Chrono, Tokoha, and Shion enter in a U20-qualifying tournament with their respective teams. In this tournament, players are randomly paired up, and the team with the most collective victories will get a guaranteed spot into the U20. As the tournament progresses, Kazuma eventually fights Mamoru. Believing to be on the verge of losing to Mamoru, Kazuma decides to quit before the fight properly concludes, which angers Chrono. He tries to ask Kazuma about his pessimism and convince him to just try, but this leads to a small fight between the two, ending with Kazuma leaving. At the end of the tournament, Shion's team is declared the winner, and Mamoru informs Chrono about thugs who are using Vanguard to attack people.
