In this world reside fairies, beings who have a special power that resides in them, which can possess animals. By taking out the organs of these possessed animals and transplanting them into humans, they can invoke the powers of the fairies themselves and fight. They are then used weapons of war by controlling the soldiers within whom the organs reside, and are known as ‘Fairy Fighters’. After the long war has finally ended, their role fulfilled, they had nowhere to go. Some became part of the government, some became part of the mafia, and some became terrorists. They each chose their own path to walk.

Nine years have passed since the war ended. Mariya, the main character of this story, is a young girl who has just been assigned to Terotea. Terotea is an organization dealing with the investigation and subjugation of illegal fairy-related incidents as a fairy management agency. In the midst of an unstable government, criminals bearing horrible pasts and pains from the war, appear and commit acts of terrorism.
