Arrival
Stumbled in the destroyed Heartland, Yūya, Shingo, and Gongenzaka separated themselves with Shun who was looking for any member of Resistance left while the three of them look for Yuzu and tried to contact her through their Duel Disk, but there was no answer. They met some refugees who explained that they haven't seen any member of the Resistance recently and presumed that they all have been wiped out. Three Academia Duelists then found them and challenged the Lancers to a Duel.

Duel Against Kaito
The Academia Duelists were defeated and attempted to flee, but they were carded by a Resistance Duelist, Kaito Tenjō. Mistaking the Lancers as Duelists of Academia, Kaito challenged them to a Duel, which accepted by Shingo. Gongenzaka also joined the Duel in attempt to stop the two. Yūto, who was inside Yūya, started to communicate with Yūya and revealed Kaito's background as ace student from Heartland Duel School's Clover branch while Yūto, Shun, and Ruri were from Spade branch. He that Kaito's Dueling used to be subtle yet dynamic, which was a total opposite of the current Kaito who only filled with anger. Kaito defeated Shingo and Gongenzaka, so Yūya decided to clear the misunderstanding with Kaito through Duel. The strategy that Yūya used was correctly done, but Kaito was able to deduce his step and launched his own counterattacks, even destroying Yūya's strongest monster, "Odd-Eyes Rebellion Dragon". Yūto assisted Yūya by summoning "Dark Rebellion Xyz Dragon", a monster that Kaito recognized as Yūto's ace monster and thought for a moment that Yūya stole it until he saw a glimpse of Yūto within Yūya. The Duel was stopped by Shun's arrival with his two comrades, Allen Kōzuki and Sayaka Sasayama. Despite Shun's assurance that Yūya and the others are his allies, Kaito refused to return to the Resistance and left.

Resistance Hideout
At the Resistance's hideout, as they introduced each other, Allen and Sayaka revealed that while Shun and Yūto were gone, Academia had launched a large-scale attack that defeated the majority of their Duelists and civilians, forcing them to went into hiding in Duel Lodge. Kaito's family is one of the victims, which became the reason why Kaito left the Resistance and act on his own. They also learned that Yūya's father, Yūshō Sakaki, was a teacher of the Clover branch. However, Yūshō one day suddenly disappeared and Allen believed that Yūshō has abandoned them and ran away on his own.

Yuzu's Arrival in Fusion Dimension
Meanwhile, Yuzu ended up at Fusion Dimension and was chased by three Academia Juvenile Officers after being mistaken as a runaway student. Cornered, Yuzu was prepared to Duel the officers, but before she could do so, she was saved by a former Academia student disguised as a gondolier, Asuka Tenjōin. After defeating the three Academia Duelists, Asuka took Yuzu to an underground Duel School independent from Academia, You Show Duel School, that turned out to be led by Yūshō. As Yuzu questioned how and why he was at Fusion Dimension, Yūshō explained to Yuzu that three years ago, he learned from Reiji that Leo intends to conquer the whole dimensions, so he forcefully made his way into Leo Corporation's lab to use the prototype of dimension travel device to go to Fusion Dimension and convince Leo. But instead of Fusion Dimension, he ended up at Xyz Dimension and stayed there until Academia invaded. He met the Commander-in-Chief of Academia stationed in Heartland, Edo Phoenix, and got sent into Fusion Dimension by him after Dueling him.

Duel Against Edo
Back at the Xyz Dimension, Edo was holding a torn "Smile World" while looking for Yūshō. At the same time, Yūya also went to look for his father, refusing to believe that Yūshō was running away like Allen believed him to be. While looking for his father, Yūya and Yūto discussed their current condition of sharing one body and the phenomenon that happened before during his Duel against Barrett. Both sensed there was unknown being inside them that overwhelmed them with great power and deduced that was most likely the cause of their current condition. They were interrupted when Edo, in disguise, questioned Yūya's presence on the site and asked for Yūya's father's name, offering to help looking for his father. Hearing that Yūya is Yūshō's son, Edo challenged him to a Duel, intending to capture Yūya and use him as a bait to lure out Yūshō. As Yūya was having a hard time against Edo, Yūto, who regretted for leaving his homeland and enraged at Academia for carding many of his comrades, forcefully possessed Yūya's body and took over the Duel, cornering Edo with his Rank-Up Xyz monster, "Dark Requiem Xyz Dragon", but Edo managed to end the Duel with a draw by negating the attack and inflicted damage to both of them. The impact caused Yūya to be trapped under rubble while Edo was fetched by his subordinates.

Shun vs. Kaito
Kaito, who was hunting Academia students, was confronted by Shun. Understanding Kaito's bitterness and suffering after losing his family was the same when he lost his younger sister, Shun challenged Kaito to a Duel to remind him the importance of their bonds with their comrades. Shun tried to convey his trust in his new comrades, the Lancers, by continuously using Action Cards to power up his monster and revealed how he felt when Ruri was kidnapped. Unfortunately, this wasn't enough to convince Kaito and led to Shun's defeat. Kaito intended to turn Shun into card, but left after Sayaka begged him not to as she revealed how she witnessed Ruri's abduction and blamed herself for not trying to help Ruri at that time.

ARC Area Project
Asuka explained to Yuzu of Academia's plan to unite the four dimensions called ARC Area Project. It was supposed to be a plan to create utopia, but instead it was actually a complete subjugation of the whole dimensions. Her friend, who was sent to Xyz Dimension, told her how they carded not only Duelists, but also unarmed civilians. Traumatized, her friend convinced her to escape, but they were caught by Academia guards who then turned her friend into card, horrifying Asuka. She was saved by Yūshō who just arrived after being sent by Edo, and after hearing the whole thing from Yūshō, they decided to build You Show Duel School that sheltering former Academia students who disagreed with Academia's teaching. While escorting another run away, eight of You Show students encountered Yūri, who managed to card one of them. While two students escorted the escapee back to the school, the remaining five students stayed to avenge their friend who was carded by Yūri. Even though they have advantage in number, they were no match against Yūri's ace monster, "Starve Venom Fusion Dragon" that defeated all of their monsters at once during Yūri's second turn. Before Yūri can take on Yuzu and Asuka who came to help, he got transported to another location by Yuzu's bracelet due to Yūgo's arrival.

Resistance & Lancers vs. Tyler Sisters
Mamoru Noro, Edo's Vice Commander-in-Chief, secretly asked for reinforcement behind Edo's back. Receiving the report that Lancers has been sighted in Xyz Dimension, Leo ordered two of his Duelists, Gloria Tyler and Grace Tyler, to deal with the Lancers at Heartland. On their way to Academia HQ in Heartland, the sisters encountered Sayaka and Allen when the former went out to look for Kaito. Mistaking them as Lancers, they challenged them to a Tag Duel. The Tyler Sisters, who were revealed to be the ones responsible for annihilating the majority of Heart Duel School's Spade branch's Duelists, easily defeated Allen and Sayaka with the combination of their Amazoness monsters. Gongenzaka and Shingo arrived to help just before they could turn Allen and Sayaka into card, but got defeated as well due to Gongenzaka and Shingo's Deck were complete mismatch in Tag Duel. Yūya and Shun came soon afterwards, taking over the Duel.

Yūya & Shun vs. Tyler Sisters
The sisters already thought up a strategy to counter against Pendulum Summon, increasing their LP every time Yūya and Shun special summoned monsters to the field and negated their battle damage. The situation worsened with Yūto and Shun let their anger got ahead of them, which only provided the sisters with more LP until Yūya asked them to trust him. Yūya able to come up with a plan that will deplete all of the sisters' LP in one turn by powering up their monsters' ATK with their effects and "Smile World", and then activated his magic card "Miracle Rocket Show" that inflicted direct damage to them equal to the amount of battle damage that was negated, defeating the sisters.

Duel Against the Obelisk Force
On their way returning to the hideout, Yūya and the others were ambushed by the Obelisk Force who were sent by the Professor in case the Tyler Sisters were defeated. Since Gongenzaka and the others were still injured, Yūya and Shun take on the Obelisk Force by themselves. Yūya and Shun worked well together until the Obelisk Force summoned "Antique Gear Chaos Giant", the monster that destroyed the majority of Heartland. Seeing the monster triggered Sayaka's trauma that caused her to run away. The monster's attack destroyed the surrounding area, causing a rubble to fall above Sayaka. Shun quickly rushed to protect her, severely injuring him. Sayaka was saved, but Shun's injury was too much for him and he collapsed, which terminated him from the Duel, leavin Yūya to fight alone. With the Obelisk Force all ganging up on him, Yūya was quickly cornered, but he was fortunately saved by Kaito who used an Action Card to change his monster to Defense Mode and then swiftly defeated the Obelisk Force alone. The Tyler Sisters were about to challenge Yūya and the others for a rematch before they can retreat, but Edo then arrived with his squad and surrounded the Lancers and Resistance.

Final Duel Against Edo
Edo forced Yūya into a Duel, while Kaito dealt with the Academia squad. Still believing in his philosophy, Yūya tried to connect with Edo by summoning his Fusion monster, "Brave-Eyes Pendulum Dragon", but was quickly destroyed by Edo's ace monster's "Destiny HERO - Dystopiaguy". Recognizing a thorn "Smile World" that Edo was holding belonged to his father, Yūya demanded Edo to tell him how he got it. Edo explained his first meeting with Yūshō; after hearing how Yūshō was spreading words that Duel is supposed to bring smile, he challenged Yūshō to a Duel to prove that the Professor's teaching is correct while Yūshō's philosophy of bringing smile with Duel is wrong. However, Edo lost against Yūshō and he still refused to acknowledge his philosophy. Edo then accidentally sent him to another dimension while he was in distress. Since then, Edo has been looking for Yūshō, and then encounter his son, Yūya, and determined that he must not lose against Yūya who also shared the same philosophy as his father.

Academia's Defection
Realizing that Edo was in the state of self-denial, and was actually thorn between Leo's teaching and Yūshō's philosophy, Yūya determined to open Edo's heart with his Entertainment Dueling. Using "Smile World" and "Brave-Eyes" while running around the Field to get Action Cards, Yūya showed Edo how fun Dueling can be and slowly opened Edo's heart. This reminded the Commander-in-Chief of the joy he felt when he Dueled Yūshō that he refused to admit. With the two cards, Yūya defeated Edo in his Entertainment Duel style and made him see through the error of the Professor's teaching. Right after the Duel ended, the two were then surrounded by another squad of Academia prepared by Noro who was expecting Edo to lose. Edo and Tyler Sisters, who were amazed and acknowledged Yūya's Entertainment Dueling, decided to join his side, defecting from Academia. Noro attempted to take charge as the new Commander-in-Chief, but was interrupted by Kaito and Allen who arrived after bringing reinforcements. Edo then persuaded the entire Academia squad to abandon ARC Area Project and cut their ties with Academia. Noro was also forced to surrender after being threatened by Kaito.

Aftermath
Putting down their weapons, the former Academia squad started to help rebuilding Xyz Dimension, providing the refugees with foods, drinks, and everything needed. Allen was still skeptical with the former Academia's defection, especially Edo, but Yūya told them to believe in them, and Yūto told them what Yūshō believed: forgiveness is the only way to end conflict for good, a sentiment shared by Kaito. Edo then revealed that there is a way to return the people who were carded back to normal. All the carded people were sent to Academia in Fusion Dimension through the device in Heartland's Academia HQ. Yūya, Shingo, Gongenzaka, and Kaito decided to go to Fusion Dimension using the device while Edo and the others stayed to rebuild the Xyz Dimension and tending the injured Shun.

Ambush at You Show Duel School
With Yūri's attack, Asuka proposed to Yūshō that they should attack Academia now while they have the chance. Yūshō agreed with her suggestion and was about to prepare, but Dennis and a squad of Academia Duelists arrived, finding their location based on several witnesses' testimony. Dennis, who was revealed to be Yūshō's former student, challenged Yūshō to a Duel, which Yūshō accepted. Yūshō used his Trap card to distract Dennis and bought some times for him and his students to escape from them, going to the harbor. On their way to the harbor, Yuzu and Yūgo were surrounded. Before they could Duel, Yūgo got transported by Yuzu's bracelet due to Yūya and the others' arrival. Dennis tasked Isao, who bear a grudge against Yūya over his defeat during Maiami Championship, to deal with Yūya, while Dennis chase after Yūshō with Kaito following him in tow.

Yūya vs. Isao
Gongenzaka and Shingo protected Yuzu, allowing Yūya to concentrate on Dueling Isao. Learning from his previous defeat, Isao utilized his newfound power to Fusion Summon Level 12 Fusion Monster "Shura the Supremacy Star" that damaged himself but also strengthened his monster based on the Level of its own and Yūya's monster, which doesn't apply to "Dark Rebellion Xyz Dragon" since it's an Xyz Monster that doesn't have any Level. He also prevented Yūya from getting any Action Card by attacking him directly like before, but Yūya this time able to dodge most of Isao's attacks thanks to the roller skates he received from Allen. Yūya also countered "Shura's" effect by giving Level to "Dark Rebellion Xyz Dragon" and eventually cornered Isao. Refusing to admit defeat the second time, he attempted to force the Duel into a tie, but Yūya managed to save both himself and Isao using his trap card, "Acrobat Tower" and defeated Isao after winning the gamble from the trap card. Isao lamented over his second lost, but as he watched how the audience were impressed and clapping for their Duel, Isao acknowledged that Yūya's Entertainment Dueling is not as bad as he believed it to be, much to Yūya's happiness.

Kaito vs. Dennis
Dennis caught up to Yūshō and Asuka just as the ship left the harbor and demanded for their Duel to be continued. Kaito interrupted and took the challenge in Yūshō's stead, and the two begin the Duel. Dennis has advantage in the Duel with the combination of his Fusion and Xyz Entermage monsters since he already knew Kaito's deck based on the data gathered by Academia who placed a bounty on him for defeating many of their Duelists. However, Kaito able to turn the tide when he summoned "Little Fairy", Sayaka's card that she has entrusted to him and was not on his data. Using the fairy's effect, Kaito performed Rank-Up Xyz Summon, summoning "Neo Galaxy-Eyes Cipher Dragon" and won the Duel. Yūshō invited Dennis to join him so they can change Academia together with their Entertainment Dueling. Dennis, however, declined his offer, feeling that he has not right to return as their comrades after betraying Yūya, Shun, and the Lancers. As he slowly walked backwards to the edge of the ship, Dennis revealed where Ruri and Rin were being held captive. Now he couldn't return to Academia as he has betrayed the Professor by revealing his secret, Dennis sealed himself into a card as a form of redemption, much to Yūshō's dismay who then kept his card.

Duel Against Solo
Yūya and the others arrived at the harbor, but the ship already set sail. They tried to find other ship, but couldn't find one. Unexpectedly, they met Serena who led them to a pirate ship that she assured can be trusted, introducing them to its captain, Captain Solo. On their way to Academia, an Academia helicopter came and Serena suddenly restrained Yuzu, handing her over to the Academia Duelists and left with them, leaving Yūya, Shingo, and Gongenzaka against Solo and his crew, Solo's crew tied Shingo and Gongenzaka, while Yūya dueling against Solo. Solo's monster, "Captain Lock's" effect prevented Yūya from summoning any monster, forcing Yūya to rely on Action Card. To prevent Yūya from getting one, Solo has his crew moved the ship around whenever he was about to get it, and when Yūya finally got one, it was self-inflict card. They were saved by the remaining Lancers with Sora and Crow joining as new members. With Sora's Fusion Monster, "Death-Toy Piton Kraken" and Yūya's Trap Card, they defeated Solo. Before leaving, Tsukikage has sabotaged Solo's ship to prevent him and his crew from following them, causing the ship to go in circles. Yūya believed that Serena didn't capture Yuzu out of her own will, and Sora confirmed this, revealing there is someone within the Professor's inner circle who has ability to control people's heart. Yūya and the others began to discuss the reason why Leo captured Yuzu and the girls who bears the same face as her. Reiji revealed that he once had went to Academia three years ago where he met his father who immediately sent him back. And afterwards, Reiji found one of many files of Leo's research containing a plan known as "Revival Zero" with young Serena and Yūri's photos inside it. He deduced that not only the girls, Yūya and his counterparts are most likely also involved in Academia's plan. This made them even more determined to stop Academia and the Professor's ambition.

Saving Rin and Ruri
Following his teleportation, Yūgo found himself in the middle of Academia class. He eventually came across Kaito, Yūshō, and Asuka upon their arrival. While Yūshō and Asuka go to Leo's place, Yūgo and Kaito both head to the towers where Rin and Ruri were being held, Rin in Eastern Tower and Ruri in Western Tower. They encountered the guardians, Apollo and Diana, respectively. Using similar tactics, Apollo and Diana used their monsters' special abilities to weaken Kaito and Yūgo's monsters that put them at a disadvantage. However, Kaito and Yūgo managed to summon "Crystal Wing Synchro Dragon" and "Neo Galaxy-Eyes Cipher Dragon" to win their respective duels. Just when they were happy with their reunion, Rin suddenly pushed Yūgo away. At the same time, Ruri also did the same to Kaito, but he was fortunately saved from the fall by Shun who came with Edo after insisting that he will save his sister himself. Hearing what Ruri had done, Edo believed that Ruri was being controlled, having heard a rumor that someone by the Professor's side has the ability to control people's heart. Concluding that the same also happened to Rin in Eastern Tower, Kaito told Edo to go warn Yūgo. Confirming that Rin and Ruri were being controlled, Yūgo and Shun dueled them respectively to free them. During their Duel, both Ruri and Rin summoned monster that shouldn't have been in their Deck, "Parasite Fusioners", and they even performed Fusion Summon with it. It turned out that the controller has implanted his Parasite monsters inside Ruri, Rin, and Serena's brain to control them that also allowed it to gain access to their memories that gave them advantage in Duel. Ruri was able to resist the Parasite's control at the last moment, allowing Shun to defeat her. Rin, however, was still controlled despite Yūgo's efforts and she defeated him. Yūgo informed Edo who arrived too late about "Parasite Fusioner", and Edo concluded that the one who controlled both Rin and Ruri was Doctor.

Survival Duel
The Lancers took a shortcut to the Professor's lab. They were blocked by Academia students led by their instructor, Sanders. Reiji, Reira, and Sora went ahead to where the Professor is while the remaining Lancers fighting against the Academia students. Yūya and the others fell into their trap and was forced into a Survival Duel against five of Sanders' students. However, as the Duel started, they found Academia students getting carded one by one even though none of them has started a Duel against them, prompting Shingo to look for their opponents, causing the Lancers to split up further. Tsukikage, who rushed ahead to find out about the enemy, was ambushed by the mysterious Duelist and left a message moments before he got carded. From the message, Yūya and Gongenzaka deduced there was one more person beside them and the five Academia students. Shingo and Crow were ready to Duel against two Academia students, Emma and Jacob, but then the mysterious Duelist intruded the Duel, carding Emma and Jacob in a flash. The mysterious Duelist couldn't be seen since he was hiding in the jungle, so Crow decided to take a risk to expose the mysterious Duelist. He broke Shingo's Duel Disk to forcefully terminated him from the Duel before using his Trap Card to destroy the part of the jungle where their opponent was hiding. Crow's plan was successful in exposing their attacker, Battle Beast, but came at the cost of his entire LP. Battle Beast turned Crow into card as Yūya and the others watched helplessly. Enraged, Yūya and Gongenzaka challenged Battle Beast to a Duel. They were cornered by Battle Beast's "Gladial Beast" monsters, and Gongenzaka was defeated in his attempt to protect Yūya. Before he could be turned into a card, Jack arrived and Dueled in his place with Yūya. Jack's arrival prompted Sanders to join the Duel as well, which unnerved Battle Beast. Sanders' continuous demand for Battle Beast to follow his order and threat that he will be turned into a card pushed Battle Beast to attack Sanders. From Battle Beast's behaviour, Yūya realized that Battle Beast actually didn't want to hurt anyone, becoming the way he is due to the isolation and severe training he suffered at Sanders' hands, and he was simply trying to protect himself, but didn't know how other than turning his opponents into a card. Realizing how deep Academia's teaching has been embed into him and the other Academia students, Yūya performed his Entertainment Dueling to show how fun Dueling can be without hurting anyone. His Entertainment Dueling succeeded in winning over Battle Beast and the students to their side. Yūya was escorted by a student to where Yuzu was while Jack and Shingo stayed behind until Gongenzaka recovered.

Yūri vs. Asuka
Reiji, Reira, and Sora met Yūshō and Asuka on their way to the Professor's chamber, but Yūri then arrived to stop them. Asuka and Sora stayed behind to hold him off, urging Reiji, Yūshō, and Reira to go to the Professor's chamber without them. Already doing a background check on Asuka, Yūri Dueled Asuka with the Honor Student Deck that she used while she was still a student despite not knowing about the Deck the first hand. Asuka seemingly got the advantage since she knew full well about the Deck and already has a card to effectively seal any Fusion Summon using "Fusion Destruction", cornering Yūri, and Asuka attempted to convince Yūri to change side. Yūri then revealed his lonely past and how he Dueled and turned many people into cards for the Professor's sake who was the first person to acknowledge him. However, he then stated that he now doesn't care about the Professor's order anymore because he came to enjoy carding people only for his own amusement and decided to continue doing so until he is the only person left in the world which will prove that he is the strongest. Yūri revealed that he had added his own card into the Deck, "Super Fusion", that allowed him to perform Fusion Summon using his opponent's monster, defeating Asuka. After carding her, Yūri prepared to Duel Sora, disabling the fence that was separating them that he purposely left as it was so Sora will be the spectator of his Duel. Yūri and Sora Dueled, which resulted with Yūri's victory. Before Yūri could turn Sora into a card, he was interrupted by Edo and Yūgo's arrival with the latter challenged him to a Duel while the former went to look for the Doctor.

Duel Against Ruri & Serena
While going down from the tower, Shun collapsed from his previous wound, prompting Ruri to leave him and look for Kaito for help. Directed by the Parasite inside her brain, she went to the Doctor's lab where she met Yūya who was directed there by a Academia student who turned out to have been controlled by the Doctor as well. Hearing what happened to Shun, the two were about to go to where he is, but the Doctor then has Ruri under his control again, forcing Yūya to Duel her. Yūto's feelings for Ruri allowed Yūya to use Yūto's card. Shun then arrived and informed them that the only way to save Ruri is by defeating the one controlling her since Ruri was still under his control even after Shun destroyed the "Parasite Fusioner" in their Duel. Shun was about to go look for the Doctor, but was knocked out by Serena who then join the Duel. Hearing Yuzu also has a parasite inside her brain, Yūya went into rage until he was calmed down by Yūto who then switched bodies with him, taking over the Duel for a few turns before Yūya took over once more. A Parasite entered Yūya's head and attempted to take control of him, but it was killed by an unknown darkness inside Yūya. Serena and Ruri cornered him further with the combo of their "Parasite Queen" and "Parasite Generator" that revived all "Parasite Fusioners" in their Graveyard, which increased the Queen's ATK for each one of them, and negated any destruction by effect directed towards the "parasite Fusioners". The Doctor then appeared from the monitor and showed how he has Yuzu under his complete control, enraging Yūya. This caused Yūya and Yūto to be controlled by the darkness, summoning "Odd-Eyes Raging Dragon" that destroyed all of the parasite monsters in one fell swoop, followed by direct attack towards Serena and Ruri, defeating them.

The Demon Duelist Zarc
Yūya followed Serena and Ruri who ran away after being defeated. He was lured into the Doctor's lab where he got imprisoned. From the monitor in the lab, he saw his father, Reiji, and Reira finally confronting Leo, and learned that his father was acquainted with the Professor. Leo then revealed the reason behind his actions by first explaining that the technology of adding mass into Solid Vision he was credited with creating was actually a technology that was existed in United World, a realm where all summoning methods existed. He was a researcher in that world and used this technology to enhance the game of Duel Monsters and bring life to the monsters. Everything changed when a Duelist named Zarc began to use the technology to Duel violently to answer his audience's expectations for more flashy and strong Duel. Even though he has rise to the top of Dueling world, Zarc's thirst for more battle and power has not yet be satisfied, leading him to suddenly used his dragons to wreak havoc as he declared that he will continue to fight and win until he destroy the whole world. During the attack, Leo also noticed that the dragons were no longer just attacking under Zarc's control. From this, he learned that Duel Monsters has souls, and the dragons who were furious for being forced to fight to satisfy people's desire now unleashed their rage towards them. Since their bodies were made from Real Solid Vision, modern weapons were ineffective against them. Even after destroying the whole city, neither the dragons nor Zarc were satisfied, so Zarc then fused himself with his four dragons to obtain more power, becoming the ultimate monster known as Supreme King Dragon Zarc and sent the world to the verge of destruction. As Leo told the story, Yūya and Yūto began to experience an abnormality within them as their "Odd-Eyes" and "Dark Rebellion" shining at the same time as Yūgo and Yūri summoning their respective dragons. Using his power, Yūya broke free from his cell and headed to the Professor's chamber, blowing away Kaito and Edo who arrived after hearing what happened from Shun.

Revival Zero
When Yūya arrived in the chamber, Leo told Yūshō that Yūya is his son but at the same time he is not, confusing them. He then showed them Yuzu and the other girls placed inside capsules behind him. The Doctor asked for his permission to use the girls to defeat Yūya, but the Doctor's dangerous thinking led Leo to card him, freeing the girls from the brainwash. Leo then continued his story, explaining that since Zarc was born from people's negative desire, Leo created four cards by using the power of nature. When he finished the card, however, his daughter, Ray, stole the cards and sacrificed herself to stop Zarc in his place. The clash between the two caused the original dimension to be split into the current four dimension they knew now and everyone including Leo himself lost their memories of the original world. Leo started developing the Solid Vision with mass technology from scratch and began to regain his memories of the original world and Ray. Believing that Ray was still alive, he crossed dimensions to look for her, and finally found her trace in Academia: Serena. When he checked Serena's memory though, there were no traces of Ray's memory, so Leo concluded that Ray must have also split into four different lives following her clash against Zarc, revealing Yuzu, Serena, Rin, and Ruri are Ray's reincarnation. Leo explained that his goal was to revive Ray by using the life energies of the people who were carded and gathered in the machine behind his throne that will absorb the four dimensions and become the fifth dimension named ARC-V where the girls will revived as Ray. Remembering the file named Revival Zero containing Serena and Yūri's pictures, Reiji correctly deduced that if Yuzu and the other girls were Ray's reincarnations, then that means Yūya, Yūto, Yūgo, and Yūri are Zarc's reincarnations who also got split during the clash against Ray, which Leo confirmed, and Yūya and Yūto now know that the darkness inside them was actually Zarc trying to take over them so he can be revived. Leo asked Reiji to defeat Yūya with him before Zarc revives and destroy the world again, but Reiji refused, choosing to trust and side with Yūya who has united the City and stopped Academia in Heartland to stop Leo's ambition, leading to their Duel.

Duel Against Leo
Since Yūya and his counterparts were all present in Academia, Leo decided to immediately begin the process of combining the four dimensions and fuse the girls, urging Yūya and Yūto to finish the Duel quickly and stop the machine. Reiji used his monsters' effect to stop Leo from summoning any Fusion, Synchro, or Xyz monsters. However, Leo revealed that he also has Pendulum Cards, allowing him to Pendulum Summon and summoned his ace Monster, "Spirit Tech Force - Pendulum Governor", which drove Yūya and Reiji into corner. Meanwhile, Yūshō came into realization that he has no memory of Yūya's birth, which also happened to Shūzō, and concluded that Zarc has chosen him to raise Yūya as a Duelist so he can be reborn. Seeing the predicament that the girls were facing enraged Yūya and Yūto, which caused Zarc's consciousness began to resurface within them, who tried their best to hold him off. Unfortunately, Yūya started to behave more and more like Zarc, only barely controlling himself. Zarc's influence worsened when Leo has his subordinates to fasten the integration process that caused the girls' body started to disappearing, enraging Yūya and Yūto further who began to attack Leo violently. This caused Yūya to be possessed by Zarc and was about to deliver the finishing blow with "Odd-Eyes Raging Dragon", but Yūshō used a bugged Trap card "Binding Swords of Impact" to restrain Yūya and terminated the Duel. Convinced that Leo's story was true, Yūshō went to look for Yūri and Yūgo to stop from advancing Zarc's revival.

Yūri vs. Yūgo, Edo, & Kaito
Kaito and Edo, who was looking for Yūya after witnessing his power in the Doctor's lab, met Yūshō. Hearing about Yūya and his counterparts' connection with Zarc, Edo informed Yūshō that Yūri and Yūgo were Dueling at the moment before heading there to stop the two. Edo and Kaito intruded the Duel and decided to first return Yūgo, who was under Zarc's influence, to his senses. Kaito started his turn by taking "Clear Wing Synchro Dragon" and "Starve Venom Fusion Dragon" under his control and decrease Yūgo's LP so Edo will have more chances, but Yūgo able to defend himself with his monster's effect. Edo tried to reach Yūgo by reminding him of his real reason coming to Academia: to save Rin, which made Yūgo hesitated for a moment and convinced Edo and Kaito there was still hope of returning Yūgo to normal. After trading blows with each other, Edo finally succeeded in returning Yūgo to normal, and the three of them now prepared to Duel Yūri. Yūri used "Super Fusion" to take back "Starve Venom" and used it as Fusion material to summon "Greedy Venom Fusion Dragon". He tried to used its effect on "Destiny HERO - Duskutopiaguy", but Yūgo used "Crystal Wing Synchro Dragon's effect" to negate and destroyed it. However, Yūri then activated "Greedy Venom's" other effect to destroy all of their monsters the moment it left the Field and inflict damage equal to their ATKs. Edo used "Duskutopiaguy's" effect to prevent "Crystal Wing's" destruction, saving Yūgo from defeat. Continuing their Duel, Yūgo decided to defeat Yūri by finishing all of his LP in one swift attack by using the combinations of his monster effects and revived his "Clear Wing" to the field while also reducing "Greedy Venom's" ATK and increasing "Clear Wing's" ATK in the process. Unfortunately, Yūri already anticipated this and brought back "Starve Venom" with his Magic card and monster effect, defeating Yūgo. The Duel made Yūri realized his connection Yūgo, Yūya, and Yūto. Wholeheartedly embracing Zarc's desire to become one again, Yūri absorbed Yūgo into him, obtaining Yūgo's "Clear Wing" and gained complete control of Zarc's power. Knowing he is not yet complete, Yūri turned to Yūya as his next target, sensing him nearby.

Reiji vs. Reira
As the ARC-V energy input reached 60%, Yuzu and her counterparts went unconscious and Leo began to transfer them into ARC-V one by one. Fragments of Ray's soul left their body to communicate with Reira who was able to hear her voice due to his traumatic experience as a war victim developed his senses. Hearing Ray's plea to help her revival because she was the only one who can stop Zarc, Reira betrayed Reiji and challenged him to a Duel to stop him from interfering with Ray's revival. Reiji accepted Reira's challenge and was quick to corner him, but to his surprise, Reira still decided to continue the Duel. With Ray's support, Reira summoned a new monster, "CCC Sonic Halberd the Embodiment of Fused Arms", that Reiji never saw before and countered his attack. Reiji survived by using an Action Card to negate battle damage and finally decided to get serious, admitting he was underestimating Reira in the beginning because he was the one who taught him how to Duel. Reiji special summoned "DDD Knowledge King Tomb Conquistador" and used its effect together with his magic card to increase his monster's ATK that overpowered "Sonic Halberd" and defeated Reira. When Reiji was going to rush towards Reira who he has defeated, the wall beside them explode, revealing Yūshō who got blasted away by Yūri.

Yūshō vs. Yūri
Yūri arrived to absorb Yūya, ignoring Yūshō and Reiji who tried to stop him from getting near Yūya until he learned that Yūshō is Yūya's father. Seeing Yūshō's determination to protect Yūya and avenge his students whom Yūri has carded, Yūri consented to Yūshō's challenge. Wanting to end the Duel quickly, Yūri started his turn by simply setting two cards and summoned one monster, confident it was enough to defeat Yūshō. Knowing this, Yūshō deduced that Yūri was planning to defeat him using one of the two set cards. To know which and what kind of card it is, Yūshō baited Yūri into revealing his trap card that changed his "Entermate Sky Magician's" attribute into DARK, which he dispelled using his spell cards as he attacked Yūri. Based on the effect of Yūri's trap card that changed his monster's attribute into DARK, Yūshō easily guessed that Yūri intended to make "Sky Magician" a Fusion material and concluded the other set card was his trump card, "Super Fusion". Using his magic card "Clairvoyance", he forced Yūri to return the card into his deck after he correctly guessed it. Yūshō continued to attack in his Entertainment Duel style, negating Yūri's continuous Trap card and destroying all of Yūri's summoned monsters. Watching his father's Entertainment Duel freed Yūya and Yūto from Zarc's power. Despite the damage he took, Yūri remained optimistic that he would win as he revealed that his trump card is not "Super Fusion", but "Transcendental Fusion" that allowed him to perform both Fusion and Synchro Summons, summoning "Starve Venom" and "Clear Wing". Using the monsters' effects in conjunction with his two continuous spell cards, Yūri form a vicious combo that repeatedly decreased Yūshō's LP and "Sky Magician's" ATK. Seeing Yūri tormenting his father caused Yūya to once again got influenced by Zarc's power, which finally reached its apex once Yūri defeated and carded his father while laughing.

Yūri vs. Yūya
Furious at Yūri for carding his father, he accepted Yūri's challenge to take back his carded father. Zarc's influence became harder to resist than before, and it took all of Yūya and Yūto's power to resist it when Yūri and Yūya summoned "Starve Venom", "Clear Wing", and "Odd-Eyes" respectively. Yūya sealed Yūri's dragons' effect using "Starlight Force" and decreased their levels, preventing Yūri from using the same vicious combo that he used against Yūshō. Yūya and Yūto decided to take a huge risk of increasing Zarc's influence within them to defeat Yūri by summoning "Dark Rebellion", consequently led Yūto's soul to be taken over by Zarc. To Yūya's horror, Yūri already anticipated this move and activated his continuous Trap card, "Dragon Creeping Plant", gaining control over "Dark Rebellion". At the same time, Leo has finished with transferring all the four girls into ARC-V and began to activate it, staring the dimensional integration. With the three dragons on Yūri's side and both Yūgo and Yūto completely fallen into Zarc's control, Yūya was close to give into Yūri's temptation to become one with him, but was able to resist it at the last second after Reiji reminded him of his father's last wish. Yūya tried to survive using Action Cards, but Yūri foiled his attempt by using Action Card that negated his. With the four dimensions started to unify, Leo trapped Yūya, Yūri, and the others inside Isolation Dome until Ray is revived together with the four cards necessary to defeat Zarc. Reiji, Reira, Edo, and Sora attempted to join the Duel to protect Yūya, but Yūri swept them away. Yūya began to lose hope after being forced to send "Smile World" to the Graveyard to survive, but the support he gained from his friends convinced him to continue fighting until the end. Yūya finally able to turn the tide to his favour by using the effects of his two monsters that allowed him to take control of both "Dark Rebellion" and "Clear Wing". Using "Dark Rebellion's" effect, he decreased "Starve Venom's" ATK to 700. Yūri countered it by activating "Ridicule World" that increased Yūya's monsters' ATKs but made them unable to attack on this turn. In respond to this, Yūya changed back "Odd-Eyes'" ATK into its original ATK using "Entermate Flat Rat's" effect and attacked "Starve Venom". With "Odd-Eyes'" Reaction Force, the battle damage was doubled, dealing enough damage to deplete all of Yūri's LP, defeating him.

Revival of the Supreme King Dragon
Defeated, Yūri returned Yūshō's card and resigned to his fate to be absorbed by Yūya, content with the result of the Duel despite being the one who lost. When Yūya approached him, it turned out that the feelings he got from his friends and Reiji's suggestion to focus only to win the Duel overlapped with Zarc's memories of his fans cheering for him to win his Duel in flashy violent way, which inadvertently caused Yūya to completely succumbed to Zarc's control. Fully possessing Yūya's body, Zarc began to absorb Yūri into him and fused "Timegazer Magician" and "Stargazer Magician" into "Astrograph Magician". With its power, Zarc fused himself with the four dragons, reviving him as Supreme King Dragon Zarc.

Zarc's Attack
Zarc's revival was seen throughout the whole dimensions due to the dimensional integration. Bitter towards humans who he deemed responsible for his rebirth, Zarc began his attack on Academia and the city of Fusion Dimension all the while demanding someone to challenge him to a Duel. Hearing Ray's plea for her father to quickly revive her, Reira went back inside Academia to look for Leo with Reiji following him, while Edo and Sora looked for Zarc. Inside ARC-V, Leo couldn't find any traces of Ray's life reaction and assumed that the life energies that were gathered and used were not enough yet to revive her.

Edo & Sora vs. Zarc
Protecting civilians from Zarc's attack, Edo and Sora challenged Zarc to a Duel. Accepting the challenge, Zarc revealed his demonic form that resembles Yūya combined with monster and told them that Yūya no longer existed since he has fulfilled his purpose of reviving the Supreme King Dragon as his reincarnation. Believing that Yūya's soul still existed inside Zarc when the Demon Duelist performed Pendulum Summon, Edo and Sora determined to bring back Yūya's soul through their Dueling. Zarc proved to be formidable opponent for them as his monsters' effects not only negated their battle damage, but also increased his own LP for each of the battle damage he was supposed to receive. Edo and Sora continuously tried to reach Yūya's heart. To break Zarc's combo, Edo sacrificed some of his LP to activate "Destiny HERO - Dystopiaguy's" effect to destroy one of Zarc's "Supreme King Servant Dragon Darkwurms", allowing Sora to destroy it on his turn. Sora tried to reach for Yūya by showing his Pendulum Pendant and reminded him of their first Duel, but Zarc remained unresponsive. Sora and Edo were able to banish all of Zarc's monsters on his Field using the combination of their Trap Cards and thought they'll reach Yūya's heart soon. However, it turned out that Edo and Sora's action has allowed Zarc to special summon "Astrograph Magician" whose effect returned all of his banished monsters and performed Integration Summon by fusing himself with the Four Heavenly Dragons, becoming "Supreme King Dragon Zarc". Using his power, Zarc destroyed "Dystopiaguy" and "Death-Toy Mad Chimera", and inflicted damage to Edo and Sora equal to the total of their destroyed monsters' ATKs, defeating them.

Shun & Kaito vs. Zarc
After seeing Edo and Sora fighting against Zarc, Shun and Kaito arrived and intruded the Duel just before Edo and Sora were defeated. Sora entrusted Yūya's pendant to Shun, begging him and Kaito to save Yūya. Accepting the task, Shun and Kaito challenged Zarc. Shun summoned his ace monster, "Raid Raptors - Rise Falcon", and Zarc followed the suit by summoning "Supreme King Servant Dragon Dark Rebellion" right after Shun did on his turn. Zarc then used "Dark Rebellion's" first effect that prevent either Shun or Kaito from attacking other Xyz Monster other than "Dark Rebellion". Since Zarc is the integration of all the summoning methods, it's also treated as an Xyz Monster and thus, cannot be attacked. Shingo and Gongenzaka then arrived, asking Sora and Edo for explanation of what was happening. Due to the effect, Shun directed his attack on "Dark Rebellion" instead, but Zarc then used its other effect to reduce "Rise Falcon's" ATK to 0 and added it to "Dark Rebellion". Shun avoided battle damage by activating his spell card and despite failing to attack, he already has a back up plan in his mind. Kaito tried to take control of "Dark Rebellion" using "Galaxy-Eyes Cipher Dragon's" Cipher Projection, but Zarc used his power to make all Fusion, Synchro, and Xyz effects ineffective against any of his monsters as long as he is present on the Field. Meanwhile, Reiji and Reira kept going around in circle and saw the people of City and Heartland City walking through them that Reiji deduced to be the impact of dimensional integration. In Heartland, wormholes started to appear and sucked people who were nearby. Sayaka saw Shun and Kaito Duelling from the crack in the sky, which made her not noticing the wormhole behind her. Allen tried to help her run away, but both got sucked into the wormhole and ended up at Shun and Kaito's place, surprising Shun. As Zarc attacked them, Shun and Kaito activated their Traps by paying half of their LPs to perform Rank-Up Xyz Summons, summoning "Neo Galaxy-Eyes Cipher Dragon" and "Raid Raptors - Revolution Falcon" with their ATKs doubled. This didn't worry Zarc in the slightest who used the last effect of "Dark Rebellion", returning "Dark Rebellion" back to Extra Deck and revived its Xyz Materials to reduce their monsters' ATKs to 0. Another wormhole appeared behind Allen and Sayaka, sucking them to another location again. Shun and Kaito tried to survive Zarc's incoming attack using Action Cards, but Zarc used his power to negate and destroy any card added to their hands outside Draw Phase. When Gongenzaka and Jack intruded the Duel, Zarc lost interest in Shun and Kaito and defeated them with his two revived "Darkwurms". Shun gave Gongenzaka with Yūya's pendant, entrusting the task to save Yūya to him and Jack.

Jack & Gongenzaka vs. Zarc
Just like he did during his Duel against Shun and Kaito, Zarc performed Synchro Summon during Jack's turn, summoning "Supreme King Servant Dragon Clear Wing". While Jack made his way towards Zarc, Gongenzaka decided to protect Jack's monster at all cost with his monsters to allow Jack attacking. Gongenzaka tried to reach out for Yūya by explaining to Zarc of his and Yūya's Steadfast and Entertainment Dueling respectively. Surprisingly, Zarc responded to the word entertainment that Gongenzaka mentioned by warning that his entertainment will be violent. Due to the dimensional integration, the City and its residents got transported into Fusion Dimension, including Frank, Amanda, Tanner, and Tokumatsu who were watching the Duel from afar. True to his words, Zarc relentlessly attacked Gongenzaka and Jack, using the effect of "Clear Wing" equipped with spell card, Zarc destroyed the majority of Gongenzaka's monsters and inflicted damage equal to the total of their ATKs to Gongenzaka and Jack, which eventually defeated Gongenzaka who used his last remaining monster to protect Jack in the next two turns. Seeing Zarc responded to the word entertainment, Gongenzaka lend Shingo his Duel Disk and Yūya's pendant, telling him to bring back Yūya as now he was convinced that Yūya still exists. Crow, who got revived due to the integration of the four dimensions, joined the Duel together with Shingo. With the chance given to him, Jack was able to destroy "Clear Wing", but Zarc's monsters' Pendulum effects negated its battle damage and instead increased his own LP further. Praising Jack for being the one who entertained him the most so far, Zarc personally attacked and destroyed "Red Daemon's Dragon Tyrant", defeating Jack. Meanwhile, Reira once again received words from Ray who told him that Leo was planning to divide the dimensions once again by using the four cards that she had used before to defeat Zarc. Not wanting anymore sacrifice, Reira convinced Reiji to go stop Leo from sacrificing himself while Reira (who originally intend to go with Reiji) proceeded to go to where Ray is.

Shingo & Crow vs. Zarc
As Crow summoned his ace monster, Zarc once again summoned back "Clear Wing" and used its effect to destroy Crow's "Raikiri", but Crow then activated a Quick Play Spell to special summon it back from Graveyard, though it's once again destroyed by "Clear Wing's" second effect. Crow special summoned "Chidori" in its place and finally able to destroy "Clear Wing" and inflicted 1000 damage to "Zarc" by using his Spell Card's effect. As Crow continuously attacked Zarc, he came to notice from Zarc's defensive play that the Supreme King Dragon feared losing. Crow pointed out this fact to Zarc and tried to use this fact to remind of what he has learned from Yūya. His attempt earned an offended reaction from Zarc who persisted that he will never lose, which proved his fear of losing. Shingo then started his turn by performing Pendulum Summon. And again like before, following Shingo's Pendulum Summon, Zarc special summoned a Pendulum Monster, "Supreme King Servant Dragon Odd-Eyes". Shingo provoked Zarc by pointing out the fact that he is afraid of losing after the latter destroyed a Magic Card added to his hand, which get on Zarc's nerve, and this was furthered when Shingo set the destroyed card on his Field using his other Spell Card that rendered Zarc's effect ineffective. Shingo then continued by using the combination of his Magic cards and monster effect to negate "Zarc's" Trap Card and destroy both the Supreme King Dragon and "Odd-Eyes" at once, shocking everyone at Shingo's seemingly victor. Unfortunately, Zarc survived the first attempt using "Odd-Eyes'" once per turn effect to negate destruction of Pendulum Monster. Shingo once again repeated the same attack using the effect of his continuous Magic Card to bring back the previous Magic Card since Zarc won't be able to use "Odd-Eyes'" effect again, but Zarc foiled his second attempt by using all the monsters he has destroyed as a shield to protect himself, which also revealed that every time monsters being sent to Graveyard, the stronger Zarc's defense will become.

Leo & Reiji vs. Zarc
The dimensional integration almost reached its completion, leading Maiami City to appear as well, and the Resistance Duelists who have been sealed into cards returned to normal following the integration. Realizing the error of his actions, Leo joined the Duel, stating Shingo, Crow, and the other Lancers efforts weren't useless as he determined to sacrifice himself like he had intended to years prior using the four En Cards that Ray once used to defeat Zarc. Reiji also joined the Duel, feeling that not only Leo, the whole society including himself were also responsible for Zarc's rebirth due to their unawareness of the evil deep in their own hearts. Zarc proceeded to defeat Crow and Shingo before changing his target to Leo. Before Leo could use the four En Cards, he destroyed the cards with his Trap Card and inflicted damage to Leo that instantly defeated him. In the core of ARC-V, Reira finally met Ray's spirit and offered himself to become her vessel so she can fight. Reiji started his turn by immediately performing Fusion, Xyz, and Synchro summons, and successfully delivered considerable damage to Zarc with the combinations of their monster effects as he reminded Yūya of his Pendulum Summoning and his role as its pioneer. However, Zarc then revealed that Pendulum Summon was actually created by him, explaining that Pendulum Summon was born from his desire for revenge at the same moment when he was split. Zarc then proceeded to summon all of his four "Supreme King Servant Dragons", which now included "Supreme King Servant Dragon Starve Venom". Using each of their effects to support his attacks, Zarc began his counterattack against Reiji who barely survived his attacks using his monsters' effects. Unfortunately, Zarc succeeded in defeating Reiji after using the combination of "Odd-Eyes" and "Starve Venom's" effects to significantly decreased his LP and then attacked him using "Supreme King Dragon Zarc". Although defeated, Reiji and Leo were fortunately saved by the revived Tsukikage before "Zarc's" attack could crush the both of them.

Ray & Reira vs. Zarc
Reira arrived and intruded the Duel just as Reiji got defeated. However, Ray then revealed herself to have possessed Reira's body and began to activate the four En Cards after fulfilling the conditions to activate them. Using the Magic Cards, Ray and Reira turned all of Zarc's monsters into Normal Monsters that destroyed his status as a Fusion, Synchro, and Xyz monster, turning Zarc into a simple Pendulum Monster and then destroyed it along with the Supreme King Servant Dragons. Zarc still refused to give in, persisting in his quest for vengeance and giving terror to the world for forcing him to fight, but Ray then retorted that Pendulum Summon is not created solely from his hatred, but also from the purifying power of the En Cards that turned all energies into pure existence, and she knew that Yūya's soul is still exists inside him as Yūya is the embodiment of Zarc's inner goodness. Yuzu then appeared from Ray and reminded Yūya of his true wish of bringing happiness to people and how far he went to save her. Yūya's soul slowly reacted to Yuzu and his friends' call that finally awakened his soul inside Zarc and he began to fight against Zarc's control. Taking control of his body and with the help of Yūri, Yūgo, and Yūto, Yūya drew and activated "Smile Universe" to summon back "Supreme King Dragon Zarc" and "Odd-Eyes". Zarc tried to take control again, but Yūya was able to hold him back long enough to make both of their monsters into Normal Monsters and increased Reira and Ray's LP with the total of the dragons' ATKs before allowing Reira and Ray to deliver the finishing blow. Using the "En Flowers'" final effect, Ray and Reira negated all monster effects and destroyed all monsters on the Field and then inflicted 600 damage for each card placed in the Graveyard, destroying both "Supreme King Dragon Zarc" and "Odd-Eyes" that defeated Zarc for good. The Four Heavenly Dragons started to separate again from Zarc, but to prevent Zarc from reincarnating in the four dimensions that may possibly repeat the same tragedy all over again in the future, this time, Ray and Reira instead sealed Zarc's soul into Reira's own body.

Registration
ARC-V once again split into four dimensions. Unlike before, however, Standard Dimension has been reborn as Pendulum Dimension where everyone can use Pendulum Summoning. In the process, everyone lost their memories of the whole events and Yuzu and her counterparts ceased to exist in the new world. Yūya and his friends lived their lives normally until he got an invitation from LDS to participate in Maiami Junior Youth Championship together with Gongenzaka and Shingo. Reiji explained that they will participate in a Battle Royale where they will Duel each other. With everyone watching, Yūya and the others were brought to the Volcano area of Action Field, "Wonder Quartet", which brought a nostalgic feeling to everyone.

Battle Royale
There, they were confronted by Tsukikage and started the Duel. In the monitor room, Reiji was watching the Duel with Himika, Nakajima, and Yūshō. Both Reiji and Yūshō who have regained their memories of the whole events have planned the championship as reenactment of the Maiami Championship in the previous world to remind everyone, particularly Yūya, of their forgotten memories in hope of saving Reira who has been reborn as a baby after sealing Zarc into his own body. Following Reiji's order, Tsukikage relentlessly attacked Yūya as he slowly regained his memories, cornering him, but Yūya was barely able to reduce the attack. The Duel turned into a tag Duel with Shingo teaming up with Tsukikage against Gongenzaka who decided to teaming up with Yūya, who occasionally spaced out during the Duel as he slowly regained his memories of his journey crossing dimensions, but forget the reason why. Shūzō, who just regained his memories about Yuzu after seeing her empty room, announced to everyone that Yuzu is not with them, resulting everyone to regain their memories of Yuzu. Seeing Yūya not concentrating on the Duel due to being reminded of Yuzu, Gongenzaka took over the Duel to protect Yūya and then defeated both Shingo and Tsukikage. Recalling that he crossed dimensions to save Yuzu, Yūya also started to remember his Duel in Academia, and to his horror, including that he used to be Zarc and the horrible things he had done as the Supreme King Dragon. Reiji revealed to everyone who have regained their memories the infant Reira had become, explaining that after defeating Zarc using the En Cards, Reira drove out Ray's soul from his body and then sealed Zarc's evil soul into his own body after expelling him from Yūya's body. The En Cards' purifying power reverted Reira into an infant and Zarc's soul inside Reira caused the boy to be in a catatonic state. Fearing that Zarc may revive once more if it's left as it be, Reiji planned the reenactment of the championship with Yūshō to remind Yūya and polish his Entertainment Dueling so he can make Reira smile that will also pacify Zarc's soul. Learning that Yuzu may also still alive and well, Yūya was left confused as what he must do so he can save both Reira and Yuzu. Gongenzaka encouraged the confused Yūya by casting aside his Steadfast Dueling to attack with Action Cards. Since Gongenzaka has regained his memories, he was able to perform Synchro Summon. Understanding what Gongenzaka was trying to do, Yūya resolved to answer Gongenzaka's expectation by going all out. Both Yūya and Gongenzaka were racing throughout the whole Field while trying to best each other in repeatedly inflicting damage and getting Action Cards. When both of their LPs reached its peak, Yūya and Gongenzaka both tried to reach an Action Card that will determine the outcome of their Duel, which Yūya succeeded in getting and used it to defeat Gongenzaka. Although Yūya won the championship, Reiji told Yūya that he couldn't approve him into Youth Class until he defeated the remaining Lancers. Reiji took Yūya to a dimension corridor connected to Xyz Dimension. Reiji revealed that even though the dimensions has been split again, there were still remnants of ARC-V and Yuzu and other girls were most likely still inside it. Yūya then set off to Xyz Dimension, expecting he will be dueling Shun, but instead he was welcomed by Dennis who informed him that Shun has left for Fusion Dimension to look for Ruri. Receiving challenge from Dennis who revealed that he was Yūshō's student, Yūya accepted.

Yūya vs. Dennis
The Duel between Yūya and Dennis earned attentions from two children who once were saved by Yūya during his first arrival in Heartland. Their mother told them not to watch the Duel until she learned that Yūya was the one who was Duelling, remembering him as the one who saved them before. The children's father was skeptical and against them watching the Duel, but Dennis threatened that he will turn them into card again if they leave by revealing his "Fusion" card. Edo explained to Yūya that even though Academia were trying o atone their sins by rebuilding Xyz Dimension, the severe trauma from their invasion has caused Heartland citizens to condemn Duelling and refused to forgive Academia. Realizing that Dennis was trying to restore the citizens' happiness, Yūya began his Entertainment Duelling, which later also followed by Dennis who dropped his bad guy act. Dennis cornered Yūya with his new Rank-Up Magic monster, "Entermage Trapeze High Magician" whose effect prevented it from being destroyed by battle and continuously foiled Yūya's attempt to get Action Cards. Their Duel soon started to attract more Heartland citizens to watch Duel with Dennis' magic tricks able to amazed the children. Dennis then flew to the top of Heartland Tower and momentarily returned it into its original state while challenging Yūya to catch up to him. At the same time, in Pendulum Dimension, Reiji was watching the Duel with his mother, Yūshō, Reira, and Nakajima. In response to Dennis' challenge, Yūya activated two Continuous Magic Cards: "Hope Stairs" and "Challenge Stairs" that created a way for Yūya all the way to the top of the tower. Reiji deduced that Yūya will summon "Dark Rebellion Xyz Dragon", but Yūya instead used "Odd-Eyes" to attack. Combining his two Magic Cards' effects, Yūya attacked five times and increased "Odd-Eyes" ATK until he defeated Dennis. The Duel successfully restore the citizens' love for Duelling and eased their hatred for Academia's wrong doing. Yūya left Dennis to teach the children Entertainment Duelling while he departed to Fusion Dimension to confront Shun.

Yūya vs. Shun
Arriving in Academia, Yūya was quickly dragged by Sora to where Shun was. Shun demanded for Leo to return Ruri with Asuka trying to calm him down to no avail. Yūya and Sora tried to explain the whole situation regarding Ray and Ruri's connection with her as well as the other girls, but Shun refused to believe so and insisted to meet Leo. Thinking it was the best for Shun to know the truth directly from the Professor himself, they reluctantly allowed Shun to meet Leo, who was trying to revive Ray whose body was still inside the ARC-V Reactor. However, Leo revealed that he wasn't even sure if the one inside the reactor is Ray because Zarc who was defeated now reborn as Yūya alone while Yūto, Yūgo, and Yūri didn't, leading to conclusion that the girls, Yūto and the others has ceased to be. Saddened from losing both his younger sister and best friend yet still refusing to accept the fact, Shun conceded to Yūya's challenge to a Duel, promising he will give up on bringing back Ruri if Yūya wins, while Yūya must never show himself again in front of him if Shun wins, a condition that Yūya accepted without protest. Right from the start of the Duel, both Shun and Yūya went offensive, trading fierce blows towards one another that forced both of them to continuously using Action Cards to either survive each other's attack or negating the other's Action Cards, resulting their LPs to decrease significantly in short times. In retaliation to each others' attack, both Yūya and Shun summoned their new monsters, "Raid Raptors - Final Fortress Falcon" and "Odd-Eyes Lancer Dragon", respectively. "Final Fortress Falcon's" effect forced Yūya to be on defensive by sending back his monsters on his Field to negate "Lancer Dragon's" destruction and battle damage until there's no monster left other than his dragon while Shun could still attack one more time. Yūya activated "Cross Damage" to inflict the damage to both himself and Shun, causing Sora and Asuka who were watching to think the Duel ended up with a Draw until they saw Yūya still standing with his dragon while Shun lay defeated. Yūya revealed that right after he activated his Trap Card, he sent all of his "Odd-Eyes" monsters in his hands to the Graveyard to activate "Lancer Dragon's" effect that halve the damage he took, thus, saving himself from defeat. Even though Shun accepted his defeat, he decided not to fulfil their end of bargain because he has found a new hope: when Yūya activated his Trap Card, he briefly sensed Yūto's presence within Yūya. This convinced Shun that Yūto was still living inside of Yūya, which also means that Ruri must be still alive as well whether she was inside Ray or Yuzu and he won't give up on that hope. With this newfound hope, Yūya became assured and determined to carry out Shun's wish, but he was then cut off by Jack who stated that Yūya couldn't save anyone with the way he is now.

Rematch Against Jack
In response to Jack's claim about Yūya being a coward, Shun remarked that Yūya didn't summon "Dark Rebellion" in their Duel when had the chance even though he has two level 4 monsters, and Yūya admitted that he was unwilling to do so out of fear that Zarc's soul within Reira will awaken, so he decided to find a way to make Reira smile without summoning the dragons. Jack then challenged Yūya to a Duel, demanding him to use the four dragons in the Duel. Already anticipating this, Reiji materialized Riding Courses across dimensions called Dimension Highway that are connected by the remains of ARC-V. Crow brought Yūya's D-Wheel and suits that he used in the Friendship Cup for him to wear. Aware of the fact that he failed to make Reira smile in his previous two Duels, Yūya accepted the challenge. Yūya could sense that the other three dragons wanted to come out, but he insistently against summoning them, thinking that they wanted to be summoned so they can awaken Zarc like before, and afraid that not only Reira will become a demon but something bad might happen to Ray, Yuzu, and the other girls as well if the dragons are summoned. For this reason, Yūya ignored his chances to summon "Dark Rebellion", and instead attacking Jack only by using the combination of "Entermate Drago Remora" to increase "Odd-Eyes's" ATK and decreased Jack's "Red Daemon's Dragon Scarlight's" ATK with "Entermate Odd-Eyes Minotaur's" effect. This disappointed Jack who summoned "Red Daemon's Dragon Tyrant" that quickly cornered Yūya. As Yūya was facing the incoming attack, Yūto, Yūri, and Yūgo made their presence known to Yūya from within himself and voiced their disagreement of losing against Jack now, which they were sure that their dragons were also feeling the same way. They questioned Yūya's ignorance to their dragons' feelings and urged him to listen to their dragons' voices, something that they should be able to do together. This reminded Yūya that they were originally one person, so even though the evil has been purged from their hearts, it doesn't change the fact that he himself was still Zarc who has the ability to communicate with Duel Monsters. Yūya negated Jack's damage that could have finished him by using "Entermate Odd-Eyes Dissolver's" effect at the last second and summoned it to his Field. Finally finding his resolve with his counterparts' support and accepting himself as part of Zarc, Yūya finally summoned all the four dragons at once. Yūya could feel that the dragons were actually afraid that if Ray is revived they will be powerless, and that's why they wanted to stop Ray's revival. Assuring the dragons not to be afraid because they were already strong enough even without becoming the Supreme King Dragon, Yūya determined to use their power to protect people's smile instead of bringing destruction. Yūya began his counterattack by first using "Starve Venom's" effects to reduce "Red Daemon's Dragons's" ATK and then declared battle phase using "Starve Venom", but Jack survived by negating the damage using the Action Card "Evasion" that Yūya had negated prior. Already anticipating the negation, Yūya used "Dark Rebellion's" effect to once again reduce half of "Tyrant's" effect and then attack it with "Dark Rebellion" and "Clear Wing", which Jack foiled by using Action Cards. Still having "Odd-Eyes" on his side, Yūya used his ace to attack that Jack once again tried to prevent by using Action Card that increased "Scarlight's" ATK higher than "Odd-Eyes". Yūya tried to grab an Action Card as well and nearly failed to get one but was helped by "Clear Wing" to reach it and used it to defeat Jack.

The Last Duel
Despite winning the Duel, Reiji showed that Reira still hasn't smile, which means that Zarc's soul was still inside her. This left Yūya confused of what he could do further to make the baby smile as he himself didn't know what he was still lacking to do so. With Yūya has defeated his opponents that Reiji has set up for him, Reiji allowed Yūya to take the final test to advance to Youth Class. Not wanting to wait any longer, Yūya requested for Reiji to let him take the test immediately, a request that Reiji has expected and revealed that the opponent for Yūya's final test is Reiji himself. Using Action Field "Entertainment Colosseum", Reiji and Yūya began their Duel. Yūya immediately summoned the four dragons on his first turn, and successfully coordinated his heart with them to survive each of Reiji's three consecutive attacks on the next turn by having "Starve Venom", "Clear Wing", and "Dark Rebellion" take him where the Action Cards were and even managed to inflict damage on Reiji in the process. Yūya thanked the dragons for their assistance and was happy how they have finally able to fully understand each other. The happiness reminded Yūya that Zarc had also felt the same way, wanting to entertain audience, his opponents, and monsters alike. However, the audience's demands for brutal duels caused him to fall to the wrong path that led him to become a demon. Yūya cried as he finally realized that Zarc's true wish wasn't to destroy the world, but to make people smile with his Dueling. Sensing the same feeling, Zarc's soul within Reira cried as well. Reiji challenged Yūya to put that wish into practice by making him smile. Using his Magic Card, "Contract with Demon World Insurance" to draw and activate his three Magic Cards "DDD Fusion", "DDD Synchro", and "DDD Xyz", summoning "DDD Ultimate Doom King Purplish Hell Armageddon", "DDD Ultimate Doom King Whitest Hell Armageddon", and "DDD Ultimate Doom King Darkness Hell Armageddon", his three strongest DDD monsters. Using "Whitest's" effect, Reiji destroyed "Starve Venom", "Clear Wing", and "Dark Rebellion", and soon after destroyed "Odd-Eyes" as well. Yūya once again asked for his counterparts' support and managed to draw "Odd-Eyes Fusion Gate" to perform Pendulum Fusion summon using "Odd-Eyes" and "Starve Venom", summoning "Odd-Eyes Venom Dragon". Even after using its effect to overpower it, Yūya still failed to destroy any of his monsters due to Reiji's counter effect that instead destroyed "Odd-Eyes Venom". However, Yūya then used the Magic Card's effect to activate "Odd-Eyes Synchro Gate" to Synchro summon "Odd-Eyes Wing Dragon", and later followed by purposely letting the dragon got destroyed to activate "Odd-Eyes Xyz Gate" to Xyz summon "Odd-Eyes Rebellion Dragon". By banishing the three Magic Cards, Yūya not only increased "Odd-Eyes Rebellion's" ATK, but also able to attack three times. However, "Purplish's" effect prevented the "Ultimate Doom Kings" to be destroyed as long as the Xyz-Pendulum monster is still standing on the Field. Reiji once again destroyed "Odd-Eyes Rebellion", leaving Yūya without any monster and no card in his hand. Yūya used the Trap Card he has set to negate the damage and then placed "Odd-Eyes Rebellion" in Pendulum Zone before using its Pendulum effect to place "Entermate Five-Rainbow Magician" in the other Pendulum Zone to summon back his Pendulum Monsters. Yūya then used "Five-Rainbow Magician's" effect to not only make all monsters on the Field's ATK to 0 but also preventing both himself and Reiji from using Trap and Magic Cards until either of them set five cards on the Field. Yūya and Reiji began racing for Action Cards, trying to set five cards first before the other. As they were running around the Field looking for Action Cards, Zarc inside Reira started to reach out for the Duel and so does the audience. Ray, whose body was unresponsive within the ARC-V Reactor, started to react to the Duel. As both Yūya and Reiji set four cards and only need one more, both of them tried to reach the necessary fifth Action Card. Yūya got the fifth Action Card and set it first, doubling all of his monsters' ATKs and prevented Reiji from setting any card. With his monsters' ATK now above Reiji's "Ultimate Doom Kings", Yūya attacked them. Reiji sent a monster to his Graveyard to finally set give cards and doubling his monsters' ATKs above Yūya's and returned "Odd-Eyes Pendulum's" ATK to normal. Already anticipating this move, Yūya banished the monsters in his Pendulum Zone and destroyed all set cards on both his and Reiji's Field, returning their monsters' ATKs to normal. Furthermore, "Odd-Eyes's" ATK is increased for every Pendulum Monster on Yūya's Field. Despite unable destroying Reiji's monsters, Reiji still took damage and "Odd-Eyes's" effect doubled the damage he received, defeating Reiji. Following Yūya's victory, Zarc's soul was finally pacified as Reira's laugh was heard throughout the whole dimensions from the monitor. Winning the Duel, Reiji announced to everyone that Yūya has passed the pro test, officially making him a Professional Duelist, much to everyone's joy. Ray's body and soul inside ARC-V Reactor suddenly shine and transported herself, her father, and Yūya's family and friends across dimensions into the Maiami Stadium in Pendulum Dimension. Yuzu then emerged from the light with her counterparts all now residing inside her body like Yūya did with his counterparts, finally reunited with Yūya as he and everyone happily welcomed her back. Yūshō then appeared and said that becoming a Pro Duelist is not the end, but the beginning of the fun itself before he challenged his son to a Duel. Yūya accepted his father's challenge, declaring he will continue bringing smile with his Dueling and surpass his father as an Entertainment Duelist, stating his usual catchphrase that the fun has just begun.
