Arc 20The Divine Realm Infiltration
As Ichigo’s allies prepare to confront Aizen, Shiraishi infiltrates the Divine Realm and works to uncover its barrier while Orihime is held there. Yhwach names Uryū his successor, and Grimmjow’s coming assault threatens the Shinigami in the lower world.
- Ichigo defeated Cang Du and found Rukia, while the real Retsu Unohana fought Royd and Loyd and ordered Ichigo to retrieve Kisuke Urahara.
- Yhwach named Uryū Ishida his successor, gave him Schrift A, and announced that the Wandenreich and Shinigami would attack the Divine Realm together to defeat Sōsuke Aizen.
- Kisuke Urahara set out a plan to plant Spatial Transfer Stakes in Aizen’s Pantheon, and Shiraishi infiltrated it disguised as Luko Vladimir.
- Shiraishi worked in the Great Spirit Book Library under Emilou Apacci, learned about the Divine Realm, and discovered that Harribel kept the barrier’s switch in a drawer.
- Ulquiorra captured Orihime after defeating Ichigo, then brought her to the Divine Realm, where Aizen ordered him to watch over and train her.
- Harribel and her companions searched for Shiraishi and Yamamoto, but Mayuri trapped them and forced Harribel to give blood for an antidote.
- Shiraishi revealed his identity to Emilou, Sun-Sun, and Rose and secured their cooperation, while Ichigo’s group prepared for the captains’ eventual arrival and Ichigo worried about Uryū.
- Shiraishi reassured Orihime that he had worked out how to open the barrier, while Gin announced Grimmjow would lead a hundred thousand Arrancar against the surviving Shinigami.
