Sora Perse Sora Perse , known as Sora Shiunin ( " Shiun ' in Sora " ) in the Japanese version , is a character in the " Yu - Gi - Oh ! ARC - V " anime . Interested in the Pendulum Summon Yuya Sakaki created , this mysterious boy decides to become his apprentice . During his first Duel against Shay Obsidian , Sora is revealed to be a soldier of Duel Academy , an agent send from the Fusion Dimension to infiltrate LID . As a soldier of Duel Academy , he swears loyalty to Leo Akaba and his plan to " unite the dimensions " despite his friendships with Yuya and Zuzu Boyle . With encouragement from Yuya and Zuzu , Sora eventually realized he was hurting people and reluctantly abandoned his old ways . Since then , he has formally turned his back on Duel Academy and becomes an ally and later member of the Lancers , working to keep Celina and his first friends Zuzu and Yuya safe . Design . Appearance . Sora is a short , young boy with light cyan hair , that is tied up and spiked out . He wears a blue jacket that bears some resemblance to Duel Academy ' s Obelisk 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 Yoko Sakaki who gave him Yuya ' s pancakes and Skip Boyle who changed the field that Sora and Yuya 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 Card s during Duels . Personality . Sora is shown to be a huge fan of Yuya , to the extent of obsession . This is shown when he constantly follows Yuya around , wanting to see Pendulum Summon ing first hand ( in the dub , Sora also calls Yuya " Coach Y " ) . At first Yuya declines , causing Sora to spy on Yuya 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 Yuya , who only agrees to Duel with him if Sora stops following him around . Sora is also extremely childish and persists until he gets his way . Early on in the show 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 Institute of Dueling . Sora also shows exceptional knowledge of " Duel Monsters " for his age , including the different styles of Summon ing 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 Shay 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 Monster s and violently attacking his opponent , while slowly revealing more of his horrifying nature as he explains how much he and his people enjoyed " hunting " Shay and his comrades , simply because it is a " fun hunting game " , while showing some disgust towards Shay , calling him " Xyz Scum . " He is infuriated by his loss against Shay , showing he has a superiority complex and a huge ego . His pride can be seen earlier : he derides LID Fusion Summons and believes that Zuzu would be the clear victor in a match against them if she uses the techniques that he taught her , and after Yuto told Zuzu that " Polymerization " did not suit her , Sora was offended enough to challenge Yuto 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 Duel Academy ' 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 . With encouragement from Yuya and Zuzu , Sora realized he was hurting people and reluctantly abandoned his old ways . He is also shown to be obsessed with sweet food items 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 . Abilities . Due to his training at Duel Academy , Sora is well - versed in the art of fighting . By simply throwing his lollipop stick , he can knock multiple people out at once . He is also capable incapacitating two ( presumably ) well - trained individuals while injured . Sora also possesses incredible athletic abilities , as he was able to leap across rooftops while keeping up with Duel Runner s ( even jumping several feet in the air at one point ) . In addition Sora has incredible endurance ; and he is able to hang onto a helicopter ' s wheels without much difficulty . Etymology . His family name , Shiun ' in 「 」 , translates roughly to " violet cloud school / temple / house " . Also , " Shiun " , or purple cloud , is the one that rides on at a time of a person ' s death . The kanji for his first name , Sora , 「 」 , is gender neutral , but is usually read as ' Motoyoshi ' 「 」 for males . His dub surname , Perse , is a color that is grayish blue or purple . Perse is also a name for a private school in Cambridge , England . Both could be a reference to Duel Academy and their preference for Fusion Monsters , which have a purple card border . Biography . History . Sora attended Duel Academy 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 . One day , when walking pass Aster Phoenix , he was asked by Aster to join him when he graduate . However , Sora refused since he wasn ' t one for the military and could do everything by himself . Sora was the top of the elite class at Duel Academy , and he was sent to the Standard Dimension with a special mission . Pre - Arc League Championship . When Yuya and his friends went to the Leo Institute of Dueling , Sora passed Yuya as he was looking at the school ' s curriculum . He stopped for a moment to look at Yuya before carrying on down the corridor . He later watched Yuya ' s Duel with Sylvio Sawatari , amazed by how the latter managed to perform a Pendulum Summon . He continued to watch the Duel and was excited when Yuya managed to retrieve his " Timegazer Magician " and " Stargazer Magician " . After the Duel finished , Sylvio attempted to get his friends to assault Yuya and his friends , but was stopped by Sora who knocked them unconscious with his lollipop stick . He then introduced himself to Yuya and declared himself Yuya ' s apprentice ( in the dub , Sora called Yuya his " Duel Guru " ) , shocking him and his friends in the process . The next day , he followed Yuya home to his house , gaining entry by telling Yoko Sakaki that he was Yuya ' s apprentice . Yuya 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 Yuya ' s " sister ' s " pancakes were delicious . Yoko ' 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 Yuya ' s sister . Yoko , appreciating the praise , gave him Yuya ' s pancakes as well . After that incident , Sora followed Yuya to school as Yuya was explaining what Sora was doing to Zuzu , stating that wherever his teacher went , Sora would follow . Yuya reminded him that he never made Sora his apprentice , but Sora begged him to make him his apprentice , expressing an admiration for Yuya ' s Pendulum Summoning . Yuya explained that one needed Pendulum Cards to Pendulum Summon , so Sora begged Yuya to show him . He tried his flattery tactics again by asking Zuzu to convince Yuya to show him a Pendulum Summon as he thought she was Yuya ' s girlfriend , however , this led to both denying it and Yuya accidentally insulting Zuzu , and Yuya being swatted by Zuzu ' s fan , to Sora ' s surprise and concern . He spied on Yuya in class through binoculars , wondering why he was making such a serious face , and continually harassed Yuya throughout the day . When Yuya went to the You Show Duel School , Sora was there as well , having claimed again to be Yuya ' s apprentice . He requested to Duel Yuya , who refused ( and thus Sora gained the sympathies of everyone present ) until Skip Boyle convinced him otherwise . Yuya 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 , Yuya would take him on as an apprentice . The Duel began , but Sora was displeased by the choice of the " Wildest West " Field Spell Card , and he said it was boring , then requested a more fun one , so Skip changed it to " Sweets Island " . Sora began to swarm the field with his " Toy Vendor , " but his attacks were stopped by Yuya , who had been collecting Action Card s while " accidentally " crashing into the scenery . Sora attempted to grab an Action Card himself , only for Yuya to snatch it away . Yuya 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 Summon ing his " Frightfur Bear " . He took out Yuya ' s " Performapal Hip Hippo " to reduce his mobility and equip ped it to his " Frightfur Bear " to power it up . When Yuya tried to counterattack , Sora used two copies of " Punch - in - the - Box " to bypass the effect of " Timegazer Magician " , weakening " Odd - Eyes . " Sora then equipped his " Frightfur Bear " with " Toy Parade " to allow it to attack multiple times , a combo that would allow him to win the Duel . Yuya attempted to grab an Action Card , but Sora revealed previously unseen agility and snagged it himself . He then used it to prevent Yuya ' s own Trap Card from affecting " Frightfur Bear " and destroyed " Odd - Eyes . " With Yuya despondent and " Odd - Eyes " destroyed , Sora attempted to equip the Dragon to " Frightfur Bear , " but to his surprise , he was unable to . Yuya 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 Yuya weakened " Frightfur Bear " on his next turn with " Performapal Sword Fish " and " Performapal 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 Yuya ' s friend instead , calling Yuya by his first name ( much to Yuya ' s anger ) and enrolled into You Show Duel School . Yuya attempted to find where Sora had learned to Fusion Summon , seeing as he hadn ' t been to LID , but Sora evasively replied that it was normal where he came from , irritating Yuya once again . He continued attending You Show Duel School , and when LID Chairwoman Henrietta Akaba arrived , claiming that Yuya had attacked Sylvio 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 Gong that he wasn ' t technically a You Show student . He wanted to Duel first , but Yuya instead went first , facing Xyz user Dipper . During the Duel , Sora protested that it wasn ' t very entertaining , receiving swift rebuke from Yuya in response . He also explained about Xyz Monster s and Rank s to Allie , Frederick and Tate . After Yuya defeated Dipper , Zuzu was up next , facing Fusion user Julia Krystal . Unfortunately , Zuzu lost the Duel , and Gong encouraged Sora to win the third Duel against Synchro user Kit Blade . Claiming that the Duel disinterested him , Sora instead allowed Gong to Duel Kit , much to Gong ' s happiness . 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 - Gong " didn ' t have a chance to win , until Gong ' s use of his " Superheavy Samurai " monsters surpassed Sora ' s expectations and caused him to drop his lollipop in shock . Gong ended the Duel in a DRAW , so Henrietta proposed a tiebreaker between Yuya and Julia . A mysterious grey - haired Duelist revealed himself , stating that he would put an end to this . He used " D / D " monsters against Yuya , Sora noting that the title stood for " Different Dimension . " He was shocked when Declan performed a Fusion Summon to bring out " D / D / D Flame King Genghis " . Despite Declan being set up to take 4000 damage from his own cards , Sora wasn ' t convinced that Declan was overconfident enough to take the risk and he was proven correct . Declan later set himself up to take 3000 damage , enough to wipe him out , but again , Sora knew that Declan would evade the damage . But even Sora was shocked when Declan unveiled his own Pendulum Monsters and gained an edge in the Duel . Fortunately , a call regarding an LID teacher reached the ears of Declan , who revealed his name and forfeited the Duel before departing . Sora was impressed at Declan ' s Pendulum Summoning , and as Skip reassured the students that they ' d saved their Duel School , Sora pointed out that only Yuya had contributed to doing so . Tate , Allie and Frederick 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 . Zuzu later found him trying to get into LID to Duel Declan , 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 . Zuzu took Sora to the warehouse where Yuya had apparently attacked Sylvio , and begged him to teach her to Fusion Summon . Sora was quite bewildered , asking if this had been because Zuzu lost to Julia . Sora wasn ' t sure if it was okay to do so , but he eventually gave Zuzu a " Polymerization " 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 . Zuzu then spoke up , remembering the masked Duelist from before , much to Sora ' s surprise . Zuzu explained that the Duelist had attacked Sylvio , 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 Julia 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 . Zuzu and Julia argued over who was talking to the masked Duelist , and Zuzu ' s bracelet activated , causing him to vanish while they weren ' t looking . An instant later , Yuya arrived , having been looking for Zuzu and he was surprised to see everyone else there . When Julia interrogated Yuya , 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 Yuya that he was giving Zuzu Fusion Summoning lessons . Yuya revealed that his next four Duels had been set up to allow him to qualify for the Junior Arc League 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 . After eating breakfast at Yuya ' s house again and conversing with him , Sora set off to qualify , accompanied by Zuzu , and he defeated a sumo wrestler Duelist with his " Frightfur Bear " . He defeated his second Duelist , a performer Duelist , but noticed that Zuzu was still preoccupied and not paying attention to his Dueling . He Dueled Zuzu 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 Zuzu 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 Zuzu warned him about the Duelist ' s ability to inflict damage outside of an Action Duel . Yuya arrived , prompting Zuzu ' s bracelet to glow again and warp the eavesdropping masked Duelist away . Having dinner at Yuya ' s house , in response to being cautioned for his carefree attitude towards his opponents , Sora told him to be careful before someone took Zuzu away from him , to which Yuya replied that Zuzu wasn ' t his girlfriend . Sora defeated his third and fourth Duelist ' s in a Chess and Shogi themed - field respectively , and against his fifth opponent , whose Kabuki style Sora found to be as entertaining as Yuya , Zuzu was much more attentive , urging him to finish the Duel quickly . Zuzu matched his Fusion Summoning chant perfectly , and Sora defeated his opponent . Zuzu pointed out that Sora could have won earlier than that , and Sora explained that he was showing Zuzu Fusion Summoning , as she hadn ' t seemed to get it previously . When Zuzu claimed to have Fusion Summoning figured out , Sora offered to Duel her , but Julia 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 Zuzu could easily beat Julia , and when challenged himself , claimed that he ' d hurt her confidence even more . Julia ' s repeated claims that LID was the strongest attracted the attention of Shay , but Shay was stopped by the masked Duelist , Yuto . Though Sora kept quiet , when Yuto claimed that Zuzu ' s " Polymerization " didn ' t suit her , Sora was insulted and suggested he show Yuto how great the card was . Zuzu broke them up , but Yuya ' s arrival teleported Yuto away via Zuzu ' s bracelet . Sora suggested that they leave after LID showed up . The next day , Sora had his final opponent , but he had to call Zuzu to get her there , as she was searching for her lost " Polymerization . " He defeated his opponent with " Frightfur Bear " in an opera - themed match , and Zuzu congratulated him . Sora suggested that they hurry to Yuya ' s third match , and they arrived just in time to see him activate Zuzu ' s " Polymerization " and Fusion Summon " Rune - Eyes Pendulum Dragon " against Aura Sentia . He congratulated Yuya for doing something so unexpected , and Fusion Summoning without any prior tutelage . The celebrations were interrupted by Aura hugging Yuya and Zuzu ' s angry response , scaring even Sora . Sora wanted a party to celebrate his entry , only for Yuya to reply that they could only have one once Yuya had qualified too , much to Sora ' s distress . As Yuya held him in a friendly headlock , Zuzu left , and Sora wondered if she was getting cake . With Yuya set to Duel Gong the following day , Sora and the others had to watch the Duel in secret , and Sora was surprised by Gong ' s Synchro Summon ing and Yuya ' s use of a Pendulum Monster ' s effect to Fusion Summon twice , exciting him . Arc League Championship . Sora took a passive role in the shenanigans that resulted when Yuya went off by himself , entering the stadium alongside his fellow You Show students . He was surprised to spot Shay among the LID students , who claimed that he ' d been a comrade of theirs from the start , and learned that his first Duel would be against Shay the next day . Bored by Allie ' s Duel against Riley Akaba , he went off to look for interesting Duels , but found none , instead , he passed by Shay . Zuzu ' s rematch against Julia was next , and Sora watched his protege in satisfaction , especially when she countered Julia ' s strategies as he ' d taught her . He was furious when he saw that Shay , who had been watching the Duel from the sidelines , had apparently taken his leave before the Duel had ended . He Dueled against Shay in the third match of the second day . When the Action Field was chosen as " Neo Heartland City " , he was disappointed that it wasn ' t the Field where he ' d Dueled Yuya , but fine with it since the audience enjoyed it . He tried to get Shay to play along in entertaining the crowd , but Shay simply talked about his experiences and Dueled without mercy . Sora entertained the crowd with his " Fluffal " monsters and his Fusion Summoning , trading blows with Shay evenly until Shay brought out " Raidraptor - 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 Summon ed monsters and attack them all . The attack delivered a more powerful shockwave to Sora , and he smiled maliciously , deciding to get serious . He brought out " Frightfur Leo " in an attempt to destroy " Rise Falcon " , but Shay used Action Card s and Trap Card s to counter him . Being foiled , Sora became frustrated to the point that he had " Frightfur Leo " destroy the environment in a fit of temper , something that was picked up on by his friends . Shay used " Rise Falcon " to destroy " Frightfur Leo " the next turn , despite Sora ' s best efforts to counter it . Furious , Sora decided to really go all - out , bringing out " Frightfur Sheep " to prevent Shay from saving " Rise Falcon " . Though his efforts were successful , Shay activated a " Rank - Up - Magic " card , Ranking - Up " Rise Falcon " into " Raidraptor - Blaze Falcon " . Sora was excited by the new monster , begging Shay to let him enjoy this . Shay replied that Sora would instead feel the agony of defeat and death and used the effects of " Blaze Falcon " and more counter cards to destroy " Frightfur Sheep " . Hit into a building , which began to fall , Sora ' s agility allowed him to escape the debris . Shay 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 Shay , and their Duels were all just games to them . With a crazed demeanor , he called out " Frightfur Chimera " , destroyed " Blaze Falcon " , and took control of it . Claiming that he could never be hunted and Shay ' s group always would be , Sora commented that he ' d finish Shay 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 , Shay Ranked - Up again , calling out " Raidraptor - Revolution Falcon " . Underestimating its 2000 ATK , Sora assumed that Shay 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 Shay ' s victory . Refusing to believe that he could lose , especially to " Xyz scum , " Sora screamed at Shay to Duel him again , but his frenzied pleas were met with silence , and Sora ' s injuries caused him to pass out . Sora was taken to the hospital for medical attention , but when he woke up , he left the hospital and found Yuto , who wanted to know about Lulu ' 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 Yuto to a park , demanding him to bring Shay to settle the scores , but Yuto pointed out that it was already settled that he lost and began a Duel against Sora . Sora quickly brought out his " Frightfur Bear " as usual , and destroyed Yuto ' s " The Phantom Knights of Break Sword " . However , Yuto Xyz Summon ed " 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 . Sora was infuriated and insulted by the show of mercy , which he perceived as intentional humiliation . Yuya , having arrived and witnessed the Duel , joined the Duel to aid Sora . He managed to Summon " Odd - Eyes Pendulum Dragon " , but Yuto countered his plays with his Trap Card s . Sora realized that Yuto had deliberately taken Sora ' s attack to bring out " Xyz Dragon " and held back against him , insulting him even more . Sora claimed that Yuto and Shay were just runaways from the Xyz Dimension , which his allies already conquered and mentioned having been assigned a mission from Duel Academy . 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 . At Duel Academy , 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 overheard by Celina . 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 Celina back to the Fusion Dimension . Sora was extremely surprised by the fact that Celina resembled Zuzu . Sora later ambushed Shay with three members of the Obelisk Force , dispatching them to Duel against the Knights of the Duel Disks while he and Shay Dueled in a nearby ruined building . The two began their Duel , with Sora Summoning " Edge Imp Tomahawk " in order to damage Shay during his first turn . On his turn , Shay used a combination of " Raidraptor - Vanishing Lanius " and " Raidraptor - Fuzzy Lanius " in order to Xyz Summon " Raidraptor - Force Strix " . Sora was amused that " Force Strix only had 100 ATK , and was surprised when Shay used " Force Strix " to get the cards he needed by searching another " Vanishing Lanius " and repeating the combination . Shay 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 Shay ' s monsters and if Shay was underestimating him . Shay replied he was always serious while Dueling , even against " worthless opponents " . Shay eventually Summoned three copies of " Force Strix " , leaving Sora annoyed at how long he planned to prolong that play . Shay mocked Sora for being annoyed by his tactics and told him to get an Action Card . Sora replied he did not need any . Shay then Special Summoned two copies of " Raidraptor - Singing Lanius " , boosting the ATK of the " Force Strixes " to 2100 each , and prepared for a One Turn Kill . Sora survived Shay ' s assault and the Duel was prolonged most of the night . Finally , Sora drew " Polymerization " and called Shay naive if he believed his victory was granted . Sora then used the effect of " Fluffal Mouse " to Special Summon two more copies of it from his Deck . He mimicked Yuya ' s catchphrase with a menacing tone and fused them with " Edge Imp Sabres " in order to Fusion Summon " Frightfur Tiger " . Sora activated its effect to destroy monsters Shay had up to the number of Fusion Materials used for the Summon of " Tiger " , leaving Shay with only one " Force Strix " left . Sora proceeded to mock Shay , since the Xyz Monster was now devoid of most of its ATK and reduced to a mere 100 points , leaving Shay to grind his teeth . The effect of " Tiger " let it gain 300 ATK for to each " Frightfur " and " Fluffal " monster Sora controlled , which was 2200 . This gave it enough power to defeat Shay , 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 Shay , but was unaware that Celina was watching . Upon seeing Celina , Sora mistook her for Zuzu and told her to back off . When he saw her Academy Duel Disk , Sora realized who Celina really was and chased her down while she carried an injured Shay with her . He ordered Celina to let him deal with Shay himself , or she would get hurt as well , but Sun Shadow and Moon Shadow blocked him . While Sun Shadow Dueled Sora , Moon Shadow protected Celina and Shay from the three remaining members of the Obelisk Force . During his Duel , Sora met Yuya and Gong again , who told him to stop and questioned his actions , which annoyed Sora . He told them to shut up and wait until he defeated Sun Shadow , angering Yuya . Sora eventually defeated Sun Shadow and sealed him into a card . Yuya 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 Yuya to the inside of the Volcano Area so no one could interrupt their Duel . Sora openly promised not to be as soft as he was during his last Duel with Yuya , despite Yuya ' s protest that Sora ' s smile back then was genuine . He ridiculed Yuya ' 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 " Frightfur Tiger " and used it to destroy all of Yuya ' s cards on the field and reduce him to 1800 LP . When Yuya chided Sora about the damage Duel Academy caused to Heartland City , he responded that it was necessary to make the worlds one , to which Yuya replied that Duel Academy didn ' t have that authority . Sora then brought out " Frightfur Sabre - Tooth " and " Frightfur Bear " and raised his three monsters ' ATK to over 4000 each . He then watched in shock as Yuya Xyz Summoned " Odd - Eyes Rebellion Dragon " , an Xyz Pendulum Monster , and got excited about how Dueling with Yuya was so much fun . However , when Yuya attacked with " Odd - Eyes Rebellion " , both Sora and Yuya ended up in a race for an Action Card that disappeared as the Battle Royal timer expired , ending the Duel with no winner . When Yuya realized that Zuzu 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 Duel Academy . Friendship Cup . Sora returned to Duel Academy and searched for Zuzu , believing that Yuri had captured her . He found no trace of her , but learned by eavesdropping on the Professor that he needed both Zuzu and Celina for his plans . Sora returned to the Standard and learned that Declan had formed the Lancers and traveled to the Synchro Dimension . Seeing that both Yuya and Celina were among them , he traveled to the Synchro Dimension himself . During Shay ' s second Duel with Dennis McField during the Friendship Cup , Sora silently watched the Duel from a corridor leading to the stadium . After Dennis lost the Duel , Sora left . Friendship Cup Finals . When the envoys of the High Council clashed with Sector Security over the custody of Dennis , Sora intervened and rescued Dennis , taking him to an alleyway . He explained to Dennis that he was attempting to capture Celina as per the orders of the Professor , and sent Dennis back to Duel Academy to recover from his injuries . After Zuzu lost her Duel to Sergey Volkov and was thrown into a building , Sora rescued her before Sector Security reached her . He carried her to a room and left her to rest . After that , Sora ran to show Yuya that Zuzu was okay by showing him her helmet during his own Duel with Shinji Weber . He had to traverse several rooftops until he was at a point where Yuya could see him . After Yuya defeated Shinji , he escaped the Duel Palace and was able to meet up with Sora . Sora told Yuya that Zuzu was safe and revealed he had come to the Synchro Dimension to save Zuzu and how he traveled back to the Fusion Dimension , then back to Standard before learning that the Lancers had gone to the Synchro Dimension . Yuya told him that since he sent Dennis back , Duel Academy would know that Zuzu and Celina were in the Synchro Dimension , but Sora insisted Dennis would have reported back in eventually and sending him back separated him for Celina . Still wanting to fight for Duel Academy , but torn because of his friendship with Yuya and Zuzu , Sora asked that Yuya bring Celina to him to trade for Zuzu . Yuya refused to abandon Celina either , and told Sora that the Professor probably wouldn ' t approve of Sora ' s actions and hoped he would open his eyes soon . A Sector Security officer on a nearby rooftop fired an energy net at Sora , but Yuya pushed him out of the way and was captured instead . Yuya made Sora promise to protect Zuzu and wished him luck as he fled . Sora attempted to look for Zuzu , evading Sector Security on the way , but she had left the room that he ' d left her in and he looked around , noticing the number of Sector Security officers on patrol and wondering if it was because they were looking for Zuzu since she ' d lost in the tournament . Sora later noticed that Zuzu , Frank , Tarren and Amanda were surrounded by Sector Security . He and Zuzu then Dueled the officers and won . Zuzu introduced Sora has her teacher , and assumed that he had defected from Duel Academy . Sora replied that he hadn ' t but he was trying to keep Yuya and Zuzu safe from Duel Academy . They were interrupted by Moon Shadow , who was prepared to Duel Sora in revenge for Sora sealing Sun Shadow . Zuzu was able to convince both of them to stand down , and Moon Shadow agreed to let Sora try to rescue Yuya from captivity under Jean - Michel Roget , while suggesting that Zuzu and the kids come underground to hide from Sector Security . Continuing to look for Yuya , Sora eventually noticed that Yuya was Dueling again , this time against Crow Hogan . He used his athletic skills to grab onto the wheel of Melissa Trail ' s helicopter and he watched the Duel from the skies . He was surprised when he noticed that Yuya ' s face reminded him more of Yuto ' s than it normally did for an instant . When Yuya Xyz Summoned Yuto ' s " Dark Rebellion Xyz Dragon " , Sora even wondered whether or not it was Yuya who was Dueling . Sora continued to monitor the situation with Yuya and became concerned about his friend when the Duel lane changed to leave a considerably wide gap mid - air . Just as when he decided to join the Duel and stop Yuya to save Crow , he spotted the Obelisk Force from the sky . Remembering Yuya ' s promise that he could not abandon Celina for Zuzu , Sora decided to protect Celina and unofficially defected from Duel Academy . He let go of the helicopter wheel and landed on Crow ' s Blackbird . He informed Crow that Yuya was not normal and told him about the presence of the Obelisk Force . After this , Sora left Crow to deal with Yuya and searched for Moon Shadow and Celina . Sora hid from Obelisk Force and eavesdropped on their intention to signal with flares . When he noticed the flare for Celina , he raced over just in time to rescue Moon Shadow from being sealed into a card . After taking the 2000 LP intrusion penalty , Sora became Moon Shadow ' s tag partner . Moon Shadow assisted Sora with " Barrier Ninjitsu Art of Hazy Transfer " to allow " Frightfur Bear " to use the effect of " Triple Ancient Gear Hunting Hound " against the Obelisk Force , then use the monsters Summoned by " Chimera " to defeat the Obelisk Force in an OTK . The defeated members retreated back to the Fusion Dimension . At this point , Sora chose to defect from Duel Academy , knowing full well that he could not return there at the cost of his life . Sora and Moon Shadow parted as trusted allies , with the latter rushing to the Underground to gather the Lancers for help and the former racing to aid Celina and Riley in the meantime . Sora eventually found Yuya , Riley , and Celina just in time . By using " Frightfur Leo " , " Frightfur Sheep " , and " Frightfur Sabre - Tooth " , he rescued Celina from a batch of Obelisk Force soldiers who were a centimeter away from capturing her , as Riley was too traumatic and tired to start another Duel and block the Obelisk Force ' s way , and Yuya was locked in a tough battle with Barrett . Celina was initially wary of him due to his past with Shay , but in front of Barrett , Yuri , and the Obelisk Force , he pledged his allegiance to Yuya and Celina , much to Yuya ' s joy . However , Yuri arrived and challenged Sora to a Duel as Celina was too weak to Duel . When Yugo appeared , one of the Obelisk Force members had " Ancient Gear Hunting Hound " bite Sora ' s Duel Disk arm , leaving Sora unable to move or start a Duel with the Obelisk Force and helplessly watched as Yuya , Yugo , Yuri , and the Four Dimension Dragons went on a synchronized awakening again . He was horrified when Zuzu appeared and witnessed Yugo and Yuri teleport away as well as Yuya coming back to his senses . He watched helplessly while struggling vainly to free himself as he screamed at Barrett not to take back Celina . 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 Yuri . He was surprised to see Yuya take damage just to free Zuzu . Once Yuya was defeated and Moon Shadow bore grave injuries from unsuccessfully blocking Sergey ' s way , Sora took Zuzu ' 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 . Gong , Sylvio and Chojiro found their group with Riley clinging to Sora in rare trust . Sylvio accused Sora of Yuya and Moon Shadow ' s , but stopped once he saw Riley hanging onto Sora . Sora went to rescue Zuzu from Roget with Moon Shadow , despite Sylvio ' s initial protests and Yuya ' s desire to come with them . Once at Sector Security ' s Main Bureau , they noticed its heavy security and were forced to sneak in another way . Once inside , they were forced to Duel the mind - controlled Stomptroopers . Realizing their mind control , they went to the control room and turned it off , releasing all of Sector Security from Roget ' s control and subsequently freed Zuzu . Before the three of them could escape the building , however , Roget intercepted them and defeated Sora and Moon in a Duel , taking Zuzu from them once more . Despite his serious injuries , Sora used the broadcast system to inform Yuya ( and New Domino City ) that Roget was taking Zuzu back to Duel Academy . The broadcast was cut off abruptly by an explosion . Sora was revealed to have survived the explosion , as he reunited with Yuya , Crow , Jack and the Lancers despite his badly injured state . He apologized for failing to prevent Duel Academy and Roget and to keep Celina and Zuzu safe . Using a hacking app on his Duel Disk , he managed to hack into and successfully force open the door to the room where Zuzu , Roget , and Declan were . Due to his injuries , Sora received a piggyback ride from Gong . Sora and the Lancers happily witnessed Yuya ' s and Zuzu ' s reunion . He heard Roget ' s plans to trap New Domino City in between dimensions and take the Lancers to the Fusion Dimension . The machine activated and Sora witnessed Roget disappearing in the wormhole . Unfortunately he could not prevent Zuzu , Yuya , Shay , Sylvio , and Gong from being swept into a second wormhole moments later . Sora explained what a wormhole was to Crow and Jack and regrouped with the others . They all worriedly looked up toward the sky as currently there was no way to find out about his missing friends ' whereabouts . Heartland City . Sora and Crow joined the Lancers , and they traveled to the Fusion Dimension after being urged to go by Shinji Weber and Chojiro Tokumatsu . They procured a speedboat and they came upon Yuya falling from the mast of Captain Cutter ' s ship ; Crow saved him , but Solo ' s ship fired on them after Solo activated " Battle at Sea " . Sora then joined the Duel , and he told the Captain that it had been awhile and made fun of him for still dressing as a pirate . He was angered when Cutter told him that Celina had returned to him , but told Solo that they were taking Celina back and defeating him . When Sylvio tried to tell Sora about the effect of " Captain Lock " , Sora already knew how to counter it ; he Fusion Summoned " Frightfur Kraken " , which caused the effect of " Lock " to destroy itself . However , Solo brought " Lock " back with its effects negated and strengthened its ATK with " Perished Pirate " . Yuya then assisted Sora with " Performapal Big Support " to win the Duel . When Yuya thought there was a reason why Celina kidnapped Zuzu , Sora told him that the Professor had someone who could control people ' s hearts and minds . Yuya asked him why the Professor wanted Zuzu and her counterparts , and Sora suggested that they might be connected to the Arc Project . Sora learned that Declan went to Duel Academy three years ago and asked Yuya ' s father for help . He also learned that Declan found out about Revival Zero , another part of the Professor ' s plan involving Celina and Yuri , and that it might include Yuya as well . He and other Lancers were told by Declan to believe in their friends strength and fight to the very end . After arriving on the island , Sora told Sylvio that the mountain was closer to the Professor ' s lab and prepared to climb it . After climbing up the mountain , they were surrounded by Duel Academy students before utilizing their plan to split into two groups with Sora , Declan , and Riley continuing to the lab while Yuya ' s group Dueled the students . Along the way they met up with Yusho and Alexis but were confronted by Yuri . When Alexis pushed Yuri to the wall , Sora activated the fence to trap him in . However , after pushing Riley out of the way he got trapped between the fence , which disabled his Duel Disk . He watched Alexis try to seal Yuri attacks but was surprised destroyed his own card . He was mad when Yuri claimed " Ancient Gear Reactor Dragon " , a Tribute Monster , was a trump card of the Honor Student Deck . He got worried when Alexis lost most of her LP in one turn but happy when took control of " Reactor Dragon " . He was surprised when Yuri used " Super Polymerization " and watched him defeat Alexis , sealing her into a card . He then wondered why the fence was deactivating and learned Yuri had control over them as well . He Dueled Yuri and used " Frightfur Fusion " to Fusion Summon " Frightfur Chimera " . He destroyed " Ancient 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 Yuri directly with " Hydra " . He is forced to return " Hydra " when Yuri used " Ancient Gear Inspection " and was defeated by " Ultimate Ancient Gear Golem " . He was about to be sealed into a card until Yugo and Aster arrived . Duel Academy . Sora told Aster that he heard that Yuya got him to join him . He then commented about how there are two other people who look like Yuya . When Yugo and Yuri enter a synchronized awakening again , Sora remembered how it was the same as last time . When the Four Dimension Dragons resonated again , Sora watched " Clear Wing " and " Starving Venom " resonate . When Aster returned , Sora told him to stop the Duel . While watching the Duel , Sora remembered how Aster graduated from Duel Academy and was appointed Commander - in - Chief and that he never liked him . He watched Aster free Yugo from his awakening and tried to join the Duel when Yuri defeated Aster and Kite , but was too hurt . He was surprised when Yuri defeated Yugo and watched Yuri absorb him . He and Aster then went to go find Yuya and the others before they saw the world distorting around them . They arrived at the inner chambers and were caught in the Isolation Dome , separated from the Earth . He ran to check on Yuya and learned that Yuri sealed Yusho into a card . Sora then prepared to Duel Yuri with Declan , Riley , and Aster to protect Yuya , but Yuri knocked them back . He told Yuya he believed him after Declan revived his broken spirit from discarding " Smile World " . He saw Yuto and Yugo supporting Yuya to defeat Yuri and noted that he would win after Yuya used the effect of " Dark Rebellion " . He watched Yuya defeat Yuri and told him that Yuya won ' t absorb him since Yuto and Yugo felt the same way and lent their power to him . However , Sora was shocked when Yuya fell under Zarc ' s will and summoned " Astrograph Sorcerer " to fuse with the Four Dimension Dragons . He then ran outside with Declan , Riley , and Aster to find the world floating in pieces before confronting the Supreme King Z - ARC . When Zarc introduced himself , Sora wondered where he was to summon that huge dragon . After Zarc launched an attack after Sora questioned about the fear of the students of Duel Academy , Sora was shocked that they gave birth to him . He then watched the City being attacked by Zarc and accepted Aster ' s offer of help . After protecting the citizens from Supreme King Z - ARC ' s attack , Sora and Aster challenged him to a Duel , telling him to stop hiding . When Zarc took on his human form , Sora asked Zarc if Yuya was still there . Zarc replied that Yuya no longer existed . He was also surprised when Zarc could Pendulum Summon as well with scales 0 and 13 . He told Aster that Yuya was somewhere inside of him after watching it . He took damage from the effect of " D - Soul Burst " and was surprised at Zarc ' s LP raising to 7000 . He then told Yuya his Dueling would remind him of his and used " Frightfur Sanctuary " to send " Edge Imp Frightfuloid " , " Frightfur Bear " , and " Tiger " to the Graveyard and treat " Edge Imp " as a Frightfur . He then used " Frightfur Fusion " to Fusion Summon " Chimera " and destroyed " Darkwurm " , but Zarc used the Pendulum Effect s of " Supreme King Gate Zero " to reduce the effect damage to zero and " Supreme King Gate Infinity " to increase his LP by the damage would ' ve taken . He then tried to use the effect of " Chimera " to Special Summon " Darkwurm " to his field , but Zarc reminded him Pendulum Monsters return to his Extra Deck . However , Sora revealed he already knew and tried to make Yuya remember his past by showing him his pendant and even called him teacher , but it failed as Zarc simply smirked , causing Sora to shed a tear . When Zarc revived his " Darkvrms " , Aster used " D - Hyper Nova " to destroy all of his monsters while Sora used " Frightfur Mad Parade " to inflict damage for every monster destroyed . However , they were surprised when Zarc brought out " Astrograph Sorcerer " , the monster that brought him back , to revive his monsters . When Zarc used the second effect of " Astrograph Sorcerer " to banish the Four Dimension Dragons and Integration Summon " Supreme King Z - ARC " . After Sora and Aster ran away from the area as it was getting destroyed , they were surprised at Zarc fusing with a Duel Monster and that huge dragon was really him . They were also surprised when Shay and Kite joined the Duel due to " Crossover " activating . But , Sora and Aster were then defeat by the effect of " Zarc " and sent flying . He was checked on by Shay and asked him to save Yuya , giving him Yuya ' s pendant . When Zarc used the effect of " Supreme King Servant Dragon Dark Rebellion " to protect " Zarc " from " Rise Falcon " , Sora noted that " Zarc " can ' t be attacked because its the integration of all Summon ing methods . Gong and Sylvio found Sora and Aster and they told them how Yuya became Supreme King Z - ARC , including how they were trying to regain Yuya ' s heart through Dueling . He was surprised when Zarc defeated Shay and Kite . He was also surprised to learn to Crow sealed into a card , Zarc ' s negative reaction to Dueltaining , and the effect of " Supreme King Servant Dragon Clear Wing " equip ped with " Supreme King Violent Spirit " to destroy all of Gong ' s monsters . When Jack was going up the highway , Sora noted that he had no hesitation . When Jack attacked " Clear Wing " , Sora and Aster 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 . He was also surprised when Crow negated the effect of " Zero " and dealt damage to Zarc . When Zarc forced " Assault Blackwing - Chidori the Rain Sprinkling " to attack " Zarc " , Sora and Aster wondered why . He was also surprised when he thought Sylvio defeated Zarc with " Abyss Script - Abysstainment " and when Zarc used the monsters he destroyed to protect " Zarc " . Sora and Aster were surprised when Leo Akaba joined the Duel and watched Zarc defeat Sylvio and Crow , sending them crashing onto a building ' s roof . He and Aster were happy when Declan ] ] managed to dealt damage to Zarc . Sora was surprised when he thought " Zarc " killed Declan . He and Aster were happy when Ray turned all of Zarc ' s Fusion Monsters into Normal Monster s with their effects negated . Following the battle against Zarc , Sora met with Yuya , who just arrived in the Fusion Dimension , and ran to take him to Shay , who was attempting to enter Leo ' s chambers as Alexis tried to stop him . Yuya challenged Shay to a Duel , but Shay denied his challenge . Sora realized that Shay wouldn ' t listen to them about Ray , and he asked Alexis to let Shay in . Sora watched as Leo observed the floating specter of what he predicted would become Zuzu , and as Leo admitted his fault in destroying the lives of Ray ' s fragments . Sora and Alexis watched Yuya and Shay ' s Duel , and Sora noted that Shay and Yuya were going all - out from the start as they countered one another with Action Card s . He was shocked to see that Shay had continued to evolve when he Ranked - Up " Revolution Falcon " into the Rank 12 " Raidraptor - Final Fortress Falcon " . Yuya eventually won the Duel , but as Yuya and Shay declared that there was hope for Zuzu , Yuto and Lulu , Jack then declared that Yuya couldn ' t save them in his current state . As Sora watch Yuya hesitating during his Duel with Shay , he asked if Yuya was afraid and wondered why . Jack clarified that Yuya was afraid of using the Four Dimension Dragons for fear of integrating with them again . Sora learned that Shay and Dennis ' Duels with Yuya didn ' t make Riley smile as they had been intended to do , and he was surprised when the Dimension Highway activated throughout the Four Dimensions . Crow brought Yuya his Duel Runner and Turbo suit , and Sora watched the Turbo Duel with Crow , Shay , and Alexis . He was worried when Yuya was pushed into a corner . When Crow was surprised at " Starving Venom ' s " effect to negate and steal monster effects , Sora told him that was only half of it . When " Starving Venom " gained " Scarlight Red Dragon Archfiend " and " Tyrant Red Dragon Archfiend ' s " ATK , Sora told Crow this was Yuri ' s dragon ' s power . When Crow knew Jack was anticipating Yuya ' s next move , Sora told him he called it . He bump fists with Alexis when Yuya won and watched his Duel with Declan . Sora was surprised when Yuya Fusion Summoned " Odd - Eyes Venom Dragon " and purified " Starving Venom " . He was also surprised when Yuya destroyed " Odd - Eyes Wing Dragon " on purpose to Xyz Summon " Odd - Eyes Rebellion Dragon " and when Declan survived Yuya ' s attack . He watched Yuya and Declan gather action cards to in order for one of them to win the Duel first due to the effect of " Performapal Five - Rainbow Magician " . Sora was happy when Yuya won and was sent to the Pendulum Dimension by Ray to witness her revival as Zuzu and was surprised to see Celina ' s spirit revived as well . Relationships . Yuya Sakaki . Sora considers Yuya to be one of his first friends , as there was no time for such things while training at Duel Academy , as everyone was too focused on becoming soldiers . Yuya found him annoying at first , but this quickly changed . Sora still considered Yuya his friend even though Yuya opposes Duel Academy . With encouragement from Yuya and Zuzu , Sora realized he was hurting people and reluctantly abandoned his old ways . It is , in the end , Yuya ' s words and the fact that Zuzu was in danger from Duel Academy , is what convinces Sora to betray Duel Academy and become Yuya and Zuzu ' s ally , defeating the Obelisk Force and rescuing Moon Shadow to prove his sincerity . Following Zarc ' s revival after Yuya ' s victory over Yuri , he dueled alongside Aster in attempt to get through to Yuya , but when Zarc did not react to any of Sora ' s moves ( moves that he used against Yuya ) , Sora began crying , believing his first friend to be dead , showing that he truly cared for his friend . Initially , during his first Duel with Shay , Sora attempted to act like Yuya and be a Dueltainer , even calling for a spotlight on numerous occasions to highlight his best moves . Zuzu Boyle . Sora considers Zuzu one of his friends , for the same reasons as Yuya . Sora taught Zuzu to Fusion Summon , but initially claimed it wasn ' t due to friendship , though he would later admit that it was . Though still devoted to Duel Academy , Sora was willing to interfere with Leo Akaba ' s plans in order to protect Zuzu , willing to allow Zuzu to return to Standard with Yuya if Yuya would agree to trade him Celina . With encouragement from Yuya and Zuzu , Sora realized he was hurting people and reluctantly abandoned his old ways . It is , in the end , Yuya ' s words and the fact that Zuzu is in danger from Duel Academy , that convinces Sora to do the ultimate act of betrayal and become Yuya and Zuzu ' s ally : defeating the Obelisk Force and rescuing Moon Shadow . Leo Akaba . Sora used to be quite faithful to Leo , but there were cases where Sora wasn ' t . For example , Sora was commanded by Leo to capture Celina , but Sora decided to hunt down Shay instead . His loyalty to Leo dropped completely after reluctantly turning against Duel Academy to help Yuya and Zuzu . Shay Obsidian . Before abandoning Duel Academy , Sora hated Shay because of his Xyz background . He enjoyed Dueling Shay , declaring that the Duels were " hunting games " . Sora was angry that he lost to Shay on their first Duel , but became much more satisfied when Shay lost . Sora told that he was from Duel Academy to Shay before anyone else , who also knew of its existence . Shay was Sora ' s target when Leo commanded Sora to go after Celina . While the two didn ' t interact at all in the Synchro Dimension , Shay somehow knew about Sora becoming a traitor to Duel Academy , as he showed sense and rationality whenever Sora was mentioned and did not treat him with hostility when they finally met . It was shown after Sora ' s defeat at the hands of Zarc that the two no longer hold any resentment toward one another and treat each other as allies , with Sora pleading to Shay to rescue Yuya from the darkness . Deck . Sora uses a " Fluffal " / " Edge Imp " Deck focused on Fusion Summon tactics , with " Toy Vendor " assisting in swarm ing . As Fusion Summoning requires a large number of specific cards , Sora uses cards such as " Edge Imp Saw " and " Fusion Conscription " to acquire them easier . He also uses cards such as " Frightfur Factory " and " Frightfur Fusion " which give him easier access to his " Frightfur " monsters . He also uses effects to treat his monsters as " Frightfur " monsters , in order to use his " Frightfur Chimera " easier . Although Sora prefers to Fusion Summon " Frightfur Bear " to easily acquire ATK power , he is also flexible and can Fusion Summon different monsters should the need arise , such as " Frightfur Leo " to destroy difficult monsters , " Frightfur Sheep " to disable the opponent from activating cards , and " Frightfur 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 .
