Manga by author Higuchi Daisuke

Whistle! is about a boy named Sh Kazamatsuri. He transfers from Musashinomori School to Sakura Josui Junior High School for better hopes to make the soccer team, since he never got a game at his old school due to his small stature. Yko Katori, his teacher, introduces him as a former star of the famed Musashinomori team, causing his classmates to be wrongly ecstatic. Right after that, one of the players, Tatsuya Mizuno, reveals that he was never a regular. In other words, since he never got the chance to play, Sh is a poor player. Sh struggles to improve his skill so he can make the team at his new school and to ignore the drastic disadvantage he has due to his height.
