One Piece: Starting with Sharingan, First Mate Uchiha

Above the dome of Onigashima, a fierce wind swept through the crisscrossing cracks, stirring up dust and pebbles, and making Luffy's straw hat flutter loudly.

Kaido, carrying the Eight Precepts, glanced past Luffy and looked at the purple war god in the distance who was lifting Onigashima.

"That red-eyed brat chose to protect the people below."

Kaido withdrew his gaze, a cruel smile appearing on his face.

"Now, no one can block my spiked club for you."

Luffy raised his hand to hold down his straw hat and grinned.

"It wasn't necessary in the first place."

"Viktor will do what he has to do, and I will do what I have to do."

He clenched his fists, and black and red Conqueror's Lightning rapidly coiled along his arms.

"I'll send you flying!"

Kaido was taken aback for a moment, then threw his head back and burst into laughter. The laughter pierced through the dark clouds, causing rubble to fall from the broken dome beneath his feet.

"Uro ro ro ro!"

"Then let me see just how capable you are as captain without a first mate standing by!"

The Eight Precepts were slowly raised.

The next instant, both figures vanished from their original positions.

boom--!

The fist, wreathed in Conqueror's Haki, clashed head-on with the Eight Precepts at the center of the dome.

Before the two attacks even made actual contact, the air in the center was forcibly torn apart by the violent and domineering force.

Black and red lightning exploded outwards like a torrential rain, tearing away the remaining rock layers one by one.

Luffy's feet sank into the ground instantly, and his arms were slightly bent by the terrifying force emanating from the Eight Precepts.

But he didn't back down. Instead, he gritted his teeth, poured even more Conqueror's Haki into his fist, and forcefully pushed Kaido's spiked club away.

Kaido turned his body and the Eight Guardians swept across from the other side.

Luffy anticipated the attack's trajectory, leaned back, and the spiked club grazed his nose, but the force of the wind still tore a bloody gash across his face.

The next moment, Luffy was already close to Kaido.

"Rubber Rubber - Overlord Spear!"

The fist, wreathed in Conqueror's Haki, avoided the thickest part of the dragon scales and slammed heavily into Kaido's old wound on his abdomen, which had been repeatedly torn open by Oden, Akazaya Nine, and Victor.

puff!

Hot blood gushed out.

Kaido staggered back half a step, but just as Luffy was about to give chase, he suddenly raised his knee and slammed it into Luffy's abdomen.

Luffy spat out blood, and before he could even leave the ground, the Eight Precepts fell heavily from above.

Boom!

Luffy was smashed into the rock.

Before Kaido could pull out his spiked club, his rubber body in the pit suddenly bounced back due to the elasticity generated by the compression.

Luffy spun out of the ground, his right leg, wrapped in Haki, slammed into Kaido's jaw.

boom!

Kaido's head was kicked backward, and blood splattered from the corner of his mouth.

Luffy didn't stop, his fists raining down like a storm.

Kaido used the Eight Precepts to continuously parry, and the two figures fought their way from the center of the dome to the edge. Just as they were about to fall, they simultaneously shattered the rock wall and rushed back to the battlefield.

They completely abandoned the attempt to probe.

There was no elaborate plan, and no one to assist them.

It's a pure contest of fists, spiked clubs, Conqueror's Haki, and who falls first.

Kaido slammed Luffy into the ruins with a single blow, and Luffy burst out from the rubble, smashing the scales on Kaido's chest with his fist.

Luffy was swept into the air by the dragon's tail, then compressed his legs in mid-air, using the momentum to crash back into Kaido.

Each collision caused the entire ghost island to tremble violently, as if the island might completely collapse at any moment during the battle between the two.

The drunkenness on Kaido's face gradually faded.

What replaced it was a long-lost sense of seriousness and enjoyment.

"That's it!"

"This is exactly what I wanted!"

The Eight Precepts descended with Conqueror's Haki, blasting Luffy back head-on.

Only by constantly overcoming the impossible can one be qualified to stand at the top of this vast ocean!

Luffy rolled dozens of meters across the ground, his hands digging into the rock to forcefully stop himself. He spat out the blood in his mouth and stood up again.

"I don't care about the top."

Luffy wiped the blood from the corner of his mouth, his eyes remaining unwavering.

"All I know is that I'm going to beat you to a pulp today!"

Kaido let out a hearty laugh, then completely enveloped the Eight Guards in Conqueror's Haki.

"Thunderous Eight Trigrams!"

A flash of black and red lightning streaked past.

Luffy used Gear Second to increase his speed, narrowly passing under the spiked club. His fist rapidly expanded, and he slammed it into Kaido's chest with the power of Gear Third.

Kaido, however, seemed to have anticipated his actions, and the Eighth Prince forcibly turned back in mid-air.

"Roaring Eight Trigrams!"

boom--!

The spiked club struck Luffy's shoulder from the side, sending him crashing into the edge of the dome.

Large amounts of rocks broke off from Oni Island and fell towards the Flower Capital below, only to be shattered by the shockwave generated by Susanoo.

Luffy burst out of the smoke and dust, his body rapidly expanding in mid-air.

The combination of flexibility and Armament Haki allowed him to change direction continuously in the air, dodging Kaido's follow-up attacks.

"King Ape Spear!"

The enormous fist slammed head-on into Kaido's face.

Luffy did not maintain Gear Fourth. Instead, he immediately returned to his original state after the attack hit, used Gear Second speed to circle behind Kaido, and then attacked Kaido with Gear Third punch.

He began to briefly combine the speed of second gear, the power of third gear, and the elasticity of fourth gear.

Continuously switch forms during battle to achieve the strongest burst of power with less consumption of Haki.

Kaido also showed no mercy.

Black and red lightning kept exploding in the sky above the ghost island.

Those on the lower battlefield could no longer see the two men's movements.

Judging from the continuous loud noises, the battle that would determine the outcome of the war was not yet over.

……

After another head-on collision, Kaido suddenly twisted the Eight Precepts and used the end of his spiked club to break through Luffy's defense, then slammed the club into his chest.

boom--!

Luffy's body flew sideways and crashed heavily into the rock wall at the edge of the dome.

This time, no sound came from the ruins for a long time.

Kaido did not give chase.

He stood still, carrying the eight precepts on his shoulder, waiting quietly.

A few breaths later, a blood-stained hand emerged from the rubble.

Luffy pushed away the rock that was pressing down on him and stood up again, swaying slightly.

His breathing was completely disordered, his forehead and chest were covered in blood, and his arms were trembling.

But he was still smiling.

"It's not over yet."

Kaido looked at him, his approval growing stronger.

"My domineering aura is almost exhausted, and my body has reached its limit."

"Shall we continue?"

"certainly."

Luffy looked up and glanced into the distance.

Viktor is protecting the Flower Capital for him, while his companions are still fighting desperately below.

Everyone is waiting for him to win.

Luffy bit his arm, blowing a large amount of air into his muscles.

"Because everyone is waiting for me!"

boom!

White steam bursts out from around the body.

His body, covered in Armament Haki, rapidly expanded, and black and red Conqueror's Haki lightning coiled around his thick arms.

Four gears!

Luffy knew it very well.

This is the last time he will maintain this form.

If he cannot defeat Kaido before his Haki runs out, he will no longer have the strength to continue fighting.

Kaido clearly saw this as well.

"Are we going to bet everything on this one round?"

Luffy did not answer.

His body vanished abruptly due to the elastic force.

The next moment, countless fist shadows appeared simultaneously from all directions.

"Rubber Rubber - King Ape Crow Cannon!"

Bang bang bang!

Fists wreathed in Conqueror's Haki rained down like a storm.

Kaido wielded the Eight Blessings to parry, but the dense attacks still broke through the defenses from different angles.

The fists pounded into his chest, shoulders, and abdomen, shattering the hard dragon scales piece by piece.

The wound that Victor had previously inflicted reopened.

Blood quickly stained half of Kaido's body.

Kaido roared and swept through the Eight Guardians, but Luffy used Gear Fourth to change direction in mid-air, passing over the spiked club, and concentrated all his Conqueror's Haki into his final punch.

boom!

The fist struck Kaido squarely in the face.

Kaido's massive body was blasted into the ruins, smashing through several remaining rock peaks before finally being completely swallowed up by the billowing dust.

Luffy landed back on the ground.

The steam around the fourth gear started to become unstable.

He was breathing heavily, staring intently into the depths of the ruins.

No sound.

There was no action taken.

A slight smile had just appeared on Luffy's face.

next second.

The heavy sound of the Eight Precepts being dragged across the rocks slowly drifted from the smoke and dust.

Kaido stood up again.

"Your fists are now a real threat to me."

Kaido gripped the Eight Rings tightly, his expression devoid of mockery.

"But in a battle, it's not about who wants to win more, but who will necessarily win."

He watched as Luffy's Haki kept flashing.

"Straw Hat Boy, you've reached your limit."

Luffy did not refute.

The fourth gear will soon be discontinued.

All that remained in his body was the domineering aura of his final attack.

If this punch misses or is blocked by Kaido, the battle will end.

Luffy concentrated all his Conqueror's Haki into his right fist, compressing his arm behind him as his rubber muscles and Haki roared under the strain.

Kaido also raised the Eight Precepts.

The black and red lightning gradually condensed into an almost tangible aura of dominance, causing the entire sky to crack open from the center once again.

This time, he didn't threaten Luffy with the Flower Capital, nor did he turn around and attack Victor, who was lifting Onigashima.

Kaido chose the most positive approach in responding to this enemy who had gained his approval.

"Come on, Straw Hat Boy."

"Let me see just how far your dreams can go!"

Luffy roared and his compressed body shot out suddenly.

"Rubber Rubber - Tyrannosaurus Rex Cannon!"

The fist collided head-on with the Eight Precepts in mid-air.

Boom—!

The berserk Conqueror's Haki transformed into a black and red pillar of lightning, shooting straight into the sky.

Initially, the two sides were briefly locked in a stalemate.

Luffy gritted his teeth and poured the last bit of Haki into his fist, actually forcing Kaido back half a step.

But it was only half a step.

Luffy's fist began to flash with Conqueror's Haki.

The injuries accumulated from previous battles, the immense energy drained by Gear Fourth, and the nearly depleted Haki all erupted simultaneously at this moment.

His arms began to tremble.

Kaido, however, still possesses the power to continue swinging his bat.

The Eight Precepts gradually pressed down on Luffy's fist.

A hint of regret flashed in Kaido's eyes.

"What a pity."

"You're not qualified yet!"

In the next instant, Kaido unleashed all his remaining power.

boom--!

Luffy's Conqueror's Haki defense was directly penetrated by the fist.

The eight precepts struck his chest heavily.

Blood spurted from Luffy's mouth.

The fourth gear disengages instantly.

His body returned to normal, and as if he had lost all his strength, he flew backward, smashing through several suspended rocks before falling deeper into the interior of the ghost island.

The straw hat also fell off his head and slowly floated down in the strong wind.

Kaido stood on the edge of the shattered dome, without letting out a triumphant laugh.

He simply stared silently in the direction Luffy had fallen, a look of emptiness on his face that even he couldn't understand.

After a while.

Luffy's energy began to weaken rapidly.

Below Ghost Island.

Viktor's Rinnegan suddenly contracted.

He was still holding up the entire island, his hands unable to let go, but he could no longer sense Luffy's presence.

In that instant, the cracks on Susanoo's arms suddenly widened.

Under its immense weight, Oni Island sank a distance back towards the Flower Capital.

Viktor immediately gritted his teeth and forcibly stabilized Susanoo.

Luffy's voice.

Disappeared.

At the edge of the dome, Kaido bent down and picked up the straw hat that had fallen among the rubble.

He stared at it silently for a moment, then finally released his grip, letting the straw hat be swept downwards by the gale.

The royalist's surveillance capabilities have already transmitted the battle results back to the interior of Ghost Island.

The next moment, her trembling voice was broadcast throughout the entire island via a Den Den Mushi (transparent telephone snail).

"Straw Hat Luffy has lost his life!"

"The final battle on Ghost Island Dome is over!"

"The victor—Lord Kaido!"

The entire ghost island fell into a brief, deathly silence.

Kaido picked up the Eight Precepts again, stood on the edge of the broken dome, and looked down at the samurai and Straw Hat crew members who were still resisting below.

His voice, like thunder proclaiming the end of the world, resounded across the battlefield.

"Straw Hat Luffy—"

"Defeat".
