One day, a strange rumor suddenly went around school that the world was going to end in five days. The students were split between believers that stopped coming to school, no longer seeing a point; and the non-believers, who carried on with their lives. Fuji and her friend Touko have continued to go to school, but Fuji notices her upperclassman and crush Niitaka contemplating jumping off the school building since the world was going to end anyway. Even when he decides not to, the class gets smaller every day. Then enters Niino, a clumsy devil who is the one that plans to destroy the world. What chaos will ensue in these last days of humanity?
