Grand Line, a certain sea battlefield.
Smoke choked the air, and bodies lay strewn across the shattered decks and ruined shorelines.
This was the final defensive line of the World Government's Allied Forces. Five hundred thousand elite troops had gathered here, equipped with the most advanced cannons and Pacifistas.
But now—
Those five hundred thousand were in full retreat.
They were being hunted down by only a few hundred ninja.
"Devils!"
"You can't even see them! There's just a flash of light—and then someone's dead!"
"The commander's down! The general too! Run—run!!"
At the heart of the battlefield, two figures moved like phantoms through the chaos.
One was a streak of golden light—Minato Namikaze.
The other was a blue afterimage like flowing water—Tobirama Senju.
They unleashed no earth-shattering ultimate techniques. Instead, they relied purely on kunai and their transcendent mastery of the Flying Thunder God Technique.
Swoosh! Swoosh! Swoosh!
Minato flicked dozens of specially made kunai into the air.
His figure vanished.
In the next instant, golden flashes erupted across dozens of positions on the battlefield at the same time.
Thud! Thud! Thud!
The officers directing the cannons collapsed simultaneously, falling before they could even react.
Minato reappeared atop a tank barrel, a calm smile on his face. The kunai in his hand dripped silently.
"So this is warfare in another world?" he said softly.
"Too slow."
"No matter how many there are, they can't keep up."
On the opposite side, Tobirama was even more merciless.
He formed hand seals, and the surrounding seawater roared.
"Water Release: Water Severing Wave!"
A razor-thin torrent of pressurized water tore across the battlefield, cutting through armor and formations alike as if they were paper.
Soldiers fell in rows, the line instantly collapsing.
Tobirama's gaze remained cold.
"The technology here… is far behind."
He vanished again.
"Flying Thunder God Slash!"
In a blur, he appeared behind a Devil Fruit user attempting an ambush and ended the threat in a single, decisive strike.
Half an hour later—
The five-hundred-thousand-strong army was completely broken.
Over three hundred thousand were lost. The survivors dropped their weapons, kneeling and trembling as they surrendered.
"Minato, finish securing the area."
Tobirama sheathed his blade and raised the communicator.
"His Majesty has ordered a halt to the advance."
"All units are to regroup and proceed to the final battlefield."
"Understood," Minato replied, looking toward the horizon.
"It seems the World Government plans to stake everything on one last stand."
…
Three days later.
Ten thousand meters beneath the sea, in the waters surrounding Fish-Man Island.
Once a paradise on the road to the New World, it had become a true Shura field.
Because of Dragon and Imu's so-called "Absolute Alliance," every remaining foundation of this world had gathered here.
The sea churned into a dark, chaotic mass.
As far as the eye could see, warships, submarines, and even colossal Sea Kings filled the waters.
An army of ten million.
This was no exaggeration.
Every soldier who could still fight, every bounty hunter, every pirate, even prisoners released and armed as expendable forces—everything had been thrown into this battle.
Fish-Man Island Plaza.
Dragon stood atop a high platform. Beside him were Imu, eyes lifeless, and the remaining Seven Warlords.
"Is everything prepared?" Dragon asked, his voice heavy.
"Ready," Ivankov replied, gripping a steel pipe and staring into the abyss above.
"Pluton is fully charged. Its cannon is aimed at the surface."
"The core of Uranus can still fire once," another voice added. "Even if it's a suicide strike."
Jinbe gestured toward the distant Sea Kings, restless and immense.
"Princess Shirahoshi was taken by that man… but through drugs and ancient technology, we've forcibly seized control of this Sea King army."
Sea, land, and sky.
Technology and brute force intertwined.
This was the final roar of a world fighting for survival.
"They're coming…"
Imu suddenly looked up. A faint red glow flickered in those ripple-patterned eyes.
"I can feel it."
"That repulsive aura… approaching at incredible speed."
…
Above the sea.
The previously calm surface began to tremble.
This wasn't a wave.
The sea level itself was sinking.
Hum—
The sky fractured.
A massive warship wreathed in cold, faint light tore through space itself, hovering directly above Fish-Man Island.
Around it—
Countless ninja clad in black armor stood in perfect formation, walking on chakra as if they were heavenly soldiers.
At the bow stood the legends of the Ninja World—Madara, Hashirama, Obito, Kakashi, Itachi, Shisui…
Their combined presence alone made the army below struggle to breathe.
On the throne at the bow, Tobirama slowly opened his eyes.
"Ten million troops?"
"Ancient weapons?"
A trace of disdain curved his lips.
"Is this your final struggle?"
"Dragon. Imu."
He rose and stepped to the railing, his Hokage cloak snapping in the sea wind.
"It certainly looks impressive."
"But that's all it is—impressive."
"Since you've all gathered here, it saves me the trouble of searching the world."
"Let a single battle decide its fate."
The final war—
Begins.
