Allen and Saya reveal to Yuya that Shay went to the Fusion Dimension to search for Lulu. Dennis refuses to allow Yuya to leave until he defeats him in a duel. As the duel commences, Dennis summons his Fusion monsters while threatening the Heartland citizens that he will turn them into cards again if they leave. Aster explains that the citizens of Heartland are severely traumatized by Duel Academy's invasion to the point that they rejected dueling itself. Dennis presents himself as a villain as he and Aster hope Yuya might help restore the peoples' love for dueling. Realizing Dennis' goal, the two start their Dueltainment as Dennis disposes his bad guy act. Using the combination of his permanent spell cards and Odd-Eyes Pendulum Dragon, Yuya defeats Dennis and successfully restores the citizens' love for dueling. Entrusting Dennis to teach the children of Heartland City Dueltaining, Yuya leaves for the Fusion Dimension to duel Shay.
