The storyline of Over the Nexus does not immediately tie into that of the anime, unlike the previous two games. The player more or less keeps to their separate plot until the story reaches the halfway point, where it starts using events from the WRGP arc of the anime. As EXVC cards are not present in the card database, the plot simply ends where Aporia would have been introduced into the story.
Chapter 1 - The Beginning - The Frontier Lands, Crash Town
The story starts in the deserted city of Crash Town. The player has a dream of becoming the best duelist, but they are awakened by Klaus, telling them that their dream won't be real and then Klaus goes to work on the mines. The player heads to Nico and West's hideout, where they duel to pass the time until the nearby card shop opens.
The card shop is hosting a Rental Deck Tournament, where participants face off using pre-made Decks. One contestant has yet to arrive and so the player fills in for them. After defeating all opponents, the player heads home, only to be stopped by Bronson, who was the tournament participant whom the player replaced. Bronson is soon defeated by the player, and remarks that the player has done well for winning in his place.
The Player goes back to his house. There, he finds Klaus, who is telling him that the next day the two must go shopping in Satellite.
Chapter 2 - The Encounter - Team Satisfaction
Before the player and Klaus leave for Satellite, Toru requests that the player help him purchase some Duel Runner parts.
After their arrival in Satellite, the player and Klaus go their separate ways to get what they need. The player is soon sidetracked when he/she meets a girl named Lilie who is looking for Crow. They find him, but Crow mistakes the player as a kidnapper and duels them. Lilie soon clears the misunderstanding and leaves with Crow.
The player then continues to look for Duel Runner parts, and meets Gordon, who recommends a shop. After making the purchase, Gordon ambushes the player and steals the parts. The player gives chase, only to be stopped by gangsters along the way. However, Team Satisfaction appears and engages the gangsters, allowing for the player to pursue Gordon and retrieve the parts.
On the way out, two of the Team Satisfaction members - Yusei and Kalin - introduce themselves to the player. Yusei checks the parts purchased by the player and realizes that they simply consist of junk stuck together. While Yusei goes off to get functional parts, Kalin heads back to the Duel Runner shop to get Toru's money back. The player also wishes to thank the remaining member, Jack. On meeting Jack, the player gets into a duel for sport, and soon gets friendly matches with the other members of Team Satisfaction.
With Yusei's recommended parts in tow, the player returns to Crash Town.
Chapter 3 - The Turning Point - Just Me and My Duel Runner
Back at Crash Town, the player hands over Yusei's parts to Toru. Toru notes that they are of much better quality than what he asked for, and begins work on the Duel Runner. The player also relays the story to Nico and West, and Toru arrives at the hideout to announce the completion of his Duel Runner. They all head to the outskirts of the town, where Toru drives his Duel Runner around and even lets the player attempt a test drive.
Soon, Toru declares that he will be moving out of Crash Town and into New Domino City. Klaus forbids the player to go along, saying that they would just waste their time there.
The next day, the war between Malcolm and Ramon escalates, and Nico is nowhere to be found. The player sets out to look for her and escort her back to his home, dueling through members of the warring factions along the way. With the siblings reunited, Klaus lets them stay for the night before getting them to their home. Klaus notes that the player has been improving and challenges him to a duel to ascertain it.
Having confidence in his grandchild's ability, Klaus reveals a Duel Runner hidden in the basement of the player's home. He mentioned that the player's parents were Turbo Duelists who lost their lives in an accident, resulting in his initial reluctance to allow the player to ride a Duel Runner. Using the Duel Runner, Klaus plans to move out of Crash Town with the player, Nico and West. However, Nico and West have to stay in Crash Town since their father works at the nearby mines there.
Chapter 4 - Completion - New Friends, New Partnerships
Klaus and the player arrive in New Domino City. There, the player meets a mysterious woman named Misaki who happens to know his/her name. Misaki duels the player to test their ability, and then leads them into her garage. There, the player meets up with Toru, who proposes that the three of them form a Riding Team. However, the player's current Duel Runner is in no condition for a Turbo Duel, and Misaki recommends that they replace the vital parts - the CPU, engine, and frame.
The player is first pointed to Bootleg for leads on Duel Runner parts. There, the owner offers information if the player solves three of his five Duel Puzzles. Upon completion, the owner points the player to Blister's apartment, where the player receives the Duel Runner's CPU. Blister mentions that thrown-out parts also can be found in the underground duel arena, which is where the player finds the engine.
Upon returning to Misaki's garage, Misaki says that she found a frame in a locked-out scrapyard. The player heads there, only to find Blister and Bolt opening the gate to the scrapyard. Despite the fact that the frame is about to be thrown out with the rest of the scrap pile, Bolt is reluctant to give the frame away, and proposes a Tag Duel for the frame.
With the Duel Runner complete, Toru and the player decide to test it out the next day via a Turbo Duel. After the duel ends, Primo sees the Grand Design appearing. Lester and Jakob say he must have imagined the event, as it is not time for that yet. Back at the highway, Breo appears, infuriated at the player for using his practice course. He challenges the player to a race, and backs down when defeated. However, Toru and Misaki have pushed their Duel Runners too hard during the race and thus their machines need repairing.
Just then, Crow bumps into the player, remembering him/her from their meeting at Satellite. Crow offers to get Yusei to fix the Duel Runners. While Yusei prepares the parts for repairs, Klaus rushes in with a message of distress from Nico and West. As only the player's Duel Runner is functional, the player first sets off to Crash Town to settle the situation.
Chapter 5 - Going Home - Memories Long Past and a Hand of Hope
Back at Crash Town, the player finds West and Nico at their hideout. The kids' father, Sergio, is working under Malcolm, and he never come back home. The player decided to pay Malcolm a visit to ask about the kids' father. At Malcolm's house, the player duels with Seluga in order to meet Malcolm. Malcolm, having watched the duel, tests the player himself and is impressed with the player's skills. He offers the player to duel under him in exchange for information on Sergio.
The next day, the player duels against Kalin, who is working under Ramon. After defeating Kalin, Yusei rushes out from the flower shop, telling them that they must escape the town. He requested help from Barbara. However, she revealed that she is in fact working with Malcolm, and has no intention of helping them. Upon hearing that Lawton is returning from his training, Ramon leaves. Yusei, Kalin, and the player are captured and sent to work in the mine so that they will not disturb Malcolm's control over the town. While there, they meet Sergio. Yusei finds a path that leads outside, and the group decides to escape from the mine. While escaping, Sergio saves Kalin from a stray rockfall, and falls into the abyss of the mines.
The trio meets Toru and Misaki after escaping from the mine. They inform the trio that Malcolm and Radley are at war. They then return to town in an attempt to quell the warring factions and look for the kids. After defeating Malcolm and Radley, Lawton appears and seizes control of the entire town. While the player and Kalin team up to defeat him in a duel, Lawton states that his loss makes no difference to the fact that he now has the whole town under his command.
Lawton attempts to rally his lackeys, only to find that they have all been beaten by Jack and Crow. He attempts to escape, only to be cornered by Toru and Misaki. Lawton, along with the other gangsters of Crash Town, are arrested by Trudge and Mina. Peace is restored to the village, and it is renamed Satisfaction Town.
Chapter 6 - Changes - Preparing for the Tournament and a Looming Shadow
The player, Toru and Misaki decide to take part in the WRGP. After deciding on a team name, they start maintenance on their Duel Runners. They found the same tools left behind by Yusei, and ask the player to return the tools. After returning the tools at Yusei's garage, Trudge and Mina pay Yusei a visit, as well as informing them about a mysterious turbo duelist Ghost. Yusei also introduces the player to Bruno.
After returning to Toru's garage, the team decide to test run their duel runner on the highway. However, the player encounters Ghost, and is forced to duel him while witnessing the power of Meklord Emperor Wisel. After winning, Ghost leaves the highway. Toru and Misaki warn the player to be careful.
Back at the garage, Crow introduces the team to Akiza, a newly initiated Turbo Duelist. They decide to have a few Turbo Duels with each other to let Akiza get the hang of Turbo Duels and her Duel Runner. While racing, a mysterious Turbo Duelist appears and tells the player that he/she has to evolve his/her Synchro Summon in order to defeat the Meklords. The Turbo Duelist then leaves without a word.
A few days later, Klaus complains about Toru's duel runner being noisy at night. The player goes off to investigate, only to find that Toru's Duel Runner is stolen. As the player relays the information to Yusei, he/she also finds out that Jack's Duel Runner is also stolen. Trudge and Mina inform the player of a sudden recent surge of Duel Runner parts on sale in Satellite, and the player sets off to investigate this.
He/she goes to the shop that sold him/her fake parts years ago, and duels the shopkeeper for information on the Duel Runner parts. He reveals that he bought the parts from Syd. At the port, the player overhears two of Syd's henchmen, Ida and Kameno talking about selling Jack's duel runner. Upon getting discovered, Jack arrives and helps the player defeat Syd and his henchmen. Syd tries to escape, but is thwarted and taken away by Mina and Trudge. They help to send Toru's and Jack's Duel Runners back to their garage.
Several days later, at the garage, Akiza arrives, looking for opponents to spar with. Misaki, however, is busy working on a new duel runner program. Akiza mentions that Bruno can help with his skill in programming, and expresses her annoyance at how Yusei has been dedicating his time to working with Bruno. Bruno agrees to assist with the program, and Yusei goes off to apologize to Akiza. As the player leaves, he/she meets Leo and Luna who happen to be looking for Yusei. Jack also mentions that Bruno has finished the program for his team.
The next day, the team decide to test the new Start Dash program at the combat lane. However, Jack shows up and forces the player to duel with him. After defeating him, it is revealed that the opponent is actually an imposter. The real Jack shows up and decides to hunt down the culprit.
Meanwhile, the Grand Design appears, and the Three Pure Nobles start to put their plan into action.
Final Chapter - To the Future - State of the WRGP and the World
The WRGP finally begins. In the first match against Team Unicorn, Breo defeats Toru by causing him to Deck-out. Misaki defeats Breo, but is defeated by Andre. The player then duels with Andre, and eventually Jean, and win the first round. The next day, the team goes against Team Catastrophe. Toru defeats the first duelist, Hans. Hermann, the second duelist, causes Toru to crash his Duel Runner. The player take over Toru, and defeated Hermann and the last duelist, Nicolas. Nicolas, however, tries to crash the player's Duel Runner, but he ends up crashing instead due to Primo.
The next day, Yusei congratulates the team on winning the first two rounds. He informs the player that Crow is practicing on the highway, and the player goes to practice with him. While riding on the highway, the player is transported into a desert with a large stone tablet is in front of him/her. After hearing a voice, he/she is given a "Blank Card". The Emperors notice this and wonder why the player would be subject to this.
The next day, Toru and the player are training when suddenly the city is invaded by many Ghosts. Misaki, sensing this, transforms into the mysterious Turbo Duelist from before and drives off. The player is being chased by a group of Ghosts, who activates the Battle Royal mode. After escaping from the group of Ghosts, the player meets Primo, who combines with his Duel Runner and challenges the player, while the player's companions step up to take care of the remaining Ghosts. After Primo is defeated, Jakob and Lester appear to the player, Yusei and Jack, and explain their intention of changing the future by destroying New Domino City. When Jack and Yusei express their discontent with this future, Jakob tells them to continue winning in the WRGP to see if they truly can avert this fate.
Back at the garage, the group finds out that the history had been altered. A new team, Team New World, is participating in the WRGP. With Toru and Crow injured from the Diablo attack, Yusei, Jack and the player form a new Team 5D's to participate in the WRGP.
During the day of the WRGP, the team is up against Team Sherry, a team with only two members. Sherry LeBlanc, the team leader, explains that she is after Yliaster for revenge. After Yusei is defeated by Elsworth, the player takes over for him and defeats both Elsworth and Sherry. Sherry decides that her desire for revenge alone is not enough, and encourages Team 5D's to take down Yliaster.
Before the next race, the player is greeted with a heated argument between Jack and Harald. Harald mentions that his team, Team Ragnarok, are destined to defeat the Yliaster, but they refuse to work with Team 5D's due to Yusei's past. The team faces off against Team Ragnarok. Dragan manages to defeat Jack. The player, however, defeats Dragan, and eventually Brave and Harald, thus defeating Team Ragnarok. Harald, too, encourages Team 5D's to take up their cause of defeating Yliaster.
The next day, the final round of the WRGP against Team New World begins. Primo defeats both Yusei and Jack without even taking a scratch. When it is the player's turn, the "Blank Card" turns into three Synchro Monster Cards: "Ally of Justice Decisive Armor", "Trident Dragion" and "Trishula, Dragon of the Ice Barrier". The game then takes the player to the Deck Edit menu, granting them the opportunity to add these new cards to the Deck. With Team 5D's cheering on, the player continues to defeat the entire Team New World on their own.
The player reappears with Lester and Primo inside the room inside the Divine Temple in which Z-one is seen in in the Yu-Gi-Oh! 5D's anime. Having seen humanity's potential, Team New World resigns from their plan to destroy New Domino City and tells the player to carve their own future. The player reappears in the pits, with the Blank Card returning to its original state. Then, after discussing the future with Yusei and Jack, Team 5D's does a victory lap.
The game skips forward a few days and the player's WRGP team are talking about their futures. The player goes to the pits, where Toru begins dueling Crow in an exclusive final round of the WRGP. Misaki turns to the player and a picture of Misaki smiling appears on the top screen. She thanks the player for saving the future - The credits roll, and the game ends.
In the 5D's Story Mode, some duels have special rules, a condition that is applied to both players or one of them. The following Special Rules are applied:
- Lawton: The player faces him with Kalin Kessler as the player's partner. Lawton starts with 10 cards in his hand.
- Ghost: Must be defeated after he Summons "Meklord Emperor Wisel ∞". He will always go first.
The WRGP rules are similar to the anime. When a player loses, the next player will take over and retain the same cards on the field. The winning player's Deck is not shuffled, meaning the first Duelist in each WRGP Duel will always draw the same cards. If a player draws the five "Exodia" pieces they will instantly win all of the battles against the team. However, if a card like "Speed Spell - Gold Sarcophagus" is used, and the current opponent loses before the card is added to the controller's hand, it will not be added, after the correct turn count.
- Team Unicorn: When the player duels against Andre, he has 2000 Life Points, "Thunder Unicorn" in Attack Position and 1 Set monster ("Playful Possum"). The player has "Speed Spell - Mystical Space Typhoon" and "Speed Spell - One for One" set face-down on his/her field. Both have 3 Speed Counters each. After defeating Andre, he/she continues to duel Jean.
- Team Catastrophe: When the player duels against Hermann, he has 4000 Life Points, "Dream Clown" in Attack Position, 1 Set card ("No Entry!!") and 1 Speed Counter. The player has "Scrap Goblin" in Attack Position, and "Speed Spell - Pot of Avarice" and "Speed Spell - Smashing Ground" set face-down on his/her field, and 3 Speed Counters. After defeating Hermann, he/she continues to duel Nicolas.
- Team Sherry: When the player duels against Elsworth, he has 6000 Life Points, "Driven Daredevil" in Attack Position and 2 Speed Counters. The player has "Bottomless Trap Hole", "Speed Spell - Angel Baton" and "Starlight Road" Set face-down on his/her field, and 7 Speed Counters. After defeating Elsworth, he/she continues to duel Sherry LeBlanc.
- Team Ragnarok: When the player duels against Dragan, he has 4000 Life Points, "Thor, Lord of the Aesir" in Attack Position and 2 Speed Counters. The player has "Speed Spell - The End of Storm", "Speed Spell - Mystical Space Typhoon", "Ultimate Offering" and "Prideful Roar" set face-down on his/her field, and 6 Speed Counters. After defeating Dragan, he/she continues to duel Brave, and eventually Harald.
- Team New World: When the player duels against Primo, he has 8000 Life Points and "Red Nova Dragon" equipped to "Meklord Emperor Wisel" in Attack Position. The player has "Sangan" in Defense Position and "Synchro Material" set face-down on his/her field. Both have 3 Speed Counters each. After defeating Primo, he/she continues to duel Lester, and eventually Jakob.

Locations in the game on the main map include:
Locations in the game on Satisfaction Town's map include:
Card programming errors
- Like Reverse of Arcadia, the numbers of Speed Counters required to activate "Speed Spell - Speed Storm" are incorrect. 3 or more Speed Counters are required to be able to activate the card, not 4 or more.
- "The Lady in Wight" grants immunity to applicable monsters on both sides of the field, despite stating "Zombie-Type monsters you control." Particularly noticeable when "Zombie World" is in play.
- The error is in the card text; the errata for "The Lady in Wight" released in Gold Series: Haunted Mine is correct.
- "Scrap Orthros" can miss the activation timing of its effect in this game. This should be impossible due to it's effect saying "if," not "when."
- "Speed Spell - Faustian Bargain" can target any of the opponent monsters, not just ones that were Special Summoned.
- "Unibird's" effect normally requires another monster and the card itself to be removed from play, but there is a bug that makes possible for the player to only remove Unibird from the game to bring a level 2 Synchro Monster like "Formula Synchron" from the Graveyard.
- Despite that you're given the "Lightning Warrior" at the very start of the game in your starter deck, for some unknown reason, the game might not able to read the card being in your trunk and you're unable to use it in deck editing outside the starter deck, unless you build your deck over your starter deck without removing it from the extra deck.
- However, using password on the "Lightning Warrior" seems to remove the problem.
- "Necrovalley" sometimes does not prevent access to your opponents graveyard. (EX: Cards are returned from the graveyard to the deck despite Necrovalley being on the field.)
- In Duels, Magical Android's" effect will not replenish your Life Points when the effect activates in the end-phase.
Card text errors
- "Blue-Eyes Toon Dragon", "Manga Ryu-Ran", "Toon Mermaid" and "Toon Summoned Skull" have a grammar error stating "If a face-up "Toon" monster is on your opponent's side of the field, your must select the "Toon" monster as an attack target.
- "Destiny HERO - Plasma" reads "your opponent's effect monster" whereas it should be "effect monsters.
- "Laval Judgment Lord" effect says Laval Lord Judgment.
- "Speed Spell - Dash Pilfer" reads "Gain control of '1face-up' Defense position monster"
- "Speed Spell - Speed Storm reads "Activate only when you have 4 or more Speed Counters. ". This is erroneous, as the card can be activated with only 3 Speed Counters.
- "Trishula, Dragon of the Ice Barrier" is spelled as "Trishula, Dragon of the Ice barrier".
- The effect of "Nimble Musasabi" reads ". . .You can also Special Summon up to 2 "Nimble Musasabi" to you opponent's side of the field. . ."
- "Lancer Dragonute" is spelled as "Rancer Dragonute".
- When starting a Duel, every now and then the music will not start until a later turn.
- Certain parts of the dialogue when playing as a female refer to the player as "him", "he", etc.
- When not abbreviated, the WRGP is spelled as "World Riding Gran Prix".
- When viewing a replay or recipe dueling, the Duel music is set to either the title screen music of this game or the person the player last dueled.
- Sometimes when a monster with an animated Summon sequence, such as "Blue-Eyes White Dragon" is Summoned, the card's name will be flickering.
- When viewing a replay of dueling 3-4 duelists (through a Dueling Simulator or WRGP), the player's life points are set to zero, but the duel goes on as usual.
- During the WRGP duels, when either player activates a card (e.g. "Magic Cylinder") and the player defeats the CPU at the same time. When the CPU switches, the cards remain on the field instead of going to the graveyard. The card effect's do not activate after the CPU switch.
- The CPU will not register that this card has already been activated so if it activates a card like "Mystical Space Typhoon" there is a chance it will destroy it instead of any actual face downs you may have.
- When using a card that changes control of a monster for only one turn in the WRGP it will stay on your side of the field for the rest of the continued duels if you defeat them on the same turn. This is because the End Phase of that turn will never occur in that situation.
- If a monster with piercing damage attacks a face-down monster and the damage would result in the opponent's loss, the "Final Attack" text will still be said when declaring the attack.
