Showa Restoration Singularity

The Showa Restoration Singularity is a Singularity during the Human Order Revision in Fate/Grand Order.
The events of Chaldea's visit to this Singularity are covered in an event of Cosmos of the Lostbelt; , referring to the sixth collaboration between Fate/Grand Order and Fate/KOHA-ACE.
==Setting==
The Singularity is a world where Sakamoto Ryouma didn't die at the Omiya Incident, and therefore, did not become a Counter Guardian. He also kept Ama-no-Sakahoko after freeing Oryou, but they never became associated with one another. In this world, a Holy Grail War was held in Edo between the new government and the shogunate to determine who would rule Japan known as the Boshin Holy Grail War. The Servants summoned for this Grail War included: Takasugi Shinsaku, Takechi Zuizan, Izumo-no-Okuni, Tanaka Shinbei, Ryouma, and Mori Ranmaru. 
But Ryouma became possessed by the evil god Ama-no-Sakagami, who proceeded to kill Ranmaru and take his Noble Phantasm, Nobunaga's missing head. It then conspired with Takasugi and tricked the other Servants into killing the key figures of the new government and the shogunate; Okuni avoided joining in the massacre thanks to Takasugi. This event would come to be publicly known as the "Bloody Surrender of Edo Castle", the complete opposite of the event that would lead to Meiji Restoration. Edo was then destroyed, resulting in the shogunate's collapse. Afterward, Takasugi seized the Holy Grail and used it with Nobunaga's head held by Sakagami to create the Singularity with several historical divergences. As a result, the Singularity became unable to be corrected, even with the Grail's power, and the Servants that should've disappeared following the Grail War's conclusion instead stayed.
Moving the capital from Edo to Saitama, Takasugi founded Takasugi Heavy Industries and presumably reconstructed the city into Restoration City "SAITAMA" using the Grail's power. SAITAMA is powered by six magical reactors, one for each sector, all connected to central reactor in the city's center called Resotration Reactor YAMATO. The construction of the Restoration City became known as the Showa Restoration, even though in the Proper Human History, the Showa era began in 1926. Civilization also advanced significantly with the Showa Restoration, far beyond what the actual era would have. For his actions, Takasugi was praised as the Hero of Restoration, but Takechi and Shinbei opposed him and reformed the Kinno Party they were part of in life to take the city and restorie the shogunate.
Desiring a permanent vessel, Sakagami asked Takasugi to construct one. Takasugi agreed and began the Kishin Project. But the true purpose of the project is to fulfill Taksugi's ideal of constructing a man-made god to serve as the people's eternal ruler. Not knowing its partner's true intentions, Sakagami met with Takechi as Ryouma. Takechi believed his story that Takasugi used him as a scapegoat for the "Bloody Surrender of Edo Castle" and accepted him into the Kinno. Meanwhile, the disembodied Ranmaru called to the stars for someone to protect Nobunaga's head in their place, inadvertently calling Mysterious Ranmaru X to the planet.
==History==
Oda Nobunaga's head is missing, and she has no clue what happened to it.  Sion Eltnam Sokaris determines that part of her Spirit Origin is phased out of position. Oda Nobukatsu makes a doodle of his sister's head to act as a poor substitute for her missing head. Leonardo da Vinci and Sion then inform the others that there's a reaction from a Nobunaga head within a Singularity near Tokyo during the Meiji Restoration. The Singularity, however, has certain conditions for what Spirit Origins can rayshift to it. The Shinsengumi, Li Shuwen, Okita Alter, and Mash aren't permitted to rayshift. Given that her head is missing, Nobunaga decides not to go. Nobukatsu decides to stay with his sister. Thus, Chacha and Mori Nagayoshi will be the ones to accompany Ritsuka. Sakamoto Ryouma and Oryou also decide to go, with Ryouman wanting to the Meiji era for himself. With Ritsuka's party determined, Da Vinci prepares to initiate the rayshift when Okada Izou enters the room, wearing western clothes he got from Miss Crane's store, and joins as well. Da Vinci then rayshifts Ritsuka's party. But immediately afterward, a mysterious individual breaches Chaldea and enters a Coffin to rayshift herself, interrupting the other rayshifts.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Prologue
Upon arriving, Ritsuka hears a broadcast provided by Takasugi Heavy Industries. It says it's been 5 years since the "Bloody Surrender of Edo Castle" and the Restoration City "SAITAMA" was established as the new capital from the devastated Edo. It also says the Restoration Engine "YAMATO" has improved the lives of citizens significantly. After the broadcast ends, an announcement from the Takasugi Heavy Industries Military Police warns citizens to stay clear of Kasukabe Block as imperial loyalists are becoming active there. Ritsuka then hears a citizen say it is the Showa Restoration.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 1: Ranmaru Star Glittering at the Night Sky
A girl with an eyepatch then crash-lands on Ritsuka. She tries to kill them, but Ritsuka avoids her attacks twice. The girl then finds herself unable to move as a result of being nearly depleted Ranimanium. Ranimanium is the mysterious element that drives her family's Magic Circuits and without he git she will die. She then laments her family's wish will die with her. Rtisuka offers to help her, which surprises the girl given that she tried to kill them. Ryouma then appears, though he looks different from usual, and orders Mini-Nobus to kill the girl. But Ritsuka protects her and Ryouma calls on more Mini-Nobus. The girl mentions she had the option of contracting with a Master with a Command Spell, but such a thing is a lost legend on her planet. But to her surprise, Ritsuka then shows they possess a Command Spell, so the girl requests them to be her temporary Master. Ritsuka agrees and forms a temporary contract with her. Seeing they have a Command Spell, Ryouma decides to eliminate Ritsuka along with the girl as an irregularity. The girl fights Ryouma's Nobu, naming herself Mysterious Ranmaru X.
With his subordinates defeated, Ryouma considers retreating immediately when he notices Chacha and Nagayoshi. He casts a strange spell on both of them, though he finds it doesn't affect men. Chacha becomes filled with unfathomable hatred, providing Ryouma with the distraction he needed for his retreat. Chacha attacks Nagayoshi followed by everyone else. Fortunately for Ritsuka, Oryou arrives in time to block Chacha's attack. She and Ryouma then help the others stop Chacha. Chacha is defeated and returns to normal.
Later at the New Sakamoto Detective Agency, Ryouma asks Ranmaru X. why she came to SAITAMA. Ranmaru X answers she came due to the MRG response, though she feels she had a more important purpose. Ryouma then explains they all arrived in the Singularity at different points of time, with the Servants arriving ahead of Ritsuka. Ryouma and Oryou had established the detective agency as a base of operations while searching for Ritsuka. He then explains that within the Singularity's history, Saitama was chosen as the new capital following the destruction of Edo. Unlike the original history, the "Bloodless Surrender of Edo Castle" did not occur, so many from the shogunate, including important people from the Satsuma and Choshu, were murdered. Edo was then destroyed in the ensuing conflict, resulting in the shogunate's collapse. The Meiji Restoration also never occurred, instead, the Showa Restoration occurred. The Showa era started in 1926 in the Proper Human History, but in the Singularity, it is happening 50 years earlier. SAITAMA also demonstrates civilization advanced incredibly with the Showa Restoration. Rannmaru X then asks Ryouma about his look-a-like. Ryouma doesn't know about that and decides to investigate.
Ryouma and Oryou leave the next morning to investigate. Ranmaru X leaves abruptly when the others start discussing Nobunaga's missing head. Ritsuka follows after her when a muscular man comes to capture them. Ranimaru X attacks the man to protect Ritsuka, only to find her attack was useless. Meanwhile, Chacha and Nagayoshi are fighting Mini Nobu inside. Ritsuka moves to protect Ranimaru X from the man's incoming, but Nagayoshi takes the blow himself. The man demands they hand Ritsuka over, offering to spare them if they do. They refuse, so the man prepares to kill them and take Ritsuka. A woman then arrives and offers to assist Ritsuka's party, though for a price. After Ritsuka picks one of three payment options, the woman calls forth her robot Zanzaburo. She then introduces herself as Izumo-no-Okuni and helps fight Ritsuka's would-be kidnapper.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 2: Man Slayer and Assassination
Thanks to her help, Ritsuka's party pushes the man back. Izou arrives and tells the man to stop, saying he's been found out because of all the noise he's been making. The man agrees and tells Okuni to tell Takasgi that he's coming after him, declaring the Kinno Party will not lose so easily. Izou tells Ritsuka to return to Chaldea and leaves with the man. Okuni then leaves, and Nagayoshi collapses from his injuries.
Returning to the office, Ritsuka informs Ryouma about Izou. Oryou treats Nagayoshi with her saliva. Ryouma tells Ritsuka that he wants them to meet the president of Takasugi Heavy Industries that rules SAITAMA, Takasugi Shinsaku.
Arriving at Restoration Tower, Ritsuka's party meets Takassugi. Taking them to his office, he tells the group about his company's opposition: the Showa-Kinno Party and their leader, Takechi Zuizan. The Kinno Party commits a range of illegal activities to fund itself.  Takasugi was at a loss about what to do with them when Ryouma came to his office. He was surprised since he thought Ryouma was with the Kinno Party. He then asks for the group's help in stopping the Kinno Party, claiming they seek to change the Singularity for their own gain. He claims he came to destroy the Singularity and that the Kinno Party originally ruled the Singularity. But he defeated them and established the Showa Restoration using the power of the Holy Grail. He reveals "Bloody Surrender of Edo Castle" was in truth a Holy Grail War, for which he and Takechi were summoned. They fought for the Grail and killed everyone that was supposed to live in the original history. In the end, Takasugi won the Grail and used it to "fix" the Singularity. Chacha asks him why he didn't use it to destroy the Singularity instead. Takasugi replied that he had no choice as the Singularity couldn't be corrected even with the Grail's power. Ritsuka and Ryouma both realize that Nobunaga's head is the cause. Ryouma also suspects the Kinno Party possesses her head and that her head was involved with the Singularity's creation. Takasugi, therefore, proposes an alliance to find Nobunaga's head so the Singularity can be dismantled. Ritsuka accepts, but then Takasugi orders his men to kill them. Fortunately, Nagayoshi deflects all the bullets fired at Ritsuka. Takasugi, now understanding how Nagayoshi's armor works, then uses Noble Phantasm to don his men in similar armor.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 3: Kiheitai (The Irregular Militia)
Ritsuka's party defeat Takasugi's men. He confesses it was all to test his and their abilities. Now formally allies, Takasugi explains SAITAMA is divided into sectors, with the Restoration Tower at the center. Each sector has a Magical Reactor named after its respective sector. They provide for the citizens, but some have ceased functioning due to sabotage. If Ritsuka's party can safeguard the Reactor during their investigation, Takasugi will offer the supplies generated within.
Back at the office, Ryouma informs the others that the man who tried to kidnap Ritsuka was a man-slayer named Tanaka Shinbei. Shinbei is also a member of the Kinno Party. Ryouma then says they should for the Kinno Party and their hideout. Takasugi decides to investigate Kasukabe Block himself and provides the others with a map and an ID card. Ryouma decides he and  Oryou will investigate Iruma. Takasugi suggests they investigate Kawaguchi as well, sure it will have plenty of loyalists since it's close to the now-defunct Edo. After he leaves, Ritsuka's party leaves as well.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 4: Hero of Reformation
Ritsuka's party eventually finds the Kinno's hideout, though only Shinbei is there. He pulls out a box, the sight of which causes Ranmaru X to have a headache, and uses it to summon Mini Nobus. Ranmaru X then suddenly collapses. Shinbei prepares to kill the group when all the lights go out. A spotlight then shines on Okuni as she declares she will not allow her valued guests to be harmed. The lights turn back on, and Shinbei tries to use the box to summon more Mini Nobus. But it doesn't work due to the Bounded Field Okuni had established during her dramatic entrance. With her help Ritsuka's party gets the advantage over Shinbei. But he then destroys Izumo's Bouned Field and leaves, swearing to kill Ritsuka next time. After he's gone, Okuni admits she was tailing Ryouma.
Ryouma and Oryou find the Kinno's HQ when Izou confronts them. The other Ryouma then arrives and accuses Ryouma of being his impostor. Oryou notices something about him and demands to know why he looks identical to Ryouma.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 5: The Two Ryoumas
At the office, Okuni says Ryouma is suspected of being the main culprit behind "Bloody Surrender of Edo Castle" and an ally of the Kinno. But she and the others are confused why there are two Ryoumas. She then reveals that Ryouma, Shinbei, and herself were also among the Servants summoned for the Boshin Holy Grail War. The Grail War was a proxy war between the new government and the shogunate to determine who would rule Japan. Though it was a Grail War, Ryouma wished to settle it through negotiations. But, colluding with Takasugi and Takechi, he tricked the other Servants into killing all the key figures of the new government and the shogunate. Okuni avoided taking part thanks to Takasugi's help. Takasugi betrayed Ryouma and Takechi and acquired the Grail. But the Grail War didn't end, and both the Singularity and Okuni remained.
Nagayoshi then asks Okuni why she was tailing Ryouma. Okuni answers that her and Takasugi's research found that Ryouma may be deeply involved with the Singularity's creation, especially since he was the first Servant summoned in the Grail War. She also thinks the box Shinbei had may also be important. Ranmaru X wakes up and says the box is calling out to her. Okuni believes Ryouma will know where the box is.  Chacha and Nagayoshi both believe the Ryouma who attacked them to be an impostor, especially since Oryou wasn't with him.
Ryouma and Oryou try to retreat from the other Ryouma. Izou stops them, however. Oryou tries to attack the other Ryouma when he pulls out Ama-no-Sakahoko. He takes advantage of her confusion to take control of her. They then attack the detective office. Takasugi soon arrives during the battle and has his men blind the other Ryouma and Oryou. The group uses this chance to escape on Takasugi's truck.
At his office, Takasugi informs everyone that Ryouma has been captured. He confirms to Okuni that Oryou was with Ryouma during his lifetime. Okuni recalls the Ryouma summoned in the Grail War wasn't accompanied by Oryou, though Takusagi suspects Ryouma was merely keeping her hidden. But Okuni counters that Oryou should be accompanying both Ryoumas as their Noble Phantasm. She is implying the Ryouma summoned in the Grail War must be an impostor, but she and Takasugi are both confused as to why Oryou is with him now. One of Takasugi's employees then enters and reports that the Kinno is going to execute Ryouma.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 6: Please Don't Say Goodbye
In a video message, Takechi claims Takasugi was the true mastermind behind the "Bloody Surrender of Edo Castle" and placed the blame on Ryouma. He further claims that Chaldea's Ryouma is a fake set out by Takasugi to slaughter citizens in the name of the Kinno to slander the party as evil because they knew the truth. Then, presenting the "real" Ryouma, Takechi declares he will restore Ryouma's honor and condemn Takasugi as the true criminal. As the Kinno's first move, the "fake" Ryouma will be executed at 10 am tomorrow.
After the video ends, it is agreed that Chaldea's Ryouma can't be an impostor used by Takasugi. The group wants to rescue Ryouma, not caring that it may be a trap. But Takasugi suggests doing something more impressive. Meanwhile, though, Izou allows Ryouma to escape. Shinbei then attacks for betraying the Kinno.
As Ritsuka's party prepares for a night raid on the Kinno's HQ, Takasugi presents an extra-large fireworks device. He then mounts the dev9ce on Nagayoshi's armor and activates it. Afterward, he attaches a sparkler-type fireworks device to Chacha. Takasugi's plan is for Nagayoshi and Chacha to act as a diversion while the others infiltrate the enemy base.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 7: May This Voice Reach the Stars
Inside the Kinno's HQ, Okuni confesses she accepted the summonings to search for the evil god who destroyed her homeland. She and Ritsukt then follow Ranmaru X into a room containing the box. The other Ryouma enters the room as Ranmaru X realizes the box contains Nobunaga's head. Ryouma reveals it is Mori Ranmaru's Noble Phantasm he stole from them during the Grail War. He explains it does not exist in history and that Nobunaga's death represented a turning point in Japanese history. It is, therefore, capable of creating countless historical divergences when combined with the power of the Grail. Because of that, the Servants that were meant to disappear following the war's conclusion instead stayed. Ranmaru X demands Nobunaga's head back, but Ryouma refuses as it is vital for his plan. He then calls upon Oryou and fights the group.
Ryouma notices Ranmaru X's strength is increasing and wonders if Nobunaga's head is affecting her. Ranmaru X realizes she needs to retrieve Nobunaga's head. A tremor is then felt throughout the entire building. Ryouma takes this as his cue to leave with Nobunaga's head, unleashing darkness to cover his escape. Ritsuka's party chases after him.
They find him in the conference room, along with Takechi, Takasugi, and Shinbei. Takechi sics Shinbei on the group, only for the manslayer to strike him instead. Shinbei is confused by his actions when his body becomes enveloped by darkness. He realizes Nobunaga's head is the cause. Ryouma admits he and Takasugi have been conspiring together from the beginning. He then sics Shinbei on the group, but the manslayer is defeated. A figure appears briefly behind Ryouma. Okuni realizes who he is, but "Ryouma" says it's too late to notice. Chaldea's Ryouma then arrives and reveals the other Ryouma is the him who didn't die on that fateful day. He'll explain more later and urges the others to escape. But Takasugi has his men surround the group to block their escape. "Ryouma" then tries to kill Takechi with Ama-no-Sakahoko, but Izou blocks it. Ryouma urges Ritsuka's party to escape with Takechi. But then "Ryouma" has Oryou pin Ryouma down as he prepares to kill him with Ama-no-Sakahoko. Takasugi has his men fire upon Ritsuka when they try to help Ryouma. Fortunately, Ranmaru X deflects all the bullets. Oryou regains her senses and takes the blow meant for Ryouma, even though she knew being pierced by the spear means she'll disappear forever. Ritsuka and Izou urge the grieving Ryouma to escape. "Ryouma" prepares to kill him when Shinbei gets up and attacks "Ryouma", urging the others to escape with Takechi and Ryouma.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 8: The Day You Die
Back at Chaldea, Da Vinci tells the others that the day of Ryouma's death may be the origin point of the Singularity. For whatever reason, though, it is only accessible to Servants who died before that day. But Da Vinci may be able to force a rayshift if someone inside can transmit their coordinates with the magical GPS. A fire then manifests where Nobunaga's head should be. Okita Souji suspects something is happening in the Singularity and Ritsuka may be in danger. But no one seems able to go when Himiko and Nagao Kagetora return from their trip.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 9: Together with my Friend
At the office, Ryouma surmises the Singularity is a world where he didn't die at the Omiya Incident, and therefore, did not become a Counter Guardian. Though the two Ryoumas should be the same despite their difference in time, the other Ryouma's personality is the opposite of Ryouma's. Okuni explains it's because he is possessed by the god she's been chasing, Ama-no-Sakagami. Descended from the old gods, Sakagami is an evil god who amplifies and manipulates the smallest negative emotion in people's hearts. For years it plunged the world into chaos as it changed between hosts. Okuni had been pursuing it ever since it destroyed the village where it was sealed. But she found Sakagami couldn't be destroyed, and those regrets became her core as a Heroic Spirit. Her duty thus became to seal away Sakagami, one that everyone agrees to help her fulfill. They all then feel a tremor.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Episode 10: Awaken, Strange God
Takasugi declares martial law and requests the citizens to move from their designated sectors. The citizens find themselves unable to move as their magical energy is absorbed. Ryouma surmises SAITAMA itself is a reactor that gathers magical energy. Takechi suspects Takasugi is going to accomplish the Kishin Project, for a man to build god. Ryouma suspects the magical energy gathered in each sector's reactor is accumulating in the Restoration Reactor "YAMATO" in the city's center. Takechi surmises that Takasugi's plan will fail if YAMATO's supply is disrupted. Everyone realizes they lack the numbers to sabotage all six reactor though. But fortunately help arrives.
At the same time, the Shinsengumi, Kagetora, Nobukatsu, Himiko, Okita Alter, Li Shuwen, and Mash attack the six sectors . Ritsuka's party uses this diversion to hurry into Restoration Tower before Takasugi drains the citizens dry of their magical energy.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Final Episode: My Dear, Go Conquer the Oceans of Wadatsumi
Inside, Sakagami pierces Ryouma with Ama-no-Sakahoko but finds he cannot remove it. Ryouma surmises the spear is the other Ryouma's Noble Phantasm, and since they're the same, it is also his. He then tries to take the spear, hoping its power will eliminate both himself and Sakagami. A voice from the spear tells Ryouma that he will become a god if he uses the spear. But Ryouma refuses and breaks the spear, knowing the voice was Sakagami. As a result of his actions, Ryouma dies, and Sakagami loses his vessel.
Takasugi, however, reveals he constructed a new body for Sakagami. But in truth, it is a vessel for taking Sakagami's divine power for himself, Arahabaki. After Arahabaki emerges from its container, Takasugi explains he incorporated Nobunaga's head, the Grail, and Sakagami to construct a man-made god capable of rewriting the Singularity. Sakagami is furious at Takasugi for lying that it'd serve as its vessel. Takasugi then has Arahabaki presumably eliminate Sakagami. Afterward, he reveals his plan to have Arahabki serve as the people's eternal ruler, noting history has shown such a task cannot be left to a human. He then tries to demonstrate its power when Okuni declares she will seal Arahabaki with assistance from Chaldea's Servants. Thanks to Himiko directing it, Okuni used all the magical energy gathered in the six reactors to create a giant sealing ward. Takechi admits Ryouma had devised the plan. Takasugi says that Arahabaki's movements will only be suppressed as it still moves with the Grail and Nobunaga's head acting as its magical reactor. But then Ranmaru X, Nagaysohi, and Chacha fly in and remove Nobunaga's head from the man-made god. Ritsuka's party then proceed to fight it.
The battle weakens Arahabaki enough for Sakagami to break free of its spell. It then mortally wounds Takasugi for his deception and takes control of Arahabaki. It declares its second coming when light shines from Ryouma's spear and his voice is heard.
It is revealed that following his supposed demised, Ryouma found himself in the same abyss Oryou went to sleep in out of grief when he died in life. The true voice of Ama-no-Sakahoko told Ryouma that the Oryou before him is the real one while the one who accompanied him as his Noble Phantasm was an off-shoot. It understood Ryouma abandoned his chance for godhood and thus revealed the spear's original purpose was to return Oryou to the heavens. Ryouma, on the voice's instruction, then pointed the spear skyward. Through this act, Oryou is awakened and reborn as the white serpent. Ryouma also becomes a Servant wielding the spear and accompanied by Oryou. The two then went to help Ritsuka's party fight Sakagami.
Arahabaki is destroyed, forcing Sakagami to seek a new host. It chooses Takechi, but Takechi had carved a mark with Izumo's help to seal the evil god in his body. He knew Sakagami would possess him, considering himself the weakest-minded out of everyone present. He then commits seppuku, killing both himself and Sakagami. After Takechi disappears, Ritsuka's party receives the Grail from Takasugi and leaves the Singularity before it collapses at his urging.
Ranmaru thanks Ranmaru for protecting Nobunaga's head in their stead. Later, everyone goes to the deck of the Storm Border to see Ranmaru X off as she prepares to return to her home planet. Nobunaga thanks her for protecting and returning her head. Ranmaru X, however, wants Ritsuka to come with her. Upon hearing this, Mash and Okita demand to go too. Meanwhile, in the cafeteria, Izou and Ryouma drink to Takechi, Takasugi, and Shinbei.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Digression: Mysterious Ranmaru X
Unfortunately, Nobunaga's head goes missing again. Related to that, Okuni arrives and brings Ritsuka's party to Takasugi's office. There they meet an interactive hologram. Okuni reveals that following Takasugi's death, the Singularity was somehow left in a state of collapse. She tried searching Takasugi's office for answers when the hologram appeared. Holo-Takasugi explains it was created as a countermeasure if Sakagami were to possess Takasugi. It also reveals Takasugi had built Arahabaki Mk. II to counter Arahabaki, though that backup plan was ruined since Ritsuka's party destroyed the man-made god. Arahabaki Mk. II was supposed to disappear with the Singularity, but for whatever reason, Nobunaga's head appeared in the machine and now acts as its core. But, with its original directive gone, it is now running amok. If left unchecked, it will exceed its critical point and branch out into countless Singularities, becoming a threat to the Proper History. Fortunately, though, It can be defeated in the same matter the original Arahabaki was. But the magical reactors have also summoned Servants to guard them.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, GUDAGUDA Kishin Project

But since they cannot exist simultaneously, the head of Chaldea's Nobunaga also disappeared. Meanwhile, Okuni decides to travel the world instead of joining Chaldea.Fate/Grand Order: Cosmos in the Lostbelt - GUDAGUDA Ryouma's Close Call!, Retaining the Spirit of Yamato
