Lancers

The Lancers (ランサーズ Ransāzu) is an elite group of Duelists in the Yu-Gi-Oh! ARC-V anime formed by Reiji Akaba to defend the Standard Dimension from the Fusion Dimension in an effort to save it from the same tragedy that had fallen the Xyz Dimension.

Pre-Maiami Championship
Reiji Akaba used a database of Duelists called the Lancers Selection to narrow down his candidates for inclusion in the group.

Battle Royal
Reiji used a database of Duelists called the Lancers Selection to narrow down his candidates for inclusion in the group. The Maiami Championship then became a proving ground for the formation of the group. When the top eight Duelists in the tournament's Youth Division were determined, Reiji inducted them into the Lancers. Knowing an attack from the Fusion Dimension was coming, Reiji dispatched those eight Duelists to confront the Obelisk Force when they arrived to capture Serena and interfere in the Battle Royal of the Junior Youth Division. Six members of the Obelisk Force were confronted by these eight Duelists, led by Yū Sakuragi. However, all of them were swiftly taken down except for Yū, who was saved by Yūgo. According to Reiji, the current Lancers lack the strength to combat Academia. Since the discovery of Pendulum Summoning, Dueling evolved to a new era, which Reiji dubs "Yūya Sakaki's generation". He plans for this new generation to master Pendulum Summoning to combat the invaders more efficiently.

After  Shingo Sawatari  demanded to see Yūya Duel during the invasion, Reiji decided to make Shingo the first of his new Lancer team and sent him to aide the remaining Duelists against the  Obelisk Force.

When the Battle Royal ended, Reiji appeared before the survivors and explained his plan and the overall situation. This enraged Yūya, who refused to join the Lancers and attempted to attack Reiji. Reiji suggested they settle it with a Duel instead. Reiji won the Duel, and concluded that Yūya was too naive. He maintained his hopes for Yūya, however, and declared that the Lancers would soon travel across Dimensions.

Aftermath
Later, Reiji and Himika cancelled the Maiami Championship to reveal the Lancers' existence to the world as well as their recent victory against the Invaders. The Lancers were acclaimed as heroes by the world, and Reiji declared that LDS would switch all of its efforts to training Duelists to become potential Lancers.

Departure
After Yūya's Duel with his mother, he and Gongenzaka were called by Leo Corporation. When they arrived, they saw the other Lancers gathered inside. Reiji announced that they were having a new member, Reira. Shingo and Shun were both skeptical about Reira being be a threat to their plans, since he was a child and must always be protected. Reiji responded that Reira's ability was almost "equivalent" to the Lancers. Then, after learning that Yuzu was in the Synchro Dimension, Dennis expressed surprise that she survived. Reiji also announced that they were going to the Synchro Dimension to make an alliance with it, as that dimension has never been into wars. Reiji said that the Lancers' Duel Disks were now modified to be able to travel between dimensions and activate Action Field Magic Cards and Action Cards, which were the strongest weapons against the invaders. The Lancers then left the Standard Dimension with their "Dimension Mover" cards and traveled to the Synchro Dimension. Somewhere before their departure to the Synchro Dimension, Reiji created and distributed Pendulum Monsters to the Lancers that fitted their specific Decks. These were at least distributed to Dennis, Serena and Gongenzaka , who didn't own deck-specific Pendulum cards before.

Duel Against Securities
Upon arriving at the Synchro Dimension the Lancers were split. Yūya, Serena, Shingo, and Reira were ambushed and almost arrested by Security because they mistook Yūya and Serena for Yūgo and Yuzu, respectively. Serena and Shingo immediately joined the Duels the Security forced them into, despite Yūya's protests that they just got to the Synchro Dimension and that they should run. Shingo lost and was held in custody by the officers, while Serena won her Duel. In his Duel, Yūya indirectly tipped the Security officers to the use of Action Cards, which frustrated Shingo, who then clarified the mechanic to them. Before Yūya's Duel could continue, Crow Hogan and a group of Riding Duelists rescued the Lancers from the Security's clutches.

Underground Riding Duel
Gongenzaka and Dennis attempted to find the others until they ended up Dueling each other and were approached by Gallager. Gallager took them to an underground area where they found Shun Dueling and subsequently defeating Mukuro Enjō. Shun told his fellow Lancers that he was doing underground Duels so he could recruit more Lancers. Gallager was surprised that Shun knew both Dennis and Gongenzaka, so he decided to pair Shun and Dennis up for a Duel, as he had a good feeling about the latter. As Shun was the current champion, he was given a 1000 LP handicap, while Dennis was given the default 4000. Both of them avoided game-ending damage with "Necro Raptors" and "Pinch Breaker", respectively. Meanwhile, Serena grew impatient with Crow's lack of news about Yuzu and Yūgo and left the hideout to search for the former, ignoring Yūya's and Crow's warnings. Shingo decided to accompany her.

Before Shun and Dennis could continue their Duel, their D-Wheels were shut down by Security, causing them to tumble to the ground and be arrested by the Security officers. Gongenzaka and the non-Tops residents were arrested as well. Elsewhere, Serena Dueled and defeated eight Duelists. Shingo questioned her actions because searching for Reiji and Yuzu was their priority, and she clarified that she was doing this to recruit more Lancers. They returned to Crow's hideout, where they witnessed Yūya and Crow Dueling each other because of a childish argument involving making Reira happy; Yūya believed that Reira simply had to smile, while Crow believed that Reira having food to eat was enough. Unknown to Shingo and Serena, Security had followed them to the hideout. Officers sprang out and arrested the Lancers and Crow. Tsukikage arrived at the hideout to rescue Reira, not before making eye contact with Serena.

Friendship Cup, Day 1
After the captured Lancers were sent to the Facility and escaped, they were again captured by Security and brought before the Executive Council. There Yūya and Shingo declared the Lancers goals and were defended by Reiji who had been with the council with Reira and Tsukikage. The head of the Security, Jean-Michel Roget, decided to have them take part in the Friendship Cup to test the Lancers strength and to have Yūya face off against Jack Atlas in an exhibition match to which the Lancers agreed to. After Yūya's loss, he and the other Lancers faced off in the Friendship cup with Gongenzaka and Tsukikage losing their Duels and Serena winning hers in the first day. The next day Yūya faced off and mercilessly defeated Duel Chaser 227 after envying the Awakened state. Shingo then faced off against Yūgo and nearly defeated him but was defeated after Yūya's mind synced with Yūgo's which allowed him to survive with an Action Card and defeat Shingo. The last match featured Shun vs Dennis where Shun manage to expose Dennis's true nature and allegiance to Academia. After Dennis revealed he helped the Fusion Dimension invade the Xyz Dimension and capture Ruri Kurosaki, Shun mercilessly defeated Dennis while an angry Yūya, Yūto, Yūgo, Crow, Shinji, and Serena watched in discontent at Dennis's betrayal and Shun's anger.

Friendship Cup, Day 2
After Dennis and Shun's Duel, Roget overthrew the Executive Council, sealing their authority by perfecting his control over the Security officers using mind-controlling chips implanted in them. The Lancers no longer had to prove themselves to the Council and became part of Roget's schemes in expanding his influence over the City. Roget gained an interest in both Yūya and Serena. Serena would become an idol for the Tops and Commons alike, while Yūya would serve the same role as Sergey Volkov; defeating Jack Atlas and vesting a King that served Roget, a role Roget went on to force Yūya into the same way he did with Sergey. Sealing the Council away effectively sealed Reiji and Reira Akaba, who were with the Council during the Cup, preventing Reiji from exerting any leadership over the Lancers via Tsukikage.

In the second day Duel, Yūya was able to defeat Shinji, but Roget's approach after his victory misled Shinji and the Commons to think that Yūya cheated and was in league with Roget and Tops. Yūya escaped from the Duel Palace to meet with Sora, who had revealed his presence to Yūya during his match against Shinji. Both tried to convince each other to do what they said, but none was willing to do. The Security that Roget had sent captured Yūya who protected Sora, while the latter escaped to protect Yuzu who was also being targeted. The next match pitted Shun against Crow, leading to Shun's lost. Meanwhile, Roget tried to win over Yūya to his side, but Yūya refused and was thrown into solitary prison.

The next match was Serena vs Yūgo. Despite Roget's interference with the courses to ensure Serena's victory, Yūgo won the match thanks to his synchronisation with Yūya increased his Duelling skill. This left Yūya as the only member of Lancers in Friendship Cup. When Roget's Security officers were distracted watching the conclusion of Yūgo and Serena's Duel, Reiji seized the opportunity and challenged and defeated the Security officers holding him, Reira and the Council. Reira hurried to the Underground's entrance and saved Serena from Security before she could be taken and then they escaped with Tsukikage's help. This infuriated Roget, who saw his schemes being destabilized and his hatred for the Lancers deepened.

Academia Invasion
After Yūya's duel with Crow, the Obelisk Force arrived to capture Yuzu and Serena. Yūya escaped from the Duel Palace and arrived to Reira and Serena's location just as Reira began to collapse from exhaustion. Summoning "Odd-Eyes Pendulum Dragon", "Dark Rebellion Xyz Dragon", and "Enlightenment Paladin", Yūya swiftly and easily defeated the Obelisk force and began a Duel with Barrett to protect Serena and Reira. Meanwhile, Tsukikage went off to the underground to retrieve reinforcements but was intercepted by the Obelisk force. Ganging up on him, the Obelisk force nearly defeated him until Sora arrived and, with Tsukikage's help, defeated all the Obelisk force dueling him. While Sora went to where Reira and Serena were, Tsukikage proceeded to the underground where the remaining Lancers were. Arriving there, he gave the Lancers their Duel Disks during a prison outbreak led by Shinji and the Commons. Shun and Shingo dueled together against 5 security guards and managed to win before being surrounded by the Arrest Corps. Thankfully, they were saved by Damon using conveyor belts to send them away. As Yūya struggled against Barrett, Sora, Yūri, more Obelisk Force soldiers and Yūgo arrived in rapid succession. Yūya and his counterparts then entered a synchronized awakening caused by the Four Dimension Dragons that opened a dimensional hole in the sky, only breaking when Yuzu arrived, transporting both Yūri and Yūgo. Sergey then arrived and, profiting from the occasion, easily defeated Barrett. Nevertheless, Barrett managed to take Serena back with him using the last of his power. With Serena being taken back, Sergey then engaged a Duel against Yūya who tried to protect Yuzu. Unfortunately, his Duel against Barrett left him at huge disadvantage, leading to his defeat at Sergey's hand who then took Yuzu to Roget.

Commons Rebellion
While resting after the Duel last night, Yūya, Tsukikage, Sora, and Reira were found by Shingo, Gongenzaka, and Tokumatsu. Meanwhile, Shinji and the other Commons began to rebel against Tops who were seeking refugee at Duel Palace, causing riot throughout the whole City. To calm down the situation, Roget proceeded with the second round semi-final match, disqualifying Yūgo who was absent and replaced him with Sergey to Duel Jack. Worried for Yuzu, Sora and Tsukikage agreed to go together to save her, which later followed by Yūya and Gongenzaka while Reira, Shingo, and Tokumatsu went to where Reiji was.

Frienship Cup, Day 3
The Duel between Jack and Sergey made the Commons to momentarily cease their rebellion and focused their attention to the Duel. After Jack was victorious against Sergey, the Commons proceeded with their rebellion. Having lost his trump card and desperate, Roget declared a martial law, furthering the chaos and increased the hostilities between Security and Commons. Having enough watching, Reiji finally confronted all Security outside, destroying their trap and spell cards. Reira, Shun, Shingo, and Tokumatsu who arrived there, also helped in defeating the Security. At the Commons area, Yūya got a message from Jack that was delivered by Sam that prompted him to go to Duel Palace to Duel Jack in hope it will stop the riot and saved the City, but having difficulties to reach there due to the riot. Frank, Amanda, and Tanner then found him and led him through their shortcut to Duel Palace. Arriving at the entrance of Duel Palace, they were intercepted by the rebelling Commons who mistook them as Tops seeking refugee. Fortunately, Reiji, already figured that Yūya will go there, arrived while riding on Shun's Raid Raptors along with the rest, and helped them entering Duel Palace by flying on the monsters. Yūya then declared that he will Duel Jack to show everyone the Duel that he believes. The Duel Chasers ambushed the Palace to stop the final match, but the Lancers and Tokumatsu easily defeated them all. While Yūya was duelling against Jack, the remaining Lancers watched on until they heard Melissa announcing the Commons outside Duel Palace once again attempting to continue their attacks on Tops. Knowing the worst if the chaos is left to continue, they Lancers split up to stop the chaos: while Reiji and Reira headed to face Roget at Public Security Maintenance Bureau, Shun, Gongenzaka, and Shingo stop the Commons from further advancing their attacks. Yūya's Dueling earned the attention and support from the whole residents of City, and eventually his victory against Jack put a stop to all hostilities between both sides for good, uniting them together. The result of the Duel led the Executive Council to retire and abolish the social class system that separated Tops and Commons. Their celebration was cut short when Sora revealed through the broadcast room that Roget has recaptured Yuzu with intention to take her to Academia as bargaining chip, prompting the Lancers to go to Public Security Maintenance Bureau.

Final Confrontation Against Roget
Meanwhile, Reiji and Reira regrouped with Tsukikage and confronted Roget who still refused to admit defeat. He lured Reiji to a room and trapped him there, Reiji having pushed Reira away before the door closed. Roget decided to take him to Academia as well in hope it would pleased the Professor and the two started Dueling. The other Lancers and Sora eventually got inside through hacking the system, where Reiji then set up a combo to block Roget's cheating ways. Following him while he escaped with Yuzu, Yūya mangled to save Yuzu with Jack and Crow's help who have expected Roget's escape plan. Roget eventually broke down mentally and activated the dimension travel device to send the whole City and everyone within it to the void between dimensions along with himself. The device malfunction, however, creating a wormhole that sucked Roget instead. After getting sucked in himself, another wormhole appeared and sucked in Yuzu, Yūya, Shingo, Gongenzaka and Shun. While Yuzu's whereabouts is unknown, Yūya, Shingo, Gongenzaka, and Shun were warped into the Xyz Dimension's Heartland City while the remaining Lancers at Synchro Dimension were left wondering what happened, dividing the Lancers further.

Duel Against Kaito
In the Xyz Dimension, Shun immediately left the other three to check on the Resistance, which seemed completely annihilated. The other three met a surviving refugees who revealed that there has been no sight of the Resistance and assumed they were already destroyed. When threatened by three Academia students hunting down survivors, Yūya and the others demonstrated how fun Dueling could be with Pendulum Summon and "Smile World", rather than the warfare the Academia showed them, defeating the Academia students. While Yūya stopped Shingo from using their own Duel Disks to seal Academia students into cards, the trio fled, but were instead carded by a Resistance Duelist, Kaito Tenjō. Realising that Kaito mistook them as Academia Duelists, Yūya and Gongenzaka tried to explain they are not from Academia let alone his enemies, but the distrustful Kaito challenged them to Duel to determine whether they are his enemies or not. Shingo and Gongenzaka Duels him, while Yūya watched with Yūto who uncovered Kaito's background. Despite their best efforts, Kaito defeated them, leaving Yūya has no option but to fight to protect his friends from being carded and hoping able to convince Kaito that they are allies. Their Duel was interrupted by Shun who arrived with Allen Kozuki and Sayaka Sasayama, clearing the misunderstanding. Despite Shun's assurance, Kaito still refused to join with them and left.

Discussion Between Resistance and Lancers
At the Resistance's hideout, Allen and Sayaka explained the whole situation while Shun and Yūto were gone: Academia had launched a massive attack that destroyed the majority of their Spade and Clover branches Duelists and also most of the residents. The casualties included Kaito's whole family, which was the reason behind Kaito's drastic change of behaviour and his separation from the Resistance. Hearing that Yūya was Yūshō's son, they also revealed that Yūshō was their teacher, but suddenly disappeared during the invasion and they believed he had abandoned them out of fear.

Yūya vs. Edo Phoenix
Wanting to clear his father's name, Yūya goes to search for him while conversing with Yūto about the phenomenon involving their dragons and an unknown being inside them. Yūto deduced that the phenomenon was the cause why they were able to converse normally and his presence in Yūya's body was according to "Dark Rebellion Xyz Dragon's" will. Yūya then encountered an Academia Duelist who had a grudge against Yūshō and was also looking for him, Edo Phoenix. Hearing of Yūya's blood connection with Yūshō, Edo challenged him to a Duel, planning to defeat and make Yūya a bait to lure out Yūshō. The two Dueled fiercely against each other, though Yūya's attempt to speak with Edo through Duel to find out about his father allowed Edo to lead the Duel to his favour. Edo's Spell card and monster effect also gave Yūya, who was using "Dark Rebellion", a disadvantage as Xyz monsters were immune to its effect. Unable to hold on his rage, Yūto forcefully took over Yūya's body and countered attack by performing Rank Up Xyz Summon. Summoning "Dark Requiem Xyz Dragon" and using its effect that negated Edo's monster's effect, they were able to force Edo to end the Duel with a draw. Before Edo being fetched by his subordinates, Yūya learned that Edo is the Commander-in-Chief of Academia.

Shun vs. Kaito
Shun confronted Kaito who still refused to come back to Resistance and challenged him to a Duel. Understanding Kaito's sadness after losing his family was similar with his own when he first heard of Ruri's kidnap, Shun tried to remind Kaito of their bonds as fellow members of Resistance and taught him the importance of their allies, something that Shun learned during his battle at Synchro Dimension. Kaito remained adamant, stating that when they lose their allies, they will experienced deep sorrow and since then viewed allies and such as nothing but a burden to him. Shun retorted that precisely because he doesn't want to lose his comrades he's fighting with them and he was carrying the will of those who perished. Watching Shun trying to convey his feelings for the first time, Yūto and Yūya revealed to everyone they were sharing a body, something that didn't shock Shun who already had a hunch of Yūto's presence nearby. Shun tried to overpower Kaito's overwhelming "Galaxy-Eyes Cipher Dragon" by continuously using Action Cards. Unfortunately, despite Shun's best efforts, he was eventually defeated by Kaito. When he was about to be carded, Sayaka tearfully begged Kaito to spare Shun as she revealed her regret for unable to help Ruri when she was kidnapped right in front of her. Hearing this, Kaito relented to Sayaka's request and left.

Duel Against Tyler Sisters
A Tag Duelists from Academia, Gloria Tyler and Grace Tyler, infamously known as Tyler Sisters, arrived at Xyz Dimension under Leo's order to wipe out the Lancers. They encountered and defeated Allen, Sayaka, Shingo, and Gongenzaka. Yūya and Shun, who arrived shortly after Shingo and Gongenzaka were defeated, accepted the sisters' challenge for a Tag Duel. When the sisters explained the rules of the Tag Duel, Yūya realized why Shingo and Gongenzeka lost easily, they shared a graveyard which was detrimental to Gongenzeka's deck. The sisters easily overpowered Yūya and Shun by using the combinations of their Spell cards that increased their LP for each special Summoned monsters by Yūya and Shun and negated their battle damage. The situation worsened when both Shun and Yūto quickly let their anger get the better of them as they recognised the sisters as the ones responsible for nearly annihilating the Spade Branch, resulting Shun making careless moves that only increased the sisters' LP. Fearing he will be taken over by the mysterious being again if he let Yūto being controlled by his anger further, Yūya told Yūto and Shun to calm down and trust him. Using his own combination of spell cards and monster effects in Entertainment Dueling style, Yūya and Shun able to defeat Tyler Sisters, reducing their entire LP with one attack.

Yūya, Shun, and Kaito vs. Obelisk Force
While on their way back to hideout, they were intercepted and challenged by the Obelisk Force. Because the others were still injured, Yūya and Shun were the only ones who Dueled the Obelisk Force. Yūya and Shun easily outwit the Obelisk Force with their teamwork, but they were driven into corner when one of them summoned "Antique Gear Chaos Giant", triggering Sayaka's trauma of the first attack and she fled in fear. "Chaos Giant" caused a debris to fall above Sayaka, prompting Shun to protect her. This came at the cost of him being badly wounded and collapsed, leaving Yūya alone to fight. Kaito arrived in time to help Yūya and easily defeated the three Obelisk Force by himself.

Yūya vs. Edo & Kaito vs. Academia Squad
Shortly afterwards, however, Edo arrived with his squad, surrounding Yūya and the others. Yūya got dragged by Edo who chained their Duel Disks and then trapped them in his magic field to prevent Yūya from escaping or anyone interfering with their Duel. With great reluctance, Yūya accepted Edo's challenge while Kaito Duel the entire squad alone to protect their injured comrades. Kaito easily defeated the squad alone and then took Shun back to hideout with the others, assuring Yūya to focus on his Duel against Edo. Yūya was quickly cornered by Edo's monster effect and spell combo, but after hearing Edo's story about what happened between him and his father, Yūya came into realization that Edo was conflicted between his loyalty for Leo's teaching and the newfound feeling from his Duel against Yūshō, and the Commander-in-Chief was in a state of self-denial. Realizing this, Yūya made his come back using his Entertainment Dueling that slowly managed to open Edo's heart. Using "Smile World" and "Entermate Laughmaker's" effect, Yūya revived his new Fusion monster, "Brave-Eyes Pendulum Dragon" and used it to defeat Edo. Unfortunately, Yūya didn't have time to celebrate as another Academia squad called by Noro arrived and surrounded him.

The Academia's Defection
To everyone's shock, Edo defended Yūya and declared his betrayal, which followed by the Tyler Sisters who also decided to join Yūya and the Lancers, being convinced to do so after watching Yūya's Entertainment Duel. Noro was also forced to surrender when Kaito and Allen returned with their Resistance comrades to assist Yūya, the Vice-Commander unable to fight back because he wasn't a Duelist. Edo then convinced the remaining Academia soldiers to abandon ARC Area Project and instead help in rebuilding Xyz Dimension. The three sides then returned to Resistance hideout where the former Academia soldiers helped the refugees by distributing foods and medical supplies for free. While the former Academia were busy helping the refugees, Yūya and the others were discussing their decision to let the former Academia soldiers helping them even after what they have done. Allen, in particular, was suspicious of their intention and doubting their sincerity, especially towards Edo who was the Commander-in-Chief of the invasion. Yūya, Yūto, and Kaito convinced them that Edo has truly regretted for what he had done and that's why he came to atone for his sins. Edo interrupted their discussion, revealing there's a way to return all the carded people back to normal.

Departing to Fusion Dimension
Edo explained that all carded people, without any exception, were sent to Academia through the dimensional transfer device in their Xyz Dimension headquarter since the carded was said will be reborn once the ARC Area Project is completed. Under Sayaka's urge, Yūya, Kaito, Shingo, and Gongenzaka decided to go to Fusion Dimension to retrieve all the carded people while Edo, Sayaka, Allen, and the others stayed to continue helping the refugees and tending Shun's injuries.

Yūya vs. Isao
Once arriving in Fusion Dimension, Yūya and the others found Yuzu being cornered by the Academia forces led by Dennis. Yūya was pinned by Isao Kachidoki, the Duelist Yūya had defeated in the second round of Maiami Championship and was forced to accept his challenge for a rematch while Yuzu was protected by Gongenzaka and Shingo, and Kaito chased after Dennis. Learning from his previous Duel, Isao summoned his new Fusion monster, "Shura the Supremacy Star", that increased every monster's ATK with level 5 above, but won't increase Yūya's "Dark Rebellion" since it doesn't have a level. Yūya was able to counter this by using "Antithesis Magician" and "Synthesis Magician's" Pendulum effect to give it level and changed it into the same level as "Shura". The clashing counterattacks led the two Duelists to look for Action Cards, with Yūya this time able to evade Isao's attack by using the roller skates given by Allen. Yūya eventually cornered Isao by placing his monsters to the graveyard with his monster's effect. Refusing to accept another defeat, Isao attempted for a draw, but Yūya used his trap card "Acrobat Tower" to determine their victory by the amount of their monsters' level in the graveyard and the ones they draw. Yūya able to draw two monsters with lower level, allowing him to defeat Isao. The applause from the bystanders who were watching the Duel made Isao realized that Entertainment Duel wasn't as bad as he thought, which he admitted to Yūya before leaving.

Yūya & Sora vs. Captain Solo
Yuzu took Yūya and the others to the harbor where Yūshō was, but arrived too late as the ship sailed off, prompting them to look for another ship or boat. Serena then appeared and led them to a pirate ship led by Captain Solo, telling them she was able to escape not long after being recaptured by Barrett. En route to Academia, however, Academia helicopter arrived and Serena assisted them in capturing Yuzu, taking her to the helicopter, leaving Yūya, Shingo, and Gongenzaka must face Solo and his crew who were in league with Academia. While Shingo and Gongenzaka were tied by Solo's crews, Yūya Dueled Solo whose monster effect prevented Yūya from summoning any of his monsters from his hand, forcing him to rely on Action Card. Unfortunately, Solo's dirty play prevented Yūya from getting any Action Card and when he finally got one, the effect was a self-damage. During the Duel, Yūya got thrown from the ship by Solo's crew, but was saved by Crow who came with the remaining Lancers by boat. Crow saved Yūya by summoning "Raikiri" before he fell into the sea, while Tsukikage freed Shingo and Gongenzaka from their bind, gathering them at the Lancers' boat. Solo directly attacked the boat they were riding with his cannon just as he direct attacked Yūya, but Reiji successfully evaded each of the cannon. The direct attack reduced significantly Yūya's LP, so Sora decided to join the Duel. Already knowing "Captain Lock's" effect, Sora summoned his Fusion monster "Death-Toy Piton Kraken" from his extra deck and then supported by Yūya's trap card, "Entermate Big Support" that increased its ATK, the two were able to defeat Solo.

Before leaving, Tsukikage has tampered with a part of Solo's ship, preventing him and his crew from following them. Reiji and Crow then explained what happened after Yūya and the others disappeared from Synchro Dimension, and Yūya expressed his belief that Serena captured Yuzu not because of her own will, something that Sora confirmed, revealing that he had heard there is someone who can control people's heart and mind in the Professor's inner circle. With this knowledge, the Lancers determined to end the Academia's tyranny.

Heading towards Academia
As the Lancers continued their journey to Academia, Yūya discussed about Yuzu, Serena, Ruri, and Rin, and asked Sora why does the Professor wants them. Sora suggested that they might be connected to the ARC Area Project and Gongenzaka deduced that if they rescued the girls first, the Project would be stopped. Yūya also told Reiji that his father is heading toward Academia to convince the Professor and they were trying to go after him. Surprised, Reiji would then reveal to everyone how he secretly went to Academia three years ago and had asked Yūshō for help after learning about his father's plan. However, Yūshō used his Interdimensional Travel Device without telling anybody and disappeared. He also met Serena and after meeting Yūya and Yuzu three years later, a memory resurfaced from Leo's research: Revival Zero. In it contained a file with two people, Serena and Yūri, who resembled Yūya. He told Yūya that his theory about the Four Dimensions and four girls connected to the Arc Area Project was probably correct, and he deduced that Revival Zero was another part of Leo's plan and that Yūya was probably involved due to Yūri's involvement. Reiji told the Lancers to believe in their friends' strength and fight to the very end. After arriving on the island, they prepared to climb the mountain to charge into the Professor's lab.

Survival duel
After climbing up the mountain, they were surrounded by Academia students before utilizing their plan to spilt two groups with Yūya, Gongenzaka, Shingo, Crow, and Tsukikage Dueling the students while Reiji, Reira, and Sora continue to the lab. When the students retreated, they chased after them but had fallen into a trap and were captured in energy nets. They were then forced into a Survival Duel with five Academia students that would only leave one man standing. While the Lancers argued about participating, Tsukikage went ahead to provide reconnaissance. However, they heard a scream and ran to the location only to find a Academia student carded and another student in the bushes scared. Shingo and Crow chased after him while Yūya and Gongenzaka were separated from them. Meanwhile, Tsukikage Dueled an eleventh Duelist who attacked both groups alike and was outmatched. Before he was about to be defeated, Tsukikage left a message on a tree for his comrades and was sealed into a card. Yūya and Gongenzaka would hear Tsukikage's scream and ran to his location only find him carded and his message revealing that there's an eleventh Duelist in the forest with them. Shingo spotted someone staring at him from the bushes and screamed, alerting Crow who ran to his location. Yūya and Gongenzaka found another student carded and they hurried to find Shingo and Crow fast due to the danger of staying separated. Shingo ran away from his pursuer until falling off the Duel arena and landed on a cliff. He climbed back up while reuniting with Crow, who noticed someone was watching them until two more students arrived. Thinking they were his pursuers, Shingo and Crow challenged them to a Duel, but before he could take the first turn, someone intruded the Duel and Crow called out for that Duelist to revealed their self. After the two students were sealed into cards, Crow continued to call out for the Duelist to revealed themselves. While he and Shingo ran, Crow realized they couldn't defeat the Duelist and had "Raikiri" attack Shingo directly, damaging his Duel Disk in the process, to save him from being sealed into a card. After "Raikiri" was destroyed, Crow activated "Black Feather - Last Will" in an attempt to defeat the Duelist, but failed. However, he was able to reveal the Duelist's identity, Battle Beast. Yūya and Gongenzaka were able to find Shingo and Crow due to Crow's trap, but were too late as he was sealed into a card. After learning that Battle Beast was responsible for sealing everyone into cards as well, Yūya and Gongenzaka challenged him to a Battle Royal Duel. However, they barley survived his subsequent attacks and blocked Yūya's moves to get an Action Card, forcing Gongenzaka to use one. When Gongenzaka was defeated, he was about to be sealed into a card before Jack came speeding down a entrance on the Wheel of Fortune and flew into the Duel arena, surprising everyone present. Jack joined the Duel and brought out "Red Daemon's Dragon Scarlight", pushing Battle Beast into a corner which caused Sanders to join as well. During the Duel, Yūya was shocked that the Professor wants him eliminated specifically and was part of their plan. While lost in thought, Yuya barely noticed "Gladiator Beast Tamer Editor's" attack and dodged it, with Jack telling him to express his feelings in a Duel. However, they were surprised when Battle Beast used the effect of "Tamer Editor" to destroy itself, taking Sanders out of the Duel.

Using Yūto's Deck due to his determination to save Ruri, They both used tactics Ruri knows in order to make her remember. But, after seeing her use Fusion Summon, they learned from Shun that they have to defeat the person controlling one. Shun was about to go find that person but tased by Serena, who joined the Duel.

The Origin of Four Dimensions
Yūshō questioned Leo's objective while reminding him how they worked together to bring Dueling to a new era and still appreciate their encounter. But, everyone was surprised that the Solid Vision came from the Original Dimension and how Leo brought Duel Monsters to life with it. They also learned how a Duelist, who stood at the top of the Dueling world, attacked everyone with his four dragons and fused with them into one monstrous dragon. Meanwhile, Yūya, surprised about father's past and Zarc, entered a synchronized awakening with his counterparts and destroyed the cage, which knocked out Kaito and Edo who just arrived.undefined Yūya arrived at the Professor's inner chambers and reunited with his father, who was told by Leo that Yūya isn't his son. They then saw Yuzu, Serena, Ruri, and Rin in capsules behind Leo and watched him card the Doctor. Everyone in the chambers learned how Leo's daughter, Ray Akaba defeated Zarc by using four cards to split him and his dragons apart at the cost of herself and the Original Dimension, which became the Four Dimensions. They were shocked when Leo revealed that Yuzu, and her counterparts were reincarnations of Ray due to her splitting apart and planned to reunite them with ARC-V. They even learned that Yūya and his counterparts were Zarc's reincarnations and Leo want to destroy them due to them carrying his soul. However, Yūya and Reiji refused let any of this to happen and challenged Leo to a Duel.

Yūya and Reiji vs. Leo
They brought out their best monsters and sealed Leo's Extra Deck, but were surprised when he used Pendulum. When Leo tried convince Reiji to join him, he refused and believed in Yūya. However, when ARC-V started powering up around the girls capsules, Yūya (and Yūto) awakened and pushed Leo into a corner. While watching the Duel, Yūshō thought about Zarc and discovered that Zarc sent Yūya to him in order to raise as a Duelist and encourage his awakening.undefined But, Leo countered and pushed Reiji into a corner while Yūya managed to hold his own under Zarc's influence. Reiji, Yuzu, Serena, Rin, and Ruri Kurosaki believed in him and Yūto break free from Zarc but when Leo increased ARC-V's energy input, they brought out "Odd-Eyes Raging Dragon". Using the effects of "Odd-Eyes Raging Dragon" Yūya was close to defeating Leo (and Reiji) but Yūshō stopped him with "Binding Swords of Impact", causing the Duel to be terminated due to it being defective. He then handed Reira, who passed out during the Duel, to Reiji and went to go prevent Zarc's revival.undefined

Yūgo, Yūri vs. Edo and Kaito / Reiji vs. Reira
While Yūya attempted to break free from the pillar, Reiji yelled at Leo to turn off ARC-V as his throne left the room to watch over ARC-V. Meanwhile, Yūshō ran into Edo and Kaito and told them that Yūya, Yūto, Yūgo, and Yūri are alter egos of Zarc and are trying to revive him by becoming one. They then went to go stop Yūgo and Yūri, who were Dueling at the moment. Upon arriving Edo and Kaito joined their Duel and took on Yūgo first countering each other's attacks. When Edo mentioned Rin, Yūgo started show signs of regaining his self and after battling "Destiny HERO - Duskutopiaguy" he returned. However, Yūri defeated Edo and Kaito with "Greedy Venom Fusion Dragon" and Sora could only watch Yūgo take him alone due to his injures.undefined Yūya continued to attempt to break free from the pillar after sensing Yūgo and Yūri were near. Reira challenges Reiji to a Duel in order to help Ray after being contacted by her. Reiji sealed away most of Reira's tactics but was surprised at how Reira continued to push off. With Ray by his side, Reira managed to turn the Duel his way and brought out a monster Reiji never saw before. As Reira destroyed his monsters one by one, Reiji wondered where he went wrong and that he created a monster. Meanwhile, Yūshō hope for Yūgo to endure so Zarc won't resurrect but was surprised when Yūri defeated him.undefined
