Aki Mizushima

Mizushima is like Tsubasa a first year and a member of the band. He is very good at playing the trumpet. In the beginning he tells Tsubasa to leave the club because he thinks she only joined with lighthearted feelings. He says she would only drag down the club since other members wouldn039t have time to practice when they039re tutoring Tsubasa. Later though he accepts her and believes that she039s serious about joining the band. All the time Tsubasa mistakes him for a girl until Daisuke meets him once and tells her that Mizushima is a guy.
