A new student named Rei Shingetsu transfers into Yuma's class and becomes a devoted fan after Yuma won the WDC. The school is excited about Pro Duelist Daisuke Katagiri arriving for a special lesson, but Yuma is banned from attending. Feeling sympathetic toward Yuma, Rei leaves to obtain Daisuke's signature. Instead of a simple autograph, Rei encounters a coaching session orchestrated by Daisuke, who is currently under the control of the Barian faction. This unexpected encounter places Rei in a dangerous situation as he interacts with the mind-controlled duelist, leading to unforeseen consequences for the new student who only intended to help his idol.
