Misaki and Kamui await for Kenji to return from his travels at an airport, hoping to get information from him about Gaillard and Neve. While waiting, Misaki and Kamui help a lost foreign girl by buying her doughnuts. They eventually meet up with Kenji and another man named Raul Cera while also learning that the girl's name is Ratie Curti. Misaki and Kamui try to ask Kenji about Gaillard and Neve, but before he can answer, Ratie insists on having a cardfight with him. And so, Kenji and Ratie cardfight while Misaki, Kamui, Cera, and a growing number of spectators watch. As Ratie exhibits her Shadow Paladin Witch deck's abilities to replace some of Kenji's rear-guards with weaker ones, a spectator comments on how both she and Cera are world-class cardfighters, which lead Misaki and Kamui to believe that they may be connected to Gaillard and Neve. When Ratie deals 5 damage to Kenji, Cera leaves after thinking Ratie has already won, which prompts Kamui to follow him. Kenji tries to mount a comeback with Ultimate Dimensional Robo, Great Daikaiser and its Limit Break to gain an additional drive check, but Ratie protects herself and then wins the match with a Legion attack. After Kenji briefly steps out to take a phone call, Ratie and Cera reveal themselves as Quatre Knights to Misaki and Kamui. They create their respective fight fields to trap Misaki and Kamui, who prepare themselves for battle.
