Now a freshman in high school, "Devil Ma-kun" is hoping to reform his image after being labeled a delinquent in junior high due to his tough appearance, which caused him to get into a lot of fights. His explanation is that after winning one fight the losers comerades challenged him as well, and after their losses more and more people started challenging him to fights. While hoping to discard his bad image he tries to join a club, and chooses the tea club as it is the only one who's representatives are not to afraid to ask him.
