Kazeshini, despite being free of Muramasa's control, attacks Hisagi when he, Ikkaku, Izuru Kira and Tetsuzaimon Iba go on a mission to fight Sword Fiends in the Rukon District. After killing a Sword Fiend, Kazeshini finds a dying man who begs him to take care of his child. Kazeshini is frequently annoyed by the child's behavior, but often shows concern for it, and abandons a chance to attack Hisagi when he hears it crying. After defeating another Sword Fiend that is attacking a woman who came for the child, he leaves the child with the woman and goes to confront Hisagi. Kazeshini faces Hisagi in one last fight, but is distracted by the child crying, and is defeated and turned into a normal zanpakuto.
