Who Let Him Play Yugioh? (Re-Upload)

”By the way…Kira, why are you suddenly interested in other worlds?”

Kaiba’s brother, Mokuba, was walking with Kira down a long metallic corridor, deep inside a top-secret KaibaCorp lab. As they walked, Mokuba looked curiously at Kira.

”Suddenly? Oh…”

Kira repeated the word, then realized.

”You mean Kaiba?”

It seemed that after Atem disappeared, President Kaiba had become obsessed with interdimensional technology. Within a year, he’d developed devices capable of dimensional travel—the level of black-tech was terrifying.

”Yeah, my brother’s been heavily developing dimensional tech these years. I’m not super interested, but I’ve picked up some theory recently.”

Mokuba tilted his head, thinking.

”Let’s see…how did they put it? Oh, right.”

He shook his head, ”Although we’ve achieved dimensional travel, and can even enter some spirit dimensions, some of our scholars pointed out that the spirit world, though it seems to be another dimension, is really just an extension of our reality.

The world we live in, what humans see, is just the tip of the iceberg. They compared it to cards.”

”Cards?”

”Yeah. The front and back of a card,” Mokuba said. ”If you use a card as a metaphor, our human world is the front, the spirit world is the back.

But it’s still the same card, the same dimension.”

Kira seemed to understand. ”And so-called parallel worlds would be other cards. Is that right?”

”You catch on quick.”

Mokuba smiled, nodding.

”Yes, that’s about it. Our research then found that, in theory, travel between different planes is possible.

In fact, deeper research suggested that dimensional travel may have already happened in our world—just that no one realized before.”

Kira frowned. ”Someone from here went to another dimension?”

”No, they suspect someone from another world came here,” Mokuba said. ”But back then we didn’t know about parallel universes, so we never noticed.

That’s why we later designed this—”

As he spoke, Mokuba led Kira to the deepest part of the lab. The metal doors automatically opened, revealing a massive device.

At the center of the hall was Earth.

A projection of Earth, its semi-transparent blue glow hovering in the air with a sacred aura, as if a membrane of energy shrouded its surface.

”This is a radar for detecting any planar anomalies worldwide,” Mokuba said. ”It’s designed to prevent any invasion attempts into this dimension!”

Kira gazed at the floating blue sphere, clicking his tongue in awe.

”Amazing. KaibaCorp really has stuff like this…”

Mokuba walked up to the sphere, smiling. ”Well, it’s just a prototype for now—a barely functional global coverage system.

But how effective it is remains to be seen. You’d only know if there was a real invasion.

But it’s not like otherworlders just pop up like cabbages, you know…”

Kira hesitated for a second, pointing at a red dot on the globe. ”Uh…so what does that red dot mean? Don’t tell me there’s really an interdimensional incursion?”

Mokuba laughed, ”How could that be?”

He followed Kira’s gaze to the red dot on the floating Earth—then froze.

Almost at the same time—

A piercing alarm sounded, and a voice boomed over the loudspeaker: ”Alert! Dimensional radar has detected an anomaly! Suspected dimensional incursion!”

Kira: ”…”

Mokuba: ”…”

Guess the cabbage really did pop up.

….

At this moment—

A pitch-black spatial rift was slowly closing, violently torn space struggling to return to normal.

A blond man straddled a white floating vehicle, hovering high in the air. He wore a mask, hiding his true face, but his eyes behind the mask looked strange.

”No, this isn’t right…”

He glanced at a device on his wrist, fiddling with it, and soon a floating screen appeared.

”No, this isn’t right…”

His frown deepened.

”This chaotic history…no, it’s all wrong. This isn’t how it’s supposed to be.”

As he muttered to himself, a voice suddenly sounded behind him: ”What’s wrong? Share it with me?”

The man started, turning to see Kira floating nearby, staring right back.

”You?”

The man compared Kira to the projection on his wrist screen, then frowned in confusion: ”Fujiki Kira…the Duel King?”

He shook his head repeatedly.

”No, that’s not right. You shouldn’t exist—everything’s out of order…”

Kira frowned slightly. This guy didn’t seem all there…

Are all otherworlders like this?

The man muttered, ”Has history already been corrected? No, it shouldn’t be. This level of interference shouldn’t be enough to shake history…”

He paused, then looked up. Sharp light shot from his eyes beneath the mask.

”Only one way to find out.”

Lifting his arm, his activated duel disk was already prepared.

He didn’t know why, but it looked like they’d have to duel after all.

Kira wasn’t surprised. He’d come prepared.

Mokuba’s voice came through the headset, ”Careful, Kira. No telling how duels with outsiders differ from ours.

I’ve already notified my brother—he’s on his way.”

”For that, I’m sorry to President Kaiba,” Kira grinned. ”He probably won’t make it in time—this’ll be over quickly.”

”Duel!” x2

[Kira, LP 4000]

[Outsider, LP 4000]

”I’ll go first. Draw.”

Kira took the first turn. After drawing, he raised an eyebrow and smiled strangely. He drew two cards, placing one in the monster zone face-down, and one in the back row.

”Set one monster in face-down defense, set one back row card, end turn.”

”My turn. Draw.”

The outsider drew, and a slot opened on the side of his duel disk.

”Field Spell—

—Malefic World!”
