Arc 15The Last Seven Days
After Aika’s death triggered Metatron’s judgment, Shirou gathered allies and prepared to stop the destruction of Old Humanity. His assault failed, and Metatron absorbed him, leaving him to awaken in a strange space beside a frozen Jeanne.
- Shirou watched Aika die from Semiramis’s poison, and Amakusa Shirou used the Holy Grail to begin his wish to save humanity.
- Jeanne Metatron emerged and declared that humanity would be destroyed in seven days, while Shirou took the sleeping Aika to Milenia Castle for treatment.
- Shirou trained Laeticia and gathered allies, as Fiore transferred most of her Magecraft Crest to Caules and left the life of a magus.
- Shirou restored Achilles’s will to fight and reunited with Atalanta, who became Atalanta Alter to gain power against the angels.
- Semiramis joined Shirou’s cause, and Shirou led the group from the castle to confront Metatron with support from the Mage’s Association and Artificial Lifeforms.
- Shirou captured angels and exploited their network with false commands, then Laeticia summoned Jacob’s Ladder to bring them to Metatron’s garden.
- Shirou unleashed Excalibur: Unlimited Excalibur Works, but Metatron survived, bound him, and declared that he would preserve humanity as its sole survivor.
- Metatron absorbed Shirou to give him another chance to become human, and he awoke in a strange space before finding Jeanne frozen in an ice coffin.
