Shouhei Kido drifts through school with no obvious enemies and no real friends—at least, that is what the surface looks like. The moment he and his best friend Genta leave, their classmates drop the masks. Aoi Nonohara—the girl Shouhei has quietly admired—turns out to be part of a group that has already decided he is not worth knowing. Their plan to stage a rejection and move on starts a chain of events that reveals just how deep the cruelty at this school actually runs.
