Kaieda is the principal of the Hinamizawa School and he first appears in Onikakushi-hen. In Minagoroshi-hen, he helped Keiichi and the Club convince the youth office to save Satoko from her abusive uncle, H�j� Teppei. During a scene in Onikakushi-hen, it is revealed that he is ashamed of his bald head. He traveled all around the world to become a martial arts master. He also became an educator "after being concerned about the corrupted educational system of post-war Japan". The students believe he is the reason why no delinquents attend Hinamizawa's school.
