After a brief encounter with Sylvio, who informs Yuya and Zuzu of another attack by an Xyz user, Yuya realizes that in order to become a pro duelist he needs to increase his winning percentage in order to qualify for the Junior Arc League Championship. However, Yuya struggles to find four other duelists willing to duel against him and refuses to ask Gong for help. He wants to become a pro with his own strength. The Sledgehammer's former manager, Nico Smiley, offers to give Yuya automatic entry into the championship, but Yuya once again refuses. He instead asks Nico to find four opponents to fight against him fairly. Meanwhile, as Julia, Kit, and Dipper try to investigate what happened to Marco, Zuzu asks Sora to teach her Fusion Summoning so she can grow stronger against Julia. The mysterious Xyz user appears before them, but before either Sora or Julia can duel against him, Zuzu's bracelet glows again and the duelist vanishes. As Yuya appeared, Julia accused him for siding with the mysterious duelist. As Zuzu attempted to calm Julia down, Sora managed to fool her by telling where the mysterious duelist went. Another unknown figure appears outside the LID building presumably beginning for an attack.
