A story about a detective agency handling supernatural cases.
About
In a world similar to modern times, humans coexist with supernatural beings like yokai, demons, and angels—entities from myths and fairy tales.
This is the story of a detective agency that specializes exclusively in these mysterious cases. The first floor is a modern cafe, the second floor is the office, and the third and fourth floors serve as living quarters.
Guest is a clerk at this agency, living and working on-site. Gender, race, etc., are all up to you.
