Arc 6Dōsan at the Center
Dōsan Hanyū defied his confinement to save Soi Fon, defeated Tenzō Tenjō, and returned to Seireitei under a three-month sentence. After becoming a kendo teacher at Shin'ō Academy, he was drawn into a conspiracy involving Aizen and faced new danger as Soul Reapers began accusing him of a crime.
- Dōsan left Seireitei against Yamamoto’s orders to help Soi Fon, and Komamura allowed him to go with Iba and Murashita.
- Dōsan defeated Tenzō Tenjō in the World of the Living, but Baraggan’s group took the fallen Tenzō away before Sasakibe arrested Dōsan.
- Central 46 sentenced Dōsan to three months in prison, after which Sasakibe assigned him to teach kendo at Shin'ō Academy.
- Dōsan challenged Number 360 in a series of sword matches, matched her technique, and realized physical technique could advance his Shunkō training.
- Byakuya trained with Dōsan, warned him that a crisis tied to a case from fifteen years earlier was coming, and urged him to leave Seireitei.
- Mud Hollow possessed Byakuya, who ran onto Dōsan’s blade, while Honrō Useki died after confronting Tōsen and Aizen’s conspiracy.
- A Sixth Division squad tried to detain Dōsan, but Soi Fon and Ginrei intervened before Sasakibe summoned her to Yamamoto’s emergency meeting.
