Eyeshield 21 is a Japanese manga series written by Riichiro Inagaki and illustrated by Yusuke Murata. The series tells the story of Sena Kobayakawa, an introverted boy who joins an American football club as a secretary, but after being coerced by quarterback Yoichi Hiruma, becomes the team's running back, whilst wearing an eyeshield and the number 21, under the pseudonym of "Eyeshield 21". Inagaki chose American football as a central subject of Eyeshield 21 after realizing that it fit perfectly with his idea for the series.
