Parting ways with Dennis, Yuya met Shun at the [[Wonder Quartet|Ancient Ruins]]. Shun immediately asked Yuya what happened to Yuto and accused the former that he had done something to his comrade since Yuya had Yuto's "Dark Rebellion Xyz Dragon". Yuya answered that Yuto entrusted the card to him and told him to bring smiles with his Duels. Before Yuya could explain further they were interrupted by the [[Knight of Duels]] Duelists, who were Duelling each other and purposely surrounded Shun so their attack would hit him without getting penalized. Yuya, who was beside Shun, also got caught in the attack and blown away. Sora and the [[Obelisk Force]] then appeared, shocking Yuya. He called out to Sora, but he was ignored.

While Sora took Shun elsewhere to Duel, the Obelisk Force defeated the Knights of Duels and sealed them into cards, horrifying Yuya. Witnessing what had happened, Yuya had a vision of Yuto's memory when Heartland was invaded.<ref name="ep44">{{episode|Yu-Gi-Oh! ARC-V|44|ref}}</ref> Overwhelmed by the memory, Yuya succumbed to his rage and challenge the Obelisk Force. The enemies' cowardly tactics prevented Yuya from using Action Cards or avoiding their attacks. The Obelisk Force then taunted Yuya by mockingly showing the Knight of Duels' Duelists' cards and told him he will share the same fate, enraging Yuya further. As Yuto's memory filled his mind, Yuya and Yuto's soul merged again, causing him to summon "Dark Rebellion Xyz Dragon" and attack Red Obelisk Force. This started to panic the Obelisk Force and they counterattacked with their monsters until Yuya's LP reduced to 800, but despite the damage he took Yuya remained unscathed and instead smiled wickedly as he prepared for his next attack.<ref name="ep45">{{episode|Yu-Gi-Oh! ARC-V|45|ref}}</ref> On his turn with 200 LP remaining, Yuya summoned "Odd-Eyes Pendulum Dragon" and then used both "Destruction Magician" and "Creation Magician's" Pendulum effects to make "Dark Rebellion Xyz Dragon" a Level 7 monster. He overlay "Odd-Eyes Pendulum Dragon" and "Dark Rebellion Xyz Dragon" to perform a new Xyz Summon, summoning "[[Odd-Eyes Rebellion Dragon]]" and defeated the Obelisk Force in an instant. However, even after defeating the Obelisk Force, Yuya proceeded to go to where Shun and Sora were, ignoring a falling pillar that would have crushed him if not protected by Gong. Gong and Mieru took Yuya to the Jungle area where he was restrained by Gong, Michio, and Teppei while Mieru used her crystal ball to see what was inside Yuya's heart, only to find that there were two hearts inside him along with a pitch black darkness. Yuya went unconscious and later awoke without remembering his duel against the Obelisk Force. He then explained what happened to Gong and the others. Hearing Mieru's explanation about the presence of another heart inside him, Yuya realized that the other heart is none other than Yuto and his anger for what happened during Academia's invasion was what changed him. This made Yuya wondering why Yuto who entrusted him "Dark Rebellion Xyz Dragon" so he can make people smile with his duel would let him be overwhelmed by so much anger.
