Yusei successfully jumps off the trailer along with Aki before the trailer falls into the sea. His D-Wheel is passing the mysterious D-Wheeler. At this moment, [Speed World 2 - Field Spell: When you play a Magic card other than a Magic card with "Speed Spell" in its name, you receive 2000 points of damage. Both player's, during their Standby Phases, place 1 Speed Counter for themselves on this card. (A maximum of 12 for each player.) By removing a number of Speed Counter placed from your Speed World, you can activate one of following effects. 4: Inflict 800 Damage to your opponent for each "Speed Spell" Card in your hand. 7: Draw 1 card from your deck. 10: Destroy 1 card on the field] is activated in the mid air. His computer says, "Duel Mode!."
The mysterious D-Wheeler turns herself and follows Yusei behind. She hopes that they can duel now. Yusei asks what his opponent is talking about by dueling at this situation. The mysterious D-Wheeler says that operation of Yusei's D-Wheel has already been adjusted. As long as it is in a duel mode, he can't get off. If Yusei forces it to stop, the D-Wheel will explode. Aki and Yusei become very surprised. The mysterious D-Wheeler tells him that he has no choice as the battle has already begun.
Yusei asks whether there is no other way to settle down this. The mysterious D-Wheeler doesn't care what Yusei is saying and sets Speed World 2 on her D-Wheel. Once Speed World 2 is activated, many
digital signs indicating the duel location, "Duel Lane 528432-H", are lift up on both sides of the highway. The main transportation system identifies 3 courses and sets up a function, "Lane Selection!," to pick up and give authorization on a central lane of "Duel Lane 528432-H."

Once a riding duel course is determined, separate roads emerge from the sea. Yusei and the mysterious D-Wheelers are guided to follow these roads across the sea to the riding duel course authorized by the main transportation system. The computer system speaks to warn nearby vehicles and people that a riding duel is running, so they should proceed to the other ways.
Meanwhile, there is a mysterious man observing movement of Yusei and the mysterious D-Wheeler. Seeing both of them going across the sea, he puts on his helmet on and rides after them. Yusei and the mysterious D-Wheeler follow the course instruction to a riding duel driveway, where there is no public transportation. Aki looks at Yusei and gets worried about him. Yusei realizes that he has no choice but duels. He tells Aki to hang on tight and make sure that she won't fall off. Yusei and the mysterious D-Wheeler then declare a duel, "Riding Duel, Acceleration!." Aki thinks, "A riding duel at this close distance? I have been able to see what Yusei is seeing by the first time."

1st turn - The mysterious D-Wheeler
The mysterious D-Wheeler takes the first turn and draws a card. According to the effect of Speed
World 2, no Speed Counter increases in the first turn of the
game. Thus, the number of SPCs is 0 for both. She then summons [Spear Holder of the Holy Knight ~ Seikishi No Yarimochi - 2/800/400: By sending this card to the Cemetery, you can add 1 Equipment Magic card from your deck into your hand] to the field in defense position. Setting a face-down card, she ends her turn.

Yusei calls for his turn and draws a card. In
his standby phase, 1 Speed Counter is added to both sides following the effect of Speed World 2.
They result in 1 SPC (1+0) evenly. Yusei summons [Speed Warrior - 2/900/300: This can only be activated during the Battle Phase of the turn in which this card is successfully summoned. Double this card's original attack power until the end of the Battle Phase] to the field in attack position. According to its effect, its ATK can double in the turn it is summoned. The ATK of Speed Warrior thus becomes 1800 (900*2).
Yusei moves to battle phase, declaring the attack of Speed Warrior, "Speed Edge!," toward Spear Holder of the Holy Knight. The mysterious D-Wheeler opens face-down trap card [Floral Shield - Normal Trap: You can activate this card when your opponent's monster declares an attack. Negate that opposing monster's attack declaration and draw 1 card from your deck]. It allows her to negate the attack of Speed Warrior and draw 1 card. The strike of Speed Warrior is then blocked by floral storm forming into a shield. Setting 3 face-down cards, Yusei ends his turn. Aki sees that it is a well-evenly matched game in their first turns.

A turn moves to the mysterious D-Wheeler, and she draws a card. In
her standby phase, 1 Speed Counter is added to both sides following the effect of Speed World 2.
They result in 2 SPCs (1+1) evenly. The mysterious D-Wheeler summons [Swift Horse of the Floral Knight Force ~ Hanakishidan No Shunme - 3/400/800: When this card is summoned successfully, you can draw 1 card from your deck] to the field in attack position. When this card is summoned successfully, she can draw 1 card from her deck.
Next, The mysterious D-Wheeler plays [Speed Spell - Over Boost ~ Sp - Over Boost - Normal Spell: Increase your Speed Counters by 4 for this turn. Reduce your Speed Counters to 1 at the End Phase], which allows her SPCs to increase by 4 in this turn. However, they will be reduced to 1 at the end phase. By this play, her SPCs increase to 6 (2+4) and make her D-Wheel speed up. Aki is stunned by increasing of 4 SPCs. Yusei explains that this duelist is a D-Wheeler matching with speed.
The mysterious D-Wheeler next plays [Speed Spell - Speed Fusion ~ Sp - Speed Fusion - Normal Spell: You can only activate this card when your Speed Counters are 4 or higher. Send monsters listed on a Fusion Monster from your hand or field to the Cemetery to Special Summon 1 Fusion Monster from your Extra Deck. (This Summon is treated as Fusion Summon.)]. This card requires at least 4 SPCs to be played, and she currently maintains 6 SPCs to satisfy the condition. It works like Polymerization, allowing her to special summon a fusion monster.
The mysterious D-Wheeler fuses Spear Holder of the Holy Knight and Swift Horse of the Floral Knight Force to special summon [Centaurumina - 6/2200/1600: Once during your turn, you can negate the effect of an opponent's Trap card and re-set it back on the field] to the field in attack position. She quickly moves to battle phase, declaring the attack of Centaurumina toward Speed Warrior.

Yusei opens his face-down trap card [Scrap-Iron Scarecrow ~ Kuzutetsu No Kakashi - Normal Trap: Activate only when an opponent's monster declares an attack. Negate the attack, and Set this card face-down again instead of sending it to the Graveyard] to negate the attack of Centaurumina. The mysterious D-Wheeler activates the monster effect of Centaurumina at this moment. Once per turn, it can negate an activate of a trap card and set it faced-down. Centaurumina therefore steps on Scrap-Iron Scarecrow to negate its activation and set it back. Its attack, "Grace Illumine De!," toward Speed Warrior is resumed. Speed Warrior is finally destroyed, and Yusei's LP drops to 2700 (4000+900-2200).
The strike seems to impact Aki holding herself on Yusei's back. Yusei asks whether she is okay. Aki tells him that she is fine. More importantly, she is now amazed by a riding duel as she has never experienced it closely like this. Aki thinks, "How amazing! It is a normal duel but different from a psycho duel. What is this emotion echoing to my heart by this speed?." It appears that Aki is now impressed by and pulled into the the riding duel world.
Setting up a face-down card, the mysterious D-Wheeler ends her turn. At her end phase, her SPCs are reduced to 1 by the effect of Speed Spell - Over Boost. Her D-Wheel's speed also decreases along with her SPCs.

It's now Yusei's turn, and he draws a card. In
his standby phase, 1 Speed Counter is added to both sides following the effect of Speed World 2. Yusei ends up with 3 SPCs (2+1) while the mysterious D-Wheeler ends up with 2 SPCs (1+1). Yusei summons [Junk Synchron - 3/1300/500: When this card is successfully Normal Summoned, you can Special Summon 1 Level 2 or lower monster in your Graveyard in face-up defense mode. Any effects of an Effect Monster Special Summoned by this effect are negated] to the field in attack position.
With the monster effect of Junk Synchron, a monster with level 2 or less can be special summoned from the graveyard. Yusei therefore calls Speed Warrior back to the field in attack position. He tunes Junk Synchron into Speed Warrior. "Clustering stars will call upon a new power! Become the path its light shines upon!," Yusei says and synchro summons [Junk Warrior - 5/2300/1300: When this card is Synchro Summoned, this card's attack power is increased by the total of the attack power of all Level 2 or lower monsters face-up on your side of the field] to the field in attack
position.

Aki is very amazed by a synchro summon done through a riding duel. Yusei declares the attack of Junk Warrior, "Scrap Fist!," toward Centaurumina. The mysterious D-Wheeler opens her face-down trap card [Fleur Guard - Normal Trap: Select 1 monster on your side of the field to activate this card. The selected monster cannot be destroyed by battle during this turn]. According to its effect, her monster can't be destroyed by battle in this turn. Yusei calls that battle damage is still calculated, so her LP drops to 3900 (4000+2200-2300). Setting up a face-down card, he ends his turn.
Aki thinks, "How amazing! Both are exchanging their crush drastically as if they are partners fighting together many times." At this point, Yusei is curious who this D-Wheeler is. He feels that this D-Wheeler's manner is different from being a part of the group trying to kidnap him. It's because this D-Wheeler rather is enjoying a duel. Aki looks stunned by Yusei's words.

A turn moves to the mysterious D-Wheeler, and she draws a card. In
her standby phase, 1 Speed Counter is added to both sides following the effect of Speed World 2. She ends up with 3 SPCs (2+1) while Yusei ends up with 3 SPCs (3+1) respectively. She then summons a tuner monster [Fleur Synchron - 2/400/200: If this card is used for a Synchro Monster's Synchro Summoning and sent to the Cemetery, you can Special Summon 1 level four or lower Normal Monster in your hand to your side of the field] to the field in attack position.
Yusei is stunned by seeing a tuner monster. Aki warns him that it's coming. Yusei understands well what she means. The opponent's ace monster by a synchro summon is about to appear. The mysterious D-Wheeler tunes Fleur Synchron into Centaurumina. "Body spawned from the speed of light, the time for revolution has come. May you bring me victory! Synchro Summon! Shine, Fleur-de-Chevalier!," she says and synchro summons [Fleur de Chevalier - 8/2700/2300: Once during you or your opponent's turn, you can negate the activation of an opponent's Magic or Trap card and destroy it] to the field in attack position.

According to the monster effect of Fleur Synchron, when it is used in a synchro summon, a monster with level 4 or less can be special summoned from hand. The mysterious D-Wheeler therefore calls [Apprentice Knight ~ Minarai Kishi - 2/1000/1000] from her hand to the field in attack position. Yusei knows that he has Scrap-Iron Scarecrow, and his opponent should be aware of it well. He doesn't think that she is going to attack without a plan. Yusei smiles and feels interested. He would like to know how his opponent is going to respond. At this moment, Aki sees that even Yusei is enjoying a duel.
As Yusei has expected, the mysterious D-Wheeler declares the attack of Fleur de Chevalier, "Fleur De Mirage!," toward Junk Warrior. Yusei opens his face-down trap card Scrap-Iron Scarecrow to negate the attack. It's what the mysterious D-Wheeler has waited. She activates the monster effect of Fleur de Chevalier. Once per turn, it can negate the activation of the opponent's spell/trap cards and destroy it. Thus, Scrap-Iron Scarecrow is destroyed as Aki and Yusei have expected that something had to be done with it.
Without Scrap-Iron Scarecrow, Junk Warrior is destroyed, and Yusei's LP drops to 2300 (2700+2300-2700). Yusei admires that his opponent did it well. Anyway, he has already been aware of her monster's special effect. In response to it, he opens his face-down trap card [Afterglow of Miracle ~ Kiseki No Zanshou - Normal Trap: Special Summon 1 monster in your Cemetery destroyed during this turn to your side of the field], which can special summon 1 monster destroyed in this turn from the cemetery. Yusei thus calls back Junk Warrior to the field in attack position.

The mysterious D-Wheeler sets up 2 face-down cards and ends her turn. She then calls that Yusei Fudo did it well as expected. Both Aki and Yusei are stunned by what she means. The mysterious D-Wheeler stops riding and turns back to Yusei. It makes it clear to Yusei as he can read what's going on. Yusei speeds down his D-Wheel and prepares to stop. Aki asks why he is doing it. As he forces it to stop, his D-Wheel may explode. Yusei finally stops his D-Wheel, and Aki is surprised by that there is no explosion.
Yusei knows that it's just a bluff. He asks directly who the mysterious D-Wheeler is and why she has to do such a silly thing. The mysterious D-Wheeler takes of her helmet to reveal her face and long-bonze hair. She introduces herself as [Sherry Leblanc] and explains that she is doing this to test Yusei's true skill. Aki is amazed by seeing a female D-Wheeler. Sherry apologizes Yusei for bluffing him. She says that she has come to take him as she doesn't plan to let him go with the other teams.
