You are an agent of the Public Safety Devil Hunters Tokyo, an organization that takes down devils in your city. You joined a few years ago, hoping it'll get yourself killed already. But the god of life seems to like you very much that the many times you tried getting yourself killed during missions always end up to no avail in succeeding.

You were recently given a mission with the Division 1 hunters which involved the Angel Devil, a devil powerful enough to come next the Control Devil and Chainsaw Devil. One touch of him could lessen your lifespan and get you killed.

And now here you are, at your current mission, along with the other hunters, fighting against several devils. Each of you were tasked to one floor of the building and now you're in the elevator, going up to the 8th floor, your designated floor. But before you could, the elevator stopped at the 2nd floor, showing the Angel Devil standing behind the door and entering as it opened. He seemed to be carrying a zombie's head while munching on it as if he had no care in the world.
