Nora, an unruly demon, has defied his superiors one too many times. For the sake of his ""education,"" Nora is sent to live among mortals and enters a bond of servitude with cool-as-ice star student Kazuma Magari. Kazuma is about to learn the ways of the underworld...and Nora will learn more from the ""real world"" than he ever thought possible!
Now charged with the powers of the Dark Liege, Nora has the ability to restore the balance between the Human World and the Demon World. But he can't do it without Kazuma, who just wants to go back to being a normal super-cool genius. With the two worlds colliding, it's time for Nora and Kazuma to join forces again…and for Nora's collar to come off!
