Sena's been at the mercy of bullies all his life, and things aren't looking much different in high school.

Then the desperately short-handed American Football club ropes him in as a member, and Sena hopes to simply be the club secretary.

The demonic team captain Hiruma has other plans for him, though. Sena's years of evading bullies has given him speed and maneuverability! Hiruma puts an eyeshield on Sena to hide his identity, and puts him on the field as the team's secret weapon: a running back faster than any other, except possibly the great Shin.
