Ep. 7: Kai advierte a sus amigos mientras Naoki pierde un duelo de cartas contra Phillip Neve en la Escuela Secundaria Hitsue.

7

Kai regains consciousness and tries to go warn his friends about the Quatre Knights. Meanwhile, Misaki and Naoki are walking through a park where they discover a man playing with a few cats, including the Assista-cat. The man reveals himself as Phillip Neve, one of the Quatre Knights who wants to stop them from finding Aichi. Refusing to fight Misaki, Neve accepts Naoki's challenge. Like Gaillard, Neve creates a field called the Steel Wall Prison in which he and Naoki cardfight. Naoki gains the upper hand after using Legion with Brawler, Big Bang Knuckle Dragon and Big Bang Slash Dragon while destroying almost all of Neve's rear-guards, but Neve is unimpressed. He responds by performing his own Legion with Metal Borg, Sin Buster and Uru Buster while preventing Naoki from using a perfect guard to nullify the Legion attack, resulting in Naoki's defeat and causing the prison to inflict direct damage to him. Then, Misaki tries to challenge Neve, but Kai arrives and tells her to not do it. After Neve leaves, Kai, Misaki, and Naoki go to Hitsue High School and find Miwa, who is wounded after being attacked by another Quatre Knight. (Source: Wikipedia)
