In comparison to other series' protagonists, Yusei is entirely different from Jaden Yuki in personality, but has a small number of similarities to Yami Yugi. He has a far more calm and serious attitude than either of them, and is overall depicted as having a no-nonsense personality. Utill Yusei posseses a serious sense when it comes to protecting his friends at all cost. He also values the bonds he has with them, as well as with his cards, like Yugi and Jaden.
Yusei was born in the Tops area of New Domino City. His parents were lead developers for the first Energy system called the Planetary Particle. Dr. Fudo named his son Yusei after the Planetary Particle (Yuusei Ryuushi). As the Zero Reverse was about to take place, Yusei's father placed Yusei an escape pod, getting him out of the vincity before the catastrophe happened
Yusei's parents were both killed in the Zero Reverse and Yusei was sent to an orphanage in Satellite, where he was fostered by Martha.Yusei grew up in Satellite, where he befriended Kalin, Jack Atlas and Crow.
As residents of Satellite, they were made labor for the residents of New Domino City and denied many luxuries, often enjoyed in New Domino.
In the English anime, Yusei is said to have went to an Academy, which Trudge also attended.
Being forced to survive on what he could, Yusei developed hand-to-hand combat and dueling skills. He, along with Kalin, Jack and Crow, became part a group known as Team Satisfaction.Believing they could never leave Satellite, the team tried to make the most of their lives there. They began taking over various regions.
While facing another Duel Gang, one of the members tries to kill Yusei, by throwing him off the roof. Kalin catches Yusei by a Duel Disk cuff, stopping him falling. As Kalin's platform begins to give way, Yusei tells Kalin to leave him and save himself. Kalin refuses to abandon his friend and pulls Yusei up. With that gang defeated, Team Satisfaction have captured all the zones in Satellite.
Sometime later, Kalin forces a kid into a Duel and assaults him after winning. The rest of the gang realize Kalin is becoming cruel and letting the power get to him. Crow and Jack leave the gang, but Yusei stays by Kalin's side.
Sector Security later arrive in Satellite, armed with Duel Runners. Kalin decides to declare war against Sector Security. Yusei leaves the team, hoping that Kalin won't go through with the war, when it's just him.
Kalin proceeds with the war and the rest of the gang return to help Kalin, after he is on the run. The team faced Security, in what Kalin believed to be Team Satisfaction's last Duel. Yusei gets in a fight with Kalin after Kalin attempts to murder a Security. Crow and Jack held Kalin in a room, while Yusei went to tell that he, himself, was the leader, in the hopes that Kalin won't get arrested. Before he could do this, the Securities found and arrested Kalin.
As Kalin is dragged into a Security wagon, the officer pats Yusei on the shoulder, thanking him for assisting in the arrest. Kalin sees this and believes Yusei sold him out, but is taken away before Yusei can explain himself.
Yusei and his friends made several unsuccessful attempts to visit Kalin in prison, until they learnt of his death.
Yusei spends his time with Jack, Blitz, Nervin, Tank and Rally. He develops his computer, motorcycle riding and engineering skills and comes into possession of the card "Stardust Dragon".
Yusei duels and loses to Jack. Angry, Yusei falls down on his hands and knees. Afterwhich Jack tells him that he cannot win a Duel with Monsters, Spell or Trap Cards alone, only with them joined up. Jack points to his heart as he says all you need to amass yourself victory is right here. At the time, Yusei did not understand what he meant.
Yusei was able to pick up TV signals from New Domino, allowing his friends to witness Turbo Duels. He fell out with Jack after a difference in goals, as Jack wanted power and to lead people.With his friends help, Yusei was able to make his own Duel Runner. However, Jack stole the Duel Runner and "Stardust Dragon" in order to escape to New Domino and become the "Turbo Duel King." Yusei had considered these stolen items to be "bonds of friendship" belonging to him and his friends and vowed to get them back.
Two years later, after building a new Duel Runner with the help of Rally, Blitz, Tank, and Nervin, Yusei makes plans to venture to New Domino City to recover "Stardust Dragon" from Jack.
In the process, he runs into Trudge, a Public Order Security officer, who wants to arrest Rally for stealing an acceleration chip. (in the English version, Rally was framed.) Trudge agrees to duel Yusei under the condition that if Yusei won, Trudge would forget the events of that day; if Trudge won, Yusei would give himself up to Trudge. After accepting the challenge and losing, Trudge swears to crush Yusei, but lets him go.
While the only pipline connecting Satellite to New Domino, which is a chute for waste, was closed for maintenance, Yusei took advantage of this to escape to New Domino. On the way, he gets chased by Trudge, who forces him into a Turbo Duel. Yusei manages to defeat Trudge and get out of the pipeline, just before it reopens. Trudge is pushed back down the pipeline as the waste flows in.
Yusei manages to find Jack, who tosses "Stardust Dragon" back to him, telling Yusei he can have it. Yusei refuses, saying that he would rather duel him for it to prove he can get it on his own. Jack agrees, but their Turbo Duel is interrupted by the appearance of a Crimson Dragon right before the winner is determined. The Dragon causes Jack's already permanent Birthmark to glow and burn as well as revealing Yusei's Mark, the Dragon's Tail. Yusei is arrested shortly after for trespassing into New Domino while Jack leaves safely. Rex Goodwin and Lazar, who had been monitoring the Duel, reveal that if the Crimson Dragon hadn't appeared, Jack would have lost.
After his arrest, Yusei got a marker, signifying his criminal record, and was sent to the Facility, where he met Tenzen Yanagi. Yanagi informs Yusei of the Crimson Dragon and the Signers, telling him that those who have the birthmarks were chosen by the People of the Stars. Yusei's birthmark is the Crimson Dragon's Tail, which appears on his arm when he fights alongside Stardust Dragon or encounters another Signer.Yusei meets former pro Duelist, Bolt Tanner, who imposes a Duel. Since Yusei's cards had been confiscated, Yanagi duels Tanner. Disgusted at Yanagi's poor dueling and his cards, Tanner stamps on the cards, despite their sentimental value to Yanagi. Yusei tosses Tanner back and challeneges him to a Duel, borrowing Yanagi's Deck. Yusei wins and Tanner offers his assistance to him. Under Goodwin's orders, the warden Armstrong is made carry out tests on Yusei. Armstrong also has Yusei send to a different part of the Facility.
Yusei's new cellmate Alex offers Yusei a chance to escape through a tunnel he's been working on for months. Yusei agrees to come if they can take Tanner and Yanagi too. However Armstrong has Tanner and Yanagi beaten for knowing Yusei. Yusei stands up to Tanner, causing Tanner to impose stricter rules and challenge Yusei to a Duel.
Yusei refuses to escape with Alex, as Tanner and Yanagi are unable to come too and escaping wouldn't grant true freedom. Without a Deck to use against Armstrong, the other inmates give Yusei cards to use against Armstrong. The next day Yusei faces Armstrong, using the Deck of random cards. The Duel is setup to shock players if they suffer damage, but Armstrong rigs the arena to stop himself receiving shocks and uses surveillance cameras to see Yusei's cards. Alex, however uses his tunnel to sneak into a security room and switchs Armstrong's shocks back on.Despite Alex's effort, Yusei is ultimately defeated by Armstrong. Yusei relinquishes his pride and dignity, and gets down on fours, begging for mercy and forgiveness. Armstrong mocks and ridicules Yusei. Godwin, who witnessed the entire scene, allows Yusei to leave after seeing Yusei performing such a humiliating act. Godwin also punishes Armstrong for mistreating the inmates. Yanagi gives Yusei his "Totem Pole" card. Tanner gives him his "Giant Ushi Oni", instructing him to to meet Blister at Bootleg and use the card to prove he met Tanner.
Yusei is followed by two stalkers at Bootleg, but is pulled away by Blsiter on his Duel Runner. Blister jams the signal emitted from Yusei's criminal mark to stop them being followed.
Despite believing it to be suicide on Yusei's part, Blister helps him in infiltrating a Security warehouse to recover his Deck and Duel Runner.
Disguised as an electrician, under the pseudonym Yusei Adams (Taro Daimon in the Japanese version), Yusei was able to sneak into the warehouse. When he gets to the crate, where his Duel Runner is held, he is ambushed by Trudge. Yusei hops onto his Duel Runner and smahes it through the crate. Trudge forces him into another Turbo Duel. After Trudge starts physically attacking Yusei, Blister arrives to help, having had a change of heart over what Yusei told him about friends. Yusei wins the Duel, but is electrocuted and left unconscious outside the warehouse.
Yusei is later given refuge by the twins Leo and Luna. In the Japanese version, he fears that he would only cause them trouble by staying, but they manage to talk him into a Duel and staying for the night. In the English version, Yusei has lost his memory after his Duel with Trudge and can't even remember his name. He duels Leo in the hopes of regaining his memory, whilst in the Japanese version, Yusei is reminded of Rally through Leo's personalities.
After leaving the twins, he is threatened into participating in the Fortune Cup by Lazar, who holds his Satellite friends hostage. Yusei is later given more incentive to participate when Jack gives "Stardust Dragon" back and personally demands that he face him. In the quarter-finals of the Fortune Cup, Yusei faced Hunter Pace, disguised as Shira, and won, moving to the semifinals. His opponent in the semifinals is Greiger.After Yusei defeats Greiger, Greiger attempts to take revenge on Goodwin for what he did to his village, but Yusei manages to stop him. Before security takes Bommer away, he tells Yusei to fulfill his own mission. In the English version, Yusei stops Greiger from knocking down the tower Goodwin was in to get revenge on what Goodwin did to his village, but a spike broke through the glass at the top of the tower (where Goodwin is) from the collision with Greiger's Duel Runner and Yusei's Duel Runner and Goodwin stopped it with his hand. As security takes Boomer away, he tells Yusei to be careful in the finals in the English Version.
Yusei faces Akiza in the finals. Previously, he had thought that she only felt anger and rejection. But after Akiza's first move, he notices and points out that she has a pleasure and joy for destruction. Akiza replies that cannot be true, however, later on the duel, after people insult her again, she accepts it all because of being the "Black Rose". According to her, this other side of her is the one who enjoys destruction all because of the powers caused by the Mark of the Dragon. He learns that after she was found by Sayer, he told her to feel but not to think, to let him do that for her. But even still, she puts on her mask just to feel; this prompts Yusei to fight this duel to change her.By the end of the Duel begins as he says that her pain which came from all the destruction she caused was turned into one that the other Signers shared. Yusei tells her that the birthmark may hold the answer for her pain, but in order to find out, she must think and love herself. Akiza still intends to deny this by winning the duel without noticing, as pointed out by Yusei, who has seen through her, that she is crying. Thus he eventually wins, resulting in her mask cut in half due to "Cosmic Blast" and after she falls, Akiza tells him to "help her".
He faces Jack near the end of the Fortune Cup. Although he is pushed to a corner in the middle of the Duel, Yusei wins using various combos with "Stardust Dragon" to destroy Jack's "Red Dragon Archfiend" and becomes the new King of Turbo Duels.
Following his victory against Jack, Yusei flees the stadium with Tanner, Yanagi, Luna, and Leo to avoid being mobbed by reporters and fans. They hide out at Blister's place at the edge of the city.
Yusei spots a man with a glowing birthmark. Believing him to be a Signer, Yusei chases him to a construction site where he faces him in a Shadow Duel. The opponent, Dick Pitt reveals himself to be a Dark Signer and states their motives to destroy the Signers. After Dick loses, he has no memory of the Duel, his Deck changes and his dark mark disappears. Yusei runs away after Security appears to examine the damage caused by the Shadow Duel. After returning to the hideout, Security led by Trudge track him down. Yusei walks out to meet them and says he wanted to talk to Goodwin anyway (in the English version, Yusei called Trudge to take him to Goodwin).
Yusei is taken to meet Goodwin at an incomplete bridge pointing in the direction of Satellite. Here Goodwin tells him about the battle between the Crimson Dragon and the Earthbound Immortals, where the Five Dragons sealed the Earthbound Immortals in the Nazca Lines. Goodwin says that those bearing the mark of the Crimson Dragon and the Earthbound Immortals' servants, the Signers and Dark Signers have been battling for 5,000 years. Their battle is destined to determine the fate of the world. The old Enerdy system in Satellite is a door to the Underworld itself, which the Dark Signers plan opening, to release the evil sealed in the Nazca Lines. Yusei understands Goodwin deliberately isolated Satellite from New Domino to restrict the battlefield to Satellite, only harming the Satellite residents. Yusei requests that they evacuate Satellite, but Goodwin says can't, since it would allow the Dark Signers to target the city, insuring a greater amount of casualties. Goodwin arranged a helicopter to airdrop Yusei and his Duel Runner into Satellite.After arriving in Satellite, Yusei is reunited with Crow. The two head back to Yusei's Satellite hideout, where he is reunited with Rally and the others. Security had been following Crow, so Yusei and Crow team up to get rid of them, beating them in a Tag Turbo Duel. After the Duel Yusei and Crow meet up with Rally and his others at Crow's base at Daedalus Bridge. here Yusei tells his friends about the disastrous vision shown by the Crimson Dragon and the story told by Goodwin. He listens along with the others the story about the man who made the bridge. During the night both he and Crow had head to the B.A.D., where the old Enerdy system is. They are confronted by Kalin, who is now a Dark Signer. Kalin shows great hatred to his old friends and forces Yusei into a Shadow Turbo Duel. Kalin takes the upperhand with "One-Hundred Eye Dragon". Yusei is able to comeback with "Stardust Dragon", but Kalin turns the tables and Summons his Earthbound Immortal, "Ccapac Apu". Before Yusei is defeated his Duel Runner breaks down and the Duel is canceled. Yusei is then found impaled in the abdomen by a large shard.
Crow takes him to Martha's refuge facility, in order to receive the required surgery. Dr. Schmitt, assisted by Martha manage to save Yusei's life. After waking up he sees that Rally and the others brought his Duel Runner all the way from the B.A.D. Yusei gets scolded by Martha for putting himself in danger, without asking his friends for help. She reminds Yusei of his idea of "believing in friends" as they will always be there supporting and helping him out. As he recovers, he checks his Duel Runner and thinks that Kalin is too powerful for him to defeat.
As Akiza is about to duel Misty, Yusei's birthmark reacts. He rushes outside and sees Hummingbird and Lizard Earthbound Immortal marks. He is aware a Duel between a Signer and Dark Signer is about to begin, but is unable to assist. After Akiza is is taken to the hospital, her parents turn to Yusei for help. Yusei is initially reluctant, but prompted by Martha, who teases him for having a crush on Akiza.When Akiza awakens, she is initially glad to see Yusei, but after seeing her parents, turns against him. Unable to calm her, Yusei tries to reach her by dueling. Yusei takes damage through the Duel, but Hideo steps in to protect him. With Hideo's determination, Yusei is able to show Akiza that her parents love her.
Mina shows Akiza and Yusei information regarding the Arcadia Movement and Sayer 's true motives, involving the abduction of children to create an army of Psychic Duelists. Yusei comforts Akiza from the devastation.The Signers are invited to Rex Goodwin's house. Despite his distrust of Goodwin, Yusei decides to go, as this is the only way he get information on the Signers and Dark Signers. Yusei asks about reverting a Dark Signer back to normal. Goodwin reluctantly tells them that Dark Signers cannot be brought back as they are dead and no longer of this world. Yusei loses confidence in returning Kalin back to normal and blames himself for Kalin's current state. Jack, who is sickened by Yusei's whining and self-doubt, punches him in the hopes of returning some sense to Yusei. Jack's actions and words, along with some moral support from the twins, restores Yusei's confidence.
When the four Signers return to Satellite along with Mina, Leo and Trudge meet up with Martha. They learn that Rally, Blitz, Tank, Nervin and Crow have disappeared. While everyone is sitting down to supper, Rudger interrupts. Jack wants to duel him, but Yusei tells him that its too dangerous to duel here with the flaming geoglyph. Yusei instructs Jack to take Martha and the kids to a safer place.
Yusei duels Rudger, while accompanied by Akiza. During the Duel, he witness two of the children, who stayed behind and Martha get sacrificed to Summon Rudger's Earthbound Immortal. After Yusei Summons "Stardust Dragon", Rudger leaves and revives Rally as a temporary Dark Signer to face Yusei. Rally sacrifices himself to help Yusei. To avenge Rally's sacrifice, Yusei swears the Dark Signers be defeated with everything he has.
The four Signers separate and head to each of the 4 Old Enerdy controllers where their respective opponent is waiting. Yusei head's towards Kalin's tower, but spots a column of light coming from where Luna went. Yusei finds Leo dueling Demak. Yusei tries to stop the Duel, but cannot due to the natures of the Shadow Duel. Yusei is left with Trudge to watch helplessly.
He witnesses Luna comes back and assist Leo, shortly after Demak Summoned Earthbound Immortal Cusillu. Together the twins, defeat Cusillu and Demak. Afterwards Ancient Fairy Dragon and Regulus appear to thank Luna, who tells them she couldn't have done it without Leo or Yusei. Yusei and the twins proceed to the control tower to activate the safety switch.
When the Killer Whale geoglyph appears, Yusei finds Crow dueling against Greiger, who is now a Dark Signer. Yusei tries to talk them out of the Duel, but both feel that they are fighting for the people they love and refuse to stop.After Crow's duel, Yusei proceeds to Kalin's tower, intending to save him. Both engage in a Shadow Turbo Duel. Towards the end of the Duel, all of the birthmarks disappeared from the Signers' arms and then unite to form an image of the Crimson Dragon on Yusei's back. Because of this, Yusei is able to Summon "Savior Star Dragon" and destroy Kalin's Earthbound Immortal. Yusei manages to reconcile with Kalin before the Dark Signer turns into dust.
Yusei heads to Rudger to request a final Duel. During the Duel, he learns of what happened in the Old Enerdy incident and more about his father. Yusei manages to defeat Rudger, but in the latter's moment of defeat, Rudger triggers an explosive that destroys the bridge they were dueling on, leaving Yusei to fall into the pool of Old Enerdy.
Yusei ends up in a strange place, where people who died during the Zero Reverse accident reside. The souls start to attack him, but are stopped by Yusei's father. Professor Fudo helps Yusei to escape the Underworld.
Yusei and his companions go up through the same stairs they used before. In the distance, they see purple sparks and deduce that Jack has won his Duel and activated the third safety switch.
Yusei goes to the last tower, where Akiza is dueling. He encounters Sayer in disguise, who lures him into a room. Inside, Mina is locked in a cage below. Sayer reveals himself and tells Yusei that Akiza is not a friend but a mind slave of his. He quickly subdues Yusei and throws him into the cage with Mina. Before leaving, Sayer seals the cage by using a Hinotama and fills the cage with water before leaving them to die.
After being rescued by Trudge, Yusei confronts Sayer, who by then has gained control of Akiza. They get into a fight and Sayer reveals that he was the one who killed Misty's brother, Toby. Just when Yusei was about to be blown off the building, he tricks Sayer into revealing this to Misty through his Duel Disk's microphone.
After Sayer is eaten by Misty's Earthbound Immortal, Yusei snaps Akiza out of her daze and she manages to defeat Misty. However, the sun sets before they can activate the safety switch, and so the Condor geoglyph appears in the sky.
Yusei, Jack and Crow face the last Dark Signer, Rex Goodwin in a 3-on-1 Shadow Turbo Duel.
A year after the duel with Rex Goodwin, there will be a Turbo Duel Tournument and which Yusei devotes to making a new machine for.Yusei hopes to make a new engine to improve thier [Yusei Jack,and Crow's] duel runnners for the W.R.G.P [World Raceing Grand Prix] they enter as a team [Which can only be in teams of three] shortly after a mysterious new duelist who calls himself the ghost apears.
