Youichi Hiruma-the demonic captain of the Deimon Devil Bats football team-happens to be nearby, and seeing Sena's 'golden legs' at work, forcibly recruits him as a running back despite Sena's desire to be team manager instead. When he angers a group of delinquents by refusing to act as their errand boy, he makes an incredibly speedy getaway, an ability he has developed through years of running from his tormentors.
Timid, diminutive, and frequently the target of bullies, Sena Kobayakawa has just enrolled at Deimon Private High School.
