EyeShield 21

The plot of Eyeshield 21 revolves around a weak, unassertive boy named Sena Kobayakawa who enters the high school of his choice, Deimon Private Senior High School, where his childhood friend Mamori Anezaki attended school the year before. His only remarkable physical abilities are his running speed and intense agility, the result of a school life spent complying with the demands of bullies. It was revealed later that a friend, Riku, taught him how to run fast to help him against bullies. His abilities quickly catch the eye of the high school's American football team captain Yoichi Hiruma, who forces Sena to join the Deimon Devil Bats as its running back.

To protect his identity from other teams who want to recruit him, Sena is forced to publicly assume the role of team secretary and enter the field wearing a helmet equipped with a green-tinted eyeshield in order to hide his features under the pseudonym of "Eyeshield 21." The makeshift team initially takes part in the spring football tournament hoping to win with through the strength of their new "secret weapon." However, the extremely weak team is eliminated early on by the Ojo White Knights, a powerhouse football team that focuses on defense.
