One Piece: With Sign-in System

News of the massive fleet crossing the Red Line at an altitude of ten thousand meters spread like wildfire, shaking the entire world.

Even the World Government was thrown into chaos.

Panic erupted within Marine Headquarters and Mary Geoise as officials scrambled to respond.

Kong, the Supreme Commander of the World Government, and Sengoku, the former Fleet Admiral, immediately began executing their pre-arranged battle strategies.

The world braced itself for the inevitable war.

…

New World – Punk Hazard

By the time the remnants of the Whitebeard Pirates, the Revolutionary Army, and the Straw Hat Alliance had all arrived at Punk Hazard, every major force participating in this world-shaking battle had gathered in full.

…

On this fateful day, the sky was clear and cloudless, the sea a vast stretch of deep blue.

Countless ships anchored in the waters surrounding Punk Hazard, so numerous that they covered the horizon.

The Straw Hat crew stepped onto the island's shores, taking in the sight of the countless pirate crews assembled.

"That's Chinjao, the leader of the Happo Navy," Jinbe noted.

"That's Cavendish of the Beautiful Pirates."

"Wait… even the Giant Warrior Pirates are here?!"

The sheer number of high-profile figures left Jinbe genuinely surprised.

"Wh-What the hell…?!"

Usopp's eyes darted from one pirate to another, his breath hitching.

"Are all of these big-shot pirates gathered because of that person?"

At his words, a voice scoffed.

"No. We weren't summoned by anyone."

The speaker was Sai, the current leader of the Happo Navy. He turned toward the Straw Hats with a sharp gaze.

"We came here because we wanted to fight."

Beside him, the Destruction Cannon Ideo cracked his knuckles with a grin.

"I've had enough of the World Government's arrogance. Those bastards have looked down on us for too damn long."

Cavendish twirled a rose between his fingers, his radiant beauty practically shining in the sunlight.

"A battlefield of this scale… it's the perfect stage for me to showcase my charm and power." He smirked. "There's no way I'd miss such an opportunity."

Just then, his eyes landed on a certain straw hat-wearing figure.

Cavendish froze, his smirk vanishing as he stepped closer.

He stared at the young man with an intense gaze.

"You… Are you Straw Hat Luffy?"

Luffy blinked, confused.

"Yeah. What about it?"

Cavendish squinted at him, tilting his head.

For several seconds, he examined Luffy—looking him up and down, from head to toe.

Then—

"What the hell are you doing?!" Luffy frowned. "You wanna fight or something?!"

"No."

Cavendish rubbed his chin thoughtfully, his tone laced with genuine curiosity.

"You're… even more ordinary-looking than I imagined."

Luffy's brow twitched.

"You… WHAT?!"

Cavendish ignored his outburst, continuing in a matter-of-fact tone.

"You don't seem particularly strong. How in the world did you cause such a massive commotion during the Marineford War?"

Luffy's face darkened.

"You wanna say that again?!"

"I'm just stating the truth."

The two were seconds away from breaking into a full-blown shouting match when—

A cold, sharp voice suddenly cut through the tension.

"Fighting is prohibited here."

Everyone turned toward the speaker.

A woman stood there—tall and elegant, with long, flowing blue hair tied into a high ponytail.

She wore a white coat, and at her waist hung two swords.

Her presence alone radiated an aura of danger—a sharp, chilling intensity that sent shivers down the spine.

A murmur ran through the crowd.

"That's… the Swordmaster of the Calamity from the Skies."

Even some of the more battle-hardened pirates lowered their gazes in respect.

"What overwhelming pressure…"

"She's definitely at the Grandmaster Swordsman level."

Several renowned pirates, each with a bounty exceeding a hundred million, couldn't help but regard the woman with newfound seriousness.

Cavendish took another glance at Kuina, then turned away from Luffy, dropping the argument.

"I'll let it go this time… for her sake," he muttered. "But next time, on the battlefield, we'll see who stands at the top."

Luffy frowned as he watched Cavendish's retreating figure.

"What the hell is his problem?" he grumbled. "That curly-headed guy is acting all weird—I didn't even do anything to him!"

Kuina's gaze briefly flickered toward Zoro.

Zoro, in turn, was already locked onto her, one hand resting on his sword hilt, a flicker of battle intent flashing in his eyes.

Yet, after just one glance, Kuina turned and walked away.

…

…

At this moment, seven massive fleets had finished their preparations on the open sea.

Every crew member stood at attention, their eyes fixed on the shores of Punk Hazard.

Biting down on a cigar, Capone Bege exhaled a puff of smoke as he gazed at the coastline, murmuring,

"…At this point, half the top forces of the Grand Line are gathered here."

"What a damn sight to behold."

Chinjao, the former leader of the Happo Navy, rubbed his bald head, his tone tinged with amusement.

"If the Marines saw this scene, they'd probably piss themselves in terror."

Across the ships, many pirates swallowed hard as they turned their gaze toward the legendary figures standing on the shore.

- Rayleigh, the Dark King

- Zephyr, the former Marine Admiral

- Kaido, one of the Four Emperors

- Monkey D. Dragon, the leader of the Revolutionary Army

- Boa Hancock, the Pirate Empress

- Bartholomew Kuma, the Tyrant

- Marco, the Phoenix

- Portgas D. Ace, Fire Fist

- Sabo, the Revolutionary Chief of Staff

- Kuina, a Grandmaster Swordsman

And then—

Before all eyes, a single figure stepped forward from between Hancock and Kuina.

A tall, lithe yet powerful man, walking ahead of the assembled titans of the sea.

Even Kaido, as proud and defiant as he was, stood behind him with his arms crossed, saying nothing.

He had acknowledged this man's strength.

Every gaze, filled with respect and awe, locked onto him.

Dressed in a black coat, a crimson sword hanging at his waist, long black hair flowing in the wind, he lifted his head.

Under his hair, a pair of piercing blue eyes gleamed with unwavering determination.

His expression remained utterly calm as he surveyed the colossal fleet before him.

Yet, despite his tranquility, a silent pressure radiated from him—one that sent shivers down the spines of even hardened warriors.

Some instinctively gulped, their throats dry from the sheer weight of his presence.

A murmur spread through the ranks.

"…He's like a King."

—

For a fleeting moment, the world fell silent.

The wind stilled.

The ocean held its breath.

Then, his voice—calm yet commanding, rang out over the sea.

"Everyone."

The sheer authority in his tone sent a shockwave through every heart.

"The time has come."

He paused for a second.

Then, with a voice as steady as fate itself, he declared:

"Follow me—and let us overturn this world."

—

A brief silence.

Then—

A thunderous roar exploded across the entire battlefield.

From the Zoan warriors of the Beast Pirates, to the Revolutionary soldiers, to the pirates of the Grand Line—every single one of them raised their weapons, their voices merging into a single, earth-shattering war cry!

Names that shook the seas stood upon the decks, their presence radiating dominance.

- Monkey D. Luffy

- Roronoa Zoro

- Vinsmoke Sanji

- Trafalgar Law

- Eustass Kid

- Killer

- Capone Bege

- Jack

- Queen

Some stood calm and composed, others with razor-sharp gazes, some wearing cold, unreadable expressions, and others already boiling with battle spirit.

All of their combined wills and fighting intent soared into the skies, reaching toward the heavens themselves.
