Es ist kein einfacher Streich unter Schülern, als Yuma und Ray plötzlich in die Enge getrieben werden. Die Attackierenden stehen unter dem Einfuss der Barian-Welt – sie haben es auf Yumas Nummernkarten abgesehen! Shark, Rio und Tori wollen ihm helfen, doch letztlich liegt es an Yuma selbst, diesen Angriff in einem Duell abzuwehren …
As Yuma and Ray make their way to school, they are pursued by a group of Barian-possessed students and are forced to run. They become cornered, but are assisted by the arrival of Shark, Tori and Rio, who help Yuma fight off the forces of Barian World. Just then, Alito arrives and protects Yuma, defeating all the other students in the process, as he wanted to battle Yuma fair and square. With his alliance to Barian World revealed, Alito challenges Yuma to a duel, activating a Sphere Field along with it. Alito instantly summons Battlin' Boxer Lead Yoke while Yuma summons out Utopia, and the two engage in a battle of counter traps. Yuma eventually manages to destroy Lead Yoke by countering its ability. As Yuma and Alito become excited by the duel, Astral detects something amiss with the Sphere Field.
