The Weed Soul!
Q4 makes it to the semifinals of the Hong Kong Stage with Aichi and Misaki doing all of the cardfighting. After diligently studying the tag fight rules, Kamui offers to participate in the next fight. So, it is decided that Kamui and Misaki will pair up for their fight against Team Battle Weeds, a group of three kids who greatly admire the tenacity of weeds. True to their namesake, the members of Battle Weeds use Neo Nectar decks. Withstanding the Limit Break of Battle Weeds' ace card, White Lily Musketeer, Cecilia, Kamui proceeds to ride his new key card, Perfect Raizer. Its skill increases its power to exponential heights, and managing to pull a critical trigger, Kamui wins the match for Q4, thus advancing the team to the finals. However, Q4's next opponent is Team Dreadnought, with its members consisting of the two previously-encountered twin sisters, Jillian and Sharlene, and their leader, Leon Souryu.

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.
