Onboard the Aerial Cityship Musashi, the students of Ariadust Academy go about their daily lives. They begin a game of "Tag" which is part of their classes, where any kind of attacks and traps are allowed but the hero, Tori Aoi is not with them. Where has he gone, the "impossible" because of his lack of talent, the head of the student council?
