One Piece: With Sign-in System

"Are you here to capture me?" Ron asked, his gaze fixed on Kuma.

Kuma nodded, his expression calm. "It's not just me. Admiral Kizaru is also on his way."

Ron narrowed his eyes.

Kuma mentioned only Kizaru, as if implying that the admiral was the sole threat worth noting. The two vice admirals accompanying them didn't even warrant a mention; in Kuma's eyes, they posed no significant danger to Ron.

"In the middle of the battle, I'll find an opportunity to send you all away," Kuma said, his voice steady. "If you're going on a journey, where would you like to go?"

Before Ron could respond, a yellow flash flickered on the horizon above the distant sea.

Both Ron and Kuma sensed Admiral Kizaru's arrival at almost the same time. Kuma raised his massive paw, directing it toward Ron and his group.

"Pressure Cannon."

A paw-shaped shockwave shot toward them with incredible speed.

Ron instantly utilized Shave to evade the attack. The shockwave struck the ground where he had been standing, creating a massive paw-shaped crater over ten meters wide. The earth fractured and sank under the immense force.

Above the battlefield, golden photons coalesced into the form of Admiral Kizaru. Hands tucked into his pockets, he exuded his signature air of laziness and nonchalance.

"Already started fighting, huh? As expected, you're quite fast, Kuma," Kizaru remarked.

As he appeared, Kuina, with her blue hair tied in a high ponytail, instinctively reached for the hilt of her sword. Her aura shifted, gathering into a sharp, focused energy that promised an explosive strike at any moment.

Conis, meanwhile, activated her ability. Countless iron spikes materialized around her, spinning and glinting with deadly precision as they hovered protectively in her orbit, their tips aimed at Kizaru.

Even Enzo adopted a fighting stance. Spiraling energy coiled around his small fists, poised for an attack.

"Oh?" Kizaru's eyes gleamed with faint interest.

These three... All of them had mastered Observation Haki?

A moment later, Bonney and Robin, though slightly slower to react, also shifted into combat stances. Their gazes locked onto Kizaru, ready to unleash their respective abilities.

Having dodged Kuma's initial attack, Ron returned to stand protectively in front of his companions, his demeanor calm.

"Seeing me doesn't seem to surprise you much," Kizaru said, his gaze lazily drifting over Ron.

"I expected it," Ron replied with a faint smile. "But I'll admit, your speed is faster than I anticipated."

"When dealing with someone like you, how could we not move quickly?" Kizaru remarked as he vanished in a blur of light.

In an instant, Kizaru reappeared right before Ron, his glowing right leg raised high. "Have you ever been kicked at the speed of light?"

"Never."

With the aid of Observation Haki, Ron predicted Kizaru's movements. He lifted his own leg, encased in Armament Haki, to counter the incoming attack.

The moment their Haki-infused legs collided, a devastating shockwave erupted, radiating outward like a violent storm.

The ground beneath them quaked and caved, fissures spreading in every direction.

The air roared with a deafening boom as fierce winds tore through the surroundings.

The thick snow blanketing the area was blown away entirely, trees splintered and toppled, and the earth itself seemed to recoil.

From where Ron and Kizaru stood, an expansive, spherical void formed amidst the falling snow—a space completely devoid of any snowflakes within a radius of a hundred meters.

Kizaru, still with his hands casually in his pockets, peered down at Ron, who had matched his Flash Kick with ease. A sly smile crept across his face.

"So, this is your current strength? Terrifying, as expected," Kizaru drawled.

Ron's dark hair whipped in the wind as he looked up with a harmless yet defiant grin.

"Enough talk. If you're going to fight, fight. Don't waste my time with nonsense."

"Such a scary young man," Kizaru quipped, his body transforming back into photons as he teleported away.

Ron disappeared from his spot as well.

The battle between Ron and Kizaru commenced with blinding speed. Even Kuina, the strongest among Ron's crew, found herself unable to keep up. The combatants moved too quickly for the naked eye to follow. Without Observation Haki, it was impossible to pinpoint their exact locations.

For those observing, the battle was a chaotic blur. Ron and Kizaru's forms appeared and vanished across the battlefield in rapid succession.

Every clash of their attacks unleashed thunderous booms that echoed across Drum Island, shaking the very ground beneath their feet.

"What's happening?"

The residents of Drum Island emerged from their homes, gazing in bewilderment at the tumultuous skies.

The townspeople gathered on the streets, staring at the distant mountains where flashes of yellow and black light illuminated the horizon.

The ground trembled violently as if an earthquake had struck.

Under the astonished gazes of the people, an entire swath of the forest in the distance seemed to erupt in an explosion, leaving behind a massive crater where once stood an untouched landscape.

"Is this... divine punishment?" one villager murmured, his voice trembling with fear.

The sheer ferocity of the battle caused avalanches to cascade across Drum Island. The local animals, including the carnivorous Lapahns, scattered in panic, turning the island into utter chaos.

Inside a hollowed-out tree cabin, where Dr. Kureha and Chopper resided, the ground shook violently once again.

Dr. Kureha, unable to contain her frustration, stormed outside.

"What the hell is going on out here?!" she demanded, her voice cutting through the howling wind.

Curious, Chopper followed Dr. Kureha outside.

Just as the two stepped out—

Zap!

A yellow laser shot diagonally from the sky, crashing into a nearby forest. The resulting explosion sent shockwaves rippling across the area. Before they could react, Dr. Kureha and Chopper were both blown off their feet and hurled back into the wooden house through the open door.

"Ouch, ouch, ouch!"

Dr. Kureha rubbed her head as she scrambled to her feet.

Chopper, upside down with his legs kicking in the air, looked utterly dumbfounded.

The two quickly steadied themselves and peeked cautiously outside.

The sight before them made Chopper's eyes nearly pop out of his head.

"Huh?! What is this?!"

Even Dr. Kureha, despite her hundred years of life experience, broke into a cold sweat.

The once-verdant forest had been completely obliterated by the blast, leaving behind a massive crater with jagged edges radiating outward.

"What on earth... happened here?" Dr. Kureha muttered in disbelief.

"Doctor... look! At the edge of the crater!" Chopper's voice trembled as he pointed a hoof toward the sky.

Dr. Kureha followed his gaze, her pupils shrinking as they landed on a figure hovering above the crater, his Justice cloak billowing in the wind.

"That... that's a Marine Admiral?!"

Before she could process the gravity of what she was seeing—

Whoosh!

A crescent-shaped black slash erupted from the depths of the crater, slicing toward the Admiral in the sky.

Kizaru raised a hand, forming a sword of light. Holding it with both hands, he swung downward, effortlessly blocking the mighty attack.

Dr. Kureha and Chopper stared in shock as a black-haired youth wielding a black blade slowly ascended from the depths of the crater.

Dr. Kureha's mind reeled.

"Could it be... him?!"

…

Ron and Kizaru, having tested each other with kicks earlier, now engaged in a fierce exchange of swordplay.

The moment Ron's black blade clashed with Kizaru's light sword, a black wave of energy erupted, carving through everything in its path.

A golden slash shot skyward, tearing through the clouds and leaving a scar in the sky that stretched for several kilometers.

As Ron and Kizaru's intense battle unfolded, Vice Admirals Doberman and Onigumo arrived on the island, leading a battalion of Marines armed with swords and guns.

Onigumo immediately engaged Kuina, while Conis and Enzo joined forces against Doberman.

Robin and Bonney, meanwhile, tackled the onslaught of Marines encircling them.

Standing a short distance away from the chaotic battlefield, Kuma watched silently, his gaze fixed on the fierce clash between Ron and Kizaru.

…

Out at sea, near Drum Island, ships of pirates, journalists, and adventurers converged upon the area.

Many pirate ships stopped in their tracks when they spotted the Marine warship docked at the shore. None of them dared to get too close, unwilling to attract the attention of an Admiral. Observing from a safe distance was enough for them.

On the other hand, journalists from the World Economy News Paper, under the command of their chief Morgans, were racing toward the island.

"Hurry! We need to broadcast this battle live!"

This was the kind of war the whole world would want to see.
