The Infinity Castle twisted and turned, shifting like a living nightmare. Inside one of its massive halls, a man stood with all the confidence of a rockstar.
Tengen Uzui, the God of Festivals, flicked his golden headband, adjusted his glorious muscles, and spun his dual Nichirin Cleavers like he was warming up for a fireworks show.
On the other side, Upper Rank Six—Gyokko emerged from a giant flesh vase, slithering out like a cursed sushi chef who had been fired for excessive tentacles.
"Oh my, oh my! Look at this flashy human!" Gyokko giggled, his voice dripping with arrogance. "Such terrible taste. That headband? Those gaudy swords? Your aesthetic is downright offensive!"
Tengen grinned, tossing a kunai in the air.
"I'll have you know, you deformed goldfish, I'm the flashiest man alive."
Gyokko's eyes twitched. "HOW DARE YOU COMPARE ME TO A COMMON FISH?!"
He slammed his palms together, and several grotesque fish demonsflopped out of his vases, their teeth sharper than Tengen's fashion sense.
"It's over, flamboyant fool! My art shall devour you!"
Tengen cracked his knuckles.
"Pfft, if this is art, then I'd rather be blind."
Gyokko snapped his fingers, and the fish demons lunged at Tengen, their mouths foaming with acidic water.
"Go forth, my minions! Make this unworthy brute part of my masterpiece!"
Tengen dodged effortlessly, flipping over one fish demon while twirling his swords like a drum major.
"Sound Breathing: First Form—ROAR!"
He slammed his cleavers into the ground, causing a massive explosion that sent the fish demons flying like a seafood buffet gone wrong.
One fish demon crashed into a wall and burst into sashimi.
Another was sent spiraling into Gyokko's own vase, getting stuck headfirst like a struggling tuna.
"MY BEAUTIFUL FISH! YOU MONSTER!" Gyokko wailed.
Tengen flashed his perfect teeth.
"You started it, calamari boy."
Gyokko hissed, summoning more vases that began shooting high-pressure water blades.
"Water Blades? How original," Tengen mocked, dodging the attacks with acrobatic flips that made even gymnasts jealous.
With a casual smirk, Tengen flicked a handful of explosive beads towards the vases.
"Boom time."
BOOM!
The vases detonated instantly, showering the battlefield in porcelain shards and dead fish parts.
Gyokko screamed in frustration.
"You... YOU DARE DESTROY MY MASTERPIECES?!"
Tengen yawned dramatically.
"Oh, my bad. I thought we were here to FIGHT, not admire your questionable taste in decor."
Gyokko shook with rage, his veins bulging with artistic fury.
"Enough games! Witness true beauty!"
His entire body began to molt, shedding his disgusting humanoid form to reveal his final evolution—Molted Gyokko.
Gone were his wimpy arms. Now, his scaled body was harder than diamond. His claws gleamed with poison.
"BEHOLD! My TRUE form!"
Tengen tilted his head.
"Huh. I didn't think it was possible, but you somehow got even uglier."
Gyokko's eye twitched so hard, he nearly dislocated his own face.
"DIE!"
He lunged forward, his claws swiping at Tengen with lightning speed.
Tengen barely dodged, feeling the wind pressure from the strike.
"Oh? Faster now? That's kinda flashy."
Gyokko grinned, spinning mid-air.
"Everything you touch… BECOMES A FISH!"
The ground around Tengen suddenly transformed into a sea of writhing fish flesh, squirming and lunging for him.
Tengen grimaced.
"Ew. Nope. Nope nope nope."
He jumped onto a wall, avoiding the slimy transformation zone.
"Alright, sushi man, you've had your fun. Now it's my turn!"
Tengen took a deep breath, his muscles flexing and manifested his Demon Slayer Mark.
"Time to go all out."
Gyokko snickered.
"You're already losing! What can you possibly—"
Tengen vanished.
Gyokko's smug smile disappeared.
Then—
SLASH!
A massive explosion erupted right in front of Gyokko, the force so strong it cracked the walls of the Infinity Castle.
"Sound Breathing: Fifth Form—STRING PERFORMANCE!"
Tengen's swords spun in a deadly whirlwind, slicing through the fish-infested battlefield like a cyclone of destruction.
Gyokko screeched, his diamond-hard scales cracking under the overwhelming assault.
"IMPOSSIBLE!"
Tengen appeared above him, spinning mid-air like a dancer.
"This is my grand finale, squid boy."
"SOUND BREATHING: CONSTANT RESOUNDING SLASHES!"
His swords flashed, each slash detonating in rapid succession, creating a symphony of explosions.
Gyokko screamed, his body being ripped apart by relentless attacks.
Finally, Tengen landed, grinning confidently.
Gyokko wobbled, his head barely attached.
"H-HOW? HOW DID YOU—"
Tengen winked.
"Sorry, no critiques allowed. This masterpiece is complete."
SLASH!
With one final spin, Tengen decapitated Gyokko, his head flying into one of his own vases.
His body twitched, then collapsed into dust.
Tengen took a deep breath, wiping his sword clean.
"Too easy."
He turned to the Infinity Castle ceiling, raising a fist.
"Hey, Raja! You watching? Tell Muzan to send someone who doesn't suck next time!"
From somewhere in the castle, Raja facepalmed.
"That's gonna make him send someone worse, idiot."
Tengen grinned, twirling his swords.
"Then it'll be even flashier!"
