A trunk that was distorted by Ryoichi Aizawa at the scene of a confused accident. Inside was a girl who wasn't wearing a single thread, like an elaborate doll that was curled up to hold her knees. Is she a dangerous weapon, or is she a tool of some sort? Ryoichi has seven pieces, a map, and a stuffed rabbit.
