One Piece: With Sign-in System

Just as Ron had declared—Marineford was nothing more than the prelude.

Now, the true war had begun.

The First Division, the full fleet of the Beasts Pirates, surged forward with overwhelming momentum, charging straight into the red waters beneath the Red Line.

The moment their ships came into contact with the Marine frontline fleet, chaos erupted.

Without the slightest hesitation, Jack issued the order.

"Fire the cannons!"

The Marines responded immediately with a barrage of their own.

In an instant—

The crimson sea thundered with cannon fire, deafening roars echoing through the sky and sea.

The war that could change the entire world had officially begun.

And as though set alight by a spark, news of the outbreak spread like wildfire across the New World.

The World Economy News Paper caught wind of it and immediately dispatched their fastest channels to report it globally.

Within a single day, flocks of News Coo flew in all directions over the ocean, scattering newspapers like rain over every island in the sea.

Just the headline alone…

…was enough to send a shiver down the spine of every person who read it:

[A War That Will Decide the Fate of the World Has Begun!]

…

Alabasta.

In the royal palace, Princess Vivi held the newspaper with both hands, worry clouding her eyes.

"Did it really have to come to this…?"

"Father," she looked up, voice trembling slightly. "Do you think he can really bring down the World Government?"

"I don't know," King Cobra replied solemnly, seated beside her.

He looked down at the same headline she did, his brows furrowed.

"I only know one thing… no matter who wins this war, the world as we know it will never be the same again."

…

Dressrosa.

Inside one of the royal chambers, King Riku sat on his throne, the newspaper resting in his hands like a burden.

Standing below him were Kyros, Rebecca, and Violet.

"…It has begun."

"Grandfather," Rebecca said, a touch of desperation in her voice, "is there really nothing we can do?"

"That man—and Admiral Zephyr—they saved Dressrosa."

"Rebecca," Violet gently placed a hand on her shoulder, quietly reminding her, "you mustn't speak to the king like that."

"It's alright," King Riku said, lifting his gaze to meet Rebecca's eyes.

He spoke seriously, as though passing on a truth she had to accept.

"Rebecca, in this war, we truly can do nothing. Even if we sent all of Dressrosa's forces to aid them, it would only be a meaningless sacrifice."

"All we can do now… is wait."

…

Whole Cake Island.

"Mom! They've started fighting!" Perospero exclaimed excitedly, licking his candy-coated fingers. "Now's the perfect time to take over the territories left behind by Whitebeard and Kaido!"

"Forget it."

"…Eh?"

Big Mom raised her head from the cake she was devouring, her eyes dark and feral.

"I said forget it."

Her voice dropped, dangerous and ice-cold.

"Did you not hear me? Or… do you want that monster to show up here again?!"

Perospero instantly turned pale, the blood draining from his face.

Nearby, Katakuri, Smoothie, Cracker, and the others—just the memory of that man sent a heavy chill through their hearts.

That person—neither human nor god, yet somehow both—had left a fear in them that would never fade.

…

Holy Land — Mary Geoise.

The entire World Government was in chaos—people moving back and forth, the air tense with urgency.

Inside one of the grand meeting rooms—

"Jack and Queen, leading the Beasts Pirates, have launched a full frontal assault. They've already clashed with the Navy's first defensive line." a subordinate reported crisply.

Kong listened quietly, then gave a small nod. His sharp gaze swept over the others in the room—Sengoku, Tsuru, and the CP0 commander.

"It's begun. Proceed according to the plan."

"Do whatever it takes to stop them before they reach Mary Geoise"

Meanwhile, with Jack and Queen spearheading the charge, the Beasts Pirates broke through the first Marine defensive line in the red waters—only to find themselves face-to-face with an even larger fleet of Marine battleships.

These ships opened up with overwhelming firepower, hammering the Beasts Pirates with relentless barrages.

"Sir Jack! We're almost out of cannonballs! What now?!"

"The Navy's firepower is too intense!"

Jack's eyes were bloodshot, his expression unhinged and savage. "This? This pathetic barrage? You call this firepower?!"

"Get that damn ship over there! Now!"

"W-What?!" The crew stared at him in disbelief.

"Is there a problem?"

"N-No sir, but… with this level of fire, our ship won't make it through!"

"Then figure out a way and get it done!"

"Ehh?!"

"…I'll handle it," came a gruff voice.

With a cigar clenched between his teeth, Queen stepped forward and stomped hard on the deck. His enormous body launched high into the air—soaring toward the Navy fleet.

In midair, his form shifted and expanded, morphing into a gigantic brachiosaurus. Ignoring the hail of cannon fire, Queen came crashing down on one of the Marine ships.

BOOM!

The massive battleship shattered beneath his weight, sinking into the sea in seconds.

"It's Queen the Plague!"

The Marines instantly fell into disarray, and their coordinated bombardment faltered.

Jack's eyes narrowed. He wasted no time.

"Now! Everyone who can transform—charge!"

From the Beasts Pirates' fleet, dozens of figures launched into the air—transforming mid-leap into saber-toothed tigers, wolf spiders, triceratops, and other monstrous forms—raining down like meteors on the Navy ships.

Chaos erupted.

The Marine fleet fell into utter disorder, unable to hold formation.

The Beasts Pirates' ships pushed forward, ramming into the Navy line, and soon it turned into a brutal melee—swords clashing, fists flying.

In terms of sheer individual combat strength, the Zoan-type Devil Fruit users of the Beasts Pirates completely overpowered the average Marines.

Before long—

Jack, leading 500 Zoan-ability users, forcibly carved a bloody path through dozens of battleships, cutting deep into the heart of the red waters.

Right behind them came the Second Division—the Revolutionary Army, led by its four Commanders. They followed the path cleared by the Beasts Pirates, breaking through both the first and second Marine defensive lines, pushing deeper into the heart of the red sea zone.

Just then—

More Marine fleets appeared from the left and right flanks, forming a pincer attack in coordination with the remaining ships from the first and second lines. Together, they closed in on the Beasts Pirates and the Revolutionaries.

"Open fire!!" Vice Admiral Onigumo roared, brandishing his blade.

Nearly a hundred Marine ships launched a simultaneous volley—the sea thundered, as cannon fire lit up the sky.

Under the intense bombardment, the combined fleet of the Beasts Pirates and Revolutionaries suffered heavy losses—over a dozen of their ships were sunk in minutes.

And just as the Marines prepared for another devastating round—

The sky changed.

Ten colossal airships suddenly appeared above the battlefield.

"Heaven's Judgment — Black Coffin!"

A woman's voice rang out from above, clear and chilling.

From high above, massive steel pillars came plummeting from the heavens—each one carrying terrifying destructive force and landing with pinpoint precision on Marine ships.

CRASH! BOOM! BOOM!

Battleships were torn apart on impact.

The explosions sent violent shockwaves across the sea, rocking nearby ships and disrupting their firing sequences. The entire battlefield was suddenly bathed in fire and chaos, a chain reaction of detonations lighting up the ocean.

"They're attacking from the air?!"

Vice Admiral Onigumo gritted his teeth, glaring at the sky above—well beyond the range of cannon fire.

"Calm down," said Chaton, one of the three commanders of the Red Sea's triple-layered defense.

"She can't launch an attack like that again so easily. That kind of technique takes a toll. Now that the Beasts Pirates and the Revolutionaries are surrounded, we need to press the advantage and finish off their forc—"

He didn't finish his sentence.

A Marine burst in, panic written all over his face.

"Sir! We're under attack from the rear!"

"What?!"

"It's—It's Diamond Jozu, leading the remnants of the Whitebeard Pirates!!"
