Card Capital is holding a casual shop tournament. Aichi, Kamui, and Misaki enter in the senior division, while Emi competes in the junior division. Morikawa also wants to enter, but he unfortunately has left his "super-strong" deck at home. So, Shin lends Morikawa an unmodified trial deck to use. The deck does not have as many grade 3 units as Morikawa would like, leading him to believe the deck is weak. Nevertheless, to everyone's surprise, Morikawa goes on a winning streak with this seemingly "weak" deck, even beating Aichi, who no longer cares about winning but instead is reminded about just having fun.
