Riki Densetsu

Riki, a third-year student in Hanazono High School, is a prospective soccer player and a member of the sports' club. However, the cheering squad of the opposing school in the upcoming prefecture tournament attacks and injures the players of the club. Angered, Riki attacks and beats up the cheering squad, but this draws the attention of the police, who take custody of Riki and take him to the nearest station. The following day at the principal's office, Riki is sentenced to a half year suspension and the soccer club is disbanded.

This incident is the catalyst for Riki's fall from grace. Shortly, powerful enemies begin attacking Hanazono High School one after another, with the intent of taking control of the school. It is here that Riki builds his legend, with his deadly "Mach Punch".
