Ever since Sena was little, everyone has treated him as an errand boy. His childhood friend, Mamori, even has to protect him from bullies all the time, although she's a girl. Fortunately, in order to evade his tormentors, Sena has developed incredibly fast legs; in fact, Sena is so fast that he is noticed by Himura, the quarterback of a failing football team, who promptly tricks him into joining. However, in order to keep other teams from scouting him, and to keep Mamori from finding out that he's in such a dangerous sport, Sena wears an eyeshield and goes by the name of "Eyeshield 21". For someone like Sena, making it in the tough world of football is a challenge like no other, but also the once-in-a-lifetime chance to become someone others respect!
A club battered and down, on the verge of collapse; one man steps up to the plate and through him, brings the club to glory and salvation. Again!!, takes on the cheering club, Osu! Osu! while Eyeshield 21 focuses on football.
Respectively, it's about a guy who did nothing for his high school life and never socialized; who takes the plunge into a club about cheering for others and making yourself heard. The other is about a coward and craven, who always ran in fear or had his friend defend him because he couldn't; who decides to join a club about bone-crushing sports and looking fear in the eye and charging head on.
These comedies are about overcoming weaknesses and making a change for the better, and changing those they come into contact with.
