'''Shay Obsidian''', known as '''Syun Kurosaki'''<ref name="TVTokyo">{{citeweb|url=http://www.tv-tokyo.co.jp/anime/yugioh-arcv/chara/index_2.html|title=TV Tokyo Yu-Gi-Oh! ARC-V Characters|date=April 5, 2015}}</ref><ref name="ep59">{{episode|Yu-Gi-Oh! ARC-V|59|ref}}</ref><ref name="ep70">{{episode|Yu-Gi-Oh!

He is a Duelist from the [[Xyz Dimension]] who is one of [[Yuto]]'s comrades and serially attacked the [[Leo Institute of Dueling]] with the intention of rescuing his younger sister [[Lulu Obsidian]]. After realizing he had similar goals to [[Declan Akaba|Declan]] and learning his true target, the two agreed to cooperate, and he subsequently became one of the first [[Lancers]].

}}
Shay is a young man with straight blueish-black hair that falls to his chin, and light green bangs in the shape of a wing partially tucked under some strands on the left. He has yellow-green eyes, and similar to [[Yuto]], used to keep his face concealed behind dark glasses and a red scarf signifying his allegiance to the Resistance. He wears a blue trenchcoat that is tattered at the ends; the coat is belted shut, and is adorned with belted cuffs. He also sports grey pants and brown shoes.

[[File:Shay in a Turbo Duelist Outfit.png|thumb|right|150px|Shay as a [[Turbo Duel]]ist]]
Shay wears a [[Turbo Duel]]ing suit in the [[Underground Dueling Arena]] and during the [[Friendship Cup]]. It has a dark blue and green color scheme and he wears his Resistance scarf with it. In the past during his time at the [[Spade Branch]] of [[Heartland Duel School]] he wore more casual clothes; a dark grey shirt under a lighter one, dark jeans, and casual sneakers.

===Personality===
Deep inside his heart, Shay is a kind person with good intentions, but the horrors he has suffered due to Duel Academy have scarred and hardened his views deeply. Though he Dueled for fun before in a pro Duelist training school, in the present, Shay is a battle-hardened [[Duelist]] who shows nothing but fierce determination and serious perseverance in his Duels. In the dub, he tends to be more sarcastic. In a similar manner to [[Seto Kaiba]], [[Reginald Kastle]], [[Kite Tenjo]], and [[Declan Akaba]], he also carries an affection for his younger sister [[Lulu Obsidian]] whom he vows to rescue, and also highly regards his comrades. Unlike [[Yuto]], Shay acts out more recklessly and impatient and is willing to crush anyone who he deems as his enemies, even warning Yuto not to stand in his way when focused on his goal. He demonstrates a powerful hatred of [[Fusion Summon]]ing, and previously of [[Leo Institute of Dueling|LID]], as Fusion Summoning has been used by his enemies and he believed LID to be associated with them. Despite his callous disposition, he can be pragmatic, agreeing to cooperate with Declan in furthering his machinations in exchange for information. Shay's time at the pro Duelist school educated him with an "iron will and steeled strength", concepts that he evaluates other Duelists on, and he also developed a serious outlook between Duelists exchanging their cards.<ref name="ep119">{{episode|Yu-Gi-Oh! ARC-V|119|ref}}</ref>

Shay tends to converse about his experiences when the comments of other people allude to them (whether such allusions are intentional or not). While Dueling, he demonstrates a more violent side when he uses "[[Raidraptor - Rise Falcon (anime)|Raidraptor - Rise Falcon]]". Aside from these moments, he says little when he doesn't have to talk, not even bothering to learn the names of many of his opponents; he simply chAlanges them to a Duel. However, he often employs the word "revolution" and similar terms, reinforcing his strong belief of Dueling solely to defeat his enemies and protect his comrades. Despite his determination to protect his comrades, he initially prefers acting alone and dislikes it when others try to protect him by risking themselves but he drops this attitude after his duel against Crow where he is completely fine in helping his new comrades and often comes to aid the [[Lancers]]. However, the memories of the attack on his homeland have clearly scarred him, and when he was in the "[[Neo Heartland City]]" Action Field for a second time, he was initially unwilling to discuss the events, but on later prompting by [[Celina]], he admitted that the faces and laughter of [[Duel Academy (ARC-V)|Duel Academy]] students that had attacked [[Heartland City (ARC-V)|Heartland]] would always remain in his mind. Shay has confirmed that he sees life as a battlefield and everyone else an enemy due to the loss of everything as a result of the attack on Heartland. This is especially shown during and after [[Yu-Gi-Oh! ARC-V - Episode 074|his Duel with Dennis]] during the Friendship Cup, where he pushed his opponent to reveal his true nature. In the dub, Shay even claims to Celina that it hurts to look at her due to her resemblance to Lulu.

Despite his hot-headed nature he is shown to care deeply for his comrades including Yuto and Lulu. This was seen many times during his Duels against [[Sora Perse|Sora]] and [[Dennis McField|Dennis]]. He is shown to be arrogant and to have great pride in his skills. Shay initially didn't see any of the Lancers as his comrades but this changes during his duel against Crow which reminded him of something important to him, and he began to trust the Lancers and consider them as his comrades. This was seen when he approached Kite and defended the Lancers, also stating that he believed in Yuya as well. He later came to accept [[Crow Hogan (ARC-V)|Crow Hogan]] as a comrade after their Duel, discovering that they had a lot in common.

Shay is shown to be very protective of and has a soft spot for children. This was seen during his Duel against Crow when he saw [[Tarren]] clinging to the back of "[[Assault Blackwing - Raikiri the Rain Shower (anime)|Assault Blackwing - Raikiri the Rain Shower]]" and showed genuine concern for him. He also expressed this towards [[Riley Akaba|Riley]] when the Lancers were about to depart for the [[Synchro Dimension]] and when he found out that Riley was protecting Celina all on his own from the Obelisk Force. He stated that the reason he started fighting was to protect children.

Shay has a habit of saying "[[field]]" in kanji (「{{Ruby|場|ば}}」, ''Ba'') instead of in katakana (「フィールド」, ''Fīrudo''). In the dub, he makes a small number of bird and flight puns regarding his "[[Raidraptor]]s".

===Abilities===
Like [[Yuto]], Shay's [[Duel Disk]] possesses the ability to materialize the [[card effect|effects]] of ''[[Duel Monsters]]'' cards. The Disk also has the power to seal a person inside a card, though unlike previous uses of this power in the franchise, the entire person, and not just their soul. His Duel Disk is later upgraded with the function to produce an Action Field, and also appears to have dimensional travel technology incorporated into it. However, [[Declan Akaba|Declan]] modified it so that he could not seal a person anymore, and also seemed to have reduced its ability to materialize the effects of a Duel.<ref name="ep75">{{episode|Yu-Gi-Oh! ARC-V|75|ref}}</ref> Shay is highly acrobatic and athletic, as seen when he jumped off of the sides of several buildings and rolled along the ground to break his fall during his first Duel with [[Sora Perse]]. He is also a highly skilled fighter, strong enough to defeat several guards each with a single blow while escaping from the [[Facility (ARC-V)|Facility]] in the [[Synchro Dimension]].

===Etymology===
His name in the dub, "Shay", is Gaelic for "hawk". His name could also refer to [[wikipedia:Shays' Rebellion|Shays' Rebellion]], a famous historical uprising, given the fact that rebellion is a key aspect of his character. His dub surname, "Obsidian", is a glassy black volcanic material; an appropriate name for one having gone through the stress that Shay has. His Japanese name, Syun「{{Ruby|隼|しゅん}}」, means "falcon", alluding to his [[Xyz Monster]]s, while his last name can translate to "black blossom". Both of his last names are likely a reference to the black borders of Xyz Monsters.

==Biography==
===History===
[[File:Lulu, Yuto, and Shay in the past..png|thumb|Shay with [[Lulu Obsidian|Lulu]] and [[Yuto]] watching [[Kite Tenjo (ARC-V)|Kite]]'s Duel.]]
Shay's homeland, [[Heartland City (ARC-V)|Heartland City]] in the [[Xyz Dimension]], was once a place where [[Duelist]]s were loved and everyone enjoyed Dueling. Shay attended the [[Spade Branch]] of [[Heartland Duel School]]<ref name="ep101" /> known for training professional Duelists.<ref name="ep75"/> Shay was a rival to [[Kite Tenjo (ARC-V)|Kite Tenjo]], the ace of the [[Clover Branch]].<ref name="ep101" /><ref name="kitetvtokyoprofile">{{citeweb|url=http://www.tv-tokyo.co.jp/anime/yugioh-arcv/chara/index_2.html|title=Yu-Gi-Oh! ARC-V characters|publisher=TVTokyo.com}}</ref> Whenever the two Dueled, they drew large crowds of children who looked up to them.<ref name="ep105">{{episode|Yu-Gi-Oh! ARC-V|105|ref}}</ref> Shay and Yuto watched Lulu's Duel as the latter commented on her great Dueling skills. Shay told Yuto that she was his sister and after her Duel, he introduced them both to each other.<ref name="ep124">{{episode|Yu-Gi-Oh! ARC-V|124|ref}}</ref> At one point Shay, [[Yuto]], and [[Lulu Obsidian|Lulu]] watched a Duel of Kite's from the audience at an arena.<ref name="ep101" /> Shay witnessed Lulu lose to [[Saya Sasayama]], and was furious both that she lost and that she accepted a card from Saya due to his opinion on such matters and he slapped the card from her hands.<ref name="ep119" />

[[File:Shay Flashback Invasion.png|thumb|left|Shay during [[Invasion of Xyz Dimension|the invasion]].]]
Heartland was [[Invasion of Xyz Dimension|attacked without warning]] one day by [[Duel Academy (ARC-V)|Duel Academy]] from the [[Fusion Dimension]], and without an organized defense, lost comrade after comrade to their foes until they learned to fight back.<ref name="ep33">{{episode|Yu-Gi-Oh! ARC-V|33|ref}}</ref> On one occasion, Shay fled from several materialized "[[Chaos Ancient Gear Giant (anime)|Chaos Ancient Gear Giant]]s" during the early days of the attacks on Heartland.<ref name="ep74">{{episode|Yu-Gi-Oh! ARC-V|74|ref}}</ref> He, Yuto and three other Duelists attempted to fight off the "Chaos Giants", but the other Duelists eventually lost and were sealed into cards, forcing Shay and Yuto to retreat.<ref name="ep75" />

After capturing a Duel Academy Duelist, Shay and Yuto questioned him about the reason behind the assault. After the interrogation, Shay tried to seal the Duelist into a card, but Yuto prevented him from doing so.<ref name="ep100">{{episode|Yu-Gi-Oh! ARC-V|100|ref}}</ref>

Shay and four [[The Resistance|other Duelists]] arrived to witness Yuto Dueling [[Yugo]]. Upon arriving, Yugo fled on his [[Duel Runner]] and Shay asked Yuto where Lulu was. Yuto shook his head in response, prompting him to curse.<ref name="ep18">{{episode|Yu-Gi-Oh! ARC-V|18|ref}}</ref>

At some point after that, Shay cornered another Duel Academy Duelist, who informed him that [[Declan Akaba|Declan]] was the Professor's son. Shay theorized that taking Declan hostage would force the Professor, [[Leo Akaba]], to return Lulu and then proceeded to seal the Duelist into a card, despite the Duelist begging for mercy.<ref name="ep100" /> He traveled to the [[Standard Dimension]] to oppose the Fusion Dimension, and Yuto soon pursued him.<ref name="ep36">{{episode|Yu-Gi-Oh! ARC-V|36|ref}}</ref><ref name="ep103">{{episode|Yu-Gi-Oh! ARC-V|103|ref}}</ref>

===Pre-Arc League Championship===
[[File:ShayDuelDiskScan.png|right|thumb|Shay scanning [[Leo Institute of Dueling]] with his [[Duel Disk]].]]
Having found out that [[Leo Institute of Dueling]] was run by [[Declan Akaba]], and knowing that [[Duel Academy (ARC-V)|Duel Academy]] was run by [[Leo Akaba]], Shay determined them to be allied with one another. He conspired to draw out Declan in order to defeat and capture him, hoping to use him in a prisoner exchange with Leo to get [[Lulu Obsidian|Lulu]] back.<ref name="ep25" /> To this end, he assaulted [[Marco (ARC-V)|Professor Marco]], the teacher of LID's [[Fusion Summon]] course. He defeated Marco in a Duel and sealed him in [[Marco (card)|a card]].<ref name="ep18" /> Sometime later, he surveyed LID from a nearby rooftop. His face concealed, he seemed to be analyzing or searching for something in LID with his [[Duel Disk]]'s radar.<ref name="ep15">{{episode|Yu-Gi-Oh! ARC-V|15|ref}}</ref>

[[File:ArcV 018.png|thumb|left|Shay Dueling [[Herc]].]]
He later Dueled [[Herc]], another LID employee, and was witnessed by [[Yuto]] after the latter was warped there by [[Zuzu's bracelet]]. Shay defeated Herc with his [[Raidraptor - Rise Falcon (anime)|ace monster]] and sealed him inside [[Herc (card)|a card]] as he had with Marco and sent both cards to LID. He later unwittingly saved [[Yuya Sakaki]] from three LID elites and [[Curio Sawatari]], who were pursuing Yuya under the latter's orders. Yuya asked Shay on what was going on, but he gave no response. Shay [[Xyz Summon]]ed again and defeated the three elites with his ace monster, sealing them in cards and damaging the nearby overpass. Yuya was knocked out in the process, while Curio was scared off.<ref name="ep18" />

[[File:Shay gets punched.png|thumb|right|Yuto restrains Shay by punching him in the gut.]]
When [[Julia Krystal|Julia]] confronted [[Zuzu Boyle|Zuzu]] and [[Sora Perse|Sora]] and mentioned she was from LID, Shay appeared before her and knocked Zuzu aside, insisting that he would be Julia's opponent. Yuto arrived and attempted to hold Shay back, only for Shay to protest. When Shay noticed Zuzu, he mistook her for Lulu and asked if she had managed to escape with her own strength. Yuto knocked Shay unconscious with a punch to the gut, insisting that she wasn't Lulu, then carried him bodily over the shoulder. Yuya was en route at the time and as he approached, Zuzu's bracelet teleported Yuto and Shay away.<ref name="ep21">{{episode|Yu-Gi-Oh! ARC-V|21|ref}}</ref> Yuto later reiterated to Shay that Zuzu was not Lulu, as he'd seen her learning Fusion Summoning with a smile on her face, something that Lulu would never have done.<ref name="ep25">{{episode|Yu-Gi-Oh! ARC-V|25|ref}}</ref>

Shay moved to ambush Julia later, coming across her in an abandoned street and asking if she was alone and inquiring about Sora and Zuzu's whereabouts. Julia replied that she didn't know and planned to avenge Professor Marco. Shay insulted Marco for his lack of strength and determination. He admitted to her that he had indeed been the attacker of all the LID students, and urged her to sate her rage by defeating him in a Duel. Noting that she'd called in her friends, he claimed that she was underestimating him if she thought that two more would be sufficient to defeat him. Julia revealed that she'd been using herself as bait, sure that Shay would come after her. Her friends, [[Dipper O'rion|Dipper]] and [[Kit Blade|Kit]] arrived, while LID monitored the proceedings. Claiming it made no difference, Shay chAlanged all three of them to a [[Battle Royal]].<ref name="ep24" />

[[File:ArcV 024.png|thumb|left|Shay defeats [[Kit Blade|Kit]], [[Julia Krystal|Julia]] and [[Dipper O'rion|Dipper]].]]
Julia took the first [[turn]], and Shay took the second, emptying his [[hand]] to call out his three "[[Raidraptor - Vanishing Lanius (anime)|Raidraptor - Vanishing Lanius]]", [[Set]]ting two cards before ending his turn. Dipper and Kit made use of their powerful "[[Constellar]]" [[Xyz Monster|Xyz]] and "[[X-Saber]]" [[Synchro Monster|Synchro]] [[Monster Card|monsters]] respectively to [[destroy]] Shay's Set cards, return all of his monsters to his hand, and then [[discard]]ing them. When Julia brought out [[Fusion Monster]]s, Shay looked angry at seeing the monsters of his enemy. Julia then inflicted [[effect damage]] twice, but before the second instance could defeat Shay, he used his "[[Raidraptor - Readiness (anime)|Raidraptor - Readiness]]" [[Trap Card|Trap]] from his [[Graveyard]] to reduce his [[Life Points]] to 10 and survive the turn. He expressed that he couldn't feel a steeled strength or an iron determination from their Dueling, while saying that in fighting his enemies, he learned to stand up from defeat to strike back at them until the day they're finally eradicated. He drew "[[Dimension Xyz]]" and used it to [[Xyz Material|overlay]] the monsters in his Graveyard to call out "[[Raidraptor - Rise Falcon (anime)|Raidraptor - Rise Falcon]]". Using its effect, it gained [[ATK]] equal to the ATK of all [[Special Summon]]ed monsters his opponents controlled, raising its ATK to 16400 and allowing it to attack all their monsters, defeating all three of them. Before he could seal them in cards, more LID staff arrived, including [[Claude]]. Shay mocked them, having expected them to show up, and asked them to send out their boss. Their boss in question, [[Declan Akaba|Declan]], revealed himself instantly, walking towards Shay grimly, commenting that if he wanted him, he had him.<ref name="ep24" />

Declan introduced himself as [[Leo Corporation]]'s current President. Shay immediately chAlanged him to a Duel, but Declan wanted to know why Shay had been attacking LID students. Shay refused to tell him, but Declan deduced that Shay was fighting to rescue his comrades, and thus attacked LID members in order to draw Declan out, hoping to use him as a hostage against Declan's father, [[Leo Akaba]]. Shay confirmed that, but was surprised when Declan claimed that he didn't mean that much to his father. Declan agreed to Duel Shay as long as Shay met his conditions — entering the [[Junior Arc League Championship]]. He informed Shay of a [[Sora Perse|powerful Fusion user]] and [[Yuya Sakaki|a Duelist]] who used a [[Pendulum Summon|Summoning method]] unknown to Shay, explaining that he wanted Shay to aid him in his fight ''against'' Leo.<ref name="ep27" />

===Arc League Championship===
[[File:Declan watching Shay.png|thumb|right|Shay enters the [[Arc League Championship]] under [[Declan Akaba|Declan]]'s watch.]]
Shay kept to his end of the bargain, entering the Junior Arc League Championship under the banner of [[Leo Institute of Dueling|LID]], alongside the students he had not long ago defeated. They had been mind-wiped into believing that he had always been a part of LID. He kept to himself, standing apart from the group, and soon found he was scheduled to Duel the [[Fusion Monster|Fusion]] user that Declan had spoken of, Sora Perse.<ref name="ep27" /> He happened to cross paths with Sora later that day, sparing him a glance.<ref name="ep28">{{episode|Yu-Gi-Oh! ARC-V|28|ref}}</ref> Later, he watched the Duel between [[Julia Krystal|Julia]] and [[Zuzu Boyle|Zuzu]] and reacted significantly to the latter's Fusion Summon, but left before the Duel ended.<ref name="ep29">{{episode|Yu-Gi-Oh! ARC-V|29|ref}}</ref> He also calmly observed the new Summoning method that Declan had informed him about, the [[Pendulum Summon]] when it was used by [[Yuya Sakaki]] and [[Sylvio Sawatari]].<ref name="ep31">{{episode|Yu-Gi-Oh! ARC-V|31|ref}}</ref><ref name="ep32">{{episode|Yu-Gi-Oh! ARC-V|32|ref}}</ref> Before his match with Sora, [[Claude]] tried to give Shay a [[Pendulum Monster|Pendulum Card]] that had been made for him, but Shay refused it and walked away.<ref name="ep33" />

[[File:I Hate This Place.png|thumb|left|"[[Neo Heartland City]]" brings back painful memories.]]
Shay and Sora Dueled in the third match of the second day. Shay was shocked when the Action Field that was chosen for him to Duel on was "[[Neo Heartland City]]" and he didn't participate in the traditional Action Duel opening, simply talking about the attack on his homeland, [[Heartland City (ARC-V)|Heartland City]]. Vowing to show no mercy to the Fusion user, he traded blows evenly with Sora using two "[[Raidraptor - Vanishing Lanius (anime)|Vanishing Lanius]]", even countering the powerful effect of Sora's [[Fusion Monster]] "[[Frightfur Bear (anime)|Frightfur Bear]]". After being accused of only defending, Shay remarked on how they'd had no organized defense in his homeland, and that eventually, they had to learn to win to succeed. He brought out "[[Raidraptor - Rise Falcon (anime)|Rise Falcon]]" and used it to destroy "Frightfur Bear", once again creating a real shockwave. This prompted Sora to start getting serious.<ref name="ep33" /> To this end, Sora Summoned "[[Frightfur Leo (anime)|Frightfur Leo]]", but Shay evaded its effect with [[Action Card]]s and his own Traps. Shay then played "[[Rank-Up-Magic Raptor's Force (anime)|Rank-Up-Magic Raptor's Force]]", [[Rank-Up|Ranking]]-Up his "Rise Falcon" into "[[Raidraptor - Blaze Falcon (anime)|Raidraptor - Blaze Falcon]]", and prompted much surprise on the part of many watching the Duel, including Sora. Sora survived the attack of "Blaze Falcon" and proceeded to Summon it to his [[field]] via the effect of "[[Frightfur Chimera (anime)|Frightfur Chimera]]". He taunted Shay, asking how it felt to be facing defeat at the hands of his own ace monster. Shay responded by explaining that in [[the Resistance]] they'd learned to prepare for the worst, playing "[[Rank-Up-Magic Revolution Force (anime)|Rank-Up-Magic Revolution Force]]", taking back "Blaze Falcon" and defeating Sora with "[[Raidraptor - Revolution Falcon (anime)|Raidraptor - Revolution Falcon]]". After Sora's defeat, he approached him, but Declan warned him not to call any more attention to himself in the eyes of the public. Shay turned and left, ignoring the injured Sora's pleas to Duel him again.<ref name="ep34">{{episode|Yu-Gi-Oh! ARC-V|34|ref}}</ref>

Shay was in LID's monitoring room when Sora escaped from the hospital, and identified [[Yuto]] when Sora encountered him, explaining to Declan who he was. He demanded to be allowed to go and help Yuto several times, but Declan refused to let him.<ref name="ep35">{{episode|Yu-Gi-Oh! ARC-V|35|ref}}</ref> When the images of the area were lost due to [[Yugo]]'s arrival, followed by the detection of a [[Synchro Summon]], Shay realized that Yuto was Dueling the so-called Pawn of Fusion.<ref name="ep37">{{episode|Yu-Gi-Oh! ARC-V|37|ref}}</ref> Two days after [[Claude]] retrieved Yuto's Duel Disk, Shay wanted to talk to Declan, saying that he hadn't been able to contact Yuto since his disappearance, but Claude refused to let him disturb Declan, and kept Shay in the dark about Yuto's Duel Disk.<ref name="ep38">{{episode|Yu-Gi-Oh! ARC-V|38|ref}}</ref> Later, while watching Yuya's Duel with [[Iggy Arlo]], Shay expressed shock when the former Xyz Summoned "[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion Xyz Dragon]]", questioning why Yuto's card was in Yuya's possession.<ref name="ep39">{{episode|Yu-Gi-Oh! ARC-V|39|ref}}</ref> Convinced that Yuya knew what happened to Yuto, Shay decided to confront Yuya directly, but Declan stopped him by reminding him of their plan to use the tournament as a way to reach Leo. Shay sighed and left, with Claude promising to Declan that he would keep Shay under surveillance.<ref name="ep40">{{episode|Yu-Gi-Oh! ARC-V|40|ref}}</ref>

Shay defeated his next Championship opponent, [[Chalac]] from the [[Knights of the Duel Disks]], in a one-sided match. Shay was later present in Declan's office, instead of in the stadium with the other Junior Youth competitors, when Declan rounded up the Top 8 Duelists from the Senior division. After Declan briefed them about the upcoming [[Battle Royal]], he turned to Shay and reminded him that his duty was to observe the Junior Youth Duelists and find the ones with enough potential to join the Lancers. Shay complained that that would mean he couldn't Duel in the next round, stating that he would have no choice but to participate if the Youth Duelists lost, prompting a spiteful response from [[Kev Ravenwood]]. In response, he contemptuously told the Senior Duelists to do their best to stay alive and then left for the stadium, which he entered just as the Battle Royal was about to begin.<ref name="ep41">{{episode|Yu-Gi-Oh! ARC-V|41|ref}}</ref>

Although he was not seen in the opening ceremony, Shay participated in the Battle Royal to determinate potential Lancers candidates.<ref name="ep41" /> His first encounter was in the Ruins Area of "[[Quartet of Quandry]]", where he encountered [[Ashley]], [[Bram]] and [[Carl]], students of the Knights of the Duel Disks who wanted to avenge their companion Chalac.<ref name="ep42">{{episode|Yu-Gi-Oh! ARC-V|42|ref}}</ref> He accepted their chAlange and Dueled the three at the same time, easily defeating them with "Rise Falcon" in a single attack. Shay walked away, thinking they were unfit for the Lancers.<ref name="ep43">{{episode|Yu-Gi-Oh! ARC-V|43|ref}}</ref> He waited in the Ruins Area, where he encountered Yuya. They exchanged questions about each other, but Shay was angry that Yuya had Yuto's "Dark Rebellion Xyz Dragon", and accused him of harming Yuto. Yuya denied this claiming that he did not know what happened, but Yuto entrusted the card to him to make people smile with his Duels.<ref name="ep44">{{episode|Yu-Gi-Oh! ARC-V|44|ref}}</ref>

Before the two could continue their conversation, the previously defeated Knights of the Duel Disks students performed a Battle Royal between themselves with Yuya and Shay at the center launching attacks with their three "[[Assault Knight Slash]]" in order to physically harm the duo while keeping themselves alive through its effect. They further provoked them that they were "Dueling" and if they were displeased, they could join their Duel and pay the 2000 [[LP]] penalty for intrusion. The attack blew away both Shay and Yuya from one another. They caught a glimpse of Sora and members of the [[Obelisk Force]]. Sora declared his intentions of getting revenge on Shay and chAlanged him to a Duel. Ignoring Yuya's pleas, Sora instructed the Obelisk Force to deal with any interference, as the two left to have their Duel.<ref name="ep44" /> Shay started strongly, bringing out three "[[Raidraptor - Force Strix (anime)|Raidraptor - Force Strix]]" on his first turn and maximizing their ATK, before launching his attack. When questioned if he wasn't fighting seriously by Sora, Shay replied that he was always serious when he Dueled, even if he was facing a worthless opponent.<ref name="ep45">{{episode|Yu-Gi-Oh! ARC-V|45|ref}}</ref>

[[File:Shay Loses to Sora.png|thumb|right|Shay loses to [[Sora Perse|Sora]].]]
After a protracted Duel, Sora eventually Fusion Summoned "[[Frightfur Tiger (anime)|Frightfur Tiger]]" and used it to destroy all of Shay's monsters, defeating him and knocking him out of the temple door, past [[Celina]], and down the steps.<ref name="ep47">{{episode|Yu-Gi-Oh! ARC-V|47|ref}}</ref> Badly injured, Shay was rescued by Celina, and further saved when Sora caught up to them by [[Sun Shadow]], who stayed behind to Duel Sora, and [[Moon Shadow]], who accompanied Celina and Shay. Three Obelisk Force members approached Celina, requesting that she come with them, but Celina refused, and Shay stepped protectively in front of her. They began a Duel, and Shay tried to take the first turn, but Moon Shadow initiated instead and protected them with his "[[Ninjitsu Art]]" cards, reassuring Shay when he asked that this was nothing compared to Shay's injuries. Shay tried to take his turn again after the Obelisk Force had all done so, but was this time upstaged by Celina, who he was shocked to see Fusion Summon. Shay witnessed [[Reed Pepper|Reed]] and [[Trout]]'s entrance into the Duel and their subsequent defeat and sealing, as well as the arrival of [[Sylvio Sawatari]], who saved Moon Shadow from the same fate.<ref name="ep48">{{episode|Yu-Gi-Oh! ARC-V|48|ref}}</ref>

[[File:Shay Pendulum Summon with Sawatari cards.png|thumb|left|Accepting assistance, Shay performs a [[Pendulum Summon]].]]
However, even with Sylvio's help, the Obelisk Force still got the upper hand by Summoning "[[Ultimate Ancient Gear Hunting Hound]]". Shay told Sylvio and the others to back down, but before he could start, [[Gong Strong|Gong]] interfered and gave Shay two of Sylvio's Pendulum Monsters, "[[Abyss Actor - Evil Heel (anime)|Abyss Actor - Evil Heel]]" and "[[Abyss Actor - Funky Comedian (anime)|Abyss Actor - Funky Comedian]]" by using the effects of "[[Superheavy Samurai Transporter (anime)|Superheavy Samurai Transporter]]" and two copies of "[[Superheavy Samurai Thief (anime)|Superheavy Samurai Thief]]". Shay asked why he gave him Pendulum cards, which Gong answered that the rest was up to him to decide. Shay thought about the people who had helped him and were sealed into cards, and though he still decried their help as ridiculous, he finally decided to Pendulum Summon. He Pendulum Summoned three copies of "[[Raidraptor - Wild Vulture (anime)|Raidraptor - Wild Vulture]]" and then used them to Xyz Summon "Revolution Falcon". Shay attacked all three of the Obelisk Force's monsters with it, winning the Duel for him and his allies. Afterwards, Shay witnessed the Duel between Sora and Yuya which ended without a result since the Battle Royal timer had ran out. Sora escaped back to the Fusion Dimension, but Declan arrived and with Sylvio, explained that they had passed the test to become Lancers.<ref name="ep49">{{episode|Yu-Gi-Oh! ARC-V|49|ref}}</ref>

===Friendship Cup===
Shay learned that Celina had switched clothes with Zuzu to come and ask him about what had happened in the [[Xyz Dimension]]. When [[Yuya Sakaki|Yuya]] chAlanged Declan to a Duel, Declan used "[[Neo Heartland City]]" again for the Action Field, much to Shay's fury. He refused to talk about his traumatic past to the new Lancers, so Declan explained the basics of what had happened. Celina revealed to Shay that she had originally come to the [[Standard Dimension]] to fight him. When he questioned Celina about what Zuzu had asked her, Shay confirmed what Zuzu had said; that Duel Academy students had hunted innocent people as if it were a game and that their faces and laughter would be forever in his memory. He then asked Celina why she resembled Lulu (in the dub, he says it hurts to look at her because she looks exactly like Lulu).<ref name="ep50">{{episode|Yu-Gi-Oh! ARC-V|50|ref}}</ref> He was surprised when he realized that Yuya's Pendulum-Xyz Summoning had likely been born out of Yuya's promise to [[Yuto]] and shocked to see the Summoning of "[[Odd-Eyes Rebellion Dragon (anime)|Odd-Eyes Rebellion Dragon]]".<ref name="ep51">{{episode|Yu-Gi-Oh! ARC-V|51|ref}}</ref>

The following day, Declan gathered the Lancers, including his little brother [[Riley Akaba|Riley]]. Shay was dismissive of the boy, believing that he wouldn't last against Duel Academy, but Declan revealed that they were instead going to the [[Synchro Dimension]] to recruit allies in their fight against Duel Academy. Shay was angry that they weren't taking the fight directly to Duel Academy and wanted to go there by himself, but Celina claimed that it would be suicidal for him to do so, and reassured Shay that Lulu would be as well-treated there as Celina herself had been. Shay was still angry at Yuya for taking Yuto's "Dark Rebellion Xyz Dragon" card, but Yuto communicated to Shay from within Yuya. He told him that Yuya was an ally that they could depend on and trust. When Shay snapped back to reality, Yuya asked him what was wrong and the former replied it was nothing. Declan explained to the group that he'd upgraded their [[Duel Disk]]s to travel across dimensions and produce an Action Field, and they departed for the Synchro Dimension.<ref name="ep53">{{episode|Yu-Gi-Oh! ARC-V|53|ref}}</ref>

[[File:Shay vs Hunter Pace.png|thumb|Shay wins against [[Hunter Pace (ARC-V)|Hunter Pace]].]]
Shay arrived alone in the Synchro Dimension's [[New Domino City (ARC-V)|New Domino City]], assuming that everyone else had been trapped between dimensions. He heard rumors of an [[Underground Dueling Arena]] where [[Duelist]]s Dueled with their all and managed to gain access to it with the intention to recruit more allies. Finding the Duelists to be below his expectations, Shay quickly became a crowd favorite, defeating nine Duelists in a row, including [[Hunter Pace (ARC-V)|Hunter Pace]] in [[Turbo Duel]]s. [[Dennis McField|Dennis]] and Gong arrived, having been picked up by the arena's owner [[Lucas Swank]], and Shay explained his intention to win his way into the [[Friendship Cup]] and Duel the Duel King, [[Jack Atlas (ARC-V)|Jack Atlas]].<ref name="ep58">{{episode|Yu-Gi-Oh! ARC-V|58|ref}}</ref>

[[File:Shay and Dennis.png|thumb|left|Shay in a [[Turbo Duel]] against [[Dennis McField|Dennis]].]]
Lucas ended up pitting Shay against Dennis in a Turbo Duel after the two directed mild barbs at one another. Since it was his tenth game in his winning streak, Shay was handicapped with a 1000 [[LP]] start, but he swiftly inflicted damage to Dennis. Dennis was able to prevent game ending damage and Shay did the same, using "[[Rank-Up-Magic Raid Force (anime)|Rank-Up-Magic Raid Force]]" to call out "[[Raidraptor - Blaze Falcon (anime)|Blaze Falcon]]" and nearly defeat Dennis. He was surprised at the intensity of Dennis's Dueling, given that Dennis was an LID student and grew suspicious. Dennis responded that he was indeed from LID and performed a Pendulum Summon on his next turn.<ref name="ep58" /> Dennis performed a Pendulum-Xyz Summon to bring out "[[Performage Shadow Maker]]" and destroy "Blaze Falcon", but Shay avoided damage and brought out "[[Raidraptor - Revolution Falcon (anime)|Revolution Falcon]]" using "Revolution Force". Despite this, Dennis was able to Summon another "Shadow Maker" using the effect of the first one. Before the Duel could end, however, their [[Duel Runner]]s were deactivated and they were sent tumbling, and were then arrested by [[Sector Security (ARC-V)|Sector Security]].<ref name="ep59"/>

[[File:Gong, Shay, Dennis arrested.png|thumb|Shay, [[Gong Strong|Gong]] and Dennis are arrested by [[Sector Security (ARC-V)|Sector Security]].]]
Upon arriving at the [[Facility (ARC-V)|Facility]], Shay got into a fight with ten other prisoners and was sent to solitary confinement as a result.<ref name="ep60">{{episode|Yu-Gi-Oh! ARC-V|60|ref}}</ref> He heard the cheering during Yuya's Duel with the prisoner "boss", [[Chojiro Tokumatsu]].<ref name="ep61">{{episode|Yu-Gi-Oh! ARC-V|61|ref}}</ref> Later, Shay resolved to break out of the Facility by himself. He climbed to the ceiling of the cell to trick the guards into coming in to look for him. As soon as they did, Shay broke out into the hallways and knocked the guards out with ease. He ran into Gong, who was part of a larger-scale breakout and had come to break Shay out himself. Shay claimed that he didn't need Gong, but he led him to a storage room to reclaim theirs and Dennis' Duel Disks, refusing to leave while unarmed.<ref name="ep62">{{episode|Yu-Gi-Oh! ARC-V|62|ref}}</ref> He intervened when Gong failed to save Yuya, Sylvio, and Chojiro from the [[Stomptroopers]]. He took advantage of the lack of [[Level]] of "Rise Falcon" to bypass the effect of the troopers' "[[Goyo King (anime)|Goyo King]]" and defeat them. They regrouped with the rest of the escaped Lancers in addition to fellow escapees [[Crow Hogan (ARC-V)|Crow]], [[Shinji Weber|Shinji]], and [[Damon Lopez|Damon]], but when they attempted to swim from the Facility, they were arrested personally by Sector Security Director [[Jean Michel Roget]]. Envoys of the [[High Council]] intervened on their behalf, and the Lancers were inducted into the Friendship Cup, with Shay set up to Duel against Dennis on the second day of the tournament in the first round.<ref name="ep70"/><ref name="ep63">{{episode|Yu-Gi-Oh! ARC-V|63|ref}}</ref>

Shay Dueled Dennis again in the final Duel of the second day of the Friendship Cup. Suspecting that Dennis was an agent of Duel Academy, he vowed to prove it during their Duel. Shay started off much the same as their previous Duel, using "[[Raidraptor - Fiend Eagle (anime)|Raidraptor - Fiend Eagle]]" to inflict early damage to Dennis. Dennis called out four Xyz Monsters, "[[Performage Trapeze Magician (anime)|Performage Trapeze Magician]]" and three "Peformage Shadow Makers", but Shay defended with "Revolution Falcon" and used "[[Raidraptor - Target Flag]]" in an attempt to force Dennis to reveal his hand upon the destruction of "Trapeze Magician". He was able to break through Dennis's defense, accusing him of using tactics that weren't taught at LID, and he destroyed "Trapeze Magician". Dennis grimly revealed the card in his hand - "[[Polymerization (anime)|Polymerization]]", revealing that he was indeed from Duel Academy when he performed a [[Fusion Summon]] to Summon "[[Chaos Ancient Gear Giant (anime)|Chaos Ancient Gear Giant]]". Remembering the monster from the attack on Heartland, Shay faced the now darkly talking Dennis, refusing to allow the monster to rampage again.<ref name="ep74" />

After learning about Lulu's kidnapping from Dennis, Shay became more enraged and Summoned his strongest monster, "[[Raidraptor - Satellite Cannon Falcon (anime)|Raidraptor - Satellite Cannon Falcon]]". He used it to defeat Dennis mercilessly, leaving him injured. After the Duel, Shay angrily approached Dennis and attempted to seal him into a card but he realized he couldn't do that, speculating that Declan removed that function from his Duel Disk. Shay attempted to punch Dennis instead, but he was quickly restrained and taken away by the stadium's security.<ref name="ep75"/>

===Friendship Cup Finals===
[[File:Shay saves Tanner.jpg|thumb|left|Shay saves [[Tarren]] during his Duel against [[Crow Hogan (ARC-V)|Crow]].]]
Shay watched the Duel between Zuzu and [[Sergey Volkov]] and he was extremely shocked after witnessing Zuzu's brutal defeat.<ref name="ep77">{{episode|Yu-Gi-Oh! ARC-V|77|ref}}</ref> Shay later watched the Duel between Yuya and Shinji.<ref name="ep78">{{episode|Yu-Gi-Oh! ARC-V|78|ref}}</ref> He was set to Duel against Crow Hogan for his second Duel, and he theorized that Duel Academy might have more agents in the Synchro Dimension, vowing to expose them.<ref name="ep80">{{episode|Yu-Gi-Oh! ARC-V|80|ref}}</ref> Uncaring of the controversy between the [[Topsiders]] and the Commons, Shay warned Crow before the Duel that he wouldn't show him mercy if he was from Duel Academy. Crow's "[[Blackwing]]s" traded blows with "Raidraptor - Rise Falcon" evenly, but despite losing a large portion of his LP, Shay was able to protect "Rise Falcon" and Rank-Up his monster to bring out "Raidraptor - Blaze Falcon" to destroy Crow's own ace monster, "[[Assault Blackwing - Raikiri the Rain Shower (anime)|Assault Blackwing - Raikiri the Rain Shower]]". Shay affirmed during the Duel that he didn't consider the other Lancers to be his comrades and that the loss of his comrades from the Xyz Dimension had caused him to view everyone else as an enemy and everything as a battlefield.<ref name="ep81">{{episode|Yu-Gi-Oh! ARC-V|81|ref}}</ref> He urged Crow to come at him, and Crow delivered, resurrecting "Raikiri" through [[Phantom Synchro]] and preventing Shay from getting an Action Card. Shay noticed that [[Tarren]] was clinging onto the back of "Raikiri", having been dislodged from his watching position and attempted to stop the Duel, but Crow refused and destroyed "Blaze Falcon". Shay used "Raptor's Force" to bring out "Revolution Falcon" and managed to get Crow to notice Tarren. Tarren was dislodged and Shay managed to catch him on "Revolution Falcon". He explained to Tarren that he had previously had children that cheered for him as well before returning Tarren to Zuzu, [[Frank (ARC-V)|Frank]], and [[Amanda]]. Crow thanked Shay, and Shay thanked Crow as well; as seeing Crow and the children had reminded him that he was fighting for the children of Heartland, before discussing his similarities with Crow. Shay brought out "Satellite Cannon Falcon" on his next turn with "[[Rank-Up-Magic Skip Force (anime)|Rank-Up-Magic Skip Force]]" and then reused "Skip Force" in order to call out "[[Raidraptor - Ultimate Falcon (anime)|Raidraptor - Ultimate Falcon]]". Crow was barely able to survive the turn and countered with a flurry of Synchro Summons on his next turn to bring out "[[Assault Blackwing - Onimaru the Divine Thunder (anime)|Assault Blackwing - Onimaru the Divine Thunder]]", which defeated "Ultimate Falcon" and Shay with it; Shay smiling as he was defeated. Before going to the underground, Shay and Crow told one another to continue fighting their enemies, and they parted as comrades.<ref name="ep82">{{episode|Yu-Gi-Oh! ARC-V|82|ref}}</ref> Amanda, Frank, Tarren, and Zuzu later discovered that Shay had gone to the Underground Labor Facility when they took refuge there themselves.<ref name="ep87">{{episode|Yu-Gi-Oh! ARC-V|87|ref}}</ref>

Shay was doing cleanup work until Crow came down and explained that Duel Academy had invaded New Domino City. He started fighting the guards until they restrained him, but was saved by Moon Shadow. Shay, Gong, and Sylvio then got their [[Duel Disk]]s from Moon Shadow, who also informed that Riley was Dueling alone to protect Celina. Shay and Sylvio decided to go help while Gong stayed to protect Zuzu from Sector Security. Their escape route was blocked off by an electric gate, forcing them to Duel against five guards, who were all defeated by Shay's "[[Raidraptor - Blaze Falcon (anime)|Raidraptor - Blaze Falcon]]". Lucas then came on a mining cart to capture them but crashed into the electric gate. The Stomptroopers arrived and surrounded them but were stopped when Shinji activated the conveyor belt. Lucas returned to Duel them but was attacked by [[Officer 227]] and his fellow former officers, allowing Shay, Sylvio, and Moon Shadow to escape; Shay exchanging a fist bump with Crow from far away.<ref name="ep90">{{episode|Yu-Gi-Oh! ARC-V|90|ref}}</ref>

[[File:Shay Flys In With Raidraptors.png|thumb|Shay flies in with his "[[Raidraptor]]s" to take [[Yuya Sakaki|Yuya]] to the [[Duel Palace]] to Duel [[Jack Atlas (ARC-V)|Jack]].]]
Shay worked alone again, jumping on and off a boat to cross a river and get to the other side of a district, while wondering about the whereabouts of the Obelisk Force.<ref name="ep91">{{episode|Yu-Gi-Oh! ARC-V|91|ref}}</ref> As the rioting continued he was running around and muttering about the whereabouts of Duel Academy, unaware that they had already been defeated by Yuya, Riley, Sora, Moon Shadow, and Sergey, and that they retreated back to the Fusion Dimension.<ref name="ep93">{{episode|Yu-Gi-Oh! ARC-V|93|ref}}</ref> He found and rescued Riley from rioting Commons and accompanied him, Sylvio, and Chojiro to the Capital Building where they were joined by Declan. Declan asked Shay to have his "Raidraptors" to fly them to the [[Duel Palace]] and rescue Yuya, as Declan had predicted that this was where Yuya would have gone. They picked Yuya, Gong, [[Sam (ARC-V)|Sam]], Frank, Amanda and Tarren up from the bridge to the Duel Palace and brought them inside, where Yuya chAlanged Jack Atlas to a Duel.<ref name="ep95">{{episode|Yu-Gi-Oh! ARC-V|95|ref}}</ref> Shay helped the Lancers and Chojiro in fending off Sector Security when they stormed the Duel Palace, tearing all of their enemies with "Raidraptor - Rise Falcon".<ref name="ep96">{{episode|Yu-Gi-Oh! ARC-V|96|ref}}</ref> During the Duel after Yuya managed to withstand the attack of Jack's "[[Scarlight Red Dragon Archfiend (anime)|Scarlight Red Dragon Archfiend]]", Shay remarked that it was too soon to be at ease. He later went out with the Lancers to quell the Commons' riots, seeking out Crow and intervening in Crow's face-off with [[Shinji Weber]].<ref name="ep97">{{episode|Yu-Gi-Oh! ARC-V|97|ref}}</ref>

[[File:LancersLookOverHeartland.png|thumb|left|Shay over look Heartland.]]
Shay succeeded in resolving Crow and Shinji's issues, as they both left Shay and got on their Duel Runners to show their support for Yuya's Duel against Jack. Shay watched the remainder of the Duel and smiled when Yuya won. Shay also watched Sora's broadcast and was shocked to learn that [[Jean Michel Roget]] defeated Sora and Moon Shadow. He quickly left before the broadcast ended, heading towards Sector Security Headquarters to join the efforts in rescuing Zuzu from Roget.<ref name="ep98">{{episode|Yu-Gi-Oh! ARC-V|98|ref}}</ref> He broke into the building with "Rise Falcon" and found Gong and Sylvio at the control room where Sora had sent his message. Shay commented that Sora was likely still alive. After Yuya rescued Zuzu, Shay was the first to notice that Roget was still alive. Roget activated the Interdimensional Transportation Machine, which teleported himself and Zuzu to an unknown dimension. When Gong tried to prevent Yuya from being sucked into the wormhole too, Shay came to his aid and Sylvio to his, but they were all sucked into the wormhole and ended up in the ruins of a city. Shay informed the others that this was [[Heartland City (ARC-V)|Heartland City]] in the [[Xyz Dimension]].<ref name="ep99">{{episode|Yu-Gi-Oh! ARC-V|99|ref}}</ref>

===Heartland City===
After informing the Lancers where they were, Shay separated from them to check on the Resistance base, but he found it abandoned and concluded that this comrades had been wiped out in his absence. He left the building and lamented that he'd thought that allying with Declan would be a shortcut to Lulu, remembering both when he'd first found out about Declan and their first meeting.<ref name="ep100"/>

[[File:ShayArrivesWithComrades.png|thumb|Shay arriving with Alan and Saya.]]
While Yuya and [[Kite Tenjo (ARC-V)|Kite]] were Dueling and Kite mistook Yuya for Yuto, Shay, [[Alan]], and [[Saya Sasayama|Saya]] arrived and cleared up the misunderstanding. He revealed that Yuya, Sylvio and Gong were his comrades but Kite still doubted him. Shay assured Kite that Yuya wanted to stop Duel Academy as much as they did, asking him to trust Yuya like he did. However Kite refused before disappearing in a flash of light after hearing Yuya's last name.<ref name="ep102">{{episode|Yu-Gi-Oh! ARC-V|102|ref}}</ref>

At the Resistance's [[Duel Sanctuary (ARC-V)|new hideout]], Shay revealed that they were able to find Yuya and the others because the refugees that they had saved before told their location and gave them their gratitude. Alan then suspected that Yuya was in fact Yuto himself due to their great resemblance and even using "[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion Xyz Dragon]]", but Shay cleared the confusion, explaining that despite their resemblance Yuya is not Yuto and the latter had suddenly vanished. He furthered explained that he originally thought Yuya had stolen "Dark Rebellion" from Yuto, however, after watching Yuya throughout their battle at [[Synchro Dimension]], he dismissed his suspicion as he now understood why Yuto entrusted "Dark Rebellion" to Yuya. Alan then explained that while they were gone, Duel Academy had launched a massive offensive attack that almost completely destroyed both [[Spade Branch|Spade]] and [[Clover Branch|Clover branch]]s' Resistance Duelists, including Kite's family. Shay blamed himself for this, thinking that if he and Yuto were there, they might be able to do something to change the situation.<ref name="ep103" />

[[File:ArcV 105.png|thumb|left|Shay attempting to bring Kite back to the Resistance.]]
Shay appeared to Kite after the latter shrugged off Alan and Saya's attempt to bring him back. He grabbed Kite's shoulder, prompting Kite to lunge away and threaten to turn Shay into a card as well. Shay told him to go ahead and try and the two started a Duel. Shay Summoned "[[Raidraptor - Rise Falcon (anime)|Raidraptor - Rise Falcon]]" on his first turn, a move Kite called a disgraceful misplay, as that monster's effect requires the opponent to control a [[Special Summon]]ed monster to be used. Shay was able to counter the effect of Kite's "[[Galaxy-Eyes Cipher Dragon (anime)|Galaxy-Eyes Cipher Dragon]]" with "[[Raptor's Intercept Formation]]" and mitigate some of the impact of that attack with an [[Action Card]], "[[Miracle]]". Kite claimed Shay was a coward. Shay brought out "[[Raidraptor - Blaze Falcon (anime)|Raidraptor - Blaze Falcon]]" and destroyed "Cipher Dragon", but Kite used "[[Cipher Spectrum (anime)|Cipher Spectrum]]" to revive it and Special Summon a second one. Yuya arrived and asked them to stop the fight, as they were comrades. Kite claimed that "Cipher Dragon" was a part of him and that he no longer needed comrades. Shay used a string of Action Cards in an attempt to take down "Cipher Dragon" but failed and brought out "[[Raidraptor - Ultimate Falcon (anime)|Raidraptor - Ultimate Falcon]]". Kite chided him for claiming the Action Cards represented his new comrades and that the move failing must mean his comrades will fail too. When Yuya began talking about Kite and Shay's past and revealed that Yuto resided inside of him, Shay claimed he had had a hunch about that. Though "Ultimate Falcon" nearly won Shay the Duel, "[[Cipher Mirror Knight]]" and "[[Cipher Clone Magic]]" enabled Kite to come back and defeat it and Shay. Kite moved to turn Shay into a card after the Duel, but stopped to reconsider after Saya pleaded with him. Having already lost [[Lulu Obsidian|Lulu]], Saya said she couldn't bear to lose Shay as well. Kite still seemed to be consider turning him into a card, but reluctantly stopped and proceeded to walk away.<ref name="ep105" />

Shay returned to the hideout and decided to split the Lancers into two groups to find Saya. He told Gong and Sylvio not to slack off.<ref name="ep107">{{episode|Yu-Gi-Oh! ARC-V|107|ref}}</ref> While searching, Shay and Yuya heard Sylvio's scream and ran to his location. They arrived and found Sylvio, Gong, Alan, and Saya on the ground. Shay was surprised when Gong whispered, "[[Amazoness]]". He then asked the [[Gloria Tyler|female]] [[Grace Tyler|Duelists]] if were they the ones who used "Amazoness" [[Main Deck|Decks]]. The sisters thought Shay was a Resistance member who fled, and Shay was about to respond until Yuto cut in via Yuya. Shay asked Yuya to let Yuto do what he wanted because Yuto must be feeling the same way as Shay was. Yuya agreed under the condition that he could Duel his own way; Shay replied that Yuya could do what he wanted, as Shay would Duel his own way. They Dueled the Tyler Sisters in a [[Tag-Team Duel]] and learned that the Professor had sent the Tyler sisters after them; Shay noted defeating them would thus be all the sweeter. On Shay's turn, Shay told the Tyler sisters that he would show them how the Resistance retaliated when cornered. He Pendulum-Xyz Summoned "Raidraptor - Rise Falcon" and attacked both "[[Amazoness Pet Liger (anime)|Amazoness Pet Liger]]" and "[[Amazoness Empress (anime)|Amazoness Empress]]", but was unable to destroy them due to their effects and furiously watched as the Tyler sisters regained their lost LP with "[[Amazoness Hot Spring (anime)|Amazoness Hot Spring]]". Shay was able to use "[[Rank-Up-Magic Escape Force]]" and "[[Raidraptor - Iron Heart]]" to dodge the attack by Ranking-Up "Rise Falcon" into "Blaze Falcon" and then reviving "Rise Falcon". Grace told Shay to give up, Shay told them that the Resistance didn't know those words and he vowed that he would never give up. Yuya asked Shay and Yuto to let him answer their feelings, and Shay eventually agreed. Shay heard Yuya telling Yuto that he would borrow their strength and helped him by using the effect of "Rise Falcon". He then smiled as he and Yuya won the Duel.<ref name="ep108">{{episode|Yu-Gi-Oh! ARC-V|108|ref}}</ref>

[[File:Saya, Shay, and Kite.png|thumb|An unconscious Shay being carried by [[Kite Tenjo (ARC-V)|Kite]].]]
After the Duel, Shay told Alan to be himself when he accepted Yuya as a comrade before the Obelisk Force arrived. He and Yuya decided to Duel them since the others were injured. Shay told Yuya that his Dueltaining wouldn't work on them, but he would still Duel his own way. Shay brought out "Rise Falcon", but it was destroyed by the effect of "[[Double Ancient Gear Hunting Hound]]". Shay used "[[Rank-Up-Magic Raptor's Force (anime)|Rank-Up-Magic Raptor's Force]] to summon "Blaze Falcon" and gain advantage. When Yuya was targeted by the effect of "[[Ancient Gear Hunting Hound (later anime)|Ancient Gear Hunting Hound]]", Shay activated "[[Raidraptor - Silent Roar]]" to negate it. After the Obelisk Force brought out "[[Chaos Ancient Gear Giant (anime)|Chaos Ancient Gear Giant]]", Shay ran to save Saya from the falling debris caused by the shockwaves created by "Chaos Giant". He was able save Saya but he was badly injured by the debris and he collapsed from his wounds.<ref name="ep109">{{episode|Yu-Gi-Oh! ARC-V|109|ref}}</ref> After Kite defeated the squad [[Aster Phoenix (ARC-V)|Aster Phoenix]] bought with him, he carried Shay on his back and escaped with the others, while Yuya Dueled Aster.<ref name="ep110">{{episode|Yu-Gi-Oh! ARC-V|110|ref}}</ref>

[[File:Shay Place in a Recover Pod.png|thumb|left|Shay placed in a recovery pod.]]
Shay was safely taken back to the Resistance hideout and resting there with Saya, Sylvio, and Gong watching over him. The Duel Academy in Heartland decided to abandon the [[Arc Project]] and help rebuild the [[Xyz Dimension]] to atone for what they have done. Shay was relocated to Duel Academy's base in Heartland for more proper medication under Aster's suggestion, being placed in a healing capsule until he recovered. Kite then took his place to rescue Lulu.<ref name="ep112">{{episode|Yu-Gi-Oh! ARC-V|112|ref}}</ref>

Shay recovered from his injuries and he and Aster traveled to Duel Academy. He arrived in time to see Kite falling off of the Western tower, and sent "Rise Falcon" to save him. He told Kite how Aster helped him and decided to come when finding out that the Lancers were going to Duel Academy. He learned from Kite that Lulu pushed him off the tower and ran up the tower to see her.<ref name="ep117">{{episode|Yu-Gi-Oh! ARC-V|117|ref}}</ref> He made it to the top of the tower and saw Lulu. They hugged each other after being reunited until Kite arrived. Shay and Kite argued about Lulu's sanity until she tried to attack Shay. Upon seeing this, Shay refused to forgive Duel Academy and accepted her chAlange. Before the Duel, Kite gave Shay Saya's "[[Little Fairy (later anime)|Little Fairy]]". Shay Xyz Summoned "Rise Falcon" on the first turn, and upon seeing Lulu Summon "[[Lyrilusc - Assembled Nightingale (anime)|Lyrilusc - Assembled Nightingale]]", Shay was positive that it was Lulu, but she had fAlan into the darkness. Shay told Lulu that he would bring Lulu back to her true self and he brought out "Blaze Falcon" to reduce the Overlay Units of "Assembled Nightingale". Lulu attacked Shay again on her next turn, and Shay commented that it was sweet that Lulu was still using the same Deck despite being under Duel Academy's control and he claimed that she couldn't defeat him due to being familiar with it. However, Lulu Summoned a new monster, "[[Fusion Parasite (anime)|Fusion Parasite]]", and used it to [[Fusion Summon]] "[[Lyrilusc - Independent Nightingale (anime)|Lyrilusc - Independent Nightingale]]", much to Shay's shock. He deduced that "Fusion Parasite" was controlling Lulu since she would never use Fusion and fended off Lulu's efforts to defeat him. Shay asked if Lulu remembered her Duel with Saya in the Clover Branch tournament. He told her how he didn't understand Saya's behavior, even after losing Lulu. But after meeting Yuya and the Lancers, he understood and he Summoned "Little Fairy" and used its effect twice to increase its Level to 5 before combining it with "Blaze Falcon" via "[[Cross Xyz]]" to [[Cross Xyz Summon]] "[[Raidraptor - Stranger Falcon (anime)|Raidraptor - Stranger Falcon]]". He told Lulu that Saya, Kite, and all of their comrades were waiting for her return, but she claimed that she didn't care. He activated the effect of "Stranger Falcon" to destroy "Independent Nightingale" and inflict damage equal to its ATK. Lulu regained control of her body and told Shay to attack her. "Stranger Falcon" did so, winning Shay the Duel, and Shay ran to check on Lulu.<ref name="ep119" />

[[File:Lulu Awakes To Shay.png|thumb|Shay greets his sister after her rest while taking her down the tower.]]
As Shay made it to the bottom of the tower with Lulu on his back, he collapsed. He held his shoulder while Lulu ran off to go find Kite for help.<ref name="ep122">{{episode|Yu-Gi-Oh! ARC-V|122|ref}}</ref> When Yuya and Yuto vowed to regain Lulu's sanity by destroying "Independent Nightingale", Shay told them it was useless. He told Yuya how he already Dueled Lulu and destroyed "Fusion Parasite" but the result ended the same and they probably have to defeat [[The Doktor|the person]] controlling her. He was surprised to see Yuya using Yuto's Deck and was happy when he Xyz Summoned "[[The Phantom Knights of Cursed Javelin (anime)|The Phantom Knights of Cursed Javelin]]". Shay then told Yuya that he was leaving Lulu to him while he looked for the person controlling her but was tased by Celina.<ref name="ep124"/> Shay muttered Lulu's name and told Yuya to go after her and Celina, passing out in the process.<ref name="ep125">{{episode|Yu-Gi-Oh!

===Duel Academy===
[[Kite Tenjo (ARC-V)|Kite]] found Shay in [[the Doktor]]'s lab, and Shay informed Kite that the Doktor had brainwashed [[Lulu Obsidian|Lulu]]. [[Aster Phoenix (ARC-V)|Aster]] arrived as well, and Shay told him and Kite to go after [[Yuya Sakaki|Yuya]], who was following Lulu and [[Celina]].<ref name="ep126">{{episode|Yu-Gi-Oh! ARC-V|126|ref}}</ref> Shay wondered what was happening when he saw the world distorting around him, and he came across Kite again and asked him what had happened to their comrades.<ref name="ep135">{{episode|Yu-Gi-Oh! ARC-V|135|ref}}</ref> They made it outside [[Duel Academy (ARC-V)|Duel Academy]] to see the dimension fractured and ominous fog coming from the [[City (Fusion Dimension)|City]], causing Shay to wonder what was happening. They saw [[Sora Perse|Sora]] and Aster Dueling through a dimensional rift, and Shay wondered who were they Dueling. He was shocked to see that they appeared to be Dueling Yuya, but Kite explained that they must be Dueling [[Z-ARC]], and he noted that Z-ARC must have been revived. Shay realized that Z-ARC was the being that had been formed from Yuya, [[Yuto]], [[Yugo]] and Yuri]], and they moved to assist Sora and Aster. After Z-ARC fused with the "[[Supreme King Z-ARC (anime)|Supreme King Z-ARC]]", Shay and Kite arrived and joined the Duel and both received intrusion penalties as Shay's Duel Disk turning the Duel into an [[Action Duel]]. Z-ARC defeated Sora and Aster, and Shay ran to check on Sora, who lamented his failure to reach Yuya and gave [[Yuya's pendant]] to Shay. Shay promised to return Yuya to normal, and he and Kite then prepared to take on Z-ARC. Shay declared that Z-ARC's form didn't suit him and vowed to return Yuya and Yuto to normal.<ref name="ep136">{{episode|Yu-Gi-Oh! ARC-V|136|ref}}</ref>

Shay looked at Yuya's pendant, noting that Sora and Aster had believed in and fought for Yuya's heart. Kite declared that they would inherit that belief, and Shay agreed that they would bring Yuya and Yuto back. He quickly [[Xyz Summon]]ed "[[Raidraptor - Rise Falcon (anime)|Raidraptor - Rise Falcon]]" and flew up to meet Z-ARC, but to his surprise this allowed Z-ARC to Xyz Summon "[[Supreme King Dragon Dark Rebellion (anime)|Supreme King Dragon Dark Rebellion]]" during his turn, though the appearance of his friend's corrupted ace monster caused Shay to believe that Yuto was still present within Z-ARC. As he activated the effect of "Rise Falcon", he asked Yuto if he remembered restraining Shay in the [[Standard Dimension]], vowing to do the same for Yuto and begging him and Yuya to wake up. Z-ARC countered with the effect of "Dark Rebellion", forcing Shay to remove "Rise Falcon's" Overlay Units via "[[Overlay Burst Armor]]" to protect it. Kite noted that he and Shay could reach Yuya and Yuto through their Dueling, though Shay reminded him that the effect of "Dark Rebellion" was in the way. Shay was surprised to see [[Alan]] and [[Saya Sasayama|Saya]] on a nearby rock, wondering how they had been transported to the Fusion Dimension. Z-ARC attacked "Cipher Dragon", Shay told Alan not to panic and used "[[Rank-Up-Magic Devotion Force]]" to [[Rank-Up]] "Rise Falcon" into "[[Raidraptor - Blaze Falcon (anime)|Raidraptor - Blaze Falcon]]". In response, Kite used "[[Rank-Up-Magic Limit Over Force]]" to [[Xyz Evolution#Rank-Up Xyz Evolution|Rank-Up Xyz Evolution]] "[[Neo Galaxy-Eyes Cipher Dragon (anime)|Neo Galaxy-Eyes Cipher Dragon]]", and Shay used his own "Limit Over Force" to Rank-Up "Blaze Falcon" into "[[Raidraptor - Revolution Falcon (anime)|Raidraptor - Revolution Falcon]]" and multiply its ATK by the number of "Rank-Up-Magic" cards they had. He begged Yuto to listen to his voice, but Z-ARC used the effect of "Dark Rebellion" to return it to his Extra Deck and Special Summon two "[[Supreme King Dragon Darkwurm (anime)|Supreme King Dragon Darkwurm]]s" to reduce the ATK of their monsters to 0. Shay and Kite used [[Action Card]]s when Z-ARC attacked them, but the effect of "Supreme King Z-ARC" destroying them as they had been added to their hands outside the [[Draw Phase]]. Shay and Kite were defeated and blasted through the air, but they were fortunately caught by [[Gong Strong|Gong]], who had joined the Duel with [[Jack Atlas (ARC-V)|Jack]] before their defeat. Shay apologized to Sora for his failure and told Gong that it was up to him and gave him Yuya's pendant.<ref name="ep137">{{episode|Yu-Gi-Oh! ARC-V|137|ref}}</ref>

Shay realized that Z-ARC planed to [[Synchro Summon]] during Jack's turn after Z-ARC told Jack that he had already lost by Synchro Summoning. Jack and Z-ARC countered one another's attacks, and Shay wondered what else Jack could do this turn. To his surprise, Jack and Gong were able to get Z-ARC to react to [[Dueltainer|Dueltaining]]. He was also surprised when [[New Domino City (ARC-V)|New Domino City]] materialized in the Fusion Dimension. To Shay's shock, [[Crow Hogan (ARC-V)|Crow]] joined the Duel alongside [[Sylvio Sawatari|Sylvio]], having been freed from the [[Crow Hogan (ARC-V card)|card]] that he had been sealed in.<ref name="ep138">{{episode|Yu-Gi-Oh! ARC-V|138|ref}}</ref> Shay was surprised that Crow was able to deal damage to Z-ARC and when it appeared that Sylvio had destroyed "Supreme King Z-ARC". To his shock, the [[Fusion Monster|Fusion]] [[Synchro Monster|Synchro]] and [[Xyz Monster]]s in Z-ARC's [[Graveyard]] were preventing it from being destroyed, including Shay's "[[Raidraptor]]s". Shay and Kite were surprised when [[Leo Akaba]] joined the Duel.<ref name="ep139">{{episode|Yu-Gi-Oh! ARC-V|139|ref}}</ref> He and Kite were happy when [[Declan Akaba|Declan]] managed to dealt damage to Z-ARC. However, Shay was worried due to Z-ARC turning the Duel around his way and was surprised when he thought "Z-ARC" killed Declan. He and Kite were pleased when [[Riley Akaba|Riley]] [[En Birds|turned]] all of Z-ARC's Xyz Monsters into [[Normal Monster]]s with their effects negated.<ref name="ep140">{{episode|Yu-Gi-Oh! ARC-V|140|ref}}</ref>

[[File:ArcV 145.png|thumb|Shay about to punch Leo for sacrificing Lulu.]]
Following the battle against Z-ARC, Declan informed Shay of a recreation of the [[Arc League Championship|Junior Arc League Championship]], but Shay didn't care about it and he instead went to the Fusion Dimension to look for Lulu.<ref name="ep144">{{episode|Yu-Gi-Oh! ARC-V|144|ref}}</ref> He approached Leo's chambers, demanding to be let in as [[Alexis Rhodes (ARC-V)|Alexis Rhodes]] tried to calm him down and explain that Leo was trying to revive [[Ray Akaba|Ray]]. Unaware of Ray's identity, Shay ignored her and pounded on the door to Leo's chambers. Sora and Yuya arrived, and Yuya explained that Lulu was Ray's reincarnation as Yuya was of Z-ARC. Shay didn't believe Yuya, incensed at the implication that his memories with his sister were false. Yuya explained that he believed their memories were true and he chAlanged Shay to a Duel. Shay ignored his request, and Sora and Alexis realized that Shay wouldn't believe them, and they agreed to let him in to see Leo. Alexis asked Shay not to disturb Leo, but Shay pushed her aside and angrily asked Leo where Lulu was. Leo explained that Lulu had vanished as Yuto had when Z-ARC's fragments became Yuya, and Shay angrily grabbed Leo's shoulder and prepared to punch him. Leo replied that Shay could hit him all he wanted; he had been so caught up in reviving Ray that he had disregarded the lives of her fragments. Shay lowered his fist and he reflected that having lost Yuto and Lulu, Dueling was all that was left to him, and he accepted Yuya's chAlange. (In the dub, Shay instead transferred his anger to Yuya due to his nature as a fragment of Z-ARC after Leo empathized with him). Shay and Yuya Dueled in the courtyard, and Shay agreed to accept that Lulu was gone if he lost, but ordered Yuya to get out of his sight if Shay won. Shay countered Yuya's [[Action Card]]s with his own, eventually bringing out "Rise Falcon" to destroy "[[Odd-Eyes Pendulum Dragon (anime)|Odd-Eyes Pendulum Dragon]]". Yuya revived "Odd-Eyes" on his next turn and attacked without using "[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion]]" as Shay thought he would, but Shay used "[[Rank-Up-Magic Battle Up Force]]" to [[Rank-Up]] "Rise Falcon" into "Revolution Falcon", activating its effect for a winning blow. However, Yuya survived by lowering the ATK of "Odd-Eyes" with "[[Balance Magician]]", then bringing out "[[Odd-Eyes Lancer Dragon (anime)|Odd-Eyes Lancer Dragon]]" to counter "Revolution Falcon" and destroy it. Shay responded with "[[Rank-Up-Magic Doom Double Force (anime)|Rank-Up-Magic Doom Double Force]]" to Rank-Up "Revolution Falcon" into the [[Rank 12 Monster Cards|Rank 12]] "[[Raidraptor - Final Fortress Falcon (anime)|Raidraptor - Final Fortress Falcon]]". He launched repeated attacks with "Final Fortress Falcon", but Yuya endured the attacks with the effects of "Lancer Dragon" and activated "[[Cross Damage]]" to inflict the damage to both of them for an apparent draw. However, the final effect of "Lancer Dragon" allowed Yuya to survive, defeating Shay, but as Shay lost, he saw Yuya as Yuto. He accepted Yuya's hand up, but denied that Lulu was gone after witnessing Yuto's presence, (in the dub, claiming that if Yuto was still alive within Yuya, then Lulu might be to a degree as well) and Yuya agreed that he would save them. However, Jack then announced that Yuya couldn't save anyone in his current state.<ref name="ep145">{{episode|Yu-Gi-Oh! ARC-V|145|ref}}</ref>

Sora asked Yuya if he was afraid, and Shay agreed that he had felt uncomfortable when Yuya didn't bring out "Dark Rebellion". Jack explained that Yuya feared using the Four Dimensional Dragons because he might reunite with them again. Shay learned that his and Dennis' Duels with Yuya didn't make Riley smile as they had been intended to, and he was surprised when the [[Multiverse Speedway]] activated throughout the [[Four Dimensions]]. Crow brought Yuya his [[Duel Runner]] and Turbo Suit, and Shay watched Yuya and Jack's subsequent [[Turbo Duel]] with Crow, Sora, and Alexis. He was worried when Yuya was pushed into a corner.<ref name="ep146">{{episode|Yu-Gi-Oh! ARC-V|146|ref}}</ref> Shay bumped fists with Crow when Yuya won and watched his Duel with Declan.<ref name="ep147">{{episode|Yu-Gi-Oh! ARC-V|147|ref}}</ref> Shay was surprised when Yuya Fusion Summoned "[[Odd-Eyes Venom Dragon (anime)|Odd-Eyes Venom Dragon]] and when Yuya destroyed "[[Odd-Eyes Wing Dragon (anime)|Odd-Eyes Wing Dragon]]" on purpose to Xyz Summon "[[Odd-Eyes Rebellion Dragon (anime)|Odd-Eyes Rebellion Dragon]]". Shay was also shocked when he thought Yuya defeated Declan and wonder how Yuya would fight when he used the Pendulum Effect of "[[Performapal Five-Rainbow Magician (anime)|Performapal Five-Rainbow Magician]]" to lower their monsters' ATK to 0. He watched Yuya and Declan gather Action Cards to in order for one of them to win the Duel first due to "Five-Rainbow Magician's" effect. Shay was pleased when Yuya won, and he was sent to the [[Standard Dimension|Pendulum Dimension]] by Ray to witness her revival as Zuzu. As he watched, Shay happily realized that Lulu was indeed still alive within Zuzu.<ref name="ep148">{{episode|Yu-Gi-Oh! ARC-V|148|ref}}</ref>

==Relationships==
===Lulu Obsidian===
[[File:Lulu with Yuto and Shay.png|thumb|Shay in a picture with Lulu and Yuto.]]
Shay shows a fierce determination to rescue his [[Lulu Obsidian|younger sister]] and tends to overreact when someone mentions her. This is to the point of threatening his own best friend, [[Yuto]], for stopping him from reaching a potential lead. When he mistook [[Zuzu Boyle|Zuzu]] for Lulu, he was shocked and wondered how she "escaped" and called for her again before fainting when Yuto punched him. When he Dueled [[Dennis McField|Dennis]] and after learning that he was the one who assisted Yuri to kidnap her, he became full of rage and Dueled for her sake, showing how much he deeply loved and cared about her. This is in spite of a slightly rocky relationship as siblings; Shay once yelled at her for losing a Duel and accepting a card from her opponent, Saya.<ref name="ep119" />

===Yuto===
[[Yuto]] and Shay are best friends, although Shay seems to dislike flaunting this fact. They have a strong bond of trust between them, as Shay showed no concern when Yuto Dueled [[Sora Perse]] to save Lulu, trusting Yuto's skill. However, they seem to have contradicting views regarding their methodology as they seem to work separately while in pursuit of the same goal, but seem to remain in contact with each other occasionally. Shay displayed concern when Yuto disappeared after his Duel with [[Yugo]], and later demanded [[Yuya Sakaki|Yuya]] to explain what happened to Yuto and why he had "[[Dark Rebellion Xyz Dragon (anime)|Dark Rebellion Xyz Dragon]]" card. Shay also considers Yuto his 'one and only best friend' as seen during his Duel with Dennis.

===Declan Akaba===
As [[Declan Akaba|Declan]] is the son of his enemy, [[Leo Akaba]], Shay originally saw him as a target and based his attacks on [[Leo Institute of Dueling|LID]] to lure Declan out, capture him and use him as a bargaining chip for Lulu. Realizing that they both see Leo as an enemy, Shay agreed to work with him to form the Lancers. Shay is shown to not fully trust Declan and is frequently annoyed when his demands to take action are refused, forcing him to stay back and watch. Declan often had to request his subordinates to keep Shay under surveillance to ensure he didn't do anything reckless that could affect his plans. In spite of his annoyance, Shay usually relents and follows Declan's instructions, however, he was furious to discover that Declan had sealed the carding function of his Duel Disk permanently in his attempt to get revenge for Lulu and the Xyz Dimension once Dennis was defeated.

===Celina===
Shay was initially surprised to see Lulu's likeness in Celina. He was grateful to Celina for rescuing him from Sora Perse and immediately displayed protectiveness of her from the [[Obelisk Force]]. Celina seems to be the only one in the Lancers who can successfully persuade Shay and keep him in check, discouraging his foolhardy plan to rescue Lulu by himself. Along with Zuzu, Shay informed Celina of Duel Academy's horrifying invasion in the Xyz Dimension and Celina, in turn, assuaged his worries for Lulu and Heartland. The two share similar personalities to the point that Celina is akin to a female version of Shay. In the dub, Shay has claimed that looking at Celina hurts due to her resemblance to Lulu.

===Lancers===
Shay claimed to [[Crow Hogan (ARC-V)|Crow]], during their Duel, that he didn't see any member of the [[Lancers]] as comrades (probably due to Dennis' betrayal). When they were separated during their arrival in the [[Synchro Dimension]], he assumed that they had become lost between dimensions and did not bother to search for them. His perception changes after his Duel with Crow, where he began to consider them as his comrades and repeatedly came to the Lancers' aid during their escape from the [[Facility (ARC-V)|Facility]] and the underground. The Lancers finally earned Shay's complete trust after Yuya's Duel against Jack in the final match, as the Duel and its result made Shay understand that the Lancers, particularly Yuya, also wish to stop Duel Academy and end the war as much as he does. Since then, Shay truly values the Lancers as his allies, which is shown when he asks Kite to trust Yuya and the others like he does.

In the dub, however, after learning that Lulu could potentially be gone forever, Shay transferred his vengeance to Yuya after empathizing with Leo, who had done what he had for [[Ray Akaba|Ray]] as Shay had for Lulu. Shay still considered Yuya his friend, but lashed out at him regardless, believing that his nature as a fragment of Z-ARC had led to Yuto and Lulu's deaths. His rage was only sated after he was defeated, when he sensed Yuto's spirit within Yuya and realized that Lulu could likewise be alive as well.

===Crow Hogan===
[[File:Crow and Shay 1.jpg|thumb|220x|Shay and Crow parted as friends after their Duel.]]
Shay initially saw [[Crow Hogan (ARC-V)|Crow]] as nothing more than another enemy, but their experience with the orphans that Crow looked after and Crow's struggles as a [[Commons (ARC-V)|Commons]] caused him to realize that they had a great deal in common. His demeanor towards Crow changed from that point on, and he genuinely enjoyed the rest of the Duel and smiled when he was defeated. Before parting ways, Shay accepted Crow as a comrade. Crow helped Shay remember what he was fighting for and regained some of the trust lost in the Lancers. Shay's growing friendship with Crow also made Shay open up more to the Lancers and eventually accepted them as his comrades as well.

===Dennis McField===
Shay's relationship with [[Dennis McField|Dennis]] is less than great even before Shay found out his true allegiance. Before their first Duel, Shay commented about Dennis' Xyz being fake and later became suspicious about him as he believed someone from [[LID]] shouldn't be able to Duel the way Dennis did. When Shay found out that Dennis was from Duel Academy and helped in Lulu's capture, his rage reached a zenith. Shay even injured him and tried to seal him in a card. Because of Dennis, Shay lost his trust in the Lancers for a while.

===Kite Tenjo===
[[Kite Tenjo (ARC-V)|Kite]] is Shay's Resistance comrade. Before the invasion, he and Kite were rivals from different school branches and had friendly Duels several times. Shay respected Kite as a fellow Duelist and rival, and later values him as an important comrade after both joined the Resistance. While Kite also feels the same way, even referring to Shay by his first name in the Japanese version, the resulting invasion causes Kite to refuse trusting people from another dimension, even if it's Shay himself telling him that they are his trusted allies, which partly led to Kite distancing himself from Shay and the other Resistance members.

==Deck==
===Raidraptor===
[[File:Shay and Revolution Falcon.png|thumb|Shay and "[[Raidraptor - Revolution Falcon (anime)|Raidraptor - Revolution Falcon]]".]]
Shay runs a '''"[[Raidraptor]]" Deck''', focusing on [[Xyz Summon]]ing using [[Monster Card|monsters]] with the same name. Like [[Yuto]], his Deck also features cards that can [[activate]] in the [[Graveyard]]. He has a considerable edge against multiple opponents due to the powerful [[card effect|effects]] of his [[Raidraptor - Rise Falcon (anime)|ace monster]], which takes advantage of his opponent's [[Special Summon]]ed monsters, reflecting his hatred against [[Fusion Summon]]ing.

His Deck also features "[[Rank-Up-Magic]]" cards, allowing him to perform [[Rank-Up]]s to Summon enhanced versions of his Xyz Monsters that are geared to [[destroy]] and/or deal [[effect damage|damage]] to the opponent through their effects. However since "Rise Falcon" and its upgraded forms suffer from very low [[Original ATK and DEF|original ATK]], Shay supports them with many [[Spell Card|Spell]] and [[Trap Card]]s (including [[Action Card]]s) to prolong their longevity as well as prevent his opponents from protecting themselves when Shay's monsters go on the offensive. His skill with these cards is said to be honed through real combat experience.

Following [[the Resistance]]'s belief that the enemy will likely capture their allies, he includes some cards that allow him to recover control of monsters the opponent steals, such as "[[Rank-Up-Magic Revolution Force (anime)|Rank-Up-Magic Revolution Force]]" and "[[Rescue Xyz]]".

Shay's Deck also features a loop, focusing on Xyz Summoning multiple copies of "[[Raidraptor - Force Strix (anime)|Raidraptor - Force Strix]]", using its searching abilities alongside his "[[Raidraptor - Vanishing Lanius (anime)|Raidraptor - Vanishing Lanius]]" and "[[Raidraptor - Fuzzy Lanius (anime)|Raidraptor - Fuzzy Lanius]]" to quickly overpower his opponent with multiple monsters while maintaining [[hand advantage]].
