Ghoul: Starting from White Dove

It is a story about a certain man who is inferior to others and is voluntarily forced to go to the world of ghouls and become a female ghoul investigator to expel the ghouls. There is no male protagonist, so Lily depends on the situation. "Is this the world of ghouls? It's really troublesome. Forget it, I have to work hard to survive!" I will also go to other worlds in the future, such as: Tanya, the Cute King, the Witch of Crush, etc. You can tell me what you like. I am a student, and I will try my best to update on time.
