Saint Iris is forced to wear a chastity belt by her husband Yuri, the hero, and her "sexuality" is sealed. While she was living a careless life, a ferocious man like a demon appeared before her. His name is Magreth. He was the demon lord who ruled the demon world...! Thus, an immoral love story in another world begins between a sexual harassment demon king, a rejected saint, and a moral harassment hero!
