楢崎 流星

A 20 years old university student. Third son of a bureaucrat. A womanizer. His older brothers are so talented that no one expects anything from Ryusei. He's left to take care of himself no matter how much he goes out partying. He has tons of casual sex partners, and crashes at various women's places without going home. He has money, so he doesn't burden anyone financially, but he likes to be pampered by serving others with his body and soul. [From MangaGamer]
