Tooru Kouno

He is the primary protagonist of the story who transfers to an all-boys school and becomes one of the Princesses. He seems enthusiastic about it since all the Princesses get a lot of free stuff and added luxuries. His parents died in an accident, which is when his uncle and aunt adopted him. He seems to be very reluctant about spending time with his family, which mainly has to do with his younger step-sister Sayaka, who has an unhealthy obsession with him. He mainly uses his job as a Princess as a distraction from the problems he has with his family and in effect usually gets very in to acting like a Princess, much like Yuujiro. He often teams up with Yuujiro to tease Mikoto, much to Mikoto's chagrin. Yuujiro often jokingly says he and Toru are lovers.
