A bespectacled student at Miyabigaoka High School who looks down upon Seika students. After insulting two students for taking an interest in chess, they hit him and Misaki forces them to go with her to apologize to him. When she discovers the reason why they attacked Koganei, she demands that Koganei apologize to her students as well. He agrees, only on the condition that they defeat him in chess, which Usui does with no trouble despite Koganei ranking fourth in the nation as a chess player. He was originally intended to be the president of Miyabigaoka High School Council द्वारा the author, but rejected द्वारा the editor.[2]
