Auf dem Weg zur letzten Kontrolleinheit müssen sich Akiza und Mina trennen, um die versteckte Misty auf einem verlassenen Rummelplatz zu suchen. Letztendlich findet Akiza Misty in einem Spiellabyrinth. Akiza stellt sich einem Duell gegen die verärgerte Misty. Schnell wird der Grund für Mistys Wut und Zorn offengelegt. Unterdessen wird Mina von einem Fremden in eine Falle gelockt.
Akiza and Mina arrive at an abandoned amusement park where Ccarayhua's control unit is, shortly followed by Yusei's group, and a man claiming to be sent by Goodwin. Misty traps Akiza in a Hall of Mirrors, actually dueling her through the mirrors. She uses cards that block off drawing cards from the deck, and also shows Akiza the events involving Misty and her brother, Toby, who apparently met her at Arcadia Movement.
Yusei is led to a room where Mina is found unconscious and is attacked by the man who turns out to be Sayer, who had survived his duel with Carly, and is determined to reclaim Akiza. He uses his psychic abilities to knock Yusei in a cage with Mina as it slowly fills with water. Trudge eventually finds them and tries to free them. Akiza is shown the moment where Toby was killed, which led Misty to become depressed and crash her car, transforming her into a Dark Signer. Akiza refuses to fight back and almost falls on a shard of glass, but is saved by Sayer, who whispers something in Akiza's ear that causes her to reawaken her dormant physic powers and summons Black Rose Dragon, which shatters all the mirrors, destroying the illusion, which reveals Misty's real location.
Akiza affronte Misty à la Tour du Lézard. Pendant ce temps, Sawer, qui a survécu à la destruction du Mouvement Arcadie, utilise ses pouvoirs psychiques pour contrôler Akiza et lui faire battre Misty.
