He is a very handsome student at Chiyukis school who is very popular among the girls. He tends to be very suave and flirts a lot with the female students. As noted by Chiyuki he also has a great sense of humor. Satsuki lives with his grandmother and has been able to gain a lot of her wisdom because of it. Also like Tya he is not a human but in fact a werewolf. It is due to this that he constantly tries to appear as a normal person. If he didnt he would always feel very insecure about him being a werewolf. He also seems to care a lot for Chiyuki and likes to protect as well as flirt with her to annoy Tya.
