Plot
Karasu is an angel of the class Powers; Shirasagi is a demon, a Marquis. One day Karasu is assigned to convince Shirasagi to return to Hell. However, Shirasagi doesn't act like a demon at all—not only is he a priest, but he's forsworn the use of his demonic powers, and wishes nothing more than to live his life as a human. But the Archduke of Hell also has his eyes set on Shirasagi, and Karasu's own deviant behavior soon throws him out of God's favor. Will the pair be able to overcome the restrictions and laws of being an angel and a demon and live their lives freely?

Characters

 * Karasu (からす): He is a jaded angel of the class Powers. His first assignment was to convince Shirasagi that he should return to Hell. But he realized the odd personality within Shirasagi, as Shirasagi tends to not behave or do anything that relates as a demon. Confounded by this discovery, Karasu becomes more attached to Shirasagi, and wants to protect and stay with him at all times.
 * Shirasagi (しらさぎ): He is a demon of the priest class who seeks redemption. One day, when Karasu approached him and tried to convince him to go back to Hell, Shirasagi refused and explained that he wanted to be human. He forsworn the use of his demonic powers and wishes nothing more than to live his life as a human.
