Sora Shiun'in

Sora Shiun'in ( Shiun'in Sora), known as Sora Perse in the Dub version, is a character in the Yu-Gi-Oh! ARC-V anime. Interested in the Pendulum Summon Yūya created, this mysterious boy decides to become his apprentice. During his first Duel against Shun, Sora is revealed to be a soldier of Academia, a "Duel Soldier" training facility in the Fusion Dimension. As a soldier of Duel Academia, he swears loyalty to Leo Akaba and his plan to "unite the dimensions" despite his friendships with Yūya and Yuzu Hīragi. With encouragement from Yūya and Yuzu, Sora eventually realized he was hurting people and reluctantly abandoned his old ways. Since then, he has formally turned his back on Academia and becomes a member of Lancers.

Appearance
Sora is a short, young boy with light cyan hair, that is tied up and spiked out and light green eyes. He wears a blue jacket with a yellow and orange trim over a black t-shirt. He also wears a pair of light gray cargo shorts over long white socks and brown shoes. Sora has also been shown to carry a pink/white lollipop around with him.

Sora has also been noted by several characters as being extremely cute to the extent that they will side with him or give him what he wants, such as Yōko Sakaki who gave him Yūya's pancakes and Shūzō Hīragi who changed the field that Sora and Yūya were Dueling on simply because Sora didn't like it.

Despite his small size, Sora demonstrates an incredible degree of athleticism, being able to knock out three boys much larger than himself using only a lollipop stick, and later displays incredible jumping ability to quickly snatch Action Cards during Duels.

Personality
Sora is first shown to be a huge fan of Yūya, to the extent of obsession. This is shown when he constantly follows Yūya around, wanting to see Pendulum Summoning first hand. At first Yūya declines, causing Sora to spy on Yūya and continuously bother him until he gives in. Sora has also been shown to use his cute appearance to win others over to his side and get his own way. However, it does not seem to work on Yūya who only agrees to Duel with him if Sora stops following him around. Sora is also extremely childish and persists until he gets his own way. Sora has a habit of misunderstanding situations, often asking "Did I get it wrong?" in response to other peoples' reactions. However, he later becomes more secretive, making sarcastic comments toward the students of Leo Duel School.

Sora also shows exceptional knowledge of Duel Monsters for his age, including the different styles of Summoning and can strategize accordingly. However as such, he does not take Dueling seriously unless there is a Duel or Duelist that excites him, and ultimately, this is what motivates Sora: His own entertainment. It is seen that Sora is much more serious and malevolent than he actually shows, as seen when he was considering going all-out against Shun he let out a malicious grin, making him look noticeably more menacing. As the Duel progressed against him, he slowly descends into madness, subsequently bringing out more morbid Fusion Monsters and violently attacking his opponent, while slowly revealing more of his horrifying nature as he explains how much he and his people enjoyed "hunting" Shun and his comrades, simply because it is a "fun hunting game", while showing some disgust towards Shun, calling him "Xyz scum." He is infuriated by his loss against Shun, showing he has a superiority complex and a huge ego. His pride can be seen earlier: he derides LDS Fusion Summons and believes that Yuzu would be the clear victor in a match against them if she uses the techniques that he taught her, and after Yūto told Yuzu that "Fusion" did not suit her, Sora was off ended enough to challenge Yūto to a Duel.

However, deep down it seems that much of Sora's personality comes from his attachment towards the Fusion Dimension, as he truly considers the invasion of the Xyz Dimension to be a "gallant" battle, and that the only reason he could not allow himself to lose is because it would sully their honor. Being one of Academia's top students and trusted with their mission, he is very strict with himself, thus his behavior is likely a result of believing he is both honoring his comrades and doing right. This belief makes him indifferent to the horrible actions of the Academia. Not caring that they destroyed innocent lives in Heartland and instead seeing it as a step in uniting the dimensions.

His meeting with Yūya and Yuzu and their growing friendship made Sora's loyalty for the Academia starting to waver. He still insisted that he will always be part of Academia as he feels bound to the organization and still believes that Leo's goal to unite dimensions is the right thing to do, but eventually he couldn't bring himself to fulfil his mission at the cost of Yūya and Yuzu, whom he has considers as his first and true friends, leading to his defection.

He has sweet tooth, as he is obsessed with sweet foods or candies to the extent that he is rarely seen not eating them, even to the extent that he eats during lessons. Whenever he is serious or angered he tends to bite his candies rather than keeping it on his mouth.

Etymology
This character's name, "Sora", can be confused with that is also read "Sora" and is a name, means sky. The Kanji characters, 素良 (The first can be literally be translated as "elementary" or "prime", while the other is "good"), are unusual to make the "Sora". Shiun'in means "Purple Cloud Yuan". The masculine pronunciation of Sora (素良) is "Motoyoshi" and "Sora" is the feminine pronunciation of 素良.

Past
Sora attended Academia in the Fusion Dimension. He trained to become a Duel soldier. He and his classmates were solely focused on training and Sora made friends with none of them.undefined

Eventually, he made it to the top of an his class and was selected to be sent to Standard with a special mission.undefined

Pre-Maiami Championship
When Yūya and his friends went to the Leo Duel School, Sora passed Yūya as he was looking at the school's curriculum. He stopped for a moment to look at Yūya before carrying on down the corridor.undefined He later watched Yūya's Duel with Shingo Sawatari, amazed by how the latter managed to perform a Pendulum Summon. He continued to watch the Duel and was excited when Yūya managed to retrieve his "Stargazer Magician" and "Timegazer Magician". After the Duel finished, Shingo attempted to get his friends to assault Yūya and his friends, but was stopped by Sora who knocked them unconscious with his lollipop stick. He then introduced himself to Yūya and declared himself Yūya's apprentice, shocking him and his friends in the process.undefined

The next day, he followed Yūya home to his house, gaining entry by telling Yōko Sakaki that he was Yūya's apprentice. Yūya immediately denied it, and was shocked that Sora had both lied to get into his house and was eating breakfast there. Sora claimed it wasn't that big of a deal and that Yūya's "sister's" pancakes were delicious. Yōko's reaction caused Sora to realize he'd slipped up, and he immediately flattered her, claiming that she looked so young and beautiful he thought she was Yūya's sister. Yōko, appreciating the praise, gave him Yūya's pancakes as well. After that incident, Sora followed Yūya to school as Yūya was explaining what Sora was doing to Yuzu, stating that wherever his teacher went, Sora would follow. Yūya reminded him that he never made Sora his apprentice, but Sora begged him to make Sora his apprentice, expressing an admiration for Yūya's Pendulum Summoning. Yūya explained that one needed Pendulum Cards to Pendulum Summon, so Sora begged Yūya to show him. He tried his flattery tactics again by asking Yuzu to convince Yūya to show him a Pendulum Summon as he thought she was Yūya's girlfriend, however, this led to both denying it and Yūya accidentally insulting Yuzu, and Yūya being swatted by Yuzu's fan, to Sora's surprise and concern. He spied on Yūya in class through binoculars, wondering why he was making such a serious face, and continually harassed Yūya throughout the day. When Yūya went to the You Show Duel School, Sora was there as well, having claimed again to be Yūya's apprentice. He requested to Duel Yūya, who refused (and thus Sora gained the sympathies of everyone present) until Shūzō Hīragi convinced him otherwise. Yūya then imposed a condition on the Duel: If he won, Sora would stop following him around and trying to be his apprentice, but if Sora won, Yūya would take him on as an apprentice. The Duel began, but Sora was displeased by the choice of the "Wild West Duel Town" Field Magic Card, and he requested a fun one, so Shūzō changed it to "Sweets Island".

Duel Against Yūya
Sora began to swarm the field with his "Toypot," but his attacks were stopped by Yūya, who had been collecting Action Cards while "accidentally" crashing into the scenery. Sora attempted to grab an Action Card himself, only for Yūya to snatch it away. Yūya proceeded to Pendulum Summon during the next turn, much to Sora's excitement, and he reduced Sora to 1800 Life Points with a single attack from "Odd-Eyes Pendulum Dragon." Sora then decided to play seriously, Fusion Summoning his "Death-Toy Scissors Bear".undefined He took out Yūya's "Entermate Discover Hippo" to reduce his mobility and equipped it to his "Death-Toy Scissors Bear" to power it up. When Yūya tried to counterattack, Sora used two copies of "Jack in the Box" to by pass the effect of "Timegazer Magician," weakening "Odd-Eyes." Sora then equipped his "Death-Toy Scissors Bear" with "Toy Parade" to allow it to attack multiple times for each Equip Card it had equipped, a combo that would allow him to win the Duel. Yūya attempted to grab an Action Card, but Sora revealed previously unseen agility and snagged it himself. He then used it to prevent Yūya's own Trap Card from affecting "Death-Toy Scissors Bear" and destroyed "Odd-Eyes." With Yūya despondent and "Odd-Eyes" destroyed, Sora attempted to equip the Dragon to "Death-Toy Scissors Bear," but to his surprise, he was unable to. Yūya then began laughing, and he also realized that "Odd-Eyes" had been sent to the Extra Deck instead of the Graveyard, preventing it from being equipped. Sora ended his turn, and Yūya weakened "Death-Toy Scissors Bear" on his next turn with "Entermate Sword Fish" and "Entermate Cheermole" before destroying it with "Odd-Eyes," which he had Pendulum Summoned from the Extra Deck. Sora had lost, and agreed to honor his promise, but he decided to simply become Yūya's friend instead, calling Yūya by his first name (much to Yūya's anger) and enrolled into the You Show Duel School. Yūya attempted to find where Sora had learned to Fusion Summon, seeing as he hadn't been to LDS, but Sora evasively replied that it was normal where he came from, irritating Yūya once again.

You Show Duel School vs. LDS
He continued attending You Show Duel School, and when LDS Chairwoman Himika Akaba arrived, claiming that Yūya had attacked Shingo and that the two Duel Schools would Duel to settle the ownership of the You Show. Sora nominated himself to represent You Show, pointing out to Gongenzaka that he wasn't technically a You Show student. He wanted to Duel first, but Yūya instead went first, facing Xyz user Hokuto Shijima.undefined During the Duel, Sora protested that it wasn't very entertaining, recieving swift rebuke from Yūya in response. He also explained about Xyz Monsters and Ranks to Ayu, Futoshi and Tatsuya. After Yūya defeated Hokuto,undefined Yuzu was up next, facing Fusion user Masumi Kōtsu. Unfortunately, Yuzu lost the Duel, and Gongenzaka encouraged Sora to win the third Duel against Synchro user Yaiba Tōdō. Claiming that the Duel disinterested him, Sora instead allowed Gongenzaka to Duel Yaiba, much to Gongenzaka's happiness.undefined As with the previous Duels, he slyly commented from the sidelines regarding Dueling information that the children weren't aware of, musing that with only 100 Life Points and no cards in his hand "little-Gon" didn't have a chance to win, until Gongenzaka's use of his "Superheavy Samurai Soul Break Armor" monsters surpassed Sora's expectations and caused him to drop his lollipop in shock. Gongenzaka ended the Duel in a draw, so Himika proposed a tiebreaker between Yūya and Masumi. A mysterious grey-haired Duelist, Reiji, revealed himself, stating that he would put an end to this.undefined He used "DD" monsters against Yūya, Sora noting that the title stood for "Different Dimension". He was shocked when Reiji performed a Fusion Summon to bring out "DDD Blaze King Temujin." Despite Reiji being set up to take 4000 damage from his own cards, Sora wasn't convinced that Reiji was overconfident enough to take the risk and he was proven correct.undefined Reiji later set himself up to take 3000 damage, enough to wipe him out, but again, Sora knew that Reiji would evade the damage. But even Sora was shocked when Reiji unveiled his own Pendulum Monsters and gained an edge in the Duel. Fortunately, a call regarding an LDS teacher reached the ears of Reiji, who revealed his name and forfeited the Duel before departing.undefined Sora was impressed at Reiji's Pendulum Summoning, and as Shūzō reassured the students that they'd saved their Duel School, Sora pointed out that only Yūya had contributed to doing so. Tatsuya, Ayu, and Futoshi immediately rebuked him, pointing out that he couldn't complain because Sora didn't fight for them. Sora brushed off the remarks and walked off.undefined Yuzu later found him trying to get into LDS to Duel Reiji, whose strength had interested Sora. She pointed out that it wouldn't be that easy, something that Sora had noticed earlier when he'd seen guards all over the place. Yuzu took Sora to the warehouse where Yūya had apparently attacked Shingo, and begged him to teach her to Fusion Summon. Sora was quite bewildered, asking if this had been because Yuzu lost to Masumi.

Qualifying for Maiami Championship
Sora wasn't sure if it was okay to do so, but he eventually gave Yuzu a "Fusion" card and explained to her how to Fusion Summon. Before the explanation could progress further, he noticed a masked Duelist eavesdropping and chased him around the warehouse before clashing with the Duelist using their Duel Disks. Sora noted that the Duelist "wasn't from around here" and the Duelist replied that Sora wasn't either. Yuzu then spoke up, remembering the masked Duelist from before, much to Sora's surprise. Yuzu explained that the Duelist had attacked Shingo, and Sora asked him if he was behind the recent incident as well. Before they could get any info out of the Duelist, a vengeful Masumi arrived, ready to Duel the masked Duelist for what he'd allegedly done to Professor Marco. She revealed that the Duelist was an Xyz user, to Sora's interest. Yuzu and Masumi argued over who was talking to the masked Duelist, and Yuzu's bracelet activated, causing him to vanish while they weren't looking. An instant later, Yūya arrived, having been looking for Yuzu and he was surprised to see everyone else there. When Masumi interrogated Yūya, believing him to be in league with the masked Duelist, Sora distracted her by claiming that he'd seen the Duelist run off. Sora explained to Yūya that he was giving Yuzu Fusion Summoning lessons. Yūya revealed that his next four Duels had been set up to allow him to qualify for the Junior Youth Championship. Sora decided to qualify too, being told that he had to win six Duels in a row to do so and deeming it an easy task.undefined After eating breakfast at Yūya's house again and conversing with him, Sora set off to qualify, accompanied by Yuzu, and he defeated a sumo wrestler Duelist with his "Death-Toy Scissors Bear".undefined He defeated his second Duelist, a performer Duelist, but noticed that Yuzu was still preoccupied and not paying attention to his Dueling.undefined He Dueled Yuzu in a practice Duel, but she failed to Fusion Summon as she'd placed her Fusion Monster in her Main Deck. Afterwards, Sora pointed out that he'd been Fusion Summoning so that Yuzu could get some practice, claiming that he could have beaten his opponents without it, and wondering if she'd been thinking about the masked Duelist again. He wanted to Duel him, but Yuzu warned him about the Duelist's ability to inflict damage outside of an Action Duel. Yūya arrived, prompting Yuzu's bracelet to glow again and warp the eavesdropping masked Duelist away.

Having dinner at Yūya's house, in response to being cautioned for his carefree attitude towards his opponents, Sora told him to be careful before someone took Yuzu away from him, to which Yūya replied that Yuzu wasn't his girlfriend.undefined Sora defeated his third and fourth Duelist's in a Chess and Shogi themed-field respectively, and against his fifth opponent, who he found to be as entertaining as Yūya, Yuzu was much more attentive, urging him to finish the Duel quickly. Yuzu matched his Fusion Summoning chant perfectly, and Sora defeated his opponent. Yuzu pointed out that Sora could have won earlier than that, and Sora explained that he was showing Yuzu Fusion Summoning, as she hadn't seemed to get it previously. When Yuzu claimed to have Fusion Summoning figured out, Sora offered to Duel her, but Masumi showed up again, informing them of the recent attacks in the city and asking them where the masked Duelist was. When things became hostile, Sora suggested that Yuzu could easily beat Masumi, and when challenged himself, claimed that he'd hurt her confidence even more. Masumi's repeated claims that LDS was the strongest attracted the attention of Shun Kurosaki, but Shun was stopped by the masked Duelist, Yūto. Though Sora kept quiet, when Yūto claimed that Yuzu's "Fusion" didn't suit her, Sora was insulted and suggested he show Yūto how great the card was. Yuzu broke them up, but Yūya's arrival teleported Yūto away via Yuzu's bracelet. Sora suggested that they leave after LDS showed up.undefined The next day, Sora had his final opponent, but he had to call Yuzu to get her there, as she was searching for her lost "Fusion".undefined He defeated his opponent with "Death-Toy Scissors Bear" in an opera themed match, and Yuzu congratulated him. Sora suggested that they hurry to Yūya's third match, and they arrived just in time to see him activate Yuzu's "Fusion" and Fusion Summon "Rune-Eyes Pendulum Dragon" against Mieru Hōchun. He congratulated Yūya for doing something so unexpected, and Fusion Summoning without any prior tutelage. The celebrations were interrupted by Mieru hugging Yūya and Yuzu's angry response, scaring even Sora.undefined Sora wanted a party to celebrate his entry, only for Yūya to reply that they could only have one once Yūya had qualified too, much to Sora's distress. As Yūya held him in a friendly headlock, Yuzu left, and Sora wondered if she was getting cake.undefined With Yūya set to Duel Gongenzaka the following day, Sora and the others had to watch the Duel in secret, and Sora was surprised by Gongenzaka's Synchro Summoning and Yūya's use of a Pendulum Monster's effect to Fusion Summon twice, exicting him.undefined

Maiami Championship: Opening
Sora took a passive role in the shenanigans that resulted when Yūya went off by himself, entering the stadium alongside his fellow You Show students. He was surprised to spot Shun among the LDS students, who claimed that he'd been a comrade of theirs from the start, and learned that his first Duel would be against Shun the next day.undefined

Miami Championship: Round 1
Bored by Ayu's Duel against Reira, he went off to look for interesting Duels, but found none, instead, he passed by Shun.undefined Yuzu's rematch against Masumi was next, and Sora watched his protege in satisfaction, especially when she countered Masumi's strategies as he'd taught her. He was furious when he saw that Shun, who had been watching the Duel from the sidelines, had apparently taken his leave before the Duel had ended.undefined

Duel Against Shun
He Dueled against Shun in the third match of the second day. When the Action Field was chosen as "Future City Heartland", he was disappointed that it wasn't the Field where he'd Dueled Yūya, but fine with it since the audience enjoyed it. He tried to get Shun to play along in entertaining the crowd, but Shun simply talked about his experiences and Dueled without mercy. Sora entertained the crowd with his "Furnimal" monsters and his Fusion Summoning, trading blows with Shun evenly until Shun brought out "Raid Raptors - Rise Falcon". Sora was initially dismissive of the Xyz Monster until its powerful effect was revealed, allowing it to gain the ATK of Sora's Special Summoned monsters and attack them all.

The attack delivered a more powerful shockwave to Sora, and he smiled maliciously, deciding to get serious.undefined He brought out "Furnimal Lio" in an attempt to destroy "Rise Falcon", but Shun used Action Cards and Trap Cards to counter him. Being foiled, Sora became frustrated to the point that he had "Furnimal Lio" destroy the environment in a fit of temper, something that was picked up on by his friends. Shun used "Rise Falcon" to destroy "Furnimal Lio" the next turn, despite Sora's best efforts to counter it. Furious, Sora decided to really go all out, bringing out "Death-Toy Chain Sheep" to prevent Shun from saving "Rise Falcon". Though his efforts were successful, Shun activated a "Rank-Up-Magic" card, Ranking-Up "Rise Falcon" into "Raid Raptors - Blaze Falcon". Sora was excited by the new monster, begging Shun to let him enjoy this. Shun replied that Sora would instead feel the agony of defeat and death, using "Blaze Falcon's" effects and more counter cards to destroy "Death-Toy Chain Sheep". Hit into a building, which began to fall, Sora agility escaped the debris. Shun asked if Sora understood what it was like to be hunted now, and Sora revealed the true depths of his depravity, revealing that the attacks his people had made on Shun, and their Duel were all just games to them. With a crazed demeanor, he called out "Death-Toy Mad Chimera", and destroyed "Blaze Falcon" and took control of it. Claiming that he could never be hunted and Shun's group always would be, Sora commented that he'd finish Shun off with his own monster. Calling it ridiculous, as the Resistance always fought prepared for the worst case scenario with the intent to rescue their comrades, Shun Ranked-Up again, calling out "Raid Raptors - Revolution Falcon". Underestimating its 2000 ATK, Sora assumed that Shun was bluffing, but the effect of "Revolution Falcon" finished Sora off, and though Sora obtained an Action Card, a tower fell on Sora before he could use it, ending the Duel in Shun's victory. Refusing to believe that he could lose, especially to "Xyz scum," Sora screamed at Shun to Duel him again, but his frenzied pleas were met with silence and Sora's injuries caused him to pass out.undefined

Sora vs. Yūto
Sora was taken to the hospital for medical attention, but when he woke up, he was approached by Yūto, who wanted to know about Ruri's whereabouts. Sora claimed that he knew nothing about it and that she, like the rest of the hostages, probably became a card. Sora chased Yūto to a park, demanding him to bring Shun to settle the scores, but Yūto pointed out that it was already settled that he lost. Sora insisted that he hasn't lost and provoked Yūto to duel him by saying that he can save Ruri by destroying the Academia. Sora quickly brought out his "Death-Toy Scissors Bear" as usual, and destroyed Yūto's "Phantom Knights Break Sword". However, Yūto Summoned "Dark Rebellion Xyz Dragon" and was about to finish off Sora with its effect, but decided to allow him to stay in the Duel so that he could surrender peacefully. This insulted Sora. Yūya, having arrived and witnessed the Duel, joined the Duel to aid Sora.undefined He managed to Summon "Odd-Eyes Pendulum Dragon", but Yūto countered his plays with his Trap Cards. Sora realized that Yūto had deliberately taken Sora's attack to bring "Xyz Dragon" and held back against him, insulting him even more. Sora claimed that Yūto and Shun were just runaways from the Xyz Dimension, which his allies already conquered and mentioned having been assigned a mission from Academia. He prepared to Summon a powerful Fusion Monster, but because his real identity was revealed, Sora was forced to return to the Fusion Dimension. There he was found unconscious and taken to the doctors to extract his memories as per Leo Akaba's orders.undefined

At Academia, Sora underwent treatment. At one point during his treatment, Sora demanded to return to the Standard Dimension, wanting to get revenge on the Xyz users there. He was unknowingly watched by Serena.undefined

Battle Royal
Sora then directly asked Leo to return to the Standard Dimension. Leo agreed, on the condition that a group of Obelisk Force members would accompany Sora to help him bring Serena back to the Fusion Dimension. Sora was extremely surprised by the fact that Serena resembled Yuzu.undefined Sora later ambushed Shun with three members of the Obelisk Force, dispatching them to Duel against the Knight of Duels while he and Shun Dueled in a nearby ruined building.undefined

Rematch Against Shun
The two began their Duel, with Sora summoning "Edge Imp Tomahawk" in order to damage Shun during his first turn. On his turn, Shun used a combination of "Raid Raptors - Vanishing Lanius" and "Raid Raptors - Fuzzy Lanius" in order to Xyz Summon "Raid Raptors - Force Strix". Sora was amused that "Force Strix only had 100 ATK, and was surprised when Shun used "Force Strix" to get the cards he needed by searching another "Vanishing Lanius" and repeating the combination. Shun Summoned the other copies of "Fuzzy Lanius" and "Vanishing Lanius", allowing "Force Strix" to gain 500 ATK for each of them. Unimpressed, Sora asked about the low ATK of Shun's monsters and if Shun was underestimating him. Shun replied he was always serious while Dueling, even against "worthless opponents". Shun eventually Summoned three copies of "Force Strix", leaving Sora annoyed at how long he planned to prolong that play. Shun mocked Sora for being annoyed by his tactics and told him to get an Action Card. Sora replied he did not need any. Shun then Special Summoned two copies of "Raid Raptors - Singing Lanius", boosting the ATK of the "Force Strixes" to 2100 each, and prepared for a OTK.undefined Most of the Duel took place off-screen, and eventually Sora was left at his last 300 LP while Shun had 2100 LP and both were visibly exhausted. Sora drew "Fusion" and called Shun naïve if he believed his victory was granted. Sora then used the effect of "Furnimal Mouse" to Special Summon two more copies of it from his Deck. He mimicked Yūya's catchphrase with a menacing tone and fused them with "Edge Imp Scissors" in order to Fusion Summon "Death-Toy Scissors Tiger". Sora activated its effect to destroy monsters Shun had up to the number of Fusion Materials used for the Summon of "Tiger", leaving Shun with only one "Force Strix" left. Sora proceeded to mock Shun, since the Xyz Monster was now devoid of most of its ATK and reduced to a mere 100 points, leaving Shun to grind his teeth. The effect of "Tiger" let it gain 300 ATK for to each "Death-Toy" and "Furnimal" monster Sora controlled, which was 2200. This gave it enough power to defeat Shun, with Sora commanding it to "send the Xyz remnant to the grave" with a maniacal expression. Sora was satisfied that he finally got revenge on Shun, but was unaware that Serena was watching.undefined

Duel Against Hikage
Upon seeing Serena, Sora mistook her for Yuzu and told her to back off. When he saw her Academia Duel Disk, he realized who Serena really was and chased her down while she carried an injured Shun with her. He ordered Serena to let him deal with Shun himself, or she would get hurt as well, but Hikage and Tsukikage blocked him. While Hikage Dueled Sora, Tsukikage protected Serena and Shun from the other members of the Obelisk Force. During his Duel, Sora met Yūya and Gongenzaka again, who told him to stop and questioned his actions, which annoyed Sora. He told them to shut up and wait until he defeated Hikage, angering Yūya. Sora eventually defeated Hikage and sealed him into a card. Yūya finally confronted Sora and challenged him to a Duel, which Sora accepted because he disliked the fact that he had a losing record against his old friend. Sora took Yūya to the inside of the Volcano Area so no one could interrupt their Duel.undefined

Rematch Against Yūya
Sora openly promised not to be as soft as he was during his last Duel with Yūya, despite Yūya's protest that Sora's smile back then was genuine. He ridiculed Yūya's belief that they had become friends during their last Duel, dismissing the notion as being too soft. He retorted that Dueling was about fighting, and that winning was more important to him than friendship. He then Fusion Summoned "Death-Toy Scissors Tiger" and used it to destroy all of Yūya's cards on the field and reduce him to 1800 LP. When Yūya chided Sora about the damage Academia caused to Heartland City, he responded that it was necessary to make the worlds one, to which Yūya replied that Academia didn't have that authority. Sora then brought out "Death-Toy Sabre Tiger" and "Death-Toy Scissors Bear" and raised his three monsters' ATK to over 4000 each. He then watched in shock as Yūya Xyz Summoned "The Supreme King Black Dragon - Odd-Eyes Rebellion Dragon", an Xyz Pendulum Monster, and got excited about how Dueling with Yūya was so much fun.However, when Yūya attacked with "Odd-Eyes Rebellion", both Sora and Yūya ended up in a race for an Action Card that disappeared as the Battle Royale timer expired, ending the Duel with no winner. When Yūya realized that realized that Yuzu was nowhere to be seen and began to ask Sora if she had been sealed in a card, instead of answering him, Sora activated the forced return program in his Duel Disk to return to Academia.undefined

Shun vs. Dennis
Sora secretly watched the Duel between Shun and Dennis.undefined When Dennis lost, he left the stadium and rescued him before either the Council or Security could take him into their custody. While hiding from Securities, Sora introduced himself to Dennis and told him to go back to Academia because the Professor has given him the order to retrieve Serena and promised that he will fulfil the mission in his place as Dennis now is in no condition to continue. As he sent Dennis back to Academia, he asked Dennis to told the Professor that he will carry out the mission given to him.undefined

Yūya vs. Shinji
Sora saved Yuzu when she crashed into a building at the end of her Duel, and took her to the Commons area before the Security could get her. He then took Yuzu's helmet and rushed to where Yūya was Duelling Shinji, jumping from one building to another to get his attention. When he noticed him, Sora showed Yūya Yuzu's helmet, telling him that Yuzu is safe, allowing Yūya to fully concentrate in his Duel against Shinji. undefined

Reunion with Yūya
After Yūya defeated Shinji, he escaped the Duel Palace and was able to meet up with Sora. He told Yūya that Yuzu was safe and revealed he had come to the Synchro Dimension to save Yuzu and how he traveled back to the Fusion Dimension and then back to Standard before learning that the Lancers had gone to the Synchro Dimension. Yūya told him that since he sent Dennis back, Academia would know that Yuzu and Serena were in the Synchro Dimension, but Sora insisted Dennis would have reported back in eventually and sending him back separated him for Serena. Still wanting to fight for Academia, but torn because of friendship, Sora asked that Yūya bring Serena to him to trade for Yuzu. However, Yūya refused to abandon Serena either. Yūya told him the Professor probably wouldn't approve of Sora's actions and hoped he would open his eyes soon. A Security officer on a nearby rooftop fired an energy net at Sora, but Yūya pushed him out of the way. Yūya made Sora promise to protect Yuzu and wished him luck as he fled.undefined Sora attempted to look for Yuzu, but she had left the room that he'd left her in and he looked around, noticing the number of Security officers on patrol.undefined

Reunion with Yuzu
Sora later noticed that Yuzu, Frank, Amanda, and Tanner were surrounded by Security. He and Yuzu then Dueled the officers and won. Yuzu introduced Sora has her teacher, and assumed that he had defected from Academia. Sora replied that he hadn't but he was trying to keep Yūya and Yuzu safe from Academia. He tried to convince Yuzu to stay away from the war, but seeing Yuzu's refusal, Sora attempted to send her back to Standard, but Yuzu stopped him. They were interrupted by Tsukikage, who was prepared to Duel Sora in revenge for Sora sealing Hikage, and Sora was prepared for it. Yuzu, however was able to convince Sora to stand down, reminding him of everyone at You Show Duel School who are waiting for them. Sora apologised to Tsukikage for what he had done to his brother, and the latter agreed to let Sora try to rescue Yūya from captivity under Jean-Michel Roger, while suggesting that Yuzu and the kids come underground to hide from Security.undefined

Yūya vs. Crow
Continuing to look for Yūya, Sora eventually noticed that Yūya was Dueling again, this time against Crow Hogan, much to his shock. Sensing that something was wrong, he used his athletic skills to grab onto the wheel of Melissa Claire's helicopter and watched the Duel from the skies. He was surprised when he noticed that Yūya's face reminded him more of Yūto's than it normally did for an instant, his shock increased when Yūya also summoned Yūto's "Dark Rebellion Xyz Dragon," wondering was it really Yūya who was currently Dueling.

Realising that Yūya wasn't himself and something could gone to the worst if it left continue, Sora contemplated to interfere with the Duel and summon his strongest monster to stop "Odd-Eyes Rebellion Dragon", but decided to against it once noticing the Obelisk Force have arrived. Remembering Yūya's determination to protect both Yuzu and Serena, Sora jumped onto Crow's D-Wheel, introducing himself as Yūya's friend and asked for his help to return Yūya to his senses so that he can protect Serena from the Obelisk Force.

Sora & Tsukikage vs. Obelisk Force
When Tsukikage was cornered by the Obelisk Force, Sora decided to save him, finally deciding to directly betraying Academia. Working together with Tsukikage, Sora proceeded to effortlessly overpowered the three Obelisk Forces, defeating them. Sora once again apologized to Tsukikage even though he knew that saving him now won't be enough for what he has done to his brother, but Tsukikage stated that the Fuma clan's ninja way never holds any grudge for a very long time, indirectly telling Sora he forgave him. Sora then split up with Tsukikage, while he went to Serena and Reira's place, Tsukikage went to the underground labor facility to tell the other Lancers about the invasion.undefined

Yūya vs. Barrett
Sora arrived just in time to save Serena from Obelisk Force, knocking them down. Remembering Sora as the Duelist who defeated and injured Shun, Serena at first distrusted him when Sora said he came to save her. When Serena questioned what he was planning, Sora answered that he was their ally, much to Yūya's relief. However, his declaration was heard by Yūri, who has followed him and stated that both Sora and Serena will be apprehended for their treachery. Since Serena was unable to move, Yūri challenged Sora to a Duel, though he mockingly said that it would be an execution since bringing him back to Academia would be hassle. Offended, Sora was ready to Duel Yūri but was interrupted by Yūgo's arrival who challenged Yūri into Duel. More interested in Dueling Yūgo, Yūri has the Obelisk Force to prevent Sora from interfering by having their Antique Gear tightly biting Sora's Duel Disk, making Sora unable to Duel.undefined He helplessly watched as Yūya, Yūgo, Yūri, and the Four Dimension Dragons went on a synchronized rampage again and was horrified when Yuzu appeared and witnessed Yūgo and Yūri teleport away as well as Yūya coming back to his senses. He watched helplessly while struggling vainly to free himself as he screamed at Barrett not to take back Serena.

Yūya vs. Sergey
Sora was eventually freed once the remaining Obelisk Force members retreated out of fear of Sergey and the lack of the presence of Barrett and Yūri. He was surprised to see Yūya take damage just to free Yuzu. Once Yūya was defeated and Tsukikage bore grave injuries from unsuccessfully blocking Sergey's way, Sora took Yuzu's hand and attempted to run away but he also was knocked away by Sergey. He was the least injured from the attack among the trio, but was unable to leave because Reira, who was still traumatised, kept clinging on him.undefined

Commons Rebellion
Gongenzaka, Shingo, and Chojiro found their group with Reira clinging to Sora and forming a trust he rarely shared. Shingo began accusing and taking out his anger at Sora after he saw the serious injuries on Yūya and Tsukikage. He stopped once he saw how Reira clung to Sora, and started listening to Yūya's briefing of what had happened. When Sora decided to go and rescue Yuzu, he gently had Reira let go of him. Tsukikage convinced Sora to let him join the rescue efforts, despite his injuries. Shingo started being suspicious of him again, but Gongenzaka convinced Shingo to trust Sora as he did since Sora was Yūya's friend. Sora and Tsukikage left as Yūya unhappily watched, being unable to go with them himself.undefined

Infiltration of Security's Main Bureau
When Sora and Tsukikage arrived at Security's Main Bureau, the front was guarded by a few officers so they decide to enter a different way.undefined They managed to sneak in but are forced to Duel the Arrest Corps, who are under control as well. While Dueling, they realize that in order to save Yuzu, they must end Security's brainwashing. Sora and Tsukikage proceeded to the control room and destroyed it, releasing all of Security from their mind control. They then went Yuzu's cell and freed her.undefined  But, before the three of them could escape the building, Roger intercepted them. Sora and Tsukikage both Dueled him after Roger baited them into a room, however they were brutally defeated and Roger took Yuzu with him. With his serious injuries, Sora succeeded in reaching out and informing Yūya and all of City through the broadcast system that Roget was intending to take Yuzu back to Academia, effectively warning the Lancers and their allies to hurry and stop Roget and rescue Yuzu. The broadcast cut off abruptly when he got caught up in an explosion Roget set to destroy the building.undefined

Reiji vs. Roget
When Lancers, together with Crow and Jack, gathered in front of the room where Reiji was Dueling against Roget, Sora arrived and revealed he can unlock the system that locking the door. Sora apologised to Yūya for his failure on protecting Serena and Yuzu, promising that he at least can unlock the door for them to save Yuzu. Using the hacking program from his Duel Disk, Sora successfully opened the door and they entered the room with Sora being carried by Gongenzaka. He and Tsukikage explained how they lost to Roget after being lured into a similar room where Roget kept reviving no matter how many times they beat him. However, Reiji revealed that the Roget they had been fighting was only a hologram projection while the real Roget watching from another room above them with Yuzu. With his plan failed, Roget attempted to escape with Yuzu, but this was thwarted by Jack and Crow, allowing Yūya to save Yuzu. Sora and the others were happy watching the reunion between Yūya and Yuzu, but this didn't last long when Roget activated the inter dimensional transport device with intent of destroying the dimension. However, it malfunctioned and instead created a wormhole that sucked Roget himself, later followed by Yuzu, Yūya, Gongenzaka, Shun, and Shingo, while Sora and the others could only watch them disappeared in front of them. He then explained to the confused Crow and Jack that the wormhole is a hole that connects one dimension to another.undefined

Yūya & Sora vs. Captain Solo
When Yūya asked Crow how he got to the Fusion Dimension, Sora told him it's not time for talk since he still Dueling. He was worried when Solo used "Grand Naval Battle" to shoot the speed boat they were in. Sora then joined the Duel, but took the intrusion penalty in the process. He told the Captain it's been awhile and made fun of him for still dressing as a pirate. He got mad when Solo told him that Serena came back, but told Solo that they were taking Serena back and defeating him. When Shingo tried to tell Sora about the effect of "Captain Lock", Sora already knew how to counter it with his Extra Deck. He Fusion Summoned "Death-Toy Piton Kraken", which causes the effect of "Lock" to activate and destroy itself. However, Solo brought "Lock" back with its effects negated and strengthened its ATK with "Deadman Pirates". Yūya then used "Entermate Big Support" to equip "Entermate Sword Fish" to "Kraken", increasing its ATK. With the effect of "Kraken" letting it attack twice per turn, Sora used it to destroy "Lock" and attack Solo directly. When Yūya thought there was a reason why Serena kidnapped Yuzu, Sora told him that the Professor had someone who could control people's hearts and minds.undefined

Heading towards Academia
Yūya asked him why the Professor wanted Yuzu and her counterparts, and Sora suggested that they might be connected to the ARC Area Project.undefined Sora learned that Reiji went to Academia three years ago and asked Yūya's father for help. He also learned that Reiji found out about Revival Zero, another part of the Professor's plan involving Serena and Yūri, and may include Yūya as well. He and other Lancers were told by Reiji to believe in their friends strength and fight to the very end. After arriving on the island, Sora told Shingo that the mountain is closer to the Professor's lab and prepared to climb it.undefined After climbing up the mountain, they were surrounded by Academia students before utilizing their plan to split into two groups with Sora, Reiji, and Reira continuing to the lab while Yūya's group Dueled the students.undefined

Yūri vs. Asuka
Along the way they met up with Yūshō and Asuka but were confronted by Yūri.undefined When Asuka pushed Yūri to the wall, Sora activated the fence to trap him in. However, after pushing Reira out of the way he got trapped between the fence, which disabled his Duel Disk. He watched Asuka try to seal Yūri attacks but was surprised destroyed his own card. He was mad when Yūri claimed "Antique Gear Reactor Dragon", a Release Monster, was a trump card of the Honor Student Deck. He got worried when Asuka lost most of her LP in one turn but happy when took control of "Reactor Dragon". He was surprised when Yūri used "Super Fusion" and watched him defeat Asuka, sealing her into a card. He then wondered why the fence was deactivating and learned Yūri had control over them as well.undefined

Duel against Yūri
He Dueled Yūri and used "Death-Toy Fusion" to Fusion Summon "Death-Toy Mad Chimera". He destroyed "Antique Gear Hydra" and used the effect of "Chimera" to Special Summon "Hydra" on his field. "Chimera's" ATK increased by this effect and Sora attacked Yūri directly with "Hydra". He is forced to return "Hydra" when Yūri used "Antique Gear Inspection" and was defeated by "Antique Gear Ultimate Golem". He was about to be sealed into a card until Yūgo and Edo arrived.undefined

Yūgo vs. Yūri
He told Edo that he heard that Yūya got him to join him. He then commented about how there are two other people who look like Yūya. When Yūgo and Yūri enter a synchronized awakening again, Sora remembered how it was the same as last time.undefined When the Four Dimension Dragons resonated again, Sora watched "Clear Wing Synchro Dragon" and "Starve Venom Fusion Dragon" resonate.undefined When Edo returned, Sora told him to stop the Duel. While watching the Duel, Sora remembered how Edo graduated from Academia and was appointed Commander-in-Chief and that he never liked him. He watched Edo free Yūgo from his awakening and tried to join the Duel when Yūri defeated Edo and Kaito, but was to hurt.undefined He was surprised when Yūri defeated Yūgo undefined and watched Yūri absorb him.undefined

Yūya vs. Yūri
He and Edo then went to go find Yūya and the others, noticing the space around them started to distorting. They then arrived at the inner chambers and were caught in the Isolation Dome, separated from ARC-V. Learning that Yūri sealed Yūshō into a card and seeing Yūya struggling, Sora then prepared to Duel Yūri with Reiji, Reira, and Edo to protect Yūya, but were sent flying by Yūri. He told Yūya he believed him after Reiji revived his broken spirit from discarding "Smile World". He saw Yūto and Yūgo supporting Yūya to defeat Yūri and noted that he will win once Yūya used the effect of "Dark Rebellion Xyz Dragon". He watched Yūya defeat Yūri and told the latter that Yūya won't absorb him since Yūto and Yūgo felt the same way and lent their power to him. However, Sora was shocked when Zarc revealed to have controlled Yūya and summoned "Astrograph Magician" to fuse with the Four Heavenly Dragons. He then ran outside with Reiji, Reira, and Edo to find the world floating in pieces and saw the revived Supreme King Dragon Zarc.undefined

Sora & Edo vs. Zarc
While Reiji and Reira went to look for Leo, Sora and Edo decided to confront Zarc. When Edo was horrified to see there result of ARC Area Project they had helped to fulfil, Edo asked for Sora's assistance to atone for what they did. Sora replied by saying that he refused to do so unless Edo lend him his help, offering one of his candies. At the town, Sora and Edo challenged Zarc to a Duel. Seeing Zarc's demonic form yet still resembles Yūya, Sora questioned Zarc what happened to Yūya and did he controlled him, to which Zarc replied that Yūya no longer exist as he was his reincarnation who have helped his revival. When Zarc performed Pendulum Summon, Sora took this as a sign that Yūya's conscience is still exist deep inside Zarc and resolved to return Yūya. During his turn, Sora summoned "Death-Toy Mad Chimera" while trying to reach out for Yūya by showing him his Pendulum Pendant that he have picked up and reminded him of their first Duel, calling him "Teacher" like the first time they met. When there was no response, Sora tearfully ended his turn, assisting Edo by activating his trap card "Death-Toy Mad Parade" to destroy all of Zarc's card. Sora and Edo started to get their hopes up from this, but this didn't last long as they have inadvertently helped Zarc to summon "Astrograph Magician" to not only revive all of his destroyed monsters but also performed Integration Summon, summoning "Supreme King Dragon Zarc" whose effect destroyed both Sora and Edo's monsters and inflicted damage equal to their combined ATKs, defeating Sora and Edo at once. Before losing his consciousness, Sora begged Shun and Kaito to save Yūya in their place, giving Yūya's Pendulum Pendant to Shun.undefined

Shun & Kaito vs. Zarc
When Zarc used the effect of "Supreme King Servant Dragon Dark Rebellion" to protect "Zarc" from "Rise Falcon's" attack, Sora noted that "Zarc" can't be attacked because its the integration of all Summoning methods. He and Edo were then found by Gongenzaka and Shingo and they told them how Yūya became Supreme King Dragon Zarc, including how they were trying to regain Yūya's heart through Dueling. He was surprised when Zarc defeated Shun and Kaito.undefined

Gongenzaka & Jack vs. Zarc
He was also surprised to learn to Crow sealed into a card, Zarc's negative reaction to Entertainment Dueling, and the effect of "Supreme King Servant Dragon Clear Wing" equipped with "Supreme King Violent Spirit" to destroy all of Gongenzaka's monsters. When Jack was going up the highway, Sora noted that he had no hesitation. When Jack attacked "Clear Wing", Sora and Edo still remembered that Zarc could use the effects of "Zero" and "infinity" to reduce effect damage to zero and increase his LP by the damage would've taken. Sora was caught off-guard upon seeing Crow arrived, having been unsealed from his card.undefined

Shingo and Crow vs. Zarc
He was also surprised when Crow negated the effect of "Zero" and dealt damage to Zarc. When Zarc forced "Assault Black Feather - Chidori the Light Rain" to attack "Zarc", Sora and Edo wondered why. He was also surprised when he thought Shingo defeated Zarc with "Abyss Script - Abyss Entertainment" and when Zarc used the monsters he destroyed to protect "Zarc". Sora and Edo were surprised when Leo Akaba joined the Duel and watched Zarc defeat Shingo and Crow, sending them crashing onto a building's roof.undefined

Zarc vs Reiji, Ray & Reira
He and Edo were happy when Reiji managed to dealt damage to Zarc. Sora was surprised when he thought "Zarc" killed Reiji. He and Edo were happy when Ray turned all of Zarc's Fusion Monsters into Normal Monsters with their effects negated.undefined

Yūya vs Shun
Following the battle against Zarc, Sora met with Yūya, who just arrived in the Fusion Dimension, and ran to take him to Shun, who was attempting to enter Leo's chambers as Asuka tried to stop him. Yūya challenged Shun to a Duel, but Shun denied his challenge. Sora realized that Shun wouldn't listen to them about Ray, and he asked Asuka to let Shun in. Sora watched as Leo observed the floating specter of what he predicted would become Yuzu, and as Leo admitted his fault in destroying the lives of Ray's fragments. Sora and Asuka watched Yūya and Shun's Duel, and Sora noted that Shun and Yūya were going all-out from the start as they countered one another with Action Cards. He was shocked to see that Shun had continued to evolve when he Ranked-Up "Revolution Falcon" into the Rank 12 "Raid Raptors - Final Fortress Falcon". Yūya eventually won the Duel, but as Yūya and Shun declared that there was hope for Yuzu, Yūto and Ruri, Jack Atlas then declared that Yūya couldn't save them in his current state.undefined

Yūya vs. Jack
When Sora asked Yūya was he losing his backbone and wonder why, he learned from Jack that Yūya was afraid of using the four dragons because he might integrate with them again. When Jack and Reiji both agreed that Yūya should use the four dragons, Sora learned that Shun and Dennis' Duels with Yūya didn't make Reira react and was surprised when Dimension Highway activated throughout the Four Dimensions. He then saw Crow bringing Yūya his D-Wheel and Riding Dueling outfit and watch the Duel with Crow, Shun, and Asuka. He was worried when Yūya was pushed into a corner.

Abilities
Sora can make cute expressions which causes people to do something for him, etc. In Episode 15, Sora showed some good senses, able to note that someone was around and staring at him. Sora can also fight by using his Duel Disk as a weapon. Despite his small size, Sora demonstrates an incredible degree of athleticism, being able to knock out three boys much larger than himself using only a lollipop stick, and later able to knock out two adults with only a single blow each. He also displays incredible jumping ability to quickly snatch Action Cards during Duels.

Deck
Sora uses a "Furnimal"/"Edge Imp" Deck focused on Fusion Summon tactics, with "Toypot" assisting in swarming. As Fusion Summoning requires a large amount of specific cards, Sora uses cards such as "Edge Imp Saw" and "Fusion Conscription" to acquire them easier. He also uses cards such as "Death-Toy Factory" and "Death-Toy Fusion" which give him easier access to his "Death-Toy" monsters. He also uses effects to treat his monsters as "Death-Toy" monsters, in order to use his "Death-Toy Mad Chimera" easier.

Although Sora prefers to Fusion Summon "Death-Toy Scissors Bear" to easily acquire ATK power, he is also flexible and can Fusion Summon different monsters shall the need arise, such as "Death-Toy Wheel Saw Lio" to destroy difficult monsters, "Death-Toy Chain Sheep" to disable the opponent from activating cards, and "Death-Toy Scissors Tiger" to wipe the opponent's field clear and deal the finishing blow. He also often uses "Edge Imp Tomahawk" as a way to damage his opponent during his first turn.
