The final battle reaches its climax. Aizen, transformed by the Hōgyoku into a quasi-divine entity, seems untouchable after sweeping aside the most powerful captains of Soul Society. Only Ichigo, having merged with his Hollow instincts and unleashed his ultimate raw power, stands before him in a cataclysmic fight that shatters reality itself. To defeat a self-proclaimed god, Ichigo must sacrifice everything he is, unleashing the ultimate Getsuga Tenshō at the cost of permanently losing his Shinigami powers. Aizen is finally sealed, but the spirit world and that of the living forever bear the scars of this merciless war.
