Using the ability could lead to his own social death…

But then, Haruhisa met her.

Misaki Soya, a girl possessing a similarly cursed pair of eyes — demon eyes.

And so begins the legend of how history’s worst exorcists came to be known as the strongest before anyone realized it. Their first official job results in a grand performance with a monster woman who runs away from boobs.

— Nhoooooo!?

A coquettish voice echoes throughout the neighborhood tonight.

It is undoubtedly evidence of an ascension.

Are those useless exorcists using their obscene abilities?

Is ero going to save the world?

A slightly ecchi exorcism performance!!
