Chapter Summaries

Rimuru reassured Marisbury about the future, then set out with him and Sylphiel to deal with Shinji Matou. They found Shinji hiding in the burned basement, but just as Rimuru moved to kill him, a silver-haired girl snatched the Seed of the Phoenix from Shinji.

• Rimuru told Marisbury that the future’s ideals had been inherited, though he did not know whether Marisbury’s plan had succeeded.

• Rimuru, Marisbury, and Sylphiel found Shinji hiding in the burned basement and attacked him when he struck first.

• A silver-haired girl appeared and took the Seed of the Phoenix from Shinji’s hand, startling both Shinji and Rimuru.

Rimuru analyzed the Seed of the Phoenix, took its Nirvana Flame, and burned Shinji Matou after hearing his final plea about Sakura. As Rimuru left, Great Sage suspected the Seed's power belonged to Phoenix, who sensed Rimuru through the flames and found the connection amusing.

• Rimuru identified the Seed of the Phoenix as concentrated Nirvana Flame and decided to absorb its power rather than become a Phoenix.
• Shinji Matou attacked Rimuru with Crest Worms to reclaim the Seed, but Rimuru incinerated the worms and judged Shinji a qualified Magician.
• Rimuru explained that the Seed would have destroyed Shinji's body and Magic Crest, then burned him while recognizing his devotion to Sakura and secretly arranging to watch over him.

Rimuru spent the night with Sylphiel, then discussed the end of the Holy Grail War and his future with Rin. He revealed that Heroic Spirit Emiya’s final wish allowed either killing Shirou Emiya or saving humanity while letting Shirou become a true ally of justice, though Shirou would first need the strength to defeat Rimuru.

• Rimuru told Rin that Shirou still had a chance to fulfill Heroic Spirit Emiya’s final wish by saving humanity and becoming an ally of justice.
• Rimuru said Shirou would need enough strength to defeat him, leaving Rin doubtful that Shirou could manage it.

Shirou Emiya questioned why he wanted to become an ally of justice, then reaffirmed his resolve to carry on Kiritsugu Emiya’s wish. Meanwhile, Rin Tohsaka resisted ending the Holy Grail War quickly, insisting she wanted to gain experience and pursue a perfect outcome.

• Fujimura Taiga stayed at the Emiya Residence, sparred with Shirou Emiya, and told Saber about Shirou’s kendo talent and Kiritsugu Emiya’s easygoing nature.

• The next morning, Rimuru urged Rin to end the Holy Grail War efficiently, but Rin insisted she wanted to gain experience and would not abandon the pursuit of a perfect outcome.

Rimuru and Rin planned a date that would also serve as a way to draw the remaining factions into action, while Rimuru considered how they might break the stalemate. At the church, Gilgamesh revealed his plan to use the Holy Grail to subject humanity to hardship, and the chapter ended with Shirou preparing to face Rimuru again.

• Rin invited Rimuru on a date and showed him a map of places where they could investigate and lure their enemies into acting.
• Rimuru reasoned that Caster might target Saber, recruit other Servants, or try to seize the Lesser Grail, and he noted that Berserker’s Noble Phantasm had a three-day recovery period.

• Gilgamesh told Kirei that he wanted the Holy Grail to bring hardship to humanity so that people would either perish or awaken.
• Rin prepared for her date with Rimuru, while Shirou planned to meet Rin the next day and continued practicing to settle things with Rimuru.

Illya learned that Berserker’s Noble Phantasm had recovered while Archer continued defeating Servants, and Rimuru, Rin, Saber, Shirou, and Sylphiel went on a date that turned into a discussion of the Holy Grail War. Rimuru claimed Berserker would soon leave the stage, but he had not yet explained why.

• Illya corrected her attendant’s claim that Berserker had been defeated and asked for information about the Archer who had defeated Assassin and Rider and was fighting Caster.
• Rimuru woke Rin, and she, Rimuru, and Sylphiel met Shirou at his home; Fujimura Taiga prepared an outfit for Shirou before they set out together.

• The group chose the food street and discussed their enemies, with Rimuru saying Berserker would soon leave the stage.
• Rin fed Rimuru cake, Sylphiel tried to do the same, and Saber took Sylphiel’s unwanted cake as Rin demanded an explanation for Rimuru’s claim about Berserker.

Rimuru and his allies were ambushed by Caster, who tried to force Shirou Emiya and Saber to join her by revealing another way to summon the Holy Grail. Shirou refused, and Caster moved to use Fujimura Taiga against him.

• Rimuru explained why Caster would not ally with the other groups and revealed that Illya von Einzbern was the Lesser Grail, provoking Shirou and Saber before promising to explain.
• Illya wondered what Rimuru knew about the previous Holy Grail War while her servants reminded her to focus on defeating him and obtaining the Grail.

• Rimuru took control of the water and overwhelmed Caster until she summoned the unconscious Fujimura Taiga as a hostage.
• Caster offered to help Shirou fulfill his wish and claimed she could summon the Holy Grail without defeating every Servant, then urged him and Saber to submit to her.
• Shirou refused Caster because she harmed innocent people, and she began pulling Fujimura Taiga closer.

Rimuru intervened in Caster’s attempt to take Shirou Emiya’s Command Seals, disarming her and revealing that he had already secured Fujimura Taiga. He left Caster and Shirou stunned as he called them both fools.

• Caster threatened Fujimura Taiga and demanded Shirou Emiya surrender his Command Seals, while Rimuru warned her and Rin planned an attack.
• Shirou Emiya offered his arm to save Taiga, but when Caster attacked, his Command Seals activated and restrained Saber.

After Caster’s defeat, Souichirou Kuzuki chose to fight on for her wish and was killed by Rimuru. Rimuru set his sights on Einzbern to seize the Lesser Grail, while Saber and Shirou remained caught between his plans and their own convictions.

• Souichirou Kuzuki rejected Kirei Kotomine’s offer of a new Servant, explaining that he would continue for the sake of Caster’s wish.
• Kirei Kotomine grew angry at Kuzuki’s conviction, and Gilgamesh suggested that he envied Kuzuki for finding a human purpose.
• Rimuru ended the Reality Marble after killing Caster, leaving Rin, Saber, and Shirou to confront the consequences of the battle.
• Kuzuki attacked Rimuru in the park and was killed by a golden blade; Rimuru told Shirou to bury him and learn from his conviction.
• Rimuru refused to return Saber to Shirou and announced that he would go to Einzbern to seize the Lesser Grail, with Rin and Shirou accompanying him.

Rimuru and his companions headed to the Einzbern castle, where Kirei Kotomine tried to enlist Illya against Rimuru’s faction. Illya refused, the castle came under attack, and Rimuru realized Kirei and Gilgamesh had been chosen by the Holy Grail after he rejected it in the previous war.

• Rimuru transferred Saber's Command Seals to Animusphere, changing Saber’s Master and strengthening her attributes.
• Rimuru’s group entered the Einzbern forest while Illya watched them through a crystal ball and agreed to let them approach.
• Gilgamesh and Cú Chulainn appeared inside the castle with Kirei Kotomine, who asked Illya to ally with him against Rimuru’s faction.
• Illya refused Kirei’s offer and declared that she would side with the stronger faction, so Kirei and Gilgamesh prepared to attack her.
• Rimuru explained that Kirei intended to seize the Lesser Grail and activate it by another method, then realized the Holy Grail had chosen Kirei and Gilgamesh after Rimuru gave it up.

• Rimuru asked Illya what she personally wanted and offered to tell her the truth about ten years ago while keeping Berserker by her side forever.

Rimuru revealed the truth about Kiritsugu and Illya, then used the Third Magic to give Illya a new body and free her from her failing homunculus body. He asked Alaya to restore Heracles so Illya could have him as her Servant, while Gilgamesh refused to cooperate and remained set on fighting Rimuru.

• Rimuru asked Illya, Gilgamesh, and Kirei Kotomine to accept his proposal, but Gilgamesh refused and explained that he sought to keep the world interesting in memory of Enkidu.

• Rimuru pierced Illya’s heart, then used the Third Magic to turn her soul into a new physical body and destroy her failing homunculus body.
• Rimuru explained that he had chosen to save Illya because he could not accept killing a child, and he apologized for deciding her future without her consent.
• Sylphiel summoned Berserker again, and Rimuru asked Alaya to restore Heracles without the weakening effects of Madness Enhancement.

Rimuru ignored Alaya’s refusal to fully manifest Heracles and instead materialized the weakened Berserker, nearly exhausting his magical energy. After deciding he would not turn Shirou Emiya into another Archer, Rimuru faced Gilgamesh, who accepted his challenge.

• Alaya refused Rimuru’s request to fully manifest Heracles, so Rimuru claimed Berserker and gave him a physical body at great magical-energy cost.

Rimuru relied on Avalon to survive Gilgamesh’s Star of Ea, but Gilgamesh used Kirei Kotomine’s Command Seals to unleash his temporarily restored prime and break through the defense. As Ea’s final attack closed in, Great Sage took control of Rimuru’s arm and formed a small shield.

• Gilgamesh struck Rimuru with two consecutive Star of Ea blasts, but Avalon kept him safe as the surrounding world and lower dimensions were destroyed.
• Rimuru realized Avalon protected him by severing the world beneath a higher dimension, then panicked when Gilgamesh revealed a Jewel Sword capable of bypassing it.

• Rimuru stopped Rin from using her Command Seals, explaining that he had not been weakened by the Holy Grail System and could not use them to boost himself.
• Gilgamesh launched his final attack, shattering Avalon; Rimuru cast layers of barriers, but Great Sage took control and formed a small, elegant shield at the cost of much of his magical energy.

Rimuru defeated Gilgamesh by reflecting his devastating attack with the Mirror Counter, then spared Kirei Kotomine and made arrangements for Illya’s future. As he prepared to face Shirou Emiya the next day, Lord Animusphere urged him not to hold back against Saber and offered to make her kill herself if she interfered.

Rimuru faced Shirou Emiya, who returned to the Holy Grail War with a Command Seal and a willingness to ally with Kirei Kotomine to claim the Grail. Animusphere gave Saber freedom to act outside Grail-related matters, and Rimuru ended by warning Shirou that he would make the bloodshed in Fuyuki City humanity’s last.
