A student who runs against Kagawa for the president position during the student council elections. His father is mentioned to be a famous politician. To most people he appears as a modest and charming student with good grades and influence.
Truth is that he is a former delinquent whose goal is to remove all other delinquents from Mon Shiro (except his team candidates). He and his fellow candidates fools the students into making them believe that they have nothing to with the dirty campaign against Kagawa's group and even manipulates Adachi and her group. After getting beaten by Adachi and realizing who she is, they stop their dirty tactics and concede to Kagawa's group. Since then, he has been on good terms with the other characters.
