Arc 19The Grail and Reikaku Rebellion
Ailin defeated Iskandar, Artoria, Gilgamesh, and the corrupted Holy Grail, then returned to Seireitei as the Reikaku rebellion erupted. After the rebellion ended, the captains gathered to decide how to compensate Ichigo Kurosaki for his sacrifices.
- Ailin crushed Iskandar’s army in Unlimited Blade Works, defeated Iskandar with his Shikai, and spared Waver, who vowed to preserve Iskandar’s story.
- Ailin fought Artoria to analyze Avalon, defeated Gilgamesh, and later killed Artoria after her Command Spell enhancement weakened.
- The Holy Grail transformed Irisviel and revealed that Kiritsugu’s wish would destroy humanity, so Ailin entered Unlimited Blade Works to confront Angra Mainyu and his corrupted past self.
- Hollow Ailin fused with the Holy Grail and challenged Ailin, but Ailin used Ittou Shura to overwhelm him and seize control of his spiritual pressure.
- Ailin helped restore order in Seireitei, took Aizen to Mugen Jigoku, and left Souya Jōshirō to choose Aizen’s confinement.
- Inaba Kagerōza fused with Kujo Nozomi to restore Yushima Oshu, but Ichigo, Rukia, Renji, and Komamura defeated him and ended the Reikaku rebellion.
- Months later, Yamamoto asked the captains to decide how Seireitei should compensate Ichigo, and Ailin urged him to present the plan he had already considered.
