Welcome to the Gridiron of the Damned! Huge, hulking bodies throw themselves at each other, while a tiny, lithe body runs between them toward the goal! No, it’s not a game of football, it’s Sena Kobayakawa trying to evade the monstrous Ha-Ha brothers down the halls of Deimon High School! But wait! Sena’s incredible skills at not getting caught have been spotted by the devilish (possibly actually demonic) captain of the school’s embryonic American-style football team. When Sena asks to be the team’s manager, he gets thrust onto the field as a running back instead! But there are two BIG catches.
