As the [[Duel]] continues, Quattro proceeded to Rank-Up "[[Number 88: Gimmick Puppet of Leo (anime)|Number 88: Gimmick Puppet of Leo]]" into "[[Number C88: Gimmick Puppet Disaster Leo (anime)|Number C88: Gimmick Puppet Disaster Leo]]", but Nash countered its [[Automatic Win]] condition by attaching an Overlay Unit from "Silent Honor DARK" to it via "[[Overlay Award]]". Using "[[Cross Draw of Destiny]]", Nasch Nash Summoned "[[Silent Wobby (anime)|Silent Wobby]]" to Quattro's field and absorbed it with "Silent Honor DARK", defeating Quattro with a boost from "[[Power Stream]]". As Quattro was sent to the Barian World, he remarked he'd be going to hell before Nash, who responded that he'd be joining Quattro there as soon as the conflict was over. The other Emperors regrouped and Nasch Nash ordered them to split and find the remaining "Number" holders - Yuma, Astral, Kite, [[Trey]] and [[Quinton]]. Meanwhile, Yuma regains consciousness and learns what happened to his friends.[[File:Mizar confronts Quinton and Trey.png|thumb|200px|right|Trey and Quinton prepare to face off against [[Mizar]].]] As Yuma tries to think of a way to stop the Barians without fighting his friend (Nash), [[Kite Tenjo|Kite]] states that "Shark" was now their enemy and they could not avoid a fight now. Yuma insisted they couldn't fight their friend, but Kite pointed out that Quattro was dead because of him and he was their friend too. Astral suggests that they may be able to return them to normal if they defeat [[Don Thousand]]. However, Kite told them he couldn't go and that he had something to do departing on Orbital's motorcycle form, while Trey and Quinton become determined to avenge Quattro. With Yuma and Astral preparing to head off to Barian World alone, Cathy encourages Tori to go with them, while Trey and Quinton prepare to face off against [[Mizar]].

As Mizar takes on both Trey and Quinton at once, [[Vector]] uses the separation of the Barian Emperors to put [[Alito]] and [[Girag]] under Don Thousand's control, as part of his plan to usurp Nash, even when Alito calls Vector a fool for reviving Don Thousand. Meanwhile, [[Caswell Francis|Caswell]] and [[Cathy Katherine|Cathy]] tell Yuma's family where he has gone. Meanwhile back with Quinton, he informed Mizar that he was the one who had taught [[Kite Tenjo|Kite]] how to Duel, which seemed to intrigue Mizar. The Duel began and Quinton immediately brings out "Number 9: Dyson Sphere". The immense monster's presence warning [[Dumon]] and [[Rio Kastle|Marin]] to the Duel's start and they quickly joined Mizar, who told them he was fine and to go search for Yuma and Kite. Quinton and Trey used the power of their bracelets' [[Crest|crest]]s to generate a [[Sphere Field]], trapping the three [[Barian]]s. Mizar summons "Number 107: Galaxy-Eyes Tachyon Dragon" and destroys "Dyson Sphere". In their respective whereabouts, Kite and Yuma dwell on Trey and Quinton's situation. Meanwhile, Girag alerts Nasch Nash to Yuma's exodus in order to trick him, and Nash promptly returns to Barian World to pursue him. Back to the Duel, Trey summons "Atlandis" and attempts to use "Dyson Sphere" to gain its ATK, but Mizar uses a trap to negate this effect. But the brothers have planned for this, and use "[[Rank-Up-Magic Argent Chaos Force (anime)|Rank-Up-Magic Argent Chaos Force]]", ranking "Atlandis" up to "Chaos Number 6: Chronomaly Chaos Atlandis" and attacking "Tachyon Dragon". Mizar's trap is destroyed to preserve "Tachyon Dragon", allowing Trey to equip "Tachyon Dragon" to "Chaos Atlandis". Mizar called this the first time he had been humiliated and used [[Barian's Chaos Draw]] to draw "[[Rank-Up-Magic - The Seventh One (anime)|The Seventh One]]". He intended to [[Rank-Up]] "Tachyon Dragon", but quickly realized he could not, as it was not on his field or in his Graveyard or Extra Deck, but equipped to his opponent's monster.

Admitting he had underestimated them, Mizar played defensively using "[[Heliosphere Dragon (anime)|Heliosphere Dragon]]" and two [[Trap Cards]]. This was enough to survive Quinton's combo of "Chaos Atlandis" and "[[Number C9: Chaos Dyson Sphere (anime)|Number C9: Chaos Dyson Sphere]]", though his Life Points remained at only 1. Mizar also recovered "Tachyon Dragon" this way, enabling him to summon "Neo Tachyon". The brothers attempted a counter with "[[Monopole Chain]]" and "[[Atlandis Invitation]]", but the effect of "Neo Tachyon" rewound time and rendered them useless. [[File:GiragCapturesNash.png|thumb|left|[[Girag]] captures [[Nash]].]]Meanwhile, [[Girag]] captures Nasch Nash during their travel and brings him to Don Thousand, saying that he couldn't allow Nash to duel Yuma, "in the name of Don Thousand." Before their defeat, Quinton activated a communications link with Yuma and told both him and Mizar where Kite had gone. He had discovered [[Legend of the Dragons of Light and Time|tablet detailing a legend]] regarding the "[[Galaxy-Eyes]]" dragons. Believing them connected to the [[Numeron Code]], he journeyed to the moon. Quinton told Yuma to remember the end of this Duel as a warning at how powerful the [[Seven Barian Emperors]] could be. As Yuma sobs, Mizar orders his direct attack. [[File:Duel_observation.png|thumb|[[Orbital 7]] status of [[Quinton]] and [[Trey]].]]As they were defeated, they told Yuma they'd always be with him in spirit. The Sphere Field encasing the Duel's area fades as the souls of Quinton and Trey stream towards the Barian World and Mizar sends them off, saying "farewell, proud brothers." Vector vanishes through a portal, grinning. Kite's "[[Galaxy-Eyes Photon Dragon (anime)|Photon Dragon]]" card glows as he nears the moon. Mizar sees his own "[[Number 107: Galaxy-Eyes Tachyon Dragon (anime)|Tachyon Dragon]]" card is also glowing. Dumon asks if Mizar plans to go to the moon, with Mizar responding that his greatest enemy waits there.

When they were resuscitated, they find themselves in a small room surrounded by pillars, while [[Baria Crystal|Baria]] and [[AstriteAstralite]] crystals floated around. Before them is a winding staircase, which leads straight into the Astral World, the [[Astral Tower]] visible. Yuma says it cannot be. Turning, Yuma observes another staircase leading to Earth - which is still fused with the Barian World. Yuma questions what is going on - they should have protected the world by defeating Thousand. Nash appears behind them in human form, saying that Earth and the Barian World are still merged - and they are currently in a small location between that merged world and the Astral World. Yuma mutters "Shark..." Nash explains that right now, the two worlds are pulling against one another. If it keeps up, the two worlds will collide, resulting in the Astral World's destruction.

Nash weakened "Utopia" with "[[Friller Rabca (anime)|Friller Rabca]]" and brought out "[[Submersible Carrier Aero Shark (anime)|Submersible Carrier Aero Shark]]" as well, but Yuma survived with "[[Damage Take-Over]]". Using ZEXAL, Yuma and Astral created "[[ZW - Sylphid Wing]]", but Nash revived "Barian Hope" using "[[Rebirth of the Seven Emperors]]" at the expense of his Rank 3 monsters. Yuma pushed the attack, but Nash used "[[Draw of Fate (anime)|Draw of Fate]]" to negate the attack and force both players to draw a card. If the player did not use the drawn card by the end of this turn, they would [[Victory Condition|automatically lose]]. Nash used Barian's Chaos Draw to draw "[[Glory of the Seven Emperors]]", while Yuma used Shining Draw to draw "Double or Nothing!" Yuma canceled his attack after activating "Double or Nothing!", knowing that defeating Nash would be to sacrifice Yuma's rapport for his enemies, just as [[the Door]] had predicted.
