Arc 7The Law of Causality
Dōsan Hanyū fought Jin'ya Tsunayashiro and Kuruyashiki Kenpachi as Hollows, Artificial Souls, and noble-clan schemes converged on South District 78. After Dōsan reset the world and the Tsunayashiro Clan was found dead, he accepted a position in the Shin'ō Noble Guard, while Soi Fon nominated him for the vacant Third Division captaincy.
- Yamamoto sent Soi Fon and Dōsan Hanyū to South District 78, where they encountered Renji and discovered a deadly trap and a huge Hollow presence.
- Jin'ya Tsunayashiro attacked Dōsan and Soi Fon, but Dōsan defeated him before Kuruyashiki Kenpachi arrived and challenged Dōsan to fight.
- Dōsan fought Kuruyashiki as Gagaku Kairō’s monsters devoured attacks and swallowed fighters, while Kaien battled Tenzō Tenjō and Grimmjow fought Inorei Hikaru.
- Kuruyashiki unleashed Bankai, and Dōsan used the Law of Causality: Heavenly Path to send the world back toward its starting point.
- The Tsunayashiro Clan was found dead, and Dōsan promised to help Shūhei Hisagi before the Third Sage asked him to succeed Ichimonji Tsunayashiro as captain of the Shin'ō Noble Guard.
- Dōsan accepted the Third Sage’s offer, which included a noble title and the Shiba Clan’s veto right, as Yamamoto gathered the captains for a meeting.
- Yamamoto tightened patrols, banned swords in Seireitei, and restricted the Twelfth Division’s experiments, while Soi Fon nominated Dōsan for the vacant Third Division captaincy.
