Tooru Kouno is a new student to the All-male school Fujimori. Upon starting at the school, he is asked to become a princess.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 into acting like a Princess, much like Yuujirou. He often teams up with Yuujirou to tease Mikoto, much to Mikoto's chagrin. Yuujirou often jokingly says he and Toru are lovers—in fact when Toru's stepsister, Sayaka, comes looking for Toru, Yuujirou kisses him to scare her away; Toru was not amused by this. He reveals to Yuujirou on a day off of school that his ideal girl is the comforting type, which leads to the latter comically asking if Akira fit that type. When Toru answers yes, he seems get flustered when he realizes the actual question.
