Rook is a tall young boy with teal hair in a gear shape with three sideswept bangs at the front and red eyes. He dresses in a rougher fashion than most other characters in the series; he wears a dark brown shirt with a red pattern of a gear on a spoke, beige pants with a black belt, and black slip-on shoes with blue soles and straps. He accessorizes with a collar around his neck similar to that of Yuya Sakaki, a black wristband on his right wrist and a blue strap and a red watch around his left, and a chain hanging from his right pocket. He removes his watch when he Duels to make room to strap on his Duel Disk.
In the past, Rook used various disguises to enter adult Duel Centers, including grey hats, thick brown jackets, and false moustaches.
According to his voice actor, Rook is hot-blooded, but generally a good person. Rook is extremely self-confident, given his proclamation of himself as the strongest Duelist at Goha 7th Elementary. He has a comedic trait of causing machines to break down around him; he claims that this is due to his soul being possessed by the devil. Rook has a habit to jump at what he thinks is cool, and to this end he tries to project a cool and aloof appearance, but he is easily flustered when this is unexpectedly challenged and capable of being excited past this. He tends to act dramatic, with long and complicated Summoning chants and attack names, and often assumes that matters are more complicated than they are; attributing his ability to disable technology to a demon and believing that Yuga let him win their Rush Duel to teach him what he wanted to accomplish with them. He somewhat comically asks if Yuga is sure he wants to relinquish the title of King of Duels, but seizes on the opportunity immediately. Despite his suspicions of Romin Kirishima, when Yuga invites her over to his Road Laboratory he quickly congratulates Yuga.
Rook is quite perceptive, noting when Romin was spying on them and her unusual levels of knowledge of Dueling despite her denial in it. Rook is initially cautious regarding Rush Dueling, as he does not want the Goha Corporation to discover it, but he later comes to accept Yuga's wish to spread Rush Dueling across the world for people to enjoy. Despite this, he is still paranoid that Goha Corp are watching them and that Romin is spying for them. He fiercely defends Rush Dueling when it is insulted, even dismissing insults towards himself.
Rook has a tendancy to make outlandish and ambitious schemes, though these are generally ignored by his friends. He believes himself to be the most important among his friends; this trait is generally played for comedic purposes. Despite his dramatic speeches, Rook has some difficulty with English words.
Similar to Joey Wheeler, Rook has a somewhat "rude" speech pattern, eschewing honorifics. He also deactivates Yuga's Duel Bicycle without his consent to catch his attention and later tries to break into Romin's guitar case as he finds it suspicious, despite Gakuto's protests that doing so would be invading Romin's privacy.
The kanji in Rook's proper name contain the characters for "Upper/Higher", "Castle", "Dragon", and "Eternity/Long time", in reference to his Deck and self-proclaimed status as the number one Duelist of Goha 7th Elementary. His nickname "Rook", a chess piece in the shape of a battlement, is presumably derived from this, in addition to how in Shogi a promoted rook is called "Dragon King".
Rook can cause technology around him to briefly stop working just by touching it. He seems to have developed some level of control over this, but he can only use this ability up to twice a day. Rook himself believes that this is due to his soul being possessed by a demon, but Yuga Ohdo suggests that it may be an example of the Pauli effect.
A year before the events of the series, machines stopped working around Rook. Rook eventually learned to use this ability to his advantage, coming to believe that he was possessed by a demon. He used his power to enter adult Duel centers, practicing his skills against adult opponents and becoming the best Duelist at Goha 7th Elementary. Rook would later claim that he had never lost due to the demon possessing him, though he did lose several times and simply never gave up.
Rook heard about the legend that would allow someone to become the King of Duels. A week before the series, Rook discovered the Hologram Man's underground chamber and challenged him to a Duel. Although Rook was able to defeat the Hologram Man within the time limit, the timer during the Duel continued to run and gave him a penalty when it did. Rook repeatedly tried to pass the trial, but received all six of his penalties and his Duel Disk's account was banned.
Birth of Rush Duels
A week after first finding the Hologram Man, Rook heard fellow student Yuga Ohdo explaining about new Dueling rules to Student Council President Gakuto Sogetsu. Rook was intrigued by the prospect, believing that the new rules could be an interpretation of a line in the legend of the person who would become the King of Duels, and also noticed Romin Kirishima taking photos of them on her smartphone. After school, Rook waited for Yuga outside Goha 7th Elementary and introduced himself, asking if he could have a word. Yuga claimed he was busy and tried to leave, only for Rook to stop his Duel Bicycle with a single touch. Rook told Yuga that he knew somewhere he could install his new rules, and he took him to the Hologram Man's chamber, explaining about the legend on the way. As Yuga worked to install his Rush Duel rules, Gakuto showed up and began berating Yuga, only to freak out at the sight of the Hologram Man, while a Goha Corporation Drone arrived, having detected the violation of the rules. Rook noticed that Romin was there as well and told her to come out, before stopping the Drone from working as he had Yuga's Duel Bicycle. As the kids talked and charged Yuga's Duel Disk using his Duel Bicycle, the Drone eventually began working again, with Rook unable to stop it as he had before, so Romin suggested Yuga use Real-Time Duel Programming. Rook was suspicious of Romin's claims that she wasn't interested in Dueling, and he watched in shock as Yuga decided to use his Rush Dueling to enter the program in time and his Duel Disk transformed. Rook was shocked that Yuga was able to simply Summon three monsters at once, but the Hologram Man Summoned "Blue-Eyes White Dragon" on his first turn, destroyed Yuga's monsters, and reduced him to 1000 LP. Rook and Gakuto both believed that Yuga wouldn't be able to make a comeback against "Blue-Eyes" with a single card, but Yuga revealed that in a Rush Duel, players drew until they had five cards at the beginning of their turns, and he brought out his ace monster, "Sevens Road Magician", managing to increase its ATK high enough to both destroy "Blue-Eyes" and defeat the Hologram Man with one attack. The victory allowed Yuga to successfully install his Rush Dueling rules, and Rook enthusiastically congratulated Yuga. The voice of the Hologram Man congratulated Yuga as well, and Rook wondered if this mean that Yuga was the one in the legend. Rook and Gakuto's Duel Disks suddenly changed shape to become the same as Yuga's, which also deleted Rook and Yuga's penalties, as a path open before them. Yuga told Rook to take the path, but it was simply a hologram and Rook walked right into the dais. Romin and Gakuto asked what the King of Duels was, and Rook explained that they dictated the rules of Duel Monsters. He outlined a scheme to become employed by the Goha Corporation, but Yuga was tinkering with the Drone rather than listening to Rook. Rook asked Yuga to keep Rush Dueling a secret as it had the power to make one of them the King of Duels.
The next day at school, Rook found Yuga and Romin telling their classmates about Rush Dueling, and he promptly dragged Yuga beneath his desk and warned him that they had to keep Rush Dueling a secret from the Goha Corporation to prevent their accounts from being banned. To Rook's surprise, Yuga explained that he wanted to let everyone enjoy Rush Dueling rather than use it for themselves. Romin suggested they settle their argument with a Duel, Rook believed that he'd win no matter the rules used as he was Goha 7th Elementary's strongest Duelist. Before the Duel, Rook disabled everyone's smartphones with his power to keep the Duel secret, though he was deflated when Yuga and Gakuto suggested that his ability was the result of the Pauli effect rather than a demon. Yuga only Summoned a single monster on his first turn, something Rook correctly deduced was due to a bad hand, while Rook aimed to defeat Yuga in a One Turn Kill with his two "Twin-Edge Dragons". Yuga was able to survive, so Rook decided to tell everyone how he had acquired his skills (despite no-one asking). Yuga came close to beating Rook, but failed to get enough monsters in his Graveyard to increase its ATK enough, leaving Rook with 100 LP. Rook promised to finish Yuga off for failing to defeat him and Tribute Summoned "Rush Dragon Dragears", destroyed Yuga's Set card with "Fire Dragon's Heatflash", and destroyed both of his monsters with "Dragears", defeating him. Despite winning, the Duel had been livestreamed by the Drone that Yuga had modified, and Rook angrily asked why Yuga had done it, as Goha Corp would likely delete Rush Dueling. Yuga pointed out how everyone was enjoying it, and told Rook that he'd never stop trying to install Rush Dueling. Rook came to believe that Yuga had let him win the Duel to show him the correct path.
Rook later found that Goha Corp had deleted all of the footage of his Rush Duel, and he deactivated Yuga's Duel Bicycle to tell him the next morning, worried that Goha Corp were observing them. Romin took another picture of them as she suggested they hurry to avoid being late, and Rook decided to look into her, though Gakuto only told him information he already knew. Rook suspected Romin was working for Goha Corp, so Yuga eventually agreed to investigate Romin too, and he tried using one of his Roads to determine if she was hiding something, though they were unsuccessful. Yuga then invited Romin to his Road Laboratory, prompting Rook to congratulate him. At Yuga's lab, they met his modified Drone again, who Yuga named "Kaizo", and Rook was subjected to a hairdressing machine. Yuga convinced Romin to Rush Duel him, and Rook noted her refusal to let Kaizo take her guitar case. As Yuga and Romin Rush Dueled, Rook repeatedly tried to look in the case, but Gakuto held him back to prevent him from invading Rook's privacy. Rook was distracted from his efforts when Romin Tribute Summoned "Prima Guitarna of the Colorful Light", a card that Yuga hadn't put in the spare Deck he had given Romin. Romin stated that it was hers and that she kept it in her guitar case as a good luck charm, reminding Rook of his mission and he opened the case, though he only found Romin's guitar. Romin used the effect of "Prima Guitarna" to increase the ATK of her monsters and destroy Yuga's, including "Sevens Road", putting Yuga in a tough spot, especially when he didn't draw any monsters with enough ATK to beat Romin's. Yuga then used "Recovery Force" to return "Sevens Road Magician" back to his Deck, and Rook was impressed that Yuga was able to draw it again. He defeated Romin by destroying "Prima Guitarna" with "Sevens Road", something Rook noted he didn't have to do to win. Gakuto dragged Rook aside to talk with him after the Duel, and Rook agreed that Romin wasn't working for Goha Corp.
Rook decided to make a promo video for Rush Dueling, with him and Yuga Dueling while Romin provided a backing track and vocals and Gakuto filmed. After Yuga brought Gakuto to the class however, Romin refused to sing and Gakuto left to return to his duties. Despite their difficulties, Rook and Yuga were able to produce a video that satisfied them, though they still wanted to improve the video. They brought a suggestion to Gakuto, but he stated that he would be prohibiting Rush Duels. Yuga instead suggested they settle the matter with a Rush Duel, and Rook leapt on the chance and added that Gakuto would have to step down as Student Councill President if he lost, scheming to succeed him. Gakuto had to postpone the Duel until after school due to his duties, but eventually showed up to Duel Yuga. With Gakuto Dueling, Rook took up the role of explaining the game to Romin over the course of the match. Yuga was eventually able to bypass the effect of Gakuto's "Fiendish Commander Yameruler" by using "Sevens Road Witch" to Special Summon "Sevens Road Magician" and defeat Gakuto, who stepped down as he had agreed. Rook ran against Gakuto in the emergency election, but he was crushingly defeated and Gakuto returned to the position.
Gakuto showed Rook and Yuga that more Rush Dueling videos were being deleted, and Yuga deduced that Goha Corp were likely responsible, so Rook attempted to call Client Service, though he had difficulty communicating with the receptionist. When they arrived at school, they were asked for an interview by the Newspaper Club, so Rook volunteered to tell them about Rush Dueling. Despite Rook's praise for Rush Dueling, the Newspaper Club published an article demeaning them and Rook the next day, much to his fury. They went to have the article changed; Rook telling Masaru and Nico that they could insult him all they wanted, but not Rush Dueling, but didn't make any progress until Yuga threatened to leak the paper to the Goha Corporation, prompting the Newspaper Club's chief, Bakuro Shinjitsu to offer to Duel to decide the article's content, revealing that he had been the one to judge Rush Dueling as simple. Rook accepted the challenge instead of Yuga, vowing to prove that Rush Duels were deep. He gained an early lead over Bakuro, suggesting that he could change the paper to the "Rook Paper", but Bakuro managed to limit the damage he took using Trap Cards. Bakuro was able to bring out three "News Flash Machine Toughroids" and place "Rush Dragon Dragears" on the bottom of Rook's Deck, and Rook barely endured his attacks with "Dragon's Tenacity". This allowed him to shuffle his Deck and draw "Dragears" during his next turn, and he destroyed all of Bakuro's "Toughroids". Bakuro was able to revive one, but Rook Tribute Summoned "Dragears" and used its effect to attack twice, destroying "Toughroid" again and defeating Bakuro. Following the Duel, Yuga revealed he'd believed in Rook the entire time and Bakuro admitted he'd come to enjoy Rush Duels, agreeing to change the article. Having been inspired by their comments about him, Rook requested Bakuro make a picture depciting him ruling over his friends, much to their displeasure.
Rook uses a Dragon Deck, spearheaded by his ace monster "Rush Dragon Dragears". His Deck focuses on aggressive style of play, revolving around destroying his opponent's cards and declaring multiple attacks with his monsters during the same Battle Phase. Several of his Dragon monsters have more varied appearances than normal Dragons.
