After reporting to the student council president about the Cardfight Club's loss at the Kanto regional tournament, Suwabe moves on to his next plan of terminating the club. He gets the Paranormal Power Research Society, a group of delinquent-looking students who are interested in supernatural forces, to challenge the club to a cardfight on the rooftop of the school. However, instead of the Cardfight Club, Leon and Team Dreadnought appear and accept the challenge. Nonetheless, Eru Nakagami, the leader of the Research Society, engages in a Vanguard fight with Leon. Nakagami uses his Dark Irregulars deck and also unleashes his sealed paranormal powers to push for victory. Regardless, Leon defeats Nakagami by putting him in a no-win situation with Last Card, Revonn. All the while, the Cardfight Club enjoys lunch along with Takuto.
