It's time for the last leg of the VF Circuit, the Japan Stage. Taking place in an amusement park, many familiar teams have gathered. The aspect for this stage is that each team member will individually fight others in three separate stadiums. Each victory that a cardfighter gets will earn his/her team 1 point; the team with the most points by the end is the winner of the entire Japan Stage and will go on to face the previous stages' winners at the Final Stage. What's more is that "special reserve" cardfighters like Team Unknown (composed of the masked trio of King Z, Queen Y, and Joker X) will participate and act as obstacles for all of the teams. With the rules fully explained, Aichi and Q4 resolve themselves to win the Japan Stage. And so, the fights begin. Misaki and Kamui win their respective matches. On the other hand, Aichi is in a close fight in a rematch with Team Jurassic Army's Gunji Ryudo. Against the threatening Limit Break of Ryudo's new ace card, Destruction Dragon, Dark Rex, Aichi successfully defends himself, using a lot of his cards in the process. Despite the odds, Aichi stays determined and utilizes the Limit Break of his Blond Ezel twice, superior calling more units from his deck and gaining power from them, which forces Ryudo to not guard against Ezel's attack. As a result, Aichi is victorious. After saluting him on his win, Ryudo warns Aichi of what's to come in the Japan Stage. Behind the scenes, Joker X is confronted by Kyou and Team Avengers, who plot to take Team Unknown's masks and assume their roles. However, Kyou is defeated by Joker X, who reveals his true identity to Kyou and shocks him. Soon after, Kamui awaits his next opponent, who turns out to be none other than Nagisa, clad in a bridal gown and eager to marry him right now.
