A K, Fuma, EJ & Nicholas One-Shot (Rivalry & Chaos Trope)

*****

K should have known better.

He should have known that letting Nicholas and EJ team up against him and Fuma was a mistake.

He should have known that any friendly competition between the four of them would turn into absolute chaos.

And yet, here he was—shoulders tense, grip tight on the controller, staring at the screen like his life depended on it.

Because it did.

Sort of.

If he and Fuma lost this match, Nicholas and EJ would never shut up about it.

And K refused to let that happen.

Nicholas smirked, stretching lazily. "You're looking a little stressed, K."

EJ, sitting beside him, nodded thoughtfully. "You're usually so composed. What happened?"

K exhaled slowly. "I'm fine."

Fuma grinned. "We're fine."

Nicholas scoffed. "Not for long."

K gritted his teeth.

This was just a game.

It should have been just a game.

But somewhere between the first round and now, it had escalated into a full-blown war.

And K, who had once prided himself on not getting dragged into their nonsense, was now fully involved.

The match was down to the wire.

Fuma's fingers flew over the buttons, eyes locked onto the screen with unshakable focus.

K, next to him, was calculating every move, planning every counterattack.

Meanwhile, on the other side—

Nicholas was laughing like a maniac, aggressively mashing buttons.

EJ, completely unreadable, sat beside him, dangerously calm.

"We've got them," Nicholas declared. "K looks like he's about to combust."

"I do not," K shot back, though, admittedly, his jaw was tight.

Fuma snickered. "A little bit."

K ignored him.

They were seconds away from victory.

One last move—one final strike—

And then—

EJ sniped them from the corner of the map.

Game over.

Silence.

Nicholas leaned back with a satisfied sigh. "Beautiful. Truly, a work of art."

Fuma dropped his controller. "No. No way."

K stared at the screen in disbelief.

EJ, as always, looked completely unbothered. "Huh. That was easier than I expected."

Nicholas cackled. "I told you we were gonna win."

K exhaled through his nose. "This is ridiculous."

Nicholas grinned. "What's ridiculous is how bad you lost."

Fuma crossed his arms. "Alright, rematch."

EJ blinked. "Again?"

K nodded firmly. "Absolutely."

Nicholas stretched, smirking. "Alright, but when we win again, you're buying us dinner."

K narrowed his eyes. "You're getting nothing."

Nicholas just winked. "That's what you think."

And with that, the battle started all over again.

*****

K and Fuma had one goal.

Win.

Wipe those smug grins off Nicholas and EJ's faces.

Restore their honor.

But most importantly—shut Nicholas up.

Because if K had to hear one more cocky remark from him, he might actually lose his mind.

The second match started fast.

No warm-up, no hesitation—just immediate chaos.

K and Fuma moved like a well-oiled machine—years of teamwork making their coordination flawless.

Nicholas, however—Nicholas was the definition of chaos.

Mashing buttons. Trash-talking nonstop. Laughing like he had already won.

And EJ?

EJ was terrifying.

Completely silent. Completely focused.

And worst of all—completely unreadable.

Fuma gritted his teeth. "K, we need a strategy."

K exhaled sharply. "Survive."

"Oh, this is too easy," Nicholas sighed dramatically.

K's eye twitched.

"We should've given them a handicap," Nicholas continued. "Maybe played with one hand? Or blindfolded?"

K gripped his controller tighter.

Fuma scowled. "Nicholas, if you don't shut up—"

"What? You'll lose faster?" Nicholas grinned.

EJ, without looking away from the screen, muttered, "Focus, Nicholas."

Nicholas waved a hand. "Relax, we have this in the bag."

K scoffed. "Not this time."

And then—

K went for the kill.

In a flash, K's character launched a perfectly executed counterattack.

Nicholas yelped. "Wait, what—?!"

EJ moved quickly, trying to recover—but it was too late.

Fuma took the opening, finishing the job.

Game over.

Victory: K & Fuma.

K let out a breath of relief.

Fuma threw his hands in the air. "YES!"

Nicholas stared at the screen in disbelief.

EJ blinked. "Huh."

K smirked. "Not so easy now, is it?"

Nicholas scoffed, crossing his arms. "Okay, okay. You got lucky."

Fuma grinned. "No, we got skilled."

Nicholas rolled his eyes. "Fine. Whatever. Best two out of three."

K raised an eyebrow. "Oh? You want to lose again?"

Nicholas grinned. "Like that's gonna happen."

And just like that, the battle continued.

Because when it came to K, Fuma, EJ, and Nicholas...

There was no such thing as "just one game".

*****

It had all come down to this.

One final match.

One game to settle everything.

Winner takes all.

Loser?

Endless humiliation.

Nicholas cracked his knuckles. "Alright, ladies and gentlemen—"

"There are no ladies here," K muttered.

Nicholas ignored him. "—this is the ultimate showdown. The final battle. The war to end all wars."

Fuma rolled his eyes. "Can you stop monologuing and just play?"

Nicholas smirked. "I'm setting the atmosphere, Fuma."

EJ, still completely calm, adjusted his headset. "Let's just win."

K, focused and ready, nodded once. "Agreed."

And then—

The game began.

This time, everyone played dirty.

No more holding back. No more mercy.

Just pure, unforgiving competition.

K was ruthless. Calculated, sharp, attacking at the perfect moments.

Fuma was unpredictable. Quick, aggressive, taking risks that somehow always worked.

EJ was unreadable. Effortless. Precise. Deadly.

And Nicholas?

Nicholas was Nicholas.

A complete menace.

Yelling, laughing, button-mashing like his life depended on it.

"STOP GOING FOR ME!" Fuma yelled as Nicholas relentlessly targeted him.

Nicholas cackled. "IT'S CALLED STRATEGY, BABY."

K wasn't safe either.

EJ had singled him out, focusing on countering his every move.

"You're really annoying," K muttered, dodging another perfect attack.

EJ simply smirked. "I know."

It was too close.

Both teams were one hit away from victory.

One mistake—one second too slow—and it would be over.

Nicholas narrowed his eyes. "Alright, EJ. Let's finish them."

K and Fuma exchanged a glance.

This was it.

The deciding moment.

The ultimate move.

And then—

Fuma betrayed K.

K stared in horror as Fuma—his teammate, his ally, the one person he thought he could trust—suddenly turned on him.

Fuma eliminated K.

Their team lost.

Nicholas threw his hands up in victory. "HAHA! YES! I KNEW IT! I AM A LEGEND."

EJ gave a satisfied nod. "Nice work."

K, still processing, slowly turned to Fuma.

"...Why."

Fuma shrugged, grinning. "Seemed fun."

K closed his eyes and took a deep breath.

Nicholas burst out laughing. "Oh my God, Fuma. That was COLD."

Fuma smirked. "What can I say? I like surprises."

K exhaled slowly. "You're all terrible."

Nicholas slung an arm around him. "Come on, don't be salty. Just admit it—we're the best."

K shoved him off. "I'm never playing with you again."

Nicholas grinned. "See you next game."

K groaned.

Fuma laughed.

EJ just sipped his drink like nothing happened.

And thus, the greatest rivalry of all time... was far from over.
