Aichi VS Kamui - S1.E12

It's the semifinals: Kai plays against Misaki, and Aichi once again battles Kamui. Both Aichi and Kamui want to win for their own reasons; Aichi wants to fight Kai again while Kamui hopes to gain Emi's affection upon winning the entire tournament. Aichi defends himself from Kamui's Genocide Jack's attacks better than he did in their first cardfight. Aichi makes a surprising move by calling Blaster Blade as a rear-guard and using its ability to destroy Genocide Jack. As the battle between Aichi and Kamui rages on, the cardfight between Kai and Misaki comes to a close with Kai as the victor.
