Yuya uses the four dragons to start his counterattack against Jack. Responding to Yuya's feelings, the dragons aid Yuya in defeating Jack. Even after defeating Jack, who tells him that he is still lacking something, Yuya learns from Declan that Zarc's soul still remains inside Riley and had started to stir. After Yuya is promoted to Senior Class by Declan and is allowed to take the Professional Duelist test, Yuya requests to take the pro test right away with Declan as his opponent. Yuya once again summons the four dragons on his first turn to fight against Declan's trio of D/D/D Doom King Armageddons. Even the Tate, Fredrick and Allie are surprised they've seen those monsters before when Yuya dueled Declan the first time. He coordinates the dragons to retrieve action cards to survive Declan's attacks. The happiness Yuya felt from understanding the dragons causes him to experience one of Zarc's memories. From seeing Zarc as one of the first Dueltainers who wanted to entertain for sake of making others smile, Yuya realizes that Zarc was not truly evil at heart and his true wish is to give people happiness. Regardless, Yuya finds Declan summoning his three D/D/D Superdoom King Armageddon monsters to counter the four dragons.
