Arc 15Calamity and Consequences
Kisuke Urahara secured Mayuri Kurotsuchi’s release and a new research institute, while Shibata Takanobu’s catastrophic Bankai and Arturo Platido’s invasion shook Seireitei. The story then followed the characters’ postwar choices and growing tensions, ending with Kuruyashiki stepping forward as Shibata left the Eleventh Division exposed to Quincy arrows.
- Kisuke Urahara persuaded Central 46 to approve a research institute and release Mayuri Kurotsuchi, then Murata Shō fought Eleventh Division veterans until Shibata Takanobu unleashed his devastating Bankai and was detained for assessment.
- As Kisuke Urahara traveled to Hueco Mundo with Shibata Takanobu and several captains, Arturo Platido emerged in Seireitei and led a Hollow invasion, which Zhu Sibo Zhengyuan and Shuichi fought before Redwater Mirror helped drive Arturo away.
- Seireitei’s fighters treated the invasion’s casualties, Zhu Sibo Zhengyuan resigned but agreed to delay pursuing Arturo, and Shinji Hirako accepted the Fifth Division captaincy while Kensei Muguruma became Ninth Division lieutenant.
- Kisuke Urahara traced the Hollow uprising to Arturo Platido, Gin Ichimaru graduated early, and Central 46 released Shibata Takanobu and appointed him Eleventh Division captain as the new graduates joined their divisions.
- Sosuke Aizen studied records about Arturo Platido, Shendu Wuming, and Bankai Hollowfication, while Kisuke Urahara removed a Soul King Fragment from Ge Kuang and Aizen secretly found it in his laboratory.
- After Tsunayashiro Tokinada admitted killing Ge Kuang, Sosuke Aizen intervened as Tōsen Kaname left, and Tōsen and Sajin Komamura later became friends before choosing the Ninth and Seventh Divisions respectively.
- Shibata Takanobu’s constant criticism wore down the Eleventh Division, and during a Quincy attack he stayed behind as Squad Members fell until Kuruyashiki cut down incoming arrows and advanced in his place.
