For the upcoming regional Vanguard tournament, Kamui decides to have Chrono, Tokoha, and Shion form an unlikely team together. He tests their teamwork through a variety of exercises, but the trio exhibits no sign of team harmony whatsoever. Then, Kamui has the three play against Team Trinity Dragon in a special cardfight in which each team member will switch with another after each turn. Throughout the fight, Chrono, Tokoha, and Shion constantly argue with each other about their playing methods. With excellent synergy, Trinity Dragon wins, leaving Kamui to believe that there is no hope for Chrono's team. Desperate to prove Kamui wrong (although he was really faking it), Chrono, Tokoha, and Shion become determined to make their unnamed team work.
