I can't remember the name but it's a vn where the mc has familiar/servant demon to help him to solve the supernatural thing happening in that town. He has like 3 familiar a catgirl named aoi, a demon who's in charge in chores, and a gothic lolita. There is also another demon but she's a shut in as far as i remember. There is also a ghost girl who doesn't know that she's a ghost. I've only gone through her route so the ending is like finding her killer and then scare the shit out of him with the mc's demons
