“If you like being fucked by someone you hate, I'll do it.”

An exiled angel and a demon in a see-saw game of dog-and-monkey friendship!

Mitsuya and Kuga are the senior and junior members of the company, a “demon” and an “angel” who were reincarnated as humans after being banished from the heavenly realm for a “certain crime”.

Mitsuya tries to return to the heavenly world by showing his superiority, however, his “natural enemy,” Kuga, a former angel, always interferes with him.

Why is even Kuga in the human world after being corrupted? He does not know the reason, but anyway, Kuga's presence bothers him a lot.

One day, Mitsuya suffers from a severe headache caused by an argument with Kuga and loses consciousness due to a sudden lack of magical power. He is saved by Kuga, but the way he is saved is by “supplying magic power through sex...!”
