Nora is a demon who often doesn't acknowledge the authority of the Lord of the Demon world: The Dark Liege. One day, when Nora goes too far (A.K.A: calls the Dark Liege 'ugly' one too many times), Nora is sent to the human world and unwillingly bonded to a human in a familiar spirit contract! What does that mean? Nora needs permission to use his powers!

Follow Nora and his new master, Kazuma Magari as they fight off outlaw demons and reveal the secret history of the Dark Liege as well as Nora's heritage as the Super Demon, Cerberus the Hell Hound!
