In an imaginary world, there is a small group of "special ability people" who exist secretly, referred to as special ability people. They will not expose themselves to ordinary people, and through an autonomous organization, the Abnormal Control Bureau, they manage various unnatural events caused by special abilities and maintain social order. However, as time goes by, the positions of the special ability people are divided. Some want to protect peace and maintain balance, while others want to use their special abilities to gain personal benefits. Conflicts are imminent.
