The series takes place in Tokyo, Japan, where the members of Deimon Devil Bats have the ambition to compete at the Christmas Bowl, the most important high school American football championship of the country.

The main character of the series is Sena Kobayakawa, a wimpy boy who was a gofer to avoid being bullied during his childhood; he enters Deimon High School. While he runs away from the Ha-Ha Brothers his running ability is witnessed by Yoichi Hiruma, the captain of the Deimon Devil Bats, the school's American football team.

Creation and conception

When Riichiro Inagaki and Yusuke Murata were creating the ''Eyeshield 21'' series, Murata was concerned that each character had a stand-out quality because many of them are in groups.

Eyeshield 21

is the title of the best runner of a generation. At the start of the series, Hiruma assigns this name to Sena to frighten his adversaries by claiming he is the running back who came from Notre Dame to Japan. "Eyeshield 21" is in fact not a person but a tradition of the college affiliated to the University of Notre Dame to distinguish the best player of the team. Shun Kakei, however, reveals he had already met "the real Eyeshield 21" when he was in the United States, and he returned to Japan to search him. During the match between Deimon Devil Bats and Bando Spiders, Akaba Hayato claims for himself the title; after being defeated by Sena, he admits that Sena can be the title holder. But, the "real" Eyeshield 21 is Takeru Yamato, who was the person Kakei met in the United States. When he meets Sena, Yamato declares that whoever wins the confrontation between them is the one who deserves such title.

Santos affirmed the series has "hilarious characters", while Scott Campbell from Active Anime said the characters "also possess a lot of ability to make the reader laugh".

Scott Green of Ain't It Cool News described the characters "recognizable as people" and praised ''Eyeshield 21'', for "taking the personal relationships a little less serious, but going a bit overboard with the motion and personalities". Mania.com's Jarred Pine classified the characters as "very likeable", and said that because they have "their own personalities" they "are instantly memorable". Chris Zimmerman from Comic Book Bin praised the development of the characters through the manga series. Chris Homer of The Fandom Post also commended the characters' development in the anime series and said that some of them, such as Ikkyu and Ishimaru, were better developed in comparison to the manga.

Santos commented, "Just as thrilling as the game highlights are the individual stories and rivalries behind each player". On the other hand, ''Eyeshield 21'' has a lot of teams with different themes and according to Chris Beveridge from Mania.com some times "the theme is used more than it should" and that "it just feels very forced".
