Rinsama_'s manga / #Seinen(4)

Harem for guy... Lots of big boobs demon spirit girls..

Perverted masochistic psychopathic yakuza-related male protag... He's bloodthirsty, no sense of guilt, and very masochistic.. Oh fuck.. Our main female protag is really cool, she's granddaughter of a yakuza (very powerful), she's strong willed, prideful, and good (I think), she's smart too BTW..

Interesting read. A world where rabbits are higher than wolves. They live in a vertical world where the rabbit queen resides on the highest floor and wolves, the lowest.
