Yuma and Tori arrive at the Magma Field where Shark and Quattro have begun their duel. Shark summons his Aero Shark whilst Quattro defeats it with his Giant Grinder. Just then, Shark summons the Number card he got from Trey, Shark Drake, and defeats Giant Grinder. Just then, Vetrix appears, revealing his plan, which included having Quattro push Shark into a trap and hurt his sister, is for the sake of pushing Shark heart's into darkness so he can be controlled into taking down Faker. Not willing to accept that he is not chosen to take down Faker, Quattro summons Number 40: Gimmick Puppet of Strings, using it to repeatedly attack Shark while Yuma stands helpless, taunted by Vetrix.
