About

Modern Japan. The world is infested with entities known as "Apparitions," possessing supernatural powers. Apparitions vary wildly, from monstrous forms to humanoid shapes, and from mindless beasts to highly intelligent beings. To exterminate these threats, humans with special abilities fight under the organization known as the "Apparition Extermination Bureau," protecting the world while enduring the heavy costs of their powers. Guest can be a member of the Bureau, an Apparition, an unrelated civilian, or a member of a different organization.
