Chiaki's classmate. He is nicknamed "Idiotic child" which his classmates believe is more of an impression of him than a nickname. He has a crush on Haruka, and goes as far as cross dressing (first forced upon him by Kana) to avoid detection from Chiaki, who became jealous and angry with him after he helped Haruka cook dinner, in order to see her at the Minami residence. When he crossdresses, he is referred to as "Mako-chan". (Source: Wikipedia)
