One Piece: With Sign-in System

Holy Land, Mary Geoise.

Flames, hurricanes, magma, lightning, freezing winds, shockwaves, laser beams—powerful forces of every kind clashed in the skies and on the earth. Towering, majestic buildings crumbled like paper as the ground cracked open. Mary Geoise looked like it was about to be shattered from the heavens above down to its very core.

The Celestial Dragons within the city watched this apocalyptic scene unfold, trembling with sheer terror.

"Where are the Five Elders? Why haven't they appeared yet?!"

An older Celestial Dragon cried out, his face pale with horror. "Use that thing—use it now! If we don't, the Holy Land will be destroyed!"

"Yes! That treasure! The Grand Treasure!"

"Activate it! Hurry! We're not dying here!"

At the highest window of the World Government castle, the Five Elders stood, gazing upon Mary Geoise as it teetered on the edge of annihilation.

"If the castle gets destroyed, we can always rebuild it. But if we lose this war… we'll lose everything."

The bald Elder, cradling the original Kitetsu blade, spoke with a chilling calmness in his eyes.

"This should be the full force that guy could gather. Meanwhile, we still haven't revealed all of our cards."

The blond-haired Elder crossed his arms, his voice cold as steel. "To think this ragtag group could bring down the World Government… they've clearly underestimated the strength we've built up over eight hundred years."

Kong, Garp, the Five Elders, the legendary Grand Treasure said to summon the ancient weapon Uranus… and the one who resides in the deepest depths of Pangaea Castle—

This is the true power of the World Government: rulers of the seas for eight centuries, and masters of the entire world!

Unshakable. Unmatched.

…

"Tornado... Scourge Winds!"

Kaido, in his massive dragon form, shredded through the surrounding frost, coiling and spiraling through the sky. A hurricane-level wind pressure burst out in every direction like blades, slicing apart the battlefield.

Even Aokiji was cleaved in two by one of those wind blades. His body of ice split down the middle—but not a single drop of blood spilled.

But clearly, Aokiji alone couldn't contain Kaido's destructive rampage.

At the foot of the World Government's castle, Kong watched the chaos unfold. His brows furrowed as he glanced at the battlefield, then up toward the highest tower where the Five Elders stood.

"Garp, you... Ah, never mind."

Kong let out a long sigh.

Then he stomped his foot down and launched himself skyward toward Kaido. His massive, muscular right arm pulled back, now coated in a hardened layer of Armament Haki.

With a thunderous swing, he drove a monstrous punch right into Kaido's dragon skull.

BOOM!

With a bone-shaking sound, the colossal dragon was sent crashing down from the skies, slammed violently into the earth!

"It's the Supreme Commander!"

"Commander Kong has entered the battle!"

"He took down one of the Four Emperors—Kaido—with just one punch?! Unreal!"

"No wonder they call him the Supreme Commander!"

The Marines and World Government elites who witnessed the scene suddenly felt their morale ignite. Spirits surged high. The crushing pressure they'd been under began to lift.

…

BOOM.

The underground prison quaked from the force of Kaido's impact.

Garp looked up and grinned. "So that old man finally made a move, huh."

Rob Lucci blinked. "Old man?"

"Yeah, I'm talkin' about Old Kong."

"The Supreme Commander?"

"Mhm."

A flicker of shock passed through Lucci's eyes.

As far as he knew, the legendary Kong hadn't made a public move in ages—probably not since Garp had earned the title of "Marine Hero."

Lucci turned to Garp, who was seated calmly outside the prison bars. "Garp-san, you're just sitting here… aren't you worried about not fighting?"

Garp fell silent for a moment before looking up with a smile. "Nah. I've already decided I'm retiring."

Lucci stared at him, stunned.

Draped in his coat of justice, seated cross-legged in front of the cell, Garp lowered his head, clenched his fists, and muttered under his breath:

"I'm too old now. This ocean's justice and order... shouldn't be carried by these old bones of mine. I've done all I could as a Marine. Now let me be selfish... just this once…"

…

With the arrival of the Phoenix Marco and the Supreme Commander Kong—

The battlefield at Mary Geoise had turned even more chaotic, more apocalyptic.

Logia users, Mythical Zoan users, masters of Haki and raw physical prowess, Paramecia users with bizarre abilities, and elite swordsmen of unmatched skill—all clashing in a maelstrom of war.

The scale was unprecedented.

It could very well be the greatest war in the World Government's entire eight-hundred-year history!

Once-in-a-lifetime. Unrepeatable.

Even Marine officers who had mastered the Six Powers and two types of Haki weren't qualified to set foot on the core battlefield of this war.

And still—

Neither side had yet unleashed their full strength.

They were all holding something back.

Just like Ron once said:

Even the so-called Great War at Marineford was only the prologue to this.

Compared to the war that would decide the fate of the entire world, that "summit war" was nothing more than a footnote.

And the outcome of this battle—

Not even someone who had honed Observation Haki to its very peak could predict it.

…

At the highest point of Pangaea Castle, the Five Elders stood silently by the window, overlooking the battlefield below, their expressions cold and unreadable. They waited—calmly, patiently—for the moment to strike.

Hovering above Mary Geoise, atop one of the colossal floating island fragments shattered from the sky, stood the Dark King, Rayleigh, and Black Arm Zephyr.

Rayleigh took a casual sip from his flask, his eyes crinkling with amusement.

"The Five Elders sure know how to hold their nerve. Still haven't made a move, have they?"

Zephyr stood with arms crossed, his gaze heavy.

"Even Kong has stepped in… but Garp's still a no-show. Looks like he's made up his mind not to get involved."

Rayleigh chuckled and lifted his flask again.

"Isn't that perfect? I'm not exactly eager to go toe-to-toe with Garp's Iron Fists."

Then, with a laugh, he handed the flask over to Zephyr.

"Who would've thought I'd one day fight side-by-side with Black Arm Zephyr?"

Zephyr took a deep swig, his voice thick with irony.

"Believe me, it'll be the first and last time."

He let the liquor burn down his throat before adding,

"Good and evil… they've always intertwined into chaos. The lines on this sea were never clean. Pirates and Marines—there's no absolute justice. Took that damn kid to finally open my eyes to that."

…

Elsewhere, a man in a black cloak ascended the Red Line—one arm missing, a long sword at his hip. Step by step, he made his way toward the thunderous epicenter of Mary Geoise, undeterred by the shaking earth and deafening blasts.

Deep within Pangaea Castle—

At the heart of the world, where the twenty swords of ancient kings stood thrust into the ground around the Empty Throne, a lone figure sat—enshrouded in pitch-black robes, a sovereign of shadows.

It was Imu.

They slowly raised their gaze toward the sky above.

Their eyes—bottomless, still, as if belonging to some eternal void—pierced through the layers of stone, steel, and sanctity to the heavens high above Mary Geoise.

And there—floating alone amid the sea of clouds—

Ron stood.

Clad in flowing black, his dark hair dancing with the wind, he hovered in the skies like a sovereign descended from the heavens. With hands calmly folded, he peered down with his Tenseigan Eyes—those deep blue orbs reflecting no emotion, only unwavering resolve.

From above the clouds, he overlooked all of Mary Geoise… and the towering seat of world domination—Pangaea Castle.

He had already sensed Imu's presence.

And Imu, in turn, had noticed him too.

Heaven and earth…

Sky and land…

Two unseen kings, locked in a gaze across realms.

A silent confrontation that could shatter the world itself.
