Wandering Knight - Chapter 55: The Gift of Restoring Life

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

— Climax exorcism.

An obscene ability that forces forces anyone stricken by it to climax, regardless of whether they are living or dead.

As a bonus, it also forces evil spirits and monsters to ascend to heaven.

This is a world where evil spirits and monsters are everywhere and being an exorcist is a real job.

Talented boys and girls with bright futures are trained at the “School for Exorcists”.

Furuya Haruhisa is a boy cursed with the ability, climax exorcism, and is also the school dunce.

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!!

Lin An woke up and found himself in an Eastern Fantasy world.
