The Fate of Three Worlds.Yuma attacks Numerronius Numerronia with Utopia, after using both Abyss' and Numeron Dragon's abilities to boost Utopia's attack points to 102,000 points. However, Don Thousand uses Numerronius Numerronia's ability to negate the attack and boost his life points to 102,900. But then, Yuma uses Double or Nothing to double Utopia's attack points to 204,000 points, which also allows it to attack again, finally destroying Numerronius Numerronia and defeating Don Thousand. Kite's spirit disappears as Yuma thanks him for his help. The portal to Astral World closes, and the fusion between Barian World and the Human World appears to be undone. However, Don Thousand gloats that they had destroyed only his body and that the fight wasn't over yet. With his final breath, Don Thousand transfers his soul into Nash, along with the souls of the other Barian Emperors, and all of his Number cards, which are infused with Don Thousand's malignant essence. Nash becomes covered in an evil aura, and he forces Yuma and Astral out of the ZEXAL III fusion, and sends all of them to an arena between Astral World and Barian World. It is then revealed that Human World and Barian World are still fused together, and that both worlds were beginning to merge with Astral World. Additionally, the suns of all 3 worlds appear in the sky above them...
