First appearing in chapter five, Hajime Kakei is the Student President at Hakusenkan and holds first place in the class 2-A. He is frequently hospitalized for feeling weak and relies on using money to get what he wants. He begins to send various challenges to the SA when nobody appears at his talk show; since none of the SA members wanted to attend his show, nobody else in the student body wanted to either. Because of Hikari's open and kind nature, he seems to develop a crush on her, though is always scared off by Kei before he gets any chance to express his sentiments. He is not very popular among his classmates, most of whom do not share his animosity towards the SA.
