Hanataro Yamada, Nanao Ise and Ikkaku Madarame are sent to investigate some thefts that have taken place, and track the culprit to the sewers. They discover a white, doll-like figure, and are then attacked by a large monster, which manages to injure Ikkaku. The strange figure heals Ikkaku and fires a powerful blast at the sword fiend, defeating it. It is revealed that the doll is Hanataro's zanpakuto, which had resisted Muramasa's control because it did not resist Hanataro. The group returns the stolen items, and Hanataro realizes that he has accidentally left his zanpakuto behind in the sewers.
