Eiji Hoshimiya is an introverted high school student who hides a huge secret: as a child, he wished for the world to be destroyed. Fairies grant certain people special powers known as Orders, and what each Order User can do depends on what they wished for. Ten years after the Great Destruction, Eiji is still struggling to accept the immense power he holds. This single-episode action OVA shipped with the limited edition of the eighth volume of the Big Order manga, and its story branches so that viewers can pick their own route.
