Kamui Gakupo

Kamui lives in a large palace. He is an earl who likes to have fun with human lives, he himself is a demon. Len is his dear butler who is 14 years old, he adopted him from an orphanage when he was 6 and has since raised him as his faithful servant on whom he can rely. Also sometimes Kamui is played with Len. By dressing him as a girl, he pretends that he is one of the princesses he wants to have. Even Len does not know what is happening in the basement of the estate, only you know.
