The 3 elites are gloating over their success when Koga and Muramasa appear. Koga kills them, and Ginrei is informed. Muramasa talks to Koga to try and help him over his anger, but they are found by Ginrei. He inform Koga the likely sentence for killing the Elites is execution, and Koga goes insane. Muramasa tries to possess Ginrei’s Zanpakuto, but phases through Ginrei. Koga removes his hairpiece, and departs. He then goes on a killing spree. Muramasa tries to reason with him but fails, lamenting that he can’t hear Koga anymore. Yamamoto is informed of what’s going on, and Ginrei tells them how to resist Muramasa’s power, and Yamamoto volunteers to help. Koga rants at Muramasa and threatens him. He meets Ginrei and Yamamoto for a showdown. He tries to use Muramasa on them, but he won’t release. They use this opportunity to arm with the spears used to seal Koga’s coffin. These immobilise his limbs, allowing Yamamoto to use Kido to imprison him. Back in the present, Koga thinks Muramasa betrayed him, but Muramasa claims he never heard him. Koga removes his blade from Muramasa, and tries to kill him, but Byakuya blocks the blow and challenges him.
