In the midst of Yuya's duel with Barrett, Yugo and Yuri begin their duel, and summon Clear-Wing Synchro Dragon and Starve Venom Fusion Dragon. The two dragons resonate with Yuya's Odd-Eyes Pendulum Dragon and Dark Rebellion Xyz Dragon, and the three duelists enter their Berserk Modes, speaking in unison that they have "been waiting" for this moment; their revival, as they become one. As Yuri begins to approach Yugo, Yuzu arrives, and her bracelet activates, teleporting Yugo and Yuri away and breaking the connection.
With Yuzu's arrival, Barrett decides there's no need to continue the duel, especially as Yuya is still unable to play most any card, and approaches her to take her into custody. Yuya stands to defend her, and Barret chooses to honor his courage and continue the duel. Barrett attacks, Yuya's monsters not being destroyed due to his card effect's, but Yuya still takes damage and his monsters lose ATK equal to that damage. Yuya drops to 600 Life Points, and his monsters are at 0 ATK. Barrett ends his turn and invites Yuya to take his last turn and see if he has any hope.
At that moment, Sergery crashes through the room and announces his turn, taking a 2000 Life Point penalty. Watching the duel, Roget is surprised to see Yuzu there with Serena, and orders Sergey to seize them both. Sergey activates his Field Spell "Earthbound Prison" which erupts hands from the ground to keep Yuzu from fleeing. Barret is angered at Sergey interrupting their duel, but Sergey continues his turn, and swiftly performs a Synchro Summon and a Fusion Summon at once. He summons "Earthbound Disciple: Geo Griffon" and "Earthbound Disciple: Geo Kraken." Sergey destroys Barrett's monsters; as Barrett no longer controls any "Beastborg" monsters, his Traps destroy themselves, freeing Yuya from their effects. Barrett uses the effects his Fusion Monsters to revive their Fusion Materials, but Sergey uses the effect of Geo Kraken to destroy them and deal 800 damage for each of them.
Barrett is defeated, and the explosion knocks him back near Selena. He activates the teleporter function of his Duel Disk, taking them both back somewhere. Roget, furious, orders Sergey to capture Yuzu, and Yuya stands in his way. Yuya begins his turn and destroys Earthbound Prison, freeing Yuzu. The remaining Obelisk Force grunts move to take her, but Tsukikage arrives and defends her. Obelisk Force retreats, and Yuya continues his turn. With the effects of his Pendulum Monsters, he overlays Odd-Eyes and Dark Rebellion to summon "Odd-Eyes Rebellion Dragon." Yuya attacks and destroys Geo Griffon, but its effect then destroys Odd-Eyes Rebellion Dragon. Sergey declares his turn and attacks, defeating Yuya.
With the duel over, Sergey activates rocket boosters in his legs, charging through Sora and Tsukikage to seize Yuzu and flee back to Security headquarters.
This episode contains examples of:
- All Your Powers Combined: Sergey is a downplayed version, Roget created a deck that used the Academia's Fusion and the City's Synchro and gave that to Sergey.
- The Bad Guy Wins: Despite losing, Barrett manages to take Serena back to Academia with him and Sergey kidnaps Yuzu at the end of the episode.
- Big Damn Heroes: Tsukikage arrives just as the remain Obelisk Force attempt to grab Yuzu.
- Determinator: Yuya. Even when he is outnumbered and unable to do anything he refuses to give up.
- Evil Cannot Comprehend Good: Yuya destroying Sergey's field spell to free Yuzu, which could only harm Yuya gameplay-wise by halving his life points and leaving him with monsters with effects negated, is enough to throw Sergey's programming out of whack for a brief time which causes him to fail to activate his trap card in time.
- Freeze-Frame Bonus: When Barrett sends him and Serena away from the Synchro Dimension, you can briefly see on his Duel Disk interface that he is not pressing on the Academia button, but on the Xyz Dimension button.
- Madness Mantra: The four Yu's keep saying one over and over again as they prepare to fuse.
- Pet the Dog: Barrett vows to free Yuzu from Sergey and let Yuya see her... at least before he then reminds Yuya he'll be taking Yuzu immediately after. Still, it's more consideration than anyone else has given so far.
- Screw This, I'm Out of Here!: The remaining Obelisk Force decided to retreat after both Yuri and Barrett are gone and they are vastly outnumbered.
- Ship Tease: The episode was overflowing with Yuya and Yuzu ship tease.
- Villainous Rescue: Sergey's arrival pretty much prevents Yuya from losing to Barrett without a fight. Then subverted when his arrival just makes things worse even if it did allow Yuya to keep dueling.
- Wham Line:
- The four Yus saying "We shall become one!"
- The four Yu's also saying "The time of our revival"
- The Worf Effect: After being able to duel Reiji competently last season and completely immobilizing Yuya here, Barrett is crushed in one turn to demonstrate the power of Sergey's Earthbound deck.
- Worthy Opponent: Barrett acknowledges Yuya as one, due to his determination to protect his comrades even when he's chained up and unable to do anything.
