The events of Chaldea's visit to this Singularity are covered in an event of Cosmos of the Lostbelt; , referring to the fifth collaboration between Fate/Grand Order and Fate/KOHA-ACE.
==Setting==
Seeking revenge against Himiko for preventing his conquest, Kukochihiko sought to plunge her country into darkness. As the first step, he killed Iyo, knowing the country would decline without an heir. He then used his powers to seperate Yamatai-koku from the rest of the world. Afterwards, he summoned Serizawa Kamo with the Holy Grail. Knowing the former Shinsemgumi commander greatly resented towards his former unit, Kukochihiko gave him his powers. He then remained hidden after telling Serizawa to gather the people's resentment so the old gods may be revived. With his newfound powers, Serizawa began corrupting both the land and its people. Sunlight became weaker, water was polluted, and rice grew poorly. Meanwhile, the people were driven insane by the darkness, and began attacking their friends and neighbors. Serizawa also forcibly corrupted the people to creae his owm Shinsemgumi, the Dark Shinsemgumi. The Dark Shinsemgumi ravaged the villagers, stealing their reserves, and collected their resentment for the purpose of reviving the old gods. Serizawa also summoned Yamanami Keisuke and Saito Hajime to help him, collecting the resentment gathered as darkness from the temples. Keisuke agreed to help out of regret for being part of the team that assassinated the former commander. Saito agreed to help for the chance to duel Okita Souji.
Foreseeing what would happen to Yamatai-koku after Iyo's death, Himiko's soul summoned her Heroic Spirit self. She then used her mirror to connect the Singularity with the future, making contact with Chaldea. Ritsuka and a number of their Servants were then transported to the Singularity. Among the Servamts was Nobunga Oda, who arrived before everyone else. She was forcibly made into a fake Iyo to rule Yamatai-koku forvever, and to gather emnity from the faithless. In truth, she was asked to take the role by Iyo's soul, and to bide her time until Himiko's return. In accordance with this request, Nobunaga trapped various Servants in haniwa resembling Nobbu to protect the temples so the Dark Shinsemgumi could't collect the darkness gathered there.

=== Part 1 ===
At Chaldea, Oda Nobukatsu shows Ritsuka, Mash, Oda Nobunaga, Okita Souji, Leonardo da Vinci, and Nagao Kagetora a haniwa shaped like a Nobbu. It suddenly starts glowing, and proclaims that Yamatai-koku will be destroyed in October 2020. It then transports the group to Yamatai-Koku.Fate/Grand Order - GUDAGUDA Yamatai-Koku, Prologue: The Haniwa Beyond The Light
While being transported, the voice of a priestess tells Ritsuka that she was searching for the strongest person to save her country from destruction. She congratulates them for being chosen, and asks if they have supernatural powers. Ritsuka replies they do not, but guesses their Servants might. The priestess then decides to connect her mirror to Ritsuka's world, though there is the possibility their body and soul will be dissipated. Ritsuka are then fully transported.Fate/Grand Order - GUDAGUDA Yamatai-Koku, Act 1: From a Far Away Future
Ritsuka wakes up on a beach with a girl and a talking turtle. The girl knows Ritsuka comes from Chaldea in the far future, even knowing their names. She then introduces herself as Himiko and the talking turtle as her brother. She then welcomes Ritsuka to Yamatai-Koku. The three move near a village when they notice fighting coming from there. They arrive there to find Mash and Nobukatsu evacuating the villagers whose village are being attacked by the Dark Shinsemgumi. They prove too numerous for the group to overcome though. A man suddenly appears and kills a number of Dark Shinsemgumi. He is then directed by a man wearing glasses to help the group. After the battle is won, the two men introduce themselves as Yamanami Keisuke and Saito Hajime. 
Inside a village hut, a woman explains the country was ruled peacefully by Queen Iyo until she was swallowed by the "Evil Darkness". From there, the country became isolated from the rest of the world, sunlight weakened, water became contaminated, and rice has grown poorly. Consumed by darkness, the villagers became insane and attacked their friends. The Dark Shinsemgumi are also ravaging villagers, and stealing their reserves. Mash assumes Yamatai-Koku has become a Singularity since the country is now an evil kingdom under Iyo's rule. The woman reveals the darkness flowing from the village temple, which being protected by animated haniwa. She then leads them to the temple.
At the temple, the group find the haniwa is the same one from Chaldea. The woman explains darkness has flowed from the temple ever since the Nobbu haniwa appeared. The group try to destroy it, but it proves too hard from them to break. Himiko empowers herself and destroys the haniwa to reveal Okita was trapped inside. With the haniwa destroyed the darkness flowing from the temple dissipates. The group then return to the village. They decide to rebuild the villages, destroy the remaining haniwa, and deal with the Dark Shinsemgumi.
With Nobukatsu's instructions, the group improve the village's water flow. Keisuke tells Ritsuka, Mash, and Nobukatsu that Saito located the next temple and haniwa. Retrieving Himiko, the group gather together and learn the temple has a dragon living in it. They proceed to the temple to find Oryou in her true form trying to destroy one of the two haniwa.

The next day, the group learn the next temple is protected by a haniwa that commands other haniwa. They enter a forest where a haniwa flees from them, but they don't give chase as Keisuke suspects it was a decoy. He then directs Saito and Okita to flank from the right and left side respectively, and for Okada to serve as bait. The plan is successful, leaving only a few haniwa and the shining haniwa that commands them. The group destroy them, revealing Kagetora was trapped in the shining haniwa.Fate/Grand Order - GUDAGUDA Yamatai-Koku, Act 3: Farewell, As You Get Swept by the Wave of the New Era Meanwhile at Chaldea, Chacha, Mori Nagayoshi, Okita Souji Alter, Li Shuwen and Mysterious Heroine X rayshift into the Singularity to rescue Ritsuka and the others.Fate/Grand Order - GUDAGUDA Yamatai-Koku, Act 4: Traceless Fallen Mountain Cherry

Meanwhile, the villagers that Nobukatsu gathered are corrupted by supposedly Nobunaga. She proclaims to be Iyo though after the Himiko's brother prevents her from killing Nobukatsu. Afterwards, she leaves with Serizawa and the Dark Shinsemgumi. The group decide to investigate the connection between Serizawa and "Iyo", and why Nobunaga pretending to be "Iyo".
The next day, Himiko guesses Serizawa and "Iyo" are based in the temple she was in. Unfortunately, the darkness surrounding the temple is too dense for Himiko to remove in her current state. Saito and Keisuke leave to investigate the haniwa. The next day, Saito tells the group that he found the next temple. Keisuke explains it is guarded by a single Haniwa deep within the forest. Kagetora stays behind with Nobukatsu and Himiko's brother to train the village in combat while the rest proceed to the temple. They arrive there to find the haniwa forcing the Dark Shinsemgumi to retreat. They destroy it to reveal Hijikata Toshizou was trapped inside.

Serizawa reveals the fake Iyo was created to rule Yamamatai-koku forever because the real Iyo didn't have an heir apparent when she died. He then declares he was summoned by those who lost their lives under Himiko's rule to destroy and rebuild the country. He reveals he made Nobunaga into the fake Iyo to gather enmity from the faithless. With enough darkness gathered thanks to the group, Serizawa forces them to fight Nobunaga. He, Keisuke, and Saito then leave. The group defeat Nobunaga and return her to her old self. She reveals she asked to be the fake Iyo by the real one's soul, and bide her time until Himiko returns. Unfortunately, Serizawa used the Holy Grail to control her. Nobunaga reveals the Dark Shinsemgumi were gathering the country's resentments to revive the old gods. She disappears, and giant Nobbu haniwa appear all over the country. Their particular shape is suspected to be a result of the darkness connecting to Nobunaga's consciousness.Fate/Grand Order - GUDAGUDA Yamatai-Koku, Act 7: Doomsday by a Impetuous Deity
The group return to the village. Ryoma explains the giant haniwa are coming towards them, destroying many settlements as a result. Himiko suspects they're masses of resentment, revealing there is spell to control them under the name of evil spirits. Ryoma says there are seven in total, but he warns they'll regenerate unless cut off from the source of their resentment. Nobukatsu tasks Ryoma and Okada with locating Serizawa. He then orders Kagetora to give him commands of the militia she trained for the purpose of building fortifications. He then tasks the others with destroying the gaint haniwa to stall for time so he can find their weakness. He orders the villagers to gather food for preparation for war, but they refuse to listen him. They decide to flee when Himiko arrives and convinces them to listen to Nobukatsu. The group then leave to fight the giant haniwa.
While the group continue fending off the giant haniwa, X arrives in the village and destroys the giant haniwa nearing the village. Meanwhile, Chacha, Mori, Li Shuwen, and Okita Alter are also helping the group against the giant haniwa.

She realizes Saito didn't want her to kill Keisuke again, though he denies it. She then passes through after praising Saito's sword skills.
The group confront Serizawa, who reveals the Dark Shinsemgumi are the people of Yamatai-Koku forcibly transformed by the darkness. He then orders Keisuke to command the Dark Shinsemgumi to kill the group. After the group defeat them, Serizawa further inflicts the Dark Shinsemgumi squad leader with the curse of resentment. The curse itself is a collection of grudges that grants power equal to the amount of resentment. Mash realizes he wants them to kill them and increase their resentment. The curse then transforms the squad leader into Inugami. The group fail to destroy it though, as its resentment keeps regenerating it. Nobukatsu stabs Serizawa in the back, but the latter is unaffected. Serizawa tries to kill him, but Himiko's brother protects him at the cost of his own life. But before he dies, he grants his power to Nobukatsu, increasing the power of his Spirit Origin. He then resurrects Nobunaga.

Kukochihiko was a sorcerer in service of the Dog Kingdom, who usurped the throne and tried to conquer Yamatai-koku. He then traps everyone in the cave of everlasting darkness that nurtured countless grudges since the Age of Gods. To his shock though, Himiko appears, revealing herself to be the one who asked Ritsuka to save Yamatai-koku. Kukochihiko realizes she was the one who summoned Himiko into the Singularity, having foreseen the dangers the country would face after Iyo's death. Himiko then appears and fuses with her other self, dispelling the darkness surrounding everyone. The group defeat him, and Himiko purges him. Everyone is then transported back to Serizawa's base when the realm begins to collapse. They all leave except for Hijikata, who sensed Serizawa was still alive. Okita and Saito then arrive to help him fight their former commander. They all mortally wound him, dispelling Kukochihiko's remaining power from him. Keisuke is shown to be still alive, revealing a small fragment of Kukochihiko still exists. A vortex of darkness then opens up beneath Keisuke and Serizawa. Keisuke tries to drag Serizawa into the vortex with him, but Saito pushes him out of it. Serizawa then disappears into darkness, still refusing to accept the Shinsemgumi that succeeded him. Keisuke dies of his wounds soon afterwards.Fate/Grand Order - GUDAGUDA Yamatai-Koku, Final Act: In Between Light and Darkness
