Michiru, Chika and Sotetsu arrive late at night at a closed JRail station which is rumored to be haunted. Their aim is to seek out the Grim Reaper who like the master of the black rings, knows of all souls passing through the dimensions. Preparing to engage the reaper for information on Shito's whereabouts, they are surprised that he has turned into a chibi state, as a result of losing his Astral power core as thus, his body. Having a soft spot for such cute characters, Michiru takes the reaper along in their investigation. Meanwhile, Otsu follows his own leads on a suspicious mortician at his workplace as the groups end up together to confront the mastermind of Shito's kidnapping.
