, and power sources Ritsuka attains will be carried over when they return to the physical world. Any event they engage in SE.RA.PH will also have the same effect on them as in reality. BB refuses to reveal why Seraphix was digitized, but tells Ritsuka they're at what used to be Seraphix's front gate. She tells them to discovery the mystery of the digitization before SE.RA.PH sinks to the bottom of the trench while surving through the Grail War. After BB ceases communcations, Ritsuka prepares to go find Nero, Tamamo, and EMIYA. However they're by attacked a girl, barely dodging her sword. She attacks Ritsuka again, but her attack is blocked by another girl. The girl reveals the female swordsman to be Suzuka Gozen, and offers to save Ritsuka if they form a contract with her. She introduces herself as Meltlilith, and Ritsuka promptly forms a contract with her. She then fights Suzuka, but her attacks are reduced by 90% by Suzuka's karmaphage. Suzuka boasts karmaphage is the mark of a true Sentinel, a position she wouldn't have gotten if Meltilith didn't abandon it. She continues she will kill every other Servant, and use the Holy Grail to transform her Spirit Origin into the Demon King's daughter. Meltilith mocks her, and reveals her attacks are filled with deadly viruses. Seeing she's at a disadvantage, Suzuka retreats. Meltilith decides to explain the basics to Ritsuka as they travel. She assumes they're a failed Master who couldn't contract with a decent Servant. She also explains she is a High-Servant, an amalgamation of goddesses. She then decides they should enter the facility from the main oil deck cable area, given the front gate is completely digitized. She warns Ritsuka that they'll eventually be disintegrated if they stay too long in digitized areas like the corridor they're currently in. In such areas, humans are converted into data after a few hours, and imported to SE.RA.PH. Even Servants will only last a few days. Meltlilith warns Ritsuka everyone will be converted into data well before SE.RA.PH reaches to the bottom of the trench. When Ritsuka says BB told them SE.RA.PH reach the trench's bottom in a few hours, Meltlilith explains time in SE.RA.PH passes a hundred times quicker than in reality. She also explains that while SE.RA.PH is based on Seraphix, it is significantly larger. She then decides they need to find a safe area to serve as a base before Ritsuka gets digitized.

After fighting a bit through SE.RA.PH, Meltlilith learns more of the situation from Ritsuka. Ritsuka asks her why she chose to protect them, but she asserts it was because she though they were important when BB payed extra attention to them. Moving on, Meltlilith explains that SE.RA.PH is a digital labyrinth loosely based off of Seraphix. However, the current SE.RA.PH is only an imitation of the original, which is significantly larger. She explains the original SE.RA.PH was a city-type engine designed to run the Moon Cell Automaton, a construct made of photonic crystals inside the moon. She continues SE.RA.PH is also a world where many humans, NPCs, and AIs live in. It was the site of the Moon Holy Grail War, the Moon Cell itself being the prized Holy Grail. Meltlilith explains the Moon Cell chooses which human will use, but as it is an observational device, it cannot know the quality of the human. As such, it created the Holy Grail War as a fair and impartial albeit violent way to weed out the candidates. It invited 128 Masters to SE.RA.PH to compete in the Holy Grail War, choosing the surviving Master. As a result, the Moon Holy Grail War turned into a slaughterfest, similar to Ritsuka's current situation. However, the difference is that the Moon Holy Grail War was a tournament, unlike the free-for-all Ritsuka is experience. The Moon Holy Grail War was divided into seven rounds, and the administrators deciding who fought who, which Meltlilith believes it was more rational than the current one. Ritsuka ask her why she looks like BB, so she explains BB is a high-grade AI who was stationed on the Moon during the Grail War. BB was designed to keep Masters healthy during the war, but she bugged out and started to style herself a ruler of the moon. Her prime directive of protecting humans eventually turned managing humans as a result of several errors. BB even tried to usurp control of the Moon Cell, but she lost to a human. Meltlilith then reveals she is an aspect of BB's personality she removed from herself; Meltlilith is the Alter Ego created from BB's sense of pleasure. As she and the other Alter Egos were created from BB, they all look like her. She then warns Ritsuka of a Servant up ahead. The Servant is revealed to be Gawain, who find it hard to believe Meltlilith is a Heroic Spirit. She confirms she isn't a Heroic Spirit, but she realizes Gawain wasn't among the 128 Servants. Gawain then notices Ritsuka, glad he has finally found them after being separated during the Rayshift. Ritsuka is confused, but Gawain asserts he was one of three Servants who rayshifted with them. Ritsuka recalls how Nero, EMIYA, and Tammao rayshifted with them, but Gawain continues to assert his claim. Gawain then decides to join Ritsuka in order to resolve the situation and return them safely to Chaldea. After Ritsuka explains the situation, Gawain thanks Meltlilith for saving Ritsuka, but he remains suspicious of her. Meltlilith decides they need to find Ritsuka's other Servants in addition to finding a safe area. BB then suddenly appears before the group, deciding to punish Ritsuka for breaking the rule of having more than one Servant. Gawain whispers to Ritsuka that he'll try to capture BB, but she asserts nothing happens in SE.RA.PH unless she wants. She then summons Robin Hood, who she orders to kill the group. The group kill Robin, but Gawain is confused by the slot machine that appeared at the battle's start. BB explains she created it to interfere with the battles regardless of the strength of Masters and Servants. She tells Ritsuka that she'll let them go free if they either win her Grail War, or if they discover the secret behind SE.RA.PH. She states she will continue to watch their progress. Meltlilith asks her why she personally appeared, to which BB answers she did so to personally cause mischief. BB asks Meltlilith why she joined the humans, to which Meltlilith claims she is following her own rules. She also explains to BBB that she shouldn't care how she spends her time, as long as she fulfills her ultimate as role as a Sentinel. She then tells BB to go away, so she and the others can explore in peace. BB reveals she locked several SE.RA.PH's passageways, which she'll discreetly open for a fee. She also warns the group not to explore too far, otherwise they'll encounter stronger Attack Programs and Sentinels, special Servants tasked with guarding SE.RA.PH. She then explains that SE.RA.PH is like the digital embodiment of humanity's inner world, which used to be also called the Sakura Labyrinth. She continues the Sakura Labyrinth and the Sentinel convert huamn emotion into defensive mechanisms. Each Sentinel is created a powerful passive skill called Karmaphage, which makes them nigh unbeatable to a normal Servant. While warning the group to keep away from the Sentinels, BB also says they need to defeat the five Sentinels, who each guard one fifth of SE.RA.PH, if they wish to fully investigate SE.RA.PH. She then resurrects Robin, but she sends him away when he begins to complain. Before leaving, she corrects Da Vinci's assertion that Rayshift to the future is impossible. She states it isn't inherently impossible, however it is for Chaldea as they cannot rayshift past the year 2019.

Later, the group defeat Gilles de Rais. Ritsuka and Gawain were confused by his behavior, but Meltlilith explains most Servants in SE.RA.PH have already succumbed to their desires. Gawain then questions why they haven't encounter any Masters yet. Meltlilith reveals the Masters all died a long time ago as soon as they summoned their Servants. Gawain questions the Servants are still fight even though they don't have a reason to, but Meltlilith reminds him only the Servants from Chaldea are acting rationally. She starts to ponder if BB is responsible when she notices something. Ritsuka thinks it's a Holy Grail, and touches it despite Gawain's warning.

Upon touching it, Ritsuka see the final memories of a Seraphix crew members. On January 2019, every ship set ablaze, the helicopter was destroyed, and Seraphix lost all communication with the outside world. As well, parts of the base were digitized. By Feburary, the crew was down to about a hundred survivors, and they moved to the Central Command Room where the digitization occurs the least. They decides to wait till May for Chaldea to notice Seraphix's situation. However, Chaldea never came, and Seraphix's crew soon became violent. In March, they executed the director, Hideyasu Ajima, for not anticipating the situation. Next, the assistant director was executed for failing to resolve the situation, then a woman who lost the key to the cleaning room, Then, the doctors, who became useless when the medicine ran out, and the people who went against Beckman were sacrifice to the monsters outside. Other people were executed for mild transgressions or utter xenophobia. Despite all of this, the remaining crew remained optimistic the situation would be resolved in a few days. However in April, they learned the time difference between digital and reality, meaning any help from Chaldea could take more than fifty years. The memory ends with the crew members being killed by a sledgehammer by Beckman loyalists for breaking the rules.

The group eventually come to a fork; one path leads to the Chest, formerly the Central Command Room, while the other leads to the Thighs, formerly the dock and heliport. Gawain understands each area is named after a part of the body. He correctly assumes the current area is the Hair, and asks what the area originally housed. Meltlilith answers it housed the submarine cables, pump, and power plant. She says it's relatively safe, but the important area is the Chest, where the group may find survivors. Tristan then suddenly appears, disappointed at Gawain for associating with Meltlilith. He's surprised to see Ritsuka, as they're the only Master he's encountered, and mentions he's already killed seven Servants. However, he's also disappointed by Ritsuka for associating with Meltlilith. He tells Ritsuka and Gawain to move of his way so he can kill Meltlilith. Gawain asks Ritsuka whether they should move or stay after warning that Tristan's arrows pierce all he sees without mercy. They decide to stay, so the group are forced to fight Tristan. During the battle, Tristan tries to kill Meltlilith with his arrows, but her liquid body negates the attempt. She then pins him down, and decides to spare him. She tells Gawain to finish him, but he refuses to do so as it is her victory. He realizes she wants to let Tristan go, but she refutes him. Ritsuka and Gawain decide Tristan will join them despite Meltlilith's protests. Tristan accepts despite Meltlilith being part of the group. After hearing SE.RA.PH was originally Seraphix, Tristan reveals he was only summoned ten days. Gawain asks him if he participated in the Grail War, to which Tristan answers he explored SE.RA.PH to find and capture BB while killing any insane Servants he encountered. He then recalls an Alter Ego he's encountered multiple times, each time forced to retreat to avoiding being crushed. He calls the path leading to the Chest Breast Valley, the domain of the Alter Ego. Meltilith reveals the Alter Ego is Passionlip, who was born from BB's love and hate.

The group come to the path leading to the Chest when Ritsuka begins to feel the effects of digitization. A woman then appears, mistaking Ritsuka's Servants as the same the insane ones she encountered so far. She calms down though when she notices Ritsuka's uniform is that of Chaldea. She introduces herself as Marble Macintosh, robotics operator on Seraphix. Gawain introduces himself and Ritsuka, and asks her what she knows. Marble doesn't answer though when she notices Meltlilith. She asks the group why they have an Alter Ego, believing humans and egos are supposed to be mortal enemies. She tells Gawain to kill Meltlilith when she notices what she was running from has caught up to her. She tells the group to run, as her pursuer crushed all new 128 Servants when they arrived here earlier. The pursuer is revealed to be Passionlip, who Meltlilith reveals to be one of the Sentinels. The group fight her, but they're forced to retreat when she uses Trash & Crash on the passageway. with the passageway now compressed into a cube, the group return to the fork with Marble.

Gawain asks Marble what she saw in the Central Command Room. She answers the Command Room, and the only survivors besides her are Arnold, Ms. Trapayne, and Holly. However, the only people left in the Command Room are her and Arnold. She ran away though when they began to fight over food. Meltlilith thinks they should abandon Marble, but Ritsuka decides they should find a safe area. Asked by Gawain if she knows a safe area, Meltlilith answers there is a building in the Thighs with magical protection, and too many indecipherable elements to be digitized. It is a christian chapel built to provide Serahpix's crew with spiritual support. Tristan reveals Vlad III guards that area, so he must be defeated if the group wish to get to the chapel. As the group travel towards the chapel, they notice many Servants and humans impaled on Vlad's stakes. Vlad prepares to fight them, and reveals a Demon God inhabits his body. As Vlad disappears with his defeat, Ritsuka asks him about what he said earlier, but he doesn't answer. Instead he tells them that EMIYA is in the chapel, but says he cannot be trusted.

The group enter the chapel where they meet, not the regular EMIYA, but EMIYA Alter. In answer to Meltlilith's disappointment, he reveals BB switched him out with his other self. After Ritsuka explains what happened so far, EMIYA Alter replies he's been watching from the chapel roof. He then reveals there is a terminal hidden behind the altar that contains a report. However it is locked to even Servants and Alter Ego, so its key needs to be found. The group believe the report may contain a clue, and decide to search for the key tomorrow. Meltlilith decides to rest outside when Ritsuka notices a broken ceramic figure. In her thoughts, she thanks Ritsuka for noticing "her", even if it's only the remains.

After purchasing the terminal key from BB for a large amount of Sakurament, Ritsuka uses it on the terminal. An audio guide in the terminal warns the records can only viewed by one person at a time, and that they'll be deleted after playback has concluded. Marble explains the terminal sends the data directly into the brain of whoever is viewing the records. The terminal then plays the records from February 7, 2019. The record keeper introduces themselves as a therapist, who was invited to join Seraphix back in 2016. They go on to recall everyday life in Seraphix while they dealt with their patients at the church. After listening to so many complaints, the therapist began to question why Seraphix was built. Then on January 2019, Seraphix lost all contact with the outside world, and strange happenings began to occur. The therapist joined the medical team to help the victims when they noticed a monster with many eyes that preys on human minds. On Feburary 2019, they began to change like the rest of the crew, losing all sense of morality. However, their obligation to their job helped them keep their rationality. On March 2019, they are severely injured and thrown into the church, which they quickly lock. They decide to leave a record behind, terrified something more terrifying than the hysterical crew is eating away at their mind. They then begs somebody to not the planetarium, to not let its experiments continues, and to kill them. After the record ends, Gawain believes the crew summoned BB of their own accord. Meltlilith reveals the planetarium is in the middle of SE.RA.PH, and that it's the source of the digitization. Ritsuka, Meltlilith and Gawain decide to continue explorable while Tristan and Marble stay behind in the chapel. EMIYA Alter leaves to kill the Servants to keep the others' exploration unimpeded as Gawain believes.

The group discover the upper part of Arm, and Gawain asks Meltlilith if she knows what was originally here. She guesses it originally held robotic operations, which was used for seabed investigations. She continues if they were continue to the Thenar, they should find the Arm used to examine the soil. Ritsuka asks if the Foot area is the same, but Meltlilith answers the legs had more destructive purposes. BB then suddenly contacts the group, and reveals SE.RA.PH is the only thing keeping the humans alive. She also tells them of her updated stock of Gate Keys and various other items. She then introduces the next Sentinel, Tamamo Cat whose been subjugated by BB. After Cat is defeated, BB is so annyoned at her not using her Karmaphage, she sends her through a trapdoor while ordering to remain at her designated position. BB tries to end contact, but Meltlilith stops her to ask about the 128 new Servants Marble mentioned earlier. BB answers she summoned them herself, and she'll continue to do so until a proper recreation of the Battle of the Time Temple is made. Gawain asks her how she knows of that battle, but she answers the group's action lead to draw the connections between the events. She then tells the group that there's only one real world hour left before SE.RA.PH hits the seabed before ending contact.

The group eventually make it to the Flank Separator, which used to house separator devices for desalination, and where collected resources passed through before packages. A human memory then appears, and Ritsuka promptly touches it. It is the memory of a man who was brought to Seraphix to serve as a fixer, someone who kill those who would disrupt operations or leak secrets. He recalls how the survivors divided into factions, and how was chosen to enforce Beckman's laws when he took control. While reveling in dominating others, he began to regret when he learned about love from a certain woman. He declares his complete and utter devotion to her, ready to do absolutely anything for her. He claims he doesn't fear anything except the fear that the woman will despise him, and discard him. The memory ends with the man declaring he would rather watch the world burn than lose the love he found.

The group, joined EMIYA Alter are nearing the area's final zone, which is assigned to a Sentinel as Meltlilith explains. Gawain asks her what Sentinels are, as he was under the impressions they were all Alter Egos. Meltlilith admits Alter Egos were originally salvaged to be made into Sentinels. However a Sentiel doesn't need to be a Alter Ego, as BB can anyone she wishes into one. She only needs a Spirit Origin that can handle a Karmaphage. Meltlilith explains how she and the other Alter Egos were originally made to adhere to the emotions they were born from, however they eventually learned to control their behavior. She then recalls a human who once told her that she was truly alive. The group eventually encounter Cat, and fight her. After she is defeated, EMIYA Alter seemingly fatally shoots her. However she gets up alive while revealing she was planning to rejoin Ritsuka's side, only joining BB to survive. EMIYA Alter reveals he used his knowledge of Magic Circuits to target and destroy the parts on Cat's Spirit Origin infected by the Karmaphage. Now free of BB's control, Cat joins the group.

Returning to the chapel, the group discuss whether to continue exploring, or find a way to escape. Gawain asks Marble if they were any other facilities in Seraphix besides the ones he and others visited. She answers there is the soil survey room, the resource compression and drying area, and the dump. Gawain has Meltlilith reveal her knowledge of the other facilities. Understanding they won't discover anymore on the front side, Meltlilith decides to tell the group of the other side. She explains SE.RA.PH has a two layer structure, with a front side and back side. She reveals she was originally a back side Sentinel, but BB scrapped her after she disobeyed. EMIYA Alter asks her how they get to the back side. Meltlilith answers humans and Servants cannot cross the border between the sides, and only Sentinels can cross it. Thus, she says the only way to get to the back side would to flip SE.RA.PH over, but she doesn't know how. Ritsuka however realizes a way to do so after listening to Cat's nonsensical rambling. Gawain asks if getting to the back side will get them to the Central Command Room, to which Meltlilith answers it will. She continues that once the group arrive on the back side they only to reach the Command Room's coordinates, and flip SE.RA.PH again to arrive at the Chest. While this method will help them bypass the passageway Passionlip destroyed, they will still need to fight her. Meltlilith reveals the restraint on Passionlip control her, so if they're destroyed then she likely help the group.

Leaving Tristan and Marble at the chapel, the group, joined by Cat and EMIYA Alter, soon arrive at the Flank Separator. Following Cat's advice, Ritsuka hits the Separator, and SE.RA.PH starts shaking. BB contacts the group, and sends a Sentinel, Elizabeth Bathory, to punish them for their transgression. After the group defeat Elizabeth, BB decides she'll let them go to the back side when she notices Passionlip approaching despite not being ordered to. Meltlilith urges Ritsuka to hurry up with flipping SE.RA.PH over before they're all compressed by Passionlip. Gawain holds her back, as Ritsuka finally succeeds in flipping SE.RA.PH over.

With the exception of Gawain, the group arrive on the back side. However, they're greeted by Suzuka, who soon fights them after being insulted by Cat despite orders by BB to escort them. After the fight, Cat asks Suzuka why she became Sentinel, confessing she became one out of necessity to survive. Suzuka boasts BB recruited because of her winning streak, and confesses she only care about winning the Grail War. She then gets a phone call from BB, who orders her back to the temple, and not to fight the group. She questions the order, but she stops when told Chaldea Servants don't count. She then hangs up, assuming BB has a plan. She tells the group to check out the Nape if they plan to head to the Command Roon. She then leaves saying the Seraphix's crew brought the crisis on themselves, and Seraphix was never just oil rig. EMIYA Alter says he investigate the front side beforehand, and found it nearly all the fatalities needed for a oil rig. Thus, he questions why Suzuka said what she did, and wonders where they can find evidence. Cat then remembers they still need to go back to the front side and save Gawain. EMIYA Alter however opts instead for heading towards the Chest, and flipping SE.RA.PH to get to the Command Room while avoiding Passionlip. He notices the area corresponds to the Front Gate on the front side, and asks Meltlilith what it was used for. She answers that it was a gate reserved for special employees who were mages. EMIYA Alter guesses the gate used solely by employees who reported directly to Chaldea. He quickly remembers though that everyone at Seraphix worked for Chaldea. He then realizes that the only people who would use the gate would those who work directly under Chaldea's owners, the Animusphere family. Cat then tells the group she heard an alarm telling them to present a pass now, and fail to do so in five second will result in their immediate termination. EMIYA Alter quickly realizes it meant termination literally, as he sees enemies approaching. After defeating them, the group prepare to continue exploring when Robin arrives. He gives them a message from BB saying Passionlip is waiting for them on the front side, and they should submit to her since they can't possibly beat Passionlip. He also tells them BB developed a secret weapon that can break "the shackles" on Passionlip's heart, and it can used also to remove her restraints. EMIYA Alter questions the point of defeating Passionlip, but Ritsuka decides they'll free her. Robin then takes everyone except EMIYA Alter back to the front side. BB then appears to offer EMIYA Alter a chance of survival if he kills every surviving human on SE.RA.PH, and captures Ritsuka. If he does that he'll learn the secret about SE.RA.PH, as part of his job as Counter Guardian. EMIYA Alter promptly agrees to join BB.

The group arrive back at the front side being encroached by Attack Programs and Passionlip. After they defeat the programs first on BB's order, BB reveals the only way to defeat Passionlip is to use the Maiden Coaster, a battle to conquer the mind. Meltlilith realizes that it's connected to the Code Cast Ritsuka earlier. She then asks BB if it's possible, as she thought only humans could analyze human minds. BB answers she can manage if the target is a Karmaphage infected Servant. She continues that Ritsuka will need place their hand on Passionlip's chest, but the group will need to pin her down first. Robin and Meltlilith argue about their inability to overpower Passionlip when a severely injured Gawain suddenly arrives. He confesses he also wishes to save Passionlip, and then holds her long enough for Ritsuka to touch her chest. Upon doing so they are converted into Psuedo-Spiritrons by BB in order to enter Passionlip's mindscape. After being defeated in her mindscape, Passionlip collapses followed by Gawain. However he quickly gets back up, and decides they should let Passionlip rest at the chapel. After Cat returns to the chapel carrying Passionlip, Robin sneaks off somewhere. Ritsuka, Meltlilith, and Gawain then continue onto the Command Room. However, to their shock, they find a Demon God inside. After they kill it, a man emerges from hiding, and correctly surmises Ritsuka as a member of Chaldea. He introduces himself as Arnold, secretary to the director of Seraphix. He asks how the rescue is proceeding, and if the digitization has stopped. He becomes disappointed in Ritsuka though when he learns they're only one from Chaldea, and how long it took them to get into the Command Room. Meltlilith asks him what happened to the rest of the staff, but he's shocked that an Alter Ego is with the group. Ritsuka and Gawain convince him that Meltlilith is an enemy of BB, and he answers he's the only survivor. He recalls a woman who ran away, but he doubts her survival. He also mentions a corpse of another staff member is in the nearby locker, having died of a drug overdose. Ritsuka tells him that Marble, the woman who ran away, is alive to his surprise. Gawain says they should look over the records kept in the room, and then search for the Planetarium. Arnold tells the group that outsiders aren't allowed to view the records without authorization, and insists the planetarium doesn't exist. He continues they need authorization from the director of Chaldea, the head of the Animusphere family, to access the records. Meltlilith however reveals the data was deleted long before they arrived, leaving them on their alone to find the planetarium. She then notices that a passcode for the chapel terminal that wasn't there before. Gawain wonders what it's doing in the Command Room, to which Arnold replies that a woman commuted from the chapel to provide therapy to the religious staff members. However, they eventually came to believe God abandon them, and killed the therapist slowy. She left the passcode behind before she died. Ritsuka then asks about the Demon God, which Arnold says suddenly emerge from the floor one, and killed and consumed the people who murdered the doctors. Beyond that though, the Demon God left the others alone if they kept their distance. Ritsuka and Gawain point out how it felt different from the Demon Gods they're familiar with, as if it was empty. The group then decide to return to the chapel, taking Arnold with them, who properly introduces himself as Arnold Beckman.

Back at the chapel, Passionlip introduces herself to everyone, and decides she'll help to thank Ritsuka and Gawain. Tristan allows her to join as he sees she and Meltlilith are not under BB's control. He's concerned though EMIYA Alter will kill them, but EMIYA Alter insist he is only here to exchange information. Marble wonders to herself if Arnold was wrong to command the others to attack the Alter Egos if it was possible to talk with them. Arnold doesn't object since Ritsuka is the leader, then goes up to the second floor with Marble to rest. Ritsuka then uses the passcode found in the Command Room to access another record on the terminal. The record starts with its keeper confessing they are recording it in their sleep through an unknown method. They then introduce themselves as the Demon God Zepar, but correct themselves that they've been possessed. They then reveal Seraphix was created to run a certain experiment. While it functioned as a oil rig, it also contained a secret mage's workshop deep inside. This was done to avoid the watchful eyes of the Lords, and because the experiment could only be conducted on the seabed. The record keeper then reveals the resources brought into Seraphix, also contained human subjects of varying Magic Circuits and Rayshift compatibility. They then say it's possible to revert Seraphix back from its partially digitized state. They reveal themselves to be the therapist from the previous record, and they were contacted by Zepar several days after locking themselves in the chapel. Zepar commends humans for defeating him, and expresses particular interest in the amount of energy the human mind can potentially generate. He wishes to help humans realize that potential, but his body was destroyed with his defeat. Zepar prepares to possess the therapist while also apologizing for it. The therapist tries to convince Zepar to possess someone else, but Zepar rejects it as human bodies aren't significantly different. Zepar assures the therapist that he won't erase her mind just yet. He continues that someone will come to destroy him once it's been determined a Demon God still lives. Zepar then says they need to rest to regain their strength to gain the time to build their world. For that reason he'll pose as the therapist to learn everything they can about Seraphix. Zepar continues that in time he will convert Seraphix into another world, and be reborn as a Demon God, which is when he'll free the therapist. Afterwards, he'll reward the therapist for her suffering by sparing only her. Zepar then possesses the therapist, and uses them to transform Seraphix. The therapist reveals the next step of Zepar's plan after Seraphix is completely digitized is "connection". She further reveals Seraphix was rayshifted to 2030 to avoid Chaldea from discovering Zepar's plan. From there, it will sink down into the Mariana Trench, and once it reaches the bottom, Zepar will be reborn. The therapist then reveals she was disposed by Zepar after BB was summoned to be his new partner. She says she did everything to save Seraphix while feeling her consciousness fade away. She ends the record urging for someone to not let SE.RA.PH reach the seabed to prevent Zepar from being reborn. While the others are shocked a Demon God is behind the digitization, Meltlilith confesses she knew Zepar summoned BB to serve as his navigator by running SE.RA.PH. She also reveals BB placed a number of restrictions on her and Passionlip to specifically prohibited them from revealing SE.RA.PH's true origin and purpose. She is surprised though BB allowed a record revealing Zepar's plan to exist. Gawain is surprised to discover one of the four Demon Gods to escape Time Temple is hiding in Seraphix. EMIYA Alter surmises Zepar somehow learned of the Moon Holy Grail War from an different timeline, and summoned BB to transform Seraphix into SE.RA.PH so he can be reborn. Tristan then questions why BB summoned Servants, but Passionlip is unable to discern BB's way of thinking. Meltlilith reveals the Servants were summoned in order to procure the Psuedo-Spiritrons needed to keep SE.RA.PH running. The group unanimously decide to defeat the Sentinels and BB before stopping Zepar's plan. Outside the chapel while others are resting, Meltlilith shares her data with Passionlip so she can fully understand the situation. She asks her to led her Virgin Laser - Palladion, and says the three of them will defeat that monster this time. Later in the chapel, Gawain is ambushed and consumed by something.

The next morning, everyone discovers that Gawain was killed while they were sleeping. Meltlilith and Passionlip are accused by Tristan, EMIYA Alter, Arnold, and Marble because they're Alter Egos. Meltlilith points she and Passionlip wer outside at the time, and Gawain was too wary of her to allow to ambush her. Seeing the lack of evidence, Tristan asks Ritsuka to continue exploring SE.RA.PH while continues to stay behind to protect Marble and Arnold. He also asks EMIYA Alter to accompany Ritsuka so they can keep an eye on him. Tristan confesses he is suspicious of both the Alter Egos and EMIYA Alter, but he understands the Alter Egos wish to protect Ritsuka while EMIYA Alter isn't especially concerned. Thus, he will have the Alter Egos protect Ritsuka while EMIYA Alter keeps an eye on the Alter Egos.

Returning to the back side, the group defeat Julius Caesar. EMIYA Alter asks Meltlilith if Suzuka is the only Sentinel left on the back side. She answers she isn't sure what area Suzuka is using as her temple, but she guesses it's at the center of SE.RA.PH, the Spine. She also reveals Suzuka has been given the strongest Karmaphage, and she was put in charge of the back side. Before heading to the Spine, EMIYA Alter suggests to Ritsuka to activate the Maiden Coaster on Suzuka to negate the effects of her Karmaphage. The group later arrive at the gate leading to the Spine, forcing them to purchase another gate key from BB. Arnold then contacts them using equipment he had Tristan bring from the Command Room. He orders them to flip SE.RA.PH. once they're at the spine, saying they should arrive at the planetarium. He also reveals SE.RA.PH will the reach the bottom of the trench in 15 real world minutes, or 24 hours in SE.RA.PH time. He ends his transmission after saying he'll meet them at the planetarium.

Entering the Spine, the group discuss Suzuka's motives while traveling to her temple. They soon arrive at the temple where Suzuka greets them ready to fight. She reveals she and Tristan are the only Servants left in the Grail War, so she'll kill him after killing the group. She proves too fast and strong for them to pin her long enough for Ritsuka to open her Maiden Coaster. Arnold suddenly contacts the group to tell SE.RA.PH has started to sink faster, so he orders them to defeat Suzuka quicker. Ritsuka ask Suzuka if she's fine with being Zepar and BB's flunky, which angers her. She insists she only belongs to the Master who summoned her, and confesses she wants to win the Grail War to grant their final wish of not wanting to die for nothing. In respond to her conviction, Cat uses her ultimate technique to trap Suzuka. Ritsuka uses this opportunity to open Suzuka's Maiden Coaster with the key they bought from BB earlier. After she's defeated in her mindscape, Suzuka tries to jump off a cliff as she begins to disappear for some reason. Cat stops her though, and convince her to join them. Meltlilith says they should flip SE.RA.PH now when a Demon God emerges from the ground. Suzuka reveals the dump is beneath them, but they should destroy the Demon God first. After the Demon God is destroyed, Arnold contacts the group to tell them that there are only eight hours left before SE.RA.PH reaches the seabed. He orders them to return to the chapel, but Ritsuka decides they'll rescue Meltlilith from the dump that she was knocked into earlier. Arnold repeats his order, but Ritsuka still refuses to give up on Meltlilith despite EMIYA Alter and Tristan saying it's impossible to save her now. Suzuka however has EMIYA Alter lend her a tow cable so she and Ritsuka can be lowered into the dump. EMIYA Alter warns though the cable can only extended with magical energy to about five kilometers. Ritsuka and Suzuka then get ready to lower themselves down into the dump.

Meltlilith awakens to find herself into the dump. She tries to get up, but her legs were broken by the fall. She recalls the time she spent with a different Ritsuka, and prepares to submit to her fate when Ritsuka and Suzuka arrive to save her. Suzka protects Meltlilith and Ritsuka from the monsters, but they seem to be innumerable. The trio try to retreat, but they find the cable has been cut. Tristan arrives to save them, but now he's also trapped with them. Meltlilith warns the others they can't let Arnold into the planetarium, as he'll self-destruct from the desires it will unlock in him. She then realizes she is in the Calf, and BB arrives to confirm the Cruel Thenar, Meltlilith's former workplace, is ahead. BB prepares to send the group further down into SE.RA.PH, warning it'll reach the seabed in five five and a half hours.

Meanwhile at the chapel, Arnold confesses he was responsible for the deaths of most Seraphix's staff. He ponders on how to force Ritsuka into following his orders when EMIYA Alter arrives. He tries to order him to retrieve poison from the sickbay, but EMIYA Alter kills him before he can finish. He then kills Marble, revealing he needed all Seraphix's staff dead to prevent Animusphere's experiment from being repeated. He prepares to go and destroy the planetarium when a mysterious voice criticizes his ruthless and callous approach. He recognizes the Spirit Origin pattern, and the voice in turn recognizes him. They reminds him of the cult he slaughtered, even though the only evil person there was the woman who founded it. They reveal themselves to be that same woman he killed after massacring the other members who tried to protect her. She also reveal she was the once that consumed Gawain, and prepares to EMIYA Alter next.

The group are sent by BB to the Cruel Thenar, Meltlilith's former designated area. Meltlilith explains that on Seraphix, it was officially used for oil excavation, but secretly it was used to investigate Leylines. She summarizes it as investigating the Earth's brain waves, but she doesn't fully explain it since time is short. She then asks Ritsuka to open her Maiden Coaster, knowing they brought the key to her heart from BB earlier. Passionlip says if Meltlilith is defeated in her mindscape, her Karmaphage will will also disappear, and the area will be unlocked. Ritsuka opens Meltlilith's Maiden Coaster, and eventually defeats her in her mindscape. Even though she said there wasn't much time left, Meltlilith sits down for some reason. Tristan questions her since they find the planetarium. She then transports everyone to front side in front of the chapel. The group enter the chapel to rest there, but they see no signs of Arnold, Marble, or EMIYA Alter. BB then makes an announcement that SE.RA.PH will soon reach the seabed, and offers the chance to fight her at the planetarium. Ritsuka, Tristan, Cat, Passionlip and Suzuka leave for the planetarium while Meltlilith stays behind.

The group arrive in BB's studio in the planetarium, and fight her. After BB seemingly disappears, the room becomes pitch black, and sound is also muffled. Someone tries to ambush the group, but they fail in their attempt. The group then find BB's studio gone, and discover 128 Coffins with people still inside. Suzuka realizes they're the Masters who summoned the 128 Masters, and demands EMIYA Alter to explain things. He reveals Seraphix's core is called the Celestial Body Simulator, System Animusphere. He continues that it is here Zepar used the Master candidates to summon the 128 Servants. He also reveals the Masters in the Coffins died long ago, but long as the Coffins are actives, they still be used endlessly as biological circuits. He continues the corpses summoned 128 Servants continuously until Ritsuka arrived. He confesses he destroyed the Coffins' power source, and prepares to kill Ritsuka to remove all knowledge of the planetarium's existence. Robin then suddenly arrives, and helps the group defeat EMIYA Alter. After he's defeated, Marble suddenly appears, and Cat demands she reveal herself. Marble changes into true self, reveal Marble was merely an artifice. She reveals she was the therapist who worked at the chapel, introducing herself as Kiara Sessyoin. She reveals after many conversations with Zepar, they reconciled and decided to try to save people. She then reveals herself to be Beast III, the Beast of pleasure. She explains SE.RA.PH is shaped like a human body is because Zepar transformed Seraphix into her body. Robin asks her if she was the one summoned BB while under Zepar's influence. Kiara confirms such, and reveals Zepar taught her about parallel worlds. She eventually learned of another version of herself, who acquired the Moon Cell in the Far Side of the Moon. Impressed by this version of Kiara, Zepar linked the two Kiaras together. Passionlip realizes Zepar used Kiara as a catalyst to give SE.RA.PH form. She reveals Kiara swallowed BB, Meltlilith, and her back in the Moon world. Since Kiara served as the basis of SE.RA.PH, Meltlilith and Passionlip were salvaged from her to become Sentinels. Kiara explains Zepar lacked the means to run SE.RA.PH, so she had rely on the Alter Egos and BB, who had hacked SE.RA.PH from the Far Side of the Moon. Suzuka demands to know where Zepar is now, and how many Servants and Masters she consumed since she and SE.RA.PH are one. Kiara answers she lost count at seventy or so, which makes the group see her as the monster she truly is. Suzuka and Cat attack her with their Noble Phantasm when SE.RA.PH cracks the seabed. Passionlip explains it will continue to sink until it reaches the Earth's core, and once it arrives, Kiara will become one with the planet. Kiara proclaims that doing so she can bring salvation to the people. Before that however, she easily kills everyone except Ritsuka when they try to fight her. She tries to consume Ritsuka, but they're saved when BB rayshifts them.

In a flashback, it revealed Zepar used Kiara to effectively gain control of Seraphix while learning much of human pleasure during that time. Even though such a thing is useless to a Demon God, he found himself asking Kiara to help him understand. He recalls Kiara inciting chaos among the Seraphix staff after he transformed Seraphix into SE.RA.PH. Even though he only wanted a place to hide, it instead became like hell to his horror. Zepar recalls further how Kiara seduced the personnel to open the planetarium, and BB and the 128 Servants were summoned. Kiara took control and ruled SE.RA.PH from the behind the scenes all the while claiming she was doing it for Zepar. It was at this point Zepar realized that Kiara has overtaken him. He recalls telling her of the four Demon God survivors' plans to create Singularities to achieve their own separate goal. She refused to create a Singularity, instead opting to become one. That is when Zepar realized the uncontrollable nature of human desire, and tried to unsuccessfully to separate himself from Kiara. He recalls how Kiara only permitted him to reside in her pinky finger while pleading with her to let him free. Eventually though, Kiara releases him from her pinky, and he quickly fades away afterwards. Kiara then ordered BB to start the Grail War to keep her entertainment while SE.RA.PH falls.

Ritsuka find themselves in an old classroom along with everyone else. BB reveals she reversed time to undo the deaths of Suzuka, Tristan, Robin, and Cat. She explains a time leap of approximately three hours is possible in the digital world if it's within a Quantum Time-Lock. The right coordinates also needed, which is the purpose of the class that's located approximately hundred meters above SE.RA.PH. BB explains further that SE.RA.PH digitized the Mariana Trench as it passed through it. Thus, under these circumstances, the higher they go, the further they go back in time. Tristan wonders if it's possible to return to time before Ritsuka's arrival if they were return to the surface. BB replies that it is theoretically possible if they had the right coordinates. The problem though is escaping Kiara's sexual allure, which is acting like a gravitational field. BB explains the group would need exceed to the speed of light to escape, and while possible in the digital world, they would be destroyed in the process. She then reveals she was summoned to stop Kiara's plan, and that Kiara forced her to manage SE.RA.PH until now with the Grail War's conclusion. After Robin asks Beast III is, BB reveals Kiara is only one of half of Beast III, "R". She continues that she learned some Beasts come in pairs like ying and yang, and reveals Kiara is becoming the R of Beast III. She reveals further that Kiara used SE.RA.PH to become a Beast, but she's also still bound to it. The group then prepare to fight Kiara to prevent her from fusing with the planet.

The group arrive back at the planetarium to destroy Kiara. But before that though, Meltlilith asks her why she decided to become a Beast. Kiara answers it was because she was jealous of delight she felt from Zepar's memories of the Battle at Time Temple. After revealing she wishes to worshipped as a god of pleasure, she tries to convert the group into her followers. It is negated however by BB's secret weapon which counteracts the erotic magical energy in SE.RA.PH for the next five minutes. Kiara then decides to destroy the group more directly. The group are able to defeat her, but the area fades away. SE.RA.PH's gravitational field weakens, so everyone begins to float. Passionlip states SE.RA.PH is accelerating, and that she also senses Demon Gods. Kiara boasts of her victory, but Meltlilith reveals she knew she would banish them from SE.RA.PH. She points out that disabling SE.RA.PH's gravitational field has left it defenseless. At Meltlilith's request, Ritsuka uses their remaining Command Spells on her and Passionlip to give them a boost of magical energy. Meltlilith then has BB transport everyone expect her and Passionlip to safety.

Meanwhile at BB's studio, she warns SE.RA.PH's descent is accelerating, and an innumerable number of Demon Gods are trying overflow out from it. She explains that as SE.RA.PH rapidly expands, it will unleash a rain of Demon Gods upon the sea. She's doing her best to halt SE.RA.PH's expansion, but she lacks the processing power to do it alone. She says they needs someone with Moon Cell processing power, which is when Suzuka offers to help.

It is revealed in a flashback that Meltlilith and Passionlip previously failed to destroy Kiara. After injuring Meltlilith's arms, Kiara killed a different version of Ritsuka as punishment for defying her. She also stopped BB's time leap due to part of her still existing inside of Meltlilith and Passionlip, their Karmaphages. Meltlilith vows to redo everything, and help Ritsuka instead to free the Sentinels of Kiara's influence. Passionlip uses Virgin Laser - Palladion to launch her upwards at speeds exceeding the speed of light so she travel back in time. Meltlitlith visits a past version of herself in the chapel, and shares her memories with her. In order to prevent Kiara from realizing the truth, the past Meltlilith committed suicide, leaving only a broken ceramic figure.

Passionlip uses Virgin Laser - Palladion to launch Meltlilith at Kiara. Meltlilith crashes into Kiara, crushing her heart. As her body begins to crumble away, Kiara turns her hair into Demon Gods to grab Meltlilith in an effort to possess her. Her effort is made in vain though as a EMIYA Alter destroys the Demon Gods entangling Meltlilith. He then puts a cable around Meltlilith's waist and has her pulled up to safety. Soon afterwards, Kiara's body crumbles away completely.

Ritsuka wakes up in BB's studio, and they ask what happened to Meltlilith and Tristan. It is then revealed Tristan was the one who pulled Meltlilith up. EMIYA Alter also disappeared, having used the last of his strength to save her. However because her Spirit Origin was too damaged with the second use of Virgin Laser - Palladion, Meltlilith begins to disappear. BB warns her that because she and Passionlip were born from Kiara, they will disappear forever since Moon Cell will not record them. She reveals though she knows a way to register irregulars into actual Servants. She continues she intended to use that method to stay. She also reveals the Moon Cell sent her on a mission to stop Kiara, and she was instructed to disappear upon its mission. She offers to save Meltlilith's Spirit Core as cube and reuse as a Servant to help humanity. Once that process is done, Meltlilith can be summoned as a Heroic Spirit that is essentially a new her while the current her will cease to exist. Meltlilth accepts, and disappears with the promise Ritsuka meet her again. With the destruction of Kiara, the Servants are released, and BB rayshifts Ritsuka back to Chaldea. They arrived back, but Da Vinci tells them Seraphix was dismantled at the beginning of the year, which makes think what transpired was a dream. However on their way to their room, they run into BB. She reveals what transpired was processed as a void phenomenon. She then decides to join Chaldea to repay Ritsuka for their help.

Some time later, Ritsuka is sent back to SE.RA.PH by BB to help her save the world. They are then contacted by different version of BB, who congratulates them on their victory over Kiara. She reveals herself to be BB/GO, and that she has taken full control of SE.RA.PH. She then tells her plan to patch SE.RA.PH into the internet, and use Earth's factories to mass-produce BBB robots to conquer and imprison humanity. After her robot capture humanity, she'll use their brains as bio-processors, then connect their minds to SE.RA.PH so they can all worship her. She reveals she was salvaged from Kiara, and BB is a copy of the original sent from the Moon. She continues she'll use the slot machine BB used to mess with Ritsuka and the others, which was actually used to keep Kiara in check. She then reveals she captured Nero, EMIYA, and Tamamo, and turned them into Sentinels. She explains Ritsuka will need to defeat them to unlock the central area where she is. After BB/GO ends her transmission, BB explains she sent by the Moon Cell to prevent Kiara's transformation into Beast III. She continues that during the Moon Holy Grail War, Kiara absorbed Meltlilith, Passionlip, and BB. After becoming a god of pleasure, Kiara salvaged them from herself to serve her. While Meltlilth and Passionlip rebelled, BB redefined herself as BB/Go, and pretended to be loyal. BB then reveals she was asked by BB/GO to manage SE.RA.PH while she hides at its bottom until she regains to strength needed to defeat Kiara. She also reveals she knew BB/GO would conquer SE.RA.PH once Kiara was defeated. Some time afterwards, Ritsuka free Nero, EMIYA, and Tamamo from BB/GO's influence. Everyone then goes to the central area, and defeat BB/GO. After she merges with BB, they all return to Chaldea.

Agartha: The Mythical Subterranean Society
Agartha: The Mythical Subterranean Society, alternatively The Woman of Agartha (アガルタの女) or Subspecies Singularity II (亜種特異点 II), was the second of four major Singularities which emerged in the aftermath of the Human Order Incineration Incident. It occurred in Central Asia in A.D. 2000.

Setting
Engineered by surviving Demon Pillar Phenex and Scheherazade, the Agartha Singularity is situated in a vast underground space in Central Asia in 2000 AD. Created through Scheherazade's story-based Noble Phantasm, Alf Layla wa-Layla, enhanced through Phenex's power, the Agartha Singularity is an invasion of fiction into reality.

Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses
Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses, alternatively the Tournament of the Seven Blade-Master Heroic Spirits (英霊剣豪七番勝負) or Subspecies Singularity III (亜種特異点 I), was the third of four major Singularities which emerged in the aftermath of the Human Order Incineration Incident. It occurred in the Shimosa province of Japan in A.D. 1630.

Setting
Although initially designated as a Singularity and bearing considerable similarities to one, Shimosa is not a proper Singularity in the sense of the Human Order. Described as an otherworld (異界) and subsequently designated as a Subcategory Parallel World (亜種並行世界), it is a timeline which exists between dreams and reality, distinct enough that it should be designated for culling but hasn't been. Due to its isolated nature, the Counter Force is apparently somewhat weaker there, though as it is not within the standard Tree of Time (but at the same time, not within another universe), the events within should not be able to threaten the Tree.

The interior is comprised of the Shimosa province of Japan in the year 1630 during the early part of the Edo period. Unlike the normal world, its capital city is built around the Castle of Toke and the Matsudaira clan resides in the castle.

As opposed to entering via rayshifting, Ritsuka Fujimaru was transported inside via dreams.

Salem: Taboo Epiphany Garden
Salem: Taboo Epiphany Garden (禁忌降臨庭園セイレム), alternatively Salem of Heresy (異端なるセイレム) or Subspecies Singularity IV (亜種特異点 IV), was the fourth of four major Singularities which emerged in the aftermath of the Human Order Incineration Incident. Engulfing present day Salem, Massachusetts, it recreated the events which occurred in the town in A.D. 1692.

Setting
The Singularity recreated Salem, Massachusetts in the year 1692.

Lostbelts
During the interrogation of Chaldea's staff and the arrival of the new director Goldolf Musik, Chaldea was attacked by the and Anastasia, a Servant from the Lostbelts. Being weakened and with the betrayal of Koyanskaya‎ and Kirei Kotomine, the survivors were forced to flee the facility, fast being rendered inoperable and uninhabitable. Before Chaldeas was fully sealed, it was noted that no celestial bodies other than the Earth were visible.

As the survivors escaped in the Shadow Border, meteor-like objects descended from the sky and the world was frozen over. A broadcast on frequencies normally used by Chaldea then began, from Kirschtaria Wodime, a member of Chaldea's A-Team. He declared a rebellion against the Greater History of Man, deeming that their growth was not correct, and that the World would be filled with mysteries beyond the reach of Man and be regressed into the Age of Gods. He further declared that gods would descend from distant skies for this purpose and through seven seeds, leaders would be selected to remake the planet, with those from the Greater History of Man not permitted to participate or observe, frozen and brought to an end as of 2017. Calling himself the representative of the seven Crypters, he ended by announcing to the survivors of Chaldea that the history of the planet would be succeeded by them.

Unable to rayshift with the loss of Chaldea, the survivors were forced to use an experimental method to navigate through imaginary number space and the Lostbelts, in order to resolve the incident connected to the Filtering Outsider Phenomenon (濾過異分子現象).

Anastasia: Permafrost Empire
Anastasia: Permafrost Empire (永久凍土帝国), alternatively Princess of the Land of Beasts (獣国の皇女), Lostbelt No. 1 (ロストベルト No. 1) and the Russian Lostbelt (ロシア異聞帯), is the first of the seven known Lostbelts. Originating in Russia, 1570 A.D., it's Lost Depth is D and it's associated Crypter is Kadoc Zemlupus.

Setting
This Lostbelt diverged from that of Greater History of Man in 1570 AD when an asteroid struck and plunged the world into an ice age. Most humans died, and while Russians were used to the cold and prepared for such weather, 90% of their population perished and they were on the cusp of extinction. Ivan the Terrible and his mages were able to save the country by combining humans with magical beasts, creating the Yaga, with Ivan himself becoming the first. The D Rank Lost Depth here is caused by the Eternal Winter and humanity all but extinct (still alive but as Yaga).

Götterdämmerung: Eternal Ice-Flame Century
Götterdämmerung: Eternal Ice-Flame Century (無間氷焔世紀), alternatively ■■■ of the Unfading Flame (消えぬ炎の■■■), Lostbelt No. 2 (ロストベルト No. 2) and the Norse Lostbelt (北欧異聞帯), is the second of the seven known Lostbelts. Originating in 1000 BC, it's Lost Depth is B+ and it's associated Crypter is Ophelia Famulthorone.

Setting
The Lostbelt diverged from the Greater History of Man in 1000 BC, during the events of. Surtr, who was supposed to bring the Twilight of the Gods, devoured, gaining his Authority and becoming immensely powerful. He decided to bring about the Twilight of the World, killing many gods and giants before being sealed within a false Sun by Odin, who died afterward. However, before dying Odin merged the goddess Skadi with Scáthach, creating Skadi-Scáthach, the King of the Lostbelt, with the purpose of protecting the humans. As Ragnarok was thus interrupted, the world became ravaged by fire and ice, unable to continue past Ragnarok.

Skadi-Scáthach established multiple villages for humans, with the support of the Valkyrie. However, in order to keep the giants at bay, humans are required to reproduce at the age of fifteen or be sacrificed to the giants. Once humans reach the age of twenty-five they are nonetheless forced to be sacrificed. The B+ rank Lost Depth is caued by Earth no longer having humans with the remainder forced to live in the Realm of Shadows. Also, the Realm is only capable of maintaining a few hundred humans before collapsing as such, humans who fail to reproduce at 15 or reach the age of 21 are sacrificed to both appease the giants and maintain the Realm.

SIN: Land of Unified Knowledge
SIN: Land of Unified Knowledge (人智統合真国), alternatively Crimson Beauty Under the Moon (紅の月下美人), Lostbelt No. 3 (ロストベルト No. 3) and the Chinese Lostbelt, is the third of the seven known Lostbelts. Originating in 210 BC, it's Lost Depth is E and it's associated Crypter is Hinako Akuta.

Setting
The Lostbelt diverged from the Greater History of Man in 210 BC, during the end of the reign of Qin Shi Huang. Qin Shi Huang, during his search for an elixir of life, discovered the artificial body of Nezha, which he used to develop technology that allowed him to continue existing in an artificial form. This method allowed Qin Shi Huang to continue ruling China forever. Due to his “immortality” and technological equipment, he eventually managed to conquer the whole world after years of wars, dubbing this new empire as the Eternal Sin Empire.

After his conquest was completed, Qin Shi Huang created a planetary defense system that surrounded the whole Earth, called the “Great Wall”, which allowed him to monitor everything in the world. Despite the advanced technology in his control, the common folk were kept uneducated, with no access to this technology. Thus, the society of the empire remains at a basic farming level. However, the people live in complete peace, with no conflicts occurring over hundreds of years. Qin Shi Huang also artificially “froze” many of the greatest warriors that emerged over the years, so that their talents could be used at a later date. This includes Xiang Yu, Qin Liangyu and Han Xin.

The E-Rank Lost Depth is very low due to humanity not being in any danger. The main divergence is due to technology stagnation amongst everyone other then Emperor Qin.

Yuga Kshetra: Genesis Destruction Cycle
Yuga Kshetra: Genesis Destruction Cycle (創世滅亡輪廻), alternatively Black Final God (黒き最後の神), Lostbelt No. 4 (ロストベルト No. 4) and the Indian Lostbelt, is the fourth of the seven known Lostbelts. Originating in 11900 Deva Vatsara, it's Lost Depth is A and it's associated Crypter is Scandinavia Peperoncino.

Setting
The setting in this lostbelt is that during the events of the ending of the Mahabharata, Arjuna absorbed all of the Hindu Gods starting with Krishna. By becoming Arjuna (Alter) he became a living god with a skewed personality. He then decided that as a perfect being he must also live in a perfect world befitting the God that he is. Originally the Yuga System in Hindu Mythology will cause the destruction and reincarnation of the World and takes place in a very long time (after several millennia) however due to Arjuna (Alter)'s impatience, it is occuring on a weekly basis instead.

While doing this, any person who even has the tinest bit of "evil", or "considered to be evil" by God (Arjuna Alter) would be killed, no exceptions. Even worse, those people cannot reincarnate and will be forever forgotten. The destruction and recreation of the world is also messed up because it's not a complete blank start-over like in Hindu myth, but the reshaping of the world by slowly removing elements that is deemed to be imperfect by God. To live in this world and considered to be good, you only need to pray to God everyday, obey everything God wants and you don't need weapons or fighting. If you fail, you are considered to be evil and thus holy beasts and Kali will come and attack, begin the Yuga cycle to remove the "evil".

Arjuna Alter wants to first create the perfect world then extend it to the entire galaxy. According to Ashiya Doman, once the Major Yuga is in effect, that would be the end of the universe and the trichiliocosm.

The A-Rank Lost Depth in this Lostbelt is due to Arjuna Alter speeding up the Yuga System to a weekly reset. For the Lostbelt king only those who are deemed worthy will reincarnate next cycle, he is slowly eliminating people from existence, including memories and actions.The problem is that the king is an amalgamation of gods, the "perfect and purest being" so he will never find anyone really worthy except himself. With this, the numbers of living humans are decreased with each reincarnation cycle because the king eliminated those who deemed unworthy, until no human remains and humanity would perish eventually.

Other
During the Human Order Incineration Incident and the events afterwards, Chaldea also tackled a number of distortions and incidents other than the designated Singularities and Lostbelts. These included space-time distortions which would have become fully fledged Singularities if left unchecked, certain events in alternative timelines, places visited through dreams and others.

Kara no Kyoukai: The Garden of Order
Kara no Kyoukai: The Garden of Order, also known as Ogawa Heim, refers to an event, part of a collaboration between Fate/Grand Order and Kara no Kyoukai, which occurred during the Human Order Incineration Incident. It involved a distortion which would have become a Singularity if left unchecked, located in Mifune City, and based around the Ogawa Apartment Complex.

Setting
The distortion occurred in Mifune City near and within the Ogawa Apartment. After Solomon recovered it from the incinerated history, he ordered Edmond Dántes to turn the distortion into a Singularity, and bestowed upon him a system of curses to serve as the core. Additionally, Solomon summoned Mephistopheles to assist him, and separated the demon's good self from his evil self. However, Edmond, not sharing Solomon's goals, decided to transform the distortion into an eternal hell to fuel his need for vengeance. He ordered Mephistopheles to infiltrate Chaldea and convince Servants to come to the apartment. After the Servants rayshifted to Ogawa, their personalities were soon altered by the building's bizarre nature. Moreover, the resentment that the Servants felt attracted spirits of the dead to the apartment. In turn, the spirits were drawn into the core of the would-be Singularity with their resentment strengthening it. Before the arrival of Ritsuka Fujimaru and Mash Kyrielight, Shiki Ryougi was summoned into the distortion due to her connection to the apartment.

History
Ritsuka and Mash arrive in the distortion near the Ogawa Apartment Complex, where Ritsuka's Servants are located after they rayshifted into the distortion. They soon notice a Servant fighting ghosts and go to help her, but the ghosts are all eliminated when they get there. Mash tries to talk to the Servant, but she refuses and attacks her and Ritsuka. The battle ends in an interruption however, but Romani Archaman informs Ritsuka and Mash that the Servant possesses the Mystic Eyes of Death Perception. The Servant then apologizes for attacking the pair and starts to leaves. Ritsuka stops her however, and she tells them that she's going to tear the apartment down to stop the undead within from spreading out to the neighborhood. She continues that the undead are running rampant in the apartment due to Servants living there. The Servant tells Mash and Ritsuka that she is a Pseudo-Servant and that she was summoned into the Singularity possibly due to her connection with the building. She then tells them her name is Shiki Ryougi, and after learning their names, she decides to help them. Asked by Romani of the apartment's condition, Shiki states that it is merely filled with enemies and traps. She and the others then enter the apartment.

Entering the apartment, the group investigate the first room, which is oddly cold despite the thermometer showing regular temperature. Shiki points out Musashibou Benkei's presence in the room. Mash tries to talk to him, but he attacks the groups saying they abandoned a respectable way of life. After defeating him, Romani explains that as a Servant contracted to Chaldea Benkei will eventually return there. Shiki then explains that what happened to Benkei has happened to every tenant before, and tells Ritsuka that they did the right thing in defeating Benkei.

Continuing their investigation, Mash asks Shiki why the apartment is cold, why the dead walk, and if the apartment is Mage's Workshop built in secret. Shiki explains though that the apartment was publicly built without any Magecraft involved. She continues the apartment was built to collect the death of its residents, who are reborn when morning comes and die when night falls in an endless loop. Afterwards, Shiki unlocks Room 102, and she enters the room with the others. Inside they are greeted by Mephistopheles, and claims that he lured Ritsuka's Servants to the apartment. He then attacks the group after explaining he took the room's previous tentant's role of cutting bodies apart. After his defeat, Mephistopheles tells the group to solve the mystery and seemingly disappears. But, before the group continues their investigation however, Mephistopheles reappears to everyone's shock. He explain that the one they defeated was evil him and the current him is the good version. He reveals that he has nothing to do with the current situation when asked by Romani, and reveals he was summoned to the apartment by Solomon. Mephistopheles continues that Solomon split him into two, and states his evil self infiltrated the Chaldea and convinced the Servants to come to the apartment. He then says that he escaped from Solomon's contract and waited for the group's arrival. Now joined by Mephistopheles, the group continue their investigation.

Continuing to explore the apartment, Shiki talks about how it is collecting stuff unrelated to its original design and turns it evil. Mephistopheles compares the apartment to a hollow tree from which one will fall into the eternal abyss if they're unlucky when peeking into it. He then asks about Shiki's Mystic Eyes, to which she briefly explains their function. Suddenly, Henry Jekyll appears and asks Mephistopheles if the others are the new tenants. He tells the group that he is the manager of the corridor, and says as new arrivals they haven't mutated. Jekyll advises them to stay on the first floor a little longer, and invites them to stay in his room. However, the group reject his invitation, which he responds to by turning into Mr. Hyde and attacks. Shiki block it however and complains how Hyde isn't strong enough for her. Enraged by her statement, he fights her and the others but is defeated. Returning to normal, Jekyll apologizes for his transformation, and claims he and Hyde were manipulated. He warns Ritsuka not to trust Mephistopheles, and prepares to hand them the key to the next floor. However, he changes back into Hyde and attacks Ritsuka, but he's blocked again by Shiki, who takes the key from him. She complains she wanted to meet Jekyll, and reveals Hyde was the only personality and he was only pretending to possess dual personalities. After Hyde disappears, Mephistopheles reveals Jekyll mutated upon his arrival at the apartment, rotting his body and soul away until his main personality vanished. Asked by Mash, he explains the Servants are being affected by the resentment in the apartment and their alignments are changed as a result. Afterwards, the group move to the second floor.

Entering a room on the second floor, the group encounters Elizabeth Bathory. She threatens to sever Ritsuka's hands and feet and burn their internal organs before attacking the group. After being defeated, Elizabeth complains of her misery and humiliation before finally disappearing. The group then moves to the next room after receiving a transmission from Da Vinci regading Elizabeth's return to Chaldea.

Investigating a room on the third floor, the group encounters Boudica. She welcomes Ritsuka and Mash, and asks them if they're here to bring her back to Chaldea. Boudica scolds them for not ringing the door bell first, and offers Ritsuka to have some stew she recently made. However, when Mash says they'll bring her back to Chaldea after eating, Boudica suddenly turns aggressive. She refuses to return to Chaldea, amd angrily states how the Romans took everything from her. She continues that she forgotten about it by distracting herself with saving humanity, then she attacks the group. After being defeated, Boudica realizes what she did and states the irony of how title of Queen of Victory despite losing the battle most important to her before disappearing.

Nearly complete with their investigation of fourth floor, the group are confronted by Artoria Alter. She warns them to leave as the floor above is filled with vengeful ghosts. The group prepare to fight, believing her to be the mastermind behind the incident. However, Mash and Mephistopheles' misconception about her appearance cause her to remove her armor. She tells them that if she'll forgive their disrespect if they can survive and prove their bravery to her before fighting them. After being defeated by them, Artoria Alter realizes that Shiki has the Mystic Eyes of Death Perception. She states the group should be fine going forward as along as Shiki is with them. Artoria Alter tells them that she has been weeding out those who can't handle the grudges of the apartment, but she know they'll survive if Shiki is with them. She also tells them that she came to the apartment of her accord, and reveals Solomon attempted to convert the apartment into a Singularity after recovering it from the incinerated history. She also reveals this plan failed as Solomon sent the wrong job to do the job, which resulted in the apartment becoming a tower that attracts and imprisons Servants, converting them into demons. Artoria Alter then warns that the apartment will someday become the Singularity called "Hell", though she states it has no bearing on the incineration of humanity. Deciding to rescue the remaining Servants, the group continue their investigation.

Later, Ritsuka has the group investigate outside, where Shiki senses a presence. Suddenly, a Servant surrounded by darkness appears before them. He asks the group who they are and why they're killing ghosts. He continues that the ghosts are souls who were unrewarded in life, and their regrets kept them from moving to the afterlife. The Servant states that the ghosts need peace, saying that if Hell denies them he'll create a Hell by using the grudge filled apartment. He then tells the group not to stand in his way and leaves. After he leaves, the group are suddenly confronted a ghost different from the others. Mephistopheles warns Ritsuka that the ghost reaching a state near that of Primate Murder, and states they're all going to die now. However, Shiki states that they would be dead if the ghost was a real Monster of Gaia, and reveals that it is a defective Monster of Alaya. She then tells the group to fight the ghost, and suddenly reintroduces herself with a new appearance to Mash's confusion. Shiki tells them that she didn't want to reveal herself but had no choice given their opponent, which further confuses Mash. After destroying the ghost, she returns back to normal after tripping over a tree root. She mistakes the victory as Ritsuka and Mash's, but Mash corrects her. Cath Palug then gives a key to her that he found.

Back in the fifth floor of the apartment, the group are told by Romani that the core of the Singularity is nearby. Entering the room where the Singularity's core is located, they welcomed by another evil Mephistopheles. Mephistopheles reveals that behind his evil self is a greater ghost called the Great Avici Hell, which draws in spirits and turns them into a pillar. Evil Mephistopheles asks Ritsuka why they're rescuing the Servant since they changed of their will, and says the distortion is safe to ignore since it's a fake Singularity. He continues that even if humanity's foundations are restored, the distortion will continue to exist outside the world and continue gathering hatred and pain. Ritsuka answers they couldn't ignore the suffering inside the apartment, which evil Mephistopheles responds to by attacking the group. After the enemies are destroyed, Mephistopheles disappears as his evil self was destroyed, saying he had fun and bids farewell to everyone. Afterwards, Shiki states the apartment will return to its original abandoned state with the ghost gone. She then returns to Chaldea with Ritsuka and Mash.

The group return to the apartment to return the rest of the Servants to Chaldea. They enter a room on the sixth floor with very brights, where they encounter Frankenstein and Lu Bu. Frankenstein tells them how Nikola Tesla caused a power outage when he used his Noble Phantasm, so she also decided to waste to start wasting electricity. Lu Bu tells them that he helped her because Frankenstein looks like his daughter. Taking note of complaints about frequent outrages, Shiki and the others fight the room's tenants. After they're defeated, Frankenstein and Lu Bu return to Chaldea; she decides to unplug any device of unknown to converse electricity. Shiki reveals she got a request to resolve the cause of the power outages after Mash asked about her memo pad. She says her next request to remove a tenant who refuses to pay rent, and reveals the requests are for removing Servants living illegally in the apartment. She continues that her family owns the building, so she came to the apartment on their behalf to collect rent. Shiki then requests Ritsuka and Mash with eviction of the remaining Servants.

Following the complaints on Shiki's memo pad, the group start evicting the Servants from the apartment. They discover Anne Bonny and Mary Read refuse to pay rent after becoming internet addicts thanks to Blackbeard, so the pirates are removed from the building. Cú Chulainn is doing a illegal gambling, and with Scáthach's help, he is evicted. The group find that Oda Nobunaga and Okita Souji's room has been warped by the former's Reality Marble, which is returned to normal after she's defeated. The group evict Leonidas, who was trapped in a room due to his fear of ghosts. They discover Mysterious Heroine X had crashed into the apartment to continue her hunt for Sabers, which prompts Shiki to switch personalities and fight her. After X retreats, Shiki returns to normal with no memory of what transpired. She then tells Ritsuka and Mash that all of the Servants have been finally removed from the apartment.

Later, the group access the roof through the emergency exit, which Shiki unlocks with the key Cath Palug gave her earlier. There they confront the mysterious Servant, who they believe to the mastermind behind the distortion. He tells them that his grudge shall never fade away, and even if the apartment will disappear, his work will continue. He refuses to give up until he remembers everything of the island of despair, the tower of incarceration, and the castle of treasures. Mash calls him a Heroic Spirit that shouldn't exist in this world, but he refutes that Heroic Spirits and spirits of the dead are both curses. Then, the greater ghost the group destroyed earlier appears, which Mash believes to be another one. The Servant corrects her by saying that curses never disappear, and states the system of curses that Solomon given to him is now complete. He continues that resentment and killing will continue as long as other exists, and states the hatred of the sacrificed are his nourishment. After he states he'll be worshiped as a god for creating an eternal hell, the greater ghost prepares to attack the group. Mash senses that it has far more Magical Energy than before, and states its resentment increases with every defeat. She warns that if the ghost's resentment continues to increase at its current rate, they won't be able to destroy it. However, Shiki encourages her and Ritsuka to fight, even stating to the Servant that all things have an end. Impressed by her claims, he asks the group to show him that they can deny the evil of humans, and prove to him nothing can exist for eternity.

After the ghost is destroyed, the Servant starts to flee by jumping off the roof. Shiki goes to stop him, but Romani warns that the Servant is actually an illusion. Ritsuka stops her, and she kills the illusion of the Servant with a thrown knife. As he disappears, Romani asks him why he created the distortion and who ordered him to do so. The Servant answers he was ordered by Chaldea's enemy to transform the apartment into a Singularity. But instead he used it to fuel his need for vengeance by using the Servants' own desire for revenge. Ritsuka then asks the Servant for his identity before he disappears, but he only answers by saying "Attendre et esperer... (Wait and hope)". After he disappears, Romani informs the group that the distortion will eventually disappear. Mash, however, is curious about the mysterious Servant's identity, and wonders if they'll fight him again. Shiki tells her that he may become an ally, even saying he is someone with great love and hatred for humanity. With the distortion now resolved, the group return to Chaldea.

Vengeful Demon's Wail at the Prison Tower
Vengeful Demon's Wail at the Prison Tower (監獄塔に復讐鬼は哭く) refers to an event which occurred during the Human Order Incineration Incident. It involved an incident where Ritsuka Fujimaru's soul was summoned into a recreation of within a different time and space.

Setting
Back when Ritsuka Fujimaru first encountered Solomon in London, the latter placed a cursed on the Evil Eye called on them when they stared in his eyes. The curse was activated at a later date when Ritsuka carelessly said Solomon's name. This caused their soul to be summoned into a recreation of the famed prison tower, Château d'If, within a different time and space that Solomon uses as a hunting ground. As well several Servants, whether they were contracted to Ritsuka or not, had fragments of their soul separated from them and trapped inside the tower. There they would serve as the seven avatars of sin that Ritsuka must overcome to escape, which must done in seven days otherwise they will die. However, Florence Nightingale, lost her original role as the avatar of pride for unknown reasons along with her memories, so the role was taken by Edmond Dantés instead.

History
Ritsuka suddenly find themselves inside a prison cell. They are welcomed by a mysterious voice, who tells them their soul is no exception to being prisoner in the tower. The voice also reveals that neither Mash Kyrielight, Romani Archaman, nor Leonardo da Vinci can help them. The origin of the voice then appears before Ritsuka, and states how all the spirits of the tower are coming to kill Ritsuka out of envy. After the mysterious person kills a spirit, Ritsuka demands to know who the person is and where they are. He answers that they're in the prison tower, Château d'If, and introduces himself as Avenger. After exiting the prison cell, he tells Ritsuka to survive the ordeal if they wish to learn more. He says though he isn't no obligation to teach them how to obtain the prison's secrets, even threatening to beat them. Stating that he'll teach them the minimum however, Avenger reveals to Ritsuka that their soul has been imprisoned. He continues that in order to escape they must pass the seven Halls of Judgement, and states neither their voice nor Chaldea's can reach either. He warns that getting killed in the Halls of Judgment means death in reality, and idling for seven days also means the same thing. Avenger also reveals that the Château d'If they're currently in is very different than the historical one. He states that it is similar to the Singularities yet it is something else, calling it hunting ground created by Solomon. Moving forward, Avenger introduces Ritsuka to Phantom of the Opera, the first of the seven lords that must be overcome. He calls him a monster of envy that has come to kill Ritsuka. Phantom notices Ritsuka and tries to kill them for not being Christine. After being defeated by Ritsuka and Avenger, Phantom sings of Christine, in which he reveals his envy towards society. After Avenger finishes him off, Ritsuka suddenly find themselves back in their room in Chaldea. There they are greeted by Phantom, who tells them that only one can protect them in the prison even if they're not necessarily good. Ritsuka asks him how he's alive, to which he replies that the one killed in the tower was his ultimate ugliness. However before Phantom can reveal anymore, Ritsuka is summoned back to Château d'If.

Back in Chaldea, Mash tells Ritsuka about the history of Château d'If, but they're summoned back to the tower before she could say anymore. There Avenger addresses Ritsuka's concerns, revealing that Mash is still in Chaldea and so is their body. He continues that the flow of time and space is different between the two locations, and states that seven days in the tower may be a single day in Chaldea. Avenger then reveals that he and Ritsuka will always begin in the prison cell before exiting the cell. Outside, the pair find a mysterious woman asking for help. She tells them that she suddenly woke up in the prison, saying she can't remember anything. After The woman remembers she was looking for something important, Avenger decides to have call herself Mercédès. He then asks Ritsuka what they'll do with Mercédès, to which they answer that they'll take her with them. Reaching the second hall, Avenger asks Ritsuka if they have ever felt lust, to give in to their bestial urges to touch another. Suddenly Fergus loudly answers Avenger's query, and he decides to take Mercédès as his own. He then tries to kill Ritsuka and Avenger, believing they're trying to kidnap Mercédès away from him. After defeating Fergus to protect Mercédès from him, Ritsuka returns to Chaldea before a concerned Mash and Fergus who just entered the room. Mash asks him to help her take Ritsuka to the medical room, but he says there is no point. Suddenly though, Ritsuka is summoned back to the tower and is congratulated by Avenger for overcoming the Hall of Lust. Then, Deciding to take Mercédès with them, Ritsuka and Avenger continue to the next hall.

Back in Chaldea, Ritsuka is unresponsive to Romani, who states he and Da Vinci will continue diagnosing and analyzing. Romani and Mash then wonder what Fergus knows about the situation, only saying there was nothing they could do from their end. Back in the prison, Ritsuka is greeted by Mercédès after they woke up. Avenger then greets them and asks if they have ever felt slothful, which he criticizes them as being so now. After Mercédès defends them against his claims, Avenger reveals that the connection between Ritsuka's body and soul is weakening. Exiting the cell and leaving Mercédès, they move to face off against the avatar of sloth. Once there they are confronted by Gilles de Rais, who is spouting about how his blasphemy is an offering to God. Avenger answers Ritsuka that Gilles is sloth because he let his soul rot, even calling him the worst of humanity. After Gilles says he'll torture their soul into despair, Ritsuka and Avenger fight him. After he is defeated, Gilles apologizes to Ritsuka back in Chaldea for a fragment of him troubling them in the prison tower. However he believes they'll escape the prison as long as the light of their soul never extinguishes.

Inside Ritsuka's room, Jeanne d'Arc begins to tell them a story of a man and vengenance. Meanwhile in Château d'If, Mercédès tells them not to aggravate Avenger as he seems to be angry about something. Avenger then comes in and immediately has Ritsuka go to the fourth hall with him. Outside of the cell, Avenger tells them that they'll face against wrath, which he calls the strongest emotion, saying all humans love revenge stories. Suddenly, he becomes enraged about how despite playing the role of the avatar of wrath, she still speaks of salvation and forgiveness. He calls such a thing unforgivable, saying he'll never forgive even if God and people do. Moving on to the fourth hall, Avenger is greeted by Gilles de Rais, calling him the enemy of the righteous, and states how he'll cut him down in the name of his Holy Maiden. After Avenger reveals Jeanne to be the avatar of wrath and calling her a fool, he reveals she came to the tower willingly to stand against him. Jeanne admits his words are true, saying she has come to stop him. Avenger then answers Ritsuka that she is wrath because she believed in humanity and God, only to be betrayed and burned at the stake. Jeanne however denies his claims, and says she will not judge Ritsuka as she lack the right and the will to do so. She continues that it doesn't matter that she didn't manifest in the tower properly, she will try to save Avenger's soul. He angrily replies by telling her to repeatedly shut up, to which Gilles responds by preparing to fight him. Jeanne however, wanting save Avenger's soul, tells him to stop. But, Gilles tells her that his soul is beyond salvation, and Avenger agrees with his assessment as neither Hayede nor Abbe Faria is with him. After he tells Rtisuka that they can't save him either, Jeanne decides to finally fight him with Gilles.

Afterwards, back in Ritsuka's room, Jeanne continues her story from before. She says the man was sailor in Marseille, who was happily betrothed to a beautiful woman. However, he was falsely convicted and sentence for treason, betrayed by an old friend of his. The man was secretly sent to a prison tower in the bay of Masrseille, the Château d'If, from which none return alive. There the man experience a living hell until he was given hope and guidance by an ancient wise man imprisoned there named Abbe Faria. After Abbe died, the man escaped the prison by taking the place of Abbe's corpse in its bag. Fourteen years had passed when he finally escaped, then with the treasure of Monte Cristo, the man began his revenge on those who forgot and betrayed him. Jeanne calls the story a very cruel and brutal one, but notes how people applauded the man for bringing righteous wrath against evil. Jeanne then says the man called himself the Count of Monte Crisco, who became the world's most famous seeker of vengeance after abandoning all of the good in his heart. However before Jeanne can reveal his name, Ritsuka returns to c, where Avenger is preparing to finish Jeanne off. She admits her defeat, but says she'll stop him and all his plans before leaving. Avenger then tells Ritsuka that he is taking to a place beyond love and hate, wondering if they'll return from there alive or go mad there.

In the prison cell, Mercédès tells Ritsuka that Avenger had just left saying he was scouting outside alone. She then to wonders how she became trapped in Château d'If, believing she may have been chosen as a avatar of a sin. Mercédès then contemplates if humans can exist without sin, and wonders if anyone but God can judge sinners. Avenger then returns and immediately has Ritsuka go with him to fifth Hall of Judgement. Outside the cell, Avenger tells them that they'll be facing the avatar of Gluttony, who he notes will be an easy opponent. Entering the hall, the avatar is revealed to Caligula, who goes to kill Ritsuka. Back in Chaldea, Caligua expresses his belief in Ritsuka prevailing as even he became a Heroic Spirit instead of an Anti-Hero.

Inside the prison, Ritsuka and Avenger go to face off against the avatar of greed. At the sixth hall, they are confronted by Jeanne, who had been waiting Avenger. She says that she will defeat him this time, believing it the only way to save him. Avenger angrily tells her to get out his way, to which she says even with all his wrath he can still receive forgiveness and salvation. However, he denies her words and calls himself the Count of Monte Cristo. Meanwhile in Chaldea, Jeanne reveals the man from her story from before is named Edmond Dantès, who also called himself the Count of Monte Cristo.

Back in the hall, Avenger prepares to kill Jeanne, who is told by a voice that some feelings cannot be shared with mere words. However she refuses to give up, and the voice reveal themselves to be Amakusa Shirou Tokisada, the avatar of greed. Shirou greets Avenger and tells him that he believes in him to the latter's confusion. He tells him that he should know what is truly valuable if he experienced a living, and notes how he didn't join Solomon. However, Avenger tells him that he has no interest in Solomon as he is without hatred, and says that he himself never helped save the world. Shirou admits the truth of Avenger's words, then asks for Jeanne to help fight him, who gladly accepts. After they're defeated by Ritsuka and Avenger, Shirou regrets that he and Jeanne couldn't save him, and tells him that his black flames of vengeance will destroy him as well. Avenger says he is an eternal avenger not even God can stop, but Jeanne tells him nothing is eternal particually evil. Avenger denies her words and states that her and Shirou's weakness is what trapped them in the tower as avatars of wrath and greed. He admits that he would have trouble against their true forms, then he says goodbye after admiring they kept their nobility even inside the prison. Before disappearing, both Jeanne and Shirou pray that Avenger's soul will find rest somewhere far from the prison. Afterwards, Ritsuka and Avenger return to their cell after he wonders if Ritsuka would have been saved or trapped if he was defeated.

Inside the cell, Avenger asks Ritsuka where Mercédès is. Ritsuka answers she may be in the Hall of Judgment, but Avengers says she may be in another part of the prison that Ritsuka doesn't know of. Despite that though, he and Ritsuka go to the final hall. There they find the hall to be empty, so Avenger decides a story, the same Jeanne told, to pass the time. Suddenly, Mercédès appears to stop him with help of the wraiths of Château d'If who admire her. Afterwards, in Chaldea, Mercédès reveals to Ritsuka that she was meant to be the seventh Lord of Judgment, but instead lost the role along with her memories. Back in the prison, Mercédès admits she isn't the real one but wishes for Avenger to find peace, calling him Edmond Dantès. After she disappears, Avenger angrily denies that he is Edmond, which makes Ritsuka realize that it is his True Name. Edmond congratulates them for overcoming the seven Halls of Judgement, but he decides to fight them as only one may leave Château d'If, revealing himself to be the avatar of pride. After he is defeated, Edmond is impressed by Ritsuka's victory, and says he is content that he could be like Abbe Faria for once. Edmond then states how he knew of victory, even after he achieved his revenge unlike the Edmond from the story. After expressing his gratitude towards Ritsuka, he reveals that Solomon was the one who trapped them in the prison tower. He continues that Solomon placed a curse called the Evil Eye on Ritsuka when they stared into his eyes back in London. Edmond is impressed that they were able to overcome Solomon's trap, and tells them to "wait and hope" for their next meeting. After he disppears, Ritsuka is finally returned to reality.

Fate/Accel Zero Order
Fate/Accel Zero Order refers to a an event, part of a collaboration between Fate/Grand Order and Fate/Zero, which occurred during the Human Order Incineration Incident. It involved a small Singularity that manifested in the coordinates of Singularity F in an alternate timeline ten years prior during the Fourth Holy Grail War.

Setting
The Singularity shares a similar background to the Fourth Holy Grail War of the original timeline but with significant differences. Firstly, Kiritsugu Emiya and Irisviel von Einzbern have never met each other nor was he hired by the Einzberns to serve as Artoria Pendragon's Master. Instead she become a proper Master in the war with Artoria as her Servant while he contracted with the World to become a Counter Guardian. So unlike the original Fourth Grail War, the Einzberns prove to be the superior faction. However, the Counter Force sensing that the Einzbern's victory will cause the activation of Angra Mainyu, summons Kiritsugu to stop the war before its completion.

History
Arriving in Fuyuki, Ritsuka Fujimaru, Mash Kyrielight, and Lord El-Melloi II discuss the disaster that will come to the city with the Holy Grail War. Before the discussion goes further though, El-Melloi performs Qi Men Dun Jia reveal the concealed Hundred-Faced Hassan. He reveals that he planned to catch themselves in Hassan's city-wide surveillance network, knowing they would investigate the rayshift location. After Hassan is defeated, El-Melloi warns that they will be keep attacking the group while surveying the city. Telling Ritsuka and Mash to defeat the other Hassan immediately on encounter, he and the others move onward.

At the wharf, El-Melloi speaks of the deception of the Holy Grail granting any wish to lure in participants. He continues that All the World's Evils will activate if the require number of summoned Servants are sacrificed. El-Melloi compares it to a bomb that could destroy the world, and call Singularity F the result of the ritual being completed. Mash asks who would make such ritual, to which he answers that was the result of a "man-made diaster". El-Melloi tells them the paradox of the Holy Grail having already manifested in Fuyuki yet the city hasn't been destroyed by fire. He theorizes that the Grail detected by Chaldea is different from Fuyuki's Greater Grail that had been corrupted by Angra Mainyu. Then, he waits for Irisviel von Einzbern and Saber to arrive in the area as he knew they would thanks to his knowledge of the fourth war. Irisviel asks the group who they are, believing them to be participants the war. Saber tells her that she no longer detects the presence of Lancer, who had invited them. El-Melloi reveals Saber's True Name to be Artoria Pendragon and has the group fight her.

After Artoria retreats, the group are confronted by Lancer, who was trapped by El-Melloi's Qi Men Du Jia formation to prevent him from fighting Artoria. He reveals Lancer's True Name of Diarmuid Ua Duibhne, and tells him that the group are not Kayneth El-Melloi Archibald's enemies. Kayneth then asks him how he knew he was Diarmuid's Master. El-Melloi tells him that the group has come to support him, and gives the name of Reines El-Melloi Archisorte as his guarantor as he can't divulge his name now. He tells him that he'll reveal more and Caster's current location tomorrow at noon. Kayneth is convinced to leave the group for tonight and reveals himself before them despite Diarmuid's caution. Leaving the wharf, El-Melloi continues his explanation of the activation of Angra Mainyu, and reveals his plan to have at least three Servants withdraw from the battle to prevent the Grail from activating. He continues that the group will seek out and defeat the Servants with whom agreement is impossible. He considers Caster and Archer to be those who won't be convinced, so the group should defeat them before they can engage with any other Servants. He warns that they'll likely have fight Hassan when they confront Archer since their Masters are colluding with each other. El-Melloi then says that they will have to convince Berserker's Master join them since reasoning with Berserker directly is impossible. He warns that Berseker may go on an rampage regardless of his Master's order, and also warns that his Master is unstable physically and mentally. Deciding to postpone convincing Berserker's Master, El-Melloi decides they should focus on convincing Artoria, Diarmuid, and Rider with whom they have the best chance.

Later, Mash is prevented from establishing a summoning circle to get supplies from Chaldea due to the leyline being guarded by a spell placed by the Tohsakas. El-Melloi decides that they must destroy the keystones that power the spell and take the leyline for themselves. Romani Archiman is worried that doing so will anger the Tohsakas, but El-Melloi reveals them to be the ones who summoned Archer. He then leads the group to each keystone, which knows the locations of thanks to Rin Tohsaka when she helped him dismantle the Greater Grail in his timeline. At one of the leyline points, the group by ambushed Sea Demons summoned by Caster in an alleyway. After killing them, El-Melloi goes to negotiate with Kayneth at his apartment while keeping a telepathic line to the Ritsuka. Inside the apartment, Kayneth confronts him with the fact that the he was lying that he was acting on Reines' behalf. However, he decides to continue the meeting due to wanting know more of Caster's location from him. El-Melloi convinces him that he is from the future by stating Kayneth's original intention to summon Iskandar instead of Diarmuid until the catalyst was stolen by Waver Velvet. He also reveals his knowledge that Kayneth's Fiancée, Sola-Ui Nuada-Re Sophia-Ri, to be the one providing Magical Energy to Diarmuid. El-Melloi then tells him that he will be officially be Reines' service four years later from now. Later, he deceives him that Chaldea's technological achievements were all accomplished by the Archibald family, which were only made possible thanks to his leadeship and founding of Chaldea. After convincing Kayneth to join them, the group head to Caster's hideout in the sewers.

In the sewers, the group eventually confront Caster, Gilles de Rais. They defeat Gilles but Ritsuka wonders where his Master, to which El-Melloi warns he is a murderer who they must stop. After Kayneth goes to the Church to get an additional Command Spell, the group search for Gilles' Master. Further in, the group find Gilles' Master's corpse, but El-Melloi suddenly detects a Servant and deploys Qi Men Dun Jia to trap them. The Servant is revealed to be a mysterious Assassin, who El-Melloi believes to be why 1994 Fuyuki into a Singularity or at least connected to the cause. Assassin fails to convince the group to release him since he has no reason to fight them. After they defeat him, the group notice that he is similar to EMIYA in nature. Suddenly, another Servant charges through, allowing Assassin to escape when they destroyed El-Melloi's formation. Iskandar and Waver then stop their movement to confront the group, and El-Melloi argues with Waver over his primitive methods and arrogance. Waver wonders if he is Caster or Caster's Master, which only infuriates El-Melloi further. He reveals to him that he is a Pseudo-Servant to Waver's confusion over the term and there being two Casters. Iskandar tells him that El-Melloi isn't the owner of the workshop they're currently in. He then tries to pick a fight with the group, but they retreat to his disappointment.

Later, Mash finally establishes the summoning circle, but the group is soon confronted by Artoria. She challenges them to a fair fight, which El-Melloi is unconvinced of due to his knowledge of her serving as a decoy while Kiritsugu Emiya ambushes the enemy. As the group continue to fight Artoria, Mash defends Irisviel from Assassin's ambush. He tells Irisviel that he has come to kill her because she is the Lesser Grail, and he wants to kill her due it simply the fastest way to dismantle the Grail. Artoria then fight him to defend her, which prompt the group to aid her to prevent losing her. After they defeat him, Assasin asks the group why they're getting in his way since they're outsiders to the war. In turn, El-Melloi asks him why he is trying to kill Irisviel, but Assaasin refuses to answer and retreats. Artoria then speaks of how she noticed that the group wasn't trying to defeat her, which prompts Irisviel to ask them if they're enemies or not. El-Melloi answers that they wish to keep Artoria safe to achieve the goal, but he refuses to divulge anymore. He then asks Irisviel if she knows who Assassin is, but she doesn't know him other than a vague feeling that he is meant to kill her. Artoria vows to protect her, and is convinced that the group aren't enemies after Irisviel thanks them for saving her.

After making peace with Irisviel and Artoria, El-Melloi decides to deceive Kayneth even further. After defeating the failed ambush of Hassan, the group go to Kayneth's apartment. There Kayneth reveals that Berserker's Master has agreed to join them if they help him defeat Archer. El-Melloi then convinces him that the Holy Grail War is an conspiracy by the Trambelios, the enemy of the Archibalds, to increase their influence in the Mage's Association while he's away. He continues that the Tohsakas confessed in colluding with the Trambelios to create a fake war, and lies that the other participants are decoys. Kayneth then gives Diarmuid to the group after using a Command Spell to stay in Fuyuki and win the war. Outside, Romani warns El-Melloi that his actions in the Singularity will not change what happen in his timeline as it will disappear once it's resolved. El-Melloi replies that his current actions are a result of him wanting to overcome the powerlessness and regret he felt back then. Despite that though, the group continue with his plan and go to meet with Berserker's Master.

Meeting with Berserker's Master, Kariya Matou, El-Melloi discusses with him about defeating Archer. He plans to have Berserker defeat Archer, Gilgamesh, during his discussion with Artoria and Iskandar at Einzbern Castle nearby. The group then interrupt the meeting between the three kings, and together with Berserker, they defeat Gigamesh. The effort however causes Kariya to pass out, which makes Berserker go out of control and attacks Artoria. Not wanting to lose Artoria and having no more use for Berserker with Gilgamesh gone, the group fight him. However, before they can finish him off, Berserker is defended by Iskandar. He explains that he is joining forces with Berserker to fight El-Melloi out of sheer dislike for him. Iskandar further explains that he finds him to strange for his nature as a Pseudo-Servant and his entirely accurate predictions. He continues that El-Melloi is an outside who trying to interrupt the war, which makes him a greater threat than a mere enemy. He then tells Diarmuid and Artoria that they'll be considered if they ally with El-Melloi. Diarmuid prepares to fight Iskandar on Ritsuka's order, but El-Melloi warns they're only allowed to defeat four Servants. Iskandar then leaves, taking Kariya and Berserker with him, vowing to fight the group once Berserker has recovered.

After Iskandar leaves, the group are confronted by Assassin, who has again come to kill Irisviel. El-Melloi tells him that despite their differing methodology, their goals to end the war are the same. He continues that Irisviel is merely a proxy Master for Artoria while serving as the Lesser Grail, but she denies with his claims of being a proxy. El-Melloi however believes that Artoria's true Master is Kiritsugu, but Artroia says she is contracted to Irisviel. Irisviel then shows her Command Spells to convince him of her status as a Master to his shock. The group then fight Assassin, and after he is defeated, El-Melloi reveals him to be a Counter Guardian. He further reveals that the activation of the Greater Grail will cause the end of the world, and says Fuyuki is the cause of the Singularity. He tells Irisviel that her being both the Lesser Grail and a Master are different from his records as that type of Master is meant to appear ten years later. El-Melloi further explains that her being such a unique Master with a powerful Servant means victory is certain for the Einzberns, which prompted the Counter Force to activate. This prompts Assassin to ask El-Melloi if the Counter Force in the war he knew, to which he answers it was fifty-fifty during the fourth and fifth war. Romani then calls the Singularity to be a "what if" where Einzberns are the superior faction in the fourth war. Agreeing with him, El-Melloi states Irisviel's Magic Circuits are likely what Chaldea read as a Holy Grail, even calling her a psuedo Holy Grail. Irisviel then asks him what meant by the world will end if the Grail is complete. He then asks Assassin if he wishes to stop the war without killing Irisviel, which Assassin agrees with.

Meanwhile, Iskandar captures Sakura Matou from the Matou Residence while burning the worms in the basement. He agrees to give her to Kariya in exchange for his right hand and Command Spells, which he concedes to. After serving his hand, Iskandar has Mithrenes take Kariya and Sakura to hospital outside of Fuyuki before leaving. After he leaves, Zouken Matou finds his manor to be burning and a contract-less Berserker. He then makes a contract make with Berserker to get revenge.

At the Greater Grail's cavern, El-Melloi has reveal the grail's corruption and his plan to dismantle it safely to Irisviel and Assassin. He changes the plan though to having the group destroy the Grail directly since they failed to win over Iskandar. Suddenly, he and Assassin detect Hassan's presence. After they defeat Hassan, the group move on to the the main chamber, where they're soon confronted by Iskandar. He explains that he has come to defeat El-Melloi, seeing him as a worthy opponent, and fights the group. However, after Iskandar is defeated, El-Melloi is severely wounded by Berserker on Zouken's orders. Zouken then explains to Irisviel that wants to witness the Grail's activation despite her telling him that the Grail is a failure. Wanting to defend the Grail, he commands Berserker to attack the group. However, with Berserker's defeat, the Grail is ready to be activated, and Zouken then extracts Magical Energy from Irisviel to hasten its awakening. Suddenly someone resembling Irisviel emerges from the Grail designated Black Iri. After devouring Zouken, she goes to devour the rest, saying five Heroic Spirits aren't enough to fill her. Diarmuid and Artoria decide to hold her off while the others escape. Irisviel is concerned for Artoria though, but she tells her that as the Master is safe, they can withdraw instantly via Command Spell. After she tells her and Ritsuka to be safe, Diarmuid implores Assassin and Mash to protect Ritsuka.

Outside of the main chamber, El-Melloi uses his remaining strength to make Waver Zhuge Liang's new temporary vessel. The group then return to the main chamber to assist Diarmuid and Artoria in fighting Black Iri. After she is destroyed, Diarmuid and Artoria say their goodbyes before disappearing since the Grail was destroyed. Afterwards, El-Melloi accounces that the Grail detected by Chaldea is gone, and asks Irisviel what she'll do now since she can't become the Grail any more. Irisviel agrees she is unsure, but Mash asks her to return with them to Chaldea since their original goal was to retrieve the Grail. She accepts the offer, and El-Melloi helps Waver leave the cavern. Assassin and Irisviel then talk with each other of their strange yet pleasant connection. He tells her that he is satisfied he was only to protect something without sacrifice. After they thank each other, Irisviel rayshifts back to Chaldea with the others. Later, inside the Grail chamber, Assassin tells Angra Mainyu to come out of the Grail already. After he is emerges, Angra Mainyu asks why Assassin didn't warn the group of him since they only destroyed the vessel and not him, the contents. Assassin answers he didn't want to rely on others from another world to destroy him, whose curse solely belongs to his own world. Angra Mainyu criticizes him for continuing to be a Hero of Justice even after death. But, Assassin has no regrets for his chosen path, saying they'll both curse and save the world respectively. Before fighting him, Angra MAainyu asks him for his name, to which he answers his name is Kiritsugu Emiya.

Rashoumon: The Devilish Capital of Restless Spirits and Drunken Dreams
Rashoumon: The Devilish Capital of Restless Spirits and Drunken Dreams (鬼哭酔夢魔京 羅生門) refers to an event which occurred during the Human Order Incineration Incident. It involved a distortion which would have become a Singularity if left unchecked, located in, during the.

Setting
After Shuten-douji and Ibaraki-douji woke up in the distortion, they found the Holy Grail in front of them filled with wine. After they drank it, the wine soon vaporized and spread throughout Kyoto causing its citizens to become drunk. Meanwhile, the wine grants the wishes of Shuten and Ibaraki's heart, but their wishes are twisted by it. Shuten wished to have fun with Sakata Kintoki again, causing him to be summoned into the distortion. Ibaraki wished to go on a rampage with Shuten, but it was twisted into going on a rampage with her power. As a result of the wish, Shuten's power was absorbed into Ibaraki, eventually causing her to become unconscious. Then, in a panic, Ibaraki captures her and shut herself behind a large gate in Kyoto

History
Ritsuka Fujimaru and Mash Kyrielight rayshift in Japan, gazing upon the cherry blossoms scattering in the wind. They soon take notice of strange aroma, which Romani Archaman believes they should gather information on. In the meantime though, he notifies the pair that they're possibly in the Heian Era, but he isn't exact on their coordinates. Sakata Kintoki then suddenly emerges from a pile of petals that Mash noticed earlier. Kintoki tell her and Ritsuka to come with someplace in the mountain, but they're ambushed by monsters. After killing them, Kintoki reveals that they're in Kyoto, and Romani tells them the aroma they smelled earlier was wine. He then directs the group to the source of abnormality, and figures that Kintoki was forcibly summoned into the distortion.

Joined by Kintoki, the group travel through a residential district on their way to the abnormality's source. However, Mash begins to act overprotective of Ritsuka from her getting drunk from the alcohol filled mist. After defeating some drunken citizens, the group move forward, but they notice how empty Kytoto is beyond the corpses lying in the street. They soon arrive at a large gate, where Kintoki realizes that the mist and chaos in Kyoto are thanks to an Oni. Suddenly Ibaraki-douji appears before the group, surprised to see Kintoki. She then shows an unconscious Shuten-douji, who she says will become her sacrifice. He tries to warn her that Shuten-douji will devour her from the inside if she were to eat her. Ibaraki-douji responds by summoning the Great Grudge of Rashoumon and attacking the group. However, neither her nor Kintoki can overcome each other, so she retreats beyond the gate. Left fatigued by the fight, the group go to find something to eat before trying again tomorrow.

After another failed attempt to defeat Ibaraki-douji, the group retreat to the field they first arrived in and report their progress to Romani. Asked by him, Ritsuka reveals that Mash is still drunk from before, though she doesn't seem affected during battle. Romani states the alcohol in the air will not disappear until the source is destroyed, then he tells the group a plan he thought up. The next day, after fighting Ibarki-douji again, Mash tells Ritsuka and Kintoki that they may not have necessarily need to defeat her to solve the distortion. She explains that they need to destroy the source of her beyond the gate first before dealing with Ibaraki-douji. Mash then contemplates how to get pass the gate since climbing over it is the out of the question due to thick and sinister fog-like thing above the gate and wall. Though she doesn't know what it is, she feels it is bad and there's no way what it happen to a Servant if they touched. As suggested by Ritsuka, the group try to look for any detours that can get them past the gate. Searching for a detour, the group find an enormous cliff on the west end of Kyoto. Kintoki says that Japan and its islands has either sunken and its topography is different from the regular Japan. Mash agrees with him and notices a island in the distant, but it will be impossible to get to without a boat. Unable to find a detour, the group realize that they have no chose but to continue fighting Ibaraki-douji.

After yet another failed attempt to defeat Ibaraki, Kintoki states how she escaped being killed by after her arm was chopped off by his sword, Higekiri. Mash wonders if she possesses the Disengage Skill based on what he said. She then asks him if he knew Ibaraki during his lifetime. Kintoki answers he only knew of her battle habits, but he hesitates to answer when asked about Shuten. He says Ibaraki was the boss of all oni on and Shuten was merely a freeloader living there. Yet despite that, Shuten was treated by Ibaraki as her superior, saying Shuten had something she lacked. Unfortunately, despite the two being equal in power, Ibaraki's declaration caused problems among the oni. Kintoki then describes Shuten as a wicked coward yet she was good to those she shared a bond with. Mash asks him why Shuten was unconscious, to which he replied that Ibaraki must have gotten impatient with her. He asserts that onis will always be demonic and he will always hunt them before heading out.

After the group fights her again, Ibaraki is left in a near-defeated state yet refuses to give up and unleashes her Noble Phantasm against them. After she escapes when her attack is blocked, Kintoki reveals that Ibaraki only unleashes her Noble Phantasm to give herself cover to escape. He then describes her as furious on the outside yet submissive on the inside while Shuten is the opposite. With Ibaraki near defeat, the group go to prepare for the decisive battle. The next day, Ibaraki is finally defeated by Kintoki's Golden Spark. She questions how the group was able to defeat her as she stands above all oni, saying human shouldn't be able to slay her even if they're Heroic Spirits. Kintoki rebukes her for her attitude, calling her a child without guts. Ritsuka points out that she never ate Shuten, and Ibaraki responds she only threaten to eat her in an hypothetical sense. She tells the group that she would never consider hurting her of respect and more importantly, fear. Ibaraki then threatens to curse Ritsuka after learning their name, but her threats are ineffective since the group do not fear. Kintoki realizes the reason why she captured Shuten and gave alcohol to the humans was because there was too much alcohol for her to handle

After Ibaraki retreats, Shuten finally wakes up, the group go to fight her. However, she stops Kintoki's axe at the last second, and he asks her how she was captured by Ibaraki despite being stronger. Shuten realizes that most of her power was absorbed by Ibaraki, which shouldn't be possible. After teasing Kintoki, she takes the group to the source of the abnormality, which turns out to be the Holy Grail. Shuten explains she woke up in Ibaraki with the Grail in front of them filled with wine. She continues that after drinking the wine herself, she pressured Ibaraki into drinking it as well. However, she eventually asleep after drinking too much and her power was absorbed by Ibaraki. Shuten then states the wine grants wishes, which Romani speculates comes from the Grail. She further explains the wine actually grants the wish of the heart though it twists it first. The wine soon vaporized and spread throughout Kyoto causing its citizens to become drunk from the mist. Shuten reveals Ibaraki's wish was to go on a rampage with her, but it was twisted into going on a rampage with her power. After the Grail is destroyed, Shuten offers to have a drink with Kintoki before disappearing. Mash realizes Kintoki was summoned into the distortion because Shuten wished to have fun with him again. However, she becomes worried about who placed the Grail in front of the oni and filled it with wine. Kintoki responds that something else will happen if the mastermind is still around before disappearing. Afterwards, Mash offers to have a drink with Ritsuka when they return to Chaldea, but Romani scolds her that they can't drink until they're of legal age.

Onigashima: The Great Tale of Demons
Onigashima: The Great Tale of Demons refers to an event which occurred during the Human Order Incineration Incident. It involved a distortion which would have become a Singularity if left unchecked, located in the fictional island of ,

Setting
Occurring in the same distortion of Rashoumon, it was constructed by Minamoto-no-Raikou when she turned into her oni self, Ushi Gozen, as a result of absorbing too much divine energy. After creating the distortion with the Authority inherited from her ancestor, Gozu Tennou, Ushi decided to construct a place where Sakata Kintoki can be safe from the scorn of the human world. She then drew the island Onigashima into existence and created its oni residences in the same matter. These oni were the same as the ones she drew for Kintoki during his childhood. Not all the oni were drawn well though with the better ones being called Onimaru and the others being compared to scribbles. While the Onimaru served as gatekeepers, the lesser oni were used to further the island's construction along with humans they enslaved.

History
Arriving in the distortion, Ritsuka Fujimaru and Mash Kyrielight are told by Romani Archaman that they arrived on the island they saw in Kyoto. Unfamiliar with Japan's landscape, Mash asks Ushiwakamaru, who came with the pair, for her assessment. She is shocked to see the shape of the island when the group are suddenly attacked by an Oni. After killing it, they realize the island they're currently on is Onigashima, the legendary island of the Oni. Romani tells them he is unable to pinpoint the temporal coordinates of the island, which was similar case during Kyoto. Ushiwakamaru says the island didn't exist during her brother's life, and Romani speculates it was created as the abnormality. He then asks the group to investigate who created Onigashima, and tells them the Singularity response is located at the island's highest, most remote part: a steep, rocky mountain. Soon after running off with Cath Palug though, Ushiwakamaru reports back to Ritsuka that she found a Servant lying unconscious on the beach. The group defeat the oni surrounding him, and the Servant regains consciousness and asks for their identities. Getting up from the ground, he dispatches an oni with a kunai, and states his name is Fuuma Kotarou. Helping the group kill more oni, he and the others soon find themselves surrounded. Kotarou tells Ritsuka his Noble Phantasm summons the spirits of the Fuuma clan, which he'll use to create a diversion on Ritsuka's order. However, Ushiwakamaru says even with a diversion, she and the others don't have the firepower to break through the enemy horde. Suddenly though, Sakata Kintoki arrives before the group on a motorcycle after jumping from a nearby cliff. He then helps them defeat the remainder of the oni horde.

Moving on to a mountain pass, Romani asks Kotarou why the oni were attacking him. He answers that he was summoned on the island rather recently, and speculates he was summoned due to his connection with oni. He further explain his connection comes from his clan's secret technique of turining into an oni, which became a currently sealed Noble Phantasm. Kotarou then goes to say that he planned to observe and study the oni's behaviors in the hopes of unleashing his Noble Phantasm. However, he was overwhelmed as the oni kept calling more and more oni. Romani then asks Kotarou and Kintoki to help them solve the mystery behind the island. They both agree when Kotarou senses an oni scouting party. After the oni are killed, the rest of the group check the area while Kotarou and Kintoki go on recon. Looking out from a cliff, Mash and Ushiwakamaru spot a forced labor camp filled with humans run by oni. Kotarou returns from recon and reports there are more forced labor camps. He calls liberating every camp unrealistic, so he suggests doing something about the mastermind. Kotarou continues he found a way to the island's highest point, but said path requires going through three gates that are always closed. Opening the gates requires retrieving keys from three great oni that serve as the gate keepers. Kotarou also states there are ones commanding the lesser oni and that they hired a terrifying guard. After killing more oni, the group are worried Kintoki hasn't returned yet. Suddenly Romani and Kotarou detect something approaching, so the group hide and observe. They see that oni, higher-ranked than the earlier ones, coming from the forced labor camp. Given their ability to talk, Mash wonders if they can get information from them, but Ushiwakamaru runs off towards the oni. However, the group spot a Servant killing the oni and go to help her.

After defeating the oni, Mash is concerned the oni weren't particularly strong. Romani states they are only spiritual bodies on the inside, and asks Ushiwakamaru for further input on Japan's phantasmals. She states such being are not so different than those from the west, mostly categorized as spiritual beasts or spirits of the dead. The former are physical existences hidden from the human world while the latter are born into world as a living curse without physical form. Ushiwakamaru says oni are of the latter catergory that are born of a cursed created by human deeds. Afterwards, Ritsuka tries to ask for the female Servant's identity. She answers she is merely a warrior passing by and gives her thanks for the group's help. She then asks why they have come to the island, but she becomes distracted by Ushiwakamaru. She gives her name and admiration for the female Servant's skills. The female Servant says their paths just happened to cross and will be glad if they cross again. After she leaves, the group talk about her strange aura, one that Ushiwakamaru finds nostalgic. Kinroki then returns and is told of the female Servant that slaughtered the oni. He ponders her identity based on the other's descriptions, and he is told how they need to get to the mountain's peak. Kintoki then reports he found a place similar to a human settlement, which Romani believes would be a source of information.

Continuing on the pass, Ushiwakamaru compares herself, Kotarou, and Kintoki to 's animal companions. After that matter is settled, the group arrive at the first gate. There they encounter Sasaki Kojirou, who is the hired guard Kotarou reported about. Sasaki states he was given the role of a pheasant-terminator with the mission to slay the evil bird that shoots beams from its beak. He asks where the pheasant is and Ushiwakamaru points to Kotarou. However, Sasaki is angered by this response, saying he came seeking a swallow equal to the one he fought when he perfected his technique. Even more frustrated, he states the group could have brought a Heroic Spirit who was falconer, one who turned into a bird in legend, or has some connection to birds. Kotarou apologizes and gives his name, which surprises and satisfies Sasaki as he'll face the leader of the Fuuma. He offer his friendship, but Kotarou rejects it absolutely. When Sasaski asks him, he tells of the three things he cannot forgive. One is people who lag behind weapon maintenance, two is subordinates who chase away the deliveryman. Three is people who rank the Fuuma lower than the Iga and Kouga clans. Due to Sasaki committing the third one, Kotarou prepare to fight him. Sasaski accepts the challenge and gives him advice as an apology before fighting. He states the first great oni is named Kazakoemaru, who is heralded as the embodiment of speed. After the group defeat both Sasaki and Kazekoemaru, they use the oni's key to open the first gate.

Continuing past the gate, the group find themselves in the settlement where the oni's human slaves reside. Romani tells them they're ill equipped to free the slaves, so eliminating the source of the problem would be the best course of action. Agreeing with him, Kotarou says merely freeing the humans would result in the oni capturing them again. After Romani tells the group to gather info before the oni arrive, they suddenly encounter Musashibou Benkei. Accepting a challenge from Kintoki, he tells the group there is another settlement higher up. Benkei continues he was actually looking for the group when he ended up in the village they're currently in. He decides to join them in slaying oni when an oni patrol appears. After defeating the oni, the group observe how people's wills have been broken by the oni's oppression. Leaving the village and joined by Benkei, they eventually encounter a checkpoint. Ushiwakamaru asks Benkei how he got pass the checkpoint, but he reveals he fell off the cliff and arrived in the previous settlement. Mash then states how the cliffs are far too steep to climb even for a Heroic Spirit, and worse they would be spotted by oni. Seeing the path is too narrow and steep to go around the checkpoint, the group decide to breakthrough. Kotarou says he and the others will distract the lookout and then sneak into the checkpoint. They'll cause a commotion inside to cause confusion, and at the right moment, Kintoki will charge in. Then, executing his plan, Kotarou dons an oni disguise and has the others pretend they're human slaves he's bringing in. Bringing them to the checkpoint, Kotarou tells an oni there that they were requested by the great oni. However when observing the group, the oni notices Ushiwakamaru's small frame and shamelessly, and doubts she can do any work. However, Benkei tells the oni that she is a seductress, then he knocks her out to "elimate" her as a threat to the oni. Benkei then drags Ushiwakamaru's unconscious body past the confused oni guard. Once inside Kotarou sends a signal to Kintoki, and after he arrives, the oni are sent into complete disarray. Defeating the oni, the group get past the checkpoint while Ushiwakamaru ponders why Benkei is so powerful on the island.

Continuing on the pass, Ushiwakamaru asks Ritsuka if Benkei was so strong before coming to the island. Benkei suggests they gather information at a tea house in the settlement up ahead that he visited before. However, Ushiwakamaru gets drunk from the tea Benkei offered, and takes a jizo statue she mistakes as one of her brother. She then fights oni to offer their heads to the statue, and the others go to help her. Unfortunately the statue's head falls off and Ushiwakamaru, after killing the last oni, chases it into a cesspit. After the head falls in, she abandons the body since, according to her, her brother would never go to the toilet. Afterwards, the group arrive at the second gate and there they encounter Tamamo-no-Mae. She begins to complain about not being in the role of the dog since they're on Onigashima from the tale of Momotarou. Pointing her ears out, Tamamo challenges anyone who thinks they're more suitable to play the dog than her. However, she reveals she merely got herself drunk from wine at a tea house and decided to stand in the group's way. Tamamo then introduces the second great oni, Wazahamimaru, who is called the embodiment of technique, before fighting the group. After they're defeated, the group unlock and pass the second gate.

Arriving in the settlement where the teahouse Benkei told them of is, the group encounter Shuten-douji and Ibaraki-douji. Both of the oni girls are seen working at the teahouse, inviting and welcoming customers of both human and oni alike. Eventually they notice the group. Shuten is glad to Ritsuka, Mash, and Kintoki while Ibaraki is not. After Romani explains their previous encounter with the oni girls to Kotarou, Kintoki accuses Shuten and Ibaraki of constructing Onigashima. Shuten denies their involvement with the island's construction though, and further reveals they decided to destroy it out of anger towards its construction. However, she decided to hold a banquet after drink wine that tasted familiar when poured into odd cup she found in the island's treasure room. Shuten also reveals a spell had been cast on all oni and humans from their current location down. She further reveals the cup to be the same kind of Holy Grail back in Rashomon though less powerful. The Grail isn't strong enough to produce the alcoholic mist but its effects will be felt when its wine is drunk. Shuten then suggests the group and she and Ibaraki join forces to find the mastermind behind Rashomon and Onigashima, which are both connected to each other. However, the group end up fighting the oni girls when Shuten decides to kill them after Kintoki refuses their offer. During the fight, Ushiwakamaru is left fatigued by her fight with Ibaraki, who goes to unleash her Noble Phantasm. However, Benkei uses his body to block it, and Ushiwakamaru disperses the flames with Kikenjō - Icicle Cutting after jumping from his shoulders. Eventually as Ibaraki struggles against the group, Shuten offers her the Grail's wine, which will grant her the power she had in Rashomon. However, the female Servant the group met before appears, and Kintoki reveals her to be Minamoto-no-Raikou. After she makes Shuten and Ibaraki retreat, Raikou decides to go after them while the group continue their journey up the mountain.

Arriving at the third and final gate, the group encounter Kiyohime there. She then calls forth Gorikimaru, who is called the embodiment of strength, and fights them. After they're defeated, the group unlock and pass the final gate. At the summit, they find Raikou standing before the Grail. Kintoki warnsthe others about getting closer to her however, and recognizes her to be not Raikou. He reveals her to Ushi Gozen, Raikou's oni self that she had sealed away herself. Ushi reveals she had acquired the Grail and constructed Onigashima using the Authority inherited from Gozu Tennou to create a kingdom for oni. She continues that Raikou decided to construct the island out of a bizarre kindness for those scorned by human society due to their strange appearance. Ushiwakamaru recalls Raikou had slain all oni on the island but, Ushi states she hates oni and slays then on sight like Raikou despite them being her workforce. She further reveals she created the oni by drawing them, and states she'll destroy all the oni on the island once its complete. Revealing she mortally wounded Shuten and slew Ibaraki a moment ago, Ushi tries to convince Kintoki to join her as she constructed the island for him. She also reveals that she is responsible for the Rashoumon incident to make everyone kill each other by getting them intoxicated with the Grail's wine. Kintoki refuses to join her and goes to fight her with the others. The group struggle against Ushi's immense strength though. She prepares to finish them all off when Shuten appears and ambushes her, but she is slain by Ushi afterwards. Using the opening made by Shuten, Kintoki eventually defeats Ushi with Golden Spark. He reveals though she jumped into lightning to knock herself out. Romani expresses concern about Raikou still being Ushi when she wakes up, but Kintoki says they can only wait and see. He further reveals that Ushi appears when Raikou builds up too much Divine Energy inside herself. Raikou then wakes up, having no recollection of being Ushi. Despite that though, she is able to recognize the incident as her fault and apologizes to the group for her behavior. After the others comfort her, Raikou apologizes directly to Ritsuka for the trouble she caused and hugs them as a token of forgiveness before disappearing. After Kotarou disappears due to his oni connection, the rest of the group return to Chaldea.

Prisma Causeway: A Magical Girl's Travelogue
Prisma Causeway: A Magical Girl's Travelogue refers to an event, part of a collaboration between Fate/Grand Order and Fate/kaleid liner PRISMA☆ILLYA 3rei!!, which occurred during the Human Order Incineration Incident. It involved a Reality Marble where Magical Girls from different parallel worlds waged war against each other.

Setting
The first Magical Girl was a demon who was raised in the human world, deciding to save people despite her origins. She became best friends with a girl named Mila, but was forced to kill her when Mila became the first corrupt Magical Girl. Eventually, forgotten by humans and her fellow demons, she would eventually pass into legend as the First Lady, the first Magical Girl. After she died, her regret over killing Milla caused a Reality Marble to begin to manifest. However, the First Lady still wished to help people through the magic of Magical Girls, which attracted Echoes, the spirits of failed Magical Girls from various parallel worlds. Furthermore, their despair and their obsession to remain as Magical Girls became a flow of magical energy. Using this flow, the First Lady formed and sustained the Reality Marble, and gave the Echoes temporary bodies and magical energy. Instigated by the First Lady, the Magical Girls killed each other as they each tried to establish their own kingdoms based on their differing ideals. Only a few survived this war to prove strong enough to create their own the kingdoms, and were each given a jewel that granted them absolute authority in their respective kingdoms. The survivors included: Medb, Nursery Rhyme, Medea Lily, and Helena Blavatsky, each of whom founded their own kingdoms. Medb founded the Land of Snow and Honey, becoming the strongest Magical Girl. Nursery Rhyme founded the Land of Sweets, where she became playmates with the Demon God Glasya Labolas after tiring of her candy citizens. Medea founded the Land of Dragons and Sea, where she isolated herself due to her despair of killing other Magical Girls. Helena founded the Land of Dead Bookshelves, serving as the gravekeeper for the Echoes. Eventually, Medb became the First Lady's servant and is made to gather more Magical Girls for her plan. However, none of them are found to be satisfactory, so the First Lady searches for a real Magical Girl.

Meanwhile, Mila existing in the Reality Marble as an Echo, opens a leyline to the outside, and summons Chloe von Einzbern in an effort to help her friend. Chloe witnessed the battles between Magical Girls while hiding her presence from them. Unfortunately, this act eventually causes her to be drained of magical energy to point of disappearing. It is that point when she met the First Lady through a familar, and becomes her vessel. The First Lady found a way to peer into parallel worlds in her search for a real Magical Girl, and eventually discovered Miyu Edelfelt to be perfect for her plan. She then confronted Miyu and Illyasviel von Einzbern as they were travelling to the Mirror World, and summoned them into the Reality Marble. Seperated from Illya, Miyu is imprisoned in the First Lady's castle, where she is restrained and tortured by the Anti-Magical Girl Mystic Code, Voile de Deuil. Meanwhile, Medb decided to rebel against the First Lady, and began to build her army of Magical Girls. Then, using her magical energy greater than the First Lady at the time, she opened a leyline to Chaldea, and inadvertently summoned Mash Kyrielight and Ritsuka Fujimaru as the latter's familiar into the Reality Marble.

History
Ritsuka Fujimaru and Mash Kyrielight awaken to find themselves in an unknown location. The pair decide to explore when they hear something screaming, which soon bumps into Mash. After apologizing for bumping into her, the strange object senses powerful magical energy from Mash. Seeing Ritsuka and Mash are outsiders, it asks for their help, and introduces itself as Magical Ruby when Ritsuka wonders what it is. Suddenly, the trio are attacked by barrage of spells from the air by Medb. Ruby reconginze her as the one who defeated its master earlier, and Ritsuka and Mash find her different from her usual self. Medb then introduce himself as the Magical Girl of Honey and Geis, Connacht★Medb, the queen who rules the Land of Snow and Honey. She then demands Ritsuka and Mash to immediately hand over Ruby to her as she summons monsters. Ruby refuses to let Medb be its master, prompting Ritsuka and Mash to fight the monsters. After her monsters are slain, Medb realizes her summoned monsters aren't at full strength in the neutral zone, their current location. Mash tries to stop her from summoning more monsters, but her attack proves to be too weak for some reason. As Mash's attacks are continuously blocked by Mebdb, Ritsuka tells her to retreat, but she refuses to give up. A tired girl then appears, who Ruby recognizes as its master. Surprised the girl survived being hit by her chariot, Medb asks for her name, inviting her into her army. The girl introduces herself as Illyasviel von Einzbern, and refuses Medb's invite instead demanding for her to gave her friend, Miyu Edelfelt back. Illya, with Ruby, then transforms herself into a Magical Girl. Infuriated, Medb prepares to kill Illya, but she is easily overwhelmed by Illya. Illya's next attack meant to finish Medb off is blocked though by Mini Cú with his own body. Mini Cú reprimands Medb for being unprepared to fight in someone else's territory, and has her retreat. After they leave, Illya's transformation suddenly wears off due to the Magical Energy feed from Ruby not stabilizing for some reason. Illya then introduces to Ritsuka and Mash, and relays her current circumstances to them. While traveling from her world to the "Mirror World", Illya and her friends encountered an unknown force that placed them in her current location. Immediately following that, Miyu was kidnapped by a magical creature, and Illya was quickly attacked by Medb, proclaiming herself a Magical Girl, afterwards. Ruby tells Mash it had scanned her when it bumped into her, stating her installed class of Shielder is very rare. Illya realizes that since she can't install the class card then neither can Miyu. Mash calls the spell to let a Heroic Spirit temporarily into one's body is unusual, stating Pseudo-Servants are similar exceptions only used during the Grand Order. She believes Miyu's kidnapping is connected to her and Illya sharing the same Magecraft. When Ruby calls her a Magical Girl, Ritsuka and Mash are suddenly contacted by Romani Archaman, and reveals they're inside someone's Reality Marble. .

Learning they're in a Reality Marble, Ritsuka asks Romani if he can get them back to Chaldea, which he says is fine along as Mash is with them. Mash asks if he can give Illya temporarily refuge in Chaldea, but Romani refuses as only her, Ritsuka, and Ritsuka's Servants can rayshift back. He continues they can't intervene too much with other eras, but Mash reveals Illya is from a parallel world. She states there'd no interference with an era since events arre inside a reality marble, and asks if Leonardo da Vinci can help. Illya interrupts her, saying she has to save Miyu, and thus cannot refuge in Chaldea. Da Vinci contacts the group, and theorizes the Reality Marble is preventing Mash from using her full strength as she doesn't fully meet its conditions. Romani orders Ritsuka and Mash to return to Chaldea, but Mash decides to stay behind to protect Illya. Upon returning to Chaldea, Ritsuka is shown a video by Romani that was recorded by they and Mash suddenly rayshifted into the Reality Marble. The video shows Ritsuka taking a nap in the command room, with Mash trying to wake them up. It also shows Mash suddenly shifting back and forth between her regular and Servant form. Romani then tells them to go to da Vinci's lab as she has something she wants to give them. After picking up the aforementioned item from da Vinci, Ritsuka returns to the Reality Marble. Upon returning however, they find Mash and Illya to be missing. Ruby tells Ritsuka that the girls were abducted by the residents of the Land of Sweets. Meanwhile, in the Land of Sweets, Mash and Illya are begged by its residents to stay with them forever. When Ritsuka and Ruby arrive, Mash explains she tried asking the people for information before being abducted by them. Mash then shift into her Servant form while Illya turns into her Magical Form, and they fight the candylanders. Afterwards, most of the candylanders flee upon learning Illya is Magical Girl, which she takes advantage to get information from a candylander. Learning the Queen of the Land of Sweets may know more, the group decided to head for her Candy Castle.

While heading towards the castle, the group are confronted by what appears to be Tamamo Cat. However after defeating her, they discover her to be in truth a Mystic Code copying Tamamo's form before breaking under the strain. Arriving in Candy Castle, the group are greeted by the Queen of the Land of Sweets, Nursery Rhyme. Romani confirms that she isn't the owner of the Reality Marble. Illya asks Nursery Rhyme if she or any of the people of her kingdom may know anything about Miyu. Nursery Rhyme promises to tell what she knows in exchange for playing with her. Illya tells her that they can play later, but Nursery Rhyme refuses as her only playmate is a black sheep. However upon summoning it, her black sheep turns out to be the Demon God Glasya Labolas. Before fighting the group, she reveals the people of the Land of Sweets were her previous playmate but they broke too easily, and that they were previously human. After she's defeated, Nursery Rhyme tells Illya to give up on finding Miyu upon hearing she's a Magical Girl. She explains the Reality Marble is a world where Magical Girls gather, who'll disappear when they stop playing as its the rule. She reveals herself to be one of the Magical Girls like Medb, who were able to create their own kingdoms. As thanks for playing with her and Glasya Labolas, Nursery Rhyme gives the group a jewel, which she says may help finding Miyu. After leaving the castle, Mash realizes her attack against Nursery Rhyme were more effective than against Medb, which Ruby attributes to her Magical Girl power increasing. Suddenly, the jewel begins to glow, and points the group in the direction of the Land of Dragons and Sea.

As the group sail through the ocean, Romani asks Illya how she plans to return to her original world. Illya doesn't hasn't have a clue though, so Romani asks Ruby. Ruby answers neither Illya and Miyu can use spells advanced to transfer between parallel worlds, lacking the skill and knowledge to precisely selection a location to return to. Romani states their world and Illya's world being connected magically is a dangerous situation. Suddenly, the group is beset by a swarm of wyverns. After slaying the wyverns, the group notices a galley charging towards their ship. After defeating the Dragon Tooth Warriors that boarded their ship, the group are greeted by Medea Lily who proclaims herself as the Magical Girl of Love and Healing, Medical★Medea. Illya and Ruby recognizes her from their memories of fighting Medea in her world, for which Medea apologizes for despite having no memories. She decides to stand down, and asks the group which kingdom's Magical Girl did they kill to obtain their jewel. Illya explains the jewel was given to her by Nursery Rhyme without them trying to kill each other. Realizing they've come to take her jewel, Medea invites the group to her castle.

Inside her castle, Medea reveals she wasn't summoned instead she was wished to be. Moving onto the throne room, the group tell her of their current situation, which makes her decide not to turn them into pig as she originally intended. However, Medea warns Illya won't be leaving as she is a Magical Girl, believing she'll betray her as well. However, Jason convinces her to cease her sneak attack on Illya as he recognizes Illya as a good natured person. Medea then offers to never interfere with the group's affair in exchange for then never interfering with her kingdom. She also tells them she'll never hand over her jewel, which she calls the Tomoi Stone, as it supports her kingdom, and grants her power. Medea reveals the Reality Marble once had many Magical Girls, but they warred against each other, including herself, trying to establish their own kingdoms. As she continued fighting the other Magical Girls, her jewel grew in weight and shone brighter, which serves as the catalyst of her kingdom. She reveals the Neutral Zone is a buffer zone where a Magical Girl cannot receive the blessings of her power. Equating the loss of her jewel to her own death, Medea demands the group leave her kingdom, and tells Illya to use her jewel to create a kingdom filled with friends. Illya refuses to do so as she only wants to get Miyu back and return to her world with her. However, Medea reveals Magical Girls cannot leave the Reality Marble, and tells Illya she'll use the jewel's power in the end. She continues Illya should give up on Miyu, and reveals Nursery Rhyme disappeared after giving her jewel as they're what keep Magical Girls alive. Illya refuses to give up though, which makes Medea finally snap and fight the group. She refuses to be defeated though, and prepares to transform into her adult self to Mini Jason's dismay. However, Illya stops her though, saying she'll finding a way to save Miyu without Medea's jewel. She also believes Medea created her kingdom to fight for something she holds dear to her. But Jason reveals Medea created her kingdom due to being indebted to him, and she's been protecting her jewel out of fear of other Magical Girls. He continues she isolates herself in her kingdom to stop herself from becoming a witch, though Medea says he told her to do so. Jason replies that she'll become a witch if she leaves her kingdom, and she'll turn into an Echo if she becomes a witch. He then gives Medea's jewel to Illya, not wanting Medea to become a witch. Medea accepts the outcome, but remains silent on the subjects of Magical Girls fight as it'll only bring back sad memories. Returning to their ship, Mash tells Romani what occurred while Illya contemplates with Ruby what Medea said to her. Illya realizes the Reality Marble is only cute on the surface, saying they need to find its owner to at least find a clue as to Miyu's whereabouts.

Following the light of the jewels, the group arrive in the Land of Dead Bookshelves. Mash notices a large black wall that Romani says prevents him from reading anything beyond it to his concern. Suddenly a ghost suddenly appears before them, but they decide not to fight it since it's alone and seems passive. After the ghost departs for the black wall, the group continue onto the center of the ruinous land. Concerned the jewels' light stopped leading them, Illya decides to transform and get an overview look of the area. While that happens, Ritsuka tells Mash out the video Romani showed them. Suddenly, hordes of ghosts come through the walls of the buildings. Seeing they're now aggressive, Mash transforms into a Servant form, and helps Illya fight them off. Unfortunately, the ghosts prove too numerous and strong for the two girls. Helena Blavatsky then comes out of a building, curious that a Magical Girl would come to a land drained of its Magical Energy. Illya asks if she is the Land of Dead Bookshelves's magical girl, to which Helena responds she is one of them. Apologizing for the ghosts' behavior, Helena reveals the land to be the graveyard of Magical Girls, and the ghosts to be those of Magical Girls. Recognizing Romani's communications as a leyline directly linked to a parallel world, Helena realizes "she" found a way to the outside world. She tells the group to come to her library so she may continue talking without danger.

Inside the library, the group is introduced to Helena's partner, Mini Edison who hasn't talked for a long time. Romani tells Ritsuka and Mash every book in the library is a grimoire, which Helena reveals them to be once Magical Girls. The ghosts of Magical Girls are called Echoes, who normally sleep as grimoires. However, Helena is unsure why the Echoes outside attacked the group, and they don't attack her as her role is to serve guests symbolized by her jewel. When Ritsuka asks if she is the Reality Marble's owner, Helena reveals it was created by a Magical Girl named First Lady as told to her by the Echoes. She continues First Lady is in the center of the world beyond the black wall, which cannot be destroyed nor perceived beyond by any magic. Curious why Illya is so fixated on Medb, Helena hears from her that Medb kidnapped Miyu. She wonders if First Lady had an effect of Medb who was previously only interested in the jewels. When Romani asks of her knowledge of parallel worlds, she reveals the Magical Girls in this world were once girls from parallel worlds, who couldn't become Magical Girls anymore in their own. Thus, the girls traveled to the Reality World to continue being Magical Girls. Mash then asks if she was summoned into the world as a Magical Girl, which Helena states to be fact as Ritsuka serves as Mash's familiar. She then gives her jewel to the group, unconcerned the Echoes will attack her without it. She tells Illya that wasn't Medb who kidnapped Miyu, but instead the First Lady was the culprit, who disguised herself as one of Medb's familiar. Illya thanks Helena for the information, but she still refuses to take the jewel. However, Helena reveals all of the jewels are needed to bypass the black wall to reach the First Lady as they're the crystallized emotions that grant wishes. She warns though the First Lady is likely gathering the jewels to use them to escape to the outside world. Realizing the First Lady made the Magical Girls fight each other to get their jewels, Illya vows to stop her. Helena warns however that task is impossible as the First Lady's power in the Reality Marble is absolute. Illya however refuses to let Helena give up though, which causes the grimoires to shake from frustration of being unable to escape their fate. Helena demands Illya to take her jewel under threat of death, so she can finally disappear. However, Illya responds by transforming into her Magical Girl form, and fights Helena who believes Illya's wish to save her and Miyu to be hollow fantasy. After she's defeated, Helena accepts Ritsuka's offer to join their group.

Returning to the Neutral Zone, Mash is asked by Illya to return to the Land of Sweets to check on Nursery Rhyme. Helena states how Medb became the strongest Magical Girl since belief in onself is the source of a Magical Girl's power. Because of that, Medb was able to maintain self unlike the other Magical Girls. Helena then speaks of a time she had traveled with Medb before the latter became obsessed with her lust for control. She also reveals Medb is forming a rebellion against the First Lady when Illya mentions Medb wanting her in her army. Suddenly, Medb's monsters appear, and the group fight them. After defeating the monsters, Ritsuka and Mash are unable to contact Ritsuka, fearing they won't be unable to return to Chaldea. Fortunately, Romani reestablishes with them, but he reveals Chaldea was attacked by hostiles using its leyline connection. Servants already present at Chaldea were able to repel the assault albeit barely. Romani asks Ritsuka and Mash to immediately return to Chaldea, but knows they won't easily leave Illya alone. He decides to cut the connection with Ritsuka and Mash to prevent any effects from their side. He gives them five minutes to make a decision before contacting them again. Suddenly, it starts to snow, which Helena sees as sign of Medb attacking the surrounding lands. Ruby tells Mash to return to her regular form as her power is now solely dependent on Ritsuka's magical energy since the connect with Chaldea is cut. Ritsuka decides they need to pinpoint the cause of the assault on Chaldea, which Helena agrees with. After the group decide to stay to help Illya, Ruby has Illya teach Mash how to recharge her magical energy through kissing. Romani then reestablishes contact with them to hear Ritsuka and Mash's decision.

After hearing Ritsuka and Mash's decision to stay behind, Romani cuts the connection for the time being. The group then travel to a snowy field that was once the Land of Sweets, which was the result of becoming part of the Land of Snow and Honey as Mini Cu reveals. Ritsuka asks him if he and Medb were ones who sent the hostiles into Chaldea. Mini Cu realizes Medb no longer needs to steal the First Lady's power if that is the case. The group then fight monsters summoned by Mini Cu despite Mash being weakened in Medb's territory. After the group slays his monsters, Mini Cu prepares to unleash his Noble Phantasm, Gentle Bite Coinchenn on Illya despite knowing Medb wants her in her army. Mash protects Illya from the Noble Phantasm when Magical Sapphire suddenly appears. Ruby tells Sapphire to make a temporary contract with Mash, which Sapphire agrees since Mash is Illya's ally. After Sapphire contacts with Mash, Mini Cu retreats as Helena tells him to tell Medb Illya has two jewels, which he already knew. Sapphire then plays a message from Miyu revealing she is a prisoner in the First Lady's castle beyond the black wall. Miyu reveals the First Lady had lured Magical Girls into the Reality Marble, having found technology capable of interfering with parallel universes. Despite not knowing what the First Lady from her, Miyu knows she needs to be stopped. She warns though that Illya shouldn't go to the castle, saying to send someone else instead. The message then cuts as a patrolling familiar nears, and Miyu sends Sapphire to deliver the message. Observing that Miyu's transformation hasn't reverted despite her distance from Sapphire, Ruby realizes the First Lady has special powers over Magical Girls. Sapphire says Miyu may have realized something about the First Lady's true identity as to why she didn't want Illya to come. Helena also doesn't know the First Lady's true identity, only hearing that she is the first Magical Girl.

The group travel to Medb's castle to confront her, but Helena decides to stay behind as she doesn't want to see anymore Magical Girls fall. Ritsuka, Mash, and Illya then enter the castle after Helena gives her jewel to Illya. Inside the throne room, the group confront Medb who tells Mash to forget her world, and join her instead. Medb calls the group arrogant for believing they can save the world themselves, saying they'll never rule their own fate. She calls the other Magical Girls unworthy of her army, only wanting Illya to join her. Medb then fails to trick Illya into believing Ritsuka and Mash are secretly trying to take over her world. She decides to help Illya save Miyu in exchange for them joining her, saying they'll make Ritsuka and Mash into their slaves. Mini Cu tells her to kill the pair instead, but she decides not to listen to him. Medb then reveals she was the First Lady's servant to grant the First Lady's wish to leave this world, which lead to the demise of many Magical Girls. She decides to take Illya for herself before the First Lady, but Ritsuka realizes she is fighting against despair. Illya refuses to believe that however as Medb's attack on her and Miyu made it possible for Miyu to be kidnapped, and states Medb is also trying to invade Chaldea. Ritsuka says the First Lady is at fault not Medb, which greatly enrages the latter. Mini Cu launches his Noble Phantasm at Ritsuka, but it's blocked by Mash and Illya. Reinvigorated by Mini Cu, Medb fights the group. . After she is defeated, Mini Cu tells Medb that her sympathy is way she lost, though she denies it. However she does reveal she made her army for those Magical Girls who had no where left to go. This makes Illya realizes Medb considered the Magical Girls who disappeared as comrades, which makes Medb's heart to finally break. As a result her castle begins to collapse, and Ritsuka and Illya plead with Medb to come with them. However, Mini Cu tells them that's impossible as Medb can no longer bare the strain of forcibly interfering with parallel worlds. The group then escaping the collapsing castle, leaving Medb and Mini Cu to disappear together. Outside, Medb's jewel appears in Mash's hand, and Illya returns to Helena's jewel returns to her. With all four jewels, the group can now bypass the black wall and enter the First Lady's kingdom when the jewels suddenly glow brighter.

Returning to the Neutral Zone, the group watch as the black wall disappears. Illya, Ruby, and Sapphire fly up to get overview of the First Lady's kindgom. Sapphire realizes the castle changed with the black wall disappeared. Helena senses all of the world's magical energy is gathering to the First Lady's location, wondering if the First Lady found a vessel capable of containing that much magical energy. Romani then contacts the group, telling them they'll be given Chaldea's full support. Da Vinci calls the Reality Marble a dumping ground for failed Magical Girls, who she considers dangerous normally as they possess overwhelming magical energy able to use magecraft intuitively. However, the despair and obsession of those Magical Girls who failed became a flow of unformed magical energy. This flow of magical energy eventually became a stagnant pool, with the First Lady becoming its locus, and the Reality Marble forming mostly on its own. The group realize everything will return to normal if they defeat the First Lady when Illya warns them a large incoming group of the First Lady's familiar. . Though overwhelmed by the sheer number of familiars at first, the group are able to breakthrough and enter the First Lady's kingdom.

As the group head closer to the First Lady's castle, Helena notices the familiars shifting form, becoming stronger. Mash attributes this the First Lady reacting to their presence in order to prevent their approach. Ritsuka wonders if the First Lady is trying to hide something, to which Helena guesses it has something do with the jewels. Mash wonders if the First Lady deactivated the black wall instead of the jewels. She wonders further if the First Lady intentionally made the Magical Girls fight each other from her kingdom. Helena calls the First Lady's actions contradictory, though the group ascertain her motives until they confront her. Suddenly the group are ambushed by a large number of enemies, and Ritsuka tells Illya to go ahead. However, Illya decides to stay and hold the enemy while the others go to the castle, but Sapphires says she won't make to Miyu in that case. As the group fight the large enemy force, Helena destroy a number of them herself, and tells the others to go on ahead to the First Lady's castle. After the others leave, Helena laments that she forgot to tell them they need the jewels to return to their original world. Though she won't give them her jewel, she is confident they can return home if Illya and Miyu have two jewels. As Helena realizes the true power of the jewels, like Medb did accidentally, Mini Edison appears to fight with her.

Inside the castle, the group head to the First Lady's throne room where they see a girl on the throne. Illya recognizes her as Chloe von Einzbern, whose disappointed that Illya made it the throne room. Chloe reveals that she and Miyu have been in the world for a very long time, though she been in it since the beginning. The group find Miyu restrained by lace ribbons, which a part of transforms into hostile familiar when Mash tries to check her condition. Chloe calls it a defensive reaction of the Voile de Deuil, an Anti-Magical Girl Mystic Code. She reveals that she followed Illya and Miyu into the Mirror World unnoticed, which frustrated her to a degree. She ended jumping into the Reality Marble, but ended being trapped alone long before Illya and Miyu arrived. Chloe had witnessed the various Magical Girls fight each as she hide her presence from them, but her magical energy drained to the point of her disappearing. That was when she met the First Lady through her familiar. She also confesses she hoped Rin Tohsaka and Luviagelita Edelfelt would saver her, but they didn't notice her disappearance in the first place. However, Chloe calls her appearance in the Reality Marble an inevitability as the First Lady turned her against Illya by calling her an accessory to Illya. Illya tries to tell her that's untrue, but Chloe projects a weapon in response and fights Illya. However, Chloe's shared pain with Illya puts her at a disadvantage when she reveals herself to be the First Lady's vessel. Unsure if it was the First Lady's idea to abduct Miyu, Chloe's body is completely overtaken by the First Lady, who promised to wait until after Chloe's duel with Illya. As she introduces herself, the First Lady reveals she was born in the Demon World, but raised in the human world. Hiding her identity, she fought for the people, but she lost her homeland and was forgotten by humans and her fellows demons as a result. Yet despite that, she doesn't hate them as her only desire is to keeping granting girl's wishes. Her feelings of wanting to spread the Magical Girls's magic of love and hope throughout the world attracted Echoes to the Reality Marble. The First Lady reveals she is an Echo as well, having needed an invisible presence to form and sustain the Reality Marble. She gave the Echoes temporary bodies and magical energy to create their kingdoms, but they couldn't make her wish come true. She needed to a real Magical Girl to accomplish that, which is when she met Chloe and made her into her vessel. Using Miyu's power, the First Lady will give the Echoes new incarnations to spread them across parallel worlds as Magical Girls to save people and defeat real enemies. Not allowing interference in her plan, she reveals she'll soon absorb Miyu, and Chloe is still resisting assimilation with her. Even though she understand the First Lady's wish, Illya refuses to let Miyu and Chloe be sacrificed for the sake of that wish. First Lady believes the group's opposition to her wish is due to her being an Echo, thinking they'll forget her as well. Illya tells the First Lady that she's making an mistake, which Chloe had done before. Illya believes the First Lady's wish would eventually become a curse while saying she continued being a Magical Girl thanks to her friends. First Lady responds she had friends as well yet the world abandoned her. She believes Ritsuka will be forgotten once they've save the world, and Mash will hope to retain her bond with Ritsuka forever. Mash realizes the First Lady is pain as she fights against her destiny, which she respects. As the First Lady disbelieves Mash won't forget, Miyu asks Illya to help Chloe and the First Lady both. She says the First Lady's words are false as she hides an impossible wish deep in her heart. Chloe then briefly takes back control of her body to tell Illya do something before the First Lady takes control back. The First Lady reveals her and Chloe's desire for Miyu allowed her to break through the latter's mental wall and fully control her body. She continues that once Miyu is emotional broken by seeing the group's defeat before her, she'll use Miyu to reach infinite parallel worlds. Illya refuses the First Lady's words, and asks Ritsuka and Mash to fight with her. Mash realizes the other Magical Girls she met, while filled with despair, continued to persevere despite that. The group then fight the First Lady in order to save her from herself.

With the First Lady's defeat, Chloe slowly regains control of her body, and Miyu is freed from her restraints. Illya confesses to the First Lady that she had the task to save the world, she wouldn't know what to do. But she does know she wouldn't hesitate to use her magic if her friends and family were in danger to protect them even if it meant her despair. The First Lady is reminded of her old self, and confesses she chose to save the world over her best friend. Her friend refused to be Magical Girl, and became an enemy of the world, forcing the First Lady to kill her to protect the populace. As the First Lady laments she won't be able to apologize to her friend, Helena and Mini Edison appears. Helena has the group move the First Lady outside, where they encounter the Echo that was wandering around the black wall. Helena states she found her moving towards the castle when the black wall collapsed. Ruby has the Echo possess Illya, who proceeds to argue with the First Lady. The First Lady recognizes her as Mila, who became an Echo since she was a Magical Girl even if it was for a brief time. Mila reveals she was a Magical Girl and the First Lady's friend who was killed by her. Ruby realizes Mila is possibly the first corrupted Magical Girl, though Sapphire tells her to be quiet. Mila confesses to the First Lady that she chose her over the world as the people were causing her to despair with their greed and dissatisfaction. She reveals the Reality Marble to be the manifestation of the First Lady's regret, and confesses she wanted to go beyond the black wall in order to bring peace to her friend's heart. Helena realizes Mila was the one who opened a leyline to the outside world, and summoned Chloe to the Reality Marble as her wish. The First Lady reveals Medb was once stronger than her, and used her vast magical energy to open a leyline to Chaldea, making Mash to sleepwalk before her and Ritsuka's arrival in the Reality Marble. The First Lady then begins to disappear causing her Reality Marble to begin collapsing. Wishing to prevent that, Helena asks the First Lady to give ownership of the Reality Marble to her. She wants it to be a place where wounded Magical Girls can go, in order to stop more girls from becoming like the First Lady. The First Lady agrees to this, and gives ownership of the Reality Marble to Helena. Mila helps the First Lady to finally entrust the future to new Magical Girls before they disappear together. Using the power of the jewels, the group (except Helena) return to their respective worlds. However, upon returning to Chaldea, Ritsuka, Mash, and Romani find Chloe there now as one of Ritsuka's Servants.

Some time later, Ritsuka, Mash, and Chloe are suddenly summoned back into the Reality Marble. Blackbeard and the Phantom of the Opera then before the trio, wearing miniskirts on heir regular outfits. They state their love for Magical Girls to the point of wanting to be with them and become one. Unable to become Magical Girls in reality, they found a way into the Reality Marble, and formed the Magical Gentlemen with two other Servants. The group notice the Reality Marble has changed since the last time, with Chloe noticing the spatial connections and enemies being different. She also notices that Helena isn't around despite becoming the Reality Marble's new owner. Although considering Blackbeard and Phantom's desire to be with Magical Girls harmless, Chloe nonetheless attacks them for turning her first mission into a farce. She misses however, even with Caladbolg III, forcing the pair to retreat. The group decide they need to defeat the Magical Gentlemen.

Encountering the Phantom in the candy castle of the Land of Sweets, Mash begins to believe he is harmless. Chloe, however, asks him what he'd do with a bird that stopped singing, as the Phantom used songbirds as an analogy for girls earlier. After hearing his answer that he'd kill the bird if it didn't sing, the group fight and defeat the Phantom. Next, the group confront Blackbeard inside the castle of the Land of Dragons and Sea. Mash asks him if his plans involve bringing harm to the Magical Girls, to which he answers he wants somebody close yet just out of reach even he must take it forcibly. Tired of his perverse nature, the group fight and defeat Blackbeard after he declares the greatest Magical Girl of all is about to appear. Later, they encounter Gilles de Rais inside the library of the Land of Dead Bookshelves. The group questions his interest in Magical Girls instead of something more akin to him, such as saints and witches and the like. Gilles answers he considers Magical Girls to be miracles of God, even calling Jeanne d'Arc a Magical Girl when she lead armies after hearing God's voice. He then takes notice of Mash and Chloe, and mistakes them both for different versions of Jeanne. Seeing he considers even Fou to be Jeanne, the group fight and defeat Gilles.

Next, they encounter Diarmuid Ua Duibhne in the Land of Snow and Honey, witnessing him crying blood as he tells all adult women to stay away. Diarmuid believes Magical Girls to be better than adult women as they possess a dauntless sense of duty and battle instead of manipulating like the former. Unlike Blackbeard and the Phantom's desire to be Magical Girls, he wishes to only serve Magical Girls loyally. After Mash and Chloe are advised by him to never become adult women, the group fight and defeat Diarmuid.

With the Magical Gentlemen defeated, the group return to the Neutral Zone, and prepare to return to Chaldea. However, some occurrence throughout the Reality Marble prompts them to go into the Land of Crystals and Stars, the former kingdom of the First Lady. . Inside the castle, they witness a girl form from shadows before them. The girl names herself Testament, and the group note how she looks exactly like Illya. Ritsuka asks her the purpose of the Magical Gentlemen, and Testament reveals their wishes made her able to come into existence. She is the crystallization of their obsessive desire for a pure and ideal Magical Girl. However, Testament shows herself to be absolutely impure with the desire to spread despair. After the group defeats her, she complains of the ridiculousness of her being the ideal Magical Girl who fulfills the wishes of all gentlemen. As she disappears, Testament reveals the group were summoned into the Reality Marble to serve as spectators and her enemies. She continues the alterations to the Reality Marble will be undone when she disappears, and the group will be returned to Chaldea once the Reality Marble returns to normal. After Testament disappears, the Reality Marble is returned to its original state, and the group return to Chladea.

GUDAGUDA Meiji Restoration
GUDAGUDA Meiji Restoration (ぐだぐだ明治維新) refers to an event which occurred during the aftermath of the Human Order Incineration Incident. It involved a unique Singularity that is a single point in time unconnected to the past and the future.

Setting
During the Battle at the Time Temple, the Demon God Andras developed self-awareness. In fear of his demise, he fled the Time Temple while the battle was still going on. He eventually drifted into a Singularity while in a near death state, where he died. However, his residual thoughts resonated with the powerful desire not to die, and fused with it to materialize as an existence similar to a Holy Grail. Needing to connect with the Spirit Origin of a Heroic Spirit to maintain his existence, Andras called out to those who shared his desire. The first of these was Hijikata Toshizou, who only recalls having been fatally shot at Hakodate. As he wandered the Singularity, Hijikata projected his desire not to die until he wins to Andras, who granted his desire and shaped the Singularity accordingly. However, Hijikata's version of immortality wasn't compatible with Andras's own, so Andras sought another to fuse with. He also summoned Oda Nobukatsu who shared his desire to bless all mortals with eternity. In accordance with this plan, Andras disconnected the Singularity from the past and the future. However, Nobukatsu needed Andras' power to maintain his existence, as he doesn't qualify as a Heroic Spirit. Still needing to fuse with a Heroic Spirit, Andras summoned Chacha, who only recalled being consumed by the flames of the burning, and tried to fuse with her. She escaped though, so Andras ordered to Nobukatsu to recapture, but she managed to escape the Singularity. While waiting for Chacha to return, Nobukatsu overthrew the Tokugawa Shogunate while pretending to be Nobunaga Oda, and created the Oda Shogunate a week before Chaldea's arrival. Meanwhile Hijikata recreated the Shinsengumi, who eventually came into fierce opposition with the Oda.

History
Ritsuka, Souiji Okita, Nobunga Oda relax in their room. Okita and Nobunga recount non-existent previous events when Mash Kyrielight barges in to alert Ritsuka of an intruder. A Mini Nobu then suddenly appears, but it's quickly dispatched by a masked person. They introduce themselves as Chacha, proclaim herself as a mysterious masked woman from another dimension to tell Ritsuka of an impending doom. She removes her mask when Nobunga finally recognizes her niece, remembering Nobunga was killed by Akechi in Honnoji. After Leonardo da Vinci tells the group Chaldea is infested with Guda Guda Particles, a particles that turns infected Servants into disappointments, the group rayshift.

The group arrive on a beach, and Nobunga quickly kills Edward Teach. Nobunga asks Chacha what time period they're in, but Chacha only knows it isn't her and Nobunaga's era. She then realizes Blackbeard wasn't the problem. Mash believes the era is near the Meiji Restoration. A Nobu Tank then appears to capture Chacha, but the group defeat it. A local fisherman thanks them for killing Blackbeard and the Nobu Tank he says is from the shogunate. He continues there's been endless fighting ever since the Oda Shogunate took over after defeating Tokugawa last week.

The group arrive in Kyoto, and eat a local restaurant when they hear some commotion. A villager tells them it's the Oda and the Shinsengumi fighting again. The group arrive to see a man claiming himself to be Nobunaga fighting another man, who Okita recognizes as Hijikata Toshizou. Hijikata demands she helps him, but she's confused about the situation and the identity of "Nobunaga". "Nobunaga" proclaims himself to be Nobunaga back from the dead when the real Nobunaga recognize him as her brother, Oda Nobukatsu. Nobunaga demands to know why Nobukatsu he made a new Oda Shogunate, to which he responds the people wanted a hero to save them from their decadent ways. Nobunaga prepares to punish him for taking her name, but Hijikata stops her as Nobukatsu is his prey. Okita manages to stop Hijikata while Nobunaga stops her brother. She decides to follow him to where he's camped after he withdraws his troops. Okita reluctantly decides to follow Hijikata to what she assumes is the Shinsengumi headquarters. She and Nobunaga then argue about who Ritsuka will go with. Regardless of which side they pick, Chacha follows whatever side Ritsuka picks.

After a battle between the Oda and the Shinsengumi, if Ritsuka joined the Oda, the group (except Okita and Hijikata) go to Nobukatsu's abode. Nobunaga decides to postpone her brother's punishment until they've defeated the Shinsengumi. While Nobukatsu meets with the weapons merchant with the funds Ritsuka gathered, the group decide to pay Okita a visit. Upon arriving at the Shinsengumi headquarters, Nobunaga and Okita get into arguement when the former mocks the building's sorry state. A Nobusengumi spy then hands a report toHijikata. The reports reads ronin are plotting to burn Kyoto, and they're secretly meeting at the Ikedaya Inn.

After a battle between the Oda and the Shinsengumi, if Ritsuka joined the Shinsengumi, the group (except Nobunaga and Nobukatsu) go to the Shinsengumi headquarters. Okita thanks Ritsuka for gathering the funds to make the Shinsengumi financially stable like it never was. Hijitaka sends them, with Chacha following, out on patrol, which they use a chance to visit Nobunaga. Upon arriving, Okita pities the sorry state of the Oda headquarters, which infuriates Nobunaga. A Nobusengumi messenger sent by Hijitaka then hands a report to Okita. The reports reads ronin are plotting to burn Kyoto, and they're secretly meeting at the Ikedaya Inn.

At the Ikedaya Inn, Saigou Edimori and Katsura Tesla argue about the superiority of their companies' products until their benefactor convicnes them to join them. Okita and Ritsuka then burst into the room to arrest them, which prompts the benefactor to make their escape. Okita tries to go after them, but a group of Mecha Nobbu block her. While Ritsuka and Okita fight the Mecha Nobbu, Nobukatsu, whose revealed to be Edimori and Tesla's benefactor, states aloud he'll become the Oda's official head if the inventors manage to kill Nobunaga. Unfortunately for Nobukatsu, his words were overheard by Nobunaga and Chacha. The two prepare to punish him when Tesla appears to attack her with Nobbu UFOs. Nobukatsu escapes while Nobunaga and Chacha are busy fighting. Meanwhile in the inn, Ritsuka and Okita continue fighting their way out through Mecha Nobbus. Hijitaka then arrives to help destroy the remaining Mecha Nobbus. After they're destroyed, Edimori surrenders, and captured to be interrogated later. Nobunaga and Chacha then arrive with a captured Tesla, who surrendered after the Nobbu UFOs. However, Edimori and Tesla flashbang the group, and escape when Nobunaga and Hijitaka were arguing. As they escape, Edimori reveals his factory in Toba is producing tens of thousands of Mecha Nobbu, and Tesla reveals company in Fushimi is test a powerful weapon. After Edimori and Tesla escaped, Okita collapses from overexertion.

Back at the Shinsengumi headquarters, a slightly recovered Okita thanks Ritsuka for taking care of her. Mash then appears, and explains to Ritsuka that they were heading to the Idekaya, she had Da Vinci analyze the Singularity. Speaking in private, Da Vinci reveals the Singularity is stasis, meaning it doesn't have a future. She continues the Singularity isn't a specific point in history nor is it an altered history, instead it is a single point in time unconnected from the past and the future. She initially assumed the Singularity was a parallel world's history that got derailed at some point. She realized its a world where time has stopped, and that someone deliberately made it so. Suddenly, Ritsuka overhears a commotion coming from Okita's room, and rush there to find out. They find Chacha arguing with Hijikata about taking Okita into battle to Toba-Fushimi when she isn't well enough. However, Okita joins him anyway, causing Chacha to leave, but not before giving medicine to Okita. The group then leave for Toba-Fushimi.

The group arrive at Toba-Fushimi to find Nobunaga there observing all the Nobbu Mechas and UFOs gathered. After Ritsuka explains Chacha ran off, Nobunaga asks Hijikata for his assessment of the enemy. He assess that the enemy outnumbering them leaves them with the only option of distracting them with a feint while another unit flanks. Hijikata decides Okita will lead the feint attack while he flanks the enemy. However, as Okita isn't well enough, Nobunaga decides she'll lead the feint attack instead while Okita and Hijikata lead the flank. As he watches the Mecha Nobbu and Nobbu UFOs being destroyed, Nobukatsu blames Ritsuka for the situation. Chacha soon arrives to see the battle's confusion when she sees Nobukatsu running off somewhere. She eavesdrops on him, and hears him speaking to someone ordering to kill Ritsuka. However, she alerts him to presence when she's shocked aloud by his mention of Taikou. He tells her that he was summoned to be Taikou's servants, and that he'll send her to the castle. Chacha recognizes Taikou is dead, but Nobukatsu tells her that death hasn't affected either of them due to the nature of the Singularity. Meanwhile on the battlefield, Edimori and Tesla disappear after they were defeated by the group. Nobukatsu then arrives carrying an unconscious Chacha. He reveals his true master is the Great Gold Demon Taikou, Toyotomi Hideyoshi. A golden castle then suddenly appears, to which Nobukatsu goes to with Chacha.

In an unknown location, a mysterious voice pleads with Chacha to return to the castle, but she refuses. The voice tells her that her children, and Toyotomi Tsurumatsu, are also here, and again pleads for her to return.

Meanwhile on the battlefield, the group prepare to rescue Chacha. Hijikata ponders about Demon Taikou, seeming to him as the identity of the voice he heard before. The group near the Sun Fortress when they were stopped by fortifications suddenly summoned by Sanada Emiyamaru. They fight Emiyamaru, Gotou Setanta, Mouri Medinaga, Mysterious Chousokabe Heroine X, Akashi Ex, all of whom were summoned by Taikou to obey Nobukatsu's orders while he sacrifices Chacha to Taikou. After all of Nobukatsu's generals disappear, the group continue onward to the castle. Nobukatsu reveals Chacha has already been sacrificed, and Taikou has been revived. He then shifts space to a cavern.

Nobunaga senses a massive amount of magical energy emanating from the Sun Fortress. Da Vinci then contacts the group, and reveal a Demon God is at the core the castle. She explains the Demon God is a corpse of one who died in the Time Temple that somehow drifted into the Singularity, or it fled to the Singularity while it was near death. Golden Demon Taikou Hideyoshi appears and announces the creation of an eternal golden paradise. Nobukatsu explains that within the Singularity, Taikou will bless all mortals with eternity. He then reveals he did of all this to free Nobunaga from her obligations to the Oda, so they can relive their carefree childhoods forever. Nobunaga rejects him though, so he sends wave after wave of soldiers to force her to understand. While Ritsuka, Okita, and Hijikata fight Nobukatsu's army, Nobunaga deals with her brother. After Nobukatsu's army is defeated, Nobunaga prepares to execute him, but she misses on purpose. She then calls out to Chacha, whose revealed to yet be consumed by Taikou. Chacha reveals how she's been hearing the voices of Hideyoshi and their children blaming her for the destruction of the Toyotomi. However, Nobunaga reminds her how Hideoyoshi was only kind to her. Chacha realizes Taikou has been deceiving her, and he asks her she would refuse to live forever with her family. Nobunaga reveals the Demon God had gained self-awareness during the battle in the Time Temple, then it fled in fear of its own death. It eventually drifted in a near-death state into the Singularity where it finally died. Da Vinci reveals Taikou is the manifestation of the Demon God's residual thoughts. It resonated with the powerful desire not to die, then fused with that desire and materialized as something to a Grail. Da Vinci then reveals it cannot maintain its existence without using the Spirit Origin of a Heroic Spirit as a catalyst. Realizing the Singularity will return to normal if they free Chacha, the group fight and defeat Taikou.

In a flashback, the Demon God's name is revealed to be Andras. Andras expresses his fear of dying, and his desire to live in his own world where he can relish his new self-awareness a bit longer. Chacha then appears before him, confused about where she is, and recalling the flames that consumed her. She then notices Andras, and he recognizes that she is also near death after the record that destroyed the Toyotomi. He asks her to let him fuse with her, but she refuses while denying she destroyed the Toyotomi. Andras realizes Chacha was falsely branded as the destroyer of the Toyotomi, and recognizes her as a fitting vessel for him. He decides that she is fit to be his accomplice, and reveals her powerful sense of shame guided him through the sea of death.

In the present, Andras realizes that Chacha will never accept eternity. While unable to understand humans, he also realizes life without purpose is meaningless. After Andras disappears, Nobukatsu begins to disappear as well. He explains he doesn't qualify as a Heroic Spirit, so he could only maintain his Spirit Origin thanks to Andras. After he disappears, Da Vinci and Mash tell the group to escape the Singularity, as it'll soon collapse without Andras. However, it isn't collapsing, making Da Vinci wonder if there's still a shard of Andras somewhere. Nobunaga realizes Hijikata has a shard of Andras, which he confirms. She reveals he was summoned by Andras, which he also confirms. He recalls how he was fatally shot at Hakodate, and the next thing he knew, he was in the Singularity. He wonders if Andras also consumed him, but Nobunaga explains Andras called out to those who shared his desire not to die. She continues Hijitaka is one of the keystones that created and maintained the Singularity, but unlike the others, he didn't need Andras' power. She theorizes if Andras had consumed Hijitaka, then the Singularity would have been more of a hellish battlefield. She then states Hijikata's version of immortality doesn't match with Andras' own, and that he didn't let Andras control his Spirit Origin. Okita wonders if they can talk Hijikata down, but Nobunaga tells her that not even Andras could release him from madness. She realizes Hijikata never realized he turned into a Heroic Spirit after his death. He continued to wander the Singularity's battlefields while projecting his desire not to die until he wins towards Andras. Da Vinci explains Andras granted Hijikata's desire and shaped the Singularity accordingly. Okita wonders if Hijikata intended to continue living while embodying the Shinsengumi forever. Hijitak realizes the group is trapped in the Singularity until he dies. Nobunaga confirms his realization, and offers to kill him if it's too hard for Okita. Okita rejects her though, and tells Hijikata that both he and the Shinsengumi. Hijikata however tells her that the Shinsengumi will live forever for as long as he lives. He then fights the group to determine whether his or Okita's Shinsengumi is the real one. With Hijikata's demise, the Singularity begin to collapse, so the group rayshift back to Chaldea.

In the still collapsing Singularity, Hijikata accepts that he died. Andras then appears and tells him to leave before the Singularity collapses completely. Hijikata wonders if Andras is concerned for him. He also regrets he wasn't more compatible with Andras, as the Singularity would've been better fortified otherwise. Andras confirms Hijikata's regret, and reveals that he learned to die lamenting the life that's been lost thanks to Hijikata. He sees this as the sole saving grace he received with his self-awareness. He continues he will disappear at the end of his drifiting while Hijikata will disappear at the end of his battle, as per the fate of his Spirit Origin. Calling Hijikata his beacon, Andras tells him to keep fighting, even though he knows he cannot be saved. He calls this Hijikata's punishment for briefly redeeming his evil, as well as his final wish. After Andras disappears completely, Hijikata states he'll accept whatever battlefield he's summoned to. Meanwhile in Chaldea, Chacha gives Ritsuka the Grail she took from Andras, and joins Chaldea.
