7. Yu-Gi-Oh ARC-V A New Story of Pendulum (Xyz Arc)

Chapter 13 Thunder Spark Riding Duel

The steel door towered before them, humming faintly with stored power. As Yuni reached out to touch it, a violent surge erupted — blue electricity webbing across the metal like living veins. The air cracked with static, forcing everyone to stumble back.

"What the... there's electricity on the door?" Yuni exclaimed, shaking her hand.

Reisho grimaced. "This is really bad. The Commander sure doesn't want us getting inside."

"The Commander doesn't know a thing about this."

The unfamiliar voice cut through the electrical buzz. All eyes turned toward the corridor's far end, where the echo of a motor grew louder and louder. A bright blue streak came into view — a D-Wheel, sleek and modified, leaving arcs of lightning in its trail.

The rider came to a stop before them. His black suit gleamed with yellow circuitry patterns that pulsed like a heartbeat. He flipped up his visor, revealing sharp amber eyes and a calm, confident smirk.

Katrina stepped forward. "Who are you?"

"I live in the world of speed," he said evenly. "The name's Thunder Spark. I'm here to stop you from taking another step." He drew a glowing card from his deck — a golden number shining in its center. "And I think this is what you're after."

Everyone's breath caught.

"Numbers!" Katrina gasped. "How did you get that?!"

Astral floated beside Yuni, his tone serious. "You're a Number Spirit... just like Wrath or Garruk."

Thunder Spark's eyes narrowed with faint amusement. "Correct. I am the will of Number 91 — Thunder Spark Dragon. Anyone who wants this card must prove they can handle the storm."

Yuni met his gaze and climbed onto her D-Wheel, visor lowering. "Then I'll be your opponent."

Sawatari blinked. "So they're dueling for a Number Card again?"

Reisho exhaled through his nose. "Seems so. We'll wait — the barrier won't drop until one of them wins."

Thunder Spark revved his D-Wheel, the engine's roar blending with bursts of static. "Hope you can handle lightning speed, girl."

"Try me," Yuni shot back, her D-Wheel humming to life.

Rio tilted her head. "Are they seriously riding and dueling at the same time?"

"This is the Synchro Dimension's dueling style," Reisho explained. "Riding Duels."

Both duelists rolled to the starting line. Their Duel Disks extended with a mechanical click, and a soft electronic tone echoed — the activation signal. At once, the floor beneath them glowed.

From the light rose a circuit of blue platforms, each one forming in midair with a metallic shimmer. They stretched outward in a wide loop, suspended above the ground and stabilized by arcs of energy linking them together. The space between them crackled faintly, a dimensional field taking shape.

Thunder Spark's visor lowered again. "Let's ride."

Engines roared in unison. The two D-Wheels shot forward, light streaming beneath their tires. The Crossover Field stabilized around them, casting blue light across the hall.

"Duel!" they shouted together. (Yuni: 4000)(Thunder Spark: 4000)

Thunder Spark leaned into the curve, the roar of his D-Wheel cutting through the air like thunder itself. Sparks trailed behind his wheels as his eyes gleamed beneath the visor. "Here I go! I summon OToThunder!" (ATK:1300/DEF:600/Level 4)
