Episode Title:
Relentless.
Episode Description:
To take back his father who is sealed inside a card, Yuya accepts Yuri's challenge to a duel. Both Yuya and Yuto have difficulty in the duel as not only do they have to face Yuri's onslaught, they also must hold off against Zarc whose influence becomes harder to resist once Yuri summons Starving Venom Fusion Dragon and Clear Wing Synchro Dragon, while Yuya summons Odd-Eyes Pendulum Dragon. Deciding to take a risk to defeat Yuri, Yuto convinces Yuya to summon Dark Rebellion Xyz Dragon, which consequently causes Yuto to finally succumb to Zarc's control and leaves Yuya to fight Yuri alone. Unfortunately, Yuri reveals his trap card that allows him to take control of Yuto's dragon and corners Yuya further. Meanwhile, Leo has successfully activated Arc-V and starts the union of the four dimensions.
