Having noticed that Kourin has also disappeared like Aichi, Kai goes to Card Shop PSY to look for possible clues. There, he meets Olivier Gaillard, the champion of the Vanguard European Circuit. When Gaillard states he knows Aichi, Kai assumes he is an ally. However, Gaillard reveals that he is one of the Quatre Knights and tells Kai to stop his search for Aichi, but he refuses. Gaillard uses his mystical powers to create a separate dimension surrounded by blue flames called the Holy Prominence Prison in which he and Kai cardfight. Kai is surprised to see Gaillard using Aichi's Gold Paladin deck, and Gaillard responds by saying he has inherited Aichi's will. Despite Kai's best efforts, Gaillard defeats him, which causes the prison to inflict direct damage to Kai. Although he survives, Gaillard is confident that he has instilled fear deep in Kai's heart. Gaillard also tells Kai that he and the other three Quatre Knights will continue to attack Kai and his mates to stop them from finding Aichi, who has fallen into a deep slumber. After Gaillard leaves, Kai tries to go warn everyone but then faints...
