Arc 9The Law of Causality
Dōsan Hanyū confronted a reality-bending Domain, entered Central 46’s leadership, and became entangled in an attack by fighters from the future. He crossed into another world with Rukia, Renji, and Tōshirō, but emerged alone in Karakura Town, where Orihime and Tatsuki took him in.
- Dōsan maintained a barrier during the Visoreds’ battle with the Arrancar, then faced Jin'ya in a destructive Kidō and Hakuda duel.
- A prisoner’s Domain amplified hostility among the fighters, but Dōsan and Soi Fon broke the barrier while Tachikawa Magaki used Miroku to acquire his ability and confront Aizen.
- Magaki died after her poison failed to defeat Aizen, and Gin received her research and Aizen’s blood before Aizen concealed her final words with Kyōka Suigetsu.
- Dōsan refused to help capture Aizen, accepted the position of Central 46’s first sage, and later began teaching Kidō at Shin'ō Academy.
- Dōsan stripped Mayuri Kurotsuchi of his captaincy and learned from Soi Fon that the Kuchiki Clan’s sealed Zanpakuto, Universe, might help save Hisana.
- Tōshirō Hitsugaya attacked Dōsan and Soi Fon with powers linked to time, while other future fighters killed Yamamoto and several captains, and Yamamoto entrusted Soul Society to Dōsan before dying.
- Dōsan identified Renji and Rukia among the attackers, then took them and Tōshirō through a membrane between worlds, arriving alone in Karakura Town and accepting Orihime and Tatsuki’s help.
- Rukia woke in Ichigo’s closet, and Tatsuki’s attempt to cook for Dōsan went awry.
