Shimosa Singularity

Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses (屍山血河舞台, Shizan Ketsuga Butai), 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 III), 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.

History
Ritsuka recalls to Mash their meeting with a female Musashi in a dream-like experience. Mash deduce this Musashi was from a culled parallel world, and she was travelling between worlds through special means. She even theorizes Musashi is a living person rather than a Heroic Spirit. She also says the female Musashi has no connection to the written by the male Musashi of their history. Ritsuka confirms the female Musashi they met was a living Servant. Intrigued by the fact there are two Muashis with differing histories, Mash searches for some commonality or absolute difference in the manuscript. Sasaki Kojirou is intrigued by a female Musashi being real rather than a manifestion of his legends, unlike him who is internally a manifestation of a legend about Sasaki. He deduces she's yet to reach the Void since Ritsuka said she never recalled the famous duel betwen Musashi and Saski on Ganyru Island. However, as Saski utter Musashi's other name: Shinmen Musashi no Kami Fujiwara no Harunobu, Ritsuka sees visions of a countryside and a burning building. They then collapse and goes into a coma.

Ritsuka wake up in a field, having been caught earlier by Miyamoto Musashi. Unsure if they're dreaming or not, she recalls stories where peoples' spirits leave their bodies when dreaming. A puppeteer told her that, while extremely rare, it is possible to travel to other worlds while dreaming. She guesses Ritsuka is likely dreaming while simultaneously the current world truly exists, or at least she assumes it does. Thus if they die before waking up, they will die in reality. Musashi then reveals she cannot return to worlds she previously visited. She decides to help Ritsuka return to reality, so she can continue her journey.

While searching for a village, the pair encounter a young girl carry a baby. The girl introduces herself as Onui and the baby as her little brother, Tasuke. As Onui mentioned Edo earlier, Musashi realizes it is currently the Tokugawa Shogunate's reign. She assumes they're in the Kazusa Province when Onui said it's half-a-day walk to Toke Castle from their current location. However, Onui corrects her that they're in the Shimosa Province, which confuses Musashi. She then realizes this Japan's history differs from her own when Onui confirms Iemitsu Tokugawa is the current ruler. Onui invites Ritsuka and Musashi to her grandpa's hermitage. However, the sky suddenly darkens, and the group are beset by spirits. After the spirits are destroyed, the sky returns to normal. Onui assumes the spirits were actually bandits since Musashi was able to slay them without being a monk, but Ritsuka and Musashi disagree.

As the group travel to her grandpa's hermitage, Onui says the spirits don't appear in there or the village, even at night. The sky then darkens again, but the spirits are quickly slain by a man with a single strike with his spear. He introduces himself as Hōzōin Inshun. The sky then darkens again, and the group slay the ensuing monsters. Afterwards, Inshun explains he was summoned two days ago, recalling he was alone at the grounds of Katori Shrine when summoned. After having a terrifying premonition, he left Katori Shrine, and wandered while slaying the spirits that apppeared at night and when the sky darkened. He assumes someone using a Holy Grail to summon the spirits.

At Katori shrine, a sorcerer declares the dark Jesuit sorcery they performed there has granted them control of seven knights from across space and time. He says they are not Heroic Spirits, but Heroic Spirit Swordmasters made to destroy the world. Caster of Limbo concurs, stating how he and other Heroic Spirits were summoned by the Grail and infused with his Curse of Annihilation. He explains the Swordmasters will obey the sorcerer's commands, declaring they cannot be hurt or killed by any blade. They will all in their path until every human is dead. Caster notes they're missing one though, which the sorcerer is aware of. He then order Caster to turn day into night.

Meanwhile with the group, day turns into night occupied by a blood moon. Sensing there will be greater danger than before, they hurry eastward to Onui and Tasuke's home. While cutting through a bamboo forest, they encounter the Swordmasters. Inshun tries to attack one of them, but a female Archer deflects it with an arrow. Caster then appears and declares the Swordmasters materialized to turn the world into a hell. Musashi is suddenly attacked by fire that she slashes away. She seemingly prevents an ambush from Assassin of Parasio, but it was merely her shadow. She then attacks Rider of Kālasūtra Hell aided by her Heavenly Eye, but her attack is blocked. Berserker of Saṃghāta Hell unleashes a wave of her special brew said to melt bodies. Inshun deflects it after Hazy Inverted Moon - Eleven Styles. A cold-blooded swordsman, who Musashi assumes to be the leader, then appears. He demands Inshun to be handed over, stating everyone will be massacred afterwards. Musashi recognizes she cannot defeat six of them yet alone even one. Inshun realizes they were after him and decides to hold them off long enough for the others to escape. After they escape, he fights the swordsman with the aid of his Noble Phantasm. He eventually pierces his heart, but finds he cannot move his spear. The swordsman reveals such attack would kill a human or Heroic Spirit, and introduces his Cursed Name as Saber of Empireo. Caster casts the Curse of Annihilation on Inshun on Saber's command. He reveals Inshun was summoned to serve as the seventh Swordmaster, but he was summoned with free will unlike the others. As Inshun is turned into a Swordmaster, he realizes the Swordmasters are unlike other Heroic Spirits.

The group continue escaping when they encounter Inshun. However he is now a Swordmaster, and declare himself to be Lancer of Purgatorio. Musashi decapitates him during the ensuing fight to protect Onui and Tasuke, but he gets up and reattaches his head. The group escape to the village, and hide in a nearby haystack. Inshun tries to antagonize Musashi by massacring the village. After leaving the haystack, the group head for the hermitage.

At the hermitage, the group meet Onui and Tasuke's grandpa, though he's a young man. Inshun arrives and attacks him, but he dodges and destroy Inshun's body with a single blow. Inshun regenerates and boasts there isn't any technique nor blade that reach the Spiritual Core of a Swordmaster. After regenerating from another attack from Onui and Tasuke's grandpa, he reveals he massacred the villages lying to the north and west. He claims his body is now a puppet controlled by karma. The only way to stop him is to destroy him completely. Musashi takes the sword Onui and Tasuke's grandpa recently made, feeling a divine aura from it. He considers it a fail, saying it can effortlessly cut through anything, but he pushed it into the realm of demons. Musashi then challenges Inshun to a duel to reach the apex of her mastery. Inshun responds by casting a spell similar to a reality marble of a field of corpses where the loser's soul will be consumed. Thanks to the sword she took earlier, Musashi was able to Inshun's Spiritual Core and kill him. The group then go into the hermitage.

Inside the hermitage, Musashi keeps the sword as an expection to her rule of four. Onui and Tasuke's grandpa explains it is a failure since it is an evil blade that reached the realm of demons. The ultimate blade he seeks isn't one that cuts flesh and bone, but one that can severs bonds, certainty, and karma. Musashi realizes she freed Inshun from his karma thanks to the sword. Onui and Tasuke's grandpa still considers it failure though since it cannot cut bonds or certainty. After Musashi asks for its name, he dubs the sword Myoujingri Muramasa. He then reveals he is Senji Muramasa, a Saber class Servant.

Later, Musashi asks Onui if she heard the name Muramasa before, referring to it as the bane of the Tokugawa. She explains Muramasa is a legendary swordsmith from Kuwana in the Ise Province, famed for forging cursed swords that devastated the Tokuwaga family. She continues he forged the sword that slew Ieyasu Tokuwaga's grandather, one that assisted in the seppuku of Nobuyasu Tokuwaga, and even a shoto that Ieyasu cut himself on. She concludes for those reasons any Muramasa-forged sword is feared as a threat to the Tokugawa family. After breakfast, Ritsuka and Musashi go to Muramasa's smithy. There he explains he never done any feats to make worthy of becoming a Heroic Spirit. He believes the gods summoned him into his current vessel to give him a chance to become one. He assumes his vessel's body, mind, and fated path are similar to his original self. He also believes he was a smith associated with the Muramasa school or a descendant of his. He then complains about being a Saber, saying he makes swords not use them. After wondering why he has a workshop as a Saber, he reveals he is a Rogue Servant summoned without Master. Musashi assumes he is like Inshun, but Muramasa says he was summoned by the gods. He explains he was summoned in Shimosa during the day in the middle of a rice field near the village approximately month ago. By the time he got to the village though, evil spirits had killed half of the village, including Onui and Tasuke's parents. After taking Onui and Tasuke in, he took the hermitage from the western village. Musashi asks him if there other villages around, to which Muramasa says there are some to the south. He then reveals the evil spirits appeared around the time he was summoned, saying they avoid places of worship. He continues he heard rumors of the spirits being commanded by the Swordmasters. He also recalls a rumor about a man performing dark Jesuit sorcery at Katori Shrine. His mysticism instantly turning day into night, and the Swordmasters emerged from hell to serve him and destroy humanity. Muramasa didn't believe the rumors, but he now understands they are real. He recalls hearing the Swordmasters razed the Hitachi Provice completely. Musashi decides they need more information on the evil spirits and the Swordmasters. Muramasa directs them to the town outside Toke Castle, which he also remembers being abandoned in Kazusa, as a place to get more info.

Ritsuka and Musashi then leave for Toke Castle town, taking Onui and Tasuke with them on Muramasa's request. Musashi assumes he wanted them gone so he could check on the villagers. Just as she gets confident about their journey, the sky darkens accompanied by evil spirits. After destroying them, the group continue onward. They eventually enter Toke Castle town, where they ask the townsfolk about the evil spirits. They learn no one takes the evil spirits seriously since they almost never appear near town. Ritsuka and Musashi realize they haven't heard about the village massacres. Musashi guesses rumors travel slow in times of war, and remarks a rumor during wartime would affect people's lives. She also considers the possibility of the castle controlling what information enters town. But she also considers the possibility of them secretly gathering information of the Swordmasters and their summoner. The group eventually encounter a geisha with Tamamo-no-Mae's appearance, but she calls herself Otama and doesn't known Ritsuka. She then invites the group to her establishment after seeing Ritsuka's outfit. Kiyohime suddenly appears and calls Ritsuka the person of her dreams. Castle warrior shows up and reveals she is the daughter of Lord Matsudaira Shimousa-no-Kami. Kiyohime refuses to return to the castle, and demands Ritsuka take her far away. She and Otama then get into a argument over Ritsuka, and eventually get into a fight. Ritsuka and Musashi eventually calm them down. After Otama and Kiyohime return to their respective abodes, the group encounter a missionary who looks like Edmond. Musashi finds it strange for him to be in town since during the current era of Japan, permitted foreigners were restricted to Dejima in Nagasaki. The missionary calls that a trivial matter similar to why no one paid attention to the group's scuffle with Otama and Kiyohime. He explains it is like when one sees perfect strangers who bear a strong resemblance to a acquaintance, or when one sees something out of the ordinary and dismiss it as unworthy of concern. He thus concludes there is little difference between reality and dreams. He then listens to Ritsuka tell him about the Swordmasters, finding it strange that Paraiso and Empireo are separate. He believes the names are modeled after more than Dante, and considers the one who named them as either foolish or blasphemous. He then directs the group to the alleyway where they'll meet someone they need to meet and leaves. There they find Fuuma Kotarou collapsed, so they take him to Otama's inn.

At the inn, Kotarou explains he came to bring Ritsuka back to reality. However, he was the only Servant who was able to make it. He tries to explain to Ritsuka that they're in a dream they cannot wake from when he passes out again. He wakes up though after hearing Ritsuka has been summoning in battle. He believes they are temporarily borrowing the shadows of the Servant's Spirit Origins. After he falls asleep, Musashi tells Ritsuka how one can see the faces of those they know on strangers when travelling to other worlds through dreams. Otama then enters the room and allows the group to stay until Kotarou recovers.

At Katori Shrine, Caster reports that Inshun is gone, and blames it on his incomplete summoning. However, he says Inshun succeeded in his role, but Saber calls refutes that since he failed to takes even a hundred lives. Despite that though, the Sorcerer says Inshun still served as an excellent cornerstone for the Onriedo. He calls the system similar to the Holy Grail War Caster told him about, as the souls of Swordmasters who perish will reside in the foundations of his Onriedo. Caster explains the souls of a few Heroic Spirits are insufficient to manifest the Onriedo. Thus they need to kill more to help it grow with the souls of those drenched in bitterness, envy, and grief. He continues that is why the Heroic Spirits Swordmasters were granted the Curse of Annihilation made from his technique and the Sorcerer's power. A swordsman then enters the shrine; Caster explains he is the Sorcerer's bodyguard despite being human. The Sorcerer explains he met him in the mountains of Hitachi and brought him back to serve as his bodyguard on a whim. He then commands the Swordmasters to continue killing while he prepares for the arrival of the Onriedo. After he leaves, Caster and Saber realize he doesn't see Musashi as a threat. Caster then calls Katou Danzo, who insists she will kill Ritsuka and Musashi. Saber tells her to bother since she wouldn't stand a chance against Musashi, as she is a puppet not a Heroic Spirit. Caster orders her to sick Archer of Inferno on Musashi. He also orders her to closely observe a group of samurai from Edo that'll soon arrive in Toke Castle by pretending to be on a secret mission from the Shogunate. Once Caster determines everything is set, Danzo will bring Archer and Musashi together, and witness to what comes next.

At the inn, Ritsuka and Musashi sneak out after she sensed a disturbance outside. They arrive outside to find evil spirits; Musashi assumes they're out for revenge for Inshun. After slaying the spirits, Musashi senses the Swordmaster who commanded them nearby. Archer then unveils and introduces herself with her Cursed Name. Ritsuka asks about the Swordmasters' goal. She answers it is to kill and burn everything related to Tokugawa society. She threatens Musashi with prospect of showing the charred remains of those she cares for. She then starts unleashing fire, so Musashi fights her to ensure her fire doesn't spread. The two are unable to overwhelm since Musashi can't close the distance thanks to Archer's arrows and flames, while Archer's arrows are continuously deflected by Musashi at the last moment. Musashi realizes Archer is holding back, as she has yet to use the spell Inshun used. Archer admits it is because she was told to hold back, then vanishes with the promise of fighting Musashi in full force. Ritsuka and Musashi then return to the inn to rest while thinking of how to deal with Archer's flames.

Later into the night, Archer and Danzo encounter an old couple while on the road. To Danzo's surprise, Archer doesn't kill them instead has a friendly conversation. As the old couple leave, Danzo wonders if the Curse of Annihilation is no longer affecting Archer. However, after she confirms there is a village in the direction the couple are heading, Archer decides to massacre it. Later, Danzo reports on how the karma mechanism guiding the Curse of Annihilation is too effective on Archer. She details how Archer burned and massacred the village, with the exception of the old couple. After Archer explains it was because of her friendly conversation with them, Danzo realizes she has gone mad as she watched her walk wreathed in flames while speaking nonsense. She find no trace of the kind woman Archer was earlier, as she witnessed her massacre village after village. She fears she will endanger Toke Castel, a pivotal part of Caster and the Sorcerer's plan, by returning to town. She decides to stop her when Caster contacts her and agrees with sentiments.

At Toke Castle town, Kotarou has recovered some but not fully. The group then notice a commotion and go to investigate it. They learn a large procession of samurai has recently arrived from Edo. One of them samurai, Sakon, tells the townsfolk to be quiet and pay attention while his superior, Tajima-no-Kami, speaks. A aged warrior then introduces himself as Yagyū Tajima-no-Kami Munenori, chief inspector for the shogunate. He explains he and the other samurai have come on a official mission from the shogunate to bring the monsters, who he believes are just bandits, slaughtering innocents in southern Shimousa to justice with Matsudaira's cooperation. He also promises the mistakes of the Shimabara Rebellion will not be repeated with him around. He then confronts Musashi, recognizing her and asking her why she is in Shimosa. Musashi is surprised he is the same one she met before, but she refuses to answer his question. Yagyu recalls how they fought six months ago, but that is only from his perspective. Musashi finds it strange she is the same time and place from six months ago since she has never visted the same place twice before. Yagyu then paralyzes Ritsuka with a gaze, but Kotarou gets them to relax to undo it. Yagyu decides to duel Musashi to determine what she is up to when monsters fly in from the south. He paralyzes them with the aura of his sword ki before Musashi cuts them down. As another wave comes, he orders Sakon to get the townsfolk out of the vicinity. After slaying them monsters with the group, Yagyu assumes they were a scouting party, and orders Sakon to tell Matsudaira to deploy archers. He also orders to concentrate their forces to the south, believing the castle can have the bare minimum of soldiers. After the samurai leave, Yagyu finds it unusual for monsters to band together. Musashi explains it is because someone is leading them, and warns they may return in greater numbers in the future. Ritsuka then tells Yagyu about the Swordmasters and their assumption that Archer is leading the monsters. Yagyu then tells the group that a hundred of his finest men will confront Archer as a diversion while they ambush her from behind. He advises them to go through the mountain pass to do so. Danzo then arrives, and Yagyu explains she is the spy who saw Archer leading the monsters. He also says she will serve as the group's guide throught the mountain pass.

As the group walk the mountain pass, Kotarou realizes Danzo is a puppet. She confirms she is one animated by machinery that is over a hundred years old. Ritsuka realizes she is similar to a homunculus or golem, which Kotarou confirms. He also assures them that she is indeed a living person from the era. He realizes she doesn't remember, but he doesn't explain when he senses incoming monsters. After slaying them, the group soon arrive at their destination. There they witness Archer incinerate a number of samurai, but they arrive in time to stop her. Kotarou tells Danzo to take the injured to safety, and give the others new orders since they cannot stand against a Servant. Archer doesn't seem to recognize Musashi despite fighting her the previous night. Musashi asks her what she is hoping to accomplish by burning everything, as nothing in the era should affect her personally since it isn't hers. Archer claims she is nothing but firewood now when Musashi suddenly attacks her. In response, Archer goes berserk, releasing a strange magical energy. Kotarou and Musashi both realize she is an oni. When she begins shouting, Musashi realizes why Archer hates Japan since the Tokugawa are said to be descended from the Seiwa Genji. She explains Kiso Yoshinaka was a general who helped

overthrow the Taira regime, only to be persecuted by him afterwards. She reveals Archer was his wife who fought alongside him, Tomoe Gozen. She then readies to fight her with Myoujingri Murasama, and Tomoe takes them both to the other plane for their duel. After she is defeated, Tomoe remembers Yoshinaka's smile when he asked to stay away from the battlefield in order to spare her life, as

on Yorimoto's orders was after him. After giving birth to their son, she lived her days as a nun praying for Yoshinaka to rest in peace. With Tomoe's demise, the monsters are sent into disarray. The group then go help Danzo and the samurai deal with the remaining monsters.

Later, Musashi complains to Tasuke about how Yagyu commanded her to search for any remaining monsters immediately after killing Tomoe. However, she was able to find any. She then remarks how she is trying to reach the void with her swordmanship to surpass her father. She doubts herself though since she yet to reach it after all of her traveling and battles. She believes her battles with the Swordmasters is her final chance to reach the void. She then returns to Otama's inn, where she challenges Kotarou to a duel outside since he's fit enough for battle now. After the duel, they notice a crowd gathering around a nearby ichimai-zuri seller. The sell tells the crowd that a letter was sent to Toke Castle, threatening to assassinate Kiyohime. The group decide to head to Toke Castle, hoping Yagyu will let them in.

At Katori Shrine, Assassin reports that she has delivered the letter regarding Kiyohime's assassination to Toke Castle. She continues that by now, ten of Yagyu's samurai should be guarding Kiyohime now, and rumors should also be circulating. The Sorcerer states how Tomoe planted the seeds of unease in Shimosa, believing none can rid the populace of their fears. He orders Assassin to assassinate Kiyohime after letting panic about her assassination to spread throughout the population. Afterwards, the populace will be instilled utterly with fear, thus their souls will be better sacrifices. The Sorcerer then leaves after telling Assassin to become fear itself, and to trust the serpent within her. The swordsman asks Assassin what the Sorcerer meant by "the serpent within her", but she merely reminds him of his duty to guard the Sorcerer. After the swordsman leaves, Berserker mocks Assassin for trying to hold the cold dutiful demeanor of a ninja. Assassin realizes she is speaking with an illusion while the real Berserker will sitting next to her silently. She feels the curse inside her, the source of the illusion, begin to swell up. She then boasts she will kill more than just Kiyohime at Toke Castle before the night is done.

Inside Toke Castle, the group wait to meet with Kiyohime. They recall how Muramasa reprimanded them for keeping Onui and Tasuke two days longer than they were supposed, and leaving the children alone when they left to deal with Tomoe. Otama agreed with him since she had allowed the group to stay single night at her inn, yet they stayed another. Muramasa then took the children back to his hermitage, offering to let the group stay there. Ritsuka and Musashi decided to go there once their business at Toke Castle is done. The two tease Kotarou about Danzo when Kiyohime enters the room along with Yagyu. Kotarou realizes Kiyohime isn't a Servant like the one in Chaldea, even with their similarities. He then becomes concerned about the true nature of the Singularity, as he has yet to see distortions in history by the Holy Grail. He feels there is something fundamentally about the foundation of the world. Kiyohime t thanks the group for stopping Tomoe and her monsters on behalf of her father and the people of Shimousa, promising they will be rewarded for their achievement. She then tells them how many killed when the letter threatening her life was delievered. Despite having the castle guards and 300 of Yagyu's samurai, all of whom were involved in the Shimabara Rebellion, to protect her, she asks the group to protect her also. Yagyu allows this, regardless of his reservation about their social standing. Kiyohime pays Musashi 30 ryou to spar with her to prove the results of her marital arts. She then orders Danzo to fight with her after Musashi warned her not to fight her alone, even though she'll be going easy on her. After the fight, Musashi stays with Kiyohime, while Koatoru guards Ritsuka in their room. He then senses a Swordmaster has infiltrated the castle. He and Ritsuka then arrive outside to fight Assassin after convincing the warriors who survived against her not to fight her. Assassin declares her master, the Sorcerer, will wield the power of Satan to sacrifice Shimosa to destroy this world created by the Tokugawa. She explains she will assassinate Kiyohime to devastate Shimosa's people in order to make Shimosa easier to destroy. She threatens to decapitate Ritsuka and show their head to Kiyohime before killing her. She then easily kills ten castle guards, adding her total victim to forty, with her snakes. Afterwards, she fights Ritsuka and Kotarou. After Kotarou decapitates her, Assassin decides to stop holding back. Musashi suddenly throws Myoujingri Murasama at her, only for it to miss and be caught by Kotarou. He then blocks the kunai Assassin threw at Kiyohime, who followed Musashi outside. Musashi slashes at Assassin, only for it to be an illusion while the real one had already escaped. Kotarou believes they can deduce Assassin's True Name since they aren't many famous Kunoichi. But he's reminded how numerous historical figures were thought to be men, only for them to actually women. Danzo then appears and tells the group that Yagyu will arrive momentarily with an assembly of his samurai. Kiyohime then faints after Ritsuka told her twenty castle guards were killed by Assassin.

At Katori Shrine, Caster says reports Assassin and Danzo have helped laid the groundwork for the Onriedo. Saber responds that fear is spreading throughout Shimosa, and the great pentagram being drawn in secret via Jesuit sorcery is nearing completion. The Sorcerer and his guard then arrive. The Sorcerer tells the others that Assassin had succeeded in spreading fear among populace, and all that remains is to remove her. Meanwhile in Toke Castle town, Assassin encounters Berserker. She proceeds to connect Assassin's heart and brain to power of the god of Mt. Ibuki,, that resides in her to the former's protest. She apologizes for her act, explain the Sorcerer needs Ritsuka and Musashi eliminated.

At Toke Castle, Yagyu orders his samurai to increase security. Assassin then returns and proceeds to summon Orochi with her curse. Musashi and Kotarou slay it when Kiyohime suddenly attacks Ritsuka with her fire. Kotarou manages to protect them from the flames though with his own body. Kiyohime tells the others her regret over destroying serpents nest, but the serpents never forgave her and kept coming after her. Orochi then revives despite being reduced to ash by Kotarou's Immortal Chaos Brigade due to Assasin's Saigyou revival technique. Assassin then tells Kiyohime to kill the group, saying the serpents will forgive her then. Afterwards, she will kill her to finally give her peace. Kotarou realizes the kunai Assassin threw at Kiyohime last night were merely a feint, and her true objective was to put Kiyohime under a spell. The group then fight Kiyohime and Orochi. After Orochi slain again, Kiyohime says she shouldn't have intruded on its domain, Mt. Ibuki. She realizes though she has never been to Mt. Ibuki, but her distant ancestor who committed the sin. She continues her ancestor's cursed blood courses through her, and believes the gods will forgive her if she kills the group. Ritsuka and Musashi realize someone else is speak through Kiyohime. Musashi recalls Kiyohime's affinity with snakes, and realizes the words she spoke earlier were from Assassin, Mochizuki Chiyome. She recounts the tale of how Kouga Saburou, lord of Oumi Kouga, was transformed into a snake after searching long for his wife who went missing on Mt. Ibuki. It was Orochi who cursed him as punishment for intruding on its domain. Musashi doubts Chiyome is Saburou himself, and recalls the Kouga Mochizuki family carried his cursed blood. They eventually produced Chiyome, who served as 's spy during the Warring States period. Chiyome expresses how her curse will never leave her, even after becoming a Heroic Spirit or aSwordmaster. She then brings herself and Musashi to the other plane for their duel. After Chiyome is killed, Kotarou pick up her kunai that didn't disappear with her since they were procured in Shimosa. Musashi recalls her saying something about the Onriedo, a Buddhist word for distancing oneself for this impure world and its earthly desires.

The group travel back to Muramasa's hermitage, accompanied by Danzo. She explains her new orders from Yagyu are to gather information around Shimosa and to ensure the group arrive safely at their destination. She then expresses concern about the injury Kotarou suffered protecting Ritsuka while she was outside the castle on Yagyu's orders. Going on ahead of the others, she wonders why she cares since her orders were merely to learn about the group. She then recalls Berserker collecting Orochi's remains at Toke Castle for her wine. After collecting the remains, Berserker asked her what she truly desires before proceeding to Arakawa. Danzo then witnessed Rider slaughter an entire army of 10,244 men on east bank of the Arakawa River while they were en route to rendezvous with Yagyu. The only survivor is a young soldier who is left mentally broken by the slaughter. Rider decides not to kill, believing he would make a poor sacrifice. She then departed for Sagami with Berserker to unleash her Noble Phantasm upon it. Danzo reminded them that they weren't ordered to do so, but they ignored her.

At Muramasa's hermitage, Muramasa tells the group that he heard monsters have returned to Shimosa. He also tries to tell them about an army being slaughtered near the Arakawa River but stops since Onui and Tasuke are present. After supper, Danzo puts Onui and Tasuke to bed so Muramasa can tell the full story that he stopped before He explains an army sent from the shogunate were slaughtered near the Arakawa River, with the excepion of a single young soldier. The soldier crossed the river and relayed that two beautiful women were responsible for the slaughter before dying. The group deduce the two women are Swordmasters. Muramasa then reveals the entire Sagami Province was also destroyed. He continues the two women aren't in Sagami anymore, saying they went on a killing spree until high noon. Because they vanished by then, smaller villagers were spared, but larger places like Kamakura or Odawara Castle town were nearly massacred. He then examines Myoujingri Muramasa and determines Musashi already killed two other Swordmasters. The group then suddenly hear Onui screaming from outside. They rush out there to find her and Tasuke captured by Berserker and Rider. Ritsuka recognizes them as Shuten-douji and Minamoto no Raikou respectively, but they aren't the ones from Chaldea. After the group slay the monsters summoned by Raikou, Muramasaa steps outside and asks Ritsuka to save the children. Kotarou offers to conceal his presence and sneak behind the two Swordmasters. Danzon however warns against it, pointing out they're plotting something. After the children are passed to a monster, Musashi attacks Shuten, but Raikou blocks with a flick of her wrist. The Swordmasters then proceed to fight the group. Using only a fration of their power, the pair easily overwhelm them. Raikou tells them to come to the peak of the nearby mountain before high noon if they wish to save the children. After they escape, the group, prepare to go to the nearest mountain.

On the mountain, Shuten contemplates killing Onui, but Raikou stops her as she is a child. She then tearfully apologizes to Onui for how she treated. She continues the Spirit Origins of the Swordmasters were shattered and rebuilt to become what they are. She says they're broken because of it, so they says things they don't want. Shuten refutes this however, believing Raikou broke as a human long ago.

Meanwhile at Muramasa's hermitage, Muramasa forges a new sword. After he is done, the group leave for the mountain. They cut through the nearby bamboo forest when Danzo warns there are monsters up ahead. She advises against going around them, as it would cost more time, so the group slay them. As they continue onward, Kotarou explains Shuten and Raikou are bit different from the other Swordmasters since they were oni or oni-blooded in life. Musashi then describes the different types of oni. The first are creatures outside the domain of humans. The second are descendants of abominations possessing power outside of human capacity; The third are beings whose hatred of the world gave them corporeal form, and they cannot be pacified. Some of them are born like that because how stories portrayed them. Musashi then compares the two first types to Heroic Spirits in how they both exceed human capability. As for the comparison to the third type, Kotarou explains some Heroic Spirits were born from stories while others became monsters because of stories. A oni born from hatred then suddenly arrives, but the group manage to slay it. As the others resolves, Danzo is reminded how Kotarou told her a soulless ninja is just a hollow blade. The group exit the forest into a mountain trial. Muramasa recalls the atrocities committed during the age of war, but he's glad peace will come after looking at Ritsuka. He then reveals he cannot remember his children or grandchildren since he was so focused on forging swords. He expresses his desire to see Onui and Tasuke grow up, which is why he is doing everything to ensure their future. Orochi then suddenly appears, even though Chiyome is long gone. Kotarou realizes Shuten is able to summon it because she is a descendant of Orcohi. With the last of its energy, Orochi knocks Ritsuka down a slope. Kotarou goes to save them when another Orochi appears.

Ritsuka find themselves in a cave, having been knocked unconscious while tumbling down the mountain slope. They quickly realize Shuten is the cave with them. Shuten explains she found them while walking around after Raikou kicked her off the peak. Ritsuka asks her Onui and Tasuke are safe, but she isn't sure if they are at the moment. They then thank her for patching up their ankle. Shuten tells the final Swordmasters, Saber and Caster, are far worse than her and Raikou. She also says they're stronger as well, explaining one is utterly cold and efficient in their killing while the other would like to see the world end. She then offers Ritsuka anything they want if they join her. Ritsuka answers they want Onui and Tasuke's return, but Shuten refuses and begins tearing into their stomach. They eventually fall unconscious from the pain. Meanwhile on the peak, Raikou sings a lullaby to Onui and Tasuke, but they both wake up. After seeing she reminds Tasuke of his mother, she expresses his desire to be a mother even as a Swordmaster.

Musashi, Kotarou, Muramasa, and Danzo eventually find Ritsuka. Kotarou uses his clan's secret ointment to close their wound. He tells them to get some rest, saying Muramasa and Danzo are keeping a watch outside. After getting more rest, Ritsuka continues onward to the peak with the others. There the group confront Shuten and Raikou, and demand the children back. Shuten says she ate them, but the group have their doubts. They then kill the Orochi summoned by her. Afterwards, Shuten and Raikou bring Musashi to the other plane for their fight. After Shuten disappears, Raikou tells the group that Onui and Tasuke are in a small shrine up ahead. She confirms Shuten was lying before, saying they didn't harm either of them. She believes she is broken as a Swordmaster as she couldn't bring herself to harm the children, which she is glad for. She then asks the group to apologize for her to Onui for tying her up and roughly cutting her bounds. She also asks them to defeat the Swordmasters and prevent the Onriedo's arrival. After she disappears, Kotarou arrives with Onui and Tasuke, both of them unharmed; Muramasa gives Raikou's message to Onui. As the group leave the mountain, Kotarou realizes this world's divergence from the original history didn't begin in Shimosa nor Toke, as Danzo is still operational. Meanwhile at Katori Shrine, the Sorcerer orders Caster and Saber, the only ones who retained their sanity, to finish the ritual for the Onriedo.

Outside Toke Castle town, the Sorcerer prepares to materialize the Onriedo. On his order, Caster plunges the world into darkness and replace the sun with a blood red moon. The Sorcerer then uses the souls of five Swordmaster and those they killed to transform Toke Castle into Onriedo Castle. Townsfolk are randomly turned into monsters and kill those who weren't turned due to Caster's Noble Phantasm. For those who lack resistance to magic have their human norms to bestial urges, and begin eating other humans. Among those killed is Sakon, who was killed by a child turned monster. The Sorcerer calls him a hypocrite for having been horrified by the carnage when he committed such atrocities in Shimabara barely a year ago. His identity is revealed to be Amakusa Shirou Tokisada. He is not the Heroic Spirit Amakusa Shirou recorded in Chaldea, but a human who survived the Shimabara Rebellion in a now culled parallel world. As he traveled across many worlds, his grudge towards the Tokugawa until he became the living emodiment of hate, something beyond human. He then followed the calling of something that reach out to him, and arrived in this particular version of Shimosa.

Meanwhile at the hermitage, the group see the blood moon, and assume another Swordmaster has arrived. Danzo sends up a flying ovservational device, and sees that Toke Castle has been transformed. The group, along with Muramasa and the children, then ride to town on the horses that Muramasa provided. Upon arriving, Kotarou scouts on ahead and assumes the castle is the cause of the monsters in town. He also says a number of the townsfolk were turned into monsters. Danzo confirms the eastern area has been completely wiped out. Since the east is closer to the castle, the group assume people turn monsters when they get close to it. They then notice Otama helping people evacuate. After they slay the monsters that arrived, Otama confirms most of the survivors have already escaped since an hour from when the carnage began. She also says Yagyu and his samurai fought monsters long enough for the survivors to escape. She then tells the group that she saw Kiyohime's servants fleeing from the castle, seeking refuge at the Town's outskirts. Muramasa then leaves Onui and Tasuke in her care, as it would be too dangerous to take them to the castle. After they leave, two Orochi arrive. After the group slay one, they encounter the Missonary who was fighting the other Orochi. Kotarou then tries to ask him if he's from Chaldea, but he's cut off. The Missionary reveals Amakusa Shirou is preparing to use Onriedo Castle for a ritual. He also reveals Kiyohime is being help captive there. He continues that Amakusa Shirou plans to cast a far-ranging multilayered curse on the Tokugawa regime, one so powerful it'll threaten the stability of many parallel worlds. As his aim is to curse every possiblity of Tokugawa regime, Amakusa Shirou plans to use Kiyohime as the perfect catalyst due to her Tokugawa heritage. Though she lacks blood from the immediate family, it will serve sufficiently for his plan, especially given that Iemitsu is only the third shogun. The Missionary realizes Amakusa Shirou was searching for a parallel world where Matsudaira's daughter was living near Edo following the Shimabara Rebellion. He then reveals that once Kiyohime is sacrifice to the castle, it will be complete, and this world, along with many others, will be destroyed. The group then rush towards the castle to save Kiyohime and stop Amakusa Shirou.

The group arrive outside the castle, hearing a subtle heartbeat from it. Breaking through the monsters that materialized, they enter the castle courtyard, guided there by Danzo. There she tries to confess she is an enemy spy, but Musashi reveals it before she can. It is revealed the group suspected her at different times; Musashi and Muramasa from the beginning; Kotarou after Chiyome's demise; Ritsuka after Onui and Tasuke were abducted. Danzo reveals Saber commanded her to aid the group against the Swordmasters, and Caster ordered her to kill them if the chance presented itself. She confesses her surprise at feeling remorse for letting Shuten and Raikou kidnap Onui and Tasuke. She is surprised that despite the group knowing she was an enemy spy, they still let her accompany them. She recalls Kotarou telling Chiyome that a souless ninja is just a hollow blade, and realized she is neither of them. Beliveing to have gained a soul now, she says she led the group to the castle on her own accord to prevent its activation. Caster appears and mocks her for thinking she gained a soul and led the group of her volition. He reveals he repaired her after finding her broken and abandoned body, having shutdown from a lack of magical energy. While he repaired her bdoy though, he also altered her mental records. He then proclaims himself to be Abe no Seimei, though the group doubt its validity. Musashi attacks him, but a barrier stops him. Danzo also tries to attack her from behind, but she stopped by Kotarou. Danzo finds she cannot control herself, and realizes Caster was controlling her actions the whole time. Caster then calls the monsters that he's been keeping at bay, which is why the group never encountered any in the castle so far. He also Danzo fight the group, revealing he imbued with a sorcery that recreates the Curse of Annihiliaton's karma through machinery. The group slay the monsters, but Danzo is too fast for them. After thanking them for treating her like a real person though, Danzo self-destructs herself. The explosion takes out Musashi's eye while leaving Danzo in critical condition. Ritsuka is able to stop the bleeding with their Mystic Code, but they weren't able to close the wound. Muramasa suspects the reason Musashi's eye couldn't be healed is because of a curse that Caster imbued Danzo with. Musashi attacks Caster with a slash that should have cut his head clean off, but he stops it. He mocks her sword technique and the fact she is wearing a eyepatch, then he summons more monsters. Kotarou is then imparted with Danzo's magical energy, the very same that the first Kotarou embedded into her. He then helps the others slay the innumerable monsters summoned by Caster. Caster mocks Kotarou's efforts, claiming he cannot be harmed as long as Onriedo Castle has Satan's protection. Kotarou counter he and the others already slain 90% of the monsters protecting, so they only need to kill a few more before he can kill Caster. Caster then casts the Curse of Annihiliation on Musashi to transform her into a Swordmaster. Ritsuka however uses the Mystic Code Rain of Isis to remove the curse to Caster's shock. Musashi uses this oppurtunity to slash him, breaking through his multilayered barrier. Caster then summons the great spirit of the Souma clan to fight Musashi for him after bringing them into the other plane. After Musashi slays the spirit, Kotarou wounds Caster, who claims only the Myoujingri Muramasa should be able to harm a Swordmaster. Kotarou reveals it is thanks to Danzo passing her will to him that he was able to do so. He also reveals Danzo was the one who taught him his clan's ninjitsu, considered her to be his mother in everything but blood. He then seemingly finishes off Caster.

Meanwhile, inside the castle, Amakusa Shirou declares Onriedo Castle will destroy Chaldea after it destroys Shimosa. He reveals to a confused Kiyohime that he spent twenty years travelling acorss different worlds before hearing Satan's voice calling to him. He then tells her that the Tokugawa is always the no matter the world, repeating the massacre of christians at Shimabara across several worlds. Thus, he will kill every Tokugawa mercilessly despite knowing this world is cut off from the proper history. He then tells the guard that Musashi is in the castle. He declares he will kill her, believing it is the sole reason for his existence. Though she wields the Myoujingri Muramasa, Musashi is still human and has yet to reach the pinnacle of her swordsmanship. Amakusa Shirou's guard has already reached the panniacle of his swordsmanship though. His guard is concerned he may not get the chance to duel Musashi since she will be facing Saber first.

Mash, Leonardo da Vinci, and Sherlock Holmes make contact with Ritsuka. Da Vinci reveals that after they fell into a coma, something intervened into dream Ritsuka was having and brought their consciousness somewhere else. Since Chaldea already had data of a similiar situation, they were able to surmise what happened, but they couldn't reach Ritsuka. The only thing that eventually worked was rayshifting Kotarou. Kotarou deduces it worked because Danzo, who has a strong connection with, existed in this world. He also realizes the spell meant to restore Ritsuka's comms he brought with him was activated when he absorbed Danzo's magical energy. Da Vinci doubts communications will not last long since that world is outside the proper history. Sherlock explains Ritsuka's mind was able to attain something similiar to a physical body after being transported. Even though the body is only temporarily, if it didn't adjust this world, Ritsuka's magic circuits wouldn't function properly to restore their comms. Ritsuka realizes Shuten may restored their magic circuits when she punctured them, suspecting the slim chance she shared memories with the version of her in Chaldea. Sherlock then reveals Ritsuka was brought into the rift between reality and dreams. He explains that particular version of Shimosa isn't a Singularity, instead it is something akin to a Reality Marble, a seperate timeline, or an alternate world that possseses no threat to humanity. He then explains Musashi is a Mobile Singularity, but she isn't the only factor responsible for what happened to Ritsuka. As the group think about who could be the other factor, Sherlock gives an example of when multiple Mobile Singularities being in the same world. Such a phenomena would result in any number of abnormalities and unusual phenomena. Ritsuka and Muramasa deduce Amakusa Shirou is the other Mobile Singularity. Kotarou realizes monsters manifested in Shimosa when Amakusa Shirou and the Swordmasters arrived, with more appearing when Onriedo Castle manifested. Sherlock then says he originally hypothesized that Musashi would be able to control the monsters like Amakusa Shirou can. She couldn't though, so he suspects Amakusa Shirou has a stronger Mobile Singularity temperament than her. After communications end with Chaldea, the group enter the castle keep.

Inside the castle keep, the group ascend it as they slay any monsters in their way. They eventually reach the fourth floor when a still alive Caster tries to ambush Musashi. However before either he or Musashi can do anything, Saber kills Caster. Saber then reveals himself to be Yagyu, the only human among the Swordmasters. He the reveals his loyalty to Iemitsu, and his devotion to his family's Shinkageryu were destroyed when he and Musashi dueled six months ago. He previously thought there was no special meaning to the way of the sword, nor any vaule in life, until he dueled Musashi. He realized at that moment he enjoyed dueling, so he joined Amakusa Shirou for a chance to duel Musashi again. Musashi asks the others to go on ahead without her, but Ritsuka decides to stay with her. After Muramasa and Kotarou ascend to the fifth floor, Yagyu bring Ritsuka and Musashi to the other plane for their duel. Eventually Musashi is able to awaken her ultimate techinque, Kengou-Battou: Ishana-Daitenshou, to breakthrough Yagyu's god-like swordsmanship. Yagyu then dies thanking her for the duel.

On the fifth floor, Amakusa Shirou prepares to sacrifice Kiyohime when Muramasas and Kotarou arrive. Muramasa realizes the Counter Force summoned him to this particular Shimosa was to stop Amakusa Shirou, who became a threat to the world. Amakusa Shirou declares his body has long surpassed human limitations, equal to that of a Swordmaster. He then proclaims he will destroy possible world where the Tokugawa exists as Satan guided him to. Kotarou and Muramasa attack him, but their attacks are useless. Ritsuka and Musashi then arrive to help. Amakusa Shirou finds himself and Musashi similiar in that they're no longer truly human after crossing many worlds since they cannot return to their own. Musashi admits they are similiar in that respect, but she travelled out of a sense of freedom, unlike Amakusa Shirou who sought revenge. She and the others then proceed to fight Amakusa Shirou. Eventually he entraps the group inside his Reality Marble, Shimabara Hell. It is recreation of Amakusa Shirou's original world engraved into his soul, where the very air is poisonous. Contacting the group from outside, Amakusa Shirou explains it doesn't suffer any living person to survive, and there is no escape from its waves of suffering and resentment. He then declares Onriedo Castle is now ready to retrieve its sacrifice. In response, Muramasa forges Tsumugari Muramasa, the same sword removed from Orochi's tail during the Age of the Gods, to bisect both the Reality Marble and Onriedo Castle. As the castle burns around them, Amakusa Shirou asks Muramasa how his sword could reach outside the Reality Marble. Muramasa answers it is because Onriedo Castle shares part of its name with Edo Castle. He also says the name Muramasa is synomous with the Tokugawa's downfall. He admits Amakusa Shirou would have succeeded if he didn't rhyme the name of his castle with the Tokugawa's own. Kotarou then pierces Amakusa Shirou's heart with the kunai that Chiyome left behind, and finishes him off. Deducing Ritsuka and Musashi on the otherside of the keep, Muramusa tells Kotarou to escape with Kiyohime. He advises jumping down to street level since she would suffocate from the smoke if they take the stairs. He then disappears since he used a divine sword without the body of a god.

Meanwhile, Ritsuka and Musashi try to escape from the burning castle. They are confronted by Amakusa Shirou's guard, Sasaki Kojirou, who has come to kill Musashi. She tells Ritsuka escape without her, and senses Sasaki is several times stronger than her. Despite having never met him, Musashi knows his name, and senses he is her fated rival. It doesn't when and where, Musashi and Sasaki are destined to fight. Though the duel itself is void of meaning or purpose, it doesn't matter to the two warriors. Musashi and Sasaki both agree the only possible outcome of their meeting is to fight. As their duel continues, their sword techniques are evenly matched while surpassing time, space, existence, and essence. Musashi's zero is a skill that arrives at a single correct answer amongst many possibilities; a sword that brings out an inescape end, even against gods and Buddha. Sasaski's infinity is a skill that creates and accepts many possibilities; a sword that creates an unavoidble future for even gods and Buddha. Musashi and Sasaki eventually reach the Realm of Infinity, also know as the Realm of Nothingness. There is no time, no space, no fate, no good, and no evil within this realm. It is devoid of thought or feeling; a place only true masters of the sword can reach. It is not a world; it is neither the proper history nor culled history; it is beyond even the rift of reality and dreams. It is an impossible domanin where zero and infinity clash endlessly. Musashi and Sasaki would duel each forever if not for Ritsuka determining Musashi as the winner. Satisfied by their duel, Sasaki escapes from the castle. Though she is the victor, Musashi recognizes she is too weak now to escape. She then throws Ritsuka out of the escape to show her thanks for them staying by her throughout her journey. They are caught just in time by Kotarou. Musashi is satisified she reached the Void, feeling there is nothing left for her. She passes away amongst the flames, wishing she was watching the clear blue sky.

Later, Sasaski meets the dying old male Musashi inside a cave, where the latter was wating for the former. The two compliment each other's swordsmanship while downplaying their own. Though Musashi will die alone, stories of his life will spread well after his death. Sasaki howver will be forgotten after he dies. Musashi refutes this though, believing Sasaki is worthy of being his rival. He regrets their duel will be unrealized, but Sasaski reveals he fought another Musashi moments ago. He witnessed that she had reached the Void of the Niten Ichiryu style. Musashi then passes away with satisfaction upon hearing this. Sasaki bid farewell to both Musashis, grateful they had the chance to meet, even though they weren't meant to.

At Toke Castle town, Kiyohime thanks Ritsuka for saving everyone. She says the castle will be rebuilt after the town is taken care of. After Otama asks them where Musashi and Muramasa are, Ritsuka goes to their room in her inn. They ask Kotarou if Murasama's Spirit Origin will be registered in Chaldea, but Kotarou doubts since this Shimosa exists in the rift between reality and dreams. He continues nothing that happens in this Shimosa can ever affect the proper history. Ritsuka realizes from this that they can return this particular Shimosa ever again. Kotarou tells Onui and Tasuke they can either stay in town, where they rely on Kiyohime or Otama when they need it, or they can return to Muramasa's hermitage. Onui decides with the former, and expresses her dream to grow up to be like Musashi. Later, Ritsuka digs through the wreckage of Toke Castle and finds the tsuba Musashi used as an eyepatch.

Meanwhile, Caster is revealed to be still be alive. He frustrated that Ritsuka and Musashi were able to stop his plan to destroy Shimosa. His True Name is then revealed to Ashiya Douman, Seimei's nemesis who tried to overthrow the government with. While he failed to invade Chaldea, Douman was able to find information on the lost history (Missing Belt). He reveals this Shimosa is similiar to a parallel world without being one; it is part of human history without being part of it; It is a world observed by the god of a distant star; a world resembling a Singularity yet isn't. Douman then reveals Satan was a temporary name for his master as a joke. Their name isn't revealed though, for it is a great curse upon the world.

Ritsuka recovers from their coma. Mash tells him Kotarou arrived sooner than they hid and gave the full details about what happened. Da Vinci says Chaldea's library doesn't have any records of what occured, so she will make it herself. She continues they also need to find the true idenity of Satan that the Swordmasters mentioned, unsure whether or not it is the real Satan. She also finds Ritsuka's experience to be valvuable, saying she will throughouly debrief them later. Ritsuka is then visited by Shuten, Raikou, Kiyohime, Tamamo. On their way to their room, they encounter Edmond. They recognize him as the Missionary they met in Shimosa, but he denies it. He then tells them to check their desk before sleeping. There they find a prerecorded video messange from Musashi. She first off by saying Edmond told her to record it before she continues her journey. She reveals she died, but she later woke up to see a blue sky. From there she crossed many worlds until she arrived outside of Chaldea, where she encountered Edmond. She explains Sherlock told her she is a now Heroic Spirits who materialized outside Chaldea thanks to a Chaldea summoning spell. Thanks to her connection with Ritsuka, her Spirit Origin was recorded as a Heroic Spirit after she died. Sherlock also told her she is now a Servant who automatically forged a contract with Ritsuka as her Master. He found it strange though that a "what if" Heroic Spirit who shouldn't exist could be summoned. Musashi ends the recording hoping to see Ritsuka again someday, addressing them as Master.
