Team Q4 and friends head to the Hong Kong Stage of the VF Circuit, hoping to advance to meet with Takuto. While in front of the stadium, before the fights start, they have a short run-in with three males, one big, one normal-sized, and one small. Shin vaguely remembers seeing them before, and it is then that two identical girls appear. They tell him off by saying how that group is actually a powerful team before taking their leave.
The Hong Kong Stage officially begins. The unique attribute of this stage is that each cardfight will be 2-on-2 tag-battle style; the first team to deal 9 points of damage instead of the usual 6 to the opposing team is the victor. However, Kamui cannot comprehend the numerous difficult rules, leaving Aichi and Misaki to pair up and take on Team Lao (the group of three men who they met earlier) in the first round. Throughout the fight, the special rules are exhibited and explained: the fighters must only attack the player standing in front of them, they are forbidden to consult their partners and show the cards in their hands to one another, but they are allowed to call guardians from their hands to block for their partners and share damage for Counterblast uses. Team Lao's Terence and Felix both use Tachikaze decks; Terence's Raptor units deliver major damage to Aichi early on in the fight. Using her new Witch deck, Misaki compensates for Aichi by riding Scarlet Witch, CoCo and using various skills to draw more cards, empty her vanguard's soul, and subsequently gain benefits from it. On the sidelines, Shin finally recalls that the members of Team Lao are actually three brothers who therefore have great teamwork with each other. Can Aichi and Misaki overcome the Lao brothers' team synergy and win?
