Seikyou Academy is an ever growing collection of buildings and structures. There are classrooms that became storage, stairs that no one climbs, and hallways that end abruptly. Teiichi is lost in one of the older sections alone…

All the mystery have been solved, Yuuko is whole once again. But now that she has no regrets anymore, can she still remain a ghost?

Tired of Yuuko's antics for causing more ghost stories to be spread amongst the students, Kirie challenges her to a series of games which if Yuuko loses, she must behave.
