Cardfight!! Vanguard

In the commercial center they lost they're way, but Aichi found the card shop called PSY. There, they try out the shop's special Vanguard Fight Stage. It oddly reacts to Aichi, which leads to a woman, Kourin Tatsunagi, challenging him to a cardfight. When the two begin the battle, Aichi is surprised that the stage brings the cards to life.
