Ichigo reports his findings of Muramasa's abilities to Ukitake, Shunsui and Unohana. In order to find out about Muramasa's effects on zanpakutō, Ichigo and Ikkaku patrol Seiretei to seek out the entities. Meanwhile, someone breaks into a compound and... (more) knocks out the Soul Reapers guarding the area. Ōmaeda and his men stumble on the unconscious guards and investigate, only to encounter his zanpakutō spirit, Gegetsuburi and Hozukimaru. Ōmaeda and Gegetsuburi are just about to fight when Ichigo and Ikkaku interrupt. Ōmaeda is knocked out of the fight, leaving Ichigo to battle Gegetsuburi, while Ikkaku fights Hozukimaru. Ichigo defeats Gegetsuburi but Ikkaku is wounded by Hozukimaru's bankai. Just as he attempts to continue the battle, Ukitake, Shunsui, Soi Fon and her Stealth Corps arrive to surround Hozukimaru, but he uses his bankai to get away. However, they manage to obtain Gegetsuburi. Ichigo goes after Hozukimaru, but the entity escapes when Senbonzakura's petals block Ichigo's route. Ichigo discovers that the attack was from Byakuya, who disappears.
