With both [[Vetrix]] and [[Dr. Faker]] defeated, [[Durbe]] sent [[Gilag]] to earth to acquire "[[Number]]s" since he is the bravest warrior of [[Barian World]]. Gilag appeared from a portal in front of a gang of thugs led by [[Fuma]] after Fuma mentioned wanting more power. After a scuffle, Gilag then uses "[[Rank-Up-Magic Barian's Force]]" to hypnotize Fuma and his thugs, making them chant "Barian!" With Fuma under his control, he instructed him to go after [[Yuma Tsukumo]]. Yuma then got a call from Bronk's Duel Gazer, but was shocked to find a Barian-brainwashed [[Fuma]], who told him to meet him at [[Heartland Academy]] to duel with the "[[Number]]s" at stake. Yuma gave the [[Emperor's Key]] to Tori for safekeeping and ran off to school to duel Fuma. When the Duel began, Yuma was able to gain an early lead by lowering Fuma's [[Life Point]]s to 2500, but Fuma used "[[Rank-Up-Magic Barian's Force]]" card and Summoned his CXyz Monster, "[[CXyz Mechquipped Djinn Angeneral]]", pushing him into a corner. As Yuma struggled against Fuma and "Engeneral", Yuma was about to give up since he could not think of a way to win the duel. However, after Tori showed up and returned the [[Emperor's Key]] to Yuma, he and [[Astral]] were able to make a comeback using a combination of "[[Number C39: Utopia Ray]]" and "[[Numbers Number Impact]]". Afterwards, Yuma discussed the upcoming battle against the [[Barian World]] with [[Kite]] and [[Shark]], with Yuma believing that the three of them can overcome the [[Barian]]s.

With "Master Key Beetle", [[Astral]] was able to activate the [[Different Dimension Airship]] inside the [[Emperor's Key]]. Yuma was determined to use it to go to the Barian World to save Rei. They headed out, accompanied by [[Reginald Kastle|Shark]], [[Rio Kastle|Rio]], [[Kite Tenjo|Kite]], [[Orbital 7]] and the [[Super Secret Number Cards Investigation Club]]. They were pulled out of the portal at a place called the "[[D.D. Ancient Battlefield - Sargasso]]", where [[Vector]], [[Durbe]] and [[Mizael]] awaited them. Yuma took on Vector, Kite took on Mizael, and Shark took on Durbe. Yuma, Shark, Kite, and Mizael all stated off their turns with an Xyz Summon, taking damage from "D.D. Ancient Battlefield - Sargasso". Durbe and Vector summoned their own Over-humdred Numbers, "[[Number 102: Holy Lightning - Glorious Halo]]" and "[[Number 104: Masquerade Magician - Shining]]", respectively; both of them used "[[Sargasso's Lighthouse]]" to protect themselves from the damaging effect of "Sargasso". Yuma drew "Rank-Up-Magic Limited Barian's Force" to summon "Number C39: Utopia Ray V" and used it to destroy " Shining". Vector disappeared and Yuma thought that he was killed. Just then, Rei woke up and underwent [[Bariarphose]] to reveal he was Vector in human form this entire time, and that up until now, the Vector that Yuma had dueled against was a mere illusion. During their respective Duels, Kite summoned "[[Neo Galaxy-Eyes Photon Dragon]]" and Shark used Chaos Xyz Evolution to summon "[[Number C32: Shark Drake Veiss]]". Mizael used "[[Rank-Up-Magic Barian's Force]]" to summon "[[Number C107: Neo Galaxy-Eyes Tachyon Dragon]]", and Vector used "[[Glorious NumbersNumber]]" to revive "Shining". Yuma and Astral attempted to use ZEXAL Morph, but Vector told Astral that Yuma was hiding his true identity - who knows what he's hiding from Astral? and also questioned if Astral was honestly ready to be one with Yuma. He also informed him that he would be enveloped by the sliver of darkness on his body and ZEXAL Morph failed as a result. Then, Vector reminded Astral that "Utopia Ray V" has Barian origins, which was enought for Astral to be consumed by his own darkness. Astral then forced Yuma to use [[ZEXAL_(power)|ZEXAL Morph]] with him, which resulted in them using [[ZEXAL_(power)|Dark ZEXAL]] instead.
