Ch. 1836All Self-Inflicted
Gilgamesh used the Chains of Heaven and the Key of Heaven to unleash his full abilities and attacked Anno, while Kirei Kotomine ambushed Irisviel and Maiya Hisau at the castle. Maiya was quickly defeated, and Irisviel prepared to fight Kirei rather than flee.
- Gilgamesh wrapped himself in the Chains of Heaven and drove the Key of Heaven into his own heart, breaking free of his Archer-class restraints.
- Gilgamesh charged Anno, and their sword-and-spear clash began a fierce battle on the eastern side of the castle.
- Maiya Hisau led Irisviel toward the castle's northern escape route but found Kirei Kotomine blocking their way.
- Maiya fired at Kirei, but he dodged, disarmed her, and struck her down with a rapid series of blows.
- Irisviel refused to flee and said they had to kill Kirei to be safe, then drew a glowing blue ribbon-like object.
