Gauche is part of the Team Duel Tournament's committee. In order to enter the tournament, a member of the Dueling Team should face Gauche in a Duel, and if he judged the team was worthy, then it would enter. Yuma faces Gauche representing the Team ZEXAL, and by defeating him, makes his team able to enter the tournament.
Gauche later shows up again to announce the beginning of the tournament and explain the rules. He also announces news about the tournament, like when Team Shark became the first team to advance to the finals.
