Yusaku Fujiki

"Yusaku Fujiki"

- That's right. I am the emissary of revenge. I'll crush the Knights of Hanoi.

Yusaku Fujiki (, Fujiki Yūsaku) is the main protagonist of the Yu-Gi-Oh! VRAINS anime. When Dueling in LINK VRAINS, he is known as Playmaker.

Appearance
Yusaku is a rangy teenage boy with fair skin, green eyes, and dark blue hair that spikes outward in the back and contains light blue bangs with pink accents. His standard attire consists of a slate-colored jacket with light blue trim over a white dress shirt with a blue tie and a pair of black pants and black and white shoes.

While Dueling in LINK VRAINS, Yusaku wears a black and green outfit with a golden stripe going across his body and a grey belt at the waistline. His hair color also changes to yellow and red with pink strips and accents. Occasionally, the golden stripes in his "Playmaker" outfit glow.

When he was a child, Yusaku wore a brown jacket with a green shirt. He wore blue pants, brown boots, and didn't have pink accents on his light blue bangs yet.

Personality
Yusaku may be the first Yu-Gi-Oh protagonist who is an anti-hero. He is not a bad person, but he can appear cold and apathetic. Yusaku is described as a boy who doesn't like standing out at school, not that he's timid or shy but because he is a hacker. Due to a certain incident, he generally tries to avoid contact with others and only seems to trust Shoichi Kusanagi. However, he gets drawn into encounters with people as he tries out Dueling for once.

Yusaku is calm and collected most of the time. Outside of Duels he is shown to be intelligent and clever, but also calculating, standoffish, reserved, and somewhat anti-social. He prefers to distance himself from others and doesn't usually interact with people, not even remembering his classmates' names after a month in school. When Naoki Shima tried to be friendly with him, Yusaku casually admitted to being a loner and inadvertently irritated Naoki with his observations, then didn't react to Naoki storming off. In public, Yusaku comes off as rather awkward and often doesn't know how to answer questions, leading others to assume things about him, such as when Naoki assumed he wanted to join the Duel Club and Aoi assumed he wanted new equipment from SOL. Despite his aloof and calm demeanor Yusaku can be quite sullen when it comes to dealing with Ai's antics.

Despite his introverted and cold nature, Yusaku is both noble and golden-hearted deep down. He is on well terms with his best friend, Shoichi Kusanagi and shows sympathy or care to others' situations like when he discovers that everything Go Onizuka does is for the orphanage, but refuses to let others get close to him and join his fight against Hanoi out of concern that they may get hurt.

As Playmaker he is shown to have a cold and serious demeanor, but at the same time he displays some noble traits to his personality, such as saving Blue Angel when she was about to be attacked by "Cracking Dragon". For currently unknown reasons, Yusaku hates the Knights of Hanoi and swears revenge against them. He didn't hesitate to capture Ai and threatened to delete him in order to challenge the Hanoi. As pointed out by Revolver he has a sense of justice and will help those hurt by the Hanoi. He is also very confident and has lot of faith in his abilities. He is a determined duelist who never gives up.

Unlike most of the previous protagonists, who enjoy Dueling and see it as fun, Yusaku sees Dueling as a tool to eliminate those who are getting in his way. He is also unique in that his motivations for his actions are for revenge, instead of uniting people via Dueling. According to Shoichi Kusanagi, Yusaku doesn't really seem to enjoy Dueling either, as such he tends to reject challenges from other Duelists. That said, when he is either forced to accept a Duel or willingly does so, he will not abandon it, such as when SOL prevented him from logging out when he was forced to Duel Go Onizuka and chose to continue it even when Shoichi made an escape route for him. Furthermore, Yusaku is not above complimenting his opponents, as when he Dueled Onizuka, he claimed that his Duel style, which was meant to excite both the crowd and even his opponent, was first-rate.

He is generally level-headed, serious, aloof and keeps a stoic expression most of the time, though he can give short smiles occasionally. He also doesn't seem to carry animosity towards others, as he stated that he didn't hate Akira for his foul torture, making it clear that he only hates the Knights of Hanoi.

He also has a habit of listing out three reasons for his observations, something he learned from an unknown individual while he was in captivity when he was younger. Yusaku does this to order his thoughts better and clear his mind when confused or feeling discouraged. Oddly enough, Revolver shares this habit.

Abilities
Yusaku is said to be an intelligent hacker who possesses considerable ability and who solves mysteries in a cool manner. It helps him to read a situation and Decode Talker's thoughts.

Cool-headed and extremely clever, Yusaku's real skill is in his hacking and cracking abilities. He was able to hack into SOL Technologies' systems to find Ai, which both SOL and the Knights of Hanoi had been hunting, within a few minutes and in the middle of a security scan, and managed to capture it into his Duel Disk while leaving the AI with no means to escape. He has been fighting the Knights of Hanoi for some time without leaving any trace of his actions as "Playmaker", and keeps a dummy deck to mislead others when in public. Yusaku combines his high intellect with his hacking abilities to quickly come up with plans and think on his feet.

An observant individual, he is good at reading people. When Dueling, Yusaku keeps a close eye on his opponent's body language and expressions to know when they're planning something, and as such, he usually isn't surprised when something unexpected happens.

When in a Speed Duel, Yusaku's Skill is Storm Access which allows him to randomly access a never-before-seen card from a Data Storm when his LP are 1000 or lower, at the cost of having to venture into the Data Storm (it would also appear that the more he uses this Skill, the easier it becomes for him to execute it, as when he used it in his Duels against the Knight of Hanoi and Go Onizuka, he struggled greatly, and had to use his left hand to steady his right arm; however, when he used it in his Duel against Blue Angel, he didn't struggle as much, nor did he steady his right arm). The cards obtained using this ability can then be converted into physical cards outside of LINK VRAINS using appropriate technology; also, as stated by Ghost Girl, "Storm Access" is a unique skill that not just any Duelist can use. He can also teleport back to his D-Board should he fall off from it during a Duel, though he would first need to stop his fall to do so.

Yusaku displays a strange ability to sense and see things in the network world when not logged in called Link Sense. Yusaku has had this ability since a young age. Similar to Ai, he can also discern a Knight of Hanoi's presence through their cards, which allowed him to immediately determine that Go was not a Knight of Hanoi and know when Blue Angel had drawn the card that was affected by Hanoi's influence. He can hear and feel the pulse of his Cyberse monsters.

Etymology
Like the protagonists of the previous five series (Yugi Muto, Jaden Yuki, Yusei Fudo, Yuma Tsukumo, and Yuya Sakaki), his name contains the character「遊」(Yu). In a break from tradition, however, his first name contains three syllables instead of the usual two.

His given name contains the characters "game" (Yu 遊), and "work" (Saku 作). His surname, Fujiki, means "wisteria tree", the blue-and-pink coloring of which matches that of his hair. The kanji of his given name can also be translated as "playing" and "making", which is most likely the pun of his VR name "The Playmaker".

History
Yusaku mentioned the Knights of Hanoi stole his past and some of his memories. Yusaku vaguely remembers being held captive at an unknown facility when he was younger being forced to Duel. After losing a Duel, someone told Yusaku to think of three reasons why he needed to stay alive and win Duels. Ever since Yusaku kept the habit of listing out three reasons for his thoughts, but he never found out who "gave him courage". At some point, he and five other children were found in a forest, presumably after having escaped captivity. He shortly recollected at one point that he most likely surfed the winds in LINK VRAINS before they disappeared. At some point Yusaku began fighting the Knights of Hanoi under the alias "Playmaker" with Shoichi Kusanagi's help. "Playmaker" soon became a famous Duelist within LINK VRAINS, with no one knowing what his real identity is because he always deleted his activity logs.

Yu-Gi-Oh! VRAINS
At school, Yusaku met Naoki Shima, who started bragging to him about his new Duel Disk. When Yusaku attempted to leave, Naoki offered to teach him how to Duel. Yusaku rejected, saying Naoki did not seem very strong, but probably not a bad person either. Yusaku's remarks annoyed Naoki, but he didn't think much of it. Before leaving, he wondered about a rule set where there are only three Main Monster Zones.

Yusaku later met up with Shoichi Kusanagi and discussed how both SOL Technologies and their enemies, the Knights of Hanoi, were chasing after an AI program in LINK VRAINS with him. Upon learning that SOL Technology had scheduled a full scan of Link VRAINS that evening to try and find the AI, they quickly started working on a trap to catch the AI themselves. Although Yusaku successfully captured a reluctant Ai in his Duel Disk, one of the Knights of Hanoi threatened to destroy LINK VRAINS. Yusaku quickly entered LINK VRAINS as Playmaker and saved Blue Angel from the Knight's "Cracking Dragon". He then challenged the Knight to a Duel, putting Ai at stake. Ai voiced his doubts that Yusaku's Deck could beat "Cracking Dragon", then stirred up a wind in Link VRAINS, starting a Speed Duel between Yusaku and the Knight.

As Playmaker rode the Data Storm winds, Ai explained how Speed Duels differ from Master Duels. When Ai mentioned there are only three Main Monster Zones, Yusaku wondered if he already knew about Speed Duels. Ai offered to help Playmaker Duel the Knight, but Playmaker refused, reminding Ai that he was his hostage. The Knight took the first turn and swiftly Summoned "Cracking Dragon". Yusaku wondered how to counter "Cracking Dragon" and failed to notice a building until Ai told him to dodge it, reminding him that Speed Duels have obstacles besides just the Duel. Playmaker summoned "Cyberse Wizard", surprising everyone watching that he had Cyberse monsters. Playmaker used the effect of "Wizard" to change "Cracking Dragon" to Defense Position and inflict damage to the Knight, but failed to destroy "Cracking Dragon". Ai noticed Playmaker wasn't particularly surprised that "Cracking Dragon" couldn't be destroyed, to which Playmaker said that the Knight didn't react to "Cyberse Wizard" so he figured the Knight was planning something. A tornado formed within the Data Storm.

The Knight activated a Skill, which angered Yusaku because Ai didn't mention skills. The Knight used "DDoS Attack" to inflict 1600 Damage to Playmaker and knock him off his D-Board. Blue Angel saved Playmaker by using her whip to throw the D-Board back at him. Ai noted that a fall from that height could've killed them. The Knight reduced Playmaker's LP to 400 and the Data Storm tornado sucked him. Inside the tornado, Yusaku figured out that this was part of Ai's calculations. Ai revealed that powerful monsters reside within the Data Storm, and that Playmaker's skill "Storm Access" allowed him to obtain those Monsters when his LP is below 1000. Playmaker obtained "Decode Talker", which he used to win the Duel. As the Knight fell off his D-Board, Yusaku declared that the Knight had no right to call himself a Duelist.

Playmaker attempted to interrogate the Knight, only for the Knight to attempt to kill him by self-destructing. Ai saved his life by devouring the Knight. Go Onizuka and Blue Angel appeared and challenged Playmaker, but he simply said he wasn't interested and logged out. Yusaku and Shoichi spent the next few days trying to figure out Ai's programming and gave him the nickname "ai". Yusaku discovered some video logs that were actually Ai's memories. Ai said he didn't understand those memories because most were damaged when he was reduced to an eye, but he did recognize The Knight's of Hanoi's leader. Later that night, messing with Ai caused the Knight's leader to sense their location and travel there, Yusaku asked Shoichi to shut down Café Nagi's power to prevent them from being found, though he caught a glimpse of the Knight's leader.

The next day a Knight of Hanoi appeared at LINK VRAINS while Ai was back at Yusaku's house, so Yusaku skipped school to go get his Duel Disk and face the Knight. On his way there, Shoichi gave him the "Decode Talker" card which had materialized. Upon arriving at LINK VRAINS, Yusaku quickly figured out that the Knight was an impostor. The Knight revealed himself to be Go Onizuka, who wanted to defeat Playmaker and recover his title as "VRAINS' hero", Playmaker rejected his challenged but SOL triggered a program that stops Playmaker from logging out until he defeated Go. With no choice, Playmaker started the Duel. When Go made an intentional misplay and took damage, Ai questioned why he would make such an illogical move, to which Playmaker said that humans' hearts make them do illogical things. Ai was confused by that but Playmaker didn't explain what it meant because Ai's algorithm-based thinking wouldn't comprehend it.

Go Link Summoned "Gouki The Great Ogre‎‎" and reduced Playmaker's LP to 100. Playmaker could've reduced the damage he took but chose not to, and refused to use the escape route that Shoichi had built. Ai again was confused by why humans make illogical contradictory choices. Yusaku stated that Go's Duel was meant to entertain the audience and Yusaku himself and that he wouldn't quit the Duel. Playmaker proceeded to win by Link Summoning four times in a row and attacking "Great Ogre" three times with "Decode Talker". After the Duel, Shoichi suggested they should recruit Go for their fight against Hanoi, but Yusaku rejected the idea, saying that he didn't want Go to face the danger of fighting against them.

When Shoichi uncovered Aoi Zaizen's identity as Blue Angel, Yusaku realized that Aoi was a student at Den Academy and his classmate. Shoichi suggested meeting her in order to find out if her brother Akira, who was the Security Manager at SOL Technologies, knew anything about Yusaku's past or Shoichi's brother. However, he then started teasing that talking to Aoi would be impossible for Yusaku because of his lack of social skills. Nevertheless, Yusaku managed to track her down with Ai's help, and followed her to the Duel Club, where Naoki caught up to him. He feigned ignorance when Naoki inferred that he wanted to join the club, and when Hosoda invited him in, he nervously tried to opt out until Ai said thanks on his behalf, which upset him. Yusaku introduced himself to the rest of the club, and the other members introduced themselves as well, including Aoi. When another member, Sato, showed him his Duel Disk, he pretended to be interested, commenting on the fact that it was the latest model. Aoi remarked that he knew a lot, but he said it was only because Naoki had bragged about it earlier. Meanwhile, Ai tried to start a conversation with Aoi's Duel Disk, which made Aoi notice that Yusaku's Duel Disk was a card-loading model, the same as Playmaker's. When she asked to see his Deck, he obliged, but handed her his dummy Deck instead. Ai later complimented him on this, but Yusaku told him to be quiet, as a meeting was in progress.

That evening, he watched Blue Angel issue a public challenge for Playmaker to come out and Duel her. Ai suggested that he should accept, but he refused, since he only approached Aoi attempting to acquire a lead on his stolen memories, and he only Duels against Knights of Hanoi, which she wasn't. Despite this, he was visibly embarrassed when the MC declared that Playmaker wasn't a man if he didn't accept. The next morning, Ai read various posts on social media making fun of Playmaker for not accepting. He soon bumped into Aoi again, and they said good morning to each other. While walking to class, Aoi asked him why he wanted to join the Duel Club, not believing it was because he loved Dueling. When Yusaku tried to ask about her brother, she replied that people only ever approached her to ask if her brother could give them a new Duel Disk or a job at SOL after graduation. She lamented that her brother didn't trust her, and ran off. Soon after, Ai tried to warn Yusaku about a problem he'd noticed with Aoi's Duel Disk, but Yusaku wouldn't hear of it.

In class, Ai suddenly told him to hold up, and Yusaku scolded him for being too loud. He was surprised, however, when Ai said that a Knight of Hanoi had appeared. He went to the balcony behind the Duel Club to enter LINK VRAINS, but instead of a Knight of Hanoi, he found Blue Angel, who remarked that he had finally made his decision about her challenge. He was initially oblivious, but realized that Ai had sent Aoi a text message on Playmaker's behalf challenging her. He became angry, thinking Ai had tricked him, until Ai told him that Blue Angel had Hanoi's card in her Deck, which shocked him. He realized that this was what Ai was trying to tell him earlier, but wondered why Blue Angel would join Hanoi. Ai suggested that Hanoi might be using her to lure Playmaker, and asked what he would do, since he wanted to defeat all Hanoi. Soon after, a Data Storm appeared, and the Duel started.

Playmaker was quickly at the mercy of Blue Angel's Trickstar Deck, which repeatedly dealt him effect damage while powering up the ATK of her ace monster, "Trickstar Holly Angel", and he noted that this offensive strategy was very efficient. He Summoned "Decode Talker" and attacked "Holly Angel" with it, but the attack failed and "Decode Talker" was destroyed instead. Ai commented that Blue Angel was putting pressure on them, but Playmaker noticed that Hanoi's presence was getting stronger. At that moment, Blue Angel drew "Dark Angel", Hanoi's card. During Yusaku's next turn, he was reduced to less than 1000 LP, allowing him to use his Skill and gain access to "Encode Talker", which he promptly Link Summoned. Blue Angel realized that Playmaker was taking advantage of the damage that she was inflicting on him, and tried to end the Duel by using her Skill, but failed because Playmaker was protected by "Defect Compiler". In response, she played "Dark Angel", and immediately fell under Hanoi's influence. She entered into a berserk rage and started screaming, much to Playmaker's and Ai's concern. He ended the Duel as quickly as possible by destroying "Holly Angel" with "Encode Talker", defeating Blue Angel in one hit, but not before she succumbed to mental damage from "Dark Angel" and fell unconscious.

Playmaker then found Blue Angel unconscious while Ai devoured the Hanoi card. He was forced to logout when security bots were incoming and found Aoi in a comatose state on the roof. He proceeded answer Aoi's phone when Akira called and took Aoi to the hospital. He then met Akira who thanked him and questioned his relationship with Aoi, to which he responded that they were just classmates. Yusaku, Shoichi, and Ai then discussed Aoi's condition and a possible cure. Ai said that when he devoured Hanoi's card he detected that Aoi's brain must be infected by a virus, and that the only ones with the appropriate anti-virus would be Hanoi themselves. "Blue Angel" then appeared on the city's screens challenging Playmaker to a rematch. Despite knowing that it was an impostor and most likely a trap, Yusaku claimed it was his responsibility to rescue Aoi; if the impostor was a Knight of Hanoi he could get the anti-virus, on the other hand if it was a SOL agent he could explain them what happened to Aoi. After logging in, he identified Blue Angel as a fake and was trapped by her. She revealed herself to be "Ghost Girl", who accompanied by Akira who proceeded to entrap and torture Playmaker believing him to be responsible for Aoi's condition, despite Playmaker and Ai's claims of innocence and that they were looking for an anti-virus, Revolver appeared and claimed that he would challenge Playmaker for Ai. After threatening Akira that Aoi will never wake up unless Playmaker defeats him in a Duel, Akira released Playmaker and vanished. Before Playmaker took his leave, Akira pleaded with him to save Aoi, despite hating him for his brutal treatment towards him. Playmaker stated that he doesn't hate Akira, he only hates the Knights of Hanoi, much to Akira's surprise.

As Playmaker and Revolver rode off the Data Wind to commence the Speed Duel, Playmaker expressed his desire to battle the Knights of Hanoi and uncover their true identities. Revolver replied that he didn't care about his opinion and stated that his only goal was to retrieve Ai. Both sides agreed on several conditions for their Duel: if Playmaker won, Ai would eat the program from Revolver to get Aoi's body back, while if Playmaker lost, he would give Ai to Revolver. After that, Revolver declared his hatred for AIs and his belief that Ai would lead everyone to destruction. Revolver also blamed Playmaker for assisting Ai and swore to eliminate him. Revolver then waved his hand, causing the LINK VRAINS to be crushed and replaced with lava rivers and fiery lakes, as the Duel finally began.

As the Speed Duel progressed, Playmaker defeated Revolver's "Cracking Dragon" with "Decode Talker" once more, until Revolver revealed that he had the very same skill as Playmaker's and Ai's: "Storm Access". With it, Revolver summoned "Topologic Bomber Dragon", and began to gain the upper hand. Fearing they might lose, Ai led Playmaker to another Data Storm, where the two obtained a dragon. However, Revolver activated the Trap Card, "Remote Rebirth", and combo-ed it with the effect of "Topologic Bomber Dragon", ending the Speed Duel in a DRAW. Following that, Revolver dragged Playmaker and Ai inside a Data Storm, where they began a Master Duel. As the Duel went on, Revolver activated the effect of "Fire Prison", eliminating all Cyberse cards from the field, as well as making Ai seemingly vanish into thin air.

As the Master Duel progressed, Revolver gained the upper hand once more by summoning "Borreload Dragon" and attacked Playmaker directly. Just as Playmaker was on the verge of giving up, he remembered the words someone told him long ago: having three reasons to live and win Duels. Playmaker then called out to Ai, asking him to lend him his power, as he proceeded to Link Summon Firewall Dragon, and ultimately destroyed "Fire Prison," as well as return Ai to consciousness. Ai was amazed to see the two dragons, until Revolver used the effect of "Borreload Dragon" to take control of "Firewall Dragon", but Playmaker countered with "Cynet Refresh" to destroy and revive it back on his field. He then activated "Recoded Alive" to banish "Decode Talker" from his Graveyard to Special Summon "Encode Talker" and declared the real battle was just beginning.

When Playmaker's "Firewall Dragon" used its effect to return "Borreload Dragon" from the field, Revolver informed him that it couldn't be targeted by effects. Playmaker targeted "Magnarokket Dragon", whose effect caused "Firewall Dragon" to be destroyed. Instead, Playmaker's "Cynet Refresh" protected his dragon from destruction. Revolver was amused, and ended his turn. Much to Revolver's surprise, Playmaker had "Firewall Dragon", protected by "Encode Talker", attack "Borreload Dragon", who had more ATK. With "Battle Buffer", "Encode Talker's" ATK was raised, and impressed Revolver for such a strategy. To counter that, Revolver targeted "Encode Talker" with his dragon to reduce the ATK, causing "Encode Talker" to be destroyed and Playmaker's strategy to backfire. While "Firewall Dragon's" ATK was raised by "Battle Buffer", Revolver's "Rokket" dragons regained their effects. Revolver claimed the match was over, as Playmaker could not attack anymore. The latter made him doubt that, since he could not use the effect of "Magnrokket Dragon". Using "Recoded Alive", Playmaker revived "Decode Talker", whose ATK was boosted up to destroy "Borreload Dragon". However, Revolver used "Borrel Refrigeration" to make "Magnarokket Dragon" destroy itself to blast away "Decode Talker". Revolver smiled, seeing how close he was to his victory, with Playmaker having no cards nor attacks to execute. Playmaker refused to lose, and claimed he wanted to uncover the events that had happened 10 years ago, to recover the time he had lost and wanted to save the person that saved him. Revolver was surprised that Playmaker was involved in an incident 10 years ago, He replied he was "that emissary of revenge". Revolver claimed Playmaker was a fool to help SOL Technologies out without knowing the truth.Playmaker refused to listen, and using "Parallel Port Armor", he had "Firewall Dragon" attack once more to perform a One Turn Kill. The attack destroyed "Borreload Dragon", and defeated Revolver.

After Playmaker defeated Revolver, he demanded that Revolver reveal his true identity and those of the Knights of Hanoi. He was shock when he witnessed Ai eating Revolver's arm in order to get his data back. Before Revolver left, he gave the antidote for Blue Angel's coma to Playmaker. Playmaker accompanied Ghost Girl to where Akira and Blue Angel were, using the antidote to cure Blue Angel to allow her to log out of Link VRAINS. Akira thanked him for saving Blue Angel, but Playmaker logged out before Akira could finish. Yusaku became tired and distressed as he logged out. He asked Shoichi if was Aoi alright before collapsing. When Shoichi showed him the footage on how Aoi was doing, Yusaku fell asleep. Ai commented how lazy Yusaku was. Shoichi told Ai that heroes needed rest too. Yusaku dreamed about Revolver's words regarding Ignis with free will, which caused him to wake up. Shoichi sensed he was thinking about what Revolver told about Ai. Since they could not prove that Ai was actually alive, Ai made that assertion. Ai used the program he obtained from Revolver to regain his full body. However, Ai's size didn't impress Yusaku and Shoichi, who tried to determine if Ai regained some of his memories.

As Yusaku was eating hot dogs, he witnessed Emma Bessho visiting Café Nagi to order chili dogs and a coffee. She inquired Shoichi about a Charisma Duelist and mentioned she was interested in Dueling Playmaker, intriguing Yusaku. After Emma left, Yusaku noted how stress Shoichi was and decided to help him delete the files regarding Playmaker. As they were deleting files, Shoichi asked where Ai was. Yusaku told him that he left Ai at home because he was annoying. Despite this, Yusaku wondered about Revolver's words about AI with free will. Knowing Revolver unleashed the attack on Cyberse and searched for Ai, Yusaku claimed Revolver destroyed the Cyberse world. Still, he wondered if it was wise to seek Revolver out for answers about Yusaku's past, and about Shoichi's brother. He then inadvertently deleted a big scoop that would have revealed everything Playmaker and Shoichi knew involving Ai and the Knights of Hanoi, which was about to be published by Frog and Pigeon.

At home, Yusaku thought about Revolver's words about AI with free will in his hidden room. Shoichi called him to come to Cafe Nagi, where Shoichi showed him an encrypted message on an Internet forum, sent to him from Ghost Girl. Shoichi explained that he had created a program to help Ghost Girl enter the Data Storm during the Duel with Revolver. The two read how she requested a Duel from Playmaker, with Ai as the wager. Yusaku accepted, stating that she offered a backdoor to SOL Technologies' data bank, and Shoichi confirmed that fact, showing she did send a bit of the data as proof. Yusaku asked Shoichi to reply that Playmaker would accept her challenge. Ghost Girl soon entered LINK VRAINS, and Yusaku went to do the same. Shoichi wondered if Yusaku would really go and Duel her, since she could've set another trap. Yusaku claimed he had to uncover the truth behind the incident, hoped in the data bank there was some information about Knights of Hanoi, and sensed some determination in Ghost Girl, despite her weaknesses.

Playmaker quickly met up with Ghost Girl and she showed him her program she set as a stake for the Duel. Playmaker wondered why wouldn't she access the data bank, and was told Ghost Girl wanted his Ai, so she could sell it to SOL Technologies. She admitted she grew more interested in Playmaker after his latest Duel, and wanted to battle him as a cyber treasure hunter. Despite Ai's warnings, Playmaker accepted her Duel, as the two rode off on the Data Wind. In her first turn, Ghost Girl Summoned "Altergeist Marionetter" and Set two cards. Playmaker had his "Cyberse Wizard" attack, but was stopped by Ghost Girl's "Altergeist Kunquery". Despite his attack, Ghost Girl was intrigued how he dared to attack, despite her Set cards. Ghost Girl Summoned another "Marionetter", Set another card, then Link Summoned "Altergeist Primebanshee". She swapped one of her "Marionetters" for "Meluseek". Ghost Girl ended her preparations, and aimed to defeat Playmaker before he could use his Skill. As Ghost Girl initiated the Battle Phase and claimed she would win in that turn, Ai laughed, as she would make 2400 LP damage. Both Playmaker and Ghost Girl scolded Ai for such thinking; Playmaker claimed no Duelist would make that simple math error, making Ghost Girl wonder why everyone was after "this dumb AI" which causes Ai to get angry, Playmaker then told him to not to get angry when she is telling the truth about him. Regardless, "Meluseek" attacked directly and sent "Cyberse Wizard" to the Graveyard, allowing "Marionetter" to attack directly, and allowing "Primebanshee" to do so as well. Ghost Girl smiled, feeling her dreams grow larger, and ordered Playmaker to brace himself for his defeat.

Ghost Girl had "Primebanshee" attack Playmaker directly while he Special Summoned "Lockout Gardna". Ai knew they would have enough LP to continue and even use Storm Access, and exclaimed how "bad" this would be. However, Ghost Girl knew Ai was just pretending, and decided not to attack. Ai was in shock, and Playmaker told him his acting was horrible. On Playmaker's turn, Ghost Girl swapped "Meluseek" with "Altergeist Silquitous", by using the effect of "Primebanshee", and also added an "Altergeist Kunquery" to her hand. Playmaker attempted to destroy her ace by Tributing "Backlinker", but was prevented by Ghost Girl's "Altergeist Protocol". Ghost Girl claimed she could anticipate their every move: Playmaker attempted to revive "Backlinker" with "Striping Partner", but was stopped by "Altergeist Silquitos". Using "Lockout Gardna", both effects were negated, though Ghost Girl had one final trap prepared. She noted how Playmaker was an interesting person, as she suspected. Playmaker Link Summoned "Underclock Taker" and tried to weaken "Primebanshee". Ghost Girl countered that with "Altergeist Camouflage", and protected "Primebanshee" from attacks, stating Playmaker had reached his limits.

Playmaker paid 1000 LP to activate the effect of "Balancer Lord", making him eligible to use Storm Access. Ghost Girl refused to let him activate the Skill and used her Skill, Secret Cure to increase both players' LP. Playmaker Special Summoned "Scan Doll", and paid 1000 LP to use "Protocol" on "Silquitos". However, Ghost Girl believed he simply forgot about "Kunquery" she still had in her hand. Playmaker used Storm Access, but Ghost Girl went with him into the Data Storm. However, she lost control of her D-Board and fell off of it, Playmaker saved her and reminded her their Duel was not over yet and let her go back on the D-Board. Playmaker Link Summoned "Excode Talker", whose effect made two of Ghost Girl's Main Monster Zones unusable, and Tributed "Scan Doll" to make his "code Talker" attack twice. Since all of Ghost Girl's monsters could not be targeted for an attack target, "Excode Talker" attacked Ghost Girl twice, and Playmaker won the Duel. Later, Ghost Girl watched the moon, even if Ai reminded her that was just data. Ghost Girl, as promised, gave Playmaker the program to enter the SOL Technologies' data bank, and left. Yusaku logged out of the network, and Shoichi started to analyze it. However, Yusaku was too tired and fell asleep.

Shoichi analyzed Ghost Girl's program, showing Yusaku the schematics, looking like a maze. They both wondered how skilled Ghost Girl was to have managed to hack into SOL Technologies' data bank, and Shoichi promised he would finish by the time school was over for Yusaku to enter the mother computer system. While at school, Yusaku wondered where Aoi was, as he and Ai thought her brother forbade her from entering LINK VRAINS, to protect her from any danger. Ai noticed Yusaku actually cared about her; Yusaku simply stated one should not give up on Dueling this way. As school was over, Yusaku went to Shoichi's van. Shoichi showed the path to the data bank, but warned a lot of traps were set to stop anyone. Yusaku started hesitating, and analyzed that Ghost Girl also wanted something if she gave him the program, even if the information Yusaku could find there may not be that important. Still, he accessed the LINK VRAINS to enter the mother computer system - an eerie, dark place. To protect himself, Playmaker used a device to navigate himself, and a rope to disguise him from security programs. Once the security programs started to go after Playmaker, he launched three "Sphere Kuriboh" to shatter them without alerting anyone. Passing the first corridor, Playmaker arrived to the second one, in which a Data Storm was located. Playmaker was pulled towards it, and his rope broke, alerting the security chief, Kitamura. The latter sent two AI prototypes to hunt after Playmaker, who managed to elude them. However, one of the AI-s caught up with him, and initiated a Duel with Playmaker. The AI prototype brought out "Tentacluster Nautilus", and tributed his "Tentacluster Drillworm", making Playmaker discard all of his cards. Playmaker drew a card, but had to sent it, due to "Drillworm", ending up with no cards to play. The other AI prototype arrived and started attacking Playmaker, intending on grabbing his Duel Disk. Much to everyone's surprise, Blue Angel arrived, using her whip to grab the AI prototype. Playmaker muttered her name, as she declared she would be the one to defeat Playmaker, and started a Duel with the other AI prototype.

Playmaker muttered Blue Angel's name, who came to repay him for curing her. Playmaker claimed he never indebted her; regardless, Blue Angel started the Duel with the other AI prototype. Continuing the Duel, Playmaker banished "Dotscraper" and "Linkslayer" to Special Summon "Dual Assembwurm" from the Graveyard, with its ATK halved, and brought "Dotscraper" with its effect. Using "Cynet Defrag" to summon "Flick Clown" and use the latter's effect, Playmaker had 1000 LP left to use his Skill to grab a Link Monster from the Data Storm. Using his three Cyberse monsters, Playmaker summoned "Vector Square Archfiend", and summoned "Cyberse Wizard" from his hand; the two monsters attacked the prototype's "Tentacluster" monsters, damaging it to 1100 LP. He Tributed "Cyberse Wizard" to use the effect of "Vector Square Archfiend" to revive "Tentacluster Nautilus" and gained another attack. He then destroyed "Tentcluster Nautilus" and defeated the AI prototype, who vanished into thin air. Playmaker entered the Data Bank, and was surprised to see Akira, who expected him to be there. Playmaker questioned Ghost Girl and Akira, as to why they were in the data bank. When Ghost Girl explained that they were after the data, Playmaker figured out that he was just used as a decoy for them to enter the data bank. He ordered Akira to move, who refused, and admitted that he obtained the data, thus knowing what happened to Playmaker ten years ago. Akira claimed he had the right to know about the incident and Playmaker asked of him to hand the data over. Instead, Akira asked Playmaker to hand over Ignis and disperse, wanting to shed some light over the incident, and Ghost Girl added Akira was demoted, due to the incident with Revolver. Yusaku claimed he would be the one to reveal the truth since it didn't personally involve Akira and challenged him to a Duel. He bet Ai for the data, and Akira accepted, seeing this was the only way to defeat Playmaker.

Playmaker Link Summoned "Decode Talker" and used its Link Materials - and "Stack Reviver" - to revive "Cyberse Gadget" and summon a "Gadget Token". Playmaker prepared his offence, but Akira tributed "Tindangle Base Gardna" for "Tindangle Hound" to weaken his monsters and activated "Lemoine Point" to prevent Playmaker from attacking face-down monsters. Playmaker used "Cyberse Gadget" and "Gadget Token" to Link Summon "Flame Administrator". The latter's effect increased "Decode Talker's" ATK, enough to destroy "Tindangle Hound". Akira flipped "Tindangle Angel", reviving "Tindangle Hound" in face-down position, and forced Playmaker to end the Battle Phase. Akira, however, spoke about his and Aoi's past, and didn't wish that Aoi was captured by strangers like Playmaker was. Akira told he would set things straight, and asked for trust. Shoichi and Playmaker became furious, seeing Akira understood nothing about them. Playmaker trusted that Akira was a good person, but doubted he knew anything about the pain he bore. Akira Flip Summoned "Tindangle Hound", and set "Tindangle Angel" into face-down position and gained its attack, plus weakening Playmaker's monsters. Akira attacked Playmaker's "Flame Administrator" and halved his LP. Playmaker used "Limit Code" to bring out "Encode Talker", at the cost of reducing its and "Decode Talker's" ATK. Playmaker saw Akira knew nothing of his goal, as he Link Summoned "Firewall Dragon".

Shoichi Kusanagi
Shoichi is one of the very few people Yusaku actively interacts with. The two are close friends and work together to fight The Knights of Hanoi. Yusaku shows trust in Shoichi's hacking abilities and even gave a brief smile when talking to him. Likewise, Shoichi hopes Yusaku can one day enjoy Dueling again. Shoichi also teases Yusaku about his poor social skills.

Naoki Shima
When they met, Naoki tried to befriend Yusaku and Duel him, but Yusaku showed little interest and irritated Naoki by criticizing his Dueling and analyzing him, despite Yusaku saying Naoki isn't a bad person. Despite their initial encounter, Naoki continues his attempts to befriend Yusaku and he often sits with Yusaku during class, much to the latter's annoyance. Naoki is a big fan of "Playmaker", unaware that he's Yusaku. Yusaku has a tendency to forget Naoki's name repeatedly.

Knights of Hanoi
Yusaku holds a grudge against the Knights of Hanoi over an unknown incident in the past. He swears revenge against Hanoi and fights them whenever they make an attack. The Hanoi consider "Playmaker" to be a threat and plan to defeat him in order to retrieve Ai which "Playmaker" had captured.

Ai
Ai sees Yusaku as a partner, but Yusaku considers Ai to be nothing more than an object he needs to gain the upper hand against the Knights of Hanoi. He threatened to delete Ai in order to challenge a Knight, and ignored his pleas not to go back to VRAINS. Yusaku has little patience for Ai's antics and often doesn't let him talk. Nevertheless, Ai supports Yusaku in his Duels, though he claims to do so out of a desire for survival. Ai also seems to enjoy teasing Yusaku, but knows when things get serious. Likewise, Yusaku follows Ai's advice when needed. Despite being rude to Ai most of the time Yusaku slowly grows to genuinely care about him; this was seen when Ai was deleted by Revolver's "Fire Prison" and he showed legitimate concern for him, showing that despite the rockiness of their relationship, Yusaku does view Ai as a friend and ally. He was also happy when Ai returned to his Duel Disk and playfully teased him for coming back to hostage.

Aoi Zaizen (Blue Angel)
Aoi and Yusaku are classmates, though Aoi is not aware of his alter-ego but she seems be suspicious of his identity as Playmaker after noticing he has the same duel disk as him and asked to see his deck in order to confirm his identity. As "Blue Angel", Aoi is shown to develop an interest in Yusaku's alter-ego, "Playmaker", after he saved her from a "Cracking Dragon". She is shown to be grateful for "Playmaker" for saving her and she even saved him in return after he fell from his D-Board.

After Shoichi figured out that Aoi is "Blue Angel", Yusaku tried to get close to her in order to get a lead on Akira Zaizen and SOL Technology regarding his past memories. Aoi on the other hand believed Yusaku wanted her for her connections to SOL Technologies as many others had tried (which is technically correct, though not for the reasons she assumed), so she quickly dismissed him.

Yusaku was shocked when he discovered that Aoi may have ties to the Knights of Hanoi showing that he never thought of her as an enemy, but he was still willing to duel her. He was visibly disturbed when Hanoi's card began damaging Aoi so he rushed to end the Duel as quickly as possible, out of concern for her well being. After the Duel, Yusaku felt it was his responsibility to help Aoi recover from her coma and willingly walked into a trap set by Ghost Girl.

Yusaku is shown to deeply care for Aoi after he logged out following his duel with Revolver he asked to Shoichi if Aoi is alright and after she recovered from her coma Yusaku is shown to be worried about her safety and well being that she doesn't attend school regularly and since her duel with him she stopped coming to LINK VRAINS. Ai also teases him for being worried about her or being linked with her which causes him to dodge the subject.

Go Onizuka (GO Onizuka)
At first, Yusaku was indifferent to Go who considers his alter-ego, "Playmaker", to be his rival. Go was mad at Playmaker for stealing his spotlight and this grew worse when the children at the city orphanage, which he volunteered and donated to, started seeing Playmaker as a hero instead of him. After defeating him, Yusaku acknowledged Go as a worthy opponent and started to respect his Dueling style, and even admitting to have enjoyed Dueling him. When Shoichi suggested recruiting Go for their fight against Hanoi, Yusaku objected by saying that he did not want Go to face this kind of danger.

Akira Zaizen
Despite having a brief interaction with Yusaku at the hospital he was grateful to him for locating his sister and informing him about her comatose status. He questioned Yusaku about his relationship to Aoi and the latter responded they are only classmates.

On the other hand, Akira dislikes Yusaku's alter ego "Playmaker" for having stolen Ai. Akira grew to utterly hate Playmaker after his Duel against Blue Angel which resulted in Aoi falling comatose. Akira immediately assumed that Playmaker was the culprit for Aoi's predicament and worked with Ghost Girl to turn all of LINK VRAINS into a trap to capture Playmaker. Akira then mercilessly tortured Playmaker and refused to believe Playmaker's explanation that it was Hanoi's fault for Aoi being comatose. However, upon being informed of his mistake by Revolver, Akira reluctantly freed Playmaker and was surprised that Playmaker didn't hate him for what he did. He was to grateful for Playmaker for saving Aoi from the virus.

In their next encounter inside SOL Technology's database, Akira displayed pity for Playmaker after discovering the data he was after, even insisting that Playmaker trust him and reveal the truth in his stead. Compared to their previous encounter, Akira even demonstrates sadness for Playmaker, especially when he figures out that Playmaker is around Aoi's age.

Revolver
When first informed about a hacker named "Playmaker" who was defeating Hanoi members, Revolver initially suspected Playmaker was an agent from SOL Technologies but rejected the idea because SOL would act more publicly and dismissed Playmaker. It wasn't until Playmaker captured Ai that Revolver became interested in him. Revolver then switched all his efforts into defeating Playmaker before SOL did, as doing so was the only way to capture Ai.

Playmaker, on the other hand, hates Revolver for being Hanoi's leader and vowed to defeat him and discover his true identity. During their first Duel, Revolver claimed that he wasn't interested in Playmaker's identity and considered him to be just another of the many people who hates Hanoi.

Cyberse
Yusaku uses a Cyberse Deck. His main strategy involves using methodically calculated moves to overwhelm the opponent with Link Monsters. His early turns are usually slow, with him setting up his bigger combos for later while analyzing the opponent's strategies. Once his field is set up, he Link Summons multiple weak Link Monsters at once to then use them as Materials for his stronger ones such as the "code Talkers", and "Firewall Dragon". His other Link Monsters can also act as support for his primary ones.

After capturing Ai and unlocking the "Storm Access" Skill, he can obtain new Link Monsters when his LP are 1000 or below during a Speed Duel when a Data Storm is near. To this end, he usually allows himself to drop below 1000 LP. The Link Monsters gained this way expand his arsenal of monsters for the current Duel and future Duels alike and typically help turn a disadvantageous situation in his favor. And as shown with "Decode Talker", the data of the Link Monsters added by his Skill will start materializing into a real card. In case the opponent tries to prevent "Storm Access" from activating by not dealing Damage, Yusaku also uses cards with effects that cost LP to get around it.

During his Duel with Go Onizuka, spectators likened this strategy to Go's habit of letting his opponent take the lead, then making a comeback from a pinch.

Yusaku also used three copies of "Sphere Kuriboh" as shields during his inflitration of SOL Technologies' data bank. Whether or not they are in his Deck or not is unknown.

LIGHT
Additionally, Yusaku has a LIGHT dummy Deck for situations in real life where he has to show his Deck to other Duelists. The Deck is poorly built to make it seem like Yusaku is an untalented Duelist.
