S1·E9 The Shop Tournament Begins

The Card Capital Shop Tournament finally begins. In the first round, Aichi must play against Izaki while at the same time, Morikawa battles Misaki. Since this is his first time in a tournament, Aichi grows nervous. His tournament jitters get the better of him as he makes many amateur mistakes. But when he sees that Izaki is also just as nervous and makes similar mistakes, Aichi realizes that he's not alone, regains his composure, and remembers that Vanguard fights should be fun. When he tells Izaki that, he too calms down, and the two continue playing the game at their best. In the end, not only does Aichi win, but Misaki also advances to the next round.
