Yūya Sakaki

"Swing! Pendulum of the Souls! Draw your arc of light on the skies! Pendulum Summon!"

- Yūya says this whenever he Pendulum Summons.

Yūya Sakaki ( Sakaki Yūya) is the main protagonist of the Yu-Gi-Oh! ARC-V anime. He is a born-entertainer who attends the You Show Duel School to advance his Dueling expertise and become an "Entertainment Duelist", a specific type of professional Duelist, similar to his father. He has three known dimensional counterparts: Yūto (from the Xyz Dimension), Yūgo (from the Synchro Dimension), and Yūri (from the Fusion Dimension). He is one of the Lancers.

Appearance
Yūya appears as an average height boy for his age. He has hair that is maroon, following with green on top of it. He wears dark-ish yellow goggles that a blue star on the right-eyed lens and wears it on his head that he uses to cover his eyes when he's sad or about to get tears in his eyes. His eyes are crimson. He wears a neck belt. He has a blue pendant around his neck. He wears a jacket which is his Maiami Second Junior High School uniform, that he wears it as a cape. He wears pants of his choice that are green with two pockets on both right and left sides. He also wears a brown belt. He wears pink shoes. He wears red wristbands, one on each wrist. His skin color bright and normal. Yūya and his dimensional counterparts shares striking resemblance.

Personality
Yūya is a fun-loving and energetic boy. He is very theatrical and loves to entertain people, traits he seems to inherited from his father, Yusho Sakaki. He idolized and loved his father very much and wishes to become an entertainer like him one day. After his father disappeared during an important match, Yuya was left heartbroken and traumatized by the event because his beloved father was labeled as a "coward". To cope with his father's disappearance and beat people to insulting him about his father, Yuya acts like a fool, leading his friends and other people are often baffled by Yuya's behavior and believes he doesn't take things seriously. Because his father was so famous, his friends and other people seems to have high expectations of Yuya to live up to his father's reputation while simultaneously quick to bring up Yusho's "cowardice" or scold him for his clownish actions. Only after Yuya defeated Strong Ishijima he finally dropped his foolish acts.

Yuya has shown to have a good deal less self confidence. As such, when he finds himself cornered or something happens that breaks his confidence, he tends to pull his goggles down so nobody can see his eyes. At times like these, he ends up recalling lessons from his father, or relies on support from his friends or mother to regain his confidence and continue the Duel.

Initially, Yuya was more emotionally vulnerable regarding Pendulum Summoning, believing it to be a power granted only to him. When both Reiji and Shingo Pendulum Summoned, he was speechless, but coaching from Shuzo and the lessons he learned during his Qualification Duels have turned him into a Duelist that enjoys the challenge set before him, and he smiled as he was cornered by Shingo when he Pendulum Summoned in their rematch.

Yuya believes that Dueling is for the purpose of making people happy, and he is disgusted when it is used for hurting people and much worse, for war. However, confrontations with his dimensional counterparts and learning about the four dimensions as well as the crisis between them start making him doubt his ability to entertain people with Dueling. His Duel against Isao further hurt his optimism after using Berserk Mode and winning brutally using Yuto's card.

As Yuya becomes more involved in the Interdimensional Domination, added with repeated incidents of triggering Berserk Mode, Yuya progressively finds it more difficult to entertain with dueling, and stops using his usual phrases like "Ladies and gentlemen!". He is also become more vulnerable to emotional breakdown and even hostile and impatient, such as when Reiji revealed that the Battle Royale was a test to recruit Lancers which led to many of his friends becoming sealed in cards. This made Yuya without himself realising started to slowly losing his track of his way of Duelling, focusing on becoming stronger to defeat his enemies rather than for the sake of bringing happiness to people despite staying true to his belief. Only after his Duel with his mother Yuya finally regain his spirit.

When in Berserk Mode, Yuya is collected and cold, speaking no more than necessary. However, when witnessing Yuto's memories of the Academy's attack on the Xyz Dimension and seeing the Knight of Duelsbeing turned into cards by the Obelisk Force in front of him, Yuto's hatred towards the Fusion Dimension spills into Yuya, turning him even more aggressive and ruthless. This is worsened when the darkness inside him consumed him, making him desire to harm his enemies to the point he enjoys it.

Etymology
The syllable "Yū" in this character's name comes from the "Yū" in the Rōmaji of "Yu-Gi-Oh!" ( Yūgiō, lit. King of Game) and past 4 main characters' first or last names of the series (Note: There are other ways to write "Yūya" in Japanese). Sakaki (榊), also known as Cleyera japonica, means "Divine Tree" in Japanese.

Yuya's name may also derived from Yuya, a powerful Egyptian courtier during the eighteenth dynasty of Ancient Egypt, father of Tiye, the Great Royal Wife of Amenhotep III. When the latter died, his son ruled the Ancient Egypt as Amenhotep IV, but later changed his royal name for Akhenaten, whose namesake may have inspired Akhenaden, the father of Priest Seto and uncle of Atem.

History
In his childhood, Yuya sat by himself crying when his father, Yusho Sakaki came in to cheer him up. He gave him advice on laughing whenever he felt down and used Yuya's pendant to explain that if Yuya was happy, the happiness would swing back at him. At another unknown point in his childhood, he lost his Pendant in a park, and cried when he was unable to find it. His father learned of the incident and reaffirmed the statement that Yuya should look up and laugh whenever he felt like crying. Yuya did so, locating his Pendant hanging from a tree branch. At one point, Yuya said that he wanted to be a Duelist just like his father when he grew up, and his father said Yuya's got it a bit wrong. He said instead of being like him, Yuya should always be himself. At a later point, Yuya and his mother, Yoko Sakaki, watched the final Duel between Yusho and Strong Ishijima. When Yusho did not show up, Yuya ran to the bottom of the stands, saying that his father would appear, and challenged Ishijima to a Duel until his father arrived. Yoko pulled Yuya from the stands as he continued to protest. As the resulted, he was bullied for these remarks, constantly being called as "a son of a coward", even being challenged to a Duel directly by Gen Ankokuji, one of the disciples of the Gongenzaka Dojo who admired Ishijima and wanted to represent him, but he was protected by Gongenzaka.

For the past few years before the story, Yuya trained hard his Duelling skill and asked for help to Gongenzaka's dojo to find him opponents for Duel so he can fulfil the requirements to enter the Junior Youth Championship.

Discovering Pendulum Summon
Yuya and Gongenzaka were engaged in a Duel in You Show Duel School to recruit future students, they were interrupted when Yuzu accidentally broke the Solid Vision machine. Nico Smiley then came and offered Yuya a chance to fulfill his desire of Dueling Strong Ishijima in his father's place, but this upset Yuya who was reminded of his father's disappearance. Eventually, he left the school and sat by himself, remembering the time when his father told him to stay positive when he felt down. He later made his way to the Dueling arena to participate in Ishijima's Duel, dressed as a clown. Yuya sneaked up behind Ishijima and taunted him behind his back before revealing himself, much to Ishijima's shock and anger. Yuya apologized for his actions before commencing the Duel. He put up a good performance for the half of the Duel until Ishijima managed to counter Yuya's play with his own Action Card, "Miracle". "Odd-Eyes" was then destroyed by "Battleguard King", pushing Yuya to a corner and making him lose hope until he remembered his father's words, regaining the courage to continue. Suddenly, his pendant reacted with three of his Effect Monsters - "Stargazer Magician", "Timegazer Magician" and "Odd-Eyes Dragon", transforming them into Pendulum Monsters, while "Odd-Eyes Dragon" was transformed into "Odd-Eyes Pendulum Dragon". Using his his new monsters to support "Odd-Eyes Pendulum Dragon," he destroyed "Battleguard King" and wiped out Ishijima in a single attack, winning the Duel. Afterwards, he was swarmed by people asking about the Pendulum Summon that he'd performed, though he seemed unaware of the details himself and didn't seem to remember exactly what had happened.

The You Show Duel School received a flood of applicants, all eager to learn how to Pendulum Summon. Yuya and Yuzu had an exhibition Action Duel. On his second turn, Yuya attempted to Pendulum Summon again, but the Summon failed. Theorizing that it might only work when he was in a pinch, he urged Yuzu to attack him with all she had, but the Summon failed again and Yuzu defeated him. He showed Yuzu and the applicants his Pendulum Cards afterwards, annoying the applicants as they thought that Yuya might have cheated against Strong Ishijima and they couldn't use the Summon without the Pendulum Cards. All but Tatsuya left, though the boy believed in Yuya, and Gong encouraged Yuya to support his fans. Yuya agreed, vowing to master Pendulum Summoning. He finally did so, replicating the conditions of his Duel with Strong Ishijima after 291 Duels against Gongenzaka, though the ordeal left him sleeping through his math class the next day.

Yuya vs. Shingo Sawatari
After the day ended, Tatsuya, Ayu and Futoshi arrived, eager to see the Pendulum Summon. They were interrupted by a student of the Leo Duel School, Shingo Sawatari, who admitted he was a big fan of Yuya's Pendulum Summoning, and after learning that they were going to see a Pendulum Summon, offered the use of the Center Field at LDS. Shingo showed them around, and Yuya was impressed by the various courses the school had on different Summoning forms. At the Duel Field, three of Shingo's friends approached them, and Shingo asked if he could show them Yuya's Pendulum Cards. Yuya was reluctant, but he agreed, holding out "Stargazer Magician" and "Timegazer Magician". Shingo swiped the cards and showed them to his friends, then he stated that he was keeping them for himself, suggesting that Yuya Duel to get them back. With Yuzu, Ayu, Tatsuya and Futoshi held hostage, Yuya had no choice. The Duel didn't go well for Yuya since not only there were Traps that reduced the ATK of his monster but they also put his friends at risk. Shingo then proceeded to use the two Pendulum Monsters that he had stolen to Pendulum Summon three monsters himself, much to Yuya's shock. Yuya began to grieve for the sake of his friends, but regained his confidence when he drew "Block Spider", using it in conjunction with "Mimiclay" against Shingo to defend himself. Yuya later used "Empty Fishing" to regain his two Pendulum Monsters and used them to save his friends from falling before defeating Shingo. After losing to Yuya, Shingo sent his friends to take back "Timegazer Magician" and "Stargazer Magician", but they were intercepted by a boy named Sora Shiun'in, who knocked them unconscious with his lollipop stick and declared himself wanting to be Yuya's apprentice.

Yuya vs. Sora Shiun'in
The next day, Yuya woke up after having a dream about being the world champion, only to find that Sora had followed him home, eating breakfast with him and his mother after he sweet-talked the latter. As the day went on, Sora continued to follow Yuya to school, appearing in front of him and calling him "Teacher", even to the You Show Duel School where he asked Yuya to Duel him so he can see the Pendulum Summon. Yuya at first refused, but after Sora pleaded with his cute face, Yuya agreed under condition that if he win, Sora must stop pestering him and if Sora win, he can become Yuya's apprentice and following him around. As the Duel started, Yuya seemed to easily gain the upper hand until Sora performed Fusion Summon, summoning Des-Toy Scissors Bear, destroying Yuya's "Odd-Eyes Pendulum Dragon". However, Yuya able to turn the tide after realising that "Odd-Eyes" didn't go to Graveyard, but back to Extra Deck, countering Sora's monster with his Pendulum monsters and won the Duel. After the Duel, he reminded Sora of his promise, so Sora instead decided to become his friend, calling him by his first name. Despite Yuya's protests, an enthusiastic Shuzo accepted Sora into the You Show Duel School and went to get the paperwork. Yuya asked Sora where he'd learnt to Fusion Summon, with Sora claiming it was normal from where he came from, confusing Yuya that Sora might be a foreigner.

You Show Duel School vs Leo Duel School
Several days after defeating Shingo, Yuya and his friends were eating ice cream while waiting for Yuzu and Ayu, but only Yuzu came back. Ayu told him that Yuzu was trying to stop Shingo from getting his revenge on Yuya, prompting Yuya raced to the warehouse where Yuzu had been, finding her unharmed, only for Yuzu to ask was he the one who defeated Shingo, much to his confusion. This was furthered when the next day Yuzu abruptly asked Shuzo if their school taught Xyz Summoning, much to Yuya's and Shuzo's confusion. After it was clarified that they didn't, they heard Gongenzaka arguing with someone. Confused, Yuya found him with Shingo;s friends, who all claimed that Yuya had attacked Shingo and hospitalized him, much to Yuya's surprise and confusion, and furthermore, Yuzu had also witnessed the incident. Yuya denied that he'd attacked Shingo, but the conversation only intensified when Himika became involved. His friends were convinced that Yuya had not attacked Shingo, even Yuzu, who had been doubting her own conclusions. Regardless, she stated, Shingo had lost and their School's name tarnished. The group realized that Himika was using the incident as an opportunity to add the You Show Duel School to LDS when she proposed a Duel between schools, best out of three. If her Duelists won, she would buy the You Show Duel School. Yuya vowed to fight, refusing to let the Duel School that his father had founded with the intent to teach Entertainment Dueling be taken over by one interested in money and power. He requested to Duel first, despite Sora trying to do so, and ended up facing Hokuto Shijima, LDS's top Xyz-user.

Hokuto's tactic counter Yuya's Pendulum Summoning by returning "Odd-Eyes" to Yuya's hand, as well as barring Yuya's way when he attempted to find Action Cards. Hokuto's expertise with the Action Field puts Yuya at a disadvantage and purposefully in danger, and even though Yuya manages to withstand Hokuto's monster until it runs out of Overlay Units, Hokuto simply brings out another, then uses the first one as Xyz Material to Xyz Summon "Constellar Ptolemy M7". Hokuto again timed his attacks to hurt Yuya, resulting in a building collapsing around Yuya as he grabbed an Action Card. Yuya was able to survive, commenting that if he had fled, it wouldn't have been exciting, and he countered with the card, inflicting damage to Hokuto for the first time. Hokuto went into a rage for being damaged for the first time in 40 Duels, and reduced Yuya to 200 Life Points, raining down meteors on Yuya, who was only just able to dodge them. Yuya proceeded to switch his "Stagazer Magician" and "Entermate Turn Toad" around with "Entermate Trampolynx," allowing him to counter "Pleiades'" effect and keep "Odd-Eyes" on the field, then used "Magical Star Illusion" to boost the ATK of all of his monsters by their total Levels. The effect was applied to Hokuto as well, but since his Xyz Monsters had Ranks rather than Levels, he recieved no bonus, and Yuya proceeded to wipe out the rest of Hokuto's Life Points.

The next two Duels resulted with Yuzu lost against Masumi Kotsu and Gongenzaka tied against Yaiba. A furious Himika proposed a tie-breaker Duel between Yuya and Masumi, the two winners, and Yuya prepared to face her, but before they could begin, a mysterious grey-haired Duelist, Reiji Akaba arrived. He claimed that he would put an end to this. Yuya seemed to be in the lead due to Reiji's permanent magic card that reduced his own LP. However, Reiji turned the tide to his favour when he used counter magic to not only regain his LP but also perform Fusion, Synchro, and Xyz Summon all at one turn. Everyone were shocked further when Reiji also able to Pendulum Summon, cornering Yuya. Before they could continue, Reiji received a call from his employee, Nakajima, and he gave Yuya the win. He told Yuya his full name when asked before he departed.

Yuya vs. Shuzo
Yuya was shell-shocked that Reiji had been able to Pendulum Summon. Tatsuya encouraged Yuya to teach them about his Pendulum Summoning, but Yuya yelled that Pendulum Summoning wasn't his anymore and he tried to run off, only for Shuzo to stop him. Shuzo told him off for running, pointing out that reality wouldn't change if Yuya fled from it, despite the fact that other people could Pendulum Summon had shown up. Shuzo pointed out that one day the world could be overflowing with Pendulum Cards, given Reiji's status as the CEO of the Leo Corporation. He ordered Yuya to Duel him, so that he could beat Yuya's pessimistic personality into shape. They Dueled in Yusho Sakaki's signature field, and Shuzo told him he'd show Yuya what a real Entertainment Duel was like. Yuya protested at his Duels being called fake, and Shuzo claimed that Yuya's Duels were not comparable to his or Yusho's. Forcing Yuya to reveal his hand, Shuzo harassed him, and Yuya Dueled for a turn without using his Pendulums, despite having both his Magicians in his hand. When Yuya's attack failed, he claimed that Yusho's Duels were more entertaining than Shuzo's, a fact that Shuzo agreed with. Shuzo pointed out that Yusho's Duels weren't always like that and initially attracted criticism, but eventually, the jeers became cheers. He told Yuya that to open a door to a new world, one with courage had to push it, and Yuya had opened a new door called "Pendulum." But they wouldn't be exclusive to him anymore, soon anyone could Pendulum Summon. To prove it, he took control of the Magicians and used them to Pendulum Summon more monsters. Shuzo commented that Yusho would have been overjoyed and improved his skills, while Yuya was shocked instead, and encouraged Yuya to set and example and hone his skills. but ended his turn without attacking and returned the Magicians to Yuya (due to his card conditions). Regaining his confidence and taking a step forward with courage, Yuya defeated Pendulum Summon three monsters and used them to defeat Shuzo.

The next day, as he messily ate lunch with Yuzu, Shingo approached them, commenting that he heard Yuya attacked someone again, though he knew Yuya wasn't the culprit, and he called Yuya's Pendulum Summoning cowardly as only Yuya could do it. Shingo vowed to get his hands on the new Pendulum Cards being developed by LDS and defeat Yuya, saying that he'd be waiting at the Junior Youth Championship before departing. Yuya remembered that he couldn't join the Championship, as his win rate was only 56% rather than the required sixty. Yuya tried to find someone to Duel all day, but they all refused. Tatsuya worked out that if Yuya defeated his next four opponents, he'd be able to qualify. Yuya bemoaned the fact that his win against Ishijima was causing people to think he'd get a free pass, which was completely a misunderstanding since it was only an exhibition match. He then realized that there were four of his friends right there - but they all refused; Ayu, Tatsuya and Futoshi as they were only in elementary school, and Yuzu because she and Yuya had Dueled many times before and she'd already qualified. Yuzu suggested asking Gongenzaka for help, but Yuya decided against it, as Gongenzaka had helped him too much in the past and Yuya wanted to get stronger by himself.

He arrived at You Show to find Nico Smiley there, who offered him a free pass into the Junior Youth Championship as the Duel Committee acknowledge Yuya's victory against Ishijima. Yuya declined, not wanted to be given special treatment, but he was able to get Nico to set up his next four Duels. He then was asked by Suzho to find Yuzu, and he found her with Sora and Masumi at the warehouse. He was immediately interrogated by both Masumi and Yuzu regarding the Black-Masked Duelist, but had no clue what they were talking about. Sora mediated the situation by distracting Masumi and explained to Yuya that he'd been teaching Yuzu to Fusion Summon. When he explained that he'd found his next opponents, Sora asked Yuya about entering the Championship, and Yuya explained that if he won six Duels in a row, Sora would be able to enter.

Yuya vs. Michio Mokota
After reorganizing his Deck the following day, Yuya noted that his mother was bringing in more stray animals, including Sora, who was eating with them again. They wished each other luck, but Yuya ended up having to skip breakfast since the new recipe his mother was making was taking too long. He arrived at the Cuisine Duel School to Duel Michio Mokota, and they Dueled in the "Action Kitchen," a field that Michio demonstrated skillful knowledge of. Yuya was having a difficulty in getting Action Card since he didn't have any energy after skipping breakfast and he was distracted by how delicious-looking Michio's monsters were. Fortunately, Yoko arrived with Michio's recipe that she has changed, and Yuya eagerly devoured it, and then leapt for the Action Card again, using it in combination with his Trap to survive the attacks. On his next turn, he drew his "Illusion Balloons" Spell Card and Pendulum Summoned again, Summoning all five of his destroyed Pendulum Monsters from his Extra Deck. Michio returned all of his "Royal Cookmates" to his hand again and destroyed all five of Yuya's monsters, but Yuya had been counting on this, and he used this to trigger "Illusion Balloons," the balloons appearing as the breakfast Yoko had made for him. He excavated the top five card of his Deck, and the final one was his "Entermate Hammer Mammoth," which was thus Special Summoned with enough ATK to wipe out Michio's Life Points, winning Yuya the first of the four remaining Duels that he needed to qualify. Michio took the loss gracefully, telling Yuya he'd see him in the Junior Youth Championship.

Yuya vs. Eita Kyuando
As Yuya was due to Duel at the Quiz School the next day, after having several of Michio's recipes that had been prepared by his mother, he stayed up late watching quiz shows, but this had a negative effect on his concentration. The next day, while having a walk, he was suddenly pursued by three LDS students led by Mr. Sawatari, who still believed Yuya to be the person who had attacked Shingo. Fleeing, unaware of the reason behind his pursuit, Yuya was saved by the intervention of an Xyz Duelist, Shun Kurosaki, who proceeded to Xyz Summon a monster that dealt real damage to the LDS students and seal them in cards, while knocking Yuya himself out. Nico Smiley later found Yuya, who babbled about a monster that destroyed the area, but there was no visible evidence of the encounter. Nico asked if Yuya had been sleeping, and Yuya admitted that he'd stayed up all night doing quizzes, dismissing what happened as a dream.

Yuya then Dueled Eita Kyuando from the Cram Duel School. Although Yuya lost most of his Life Points due to the "Quiz" Action Cards, "Quiz Monkey", and "Sphin-Quiz", he eventually won using the effects of "Performance Resurrection - Reborn Force", "Entermate Curtain Call", and "Odd-Eyes Pendulum Dragon".

Growing Pendulum Summoning
The next day, Yuya remembered Nico Smiley congratulating him from his two recent Duels. Yuya noted that Nico didn't seem so excited, with Nico replying that it's the Pro Duelists' job to be excited. He told Yuya that the Entertainment Duelists surpassed the wildest imagination of the audience. Yuya took his pendant off his neck and swung it around. He restated surpassing the audience's imagination and how his father stole the hearts of his audience, too. Yuya remembered what Reiji said about seeing further evolution in Pendulum Summoning, and was frustrated about how he couldn't see it, though. He went to Shuzo and asked what he should do, with Shuzo replying that he should move forward. Yuya commented that if he didn't know which path to take, he couldn't move forward. Later, while reading a magazine, Yuya remarked on how Yuzu was learning Fusion Summoning from Sora. He bumped into Hokuto and Yaiba who were in hurry to the warehouse where Masumi found the culprit behind the LDS attack, with Yuya decided to follow them. The trio arrived at the crime scene, only to find Masumi, Sora, and Yuzu with her cards scattered across the ground. Yuya asked Yuzu what was wrong, but she only sobbed, saying she didn't know what's going on anymore. The LDS security then arrived, prompting Sora to suggest for them to leave before getting involved. Yaiba remarked to Yuya that he still needed two more matches to join the Junior Youth Championship. Yuya asked how he knew that, and Yaiba replied that he wanted to say good luck, although it might be difficult for him, and he left. Yuya then noticed Yuzu's "Fusion" card on the ground, and guessed she accidentally forgot about it.

Yuya vs. Mieru Hochun
Yuya was due to Duel Mieru Hochun the next day, but slept in and arrived late, bumping his head on his desk and mixing up his cards at his house and cartwheeling down the stairs to land in a position to see up Mieru's skirt. Mieru whacked him on the head with her crystal apple for that. Yuya's bad luck coninued into the Duel, drawing high-Level monsters and low Scales, leaving him with a dead hand and forcing him to pass, allowing Mieru to take an early lead with her Flip Effect Monsters, and then her Ritual Monster, "Tarotray the Sibylla." Fortunately, Yuya was able to draw "Timegazer Magician," allowing him to Pendulum Summon five powerful monsters and boost "Odd-Eyes Pendulum Dragon" to 3700 ATK, but his monsters were all frozen in Defense Position by the effects of Mieru's Flip Monsters, which "Tarotray" could freely trigger. Mieru then had "Tarotray" read Yuya's fortune, the Towers card, which indicated a destructive future for Yuya. Mieru told him to stop the match to avoid that future.

Yuya refused to let his dream be ended there, but Mieru used her Flip Monsters to set up a combo that wiped the field of his Defense Position monsters and dealt him damage. She continued to urge him to surrender, even sealing Yuya's draw with "Draw Lock," which Yuya would need to dispel with an Action Card. Yuya began to search, eventually finding one as the chandelier of the Duel Field began to collapse around him. Sprinting hard, Yuya was able to grab the card and survive the fall, apparently having changed his future. He drew on the next turn, but he'd drawn Yuzu's "Fusion," as was disheartened, believing that he couldn't use it. He then received a vision of a sealed monster, and he Pendulum Summoned again, then returned his "Magicians" to his hand and Summoned "Stargazer Magician," then fused it with "Odd-Eyes" to create "Rune-Eyes Pendulum Dragon," which was able to attack mulitiple times and win the Duel. He returned Yuzu's "Fusion" to her, and they shared a touching moment that was broken up by the infatuated Mieru, inciting swift rebuke from Yuzu.

Yuya vs. Gongenzaka
Waking up the next day, Yuya found both his house and the Duel School empty save Nico Smiley, who took him to the Gongenzaka Dojo to Duel Gongenzaka. Gongenzaka revealed that in order to get a serious match from Yuya, he'd arranged it so that they were both one win away from entering the Junior Youth Championship, much to Yuya's shock. He didn't know if he could defeat Gongenzaka like that, but their Duel commenced on the "Sword's Graveyard" field that Gongenzaka had Dueled Yaiba on. Gongenzaka brought out his "Big Benkei" early, and Yuya fought back with "Entermate Silver Claw," and Action Cards. But on his next turn, Gong proceeded to Synchro Summon "Superheavy Samurai Warlord Susano-o." Yuya was shocked that Gongenzaka had Synchro Summoned, and even more so when his father attempted to stop the match, believing that Gongenzaka had stolen the technique. Gongenzaka revealed that he had instead requested instruction from Yaiba, and he drove Yuya back with "Susano-o." Yuya assembled a hasty defense by Pendulum Summoning, and he was only barely able to survive the turn. He Pendulum Summoned again, bringing out "Hip Hippo" so that he could Tribute Summon "Odd-Eyes Pendulum Dragon," and was able to use his "Entermate Lizardraw" to draw "Entermate Trump Witch," thus allowing him to Fusion Summon "Rune-Eyes Pendulum Dragon." Though he defeated "Susano-o," Gongenzaka was able to revive it, so Yuya had to leap for an Action Card to pay the cost of his "Dangerous Draw," gambling everything on his next draw. He drew "Big Return," which allowed him to re-use his "Trump Witch's" effect to Fusion Summon "Beast-Eyes Pendulum Dragon," attacking to win the Duel. His friends, who had been secretly watching the Duel, congratulated him afterwards, including Gongenzaka, who reassured Yuya that he still had a chance to enter the Championship.

Opening Ceremony
The day of the Championship, Yuya stood on the bridge looking at the Dueling Arena, while swinging the pendant in front of him. He remembered the day before his father's Duel with Strong Ishijima. After the recollection, Yoko chided Yuya, telling him that she just got a call from Yuzu. She said that Yuya should be worrying there, pointing at the stadium. At the stadium, Yuya arrived just in time, butting heads with Gen Ankokuji, and he was selected to give the oath of fair play. Though he initially messed up, he composed himself and gave a speech about his father, earning the applause of the stadium. He was shocked to see Shun, the Duelist that had saved him from the LDS top team, standing among LDS students, who claimed that Shun had always been one of them. Yuya learned that his first match was to be against Shingo the next day. He watched Futoshi, Ayu, and Yuzu's Duels, supporting them all.

On the second day, a man carrying Gongenzaka's sash ran into Yuya, and another man snatched the sash up. Yuya and the first man gave chase, but Yuya had been lured into a trap by the two, who had been sent by Ankokuji to harm Yuya, thus distracting Gongenzaka during the match. Yuya was able to not only defeat them and get the sash back, but also entertain them with his "Hippo" cards. He arrived at the match and threw Gongenzaka's sash to him, and watched as Gong proceeded to defeat Ankokuji.

First Round
Yuya was up next against Shingo, who vowed to defeat him based on his misplaced grudges: first for stealing his Pendulum cards and use it to defeat him (which actually he was the one who stole it), second for having an Xyz user doppelgänger to hurt him (which was actually done by Yuto and Shingo wasn't hurt from the incident), and lastly was for attacking his father (which was actually done by Shun). Yuya was worried when Shingo claimed that Pendulum Summoning would be Yuya's downfall, remembering Shingo's promise to obtain LDs developed Pendulum Cards. Shingo used his new "Yosenju" cards to prevent Yuya from getting Action Cards, but Yuya was able to Pendulum Summon and counterattack with "Odd-Eyes Pendulum Dragon" and "Entermate Drum Kong." However, true to his words, Shingo proceeded to Pendulum Summon "Mayosenju Daibak" and complete his "Yosen Lost Tornado" combo, using the effects of "Yosen Tornado" and "Yosen Realm Whirlwind" to return Yuya's Pendulum cards to the Deck.

Despite being cornered, with Pendulum Summoning being used against him, Yuya was enjoying the Duel, setting his remaining cards and ending his turn, then dashing off to look for Action Cards, vowing that the Duel had only just begun. Yuya was able to rouse the crowd by drawing "Magician's Card," replenishing his hand. He brought out "Odd-Eyes" again and boosted it over the ATK of "Daibak", but was unable to destroy it. He then used the effect of "Entermate Trump Witch" to Fusion Summon "Beast-Eyes Pendulum Dragon," and again traded blows with "Daibak." Shingo obtained an Action Card that would win him the Duel should "Beast-Eyes" be destroyed, but Yuya had found "Miracle," allowing him to use the effect of "Beast-Eyes" to win the Duel. Afterwards, Shingo generously offered to Duel Yuya any time, and they waved to the crowd as Yuya mused that this was the type of Duel that he'd been wanting, and wondered if he'd gotten closer to his father.

Meeting Yuto and Yugo
He and Yuzu watched Sora's Duel with Shun worriedly, since they knew Shun to have been the serial attacker on LDS. He recognized Shun's monsters from when he'd encountered him, including "Raidraptor - Rise Falcon," and warned Sora to be careful, proven correct when "Rise Falcon," decimated Sora's field. He watched in horror as the Duel continued, turning the Action Field into a raging battlefield. As the Duel reached its climax, with Shun claiming victory Sora was injured by a falling building and hospitalized.

He remained with Yuzu and Gongenzaka at the hospital to keep an eye on Sora, where the three of them compared the facts, and Yuya learned about Yuto, a Duelist who resembled him and the real culprit behind the attack on Shingo, who somehow disappeared whenever her bracelet is glowing. Yuya mused that the conflict between Sora's people and Shun's seemed to be larger than an inter-school rivalry, but before they could talk further, they overheard the guards looking for Sora, who had escaped. After calling Shuzo, Yuya headed off to Central Park, finding Sora Dueling Yuto.

Yuyaundefineddecided to interfere after hearing Yuto’s intention to defeat Sora as the first step to save his friend, Ruri. He Pendulum Summoned "Odd-Eyes Pendulum Dragon" on his first turn, but to his surprise, he experienced a burning sensation in his chest as it faced off against "Dark Rebellion Xyz Dragon." He attacked with the intent to destroy both monsters and revive "Odd-Eyes" next turn, but Yuto blocked the attack, playing around the effect of "Timegazer Magician." Sora angrily told Yuya to get lost, claiming that Yuto was his prey. Yuya demanded answers, revealing what Yuzu had told him. Before Sora could continue, he was returned to the Fusion Dimension forcibly.

With Sora disappeared, Yuto no longer has any reason to continue the Duel and both decided to call off the Duel. Yuto then explained about the four Dimensions to Yuya as well as the destruction of his homeland at the hands of Fusion Dimension. Yuya was skeptical, but told Yuto that Dueling is not a tool for conflict, but to bring happiness to people. They were interrupted by the arrival of a Duelist on a Duel Runner, who crashed into a streetpost, and revealed that he too resembled Yuya and Yuto, whom Yuto referred as “Pawn of Fusion”. The Duelist stated that his name is Yugo and challenged Yuto for a rematch since they were interrupted before.

Yuya watched the Duel in shock as the Duelists ran around agily, and experienced the same burning sensation when Yugo, a Synchro user, called out "Clear Wing Synchro Dragon." The sensation intensified when Yuto retaliated with "Dark Rebellion Xyz Dragon," causing the two Duelists to seemingly become possessed and violent. Yuya managed to calm Yuto down by reminding him of his homeland, but was unsuccessful in calming Yugo, who proceeded with his battle phase. Before the shockwave could hit Yuya who was defending Yuto behind him, Yuto pushed Yuya aside, taking the shockwave in his stead. Yuya quickly rushed to Yuto’s side to help him, but then his “Odd-Eyes” and Yuto’s “Dark Rebellion” resonated, engulfing them in a bright light. Yuto entrusted Yuya with his “Dark Rebellion”, telling him to bring smiles with Duel using his power before he and Yugo disappeared. Yuzu, who shortly arrived on the scene, found Yuya collapsed.

Second Round
Yuya remained unconscious for two days, and when he finally awoke, he was surprised to hear it. Yuzu informed him that the first round of the Maiami Championship was ending today. He learned that Mieru had lost in an OTK and that Futoshi had also been defeated by Reira, who had used Synchro Summoning this time. When Yuzu mentioned that he might know all about Fusion, Synchro and Xyz Summoning, Yuya told her what Yuto had told him about the world being made up of four dimensions, and that the Fusion Dimension, where Sora lived, and the Xyz Dimension, where Yuto and Shun lived, were at war. He also told her that he had found Sora Dueling against Yuto, until he watched Sora disappear. Then he told her about Yugo, who also looked like him, and who Yuto had called a "Pawn of Fusion". He theorized that maybe Yugo had been the one who captured Ruri, then went to look at the "Dark Rebellion Xyz Dragon" card Yuto had given him. When Yuzu asked him about it, he said that Yuto had given it to him after saving him from "Clear Wing Synchro Dragon", and that he remembered nothing after that. He also wasn't sure what happened to Yuto, or why he gave him "Dark Rebellion Xyz Dragon". He expressed his confusion about why both Yuto and Yugo looked just like him, and was surprised when Yuzu told him that Ruri supposedly also looked like her. He realized that Shun may know something about the four dimensions, and they both went to Centre Court to ask him.

When they arrived, Yuya was greeted by Gongenzaka, who hugged him, and Shuzo, who said that both he and Gongenzaka were really worried about him. Futoshi, Ayu and Tatsuya also arrived and were happy to see that he was okay. Futoshi apologized for losing his Duel against Reira, saying that he was so shocked by Reira's Synchro Summon that he got the shivers. Yuya consoled him by saying that he should give Reira the shivers next time, until he suddenly remembered Sora claiming that there were no second chances in battle, and froze. Mieru then appeared, delighted that he had woken up, and went to kiss him, but he simply dodged her and went to talk to Masumi, Hokuto and Yaiba, who were also there. He asked to see Shun, as he had a lot of questions to ask him, but Yaiba told him that Shun wouldn't even give him the time of day. He suggested that Yuya and his friends should come and watch his next match, and they did. Yuya watched in shock as Isao Kachidoki, Yaiba's opponent, violently attacked Yaiba in competition for Action Cards and emerged as the victor. He was further amazed to discover that he would face Isao in the next round. He reflected that Yuto had told him to make everyone smile with his Dueling, and he resolved to do so against Isao.

After watching Gongenzaka's victory against Yuzo Tanegashima, Yuya proceeded to Duel against Isao. Isao's violent Dueling method put Yuya at a disadvantage by preventing him from getting any Action Cards. Yuya finally managed to obtain one, but this came at the cost of his Life Points being reduced to 100. Cornered and at the edge of defeat, Yuya once again experienced a burning sensation in his chest and then saw of vision of Yuto, during which Yuto's soul merged with Yuya's. After this vision, Yuya's personality drastically changed. He used the Action Card he got to clear his cards and then Pendulum Summon "Entermate Lacoodown" and "Entermate Silver Claw", which he then used to Xyz Summon "Dark Rebellion Xyz Dragon", much to everyone's shock. Without any hesitation, Yuya used its effect to defeat Isao, which stunned the whole audience. Once the Duel was over, Yuya returned to normal. Seeing Isao kneeling in defeat, Yuya tried to help him stand, but Isao rejected his help. Yuya then turned to his friends and the audience who were shocked by Yuya's actions, making Yuya question himself about what he had done.

The next day, Yuya and the others were watching Yuzu's match. Unlike his friends, Yuya was not very enthusiastic in cheering Yuzu on because he was still depressed with his previous victory against Isao. However, Yuya started to regain his resolve when he saw the smiles on the audiences' faces while watching Yuzu's Duelling and once again remembering Yuto's words to Duel with smiles. Overcoming his depression, Yuya smiled happily at Yuzu when she won, finally regaining his spirit.

Battle Royale
At the final round of the championship, which was a Battle Royale Duel, Yuya was up against two Ryozanpaku Duelists, Ken Umesugi and Makoto Takeda. Like in the Duel against Isao, their violent Dueling methods not only prevented Yuya from getting Action Cards but also prevented him from attacking them. This quickly put Yuya at a disadvantage since he was also afraid of losing himself like when he Dueled Isao, until a LDS transfer student, Dennis Macfield, saved him and joined the Duel as Yuya's tag partner. Yuya was exasperated by Dennis' admiration for his father. With Dennis' help, the tide turned in their favor. Dennis allowed Yuya to finish the Duel. Yuya Pendulum Summoned "Entermate Silver Claw" and "Entermate Whip Viper". The moment he Summoned them, "Dark Rebellion Xyz Dragon" appeared in Yuya's mind, which almost caused him to enter his berserk state, if not for Dennis' moral support. Feeling assured, Yuya successfully summoned "Dark Rebellion" without losing himself and defeated both Ken and Makoto with the help of Dennis' "Entermage Trapeze Magician".

Parting ways with Dennis, Yuya met Shun at the Ancient Ruins. Shun immediately asked Yuya what happened to Yuto and accused the former that he had done something to his comrade since Yuya had Yuto's "Dark Rebellion Xyz Dragon". Yuya answered that Yuto entrusted the card to him and told him to bring smiles with his Duels. Before Yuya could explain further they were interrupted by the Knight of Duels Duelists, who were Duelling each other and purposely surrounded Shun so their attack would hit him without getting penalized. Yuya, who was beside Shun, also got caught in the attack and blown away. Sora and the Obelisk Force then appeared, shocking Yuya. He called out to Sora, but he was ignored.

While Sora took Shun elsewhere to Duel, the Obelisk Force defeated the Knights of Duels and sealed them into cards, horrifying Yuya. The event triggered a vision of Yuto's memory when Heartland was invaded. Overwhelmed by the memory, Yuya succumbed to his rage and challenge the Obelisk Force. The enemies' cowardly tactics prevented Yuya from using Action Cards or avoiding their attacks. The Obelisk Force then taunted Yuya by mockingly showing the Knight of Duels' Duelists' cards and told him he will share the same fate, enraging Yuya further. As Yuto's memory filled his mind, Yuya and Yuto's soul merged again, causing him to summon "Dark Rebellion Xyz Dragon" and attack Red Obelisk Force. This started to panic the Obelisk Force and they counterattacked with their monsters until Yuya's LP reduced to 800, but despite the damage he took Yuya remained unscathed and instead smiled wickedly.

On his turn with 200 LP remaining, Yuya Pendulum Summoned "Odd-Eyes Pendulum Dragon" and then used the Pendulum effects of "Destruction Magician" and "Creation Magician" to make "Dark Rebellion Xyz Dragon" a Level 7 monster. He overlaid "Odd-Eyes Pendulum Dragon" and "Dark Rebellion Xyz Dragon" to perform a new Xyz Summon, summoning "Odd-Eyes Rebellion Dragon" and defeated the Obelisk Force in an instant. However, even after defeating the Obelisk Force, Yuya proceeded to go to where Shun and Sora were, ignoring a falling pillar that would have crushed him had Gongenzaka not protected him. Gongenzaka and Mieru took Yuya to the Jungle area where he was restrained by Gongenzaka, Michio, and Teppei while Mieru used her crystal ball to see what was inside Yuya's heart. She found that there were two hearts inside him, along with a pitch black darkness. Yuya went unconscious and later awoke without remembering his duel against the Obelisk Force. He then explained what happened prior to entering Berserk Mode to Gongenzaka and the others. Hearing Mieru's explanation about the presence of another heart inside him, Yuya realized that the other heart was none other than Yuto and his anger for what happened during Academia's invasion was what triggered his change. This made Yuya wonder why Yuto, who entrusted him "Dark Rebellion Xyz Dragon" so he could make people smile with his Duels, would let him be overwhelmed by so much anger.

As he was resting, Yuya contemplated of Yuto's memories that he had saw and finally understood Yuto's anger and sadness, believing that Yuto wasn't lying when he said to make everyone and their future smile with his Duels and the one who was trying to consume him is the darkness that also within him. This made Yuya afraid for a moment until he was reminded by his father's encouraging words, making him even more resolute to Duel with the way he believed. Deciding to find his other friends out of worry, he and Gongenzaka split up with Michio and Teppei. They were then approached by Dennis who informed them where Yuzu was, but Yuzu was transported with Yugo through her bracelet's power just as Yuya arrived.

Yuya and Gongenzaka continued their search at the Ancient Ruins, but didn't find Yuzu there and proceeded to the Volcano area, only to find Sora Dueling against Hikage. Yuya immediately asked Sora to stop by shouting at him until Sora finally responded that they would talk after he defeated Hikage, which angered Yuya. Gongenzaka stopped Yuya when he was about to interfere. He pointed at Serena, whom they mistook for Yuzu, Dueling against the Obelisk Force with Tsukikage and Shun. Yuya started to be consumed by the darkness when he witnessed Michio and Teppei being sealed into cards, followed by Hikage who lost to Sora. This caused Yuya to be momentarily taken over by darkness and he angrily confronted Sora, telling him that he was wrong. However, Yuya returned to his senses after hearing Yuto's voice that reminded him of their wish. Determined to bring back Sora's smile, Yuya challenged Sora to a Duel, which Sora accepted. He took Yuya to another side of the area so no one could interfere with their Duel.

Rematch Against Sora
Believing that Sora's smile when they first Dueled was genuine, Yuya tried to make Sora see the error of his view about Dueling, but Sora just ridiculed Yuya's belief and persisted that Dueling is to continue fighting. This made Yuya question if they were not friends anymore, which Sora confirmed because to him, his goal and victory was more important than friendship. This didn't stop Yuya from trying to change Sora's mind. He Xyz Summoned "Dark Rebellion Xyz Dragon" and Pendulum Summoned "Odd-Eyes Pendulum Dragon" with "Destruction Magician" and "Creation Magician". He then used the effects of his "Magicians" to make "Dark Rebellion" a Level 7 monster. Yuya hesitated for a moment to Summon "Odd-Eyes Rebellion Dragon", but decided to trust Yuto who told him to bring smile with Duel and Summoned it. He used its effect to destroy two of Sora's three monsters. The Xyz Pendulum Monster excited Sora, and Yuya pointed out Sora's excitement to express that Duel is for fun.

Yuya then attacked using "Odd-Eyes Rebellion Dragon", which Sora countered with the Action Card "Flame Chain" to lower its ATK, but Yuya countered back with his own Action Card, "Flame Power". As the attack of "Odd-Eyes Rebellion Dragon" was about to hit, both Yuya and Sora tried to reach an Action Card, but the Battle Royal reached its time limit, dismissing the Action Field and thus, leaving the Duel unfinished. Yuya finally noticed that the rest of his friends were present as well before calling out to Serena whom he still mistook as Yuzu until Serena made it clear herself. Thinking that Yuzu might have been turned into a card, he turned to Sora, but Sora returned to his own dimension before Yuya could question him. Reiji then arrived with Shingo and both revealed that the Battle Royal served as a test to determine Duelists suitable to fight the Academy and the Fusion Dimension.

Rematch Against Reiji
Once Reiji revealed that he had been watching the battle and let them fight to determine who could survive the battle against the Academy, Yuya broke into tears as he thought about Yuzu, Michio, Teppei, and all the Duelists who had been turned into cards. A furious Yuya blamed Reiji for what happened to the others and tried to punch him, but Reiji easily caught his fist and instead proposed for them to Duel since they were Duelists, which Yuya accepted. Reiji activated "Future Metropolis Heartland" for them to Duel on, which reminded Shun of his homeland tragedy. Declan asked what happened before at Xyz Dimension, but Shun couldn't say it, prompting Reiji to tell them what happened. However, before Reiji could elaborate any further, both Yuya and Yuto, still in Yuya's body, shouted at him to stop and start their Duel. Reiji immediately performed Fusion, Synchro, and Xyz Summons at once and inflicted 2000 damage to Yuya with "D/D/D Blaze Overlord Temujin", slightly injuring him. Yuya asked Reiji if he was satisfied with how many people were defeated and how many people survived from the Battle Royale, while declaring that they were not his puppets. Yuya then recalled how Yuzu helped him on his Pendulum Summoning and how she tried hard to become stronger, so he would do the same. He proceeded to Summon "Beast-Eyes Pendulum Dragon" and "Rune-Eyes Pendulum Dragon". Reiji revealed that he knew all along that Sora was from the Academy and speculated that Yuya's ability to Summon two new Fusion Dragons was possibly from Yuzu, who learned Fusion Summon from Sora, which meant that Yuya gained his Fusion Summon ability from the Academy. Yuya replied that he'd learned Fusion Summoning because he'd seen Yuzu learn Fusion Summoning to defeat Masumi. He managed to destroy all three of Declan's monsters and inflict 2100 damage to Declan with "Rune-Eyes". However, before Yuya could use "Beast-Eyes" to land the finishing blow, Reiji saved himself by activating the Trap Card "D/D/D Contract Modification" in order to negate the damage.

Reiji told Yuya that while he understood how strong Yuya's feelings for Yuzu were, feelings alone were not enough in true battle and he formed the Lancers so they could win without such naïve feelings. Yuya insisted that he had no intention to become a Lancer, but was surprised when Reiji asked if he didn't want to save Yuzu, implying that Yuzu wasn't sealed in a card. He further goaded Yuya to fight by telling him to defeat him first before rescuing Yuzu from the Academy. Ending his turn, Yuya was shocked when both his "Rune-Eyes" and "Beast-Eyes" were destroyed by Declan's "D/D/D Wave Overlord Caesar, leaving his LP at 1800. Yuya once again asked what exactly happened to Yuzu, but Reiji reminded him of their Dueling conditions; Yuya must make him repent by defeating him in Duel in the place of everyone who had been sealed into cards. This brought the memories when Michio and the others were sealed into cards and the tragedy of Xyz Dimension, causing Yuya to nearly enter Berserk Mode, but he barely suppressed it. He then summoned "Dark Rebellion Xyz Dragon" to destroy Declan's "D/D/D Caesar Ragnarok the Wave Complete Oblivion Overlord", but this came at the cost of "Odd-Eyes" that Declan had used to increase his monster's ATK, saving his LP.

Reiji then began his counterattack and successfully destroyed "Dark Rebellion" with "D/D/D Kali Yuga the Twin Dawn Overlord", reducing Yuya's LP to 800 and also injured Yuya further. Gongenzaka and Mieru intended to help him, but Yuya told them to stay back because this is his, Yuzu's, and Yuto's Duel. He stated his resolution that he would definitely save Yuzu and fulfil his promise with Yuto, declaring he must not lose to someone who would Duel for toying or hurting people. In a last ditch of effort to defeat Reiji, Yuya Xyz Summoned "Odd-Eyes Rebellion Dragon" and seemingly gained the upper hand. Unfortunately, Reiji used his monster effect to weaken "Odd-Eyes Rebellion" and increased his monster's ATK to destroy "Odd-Eyes Rebellion", defeating Yuya. Reiji reminded Yuya that he couldn't save Yuzu with his naive resolution, but he would let him go since Yuya's mastery of Pendulum Summoning was necessary for Lancers to fight the Academy. Frustrated at his loss, Yuya swore that he needed to become stronger to save Yuzu.

Powers and Abilities
Berserk ModeLike his dimensional counterparts, Yūya has the ability to enter Berserk Mode. This state is triggered unconsciously, with Yuya having no recollection of what happened while entering the state. Unlike Yuto and Yugo, the state was triggered not because Yuya being influenced by his Dragon, but rather it was initiated by Yuto who was residing in his body. After witnessing Yuto's memories of the day the tragedy befell his homeland, Yuya's main trigger for entering Berserk Mode is whenever he's remembering Yuto's memory or anything that reminds him of the tragedy. After Yuya was aware of the existence of the two souls within him, Yuya gained a degree of control of Berserk Mode either by remembering his promise with Yuto or by sheer force of will. There are two stages of Yuya's Berserk Mode:
 * First Stage:  Berserk Yuuya appears.jpg this stage, Yuya's hair became frizzled and his pupil glowing. Yuya's Duelling skill significantly stronger with more stable emotion despite overwhelmed by anger. Yuya's ability to create new Pendulum cards with his pendant is also strengthened while in this mode, such as creating Destruction Magician, Creation Magician, and Odd-Eyes Rebellion Dragon.
 * Second Stage:Berserk Mode Second Stage.png this stage, Yuya's hair frizzled up and his pupil glowing red and white. This stage was caused by Yuto's hatred for the Fusion Dimension gave birth to an unknown darkness that further strengthening Yuya's Berserk Mode, but this comes at the cost of Yuya slowly losing his humanity with his only objective is to defeat his enemies at any cost. While in this stage, Yuya continuously emit black aura and able to unleash a powerful shockwave that is beyond normal for someone from Standard Dimension.

Duels
In episode 8, Yūya's information shows he has dueled 46 times.
