Depressed about losing his Royal Paladin deck, Aichi meets Kai. He learns that not only has Kai's deck been changed to a Narukami deck, but also that Kai has no memory of using a Kagero deck or of Aichi using Royal Paladins. To find some answers, the two have a cardfight. As Aichi struggles to get comfortable with his new Gold Paladin deck, Kai slowly realizes that something is off. Getting his memory back, Kai nonetheless chooses to continue using his current deck, but Aichi is conflicted about using his. Kai tells Aichi that he is bound by his own limits by not wanting to use Gold Paladins and that he needs to break through them. To prove his point, Kai rides Dragonic Kaiser Vermillion, declares "Final Turn", and performs Limit Break, an ability that activates when a player has 4 or more damage. With Vermillion's Limit Break, Kai attacks all of Aichi's front-row units in one strike and wins as a result. After the battle, Aichi and Kai watch a commercial advertising the Vanguard Fight Circuit, a worldwide invitational tournament which is sponsored by Takuto Tatsunagi, the young boy that Aichi met before and the one responsible for the phenomena of changing their decks. To use the VF Circuit as a way to reach Takuto, Aichi and Kai go their separate paths. When Aichi goes to Card Capital, he is surprised to learn that Team Q4 has received an invitation to the VF Circuit.
