As Astral recovers he is once against confronted by Number 96, who tells him he cannot win against the Barian's without accepting his evil side. As Astral refuses this and looks into the Numbers, a mysterious Giant of Shadows appears before him, saying he must be tested, summoning Yuma inside the key and challenging him to a duel. The giant quickly summons out his Xyz Monster, Unformed Void, The Fictitious King, whilst Yuma summons out Number 61: Volcasaurus and Number 6: Chronomaly Atlandis, but the giant is able to use Unformed Void's ability to counter Yuma's attack and destroy Atlandis. Number 96 appears again to remind Astral of his advice, saying that something may happen to Yuma if he loses inside the key. Fearing for Yuma's safety, Astral decides to undo the seal on Number 96, with Yuma reluctantly summoning out Dark Mist, using its abilities to defeat the giant. After the duel, Yuma and Astral are shown Astral's true memories, learning his mission is to obtain a powerful card known as Numeron Code that can shape worlds. Yuma and Astral then return to the real world while Number 96 disappears to somewhere else. (thetvdb.com)
