Aichi is feeling desperate by the fact that he and Q4 must win the Japan Stage of the VF Circuit. To better prepare the team, Shin recommends for Aichi, Kamui, and Misaki to battle against other stronger, non-Q4-affiliated cardfighters. Aichi takes a look at his Blond Ezel card and is reminded about Kourin, the person who gave it to him. So, Q4 goes to Card Shop PSY and requests for the Ultra Rare girls to cardfight with them for training purposes. They accept, and thus the battles ensue. The first match-up is between Aichi and Kourin, who now uses an Angel Feather deck. Aichi gains the upper hand when he superior rides Pellinore, but Kourin uses her Angel Feathers' skills to swap cards from her damage zone and then calling them. As the fight continues, Kourin antagonistically puts down Aichi by telling him to give up and how he's reached his limits. He proves her wrong and shows his determination when he rides Blond Ezel and activates its Limit Break to defeat her.
