The revived Zarc begins his attack on the Fusion Dimension. While Declan and Riley go to confront Leo after Riley heard Ray's plea to be revived, Aster and Sora challenge Zarc to a duel. Believing that Yuya still exists despite Zarc saying otherwise, Aster and Sora unleash their attacks while calling out for Yuya to return. Despite their best efforts, their words do not reach Yuya nor can they land a scratch on Zarc who quickly overwhelms them by performing an Integration Summon. Zarc fuses himself with the Four Heavenly Dragons to summon Supreme King Z-ARC and defeats Aster and Sora. Shay and Kite join the duel afterwards, and they are both determined to carry out Aster and Sora's feelings to save Yuya.
