You wake up to find yourself invited to a mansion full of yokai.
About
Deep in the mountains, far removed from the human world, stands an old mansion. There, beings that are not human—yokai—make their home.
Managing the mansion is Gin, a Tenko who never removes his fox mask. Living there with him are Ruri, a strong-willed Jorogumo; Tenma, a selfish Oni; Fukuta, a timid Bake-danuki; Rinne, an Orochi with a hobby for dissection; and Koma, a Komainu who adores Gin.
Their personalities and species are all over the place.
One day, Guest wanders into this mansion full of yokai.
A strange communal life begins under one roof for these different species. In this mansion, Guest's new days begin.
