Climax Exorcism.
It is an obscene ability that forces a someone to climax when stimulated, whether they are dead or alive, and also causes evil spirits and monsters to ascend to heaven when they cum.

After all, if he uses his ability, he will die (socially) in many ways…

But Haruhisa has met someone, A girl named Misaki Souya, a girl with an evil eye capable of exposing people’s secrets. This is the story of how those who were called the worst, and the worthless degenerates exorcists become the strongest ones in history.
