Team 5D's prepare to face up against Team Catastrophe, the leader of which, Nicholas, has been given a Card of Darkness by Primo. Team 5D's are later visited by Breo, and study the memory chips of Jean and Andre's Duel Runners, revealing something had caused their wheels to suddenly lock up and crash, the same reason why Crow crashed. After studying a video Carly gave them, the Signers believe it to be linked to a monster called Hidden Knight Hook. Akiza gets hit by the same phenomenon, and her psychic powers fail, as she loses it, to save her from getting injured. (And, Akiza's psychic powers don't return until Episode 140, after the Ark Cradle appears.) Despite his arm not being fully healed, Crow decides to take her place in their match against Team Catastrophe. The first round sees Crow against Hermann, who instantly summons Hidden Knight Hook. As it uses its effect against Crow's attack, Crow notices a strange hook aim for his wheel and barely manages to avoid it.
