Vektor erkennt, dass er die Verbindung zwischen Yuma und Astral kappen muss, um das Duell zu gewinnen. Doch kann er wirklich einen Keil zwischen die beiden Freunde treiben?
Yuma continues to be put under pressure by Vector as he decreases his deck size even further and revives Masquerade. Meanwhile, Shark and Kite summon Shark Drake Veiss and Neo Galaxy-Eyes Photon Dragon respectively, while Mizar uses Barian's Force to summon Chaos Number 107: Neo Galaxy-Eyes Tachyon Dragon. Just then, a black hole appears, threatening to swallow up the spaceship with Tori and the others inside. Vector suggests that Yuma may be able to save them if he relinquishes all of his Numbers. As Yuma becomes conflicted between saving Astral and saving his friends, Tori urges him to keep dueling, while Orbital 7 arrives to assist them in getting the ship to safety. Yuma and Astral attempts to perform a ZEXAL fusion, but it fails due to the small crack of distrust left in Astral due to Yuma using Barian cards and him keeping secrets from Astral. Astral is suddenly swallowed by darkness and forces Yuma to fuse with him, resulting in Dark ZEXAL.
