Watch Eyeshield 21
Eyeshield 21 is an anime that ran from April 2005 to March 2008, with a total of 145 episodes. It is based on a manga series of the same name written by Riichiro Inagaki. Besides the TV show, the manga also spawned a movie, video games, and a trading card game.
The show centers around American football. The main character is Sena Kobayakawa (voiced by Miyu Irino in the original version and Yuri Lowenthal in the English dub), a high school student who is frequently bullied but turns out to be a very talented football player, thanks to his great speed and agility. He joins the Deimon Devil Bats football team under the pseudonym "Eyeshield 21," a name given to him because of the green-shielded helmet he wears during the games to hide his identity, since rival teams will want to recruit him if they find out how truly talented he is. Early on, the series focuses on one game per episode, following the training and drama on the football team. The series ends with several episodes about the final game between the Devil Bats and their ultimate rival, the Oujou White Knights.
Other major characters who appear throughout the show include Devil Bats quarterback, team leader and tactician Yoichi Hiruma (voiced by Atsushi Tamura in the Japanese version and Derek Stephen Prince in the English dub), cheerleader captain Suzana Taki (voiced by Shoko Nakagawa), and Sena's childhood friend Riku Kaitani (voiced by Yuuki Masuda).
The first several episodes of Eyeshield 21 were released with dubbed English voices, but production on the English dubs ceased before all the episodes could be finished. All 145 episodes are available with subtitles.
