One Piece: Navy Traitor, I Marry the Female Emperor To Rule the Sea

New World, Dressrosa!

At this very moment, as an immense pillar of destructive light descended, casting despair upon everyone present, Shiro's voice echoed across the battlefield. Suddenly, the seas around the island roared to life with an incredible surge.

The sky was filled with a column of destructive light, while the raging seas below responded with a fierce storm, clashing head-on.

Upon witnessing this, Imu, the secret ruler of the pirate world, couldn't hide his surprise.

"Is this... the Ancient Weapon, Poseidon!?"

Boom!

Splash!

Then, something unbelievable occurred. Just as the pillar of light was about to obliterate everything, Dressrosa vanished from the ocean's surface, swallowed by the raging seas.

Among those on the island, many caught glimpses of colossal sea creatures stirring the waters beneath the waves. Veterans like Garp and Sengoku felt a sense of awe, realizing that Shiro truly wielded the power of the Ancient Weapon, Poseidon, and that it had already awakened.

Boom! Boom! Boom!

The massive destructive light finally struck the ocean, creating a gigantic crater in the sea, spanning tens of thousands of meters, and forming a terrifying whirlpool.

However, despite the devastation, neither Imu nor the Five Elders showed any signs of relief, their expressions grew even more tense. Even Imu, accustomed to controlling everything, had a flicker of panic in his eyes for just a moment.

How many trump cards does this young man, who dares to defy the gods, still hold!?

When the devastating attack finally dissipated, Dressrosa reappeared on the sea's surface, completely unscathed. At that moment, the entire world—civilians, pirates, and warriors alike—focused their gaze on the young figure standing in mid-air.

He was Shiro, the indomitable hero leading the fight against the Marine and the World Government.

Behind him stood Shirahoshi, the beautiful and powerful mermaid princess, smiling proudly. "Shiro, did I do well?"

"Yes," Shiro replied calmly. "You've grown stronger, no longer the timid Shirahoshi."

Shirahoshi's smile widened, revealing her pride as Poseidon, the ruler of the sea, invincible in her domain. But for her safety, Shiro soon instructed her to retreat into the depths, where millions of Sea Kings awaited, a force capable of shaking the entire world.

"You think controlling the Ancient Weapon Poseidon secures your victory? Foolish boy!" Imu growled, his patience reaching its limit. Today, there would be no peace between Shiro, the Central Authority, and the World Government.

Without hesitation, Imu's eyes turned cold, the Ancient Weapon Uranus glowing ominously. At that moment, devastating beams of light began to appear across the world, from Alabasta to other major kingdoms, ready to unleash chaos.

Watching Imu prepare to unleash his power, Shiro's lips curled into a sneer.

"Do you honestly believe you can suppress me with this light show?"

"You dare mock me!?" Imu's voice thundered. "I am the eternal god of this world, and all others are mere slaves to power!"

Imu's arrogance was palpable as he descended from Uranus's protection, confronting Shiro directly. Seeing this, the mighty warriors like Whitebeard, Hawk Eyes, Aokiji, Garp, and Borsalino gathered behind Shiro.

They had finally seen the true face of the World Government—merciless and manipulative. Even the once-loyal Kong was left disillusioned, realizing that their sacrifices meant nothing to those in power.

"Enough of this! You ants are not worthy of facing me!" Imu declared. With a command, his body began to radiate an intense light that nullified the abilities of Devil Fruit users.

Whitebeard and the others felt their powers fade, their strength sapped as though they were exposed to Seastone. In the face of this overwhelming force, even Shiro's Devil Fruit powers were weakened, though not completely suppressed.

Despite this, Shiro remained unfazed. He had prepared for this moment, knowing that his true ace was yet to be revealed.

"Are you not afraid?" Imu questioned, confusion creeping into his voice as he saw Shiro's calm demeanor.

"Spare me the theatrics," Shiro replied with a cold smile. "In two hours, Imu, your reign will end. You will die."

These words ignited a burning rage within Imu. "Then let the world bear witness! For all who dare defy me, there will be no mercy!"

The Ancient Weapon Uranus unleashed a barrage of destructive beams, aimed to obliterate life itself, while Imu wielded a radiant blade, its edge like a crescent moon, lunging towards Shiro.

But just as Imu's attack closed in, a figure wrapped in blazing sunlight emerged from the storm, standing fearlessly against him.

High above, a colossal warship appeared in the sky, hurtling toward Uranus like a meteor, ready to crash into the Ancient Weapon with unstoppable force.
