The student council president of the Miyaji Academy High School Division deems Aichi's Cardfight Club to be unnecessary for the school and orders the vice president, Suwabe, to devise on how to abolish it. Elsewhere, the Cardfight Club finds an empty classroom to serve its official headquarters. Then, the school's American football team, the Miyaji Vipers, barges in and takes the club outside to the academy's sub-ground where the Vipers' quarterback/captain, Ikki "the Catapult" Kongou, challenges Aichi to a cardfight, with the former appropriately using a Spike Brothers deck. This is an elaborate plan set up by Suwabe to have Ikki defeat Aichi and thereby crush the Cardfight Club members' spirits into not wanting to continue the club. Ikki uses strong Limit Break effects of the latest Spike Brothers to push for victory, but Aichi successfully defends and makes it to his next turn.
