Looking for Books About Catching Ghosts, Killing Ghosts, Physically Exorcising Ghosts, Torturing and Killing Ghosts, and Worrying About Ghosts.

It doesn't matter if it has a female protagonist or not. If the protagonist doesn't want a female protagonist, that kind of article is boring to read. The protagonist is a normal person, and when he kills ghosts, the ghosts are afraid of it. It doesn't matter if you have a system or not! ! !
