Sayo was born to a family of constant misfortune, but now finds herself in the mansion of a powerful demon. This mysteriously charming demon seeks Sayo's body, seething with the energy that once was his own, and offers to keep her father safe after he was falsely imprisoned. Night after night, the two slowly indulge in one another, but what was once only the desire to take back the energy that was stolen from him by Sayo's ancestors has suddenly come to be a desire to truly live together. As such, he grows more protective of her, especially after what had happened with Ogul. However, it seems that there are others amidst the area around the mansion that have their eyes on Sayo...?
