Hoping to save his friends from the clutches of Sector Security, Yusei Fudo challenges his old nemesis Officer Trudge to a Turbo Duel!
Yusei reflects on his past battle with Jack, vowing to win back his Stardust Dragon card which Jack took from him. Later, Tank, Nervin, and Blitz are challenged by a group of thugs, led by a person named Uryu. Yusei steps in to help his friends out, and ends up in a duel against Uryu with his Duel Runner at stake.
Yusei begins his ride to New Domino City to face Jack. On the way, Trudge forces him into another Turbo Duel. With only three minutes left to make it out of the pipeline, and Trudge's Gate Blocker preventing him from gaining Speed Counters, Yusei seems to be getting desperate - until he pulls out a special monster given to him by Rally.
Yusei, intending to win back his Stardust Dragon, meets up with Jack and challenges him to a Turbo Duel. The battle begins in the now deserted Duel Stadium. Yusei finds himself up against not only the fearsome Red Dragon Archfiend, but also his own Stardust Dragon which Jack placed in his deck.
Yusei and Jack's battle continues, with Yusei finally regaining control of Stardust Dragon. Both Yusei and Jack's arms burn as Stardust and Red Dragon Archfiend clash, and both their dragon-shaped birthmarks begin glowing. A third Dragon appears in the sky, blazing red. The duel ends with no victor and the appearance of New Domino City Security forces.
Yusei is arrested and sent to a detention center, where he meets an old man named Yanagi, who duels using what he calls his "Hidden Treasure" deck. Yanagi faces off against another prisoner, Bolt Tanner - and is shortly revealed to be a very poor duelist. Although lacking skills, he still cares deeply about his cards, something Yusei can relate to. Meanwhile, Goodwin reviews Jack's duel with Yusei, and discovers that, had they not been interrupted by the appearance of the Crimson Dragon, Jack would have been defeated.
Yusei has had enough of hearing Tanner making fun of Yanagi's cards and dueling skills, so he takes up Yanagi's deck and challenges Tanner to a duel, much to everyone's surprise, since Yusei is not dueling with his usual cards. Yusei wants to teach Tanner that every deck has a winning strategy, regardless of their value to others. Goodwin reveals to Jack the legend of the People of the Stars, the Signers and the Crimson Dragon.
Yusei is interrogated for information on his Dragon Mark, and Goodwin comes to the detention center to speak with him further. Yanagi tells Yusei what he knows about the Signers and the five dragons, and suspects that Yusei's Stardust Dragon may be one of the five. Meanwhile Jack duels Hunter again, but is off his game after his loss against Yusei.
Yusei is transferred to a different cell, away from Yanagi. His new cellmate, Alex, plans to escape and offers to take Yusei with him, but he refuses to leave without Yanagi and Tanner. Meanwhile, Armstrong has been harassing Tanner, and Yusei ends up in a duel against him, using a deck built with treasured cards given to him by all the other prisoners.
Yusei is caught in Armstrong's trap - not only is he forced to discard ten cards each turn, each Life Point lost also delivers a painful electric shock. Armstrong has disabled the electric current to his own Duel Disk, and thus does not feel any pain, until Alex breaks into the control room. He starts the current flowing again, but Armstrong just gets back up and keeps going. Despite the overwhelming odds, Yusei is able to pull through and win the duel. He is allowed to leave the prison.
Although he is now out of the detention center, Yusei has noticed that he is being followed by Goodwin's agents. Luckily, he is taken by a former duelist named Blister, the man who Tanner told him could help get his Duel Runner and dueling deck back. After discovering Blister's past, Yusei infiltrates Goodwin's tower and finally recovers his Duel Runner and dueling deck, but not before Trudge shows up and challenges him to another Turbo Duel.
Yusei continues to avoid Trudge's brutal direct attacks as he attempts to escape with Bliser's help, but things only get harder from there. Despite the danger, Yusei resolves to restore Blister's faith in bonds with other people. When Trudge brings out Goyo Guardian, Yusei tunes four of his weak monsters together to summon Turbo Warrior.
Yusei is able to escape from the police, but crashes his Duel Runner and is knocked unconscious. When he wakes up, he has been rescued and hidden from the police by twin duelists Leo and Luna, who live in the Tops area at New Domino City. Rejoiced to see that Yusei is alright, Leo asks him for a friendly duel-Yusei's Junk deck against Leo's Morphtronic deck. In the English version, Yusei suffers from amnesia following his crash, and Leo duels him in order to make him remember.
While preparing for the Fortune Cup with Blister, Yusei is reunited with Tanner and Yanagi. As they prepare to test out Yusei's Deck, they're confronted by Jack, who returns Stardust Dragon to Yusei. Later, Leo tells them about a duelist called the Black Rose Witch. (Known simply as the Black Rose in the English version). When she appears before them, the Mark of the Dragon on Yusei's arm begins to react.
The Fortune Cup has officially begun and the first duel pits Krieger against Leo, who is disguised as his sister Luna, as she did not wish to participate. Krieger's aircraft machine monsters are giving Leo's Morphtronic monsters a hard time. Meanwhile, Zigzix, Goodwin's scientist, puts his latest invention to the test: a device that detects signer activities. But Leo is unaffected while Luna is. Leo loses his duel and Zigzix finds out that Luna was in the stands during the duel.
The next duel in the Fortune Cup pits Gill de Randsborg vs. Akiza. Randsborg has learned from Goodwin and Lazar that Akiza is the Black Rose. At first, his Masked Knight leveled monsters seem to give him a clear advantage, until Akiza lets everyone in the stadium witness the dangers of her plant monsters, field spell card and finally, her Black Rose Dragon.
Next up in the Fortune Cup is a riding duel between Yusei and a mysterious caped duelist called Shira, but to Yusei's and Jack's surprise, the challenger is actually Hunter Pace who took the real Shira's place and disguise shortly before the duel starts. Yusei must now face Pace's deck filled with powerful Fire monsters, an improved deck which Pace planned to use against Jack later on.
The first round of the Fortune Cup is over, but Rex Goodwin is holding a consolation match, which opposes Professor Frank (Known simply as The Professor in the English version) versus the real Luna, much to Leo's disappointment. Not only Luna is reluctant to duel, but the duel itself is planned to uncover Luna's signer ability. Furthermore, Professor Frank has a stirring speech that sends Luna into a trance-like state, disrupting her dueling capabilities.
Luna engages in her duel with Professor Frank when she hears a mysterious voice saying: " You said...you'd protect the world of Duel Monsters spirits. " Then, the voice takes shape in the form of Ancient Fairy Dragon. Now, Luna must take all her courage and skill at hand to defeat Professor Frank's trump card.
The first day of the Fortune Cup comes to a close. The audience attention is cast to an image of Krieger, who shall face Yusei tomorrow. As Tanner says that he wonders what kind of Duel Runner Krieger uses, something comes to Leo's mind, causing him to run off.
Krieger successfully summons Flying Fortress SKY FIRE and uses its effect to prevent Yusei to play his cards right. What Yusei doesn't know is that Krieger holds Goodwin responsible for the destruction of his home village.
The second round of the finals pits Akiza against Commander Koda. Koda has been ordered by Goodwin to expose Akiza as a signer, which didn't work on Akiza's last duel. Furthermore, Koda can expose his opponents' past to disable them. He doesn't take long to expose Akiza's troublesome reputation as the Black Rose, awakening painful memories to Akiza.
Before the final rounds of the Fortune Cup commences, Yusei confronts and questions Akiza within a inner passage of the Dueling Stadium of why does she calls the Mark of the Dragon a "Wretched Mark." To which angrily responds that she hates and detests the person who carries a birthmark. Furthermore while becoming angry, Akiza feels that something remains hidden within her. Yusei, who is filled with various doubts, begins his Duel with Akiza.
The duel between Yusei and Akiza continues, and Akiza quickly gains the upper hand. Yusei, from his part, manages to put a good defense against Akiza's plant-type monsters, but also notices that Akiza takes a guiltiest pleasure at attacking him mercilessly.
Yusei wins his match against Akiza, but feels reluncant about it since he couldn't help her as much as he would have wished. He then rushes to Goodwin's tower in order to rescue his friends, but what he finds is Jack along Goodwin, and he explains how his rivalry with Yusei all began. Shortly after, the final duel between Jack and Yusei takes place, and to Yusei's surprise, his friends from Satellite are safe and sound, freed from the container that served as prison in Satellite, and they all watch Yusei as he duels.
The Fortune Cup Finals continue as Yusei summons Stardust Dragon to battle Jack’s Red Dragon Archfiend. As the battle goes on, the Crimson Dragon appears and Goodwin, revealing that he is the fifth signer and has a severed arm in a tank with the final Signer Mark shows Yusei, Jack, Akiza, and Luna bizarre visions of the People of the Stars and the future of New Domino City, being engulfed in a Spider shaped geoglyph of fire.
After his victory over Jack in the Fortune Cup, Yusei is named the new Duel King. While Yanagi informs the gang about the Signers and the Dragon Birthmarks, Yusei is challenged by a mysterious man with a Spider shaped birthmark on his arm who is able to make the duel into a Shadow Duel. Yusei is surprised to find his opponent has a fearsome new type of monster, a Dark Synchro Monster. Meanwhile, a reporter named Carly tries to get the scoop on the new Duel King.
Despite the difficulties caused by the Dark Synchro Monster, Yusei manages to win his duel against the Dark Signer. However, after the duel, his opponent has no recollection of what happened and no longer has the birthmark or any Dark Synchro Monsters in his deck. It is revealed that spiders are being used to control people, one of which are heading to the hospital where Jack is recovering. Trudge arrives to take Yusei back to the Satellite, and Yusei decides to go, with intention of getting the truth out of Goodwin.
Following her release from security, Carly attends a premiere event and encounters a model named Misty, who predicts her death. When Angela, a rival reporter, reveals Jack was actually born in the Satellite, Carly decides to infiltrate the hospital to interview Jack. At that time, a Dark Signer spider possesses Trudge and challenges Jack, who is trying to leave the hospital, to a duel. Unable to use his fractured right arm, Jack decides to use Carly as his arm. They win the duel, but Jack is weakened and asks Carly to get him out of there without anyone noticing. Meanwhile, Goodwin shows Yusei the truth.
A Satellite rebel named Crow steals several decks for his friends. He is forced into a duel by Security, but manages to beat them with a one-turn kill. As Goodwin tells Yusei the truth about Signers and Dark Signers, Luna has nightmares involving the dragons. Mina and Trudge show up at Carly’s place where they find Jack, but he refuses to go with them. Yusei is then sent back to the Satellite where Crow awaits him.
After catching up with each other and reuniting with Rally and co, Yusei and Crow are forced into a Turbo Duel with security using Tag Duel rules. Meanwhile, Carly accompanies Jack around the city whilst Mina and Trudge follow. Jack reminisces about his life in the Satellite, and the friends he betrayed. Following some advice from Carly, he decides to follow his own path.
Rally and friends meet up with Yusei and Crow at his hideout, where Crow tells a story about the man who made the Daedalus Bridge. Later that night, whilst Yusei and Crow search for the Dark Signer’s whereabouts, Kalin, a former friend of theirs, sends out a Dark birthmark signal, alerting Yusei and the other Signers. Jack and Carly are escorted by Mina to Yusei’s whereabouts, where Carly learns that Yusei was born in Tops, and his parents were involved in the Zero Reverse incident. Kalin makes his appearance, trapping Yusei in a geoglyph shaped like the Giant Nazca Line and forcing him into a Dark Turbo Duel.
While preparing for his duel against Kalin, Yusei, Crow and Jack remember when they were all part of a duel gang, the Enforcers, who duelled rival gangs at night. The duel starts and Yusei takes a harsh attack due to the effects of the Shadow duel, which appears to be more dangerous in Turbo Duel.
Kalin summons his One-Hundred Eye Dragon, a Level -8 Dark Synchro monster, causing a real threat to Yusei. Yusei once again recalls his days in the Enforcers, and remembers how Kalin once saved his life. When he is almost burned in the fires of the dark barrier, Yusei also remembers when Kalin killed a member of Security and how the proceeding fight between them sparked Kalin’s hatred towards Yusei.
Yusei defeats One-Hundred Eye Dragon using Stardust Dragon, but Kalin summons a powerful monster, an Earthbound Immortal, called ‘Ccapac Apu’ using the souls of all the captured Satellite inhabitants, unphased by attacks from Monsters, Spells or Traps. Before it can attack, Yusei’s Duel Runner gives out and crashes, ending the duel. However, Yusei is impaled by a shard in his abdomen and is taken to a local doctor in Satellite by Crow. Meanwhile, Yusei’s friends try to retrieve his broken Duel Runner while staving off Satellite thieves. However, in the english adaptation, Yusei suffers internal bruising to his abdomen after his duel with Kalin.
As Yusei recovers from his operation, Leo assumes he is the Fifth Signer since his monster, Power Tool Dragon, apparently appeared in Luna’s dream. He comes up with the idea of recruiting Akiza to fight the Dark Signers and goes with Luna, Tanner and Yanagi to visit Sayer in order to see her. However Sayer gasses them, and has his own plans of recruiting Luna into the Arcadia Movement, locking up Tanner and Yanagi and forcing Leo into a duel with his sister on the line, for if he loses Luna will stay and become a member of the Arcadia Movement, while Luna watches with Akiza. Leo temporarily gains the upper hand by summoning Power Tool Dragon, but is then defeated by Sayer’s Synchro Monster and is left unconscious.
Jack decides to return with Mina to the city to retrieve his Duel Runner. He thinks it is too dangerous for Carly to get involved but promises to tell her everything when it’s all over. Carly, wanting to maintain her contact with Jack, decides to look into Akiza and the Arcadia Movement, and finds out Misty is somehow linked to them and goes to meet her. She reveals that Akiza was apparently responsible for the death of her younger brother.
New Domino City is shaken by an earthquake as a new geoglyph is set ablaze. To Sayer’s surprise, somebody shows in his office: Carly, alive… and as a Dark Signer. She challenges Sayer to a Shadow Duel for revenge, and Sayer is shocked by her new monsters’ abilities. Noticing the geoglyphs, Jack heads towards the action, almost being engulfed by the flames in the process. Meanwhile, Akiza is approached by Misty, who challenges her to a duel, as a dark signer as well.
During their duel, Misty informs Akiza that she is responsible for the death of her brother, which Akiza denies. Tanner and Yanagi rescue Luna and Leo from their imprisonment, and discover the two duelists along the way. A barrier coming from Luna’s birthmark protects the others as countless souls are sacrificed when Misty summons her Earthbound Immortal, Ccarayhua.
Akiza is taken to hospital where her parents, Hideo and Setsuka, meet up with Jack, Leo and Luna. Jack tells them that the only one who can save Akiza is Yusei, so Hideo travels to Satellite to talk with him. He tells him that when Akiza was young, he was unable to spend time with her due to work. When they finally were able to spend some free time together, a call from work interrupted, which frustrated Akiza and awoke her Signer powers and birthmark, hurting her father in the process.
Enduring the pain of Akiza’s attacks, Yusei summons Stardust Dragon to face against Black Rose Dragon and reach her heart. Still hurt by the loss of Sayer, Akiza unleashes her full power and constantly weakens Stardust Dragon. As Yusei gets hit by more attacks, Hideo steps in to protect him and try and reach Akiza, taking some damage in the process.
Before visiting Goodwin, Mina shows Akiza the true nature of the Arcadia Movement, showing how they performed experiments on young children in order to raise Psychic Duelists. Yusei, Jack, Akiza, Luna and Leo go to Goodwin in order to get the truth. Goodwin almost denies Leo entry, since he is not a Signer, but Luna insists that he stay with them.
The Signers contemplate about what Goodwin had told them. Yusei blames himself for Kalin becoming a Dark Signer, but Jack punches him in the stomach and face to knock some sense into him Yusei then punches back. Leo is reluctant to join Luna in going to the Satellite, since his battle with Sayer proved he wasn’t a worthy hero.
Crow manages to regain some ground in his duel against Lazar with his monster, Black Feather Arms Wing, but just then, a purple light shines from the Original Enerdy Reactor within a crater Lazar was investigating, and a black fog starts to envelope Satellite. Whilst Lazar manages to escape, Crow gets caught up in the fog and disappears, along with several Satellite citizens.
While flying to the Satellite Akiza asks about Yusei’s father and Mina explains to everyone what his father did. She also explains what happened 17 years ago and that Yusei is city born. Yusei, Jack, Akiza, Leo, Luna, Mina and Trudge arrive Martha’s house where she and Blister are waiting. Martha informs everyone that Crow, Rally and the others have gone missing, and offers everyone a meal. Then Yusei answer Martha’s question if the girl that’s sitting there at the table is Akiza and then Martha states he saved her.
As Roman prepares for his Earthbound Immortal summoning, Yusei tries his best to postpone it and Martha and Trudge hurry to save the children. However, Roman then speeds up the process and is able to summon his Earthbound Immortal, Uru. Thankfully, Jack arrives on time and forms a barrier around the children to stop their souls being sacrificed. Roman then reveals that not only was he an assistant to Yusei’s father, but is also Goodwin’s brother and the one responsible for the Zero Reverse incident. Yusei manages to deflect an attack from Uru’s attack, but it hits a building Taka, Martha and Trudge were hiding in.
The Dark Signers show up to taunt the Signers following Yusei’s duel with Roman. Devack introduces himself and reveals he is in possession of Ancient Fairy Dragon and challenges Luna to come get it. Roman announces that their duels will take place at the four stars of destiny. Whilst chasing after them, Jack discovers that one of the Dark Signers is Carly, who tells him to find her if he wants to know what happened.
As Luna reaches a town in the Spirit Realm, she notices that its inhabitants are running frightened, and gravity is behaving oddly. She is discovered by a group of monkey soldiers, who imprison her card spirits in stone tablets with minus levels. She is rescued by a young mage named Torunka, who decides to help Luna find Regulus, the servant Ancient Fairy Dragon spoke of.
As Luna and Torunka manage to find Regulus, Luna notices he has a Minus Staff stuck in his leg, causing him to hear the opposite of what Luna says and become distrustful of her. Luna manages to steal one of the foot soldier’s Minus Staffs to negate the one on Regulus, and when he notices she is a Signer, he decides to help them.
Luna’s plan to free Ancient Fairy Dragon is hampered when the Minus Staff she was carrying gets revealed, causing Torunka to accidentally blurt out their plans. Regulus manages to destroy Zeman, who is simultaneously destroyed by Leo in the real world, but not before Zeman transfers the power of the minus curse to Devack. This returns Torunka to his normal age, but doesn’t free Ancient Fairy or the minused spirits.
Leo and Luna defeat Devack, and he disappears, freeing all the trapped spirits. Ancient Fairy Dragon and Regulus give their thanks to Luna, and becomes cards in her deck. Luna places the Ancient Fairy Dragon card in the control unit, deactivating it. Making sure everyone is safe, Yusei decides to head towards Kalin. Hearing about Devack’s defeat, Roman sways Greiger over to his side, and executes him in order to transform him into a Dark Signer.
Crow uses his Duel Runner’s modifications to survive Greiger’s attack. Yusei decides to jump into the geoglyph in order to discover who was dueling, and is shocked to find Greiger is a Dark Signer. Yusei tries to calm both of them down, but neither refuse to let up. Crow recalls that he had no friends when his father died, but thanks to finding some Duel Monster cards, he was able to learn how to read and make friends with other duelists, including Yusei and Jack, and soon grew to take care of others in the same way…
Greiger summons his Dark Synchro, which is Dark Flat Top, which allows him to special summon another Flying Fortress SKY FIRE, and then attacks Crow with it, which reduces Crow's life points to down 100. Crow crashes, but remains determined to win, and gets back into the game. Using a pot luck with his trap, he manages to defeat both monsters, but this in turn, allows Greiger to summon his Earthbound Immortal, Chacu Challhua. Crow manages to Synchro Summon Blackwing - Silverwind the Ascendant, and prepares to destroy Chacu Challua with its special ability, but then, he, Yusei, and Greiger notice that the souls used for its Chacu Challhua's summoning were the people of his village, and Greiger's siblings. Realizing it was the Dark Signer's fault, and not Goodwin's, Greiger wants to stop the duel, but the Earthbound Immortal refuses to give up, and takes over his body. As he struggles to regain control, Greiger asks Crow to finish the battle.
Yusei finally catches up with Kalin and start what Kalin calls 'The Last Duel of the Enforcers'. Yusei hopes that this duel will rekindle their friendship. After the Enforcers took over the Satellite, Kalin kept looking for enemies. When those enemies started including young kids, Crow and Jack left the team, leaving just Kalin and Yusei. When Security shows up in Satellite with Duel Runners and Kalin plans on destroying them, Yusei also quits the team. Kalin decides to attack Security, getting their attention by blowing up some confiscated Duel Disks. When Yusei, Jack and Crow catch wind of Kalin's actions, they go to look for him and find him cornered in a building ready to stand off against Security. Back in the present, Kalin summons his One-Hundred Eye Dragon and begins to utilize his Handless combo.
Yusei defeats One-Hundred Eye Dragon, but is fully aware that it allows Kalin to draw his Earthbound Immortal to his hand. Back in the last days of the Enforcers, in a flash-back of Yusei's memories, Yusei, Jack and Crow try to talk sense into Kalin, and they all end up running away from Sector Security. One Sector Security officer pins down Kalin, but he manages to jump on his Duel Runner, causing him to crash with a bad head injury. He tries to finish him off but Yusei stops him. Yusei tries to pose as the leader of the Enforcers in order to protect Kalin, but the chief of Sector Security at that time had already figured it out that Kalin was the real leader of the enforcers, and Kalin becomes furious when he sees his hand on Yusei's shoulder, thinking Yusei had ratted him out. Kalin then gets harsh treatment in prison, losing his deck, and he was eventually convinced by the voice of Roman to become a Dark Signer.
With Kalin and Ccapac Apu defeated, all the Satellite residents are returned. Just then, Roman uses one of his dark spiders to possess Trudge and talk to Yusei, coaxing him to find him at the Original Ener-D Reactor, challenging him to a duel. Lazar is seen talking to a mysterious figure. Goodwin goes to meet with Roman. Roman is shown with a shadow duel disk, and challenges Goodwin to a duel, as part of a promise they made. Yusei, Luna, Leo, and Trudge traverse down the crater, whilst Crow, who notices the army helicopters, takes a different route. Yusei encounters Roman on a bridge, who activates an explosion, causing a flux of Ener-D to appear underneath them. They start to duel and manages to attack Roman with Junk Warrior, although this in turn allows Roman to summon Earthbound Immortal Uru. Roman continues to put pressure on Yusei and manages to bring his life points down to 100.
After bringing Yusei's life points down to 50, Roman begins to tell him of what happened 17 years ago between him, Rex and Yusei's father. They were working on the Original Energy Reactor, but Professor Fudo wanted to stop the project when it started to look unstable. Roman had decided to travel to the Nazca lines, where he encountered a mysterious person, claiming to be from Yliaster, who knows about Roman's birthmark. The mysterious man convinces Roman to look into the light coming from the reactor, where he is struck by dark energy and is shown the history of the Earthbound Immortals and the mighty powerful Crimson Dragon. Meanwhile, Crow finds Rex, who explains that Professor Fudo was betrayed by Roman. He shows off four Dragon cards, but Professor Fudo manages to escape with three of them, but got severely injured in the process and entrusts the cards to Rex.
With Roman's defeat, all the Satellite citizens, including Martha and Rally, are returned. Jack finally meets up with Carly, but she is reluctant to be helped and challenges Jack to a Turbo Duel. Initially, Jack is reluctant to fight and takes a lot of damage, but he starts to fight back, as he does not believe Carly is a person who would hurt people. Carly traps Jack in a vision where he is transformed into a Dark Signer by Carly and becomes destined to destroy the Crimson Dragon by her side. However, noticing Carly's glasses, Jack breaks free of this vision, and decides to fight for what Carly truly desires. Meanwhile, Yusei finds himself in a strange place surrounded by the spirits of those who died in the Zero Reverse incident. Due to Yusei's connection to the incident, they start to attack him, but he is rescued by a strong white light and the voice of a familiar figure.
Jack activates a Trap that lets Carly choose the outcome. He manages to break through to Carly and she makes the right choice. However, the Earthbound Immortal takes over her body, forcing her to continue the duel. Jack brings out his Red Dragon Archfiend in the hopes of freeing her. Meanwhile, the mysterious spirit reveals himself to be Yusei's father, who returns him to the real world. Carly summons out her Earthbound Immortal - Aslla Piscu, but Jack manages to stop its attack. Jack expresses his feeling for Carly, and then he takes the marks of the other Signers, gives him the Seal of the Crimson Dragon. Hearing the real Carly's pleas to end the duel, despite his objections, Jack synchro summons Majestic Red Dragon. Jack hopes to end the duel in a tie, taking him down with her, so that he can still be with her, but Carly activates a trap card so that only she would lose. Jack is able to do nothing but hold Carly tight, as she disappears into the Netherworld.
Akiza and Mina arrive at an abandoned amusement park where Ccarayhua's control unit is, shortly followed by Yusei's group, and a man claiming to be sent by Goodwin. Misty traps Akiza in a Hall of Mirrors, actually dueling her through the mirrors. She uses cards that block off drawing cards from the deck, and also shows Akiza the events involving Misty and her brother, Toby, who apparently met her at Arcadia Movement. Yusei is led to a room where Mina is found unconscious and is attacked by the man who turns out to be Sayer, who had survived his duel with Carly, and is determined to reclaim Akiza. He uses his psychic abilities to knock Yusei in a cage with Mina as it slowly fills with water. Trudge eventually finds them and tries to free them. Akiza is shown the moment where Toby was killed, which led Misty to become depressed and crash her car, transforming her into a Dark Signer.
With Akiza's dormant physic abilities fully awakened, Misty activates her geoglyph. Trudge manages to free Yusei and Mina and Yusei goes to join Luna and Leo. Learning about Akiza's current state, Yusei goes to face Sayer, who reveals he is controlling her mind and was responsible for Toby's death. Misty summons out her Earthbound Immortal Ccarayhua. Sayer talks about the experiments he performed on Toby seeing that he did not have ultimate psychic powers sent him to an unknown location that not even he knows about. However, Yusei revealed he had activated an intercom on his duel disk, letting Misty know what Sayer had told him. Angered, Misty gets Ccarayhua to eat him, freeing Akiza from her trance. Misty apologizes to Akiza, but the Earthbound Immortal forces her to continue dueling. Akiza defeats her, setting her free, which results in her being sent to the netherworld. The New Domino City residents return, but a Dark Signer mark, the mark of the Condor appears in the sky.
As the Condor geoglyph shines in the sky, a massive monster emerges from the Original Ener-D Reactor and heads towards the Condor geoglyph over New Domino City, which was the King of the Netherworld. The Crimson Dragon appears and sends everyone to the front of a temple (the Altar of the Dragon Star), where they find Goodwin, who reveals himself to be a Dark Signer. Then, he transfers Roman's mark of the Dragon Head from a canister to his left arm, destroying the metallic arm that was covering it at the same time. He challenges Yusei, Jack and Crow to a Turbo Duel in the air. Goodwin reveals that he lost the duel with Roman prior to his battle with Yusei on purpose, and became a Dark Signer in order to end the pointless cycle. He summons out both a Synchro monster; Sun Dragon Inti, and its Dark Synchro counterpart; Moon Dragon Quilla. He also reveals he was the Legendary turbo duelist who constructed and flew across the Daedalus Bridge.
After being dealt some direct damage due to the cooperative efforts of Yusei, Jack and Crow, Goodwin is able to summon his Earthbound Immortal - Wiraqocha Rasca, absorbing the souls of New Domino City. Then, the King of the Netherworld spouts forth several beasts that attempt to attack the players. However, they are saved by Black Rose Dragon and Ancient Fairy Dragon. Crow sacrifices himself by playing a trap card in order to protect Yusei from Wiraqocha Rasca's special ability, and falls unconscious. Goodwin coaxes Jack into attacking him, but after he gives in and loses some life points, Goodwin's statement of becoming a dark signer causes Jack to remember what Carly taught him and decides not to do things his old fashioned way anymore. Goodwin laughs at the idea of the bonds of true friendship and love, saying that destiny is all that there is.
Goodwin reduces Jack's life points to 1, and gets the King of the Netherworld to attack him, causing him to crash. Yusei's life points get reduced to 1 too, before he summons his Stardust Dragon and takes advantage of the traps Crow and Jack placed beforehand. As Yusei tries to reach Goodwin, which he successfully does, he regains the Signers' marks from him. Furthermore, Yusei gains Roman's mark of the Dragon Head, and the mark of the Tail that Yusei used to have transfers over to Crow. Yusei then takes the marks of the other 4 Signers, and gains the Seal of the Crimson Dragon. Then, he summons the Majestic Star Dragon and destroys Earthbound Immortal Wiraqocha Rasca, which defeats Goodwin. Then, the Crimson Dragon envelops the Majestic Star Dragon, infusing it with the power of the Crimson Dragon, and dives into the King of the Netherworld.
Six months after the battle between the Dark Signers and the Signers, a large stone tablet falls (which is Machine Emperor Wisel Infinity's tablet) from space and lands on Earth, just outside of New Domino City. Whilst investigating it, Lazar encounters three people from Yliaster, who are Jakob (the leader), Lester (self-appointed sub-leader), and Primo (the lowest-ranking member). Lazar questions them about their intentions, but after being reminded by Primo that they were his leaders, and a brief outburst in which Primo points the tip of his sword at Lazar's neck, he quickly submits to the trio, and turns over the leadership of New Domino City to them. Then, Primo tells the other members of the trio that he was going to take his Machine Emperor out for a "test drive." A day later, Sector Security investigates a turbo duelist named Ghost, who is attacking Turbo Duelists, and "stealing" their Synchro Monsters, at night.
Yusei summons out his Stardust Dragon and deals some damage to Ghost. However, Ghost uses his Machine Emperor Wisel Infinity's special ability to absorb Stardust Dragon, which causes Stardust Dragon's attack points to be added to Wisel's, boosting its attack points from 2,500 to 5,000. Yusei puts up a good defense, but finds himself pressured. After hanging on for a while, Yusei remembers that he has a second chance, and uses Speed World 2's effect the Crimson Dragon's power to draw another card during his draw phase, which grants him the tuner monster Majestic Dragon, and he is able to retrieve Stardust Dragon using the trap card Syncro particle, and summons the Majestic Star Dragon, and then attacks Wisel Top, resulting in the destruction of the rest of the Machine Emperor, defeating The Ghost. The Ghost then crashes into a forest, and one of the 3 emperors of Yliaster, Primo, retrieves Ghost's duel disk, and his own Wisel deck from The Ghost's duel runner.
As Yusei and Crow work on their new engine, they are visited by Leo, Luna and their classmates, including the timid Sly, who is nearly tempted to steal Stardust Dragon. Yusei is asked by the Academy's principal to fix something, which turns out to be the head instructor, Rudolph Heitmann, who is threatening to expel Leo, Luna, and their friends for using low level monsters. Yusei arrives, and challenges Heitmann to a duel, in order to stop them getting expelled, and to prove the strength of low level monsters. Heitmann manages to summon three Ancient Gear Golems on his first turn and deals a lot of damage. Yusei summons out Stardust Dragon, but sacrifices him to summon out several Tuner monsters, which belong to the relevant students. Yusei manages to use them to defeat Heitmann, who learns his lesson, and withdraws the expulsions. As Yusei leaves, Sly contemplates to steal Stardust Dragon. Fortunately, he will never get that chance.
Yusei, Jack and Crow pay a visit to Martha and Blister, where Blister talks to them about the asteroid crater. Crow is asked to retrieve an old man named Bashford who refuses to leave his house due to family ties. However, the route to his house is filled with booby traps. He ends up on top of an old-fashioned Dueling Arena (which Bashford had built himself, in hopes that his son Koki would return and duel him), (Dueling Arenas were first used, in the first season of Yu-Gi-Oh! Duel Monsters) and challenges Bashford to a duel. He finds himself under pressure from his Bashford's Scrap-Iron deck, but he manages to make a comeback. The effects of the battle causes the duel arena and the house to collapse, but Crow manages to win the duel and help Bashford. Yusei manages to retrieve a family photo from the house before it collapsed. Bashford thanks them and returns to Martha's place.
Families find themselves under pressure from a loan shark named Don Pierro who takes their precious cards. Crow gets angry at Jack for drinking expensive coffee and suggests that he gets a job. However, his ego gets him kicked out of several jobs. He and Carly follow a boy named Marco to a shrine, where he leaves his cards that were deemed unworthy by Pierro. Jack decides to challenge Pierro for everyone's contracts, putting his Red Dragon Archfiend and Duel Runner on the line. Pierro puts pressure on Jack by implementing his Loan Tokens, damaging his life points. However, Jack manages to win using Marco's cards and destroys all of Pierro's loan contracts. However, he still can't get a job.
Whilst Leo, Luna and Dexter go wandering through a forest, Luna senses an atmosphere, drifts out of consciousness and follows it, despite warning from Kuribon and Regulus. When she awakens, Luna encounters a boy named Hayley who is looking after a doll representing his sister, Claire. When they notice she has gone missing, Dexter goes to Yusei for help whilst Leo chases after her. When Leo approaches the house, Hayley feels threatened and goes to duel him. Leo notices the damage Hayley is dealing is similar to a Psychic Duelist's, and summons out his Power Tool Dragon. Yusei arrives and busts into the house and finds a load of people trapped inside cards. Meanwhile, Luna is able to talk with the spirit of Claire. Hayley summons out Hollow Ghost and deals some harsh damage to Leo, but Leo manages to turn it around and win the duel. It is revealed that Hayley had died along with his sister, but didn't realize it, which was what kept him there.
Yusei wakes up to find himself being carried away inside a truck after being ambushed by someone named Ichiro wanting to recruit him for the Grand Prix. When Jack, Crow, Akiza and Mina hear about his capture, they go to look for him. Akiza manages to locate the truck Yusei is captured in, and is surprised to find no one is driving it. Akiza uses her powers to break it open, but ends up trapped on their with Yusei when the truck speeds up. They escape, but are then challenged to a Turbo Duel by a mysterious rider. She brings out a fusion monster whilst Yusei responds with Junk Warrior, and Akiza finds herself moved from witnessing a Turbo Duel first hand. The rider then brings out her ace monster and reveals herself to be a woman named Sherry Le Blanc, hoping to recruit Yusei to her team.
The duel between Yusei and Sherry continues, with Akiza insisting that she stay and spectate. Yusei brings out Turbo Warrior and deals some damage, and eventually destroys her monster. However, it leaves him in a point where Sherry can win if she draws a Speed Spell, using Speed World 2's effects. Sherry then tells Yusei that she's entering the WRGP to avenge her parents who were killed by Yliaster. Just as Yusei is about to summon Stardust Dragon, Ichiro appears and tries to drop a truck on them. Akiza uses her powers to materialize Stardust Dragon and stop the truck, and Sherry's guardian, Elsworth, beats up Ichiro and his gang. Due to damage to the Duel Lanes, the duel is called off, but they promise to duel again. Akiza is left with a newfound respect for Turbo Duels.
Yusei has a nightmare about Stardust Dragon being captured by The Ghost, and of Sherry's offer. Wanting to learn to duel without relying on Synchro monsters, Yusei asks Jack to duel him. As they duel, they are being watched by a mysterious character (who is really Vizor). Sensing fear in Yusei after being attacked by Red Dragon Archfiend, Jack cancels the duel, saying that there's no way to win without Synchros (Vizor left by the time the duel was over). Later, everyone attends a premiere event for the WRGP, where the details for the tournament are shown. Lazar meets up with the group from Yliaster, who are using the tournament for their own gain. Just then, the party is crashed by a violent Turbo Duelist named Dobocle. Akiza stops him from wrecking the party, and the Yliaster trio become interested in her powers. Dobocle tries to escape, but is attacked by another Ghost, who is really Primo, because he got sick of Dobocle's actions.
The mysterious dueler, known only as Vizor, decides to train Yusei to face Ghost. He starts off by racing him, testing Yusei's ability to handle mach speeds. Once he cleared that, the duel begins, with Vizor managing to summon two Synchro Monsters in his first turn. Before Yusei is able to counterattack, Vizor speeds up to mach-speed, performing an Accel Synchro with his two monsters to form a new one. Yusei responds by summoning Drill Warrior, and powers it up later, though Vizor decides to take direct damage and lose the duel, instead of damaging his monster. The Yliaster, who had been watching the duel, become curious about Vizor's actions.
Wanting to understand what Turbo Duelists feel, Akiza decides to apply for a Turbo Duel License. Despite initially making lots of mistakes, her determination, along with Yusei's tutelage, allows her to pass the initial exams. Yusei also takes her rollerskating to help her learn how to ride backwards. Yusei then builds her a proper Duel Runner, with the help of Jack and Crow. To obtain her license, she has to beat Trudge in a qualification duel, though she initially has trouble getting to grip with Speed Spells, and her Black Rose Dragon gets beaten. However, she manages to turn it around and summon her Splendid Rose. Some guys, who were furious about losing to Akiza in the initial exams, activate a trap to trip Akiza up. However, using the skills Yusei taught her, she evades the trap and defeats Trudge. With her license earned, Yusei welcomes Akiza to the world of Turbo Dueling. Meanwhile Jack beats up the guys that activated the trap and calls Akiza his friend.
Jack and Carly investigate some Duel Runner thefts. While chasing after a group of them, one of the members, who is actually an undercover agent named Kaz, gets injured. Jack feels responsible for causing the accident, and tries to investigate the matter himself, but is ganged up on and knocked out. He doesn't give up, and soon comes across the entire gang again, where he is once again beaten. However, he was able to place a tracker on one of the members, and finds their hideout, which is located on a large ship. The boss, Syd, challenges Jack to a duel in which the loser is thrown into a crusher. Syd gets the upper hand early on, and despite Jack summoning several monsters, he still finds himself countered. It is soon revealed that their hideout is on a tanker, which has sailed out of range from Sector Security.
As Yusei and Akiza have a practice Turbo Duel, Leo ponders how he'd fare as a Turbo Duelist. Meanwhile, the Yliaster trio discuss their plans involving the Crimson Dragon, and another tablet crashes into the earth. Later at Duel Academy, a boy named Lester (one of the Yliaster emperors in disguise) enrolls into the school hoping to find out more about Luna, who soon falls in love with Lester. Leo gets annoyed with him asking her so many questions, so Lester uses an illusion to separate him from Luna, and takes her to his mansion. When Leo realizes he's been tricked, he sneaks into the mansion, where Lester shows off an Ener-D powered skateboard that can be used for Turbo Dueling, called a Duel Board, which he gives to Luna. Feeling jealous, Leo begs Yusei to build him his own Duel Board, and spends several days practicing. Luna later joins him in practicing, but they are attacked by another Duel Skater (who is really Lester back in his original dueling outfit) who traps her in a duel.
Realizing Luna and Leo are in trouble, Yusei, Jack, Crow, and Akiza head off to find them. Luna summons out Ancient Fairy Dragon, but it is soon absorbed by Machine Emperor Skiel Infinity. As Yusei and company can only watch, Leo recognizes his opponent as Lester, but Lester states the recognition of his identity has already come to late for them to do anything about it. Luna soon takes some damage in order to protect Leo from Skiel's attacks. Leo summons out Power Tool Dragon, and using traps and monster effects, manages to retrieve Ancient Fairy Dragon. Lester upgrades Skiel and defeats Leo, knocking him off the bridge, but the Crimson Dragon appears and saves him. Luna's counterattack fails, but her Duel Monster spirits prevent her from being hurt, after she loses. When the group try to investigate Lester, they find his mansion gone, and that no one at Duel Academy remembers him. Spurred on by this attack, Yusei becomes determined to learn the Accel Synchro.
Recap episode. As Yusei tests out his engine, Jack and Crow look back on his previous battles to try to understand him. When they meet up with Yusei, he suspects that Yliaster is the one behind Ghost and is planning something big with the WRGP. He also tells Jack and Crow about Accel Synchro. They become determined to learn this new move, which would require a new engine. Meanwhile, a mysterious person washes up on the beach.
Trudge and Mina invite Yusei, Jack and Crow for a fancy dinner, albeit with a motive. They want them to look after Bruno, an amnesiac who recently washed up onto New Domino City. Whilst they initially refuse, they soon discover he is an extremely talented mechanic. Yusei becomes particularly interested in him, as he could help build the engine he needs to perfect Accel Synchro. However, as he spends more time with him, his friends start to get a bit jealous. Yusei and Bruno manage to complete the program needed for his new engine, but it is stolen overnight. Finding a fingerprint on a cup ramen packet, they decide to hack into the Security network to find the culprit, having to complete a puzzle duel in order to gain access. Jack and Crow have trouble going up against Mirror Force, but Bruno uses his intuition to figure out the correct solution. They discover that the matching fingerprint belongs to Lazar.
Yusei, Jack, Crow and Bruno decide to trail Lazar, who had stolen their program for Primo. Noticing he is being followed, Lazar heads to the mall where Yusei and company manage to apprehend him, but he makes a break for it. Lazar manages to lose Jack and Crow using holograms, though Bruno manages to figure out, and he and Yusei follow Lazar to a complex. Lazar gives the program to Primo, who then notices they are being followed and sets off the alarm, separating Yusei and Bruno. Primo activates a dueling Guard Robot filled with Yusei's battle data in order to stall Yusei whilst he installs the program into hundreds of Duel-Bots, collectively called the Diablo. Bruno almost stumbles upon this until he is knocked out by Primo and thrown out of the secret factory when he triggers a lost memory. Meanwhile the Guard Robot uses its high prediction capabilities to block off Yusei's high level monsters and special summons, putting him in a tough spot.
Jack and Crow arrive at the complex only to find themselves locked out, so they sneak in via a ventilation shaft. As Yusei continues to struggle against the Guard Robot, Primo completes their program's installation into the Ghosts, although one of the other emperors of Yliaster, Jakob (the leader), is curious and suspicious of his actions. With his objective complete, Primo starts a self-destruct countdown and leaves using his power, giving Yusei just 10 minutes to win his duel and escape. Jack and Crow join up with Bruno who, reluctantly, have to escape ahead of Yusei. As time is about to run out, Yusei manages to use his monster's abilities to block off the Guard Robot's Lock Deck and summon Stardust Dragon to win the duel. As the complex explodes, Lazar uses his tricks to save Yusei and warns him not to delve any further into the matter.
Sector Security bursts in with a warrant for Jack's arrest. Mina and Trudge show footage of something similar to Jack's Duel Runner causing other people to crash in duels using Red Dragon Archfiend. Yusei and company recall that earlier, Jack had fallen out with them over sticking to his usual plays. Jack still denies committing any crimes, and Crow doesn't help. As a result, Jack is arrested and sent to jail. When news spreads, everyone else has a hard time believing it. Later that night, an electronic bug breaks open Jack's cell, allowing him to escape. However, he then runs into an identical Jack Atlas riding an identical Duel Runner and behaving like Jack in his "Duel King" phase (from Season 1), and is challenged to a Turbo Duel. Jack draws a Tuner Monster that can summon Red Dragon Archfiend, but refuses to use it due to the earlier argument, and summons Exploder Dragon instead. He initially gains the upper hand, but is shocked to find his tactics dubbed weak by the impostor.
Wanting to find out the truth behind Jack's alleged crime spree, Carly meets with a pair of hippies who caught a picture of two of Jack's Duel Runner. She replays this to Yusei and Crow, who search the crash site only to find one of Jack's cards. The real Jack is trapped in a virtual prison of sorts, made by the Yliaster trio, forced to watch his impostor ruin his reputation. Yusei and Crow catch up with the impostor, but are attacked by his thrusters. Hearing his friends kindness, Jack breaks free from his imprisonment, and catches up with his impostor for a rematch. This time Jack learns from his mistakes and uses the right Tuner Monster to summon Red Dragon Archfiend. The impostor then summons his own Red Dragon Archfiend but Jack manages to destroy it. However, the imposter then manages to revive it, and summons two more Red Dragon Archfiend copies. Jack manages to survive his attack and is granted the power to summon Majestic Red Dragon by his Mark of the Dragon.
Yusei's landlord, Zora, is depressed because the city wants to replace the broken cuckoo clock on her clock repair shop. Later, the gang are visited by Zora's son, Lynden, who has returned after three years of training to fix the clock. When he goes to see Zora again, she is not happy to see him, since he was the one who broke the clock in the first place. Before he can run off, Crow challenges him to a duel, forcing him to apologize if he won. Crow runs into a bit of trouble with Lynden absorbing one of his monsters and summoning out his Clock Knight monsters that rely on coin tosses, but soon comes back with his Blackwing Armor Master. Lynden tries to back off from the duel, but Crow tells him he needs to stop running away from his problems. Lynden summons a Time Wizard he got from his late father to destroy Crow's monster. Crow decides to take the damage instead of activating his Mirror Force, since Lynden had realized he can't keep running away regardless of his victory.
Yusei arrives in a desert town called Crash Town, after receiving a letter from a woman named Barbara that Kalin was in trouble. She explains that in this town, there are battles at sunset between the Malcolm family and the Radley group. Yusei is surprised to find Kalin siding with Radley's group, and notices a change in his personality. Kalin uses his Handless Combo and quickly defeats Malcolm's challenger, who is taken away to become a slave in the mountains. Yusei tries to reach Kalin, but he doesn't answer him. Barbara tells Yusei the only way to save him is to beat him in a duel to separate him from the Radley family. Yusei decides to join up with the Malcolm family, earning his place by defeating three of Malcolm's men in one turn, with his Nitro Warrior.
Kalin still has memories of when he was a Dark Signer, and doesn't even find encouragement from the words of a young boy. Barbara mentions a plan involving using dynamite to aid Kalin's escape following their duel. During the next sunset, Yusei duels Kalin, who quickly puts his Handless Combo into effect. Kalin laments that he was never able to forgive himself for the actions he took as a Dark Signer, and has been looking to die, saying he'll be satisfied if Yusei defeats him. Yusei manages to take the lead, but Kalin still has tricks up his sleeve.
Kalin summons Infernity Doom Dragon, while Yusei summons Stardust Dragon. Using an equip monster, Yusei manages to defeat Kalin. However, Barbara betrays Yusei, attacking him whilst Kalin is taken away. The Malcolm family's top dog, Lawton, then appears and duels Radley, beating him before he even gets a turn. Barbara and the Malcolm family had used Yusei all along to remove Kalin from the Radley group so they would be easy prey. Yusei, along with Kalin and Radley, are taken to the mines and given shock collars. Yusei finds a means of escaping, but Kalin still refuses to be helped. Meanwhile, Nico and West sneak off with Yusei's Duel Runner.
Yusei knocks out Kalin, so they can escape, stumbling upon a graveyard of lost duelists. They then encounter Nico and West who have Yusei's Duel Runner, and learn that their father is still inside the mines. Lawton then finds them, so while Kalin and the kids look for their father, Yusei distracts him with a Turbo Duel. Lawton immediately summons Gatling Ogre, but Yusei's manages to delay its One Turn Kill ability. However, Lawton soon replaces it with Full Armor Ogre. Meanwhile, Kalin and the kids escape on a mine cart and arrive in a different mine. They become surrounded, but Kalin fights them off as West and Nico find their father, setting off to escape again. Yusei manages to beat Full Armor Ogre, but Lawton manages to resummon Gatling Ogre, putting Yusei in a position where one card could mean his defeat.
As Kalin escapes with the kids and their father, Sergio, the pursuers start activating the father's shock collar, but Kalin manages to stop it though nearly falls off the kart in the process. Yusei manages to avoid losing to effects, but Lawton instead summons a more powerful monster. Kalin's group are directed towards a deadly gap, so West and Nico's father jumps to change the tracks to safety, and Sergio falls into the abyss in the process (and dies). Yusei manages to summon Drill Warrior from his graveyard, and Kalin knocks into Lawton before he can respond to it. Lawton then throws some dynamite which sends everyone flying, with Yusei and Kalin falling into a canyon. Lawton kidnaps Nico and West, and along with Barbara overthrows Malcolm. As Yusei and Kalin visit the father's (Sergio) grave, his duel disk reacts to Kalin, who decides to fight with Yusei.
Barbara starts forcing members of the Malcolm family to duel each other to provide new workers for the mines. Yusei and Kalin arrive and challenge Lawton to a duel for Nico and West's freedom and to liberate the town. Lawton gets a handicap to start with 10 cards, giving him easy access to Gatling Ogre's ability. Kalin stops Yusei from negating Galting Ogre's effect and gets attacked. However, he has a special monster, Infernity Zero, whose ability allows him to remain in the duel even with 0 life points, though he will lose if he gains 3 Doom Counters. Lawton manages to destroy the card Yusei used to negate Gatling Ogre's effect in their last duel, but both he and Kalin manage to defend against Lawton's attacks, and Kalin manages to bring up his defense.
Yusei summons his Nitro Warrior and beats Gatling Ogre, dealing some damage to Lawton. However, Lawton summons out Long Barrel Ogre, and Kalin gains another Doom Counter, but Yusei sacrifices his Nitro Warrior to keep Kalin in the game. Kalin and Yusei both summon out their Infernity Doom Dragon ,and Stardust Dragon, but their attacks don't get through. Barbara threatens to harm Nico and West if Yusei and Kalin don't surrender, but the Malcolm family stand up against her. Lawton tries shooting his Shock Gun at Kalin, but is stopped by the arrival of Crow and Jack, who had brought along Sector Security to free all of the miners. Lawton sets off some explosions to escape, but Kalin catches up to him to finish the duel. Lawton makes an assumption about Kalin's cards, but he is defeated, thanks to the effects of Kalin's monsters. Lawton and Barbara are arrested by Sector Security, Crash Town is rebuilt as Satisfaction Town, and Kalin stays behind to look after Nico and West.
Sherry tries to get answers concerning the card her parents were killed over (which is the Z-ONE spell card). She decides the best way to figure it out is to use the Public Security Maintenance Bureau's super computer. The next day, Sherry and Elsworth set off a dummy bomb at HQ, causing everyone to evacuate. When they lock the building down, Yusei and Bruno are left inside, and they soon discover the two. As Bruno follows after Sherry, Elsworth blocks Yusei off, and challenges him to a duel. Elsworth summons his Driven Daredevil, which does great damage to Yusei during his counterattack. Sherry reaches the main computer, hoping to find out the meaning behind her card, but starts fighting Bruno when he shows up. Just then, Bruno's eyes start glowing red and he overpowers Sherry. Noticing her card, he stops attacking and helps her to analyze it. Yusei summons Stardust Dragon and beats Elsworth with a counter trap, and the two catch up to Sherry and Bruno.
Crow goes to visit the grave of Robert Pearson, the original owner of Crow's Blackwing Deck and the Blackbird (Crow's duel runner), who died in an unusual purple fire three years ago. Later, Bruno finds a sealed compartment in Crow's Blackbird that he can't access, which is preventing him from giving Crow's duel runner some upgrades. Crow is later approached by Trudge and Mina, who believe Pearson's death was caused by a duelist using a card called, Crimson Mephist, that dealt real damage, and sent people to the Netherworld. Crow goes to see another of his old friends, Bolton, to ask about the accident. Bolton agrees to talk, but only if Crow duels him, wanting the Black-Winged Dragon card he needs for a loan should he win, even though Crow doesn't know where it is. Crow tells Yusei about how he met Pearson after leaving the Enforcers. The next day, Crow and Bolton start their duel, and Crow has trouble fighting against Bolton's Anti-Blackwing deck.
As Crow continues his duel against Bolton, he makes a small comeback with his Blackwing Arms Wing. However, Bolton then summons out Crimson Mephist, revealing he was the one who killed Pearson. Pearson had refused to sell his Duel Runner rights for a large sum of cash, so Bolton took matters into his own hands. Crimson Mephist destroys Arms Wing and deals some real damage to Crow. As Crow wonders if he can win, he receives encouragement from the kids he's looked after. Crow's mark glows, which automatically keys in the password to unlocking the sealed compartment in Crow's Blackbird. And Black-Winged Dragon, which was hidden inside the compartment all along, reveals itself. Crow then summons it, and uses its special ability to defeat Bolton, who feels remorse for what he had done, and promises that he will change.
Yusei, Jack and Crow finally complete their new Duel Runner engines, and they name their WRGP team Team 5D's. They have a practice run on the WRGP circuit. However, Crow refuses to stop when the practice session is over, and causes one of Team Unicorn's members to crash. As a way of apology, Yusei accepts a supposedly friendly duel with their "best" duelist, Andre. Unbenownst to Yusei, the duel is really a means to learn his strategy. Andre gets a head start with his Green Baboon, before Yusei summons his Junk Archer. However, Andre responds by bringing out his Behemoth, putting Yusei in a tight spot.
Yusei manages to survive Andre's onslaught, but still takes a lot of damage to his life points, especially when Andre brings out his Synchro Monster. Yusei summons out Stardust Dragon and destroys his monster, but before Yusei can win using Speed World 2's effects, Team Unicorn's practice time ends, along with the duel. The next day, Sherry briefly visits Yusei to ask about the thing they both saw, and Martha's kids give Crow a banner they made. This inspires him to train, but he suddenly crashes and breaks his arm, leaving him unable to participate, so Akiza offers to take his place. Crow, whilst initially furious at the decision, offers to coach Akiza in her training.
The WRGP Preliminaries begin with Team 5D's facing against Team Unicorn. Jack goes up first in the hopes of putting his Power Deck against Andre, who uses an overboost system to turn the corner first, and take the first turn. Jack summons out Red Dragon Archfiend, but takes a lot of damage thanks to Andre's strategy. Andre than summons out Thunder Unicorn, which puts Jack in a tighter spot. Bruno notices a problem in Jack's Duel Runner, but Jack refuses to take a pit stop, and manages to destroy Thunder Unicorn. Yusei realizes that they had been tricked by Team Unicorn into using a Power Deck, but it is too late, as Andre defeats Jack using Speed World 2's effects, the force of which causes his Duel Runner to crash.
Despite his injuries, Jack gets up to push his Duel Runner to the end of the lap to pass the baton over to Akiza, managing to do so before they are knocked out. Akiza immediately summons out Phoenixian Cluster Amaryllis to deal some damage to Andre. However during the next turn, Andre manages to remove it and bring back his Thunder Unicorn. The next turn, Akiza summons out Black Rose Dragon and, to everyone's surprise, Stardust Dragon, which Yusei had given her. However, Andre ends the battle phase before Stardust can attack and uses Thunder Unicorn to beat it. Before Andre can use Speed World 2's effect, Akiza wipes out her own life points to revive Stardust Dragon, in order to pass it on to Yusei. As Yusei continues the fight, Akiza laments that she couldn't help much, but finds encouragement from her parents and the crowd.
Yusei manages to destroy Andre's key Speed Spell card, but in doing so allows Andre to activate that, despite knocking himself out, takes a huge chunk out of Yusei's life points. Yusei then faces Team Unicorn's next duelist, Breo, who soon summons his Synchro monster, Voltic Bicorn. He soon destroys it however in order to implement his deck destruction tactic.
