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.
Tras la derrota de Muramasa, la mayoría de las Zanpakuto se han reconciliado con sus amos y vuelto a su poder. Todas a excepción de Kazeshini, que sigue buscando matar a su antiguo maestro, Shuhei Hisagi.
村正の洗脳が解けたため、死神と斬魄刀はお互いの絆を再確認し、つながりはより強いものになった。しかし、檜佐木と風死だけは違った。風死はほかの斬魄刀と違い単独で行動し、隙を見ては檜佐木の命を狙う。
Dopo la sconfitta di Muramasa, la maggior parte delle zanpakuto si sono riconciliate e sono tornati dai loro padroni, ad eccezione di Kazeshini, che è ancora pronto a uccidere il suo ex maestro Shuhei Hisagi.
