Rin remained wary of the added Master but accepted Chaldea’s assurance that their alliance would continue and that they would support her victory.

In a Lostbelt where the Ming Empire had moved its people to the Moon Sea, Sakura learned from Rider that Earth might have been lost and that the lunar relocation had prepared the nation for this crisis. Meanwhile, Gu Mo questioned how the Lostbelt’s history had come into being, suspecting its entire world line had been created only five minutes earlier.

• The Ming Empire defeated the Qing, revived its power, and advanced through technological eras until it relocated the nation to the Moon Sea a century before the present.
• Sakura woke from a recurring dream about a loving older sister and an abandoning father, then left home for school in the Moon Sea megacity.

• Gu Mo watched Sakura and Rider from a tower and wondered whether the Lostbelt’s history and memories had been created only five minutes earlier.

Gu Mo examined the Fantasy Tree he had transplanted to the Moon and realized his newly created Lostbelt had taken shape exactly as planned. He decided to escape the tree’s restraints and cut it down before the Alien God could use it to descend, then saw that Earth had already been initialized and surrounded by Storm Walls enclosing Lostbelts.

• Gu Mo preserved a vague flash of inspiration in a memory palace because he lacked enough knowledge to understand it.
• Gu Mo inspected the giant tower and discovered that a Moon-scale Containment Device shaped the Fantasy Tree into the framework supporting the Sea of the Moon.

• Gu Mo appeared on the lunar surface and saw that Earth had been bleached white, with its civilization erased.
• Gu Mo identified the scene as the FGO Timeline, where Storm Walls enclosed Lostbelt domains after Earth’s initialization.

Gu Mo confirmed that his Lostbelt had established itself on the moon and considered using its formidable forces to retake Earth, while he could not locate Chaldea through divination. In a parallel world during the Fifth Holy Grail War, the remaining Chaldea members teleported into Tohsaka Rin’s mansion and told Fujimaru Ritsuka that the Lostbelt assault had begun.

• Gu Mo considered sending his lunar forces to reclaim Earth and regretted that he could not manifest the True Spirit Rank Chart.
• Gu Mo could not see inside Earth’s Storm Walls or locate Fujimaru Ritsuka and the others, and he inferred that they were evading pursuit through Imaginary Space.
• Chaldea’s remaining members teleported into Tohsaka Rin’s mansion in the Fifth Holy Grail War, smashing her last valuable tea set.
• Mash told Fujimaru Ritsuka that the Lostbelt assault had begun and Da Vinci explained that the surviving Chaldea staff had fled after other Servants stayed behind to cover their retreat.

Little Da Vinci explained that the Mage's Association and its allies had shut down Chaldea's magical energy supply before an unknown force erased Earth. Chaldea escaped to the Parallel World using coordinates Fujimaru Ritsuka had provided, and planned to rebuild there, but the whereabouts of Ishtar remained unclear.

• Little Da Vinci told Tohsaka Rin and Fujimaru Ritsuka that the Mage's Association and various countries had tried to dissolve or take over Chaldea after the Grand Order.

Koyanskaya entered the True Moon Sea Nation to investigate its out-of-control Lostbelt, but her attempt to charm a silver-haired woman triggered an alarm and brought the city’s superhuman police after her.

• Koyanskaya unleashed her spiritual pressure against the military wyverns and combat mechs, but the forces continued to attack her.

• Goddess Rhongomyniad appeared in the ritual array, and Gu Mo recognized her as the spiritual construct of the Holy Lance.
• Koyanskaya defeated the surrounding forces, but Heracles and an Evil Dragon wearing the True Evil Dragon Blood Armor approached to fight her.

Gu Mo’s Pseudo-Grand Servants Heracles and Siegfried confronted Koyanskaya, combining their attacks to devastate the subspace where she had caused trouble. As Gu Mo explained the disturbance to the goddess over dinner, she questioned why he still wanted to summon a true god-level being when his Servants were already so powerful.

• Gu Mo had enhanced Heracles into a Pseudo-Grand Archer by giving him an additional Spirit Origin and had selected Siegfried as a Pseudo-Grand Saber.

• Gu Mo told the goddess that a fox had sneaked into the house and that his Servants had driven it away.
• The goddess asked Gu Mo why he remained determined to summon a true god-level being despite his two powerful Servants.

• A visitor numbered NO.23 emerged from the summoning circle in Fuyuki and headed for the Einzbern castle, where the other arrivals were gathering.
• Fujimaru Ritsuka explained Lord El-Melloi II's strategy to Tohsaka Rin as Da Vinci drove the group toward the Einzbern territory to deal with the threat posed by Heracles and the girl accompanying him.

Chaldea followed Lord El-Melloi II.’s unfinished strategy and traveled to the hidden Einzbern Forest to investigate the Fifth Holy Grail War. Little Da Vinci began breaking through the forest’s concealment, while Tohsaka Rin remained troubled by the goddesses possessing her and the increasingly strange war.

• Chaldea relied on Lord El-Melloi II.’s partial plan, though its members had overlooked how much the altered Fifth Holy Grail War could differ from their expectations.
• Little Da Vinci drove the group to the Einzbern Forest, where Rin explained how the Einzbern Family had hidden its base behind magecraft and urban legends.

As Artoria attacked Astolfo, Arash intervened, and the group discovered they were surrounded while a mysterious woman ordered their extermination in the Emperor’s name.

• Little Da Vinci opened the barrier, and the group entered the pristine castle prepared for the Holy Grail War.
• Astolfo approached the group, mistook them for fellow arrivals, and confused them with talk of the Sea of the Moon and a fast-track lane.
• Tohsaka Rin urged the group to attack Astolfo, and Artoria began overpowering him before Arash shot a projectile between them.
• Little Da Vinci and Akuta Hinako sensed that the situation differed from their information and that more Servants were inside the castle.
• Gawain, Tristan, Lancelot, and many other Servants appeared, surrounding the group as a woman ordered them killed in the Emperor’s name.
• Gawain and the other knights tried to stop the order, and the woman challenged them for defying the Emperor.

Gawain tried to prevent a battle between Artoria’s group and the more than twenty Servants gathered at the Imperial Consort’s command. The Imperial Consort agreed to let the newcomers form new contracts, but Fujimaru Ritsuka objected before the arrangement was settled.

• Gawain explained that Artoria’s group had mistaken the assembled Servants for Holy Grail War opponents and asked for a chance to resolve the misunderstanding.
• Artoria struggled to understand why Gawain and Lancelot stood with the opposing faction, while they insisted their loyalty to her had not changed.
• Tohsaka Rin and Little Da Vinci realized that their preparations had led them into a confrontation with more than twenty Servants and could not explain why the Parallel World had diverged so drastically.
• The Imperial Consort accepted Gawain’s proposal to have the newcomers form new contracts and let the incident go.
• Fujimaru Ritsuka urgently interrupted, objecting to the proposed arrangement.
