Yuma comes across Ray facing off against a Barian emmissary named Vector, who flees when Yuma arrives on the scene. Ray warns Yuma about Vector, giving Yuma some more Barian cards, reminding him not to tell Astral about them. The next day, Vector appears before Yuma and Astral and forces them to duel him, revealing himself to be the Barian emissary that possessed Dr. Faker. Vector summons out Number 66: Master Key Beetle and seals away Yuma's Limited Barian's Force card. Yuma summons out Utopia and manages to destroy Master Key Beetle and recover his card, but Vector manages to revive it, recover his life points and summon tokens to destroy Utopia. As Ray arrives to give Yuma support, Yuma uses one of the cards he received from Ray, V Salamander, to revive Utopia and evolve it into Utopia Ray V, using V Salamander's effects to defeat Vector. Just then, Vector captures Ray and takes him to the Barian World, leaving Astral with Number 66: Master Key Beetle, which Vector said is the key to their final battle.
