Meanwhile, Yuya, shocked after seeing the Obelisk Force turn the Knights of the Duel Disks into cards, once again becomes possessed by Yuto's dark side and challenges the Obelisk Force. After Celina beats Dennis who did not want to use Xyz monsters and cause a misunderstanding, she and Zuzu are approached by the Obelisk Force, but they are aided by the arrival of Declan's team of Senior duelists. Meanwhile, Yuya brings out Dark Rebellion Xyz Dragon against the Obelisk Force, just as Gong and Aura come across him.
