Kaieda, the principal of Hinamizawa School, first appears in Onikakushi-hen and later helps Keiichi and the Club convince the youth office to save Satoko from her abusive uncle Teppei in Minagoroshi-hen. In a scene from Onikakushi-hen, it is revealed that Kaieda is ashamed of his bald head. He traveled around the world to become a martial arts master and later became an educator due to his concerns about Japan's corrupted educational system after World War II. The students believe that he is responsible for Hinamizawa School not having any delinquents.
