One Piece: With Sign-in System

"Surround that ship and capture the criminals Ron and Nico Robin," Akainu commanded coldly, his arms crossed and his face as stern as ever.

The adjutant beside him snapped back to attention and responded immediately, "Yes, sir!"

Orders were relayed quickly, and six Marine warships began moving to encircle the Traveler. Marines on the decks of the ships pointed their rifles at the target, ready to fire at a moment's notice.

"If Vice Admiral Garp is getting serious, it seems there's no way out for them," Gion sighed softly, a trace of pity in her voice.

"That idiot!"

Hina slammed her hand against the railing, frustration and anger etched on her face.

Suddenly, Gion's sharp eyes narrowed, and she turned her gaze toward the rear of the fleet.

Two enormous flying slashes, each stretching over a hundred meters, were cutting through the air, heading directly for their warships, including the one they stood on.

Without hesitation, Gion unsheathed her blade. A slash imbued with the full power of a Great Swordsman collided with the incoming attacks, neutralizing them in an explosion of energy behind the fleet.

The vibrations from the clash rippled through the ships, causing the Marines to turn toward the disturbance.

"Enemy attack! Prepare for battle!" Hina and the other officers quickly assessed the situation, their shouts breaking the stunned silence.

Both Akainu and Garp cast a glance to the rear.

A small wooden boat had appeared behind the fleet. Standing at the bow was a figure cloaked in black, twin blades in hand.

The Marines fired their cannons without hesitation, but the figure moved with deadly precision. Seven or eight cannonballs exploded midair, cleaved cleanly by arcs of sword energy. The shockwaves blew back the figure's hood, revealing a girl with piercing eyes and a sharp, determined face.

It was Kuina.

Her blue ponytail swayed behind her as she carried two swords—a Wado Ichimonji, one of the 21 Great Grade Swords, and a blade from the 50 Skillful Grade Swords. Her gaze was locked onto the warships ahead with icy intensity.

"Is she an accomplice of the traveler Ron? To dare attack the Marines…" Akainu's voice turned cold as his gloved right fist began to transform into molten magma, emitting an oppressive heat.

"Admiral Akainu, there's no need for you to step in. I'll handle this," Gion said calmly, her hand resting on the hilt of her sword as she watched Kuina's approach.

Akainu glanced at her from beneath his cap, then nodded. "As you wish."

The magma receded from his arm, and the searing heat dissipated, causing a wave of relief among the Marines.

"Two-Sword Style: Unified Tornado!"

Kuina unleashed a powerful sword technique, sending a spiraling slash of energy barreling toward the warships.

In response, Gion's figure blurred as she used Shave, disappearing from sight and reappearing at the stern of her warship.

With a single horizontal swing of her blade, a streak of pink sword energy tore through Kuina's attack, dispersing the tornado in an instant.

"Are you Ron's ally?" Gion asked with a faint smile. "Your swordsmanship isn't bad. What's your name?"

Kuina remained silent, her sharp eyes fixed on Gion, her grip tightening on her swords.

Meanwhile, aboard the Heart Pirates' ship, panic was setting in.

The six Marine warships were closing in on the Traveler.

"Captain, we need to leave now!" Bepo urged, his voice filled with urgency.

"Yes, yes! That's a Marine Admiral and the Marines's Hero! There's no way anyone could escape from their combined pursuit!" Shachi added, his face pale.

"If we don't leave, once they finish with Ron, we'll be next!"

The two grabbed Trafalgar Law by his arms, their desperation evident.

Law, however, couldn't tear his gaze away from the scene unfolding before him. His eyes flickered with hesitation.

Was this really the end? Was there truly no chance of survival?

Could that man—Ron—really be nothing more than a fool chasing an impossible dream?

No! Something wasn't right.

Just as Law's instincts screamed a warning, the unexpected happened.

The six Marine warships surrounding the Traveler suddenly began to sway violently.

"What's going on?!"

Tina and the other Marine officers were equally stunned, their faces filled with disbelief.

Akainu's brows furrowed deeply. "What's happening?"

"We're not sure! The ships are out of control!" the adjutant stammered, panic in his voice.

Garp's eyes shifted downward, focusing on the surface of the sea. For a moment, a flicker of astonishment crossed his face.

"This is…?!"

On the battlefield, Kuina's slashes were once again intercepted by Gion's swordsmanship. Just as Kuina prepared to strike again, her movements froze.

Her eyes widened in shock as she saw the warship beneath Gion's feet begin to lift into the air.

"What…?" Gion herself faltered, her usual composure giving way to a rare moment of surprise.

In the distance, Law, Bepo, Shachi, and the rest of the Heart Pirates stared in stunned silence.

The six massive warships were rising, defying the pull of gravity as they floated higher and higher above the sea.

"What in the world is going on?!"

Akainu scanned his surroundings, his fury growing. "This has to be…"

"Without a doubt, it's the power of the Float-Float Fruit!" Garp said gravely, standing on the now-levitating deck of his warship.

"What?!" Akainu turned to Garp, his voice sharp. "But the Golden Lion should already be dead!"

They had verified the death of Shiki, the Golden Lion, before this mission—there was no possibility of error.

"You're right," a clear, youthful voice echoed across the ocean.

Everyone—from Akainu and Garp to Tina and the Marines—turned toward the sound.

Hovering above the sea where Garp's punch had sent him earlier, the black-clad figure of the traveler Ron stood, his hands clasped behind his back.

His expression was relaxed, a faint smile playing at his lips as he looked up at the six floating warships and the stunned Marines aboard them.

"The Golden Lion is indeed dead," Ron said, raising his right hand, his palm facing upward.

"But his power didn't die with him."

A mischievous glint flashed in his eyes as he declared, "It now belongs to me."

As Ron's words fell, his ship, The Traveler, broke free from the shackles of gravity. Under countless astonished gazes, it began to ascend rapidly into the sky.

The Marines on the warships looked on, their faces filled with shock, as Ron floated effortlessly above the sea.

Among them, Garp's initial surprise gradually turned into understanding.

"No wonder this brat dared to take such a risk," he muttered to himself, shaking his head.

It became clear now—Ron had learnt the powers of the Float-Float Fruit, ensuring the Marines couldn't trap him.

"What a cunning little rascal," Garp said, his lips curling into a faint grin.

But just as that smile appeared, an intense and suffocating aura surged from beside him. Garp turned his head sharply to see Sakazuki, known as Akainu, glaring coldly at Ron from beneath his cap. His right arm was already transforming into molten magma, its terrifying heat distorting the air around it.

"Sakazuki, this operation is my responsibility," Garp said with a frown.

"This brat has grown too dangerous to ignore," Akainu replied, his tone sharp and unyielding.

Fixing his gaze on Ron, Akainu's molten arm bubbled ominously.

"I must kill him here and now. This sea will not tolerate the rise of a fifth Emperor."

With that, Akainu stomped down, propelling himself off the levitating warship. His magma-coated arm formed into the shape of a ferocious hound as he aimed a devastating punch at Ron, who floated above the sea.

"Hellhound Red Lotus!"

The sheer heat of the attack caused the surrounding seawater to boil violently.

Ron felt the overwhelming destructive power of the incoming strike. He didn't attempt to block it directly but instead relied on his enhanced agility from Moonwalk, propelling himself away at high speed.

As Akainu's magma punch slammed into the sea, the water instantly turned into billowing clouds of steam. The intense heat solidified the magma, forming black, rocky terrain on the water's surface. Standing on it, Akainu's imposing figure exuded menace.

"Such terrifying killing intent—worthy of a Marine Admiral indeed," Ron said, gazing down at Akainu with a faint smile.

"But I'm afraid it's not enough to intimidate me."

Still floating above the sea, Ron crossed his arms and continued, "I could have avoided confronting you altogether. But since the World Government and Marines insist on delivering me such a grand gift—forcing someone like me, who had no intention of opposing you, to become your enemy—then I must return the favor properly."

His calm words carried an undercurrent of menace.

Suddenly, the six massive warships suspended in the air began to tilt downward.

Shouts of terror erupted from the Marines onboard as they plummeted into the sea like dumplings dropped into boiling water.

But Ron wasn't finished.

As Akainu prepared to launch another attack, the six warships floated directly above his head under Ron's control.

With a flick of Ron's wrist, the levitation ceased. The massive vessels, now subjected to gravity once more, hurtled down toward Akainu.

Akainu's expression remained cold, showing no regard for the Marines still clinging to the falling ships. Raising his magma-covered fist, he unleashed another devastating attack.

"Great Eruption!"

The volcanic punch shot upward, obliterating the descending warships in an instant. The impact caused the molten fragments to rain down like fiery meteors.

Fortunately, Garp, Hina, and other Marine officers acted swiftly, rescuing the remaining soldiers still aboard the warships just moments before they were caught in the fiery inferno.

With a thunderous explosion, Akainu's magma punch continued its trajectory, surging toward Ron like an erupting volcano. Its sheer scale and power were overwhelming.

Hovering in midair, Ron squinted slightly at the approaching magma fist. With a calm yet decisive motion, he drew his blade—Shusui.

…

"Sun Breathing, Full Concentration!"

…

The air around Ron shifted, his body exuding an aura of absolute focus and power.

With a sharp metallic sound, his blade became encased in the jet-black hue of Armament Haki. The terrifying power of the Float-Float Fruit extended along the edge of the sword, amplifying its strength even further.

Ron raised the blade high, his eyes burning with an unyielding resolve, ready to face the volcanic force head-on.

Ron, who had achieved the realm of a Great Swordsman, unleashed a devastating slash toward the terrifying attack coming from below.

"Purgatory!"

In that instant, under the stunned gazes of everyone present, a slash imbued with black flames erupted from his blade. The sword energy extended for thousands of meters, carrying the power to seemingly cleave the sea in two, and descended from the sky with unstoppable force.

The moment it collided with Akainu's volcanic magma fist, which resembled a volcanic eruption, a blinding explosion of fiery light burst forth. It was as brilliant as the sun itself.

A searing shockwave rippled out in all directions, carrying with it unbearable heat.

Within a radius of a thousand meters, the sea boiled violently. The surface bubbled and frothed, sending clouds of steam skyward. Countless fish surfaced belly-up, their lifeless forms scattered across the water.

Even a thousand meters away, on the Heart Pirates' ship, the shockwave swept through, igniting fabric and wooden planks on board.

Yet, Law, Bepo, and the other crew members hardly noticed the flames around them. Beads of sweat rolled down their foreheads as they stood frozen, their expressions filled with awe and disbelief as they gazed toward the distant battlefield.

At the heart of the chaos, the sea was in utter turmoil.

A massive crack several thousand meters long and dozens of meters deep split the ocean apart, and the water had yet to recover from the devastating blow. Black flames, burning with unrelenting fury, dotted the surface, refusing to be extinguished.

The sea surged wildly, as torrents of water rushed into the enormous chasm, creating towering waves that seemed to scrape the sky.

Above, in the sky, fragments of molten volcanic debris rained down like meteorites. They crashed heavily into the tumultuous sea, adding to the apocalyptic scene.

The landscape had transformed into an infernal purgatory—a world on fire, where the sea itself seemed to boil under the wrath of gods.
