Koganei

As the president of the chess club at Miyagaoka Academy, Koganei often looks down on students from Seika High, frequently using insulting terms like "flies" and "stupid poor people." He is extremely proud, and when he caused trouble with two Seika students, he ended up getting punched—a consequence of his own actions. Afterwards, he became angry that the Seika students did not apologize and tried to escalate the situation into a school-wide issue. However, after Misaki Ayuzawa learned the truth, she demanded that he apologize and arranged for him to face Takumi Usui in a chess match. Although Koganei is ranked fourth in the national chess tournament, he is completely no match for Takumi and suffers a crushing defeat. In the end, he seeks help from Tora Igarashi, but Tora coldly rebuffs him. According to the author, his initial setting was "student council president of Miyagaoka Academy."
