As Astral tells Yuma about the contraption inside his key, Kite learns that Yuma's key is not from this world and decides to obtain it for himself. He sends his robot, Orbital-7, to steal Yuma's key while he is swimming, but Shark stands in his way. Believing he possesses a Numbers card, Kite appears and challenges Shark to a duel. As Kite summons one of his Numbers, Number 30: Acid Golem of Destruction, Shark takes control of it, only to fall prey to its hidden effects. Kite defeats Shark, taking both his soul and Yuma's key, with Astral still inside it, even while Yuma and his friends arrive on the scene.
