Season 4

In just six months, Uniformers have changed the very concept of Vanguard, but no one knows their real identity. Can these mysterious players be defeated?

What happens if you place a Hollowing Moonlit Night in the Order Zone and draw a card? Let’s find out!

Megumi learns more about Halona and her connection to Gui when she’s scouted by the Uniformers.

Haruka left because she believed she was holding Mirei back. But she didn’t consider Mirei’s thoughts on the matter.

Megumi always felt she had to catch up to Danji, but no longer. She’s grown stronger now and Danji will have to pull out all the stops if he wants to defeat her.

Not everyone agrees with the Uniformers, but if they wish to challenge the group on an equal playing field, they must all grow stronger.

AI Gui rejects Jinki's proposal and starts to make moves beyond their expectations. If they have taken the wrong path, they must correct it. Jinki challenges Gui to a duel as his foster parent, carrying the deck used by his older brother, Shingi, the inventor.

Masanori, who has skillfully evaded Tohya's challenges, finally faces him in a destined showdown on Mt. Yama. Masanori controls the Zorga Masques Deck, while Tohya unleashes a new Bastion Deck, determined to secure victory.

Danji presents a challenge to the Uniformers. In response, AI Gui sets up a stage at the sacred ground of Kaganokuni, Hakusan, to determine the future of Vanguard. In the first match, Shirogane stands before Yu-yu, once their comrade, Zakusa.

The second match at the foot of Hakusan. Urara's opponent is Halona, whose fighting spirit is ablaze. Halona aims to defeat Urara and prove that the Uniformers are right. Urara wants to win against Halona and become friends once again. The clash of their determination and emotions ensues.

The final match at the foot of Hakusan. Sophie vs Raika, entrusted with their fateful showdown. Genius vs prodigy, witch vs nobleman, Starry Skies vs Sky Fall. The fight between these two contrasting individuals takes an unexpected turn when Sophie unleashes her full power.

The final battle at the foot of Hakusan. AI Gui, who fights Yu-yu, aims not only for a complete victory but also for the last piece of data to realize the ultimate battle that developer Shingi aspired to. And now, the true power of Gui's Dragontree Deck begins to awaken.

The overwhelming strength of Dragontree. For AI Gui, Yu-yu is merely the last fighter to analyze. He claims that the bond with the cards is just noise and that Vanguard does not require individuality. What move does Yu-yu, who surpasses Gui, make? And what will the outcome of the match be?
