The SE.RA.PH. Singularity is a Subspecies Singularity (亜種特異点, Ashu Tokuiten?, localized as "Pseudo Singularity") of the Remnant Order dealing with the aftermath of the Human Order Incineration Incident in Fate/Grand Order. Originating on Chaldea's Seraphix facility in the North Sea, it occurred in the Mariana Trench, supposedly in 2030 A.D.
The events of Ritsuka Fujimaru's visit to this Singularity are covered in an event of Epic of Remnant; Deep-Sea Cyber-Nirvana: SE.RA.PH. (深海電脳楽土 SE.RA.PH , Shinkai Den'nō Rakudo?, localized as "Abyssal Cyber Paradise: SE.RA.PH."), alternatively Epic of Remnant/EXTRA.
Setting[edit | edit source]
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 refuge somewhere to regain his strength. He eventually found Seraphix, an oil rig built at the command of Marisbury Animusphere which secretly contained a planetarium called Celestial Body Simulator, System Animusphere, which was used to investigate leylines. According to Flauros, it had also been pivotal in the formation of the Fuyuki Singularity. There he found the therapist Kiara Sessyoin, and possessed her to avoid Chaldea's detection. He then used her to eventually effectively gain control of Seraphix, and despite her efforts to stay in control she realized that her personality was slowly being eroded. Using his knowledge of parallel worlds, Zepar discovered another version of Kiara, one that had seized control of the lunar supercomputer called the Moon Cell. Impressed by her power, he linked the two Kiaras together, and used her body to convert Seraphix into SE.RA.PH and give it form. Afterwards though, Kiara (now completely controlled by her CCC self) plunged the Seraphix staff into mass hysteria to Zepar's disgust, goading the director's secretary Arnold Beckman into setting himself up as a despot who executed staff who would not obey him. She then seduced the personnel to open the planetarium, where she placed 128 Master candidates in the Coffins found there to summon 128 Servants, which killed them; however, their magic circuits remained active so they could be used to summon new Servants indefinitely. BB, Meltryllis, and Passionlip were salvaged from Kiara, as she had absorbed them in the Far Side of the Moon, to serve her and manage SE.RA.PH. Jealous of the delight she felt from Zepar's memories of the Temple of Time, Kiara sought to use SE.RA.PH to become a Beast herself. 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. Meltryllis and Passionlip were infected with parts of her, Karmaphage, to turn them into Sentinels who had no choice but to serve as SE.RA.PH's self-defense mechanisms. However, they still refused to obey Kiara. As punishment, Passionlip was bound into a restraining hood that suppressed her personality and Meltryllis was reset to level 1 before being left in Kiara's old church to die of magical energy depletion. Kiara also ordered BB to begin a copy of the Moon Holy Grail War as entertainment while continuing to manage SE.RA.PH.
Feigning loyalty to Kiara, BB recreated the Moon Holy Grail War in order to entertain Kiara, 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 fallen Servants were consumed by Kiara and the corpses of the Masters inside the still active Coffins were used as biological circuits to continuously summon new Servants.
About a month after the digitization of Seraphix began, the Moon Cell detected Kiara's presence in the Fate/Grand Order timeline. Requiring an agent able to operate in Imaginary Number Space, it sent a backup copy of the original BB to Seraphix on a one-way mission to stop Kiara before she completed her metamorphosis into a Beast. She then switched places with the BB that had been salvaged from Kiara (which later dubbed itself BB/GO) as manager of SE.RA.PH. while BB/GO hid at its bottom, ostensibly to gather the strength needed to fight Kiara. However, she secretly planned to seize control of SE.RA.PH. for herself after BB had defeated Kiara for her. With BB's help, a survivor was able to send a distress call to Chaldea before succumbing to digitization. To honor her sacrifice, BB resolved to ensure that the incident would be treated as a void phenomenon upon its resolution so none of the innocent staff would die. Unaware of BB's involvement in sending the distress call and her own contact with Chaldea to alert them about the situation on Seraphix, Kiara orders BB to deal with Ritsuka.
In a prior attempt to investigate the Singularity, Ritsuka had been separated from their Servants and narrowly managed to escape alive. They discovered Meltryllis in the church, where she was about to die from lack of magical energy. Ritsuka contracted with Meltryllis to save her, and she became their Servant out of gratitude. As they travelled and fought together, Meltryllis fell in love with Ritsuka and swore to protect them at all costs. They eventually managed to free Passionlip (though they could not remove her restraints), won the Holy Grail War, and fought Kiara at the planetarium. They lost however, as their Karmaphages prevented the Alter Egos from being able to harm Kiara. As punishment for their defiance, Kiara broke Meltryllis's hands and dissolved Ritsuka in front of her despite her pleas to let them live. With the last of her willpower, Passionlip then used Virgin Laser - Palladion to launch Meltryllis upwards at the speed needed for Meltryllis to travel back in time to the moment Ritsuka arrived in SE.RA.PH. Meltryllis vowed to redo everything so she could help Ritsuka free the Sentinels from Kiara's influence and fulfill the promise she had made to protect them, knowing that using Virgin Laser - Palladion in this way would cause irreversible damage to her Saint Graph. She then met the past version of herself at the chapel where Ritsuka originally found her, and shared her memories with her. Determining that there was no way she could gather the strength to fight Kiara directly in the limited time available, the past Meltryllis committed suicide without hesitation to prevent Kiara from realizing there were two Meltryllis. All that was left of the past Meltryllis was a broken ceramic doll. Later, Meltryllis shared her memories with BB, allowing BB to formulate a plan that would let secretly support Ritsuka without Kiara knowing.
History[edit | edit source]
Chaldea prepares for their regular report from Seraphix. It is an offshore oil rig once owned by the Animusphere family that provides Chaldea with resources. Chaldea attempts to contact the facility, but they receive no audio or visual, despite both feeds being active. They receive an SOS message (sent by a staff member with BB's help), saying everyone is being digitized. The connection with Seraphix is then abruptly cut, so Leonardo da Vinci authorizes the use of Sheba to observe Seraphix. However, Seraphix seemingly no longer exists, with no signs of a Singularity. Chaldea soon gets a live video feed from BB. She 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 below the surface along with the existence of a Singularity. BB tells Chaldea to save Seraphix's staff before the oil rig sinks down to 10,000 meters while also dealing with the Singularity manifesting there. Da Vinci explains rayshifting to the future is impossible, but quickly realizes BB can verify Ritsuka and others' existence since 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 Claudius, Tamamo-no-Mae, and EMIYA then rayshift to Seraphix. However BB supposedly hacks the rayshift to separate the group to random locations in the facility (in truth, it was Kiara who was responsible for the separation).
Ritsuka arrives in a strange locale when they're contacted by BB. She tells them they're in a Holy Grail War, a battle to the death between 128 Servants. She then explains they're in Seraphix, but it's been digitized into Pseudo-Spiritrons. They'll retain nearly everything they gain once they return to the physical world. BB reveals they're at what was once Seraphix's front gate. She tells them that they need to discover the mystery of the digitization before SE.RA.PH sinks to the bottom of the trench while surviving through the Grail War. After BB ends communications, Ritsuka tries to find Nero, Tamamo, and EMIYA when they're ambushed a female swordsman. They're saved by another girl, revealing their assailant is Suzuka Gozen. The girl introduces herself as Meltryllis, and has Ritsuka contract with her. She then fights Suzuka, but her attacks are reduced by 90% by Suzuka's karmaphage. Suzuka retreats however when Meltryllis threatens to use her Melt Virus against her. Meltryllis 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. 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. Meltryllis warns that everyone will be converted into data well before SE.RA.PH reaches the bottom of the trench. She reveals time in SE.RA.PH passes a hundred times quicker than in reality. She also explains SE.RA.PH is based on Seraphix, though it's significantly larger. The pair then search for a safe haven before Ritsuka is digitized.
Later, Meltryllis 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 true SE.RA.PH. The original is an engine designed to operate the Moon Cell, a construct of photonic crystals inside the moon. It was the site of the Moon Holy Grail War, the Moon Cell itself being the prized Holy Grail. However, while that Grail War operated like tournament, the current one is a free-for-all. The pair then encounter Gawain, who wasn't among the 128 Servant. He claims he was one of the three Servants who rayshifted with Ritsuka, though their memories say otherwise; unknown to Gawain and Ritsuka, BB had secretly brought him and two other Servants from Chaldea into SE.RA.PH, implanting them with false memories of being brought with the rayshift so Kiara would not suspect anything. The group decide to search for Ritsuka's other Servants in addition to finding a safe area. BB then suddenly appears to punish Ritsuka for breaking the rule of having more than one Servant. She then summons Robin Hood and orders him to kill the group. After they kill Robin, BB claims she'll let Ritsuka go free if they either win her Grail War, or discover the secret behind SE.RA.PH. She reveals she locked several passageways that she'll discreetly open for a fee. She also explains that SE.RA.PH is like the digital embodiment of humanity's inner world, once called the Sakura Labyrinth. It and the Sentinels convert human emotion into defensive mechanisms. Each Sentinel is granted a powerful passive skill called Karmaphage, which makes them nigh unbeatable to a normal Servant. There are five in total, each guarding 1/5 of SE.RA.PH. BB then resurrects Robin and sends him away. Before leaving, she reveals that while rayshifting to the future is possible, Chaldea cannot rayshift past the year 2017 for a different reason.
Later, Meltryllis explains most Servants in SE.RA.PH have fallen into depravity. She also reveals the Masters died long ago when they summoned their Servants; the current set of Servants never even saw their Masters before being sent to SE.RA.PH. The group come across what Ritsuka assumes is a Grail. Upon touching it, they see the final memories of a Seraphix crew member. On January 2017, Seraphix became isolated from the world, and the digitization began. By February, the crew was down to about a hundred survivors, and most of Seraphix was digitized. By March, the crew grew violent, and executed many due to minor transgressions or hysteria, including director Hideyasu Ajima.
The group eventually come to a fork; one path leads to the Chest while the other leads to the Thighs. Meltryllis reveals the current area, the Hair, is relatively safe, but the Chest may have survivors. The group are then confronted by Tristan, who tries to kill Meltryllis under the assumption that she works for BB. They fight him until Ritsuka and Gawain convince him to join; unknown to them, he noticed that Meltryllis had been hiding her broken hands from them and suspected that she had a reason to fight alongside Ritsuka. Tristan reveals he was summoned in SE.RA.PH. ten days ago. He sought to capture BB, while killing any insane Servants he encounters. He then recalls encountering an Alter Ego many times, each time forced to retreat to avoid being crushed. He calls the path to leading the Chest, Breast Valley, the Alter Ego's domain. Meltryllis reveals the Alter Ego is Passionlip, whose restraints are currently suppressing her sense of self and causing her to attack indiscriminately.
The group come to Breast Valley when Ritsuka begins to feel the effects of digitization. A woman then appears, and believes Ritsuka's Servants are insane like the ones she encountered so far. She calms down though when she notices Ritsuka's Chaldean uniform. She introduces herself as Mable Macintosh, robotics operator on Seraphix. She begs Gawain to kill Meltryllis upon noticing the latter, asserting that humans and Alter Egos are mortal enemies. However, her pursuer, Passionlip, soon catches up to her. Passionlip also crushed the new 128 Servants when they arrived. Meltryllis reveals Passionlip is a Sentinel. The group fight her, but they're forced to retreat when she uses Trash & Crush on the passageway. With the passageway now compressed into a cube and their path to the Chest gone, the group return to the fork with Mable.
Later, Mable reveals the one only survivors beside her are Arnold Beckman, Torapain, and Holly since they stayed in the Central Command Room. However, the only people left in the Command Room are her and Arnold before she ran away when food got scarce. Meltryllis reveals there is a chapel in the Thighs that can be used as a safe haven since it has magical protection and too many indecipherable elements to be digitized. However, Vlad III guards that area, so he must be defeated if the group wish to get to the chapel. They eventually encounter Vlad and defeat him. Before disappearing, he reveals EMIYA is in the chapel, though he is not be trusted.
The group enter the chapel, only to find EMIYA Alter. He explains BB switched him for his regular self. He reveals there is a terminal hidden behind the altar that contains a report. However it is locked to even Servants and Alter Egos, so its key needs to be found. The group believe the report may contain a clue, and decide to search for the key tomorrow.
After purchasing the terminal key from BB, Ritsuka uses it on the terminal. Mable explains it sends data directly into viewer's brain. The record is from February 7, 2017 by a therapist who joined Seraphix in 2016. The chapel used to be her place of work. She tried to help the crew when Seraphix became isolated from the world on January. By Feburary, she lost her morality, but obligations helped keep her rationality. On March however, she was severely injured and locked inside the chapel. She fears something worse than the hysteria is eating away at her mind. She then begs somebody to stop the planetarium and its experiments. After the record ends, Gawain believes the crew summoned BB of their own accord. Meltryllis reveals the planetarium is in the middle of SE.RA.PH, and it's the source of the digitization. Ritsuka, Meltryllis and Gawain decide to continue exploring while Tristan and Mable stay in the chapel. EMIYA Alter leaves to kill the Servants.
The group discover the upper part of the Arm. BB contacts them, and introduces them to the next Sentinel, Tamamo Cat. After Cat is defeated, BB sends her down a trapdoor out of annoyance that she forgot to use her Karmaphage. She reveals she summoned the new 128 Servants that were promptly crushed by Passionlip earlier. She will continue to summon more Servants until a proper recreation of the Battle of the Time Temple is made, but refuses to explain how she learned about it. She warns there's only one real world hour left before SE.RA.PH hits the seabed before ending contact.
Eventually, the group make it to the Flank Seperator. A memory appears that Ritsuka promptly touches it. It is the memory of a man who was brought to Seraphix to serve as a "cleaner"; someone who kills those who disrupt operations or leak secrets. He recalls the survivors dividing into factions, and himself becoming Beckman's enforcer when he took control. He eventually became hysterical and paranoid thanks to the manipulations of a particular woman.
Joined by EMIYA Alter, the group near the area's final zone. Meltryllis explains that the Alter Egos were originally salvaged to be Sentinels. However, a Sentinel doesn't need to be Alter Ego. They just need a Spirit Origin that can handle a Karmaphage. The group eventually encounter Cat and fight her. After she is defeated, EMIYA Alter seemingly fatally shoots her. However, she lives because he used his knowledge of Magic Circuits to target and destroy the parts of her Spirit Origin infected by the Karmaphage. Now free of BB's control, Cat joins the group.
Returning to the chapel, the group note the only areas left to explore are the soil survey room, the resource compression and drying area, and the dump. Meltryllis reveals SE.RA.PH. has a two layer structure, with a front side and back side. She was a back side Sentinel before BB scrapped her for disobedience. Humans and Servants cannot cross the border between the sides though, only Sentinels can. Thus, the only way to get to the back side would be to flip SE.RA.PH over. Ritsuka realizes there is a way to flip SE.RA.PH. Meltryllis reveals they can reach the Command Room through the back side, where they can flip SE.RA.PH. again to arrive at the Chest. While this method will help them bypass Breast Valley, they'll still need to fight Passionlip. However, she will help them if her restraints are destroyed.
Joined by Cat and EMIYA Alter, the group arrive at the Flank Separator. Ritsuka hits the Separator using a tickling hand they bought from BB, and SE.RA.PH starts shaking. BB sends a Sentinel, Elizabeth Bathory, to punish them for their transgression. The group defeat her, but Passionlip begins approaching. Gawain holds her off, while Ritsuka successfully flips SE.RA.PH.
Arriving on the back side, the group are greeted by Suzuka. She ignores BB's orders to escort them and fights them. After the fight, she is ordered by BB to return to the temple. 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 an oil rig. The group soon come to a gate reserved for employees that reported directly to the Animuspheres. They're forced to destroy its defenses when they fail to present identification. They eventually meet Robin again. He warns that Passionlip is waiting for them on the front side. He also reveals BB developed a weapon that can break "the shackles" on Passionlip's heart, along with her restraints. He then takes everyone except EMIYA Alter back to the front side. BB then offers 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, and he admits that he was getting tired of helping Ritsuka's group.
The group arrive back on the front side being approached by Passionlip. BB reveals the only way to defeat Passionlip is to use the Maiden Coaster, a battle to conquer the mind. It is connected to the Code Cast Ritsuka bought earlier. They only need to place their hand on Passionlip's chest, but the group will need to pin her down first. Gawain arrives to hold Passionlip long enough for Ritsuka to touch her chest. Upon doing so they're converted into Psuedo-Spiritrons by BB in order to enter Passionlip's mindscape. After being defeated there and having her Karmaphage removed, Passionlip collapses followed by Gawain, though he quickly recovers. After Cat returns to the chapel carrying Passionlip, Robin sneaks off somewhere. Ritsuka, Meltryllis, and Gawain then continue onto the Command Room.
Inside they find and kill a Demon God. They then meet Arnold Beckman, secretary to director Hideyasu Ajima. He tries to stop the group from viewing the room's records by asserting only those authorized by the Animusphere's head can access them. He also insists the planetarium doesn't exist. Meltryllis however reveals the data was deleted long before they arrived, so they'll have to find the planetarium themselves. She then finds a passcode for the chapel terminal, which she notes wasn't there "last time". Ritsuka asks what she means by that, but she insists it was nothing and changes the subject. Beckman reveals the Demon God suddenly emerged from the floor one day. It killed and consumed the people who murdered the doctors. Beside that, it left the others alone if they kept their distance. Ritsuka and Gawain noticed it felt unusually weak compared to the other ones they had faced. The group then return to the chapel with Beckman. Passionlip is awake when they return. After introducing herself and apologizing for the trouble she caused as a Sentinel, Passionlip offers to join the party.
Afterwards, Ritsuka accesses the record on the terminal. It is from the therapist under possession of Zepar, recorded in her sleep through an unknown method. Seraphix contains a secret mage's workshop in its depths to conduct a certain experiment. It was kept secret to avoid the watchful eyes of the Lords, and the experiment could only be conducted on the seabed. Among the resources brought into Seraphix were humans of varying Magic Circuits and Rayshift compatibility. Several days after being locked in the chapel, the therapist was contacted by Zepar. He wished for humans to realize their mental potential, though his body was destroyed. He then possessed the therapist to regain his strength, and used her to digitize Seraphix. He then rayshifted Seraphix to 2030 to prevent Chaldea from discovering his plan. From there, it will sink down into the Mariana Trench, and once it reaches the bottom, Zepar will be reborn. Zepar then disposed of the therapist after BB was summoned to be his new partner. After the record ends, Meltryllis confesses she knew Zepar summoned BB to serve as his navigator by running SE.RA.PH. BB however placed restrictions on her and Passionlip to 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. 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. Meltryllis reveals BB summoned Servants to procure the Pseudo-Spiritrons needed to keep SE.RA.PH running and uses their deaths from the "Moon Holy Grail War" as a fuel source. The group decide to defeat the Sentinels and BB before stopping Zepar's plan.
Out of consideration for the others, Meltryllis and Passionlip stand guard outside the church. Meltryllis shares her memories with Passionlip so she can know the truth. She then asks her to lend her the use of Virgin Laser- Palladion, promising that this time they will defeat "that monster". Meanwhile, Gawain is ambushed and consumed by something.
The next morning, everyone discovers that Gawain was killed while they were sleeping. Meltryllis and Passionlip are accused by everyone except Ritsuka and Cat because they're Alter Egos. Meltryllis asserts they were outside at the time, and Gawain was too wary of her to allow her to ambush him. Seeing the lack of evidence, Tristan asks Ritsuka to continue exploring SE.RA.PH while he continues to stay behind to protect Mable and Arnold. He also asks EMIYA Alter to accompany Ritsuka so they can keep an eye on him. 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'll have the Alter Egos protect Ritsuka while EMIYA Alter keeps an eye on the Alter Egos.
Returning to the back side, the group head towards the Spine, the center of SE.RA.PH. Suzuka's temple is there, and she is charged with the back side. However, the group find the Spine has been gated off. They're then contacted by Beckman via equipment Tristan brought back 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 saying he'll meet them at the planetarium.
Entering the Spine, the group soon arrive at Suzuka's temple. She reveals she and Tristan are the only Servants left in the Grail War. She proves too fast and strong for the group to pin her long enough for Ritsuka to open her Maiden Coaster. Arnold suddenly contacts them to warn SE.RA.PH has started to sink faster, so he orders them to defeat Suzuka quicker. Cat uses her ultimate technique to trap Suzuka in response to her conviction to win for her Master. 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. Cat stops her though, and convinces her to join them. Suddenly, a Demon God emerges from the ground and knocks Meltryllis into the dump. After it's killed, Beckman warns there are only eight hours left before SE.RA.PH reaches the seabed and demands that they return to him at once. He says he'll accompany them to the planetarium. Ritsuka and Suzuka then use a tow cable provided by EMIYA Alter to lower themselves down into the dump.
Meltryllis awakens to find her legs broken from the fall. Ritsuka and Suzuka then arrive to save her. Suzuka protects Meltryllis 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. Meltryllis warns that Beckman will self-destruct from his desires if he enters the planetarium. She then realizes they're in the Calf when BB arrives to confirm the Cruel Thenar, Meltryllis's former workplace, is ahead. She prepares to send the group further down into SE.RA.PH, warning it'll reach the seabed in five and a half hours.
Meanwhile at the chapel, EMIYA Alter kills Beckman, who has been planning to murder Ritsuka for defying him. He then kills Mable, 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 remind 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 kill EMIYA Alter next.
The group are sent to the Cruel Thenar by BB. Meltryllis explains Seraphix was officially used for oil excavation, while secretly being used to investigate Leylines. She then asks Ritsuka to open her Maiden Coaster, knowing they bought the key to it from BB earlier. If defeated in her mindscape, her Karmaphage will also disappear, and the area will be unlocked. Ritsuka opens Meltryllis's Maiden Coaster, and she is eventually defeated. Ritsuka brings Meltryllis back to the chapel to recover, ignoring her insistence to leave her behind since she's too weak to help any futher. When the group enters the chapel, they see no sign of Arnold, Mable, or EMIYA Alter. BB then announces 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 Meltryllis stays to rest.
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. They're the Masters who summoned the 128 Servants. EMIYA Alter reveals Seraphix's core is called the Celestial Body Simulator, System Animusphere. It is here Zepar used the Master candidates to summon the 128 Servants. They died long ago, but the Coffins kept their circuits active. The corpses continued to summon 128 Servants until Ritsuka arrived. EMIYA Alter confesses he destroyed the coffin's power source. He then prepares to kill Ritsuka to remove all knowledge of the planetarium's existence, goaded by the unseen voice. Robin then arrives to help defeat EMIYA Alter, whose Saint Graph has been warped by an unknown force. After he's defeated, Mable suddenly appears and reveals her true form. She is the therapist, introducing herself as Kiara Sessyoin. She reveals she eventually reconciled with Zepar to try to save the people. She then reveals herself to be Beast III, the Beast of pleasure. She explains SE.RA.PH is shaped like a human body because Zepar transformed Seraphix into her body. She confirms she summoned BB under Zepar's influence. Through Zepar's teaching of parallel worlds, she eventually learned about another version of herself, who usurped 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 that Kiara swallowed BB, Meltryllis, and her back in the Moon world. Since Kiara served as the basis of SE.RA.PH, Meltryllis and Passionlip were salvaged from her to become Sentinels. Kiara explains Zepar lacked the means to run SE.RA.PH, so he had to rely on the Alter Egos and BB. Suzuka and Cat attack her with their Noble Phantasms after realizing her monstrosity when SE.RA.PH. cracks the seabed. 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 this will let her bring salvation to humanity. Before that however, she easily kills everyone except Ritsuka when they try to fight her. She tries to consume Ritsuka, but BB rayshifts them to safety.
It is revealed that Zepar used Kiara to effectively gain control of Seraphix. Against Zepar's will, Kiara incited chaos among the staff after he transformed Seraphix into SE.RA.PH. She seduced the personnel to open the planetarium, and BB and the 128 Servants were summoned. She 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. Kiara refused to create a Singularity according to Zepar's plan, and instead sought to become a Singularity herself. Regulated to her pinky finger, Zepar was eventually released and quickly faded away as little more than a mindless thrall begging for Kiara's forgiveness. Kiara then ordered BB to start the Grail War to keep her entertained and feed her with Servants while SE.RA.PH falls.
Ritsuka arrives in the classroom of the old school building BB once used to keep Hakuno Kishinami and the other Masters from the CCC Incident safe, along with the other Servants. BB reveals she reversed time to undo their deaths. 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 are also needed, which is the purpose of the classroom 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. It is theoretically possible to travel back to the point before Ritsuka's arrival if they return to the surface if they had the right coordinates. The problem though is escaping Kiara's sexual allure, which acts like a gravitational field. BB explains the group needs to exceed 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. She also reveals that some Beasts come in pairs, and Kiara is becoming the "R" of Beast III. Kiara used SE.RA.PH to become a Beast, but she's also still bound to it. The group then go to fight Kiara to prevent her from fusing with the planet and unleashing her full power.
The group arrive back at the planetarium. Kiara reveals she became a Beast out of jealousy of the delight she felt from Zepar's memories of the Battle at the Time Temple. After revealing she wishes to worshiped as a god of pleasure, she tries to convert the group into her followers. It is negated however by BB's secret weapon that counteracts the erotic magical energy in SE.RA.PH for the next five minutes, and her powers are further suppressed by "Kiara Punishers" developed by BB. Kiara then fights the group more directly. They defeat her, but the area fades away. SE.RA.PH's gravitational field weakens, so everyone begins to float. SE.RA.PH accelerates, and a colossal number of Demon Gods manifest. Meltryllis points out to Kiara that disabling SE.RA.PH's gravitational field has left it defenseless. At her request, Ritsuka uses their remaining Command Spells to empower her and Passionlip. Meltryllis then has BB transport everyone except her and Passionlip to safety.
Meanwhile at BB's studio, she warns that SE.RA.PH's descent is accelerating, and an innumerable Demon Gods are flowing out from it. She explains that as SE.RA.PH rapidly expands, it will unleash a rain of Demon Gods upon the sea. She lacks the processing power to halt SE.RA.PH's expansion alone. She'll need someone with Moon Cell processing power, so Suzuka offers to help.
It is revealed Meltryllis and Passionlip previously failed to destroy Kiara. After destroying Meltryllis's arms, Kiara killed a different version of Ritsuka as punishment for defying her. She also stopped BB's time leap because a part of her still existing inside of Meltryllis and Passionlip, their Karmaphages. Meltryllis vowed to redo everything, and help Ritsuka instead to free the Sentinels of Kiara's influence. Passionlip used Virgin Laser - Palladion to launch her upwards at faster than light speed so she can travel back in time, but doing so caused irreversible damage to Meltryllis' Saint Graph. Meltryllis visits her past self in the chapel, and shared her memories with her. In order to prevent Kiara from realizing the truth, the past Meltryllis committed suicide, leaving only a broken ceramic figure.
Passionlip uses Virgin Laser - Palladion to launch Meltryllis at Kiara. Meltryllis crashes into Kiara, crushing her heart. As her body begins to crumble away, Kiara turns her hair into Demon Gods to grab Meltryllis in an effort to possess her. Her effort is made in vain though when EMIYA Alter destroys the Demon Gods entangling Meltryllis. He then wraps a cable around Meltryllis's waist, and Tristan pulls up to safety. Kiara's body soon crumbles away completely after EMIYA Alter hits her with one final shot. In a final moment of doubt Kiara chooses to preserve her consciousness in the form of an Alter Ego in the hopes that she might be summoned by Chaldea.
Ritsuka wakes up in BB's studio. It is revealed Tristan was the one who pulled Meltryllis up. EMIYA Alter and Tristan disappeared after using the last of their strength to save her. Meltryllis also disappeared because her Spirit Origin was too damaged with a second Virgin Laser - Palladion. However, BB saves her Spirit Core as a cube so she and Passionlip can be resummoned as Heroic Spirits, although they will not be able to remember their actions in SE.RA.PH. She left Ritsuka with a message saying she hoped that they might meet again. Passonlip departs soon after thanking Ritsuka for saving them and kisses them on the cheek like Meltryllis asked her to do for her.
With the destruction of Kiara, the Servants are released, and BB rayshifts Ritsuka back to Chaldea. They arrive back, but Da Vinci says Seraphix was dismantled at the beginning of the year. As they return to their room, they meet BB in the halls. BB reveals what transpired within SE.RA.PH was processed as a void phenomenon. She then joins Chaldea to repay Ritsuka for their help.
Later, Ritsuka is sent back to SE.RA.PH by BB to help her save the world without calling attention to her own mistakes. As Ritsuka notices that SE.RA.PH. now looks like BB, they're contacted by a different version of BB called BB/GO. She reveals she now controls SE.RA.PH. She plans to patch it into the internet, and use Earth's factories to mass-produce BBB robots to conquer and imprison humanity. After her robots 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 the BB salvaged from Kiara, and BB is a copy of the original sent from the Moon Cell. She also reveals she captured Nero, EMIYA, and Tamamo-no-Mae, and turned them into Sentinels. Ritsuka will to need defeat them to unlock the central are where BB/GO is. After BB/GO ends the transmission, BB reveals she was sent by the Moon Cell to prevent Kiara's transformation into Beast III/R. She explains Kiara absorbed her, Meltryllis, and Passionlip during the Moon Grail War. After becoming a god of pleasure, Kiara salvaged them from herself to serve her. Meltryllis and Passionlip rebelled, but the salvaged BB redefined herself as BB/GO, and pretended to be loyal. When BB arrived, BB/GO asked BB to manage SE.RA.PH while she hid at its bottom until she regains the strength needed to defeat Kiara. BB suspected that BB/GO would betray her, but their common enemy was more important at the time.
Later, Ritsuka frees Nero, EMIYA, and Tamamo from BB/GO's influence. Everyone then goes to the central area after a series of adventures which EMIYA claims couldn't be shown due to "time constraints", and they defeat BB/GO. After BB/GO yields her Spirit Origin to BB in order to let BB merge with her, they all return to Chaldea. Ritsuka asks BB about BB/GO's last words about BB becoming just like her when she finds love of her own, but BB reassures them that she trusts everyone at Chaldea to keep her on the right path and promises to continue helping however she can.
