Yūto

"I don't want to hurt anyone anymore."

- Yūto's vow to himself after watching many people got hurt.

Yūto (ユート) also known as Ute, is a main character of the Yu-Gi-Oh! ARC-V anime. He has three dimensional counterparts: Yūya Sakaki from Standard Dimension, Yūgo from Synchro Dimension, and Yūri from Fusion Dimension. He works with Shun Kurosaki to search for Ruri Kurosaki whom has been kidnapped by their enemies. He and his Counterparts are the reincarnations of the Demon Duelist Zarc.

Appearance
Yūto strongly resembles Yūya Sakaki; people often confuse him with Yūya, and the first time Yuzu Hīragi saw him, she thought he was Yūya in a costume. Yūto and Yūya have nearly identical faces, except for their eye colors (Yūto's eyes are gray, while Yūya's are crimson). His hair is close to a palette swap of Yūya's, black in the back with light purple in the front. Unlike Yūya, whose hair lies flat, Yūto's sweeps upward and to the right side of his head.

He wears a punk-style outfit, with a dull green formal shirt and dark blue tie, as well as a black cape-like garment with ripped sleeves and edges plus dark blue pants and black boot-like shoes. Like Yūya, Yūto also wears a choker and wristbands, although his bands are a matching set—black with silver studs. Yūto also shares Yūya's penchant for goggles, though his are of a sharper make and a more military style. He also sports a mask he uses to conceal his face, a red scarf tied around his upper right arm that is partially hidden by his sleeve, and can sometimes be seen with a larger red scarf around his neck. He abandons the goggles entirely after they are damaged in his Duel with Shingo Sawatari, and later gets rid of his mask as well.

Yūto and his dimensional counterparts' attire and hair are all based on the color of the cards that their dimensions are based on. As such, Yūto wears dark clothing to reflect the color of Xyz Monsters, while his hair is both black and purple, the latter color likely a reference to the color of DARK Xyz Monsters' Overlay Units.

Personality
Yūto and Yūya are similar in that both care about their friends and do not want to hurt anyone; this is shown by his reluctance to let Yuzu be involved in his fight. However, while Yūya is energetic and positive, Yūgo is short-tempered and stubborn, and Yūri is cruel and sadistic, Yūto is cold, serious, calm and collected. Even more so than his Dimensional counterparts. He has hardly ever losing his calm, only ever done so when he is with his two close friends, Shun and Ruri, particularly when he is with Ruri whom he has feelings for.

As a Duelist experienced in dimensional war, Yūto is battle-hardened, telling Shingo that he doesn't feel the sharpness of a sword nor the power of a bullet from his Dueling. Unlike his best friend Shun, he is not reckless nor impatient in his mission. Instead of simply attacking anyone he assumes to be an enemy, he would first interrogate them to get a clear idea of the situation, then leave them alone should they not be a real threat. His perceptiveness made him quick to deduce that most of LDS in the Standard Dimension is unaware of the war between Academia and the Resistance.

Yūto is actually a conflicted individual. While he has strong hatred for his enemies, t he destruction of his home world and losing many of his comrades made him developed a strong desire to not hurt anyone, but at the same time he knows that he must continue to fight to protect and save his comrades. Thus, he shows mercy against enemies who are at a disadvantage, such as when he offered a recuperating Sora the chance to surrender during their match after holding back against him on purpose.

Deep inside his heart, Yūto harbors a deep vengeful hatred towards the Fusion Dimension and the Academia for the destruction of his home world. While indirectly possessing Yūya, he doesn't care of the consequences resulting from his actions and only focuses on defeating his enemies. This is worsened when he was under the influence of the unknown darkness to the point he enjoys harming them. Once returning to Heartland, Yūto began to be more overwhelmed by his anger and hatred that unlike before, he no longer hesitates in defeating his opponents in harsh way and for the first time clearly showing his contempt for Academia to the point of ignoring Yūya's feeling and pushing aside their ideal.

Etymology
In the anime, Yūto's name in Romaji is written as "Ute", which is pronounced as "Yūto" in Japanese. Yūto has many definitions depending on the kanji used. For example: 優 (Yū) means "Gentleness" and "Superiority", 悠 (Yū) means "Distant" and "Leisurely". The last syllable 人 (To) means person, 翔 (To) means to "Soar" or "Fly". For this character, his name is written in Katakana, so it has no actual meaning.

History
Yūto is from Heartland City of Xyz Dimension with his close friend Shun Kurosaki. Together with him, Yūto attended the Spade Branch of Heartland Duel School. During a Duel in their school, Yūto was impressed by the girl who won the Duel, whom Shun revealed to be his littler sister, surprising Yūto who couldn't find any resemblance between them. He was then introduced to the girl, Ruri Kurosaki, and fell for her at first sight, which Ruri mutually returned. The two grew closer as they spend much times together, often sharing knowledge of their decks and the two eventually seemed to be in a relationship, sharing an intimate moment together. At one point during these times, they watched a Duel in which Kaito Tenjō, the ace of Clover Branch, their rival branch, was Dueling, and like everyone else were amazed by his Dueling that Yūto commented as dynamic yet delicate, and expected him to become Heartland's Duel Champion. Their happy lives ended when one day, their homeland was invaded by the Academia of Fusion Dimension, destroying the city. Yūto, Shun, and Ruri then joined the newly formed Resistance to stand up against the Academia. During the battle, Yūto and Shun managed to defeat and interrogate one of Academia Duelist who revealed the existence of other dimensions and the Academia's goal to unite all of them. Shun attempted to turn him into a card, but Yūto stopped him as it won't change their situation, stating there has to be another way to bring back the peace of their world. Sometimes afterwards, Ruri was kidnapped by an Academia Duelist, Yūri, leading Yūto to look for her. While looking for her, he encountered Yūgo, a Duelist from Synchro Dimension who was also looking for his kidnapped friend, Rin. With Yūgo mistaking Yūto as Yūri and didn't answer to Yūto's question whether he was from the Academia or not, the two concluded that they are enemies and clashed, bringing out their respective ace monsters. However, both are interrupted by Shun and the other Resistance members, forcing Yūgo to retreat. Sometimes afterwards, Yūto heard that Shun was going to Standard Dimension to find the son of their enemy, Reiji Akaba, to make him a bargaining chip to free Ruri, so Yūto decided to follow Shun to Standard Dimension.

Duel Against Shingo Sawatari
While looking for Shun, he noticed Yuzu and mistook her for Ruri. Seeing her in trouble, Yūto took over her duel against Shingo Sawatari. Before taking the duel on, he said to Yuzu he doesn't want to see her getting hurt anymore. In the first turn, all he did was set Magic Cards. Later in the duel, he Xyz Summons his ace, "Dark Rebellion Xyz Dragon". He was inflicting real damage in the duel. After defeating Shingo, he took off his mask, where Yuzu and Shingo became confused and thought he was Yūya Sakaki. When Yuzu's bracelet shines, he disappeared without a trace. The confusion makes Shingo to complain Yūya was the culprit.

Pre-Maiami Championship
Still mistaking Yuzu for Ruri, Yūto watched over her from afar. When Yuzu goes back to the place Yūto was last seen by her and Shingo, and brought along Sora Shiun'in to learn Fusion Summon, this time, he was noticed by Sora who suddenly starts jumping and going around to catch him. Then, both Sora and Yūto fought using their Duel Disk. Sora correctly guessed that he wasn't from here, and Yūto responded back that it was also the same for Sora. He disappears again because of Yuzu's bracelet. He once again was seen observing Yuzu learning Fusion Summon with Sora and then remembered the time when he first met Yūgo. When Yuzu's bracelet shines for the third time, he is teleported to the place where Shun was. Reunited with his best friend, Yūto tried to convince Shun to stop his pursuit for Reiji, realizing that LDS has nothing to do with Academia regardless of Reiji's connection with Leo Akaba, but Shun wouldn't listen and still insisted on pursuing LDS Duelists. Shun attempted to attack Masumi Kōtsu after hearing she was from LDS. Yūto stopped him before he could Duel her, reminding that Standard Dimension wasn't their battlefield. Shun then noticed Yuzu and mistook her for Ruri, questioning her before Yūto knocked him out as he told him that she is not Ruri. He then told Yuzu that Fusion card doesn't suit him, offending Sora. Before they could argue further, Yūto and Shun got transported by Yuzu's bracelet due to Yūya's arrival.

Shun vs. Masumi, Yaiba, & Hokuto
While Shun was Duelling Masumi, Yaiba, and Hokuto, Yūto stopped Yuzu from interfering, not wanting her to get hurt. But this only angered Yuzu who pointed out his contradicting actions, asking was it alright for Masumi to get hurt and questioning his and Shun's identities. Yūto revealed that he and Shun are trying to save his captured comrade and Shun's younger sister, Ruri, who resembles Yuzu. He admitted that he at first mistook her as Ruri until he saw her happily learning Fusion Summon, something that Ruri would never do. Yuzu revealed that she learned Fusion Summon because she wants to protect her friends. Her motivation reminded Yūto of his own and commented that Yuzu's resolve of wanting to protect her friends by learning Fusion Summon is not wrong. Before leaving, he wished for Yuzu to survive if her involvement cannot be avoided even if it means using Fusion Summon and finally told her his name.

Duel Against Sora
Unlike Shun, Yūto did not take part in the Maiami Championship. He walked past a big screen displaying Shun's Duel against Sora as Shun talked about The Resistance. After Sora's defeat, he approached him in the hospital to interrogate him about Ruri's whereabouts, but he was only able to learn that captured Duelists were sealed inside cards and Ruri most likely also shared the same fate. Sora then insisted that Yūto take him to Shun for a rematch, but Yūto refused, telling Sora that he has already lost against Shun. When the guards discovered him, Yūto fled with Sora hot on his tail. At Central Park, Sora taunted Yūto about Ruri's fate, claiming that he would hunt down all Xyz users like Yūto, and suggested that destroying Fusion users would help get Ruri back. Yūto promptly challenged Sora as a result, and took damage on the first turn. Recovering, he brought out "Phantom Knights Break Sword", which Sora destroyed with his "Death-Toy Scissors Bear" and used to power it up. He brought out "Dark Rebellion Xyz Dragon" in the next turn and was in a position to win the Duel, but deliberately held back out of mercy, destroying "Scissor Bear", but leaving Sora with enough LP to stay in the match. Yūya arrived to help his friend as Yūto offered Sora the chance to surrender. When Sora didn't back down, and Yūto vowed to bring down Sora as the first step to bringing down Fusion, a furious Yūya joined the Duel, refusing to let Yūto hurt his friend further. Yūya quickly performed a Pendulum Summon, bringing out "Odd-Eyes Pendulum Dragon". When the Dragon appeared, both Yūto and Yūya felt a burning sensation in their chests as "Odd-Eyes" and "Dark Rebellion" roared at each other. Aiming to destroy both Dragons, Yūya attacked, but despite using "Timegazer Magician" to counter Yūto's Traps, Yūto was able to successfully protect "Dark Rebellion" with "Phantom Fog Blade" and "Booby Trap E". When Yūya pressed for answers to the enmity between the other two Duelists, Sora chided Yūto for not speaking since it'd reveal his faction's weakness. Sora proceeded to reveal his true strength, but before he could he was transported back to the Fusion Dimension by the Academia. Yūto proceeded to recover his Life Points and remove his Traps, pointing out to Yūya that their Duel was now pointless, and both Duelists mutually ended the Duel. Yūya pointed out how Yūto held back in the Duel, and reasoned that Yūto did not want to fight at all. Yūto spoke about how his hometown, Heartland, was once a city full of smiles, until the Fusion Dimension attacked, and told Yūya of the four known Dimensions. Yūya was skeptical, but declared that Duelling wasn't a tool for fighting, but for giving people happiness. Before they could finish their talk, however, Yūgo emerged from a beam of light on his D-Wheel, crashing into a surveillance camera. Upon removing his helmet, he was revealed to look like both Yūto and Yūya. Seeing Yūto, Yūgo challenged him to a Duel.

Rematch Against Yūgo
Yūto accepted Yūgo's challenge. During the course of the Duel, Yūgo remained upon his D-Wheel, thus Yūto had to run about to catch up to him and dodge the vehicle. Both Yūto and Yūgo vowed to defeat the other for taking something precious from them. Yūgo brought out his "Clear Wing Synchro Dragon", a clear hint for Yūto to bring out "Dark Rebellion Xyz Dragon" so the two dragons could duke it out. When the two Dragons were summoned, the eyes of both Duelists began glowing as both started claiming that they must destroy everything. Yūto negated "Dark Rebellion's" destruction using his Trap Card when "Clear Wing" activated its effect and increased its ATK. Yūto prepared to attack "Clear Wing", but Yūya managed to snap Yūto out of it by reminding him of how Duel wasn't supposed to be used to hurt people. While Yūto had the chance to defeat "Clear Wing", he ended his turn, remembering his vow to never hurt anyone. Yūgo, however, remained in his raging state and proceeded to defeat Yūto, who shielded Yūya from the shockwave. Upon losing the Duel, Yūto's soul was absorbed into Yūya, but not before entrusting his wish and his "Dark Rebellion Xyz Dragon" to Yūya. His Duel Disk and Deck were later retrieved by Nakajima.

Yūya vs. Isao Kachidoki
Yūya was Duelling against Isao during the second round of Maiami Championship. With Yūya cornered by Isao's violent Duelling that prevented him from getting Action Card and Idaten's monster effect that prevented him from attacking, Yūto's soul merged himself with Yūya's with Yūto temporarily took over Yūya's body, initiating the Awakening. He used Action Card Mad Hurricane to return his monsters on the field back to deck and used "Entermate Turn Toad" and "Entermate Cheermole" to Pendulum Summoned "Entermate Rakudown" and "Entermate Silver Claw". With the two have same levels, he constructed overlay network, summoning "Dark Rebellion Xyz Dragon" that swiftly defeated Isao.

Battle Royale
Obelisk Force appeared and turned Knight of Duels into cards, triggering Yūto's memories when Heartland was invaded, spilling it into Yūya as the result. This caused Yūto to once again initiated the Awakening and temporarily taking over Yūya's body. Obelisk Force immediately reduced his LP since their monster effect made him unable to activate any Magic, Trap, or Action Card. They then taunted him that he will share the same fate as Knight of Duels, angering him further. His soul and Yūya once again merged, creating two new cards: "Synthesis Magician" and "Antithesis Magician", which he used to perform Pendulum and then Xyz Summoned "Dark Rebellion Xyz Dragon." However, this didn't last long as an unknown darkness within Yūya slowly overwhelmed both Yūya and Yūto, causing it to take over Yūya's body and defeated the Obelisk Force using "The Supreme King Black Dragon - Odd-Eyes Rebellion Dragon."

Yūya vs. Reiji
After the end of the Battle Royale, Reiji, whom Yūya blamed for Yuzu's disappearance and his friends being turned into cards, challenged Yūya into a Duel with Heartland as their Duel Field. This brought back painful memories for Shun, who couldn't bring himself to tell what happened during the tragedy that befell his homeland. Reiji then started to reveal it instead, causing both Yūya and Yūto to shout at him to stop talking and start the Duel, which resulted with Yūya's lost.

Departure
The next day, the Lancers were prepared to go to the Synchro Dimension to recruit potential allies against the Academia by using their enhanced Duel Disk based from Reiji's research on Yūto's Duel Disk, leading Shun to accuse Yūya for stealing Yūto's Duel Disk along with his card as oppose to Yūya's earlier statement that Yūto entrusted it to him. In response to Shun's accusation, Yūto telepathically told Shun to trust Yūya, whom he has considered as his comrade that will never betray them.

Shun vs. Dennis
When Shun exposed Dennis' real identity as an Academia Duelist, Yūto reacted to the Duel within Yūya, watching the Duel intensely as his anger started to rise after hearing Dennis' part in Ruri's capture that also reminded him of his fallen comrades and his destroyed hometown. His anger spilled into Yūya and he asked does Yūya understand his feeling, to which Yūya answered that he understood, but disapproved to Duel that only filled by anger and hatred, and instead he will Duel to bring happiness for people like Yūto had asked him to.

Yūya vs. Crow
During Yūya's Duel against Crow, the mind-control chip that Roget placed inside Yūya's helmet forced Yūya to enter his state of rage and synchronised his mind with his dimensional counterparts who were in the vicinity, including Yūto who was inside him and they together Duel against Crow in the same state of rage as Yūya. After much struggle, Crow was able to destroy the chip inside Yūya's helmet, freeing Yūya from his Awakened state, which also freed Yūto, Yūri, and Yūgo, at the cost of his defeat. Once the synchronisation ended, Yūto fell unconscious.

Yūya vs. Barrett
When Yūgo and Yūri summoned "Clear Wing Synchro Dragon" and "Starve Venom Fusion Dragon" during their Duel while Yūya had "Odd-Eyes Pendulum Dragon" and "Dark Rebellion Xyz Dragon" on the field during his and Barrett's Duel, the Four Heavenly Dragons started to resonate with each other causing Yūto and dimensional counterparts to go to the state of rage again. This caused a dimensional hole to appear in the sky as they stated that they have been waiting for the moment they will become one and attempted to reach the dimensional hole. However, this was interrupted by Yuzu's arrival that automatically transported Yūgo and Yūri away, ending the synchronization.

Gongenzaka & Shingo vs. Kaito
Yūto mentally communicated with Yūya, explaining to the latter that Kaito used to be a professional Duelist from Clover Branch of Heartland Duel School, a rival branch to Spade Branch where he and Shun attended prior the invasion. However, he noticed that Kaito has changed since his Dueling used to be subtle yet dynamic, but now he could only sensed anger in his Dueling, making Yūto wondering what had happened to Kaito while he was away. After Kaito defeated Gongenzaka and Shingo, he challenged Yūya to Duel him, intending to card him along with Gongenzaka and Shingo. Hearing this, Yūya decided to accept, not wanting anyone to be carded again. Yūto told Yūya it'll be pointless to Duel him because the current Kaito won't listen to anything he says. In respond, Yūya determined to convey his words and feelings to Kaito through Duel instead like he did with Jack.

Yūya vs. Kaito Tenjō
Yūto tried to persuade Yūya once more, explaining that while he was able to communicate with Jack because both of them shared the same goal to bring happiness to the City, the same thing won't be possible with Kaito whose heart was filled with rage. This didn't change Yūya's mind who reminded Yūto of his own wish to bring smile to people, asking him to trust him. Reluctantly, Yūto let Yūya Duel. Soon, Kaito overpowered Yūya, already seeing through his tactic after his previous Duel against Shingo and Gongenzaka, making Yūto realised that Kaito's skill has much more sharpened than before. He again tried to persuade Yūya to stop, but the latter still insisted to continue. Unfortunately, even after summoning "Odd-Eyes Rebellion Dragon", Kaito still able to counter it with his reverse card to summon another "Galaxy-Eyes Cipher Dragon", destroying the Supreme King Black Dragon and left Yūya's field wide open. Finally deciding to help, Yūto quickly instructed Yūya to use the dragon's monster and Pendulum effects. Understanding that he was still not strong enough but still wanting to open up Kaito's heart regardless of his and Yūya's current strength, Yūto finally came up with this tactic: Duelling together with Yūya, both of them Xyz summoned "Dark Rebellion Xyz Dragon", shocking Kaito. By summoning his ace monster, Yūto tried to remind Kaito of him during their days at Heartland Duel School. Yūto's strong presence within Yūya allowed Kaito to momentarily see his splitting image, causing Kaito to thought Yūya as Yūto. Before the Duel could continue, Shun arrived with Sayaka Sasayama and Allen Kozuki to clear the misunderstanding. Despite Shun's assurance that Yūya and the others are allies, Kaito remained defiant and left the scene, leaving Yūto and Yūya in wonder.

Resistance Hideout
At the Resistance hideout, both Yūya and Yūto were lamenting over their inability to open Kaito's heart, only feeling Kaito's anger throughout their Duel even after they have summoned "Dark Rebellion". Allen then commented Yūya's resemblance with Yūto, even starting to think that Yūya might actually Yūto himself by the fact that he used "Dark Rebellion" until Shun cleared the confusion. Allen questioned Yūto's whereabout since he was supposed to be following Shun to Standard Dimension but was now absent. Before Yūya could answer, Yūto told him not to reveal that he is inside him because they won't understand their condition, something that Yūya reluctantly agreed. They were saved from the question by Shun who explained that Yūto had suddenly vanished and then entrusted "Dark Rebellion" to Yūya, whom at first Shun suspected for stealing the card. However, after watching Yūya throughout their battle at Synchro Dimension, he came to believe that Yūto had indeed entrusted his ace monster to Yūya and understood why he did so, something that relieved both Yūto and Yūya. Their relief was cut short when Allen and Sayaka revealed that while they were gone, Academia had launched a massive offensive attack that destroyed most Spade and Clover branches' Resistance Duelists and residents, including Kaito's whole family, which shocked Yūto.

Duel Against Edo Phoenix
While looking for his father, Yūya asked Yūto whether he had met his father before, but Yūto denied this and revealed that the words he said about Duel is to bring happiness to people's future was derived from Ruri's words, something that Yūto asserted Ruri had heard from Sayaka which Yūshō had taught to the latter. Yūya then switched the conversation to he  could now freely communicate with Yūto compared to previous instances, and wondered was it because they are at Xyz Dimension. Yūto deduced that it was most likely because of what happened during the Duel against Barrett when the four dragons resonated, acknowledging the existence of an unknown being that taking over them. Yūto theorized that their current condition has something to do with it and he felt his current residence in Yūya's body was all according to "Dark Rebellion's" intention.

They were interrupted by a hooded young man who questioned Yūya's presence and his father's name, mistaking him as a lost child. When Yūya revealed that his father is Yūshō Sakaki, the man revealed himself as an Academia Duelist, Edo Phoenix, and attacked Yūya. While Yūya tried to communicate with Edo in hope of finding out about his father, Yūto tried to dissuade Yūya from doing so and instead concentrate on winning the Duel because Edo was from Academia, but Yūya insisted on trying to speak with him because he probably won't get another chance to find some clues about his father. Unable to dissuade Yūya, Yūto pointed out the fact that Edo hates Yūshō, which means even Yūshō couldn't make him smile. Yūto further admitted that when he returned to Heartland and saw its desolated scenery, he was having a second thought about the ideal to bring smile with Duel. While it was certainly ideal, he is now convinced that ideal can be achieved only after Academia has been defeated.

With this in mind, Yūto forcefully possessed Yūya's body and took over the Duel, summoning "Dark Rebellion" to reduce Edo's LP to 100 before letting Yūya take control once more. The switch didn't last long, however, as Yūto soon was overcame by his anger for Edo who he was sure had defeated his Resistance comrades and regret for ever going to Standard Dimension instead of staying and protecting his comrades and Kaito's family. Yūto forcefully switched place with Yūya again and summoned "Dark Requiem Xyz Dragon", turning the tide. However, just when it was seemed he was about to win, Edo activated his monster's effect to give 1000 damage to both of them, forcing the Duel to end with a draw. The shockwave from the effect sent him and Yūya to crash and buried in rubble as they heard Academia Duelists arrived to help Edo and learned of Edo's identity as Commander-in-Chief of Academia.

Shun vs. Kaito
After Dueling with Edo, Yūto and Yūya returned and saw smoke nearby the Resistance hideout and headed there, thinking it was Academia, only to find Shun and Kaito Dueling. Yūya tried to stop the Duel, but neither Kaito nor Shun were willing to back down, so Yūto told Yūya to let Shun handle the situation. As he was watching the Duel, Yūto was surprised that for the first time Shun was trying to convey his words through Duel. He then unconsciously took over Yūya's body as he reminisced their times as students when Shun and Kaito were admired by children and how they looked up to the two of them. Consequently, this also gave away Yūto's existence inside Yūya to Shun and the others. Shun, however, weren't so surprised by the revelation as he already has a feeling that Yūto was nearby, making Yūto smiled at him.

Duel Against Tyler Sisters
While searching for Sayaka who suddenly went out to look for Kaito, Yūya and Shun heard Shingo's scream and then found him, Gongenzaka, Sayaka, and Allen injured after they were defeated by Academia Tag Duelists, the Tyler Sisters, Gloria and Grace. Hearing the insult from Tyler Sisters, Yūto possessed Yūya's body for a moment and shouted at the sisters that he and Shun didn't run away but had another thing to do on their own and if they were there, they could've prevented the sisters from carding many of their allies. Yūya questioned did Yūto knew them, which Yūto denied but he had heard of them as Tag Duelists who uses Amazoness Deck that nearly wiped the Spade Branch. Controlled by his rage, Yūto urged Yūya to accept their Tag Duel challenge together with Shun. As the Duel went on, Yūto increasingly became angered by the sisters' taunt and insults despite Yūya's warning not to. At Yūya's second turn, Yūya finally told Yūto to calm down, reminding him that if he let his anger controlling him further, they will be possessed by the mysterious being and he didn't want to experience that again. Hearing Yūya's plea to trust him and promise he will answer his and Shun's feelings, Yūto decided to leave the rest to Yūya. Yūya summoned "Dark Rebellion Xyz Dragon" that increased the sisters' LP to 10100, making Yūto questioning Yūya's plan to wipe out the sisters' LP. Yūya then activated "Miracle Rocket Show" and "Smile World" to negate battle damage to the sisters and increased each of their monster's ATK by 400 before instructing Shun to activate "Raid Raptors - Rise Falcon's" effect to increase its own ATK. Now understanding what Yūya was planning, both Yūto and Yūya activated "Dark Rebellion's" effect to increase its ATK and attack Grace's "Amazoness Pet Liger". Using "Miracle Rocket Show's" final effect, they able to inflict 10,225 damage to the sisters, defeating them.

Duel Against Obelisk Force
While on their way back to hideout, they were intercepted by the Obelisk Force who challenged them to Duel. Since Allen, Sayaka, Shingo, and Gongnenzaka were still injured from the previous Tag Duel, Yūya and Shun Duel the Obelisk Force by themselves. After witnessing the impact Yūya did to the Tyler Sisters, Yūto decided not to interfere this time and watch over the Duel, trusting Yūya that he will able to converse properly even if the opponents are the Obelisk Force with his current strength, something that Yūya was grateful of. As the Duel went on, however, when the Obelisk Force summoned "Antique Gear Chaos Giant", Sayaka ran away in fear due to the trauma of the first attack and almost hit by a falling debris, prompting Shun to rush over to protect her, shocking Yūto and the others. While Sayaka was saved, Shun was wounded and collapsed, leaving only Yūya to fend off against the Obelisk Force. They fortunately were saved by Kaito's arrival who assisted in defeating the Obelisk Force. While tending to Shun, Edo and his Academia squad arrived, challenging them.

Yūya vs. Edo
Edo forcefully dragged Yūya to Duel him and trapped him inside his magic field so no one can interfere their Duel. Yūya refused to Duel out of concern for Shun, but Yūto revealed to Yūya from his experience that Academia Duelists are ruthless people who will attack unarmed, injured, and even people who are on the verge of death, which means the only way to save Shun was to defeat Edo. After Kaito convinced Yūya he will take care of the Academia squad, Yūya accepted Edo's challenge. During the Duel, Yūya contemplated a way to speak with Edo, a thought that surprised Yūto who once again told Yūya to cease the thought because Edo will never listen to him, though this didn't stop Yūya to keep trying. Yūya was momentarily distracted when seeing Kaito got surrounded by the Academia squad until Yūto told him to focus on his own Duel. Edo then revealed what happened between him and Yūshō and how he persisted with his loyalty to Academia's Dueling. Hearing this, Yūto again told Yūya that it was impossible to speak with Edo since he only believed that Academia's Dueling is the most righteous. To his confusion, however, Yūya suddenly smiled after hearing Edo's story, and Yūto questioned this, to which Yūya answered he was just thinking of the fact that Edo has been keeping the half of the torn "Smile World" for the whole time. On the verge of defeat, Yūto suggested that Yūya could counterattack by using multiple monsters to attack since Edo's "Destiny HERO - Dystopiaguy" could only use its effect once per turn. While Yūya agreed it was a good plan, Yūya still stayed true to his determination to Duel with the way he believes in. Yūto reminded Yūya that his father wasn't able to open Edo's heart, but Yūya was sure that his father had succeeded in opening Edo's heart, but Edo just refused to admit it, so he determined to make Edo remember the joy he felt during his Duel against his father. As Yūya pointed out this fact to Edo, the latter further revealed how Yūshō said he was willing to forgive Academia if they can change their way and smile together with him, believing that forgiving each other is the only way to end conflict, a way that Yūto never thought before. Yūto continued to observe the Duel, shocked at how strong Yūya's determination was even after being beaten so badly. Once Yūya defeated Edo, they were surrounded by the Academia soldiers that Noro had called in case Edo lost. Just as Noro ordered them to attack, to everyone, including Yūto's shock, Edo defended Yūya as he he declared his treachery against the Professor, which followed by the Tyler Sisters. Knowing that Edo and Tyler Sisters' feelings are genuine, Yūto sincerely asked them through Yūya to help him bring back the smiles and happiness to Xyz Dimension, which Edo agreed. Kaito and the Resistance then arrived, forcing Noro to surrender, and Edo's speech convinced the remaining soldiers to defect as well.

Departing to Fusion Dimension
Back at Resistance hideout, while discussing their decision to let Edo and the Academia in Heartland to help them, Yūto momentarily possessed Yūya's body and spoke to Kaito and the others of what Yūya said during his Duel against Edo: only retaliating when being attacked won't bring the conflict to the end, something that Yūshō also believed. He added while he knew that there are things that couldn't be forgiven, but by having a courage to forgive others they can open the path to the future. Yūto assured Kaito that he just showed them that courage by admitting his wrong doing and willingness to forgive the Academia while enduring the pain of losing his family and friends. Edo then informed that there's a way to change back the people who have been carded, but first they need to retrieve all the carded people at Academia in Fusion Dimension. Using the dimensional transfer device in Academia's base in Heartland, Yūto, Yūya, Kaito, Gongenzaka, and Shingo went to Fusion Dimension.

Yūya vs. Isao
Once arriving in Fusion Dimension, Yūto and the others reunited with Yuzu who were cornered by Dennis and his squad. Yūya was then pinned and forced to accept challenge against Isao, the Duelist Yūya had defeated before during Maiami Championship. When Yūya accepted, Yūto questioned his decision, to which Yūya answered that Isao's current state was his fault. Yūto noted Isao's strong grudge against Yūya and "Dark Rebellion", and the latter deduced that the cause was because he defeated Isao using it while being possessed by the unknown darkness. Yūya has difficulty avoiding Isao's attacks when trying to get Action Card, but eventually able to evade by using the roller skates given by Allen, though he at first has difficulty balancing himself and barely defended his monsters from destruction. Yūto asked did Yūya do it on purpose, which Yūya denied. After much struggle, Yūya finally able to defeat Isao using his Trap card "Acrobat Tower" and earned Isao's acceptance. Seeing this, Yūto jokingly commented that Yūya was such a stubborn reckless Entertainment Duelist that contagious to others.

Reunited with Lancers
During Yūya's Duel against Captain Solo, the remaining Lancers along with Crow as their new member, saved Yūya and helped him defeat Solo and his crew. On their way to Academia, Yūya and the others briefed of what they have known so far. When Yūya mentioned about Yuzu, Serena, and Ruri being captured, Gongenzaka stated there were three girls with same face captured by Leo, but Yūya reminded there's also Rin whom Yūgo was looking for. Yūto confirmed this and stated his understanding that Yūgo must have mistook him as Yūri during their first encounter. Yūto was surprised when Reiji revealed that he, Yūya and two others who resembles them might be involved in the Professor's plan called Revival Zero.

Survival Duel
During Yūya's Duel with Battle Beast, Sanders revealed that the Professor had ordered him to eliminate Yūya specifically. This caused Yūya to become distracted, and Yūto and Yūya conversed about the Professor's attempts on them specifically, their link to each other, Yūgo and Yūri, and Yūto's soul residing in Yūya. Yūya explained that when couldn't think of a answer, he thought of Leo Akaba. Yūto agreed that Leo might know the reason for their fusion. Yūya recalled that terrible things happened after they became one, Yūto mentioned he was consumed by hatred when he noticed the other Duelist. Yūto explained to Yūya that when the Four Dimension Dragons came together, he heard a raging voice from the depths of his heart. Yūto believed that Leo knew the true identity of this voice.undefined After Yūya defeated Battle Beast and Sanders, he told him it was time for them to go to know what they really are.undefined

Duel Against Ruri & Serena
Yūto and Yūya arrived in a room resembling a laboratory where they met Ruri, much to Yūto's relief and happiness. Hearing that Shun also came and was injured, they made their way to where Shun is, but Ruri suddenly challenged Yūya to a Duel. Assuming that Ruri was also controlled like Serena, Yūya and Yūto accepted her challenge to save her. When Yūya started his turn, Yūya noticed the cards in his hand were Yūto's cards. Yūya concluded that Yūto's strong feeling to save Ruri made the card appear inside his deck. Yūto and Yūya started their turn by setting three cards and then ended the turn as Yūto borrowed Yūya's body to try reminding Ruri of her real self, but Ruri continued her turn while she dismissing Yūto's claim who was inside Yūya's body. Yūto and Yūya were shocked when Ruri performed Fusion summon, decreasing their LP to 2,500. Noticing "Parasite Fusioner" attached to Ruri's "Lyrical Luscinia - Independent Nightingale", Yūto concluded that Ruri was controlled by the parasite monster, which Yūya agreed. Shun then arrived, surprising Yūto and Yūya. Shun revealed that he had Dueled Ruri and freed her from her mind control, but it seemed in order for her to be completely freed, they must defeat the Duelist who is controlling her. Yūto and Yūya able to hold themselves again Ruri and slowly gain the upper hand using Yūto's new "Phantom Knights" monster until Serena arrived, knocking out Shun with a taser as she joined the Duel. Serena then revealed to Yūya that Yuzu has also under the Doctor's control, enraging Yūya. Seeing Yūya began to lose to his anger, Yūto calmed him down as he told him that now they were sharing the same feeling of hatred and unable to forgive the Doctor who had controlled Ruri and Yuzu. Yūto then fully switched his body and mind with Yūya, allowing him to take control of the Duel, summoning his ace monster "Dark Rebellion Xyz Dragon" as both he and Yūya swore to return Ruri, Yuzu, and Serena from the Doctor's control. Yūto was warned by Yūya that they were planning something and he knew so he started his plan. He used "Single Distraction" to destroy "Queen" but Serena used the effect of "Parasite Fusioner" to negate the destruction. He learned "Parasite Fusioner's" effect and that the damage will be higher from Yūya. He then attacked "Queen" but Serena equipped "Parasite Fusioner" to "Dark Rebellion", weakening it. He told Yūya the plan backfired and used "Phantom Knights Around Burn" to destroy all cards on the field by banishing two Phantom Knights cards in his graveyard. He then sent "Parasite Fusioner" to the graveyard to prevent "Dark Rebellion's" destruction and used the second effect of "Around Burn" to deal damage to Serena and Ruri for every monster sent to the graveyard during the battle phase. When "Dark Rebellion" was weakened again, Yūto used "Evasion" to dodge "Queen's" attack and "Miracle" to halve damage but lost control over Yūya's body when hit by the attack. He asked Yūya was he alright and met the Doctor through a monitor. Yūya's anger after seeing Yuzu being controlled as well caused both him and Yūya to awakened, summoning a new Xyz-Pendulum monster, "Odd-Eyes Raging Dragon" that easily defeated both Ruri and Serena. They quickly checked on Serena and Ruri, but both quickly ran away the moment they regained their consciousness.undefined

The Origin of Four Dimensions
When they found the Doctor with the girls, they were trapped inside a cage set by the Doctor and could only watch them leave. He and Yūya then saw from the monitor that the Professor was telling Yūshō, Reiji, and Reira about his past that involved a Duelist named Zarc that once almost destroyed the whole world with his four dragons that now in the possession of Yūto and his counterparts. They then noticed their cards shining from their extra deck. Before Yūya could look at them, they entered a synchronized awakening when Yūgo and Yūri summoned "Clear Wing Synchro Dragon" and "Starve Venom Fusion Dragon" respectively elsewhere, unleashing a strong gust of wind that blew away Kaito and Edo who came to save them as he and Yūya stated they will become one.undefined When Yūya went to the Professor's inner chambers, Yūto saw Ruri and her counterparts being brought to the room in a tube and the Doctor arrived as well. As he promised to rescue Ruri, he listened to the continuation of Leo's story and learned how Leo created four cards that could defeat Supreme King Dragon Zarc but were stolen by his daughter, Ray, who then used it to defeat Zarc, which caused the dimension to be split into four. He was furthered shock when Leo revealed that not only Ruri and the other girls were the reincarnations of Ray, but he and his counterparts were the reincarnations of Zarc.undefined

Yūya and Reiji vs. Leo
Hearing Leo's plan to revive Ray and recreate the original dimension, ARC-V, by fusing the girls and Four Dimensions back into one by accumulating the life energies of the people who were carded, Yūto and Yūya determined to stop Leo, challenging him to a Duel together with Reiji. Now knowing the true identity of the darkness inside them, Yūto told Yūya that they can stop him from taking over them like before and quickly rescue Ruri and the others by stopping the machine. Leo still believed that Zarc would revive due to the fact that Yūto was already being absorbed, but Yūya told him that even if Yūto is inside of him, they still want to bring smiles to everyone, overcome the evil in them, and protect the four girls. Yūto added about how Ruri's words are what has been supporting him all this time, much to Ruri's relief. Unfortunately, when the machine that was trapping Ruri and the others started to activate, Yūto and Yūya became enraged as they were hearing Yuzu and Ruri's cries for help, causing them to awaken.undefined Yūto and Yūya tried their best to hold off Zarc, Yūto insisting that they could still control themselves, which Yūya agreed, and the two continue the Duel. As the Duel went on, Yūto and Yūya started to succumb to Zarc's control. When Reiji tried to get Yūya to snap of it, Yūto was able to make brief contact with him, pleading to him to stop them before Zarc once again took control. He and Yūya then returned to their Awakened state and bringing out "Odd-Eyes Raging Dragon" whose effect was enough to finish defeat Leo. Before they could declare direct attack, they returned to their senses when the girls stated their belief in them, but they continued their attack when Yūto heard Ruri's scream as her body began to disappear. Before they could defeat Leo, Yūshō interfered, using a prototype card that bound Yūya and Yūto and forcefully ended the Duel.undefined

Yūri vs. Yūshō
After returning to his normal self thanks to Yūshō's duelling, Yūto got worried as Yūshō seemingly got cornered by Yūri. Yūya assured him not to worry because his father was in a situation like this before and explained the time when he first saw his Duel. However, he and Yūya started to get jolts of pain after Yūri Fusion Summoned "Starve Venom" and Synchro Summoned "Clear Wing" as the two dragons were resonating with fragments of Zarc's souls inside them. When the resonation started to become too much for Yūya to endure, Yūto was started to be consumed by Zarc and yelled at it to stay away.undefined

Yūri vs. Yūya
After witnessing Yūshō's defeat at Yūri's hand, Yūya and Yūto nearly lost themselves to Zarc's control until Yūya drew "Smile World" that reminded him of Yūshō's words, allowing them to calm down while enduring Zarc's influence, determined not to let Zarc come out. Duelling while resisting Zarc's control proved to be difficult because the moment "Odd-Eyes", "Starve Venom", and "Clear Wing" were summoned, Zarc's power also grew stronger inside them. To counter against Yūri's vicious combo that he used against Yūshō, they decided to use permanent trap card "Starlight Force" to negate all of the effects of monsters that Yūri summoned from Extra Deck and lowered its level to 4, preventing Yūri from using his vicious combo. Knowing it wasn't enough, they knew they need to summon "Dark Rebellion" to win. When Yūya hesitated to summon "Dark Rebellion" out of fear they won't be able to resist Zarc's power if the four dragons are present, Yūto expressed his faith in Yūya that even though he himself would be swallowed by darkness, he believed that Yūya can endure it and save him since Yūshō was watching over him. This convinced Yūya to summon "Dark Rebellion". Before he was completely swallowed by the darkness, Yūto told Yūya not to worry about him and to hurry up using "Dark Rebellion". Unfortunately for them, Yūri used his trap card to take control of "Dark Rebellion", cornering Yūya. Yūto, who has fallen completely into Zarc's influence, now only thought of becoming one with his counterparts.undefined Together with Yūri and Yūgo, Yūto continued to urge Yūya to become one with them as the latter continued to struggling. The encouragement from his friends strengthened Yūya's resolve to win against Yūri, retrieving "Dark Rebellion" and take control "Clear Wing" using his newly summoned "Entermate Trap Mimic", which in the process also freed Yūto and Yūgo's soul from Zarc's control and supported Yūya. Unfortunately, this didn't last long as Yūya's decision to focus only to win has allowed Zarc to fully take control of their souls right after Yūya defeated Yūri. Yūto and his counterparts became one, reviving Supreme King Dragon Zarc.undefined

Ray & Reira vs. Zarc
When Reira Dueled against Zarc together with Ray inside his body, they successfully destroyed the "Supreme King Dragon Zarc" and the Supreme King Servant Dragons that greatly weakening Zarc. Yuzu and Yūya's friends' call awakened Yūya's soul inside Zarc, which also included Yūto, Yūgo, and Yūri. With Yūto and the others' help, Yūya fought back against Zarc's control and managed to drew "Smile Universe" that summoned back the Supreme King Dragon and "Odd-Eyes" with their effects negated and then gave the total of their ATKs to Reira and Ray, allowing them to defeat Zarc for good.undefined

Yūya vs. Shun
Following Zarc's defeat, Yūya went to Fusion Dimension under Reiji's instruction to Duel Shun in preparation to expel Zarc's soul who was sealed inside Reira. In Academia, Yūya learned from Leo that Yūto, along with Yūgo and Yūri, were not revived like he did after Zarc was defeated and Leo couldn't find any trace of their existence inside Yūya, so he assumed that the three of them have gone, a revelation that greatly upset Shun. However, Shun briefly sensed Yūto's presence near the end of his Duel against Yūya that he believed as a sign that Yūto was still living inside Yūya, which gave Shun hope that Ruri may still be alive as well.undefined

Yūya vs. Jack
Noticing that Yūya was afraid to summon the four dragons since it may awaken Zarc's soul inside Reira, Jack challenged Yūya to a Duel. Yūya tried his best to find a way to win without summoning the dragons, but this led him into corner. From within Yūya, Yūto questioned was he fine losing like this. Yūgo, and Yūri also voiced their disagreement, Yūto saying that his "Dark Rebellion Xyz Dragon" didn't want to lose and telling Yūya to listen to the dragons' voices. They told Yūya that they should be able to do so, which helped Yūya realized that even though Zarc's evil heart has left from them, it still doesn't change the fact that they were Zarc who could connect his heart with monsters, a feat that he should be able to do as well. With their support, Yūya finally summoned the four dragons.

Powers and Abilities
Yūto's Duel Disk has a system similar to Action Field, enabling him to inflict real damage, destruction, and pain in a Duel even without the presence of an Action Field. Examples of this are wind being felt from  Solid Vision  holograms, causing explosions that can shake an entire building, and using " Phantom Death Spear " to pin  Shingo  to a wall by his coat. Upon his next appearance, he was also shown to be acrobatic, performing several high and agile jumps in a scuffle with  Sora. He can also dash to the point of being nearly a blur that a pair of guards couldn't react fast enough. Yūto is stronger than he looks; he was able to effortlessly knock down  Kakimoto  off-screen, and knock  Shun  unconscious with a single punch to the gut.
 * Arc V Yuto berserk.pngThe Awakening - Like his dimensional counterparts, Yūto has the ability to enter the Awakened state that increases his Duelling skill, but came at the cost being blinded by his rage, resulting Yūto has no other objective but to defeat his opponent in brutal way. However, this got worsened after Yūto witnessed the Obelisk Force turning people into cards that triggered his painful memories of the tragedy that befell his homeland. Yūto's sadness and hatred gave birth to a darkness that was strong enough to overwhelm both him and Yūya, causing their Duelling skill increased, but slowly losing their humanities. During the state, Yūto has no recollection of what happened.


 * Yuto-Yuya 104-4.pngPossession - After he was absorbed into Yūya, Yūto is able to take over Yūya's body whenever he sees fit whether it's with or without Yūya's permission. Initially, Yūto was only able to possess Yūya whenever triggering the Awakening, but ever since their arrival at Xyz Dimension and able to communicate with each other, Yūto was able to freely take over Yūya's body without triggering the Awakening. When he possessed Yūya's body, Yūya's eyes momentarily glowed purple before it turned into Yūto's grey colour. However, while Yūto wasn't Dueling, Yūya's eyes remains red. Yūto's possession, especially when he was angered, is so strong that even Yūya himself unable to prevent it nor taking back control of his own body. During his Duel against Ruri and Serena, Yūto is able to fully switch his body and mind with Yūya, not merely possessing Yūya's body.


 * Yugo Yuto Yuri 881.jpgSynchronization - Like his dimensional counterparts, Yūto is able to synchronised his mind with his dimensional counterparts. This was first triggered during his rematch against Yūgo. The synchronisation was triggered because "Dark Rebellion Xyz Dragon" and "Clear Wing Synchro Dragon" were calling one another, resulting both Yūto and Yūgo to awaken at the same time.


 * Telepathy -  Yūto is also capable of selectively communicate telepathically with other people from within Yūya that can only be heard by the person whom he is communicating with, even without Yūya himself realizing.
 * Communication with Duel Monsters  - Being one of Zarc's reincarnation, Yūto inherited Zarc's ability to hear the voices of Duel Monsters and communicate with them, particularly with his ace monster, "Dark Rebellion Xyz Dragon" and the other three dragons.

Deck
Yūto runs a "Phantom Knights" Deck that focuses on Xyz Summoning. He uses several copies of "Phantom Knights Shadow Veil" to protect himself against attacks and to Xyz Summon his ace card, "Dark Rebellion Xyz Dragon", while using cards like "Phantom Death Spear" and "Phantom Wing" to protect it as well as damage the opponent, enabling a OTK through the effect of "Xyz Dragon". His monsters are Level 3 and "Dark Rebellion" is Rank 4, so Yūto takes advantage of the effect of his "Phantom Knights Break Sword" in the early game. Should it be destroyed, its other effect instantly sets up the Summon of "Dark Rebellion".

His Dueling style reflects his merciful nature and refusal to hurt others. He uses many protective cards and cards that restrain the opponent, additionally he often leaves the opponent with enough life to survive his assaults and offers them the chance to surrender peacefully, only finishing them off should there be no other choice.

His deck also feature many Trap cards that can be used in place of a Monster card, allowing him to gather many Xyz Material easily. And like Shun and Kaito, features an irregular "Rank-Up-Magic".

Trivia

 * Yūto's voice actor Manpei Takagi and Yūgo's seiyuu Shinpei Takagi are twin brothers.
 * Yūto's and Yūgo's flashback in episode 18 was initially scheduled to appear in first episode.
 * Based on the sixth ending theme, it's strongly implied that Yūto hides his feelings and relationship with Ruri from Shun since he is shown trying to hide himself from Shun when the latter passed by while he is alone with her.
