Challenge from PSY
With Team Q4 reunited, Aichi, Kamui, and Misaki go shopping in preparation for the VF Circuit. After they finish their shopping, they visit Card Shop PSY so that Aichi can talk to Suiko about the mystery behind the replacement of his Royal Paladin deck. Once there, they find out that the Ultra Rare girls will also be going overseas. Noticing the large amount of shopping bags that Team Q4 has, Rekka questions the team's motive for participating in the VF Circuit. When Misaki says that she's going because she was asked to, Rekka insults her for treating their ticket to the VF Circuit as a free vacation and having no intention to win. To prove her wrong, Misaki challenges Rekka to a cardfight. While using the new Angel Feather clan to use cards in her damage zone to her advantage, Rekka criticizes Misaki's deck for being good but still lacking. Rekka then shows Misaki what that missing attribute is when she rides Circular Saw, Kiriel and utilizes its Limit Break to defeat her. Through this loss, Team Q4 realizes that they must change their mentality and their decks if they want to have a chance to win the VF Circuit.

Cardfight!! Vanguard Asia Circuit
Aichi and his friends have won the National Tournament and decide to go their own ways until a mysterious boy named Takuto Tatsunagi appears. He reveals that the Royal Paladins, Shadow Paladins, and Kagero leaders have been captured, and the only way to free Cray is for the Vanguard fighters to use a new power- Limit Break. Because the Royal Paladins lose the ability to fight, Aichi's deck is changed to be a Gold Paladin deck. Aichi and his friends must now win the Vanguard VF Circuit if they are to learn more about the occurrences on Cray and free their old friends.
