Eyeshield 21 Devilbats Devildays

Eyeshield 21 Devilbats Devildays for the Game Boy Advance shifts focus from the American football matches of its source manga to depict the off-field experiences of its characters. The narrative centers on Sena Kobayakawa, a new high school student whose natural speed allows him to evade bullies and ultimately catches the attention of the football club's captain.

Yoichi Hiruma, recognizing this ability, recruits Sena to serve as the team's running back under the secret identity of Eyeshield 21. The primary gameplay involves navigating text-adventure style story paths, where player choices lead to various narrative conclusions. This structure is interspersed with a selection of mini-games that provide interactive diversions.
