One Piece: Starting with Sharingan, First Mate Uchiha

Inside the bullfighting arena.

Amidst deafening cheers, Luffy and the bull, like perfectly in sync partners, galloped joyfully across the water arena, one on horseback and the other on foot.

Luffy burst into laughter, turning this bloody and brutal free-for-all into a bullfighting knight show.

However, in this hellish arena where countless outlaws of the new world gathered, this carefree joy did not last long.

"The arena is not for playing around, you dwarf!"

It was accompanied by a deafening, violent roar, like muffled thunder.

A massive, suffocating black shadow suddenly descended, completely blocking the sunlight from Luffy's head.

That was Hajrudin, a giant warrior from the legendary land of giants, Elbaf!

His massive, mountain-like body stood like an unshakeable demon god, blocking the bull's charge.

Halding gripped the enormous, incredibly heavy weapon tightly with both hands, veins bulging on his thick arms, and slammed it down on the man and the bull below!

"Moo-shi!"

With a piercing and painful scream, the already enormous bull looked like a toy in front of the real giant.

Haildin unleashed his terrifying, monstrous strength without reservation, smashing the bull and the solid stone arena beneath its feet to pieces.

The poor bull coughed up a mouthful of blood and collapsed heavily into the swirling dust of the ruins.

"Moo-shi!" Luffy exclaimed in mid-air.

With his exceptional fighting instincts, he leaped off the bull's back a second before being hit.

Like a light feather, it landed gently on a broken, warped stone slab.

A gentle breeze blew by, and Luffy kept his head down.

Seeing Luffy alone, the group of gladiators around him, whose eyes were already bloodshot, thought they had a chance to take advantage of him.

They immediately brandished their swords and rushed in from all directions, attempting to seize any remaining loot.

The giant Hajrudin in front of him let out a contemptuous snort, roared, and raised his fist again, powerful enough to shatter city walls, ready to crush the leaping "insect" completely.

The next second, Luffy's body surface instantly turned bright red.

His blood flowed rapidly like boiling water, and streams of hot white steam rose from his pores.

"You bastard..."

Luffy slowly raised his head, his clear eyes now filled with icy rage:

"They actually beat up my new friend like this!"

He clenched his teeth and stretched his right fist backward to its maximum extent.

Immediately afterwards, a high concentration of Armament Haki instantly covered his rapidly expanding right fist like flowing water.

"Rubber, rubber—"

Luffy's gaze locked onto the invincible giant before him, and he let out a roar that resounded through the heavens:

"Grizzly Gun!!!"

"BOOM—!!!"

A massive, jet-black fist, brimming with fury, slammed head-on into the giant Hajrudin's broad chin, like a heavy meteorite launched from its barrel!

Amidst the horrified gazes of tens of thousands of spectators, as if they had seen a ghost, the once majestic giant warrior's eyes rolled back after being struck by this punch.

He didn't even have time to let out a scream before his massive body, as huge as a toppled mountain, lost all consciousness and collapsed backward with a crash.

The massive body of Halding falling generated a terrifying shockwave, which swept away the swordsmen who were trying to sneak up on him, as well as the remaining strongmen in Zone C, like leaves being swept away!

Water splashed everywhere, and screams echoed.

The previously fierce and chaotic battle in Zone C was instantly decided by this one punch!

Gaz, the commentator sitting on the high platform, excitedly grabbed the microphone:

"The game is over!"

"The ultimate winner of Zone C!"

"The Minotaur Killer who can annihilate a giant in a single blow! He is Gladiator Lu..."

However, before Gaz could finish speaking...

Following Luffy's devastating blow that shocked the entire audience.

The conspicuous bull-head mask he was wearing, which already had some cracks, finally gave way under the terrifying shockwave and made a crisp "crack" sound.

Luffy's iconic straw hat and his expressive face were displayed without any concealment to the entire audience.

"Gladiator... Straw Hat Luffy?!"

The announcer, Gaz, whose voice was originally high-pitched, suddenly stammered.

He rubbed his eyes hard, staring incredulously at the close-up shot on the big screen.

Immediately after a brief silence, the entire bullfighting arena erupted in gasps and screams!

Everyone recognized that face!

That was the supernova who shone brightly in the Marineford War two years ago and turned the whole world upside down!

Luffy, the Straw Hat Boy who has defeated powerful enemies one after another and is now famous throughout the New World, giving countless Marines a headache!

"Oh my god! I'm not seeing things, am I?! That's Straw Hat Luffy!"

"A pirate with a bounty of one billion! What's he doing here?!"

"Run! This guy's a complete madman!"

The once orderly stands instantly descended into complete uproar and uncontrollable chaos.

Some audience members screamed and tried to run away, while others waved their fists and shouted wildly.

Hearing the overwhelming shouts around him, Luffy quickly reached up and pressed his straw hat to his head, sweating profusely as he loudly retorted in an attempt to cover up his embarrassment:

"Hey! You've mistaken me for someone else! I'm Lucy! Not some straw hat!"

But such a weak and unconvincing explanation is of no use at this moment.

The naval spies in the stands have already started pulling out Den Den Mushi (snail phone) to call for backup.

Just as Luffy was seeing the situation spiraling out of control and was preparing to slip away in the chaos,

A man with a green rooster-like hairstyle, a fierce-looking face, and a nose ring suddenly pounced on Luffy's feet like a vicious dog that had smelled meat!

This man is none other than the rising star known for his cruelty and madness, "The Cannibal" Bartolomeo!

However, to the astonishment of everyone present, whose jaws dropped to the floor.

This notorious underworld boss, who inspired fear in the outside world, was now completely devoid of any ferocity.

He lay on the ground, crying so hard that snot and tears covered his face.

Bartolomeo, his hands trembling, pulled out a bounty poster with Luffy's bright smile printed on it from his pocket with utmost reverence.

Then she clung tightly to Luffy's leg, letting out a pig-like scream of excitement:

"Luffy... Luffy-senpai!"

"Waaaaah! I finally saw one alive with my own eyes!"

"I'm your biggest fan! Please sign my autograph! Sign it on my chest!!!"

Looking at the strange guy in front of him, who was so excited that his whole body was convulsing and even had huge snot bubbles coming out of his nose, Luffy felt very troubled.

He was so preoccupied with the fact that his identity had been exposed that he had no desire to get entangled with these strange fans.

"Oh no! I'm busy right now! Let go of me!"

Luffy shouted and used his legs to propel himself high into the air with a "whoosh".

He traced an arc in mid-air and crashed into the solid stone wall at the edge of the arena with a loud bang.

Covering a trail of dust, they fled desperately into the intricate passageways of the arena, leaving Bartolomeo standing there, holding the bounty poster and weeping bitterly.

……

In the dimly lit underground world.

Luffy raced through the maze-like underground corridors of the arena.

"Honestly, that green-haired, combed-rooster-like man is so persistent!"

Luffy quickened his pace while complaining.

Just as he ran past a dimly lit corner.

A long, slender arm holding a steel water pipe suddenly and without warning stretched out from the shadow of the stone door beside them.

That hand grabbed Luffy by the back of his collar with perfect precision.

Even Luffy, who possesses extremely strong Observation Haki, was completely unprepared for this hostile force while running at high speed and being chased.

He felt his body lighten, and was pulled directly into a secret room by this familiar and powerful force.

With a "bang," the stone door slammed shut behind them.

Luffy quickly steadied himself in the darkness. His keen combat instincts made him clench his fists instantly, a hint of domineering aura emanating from them, just as he was about to throw a punch.

However, before he could throw a punch, a voice carrying a hint of indulgent laughter quietly rang out in the secluded room:

"Where are you going, Luffy, rushing around like that in such a hurry?"

Upon hearing that voice, Luffy's fist, brimming with Haki, abruptly stopped in mid-air.

His clear eyes widened instantly, and his pupils trembled violently.

Luffy suddenly raised his head and finally saw the person in front of him clearly.

He was a tall and upright young man.

He wore a top black hat with goggles on top, and his short blond hair was still noticeable in the dim light.

Looking at that face that had appeared countless times in his dreams, Luffy's tears instantly overflowed.

He opened his mouth wide and let out a cheer that was tinged with tears:

"Sabo!!!"

Luffy pounced on him and gave the blond youth a big hug.

Feeling Luffy's real body temperature in his arms, Sabo reached out and pressed down his top hat, a gentle and bright smile on his lips, and patted Luffy's back lightly.

After a brief moment of excitement, Luffy released his grip and grinned broadly:

"Sabo! It's been at least two years since we last saw each other!"

"The last time we met was... oh well, never mind!"

"How did you end up in Dressrosa all of a sudden?!"

Seeing Luffy's usual simple-mindedness, Sabo smiled and explained.

He stated that he had received a covert mission to investigate the country's clandestine arms smuggling operations around the world.

He really didn't expect to run into the Straw Hat Pirates here by such a coincidence.

The two brothers, separated for a long time, reunited and briefly reminisced in the darkness.

Suddenly, a flash of inspiration struck Luffy.

He recalled the terrifying, earth-shaking noise he had felt during the fight on the arena.

He asked Sabo with great curiosity what major event had happened outside.

Sabo was slightly taken aback when he heard the question.

Then, a strange smile appeared on his lips:

"That earth-shattering commotion just now wasn't made by anyone else, it was your first mate."

"He just got into a head-on fight with a top-tier fighter sent by the Yonko 'Big Mom' Pirates in the Dressrosa plaza."

Upon hearing the words "Four Emperors," Luffy was taken aback for a moment.

Then, he hurriedly stood up:

"What?! A Yonko's man! Victor is in danger!"

"No, I have to leave now. I'm going to help him beat those guys up!"

With that, Luffy turned around and was about to push open the heavy stone door.

However, Sabo smiled and reached out, firmly pressing down on Luffy's shoulder.

Under Luffy's puzzled gaze, Sabo shook his head slightly, his smile deepening.

"No need to go, Luffy."

Sabo's gaze seemed to pierce through the thick stone wall as he murmured:

"The battle over there... is over."
