One Piece: With Sign-in System

On the remnants of the severed Drum Mountain, the battle between Ron and Kizaru grew fiercer.

Ron unleashed the powers of the Float-Float Fruit, wielding the other swords—each bathed in a deep purple-black aura from his Haki. These blades moved with incredible speed, creating a crisscrossing storm of sword light and slashes. The resulting sword formation covered both combatants, trapping Kizaru and preventing him from utilizing his incredible speed by turning into photons and darting across the battlefield.

Kizaru raised his hand, firing beams of concentrated destructive energy at Ron. The searing blasts packed immense penetrating force but were relatively simple to evade.

Meanwhile, Ron used his Float-Float Fruit to summon a raging blizzard. The violent snowstorm condensed into massive ice dragons that roared toward Kizaru. Yet, they too were split apart by Kizaru's hand-held Light Sword, the Ama no Murakumo, forged entirely of photons.

The constant clash of abilities and sword strikes gradually chipped away at the remaining half of Drum Mountain, leaving it reduced layer by layer, like a sandcastle meeting the tides.

…

On the other side of the battlefield, the skirmishes were no less intense.

Enzo and Robin, having dispatched the elite Marines, were now focused on overpowering Vice Admiral Doberman.

Although Doberman's full-body Armament Haki allowed him to block most of their attacks, the unrelenting pressure from the duo's coordinated strikes left him unable to counterattack effectively. To make matters worse, he was forced to stay wary of the pink-haired young woman whose peculiar ability posed a grave threat.

…

Clang!

A fierce clash erupted as Kuina's dual blades met the eight swords of Vice Admiral Onigumo. The air between them crackled with crossing slashes, their sword energies intersecting in dazzling arcs.

The ground beneath them, unable to withstand their collision, cracked and fractured into a web of destruction.

After a ferocious exchange, both fighters withdrew, creating a distance of over thirty meters between them.

Onigumo's helmet had been shattered, revealing his fierce and grim face, now marred with several slash wounds across his chest. Kuina's shoulder and hand were bleeding, her grip on her sword slightly weakened.

Was it a stalemate?

No. Judging by the trembling in Kuina's arms, it was clear she was at a slight disadvantage.

"Come on! Let's go again!"

Onigumo, his battle spirit ignited, roared as he prepared to attack once more.

Kuina glanced at Conis, who was holding her ground in another skirmish.

It's almost time…

Taking a deep breath, Kuina let her dual blades return to their sheathes.

"Huff…"

She exhaled sharply, placing her hand on the hilt of Wado Ichimonji at her waist. Her body shifted into a low, poised stance. Her entire presence, as well as her rampant sword energy, began to recede inward, focusing entirely on the blade. Around her, faint golden lightning began crackling, sparking ominously.

A sense of impending danger gripped Onigumo.

Yet, instead of fear, his expression twisted into exhilaration.

"So, you want to settle this in one move… Very interesting!"

He mimicked her preparation, his eight swords now encased in Armament Haki, glowing black with raw power. His wild and aggressive sword energy erupted outward, clashing violently against Kuina's calm and collected pressure.

One gathered energy inward; the other unleashed it outward.

The stark contrast in their styles created a heavy, suffocating tension in the air.

A gust of wind swept through the battlefield.

Onigumo stomped his foot, shattering the ground beneath him. With his eight swords raised, he leaped forward, the combined force of his attack forming a giant black spider-shaped shadow of death as he charged at Kuina.

"Eight-Spider… Death Slash!"

As he advanced, the very ground beneath him was shredded apart by his sword energy, the air itself howling in agony.

"Thunder Breathing, First Form - Thunderclap!"

Kuina's voice was steady yet electrifying as she whispered the words. She closed her eyes, channeling her focus. A golden lightning aura exploded around her, engulfing her in radiant thunder as she kicked off the ground.

The battlefield quaked under her step.

The earth beneath her crumbled, then shattered entirely, leaving a spiderweb of cracks that radiated outward in a deafening boom.

Her form blurred—no, vanished.

Only the roar of thunder remained.

In an instant, the battlefield was lit by the blinding golden light of Kuina's attack. A split-second later, a deafening shockwave tore through the area, leaving the earth scorched and shredded.

What followed was silence.

The massive spider-like shadow formed by Onigumo's attack dissipated. Onigumo himself stood frozen in place, his eyes wide with disbelief. His swords shattered into fragments, scattering around him.

A thin, clean line of golden light sliced through his chest, and then—

Thud!

Onigumo crumpled to the ground, defeated.

Kuina stood behind him, her back turned, sheathing Wado Ichimonji with a resonant click. The golden lightning crackling around her faded as she exhaled a steady breath, calm and victorious.

She looked over her shoulder, her eyes sharp and focused.

"It's over."

The tide of the battle had shifted.

…

Far above, on the decimated remains of Drum Mountain, the clash between Ron and Kizaru was reaching its crescendo.

Kizaru raised his leg once more, preparing another devastating light-speed kick. "You ever been kicked at the speed of light?" he teased again with his usual lazy drawl.

Ron, gripping his black blade Shusui tightly, simply smirked.

The final act of their battle was about to begin, and the whole world watched, holding its breath.

A streak of golden lightning flashed through the air, slicing through the massive black spider.

…

Kuina appeared at the spot where Onigumo had previously stood. Slowly, she unsheathed her sword, the Wado Ichimonji, now radiating with Haki-infused energy.

"Thunderbolt Slash."

A pinnacle of Iaijutsu, focusing all energy to a single point in an instant.

Shing!

Onigumo's eyes lost focus, and in the shocked, wide-eyed gazes of countless spectators watching the live feed, he collapsed to the ground.

The vice-captain of the Calamity from the skies, Kuina, the sword maiden—her name resonated across the seas with this decisive strike.

"Did you see that? What an incredible Iaijutsu technique! I can't believe such power exists in that slender frame!"

"It was like watching a golden lightning bolt!"

"A Marine Vice Admiral... defeated?!"

"She's terrifyingly strong!"

"What's next? Could the Marines actually lose this battle?"

"Don't talk nonsense! The Marines can't lose to criminals!"

"Don't be so sure. These guys aren't your average criminals…"

Just as the audience was recovering from the shock of Kuina's triumph, an unexpected and shocking event unfolded.

A colossal figure appeared beside Kuina as though teleporting. Without hesitation, a massive paw descended toward her.

Though Kuina noticed the attack, her body was too drained from delivering that ultimate slash to evade. Her eyes widened as the paw came down.

Whoosh!

Kuina vanished into thin air.

The sudden turn of events left every viewer slack-jawed and frozen, staring at the screen.

"It's... it's the Tyrant Kuma! One of the Seven Warlords of the Sea!"

"He's finally made a move?"

"She vanished in one strike… is she dead?"

"No way… that can't be true…"

Meanwhile, on the other side of the battlefield, Robin and her allies were still engaged in a fierce fight with Dalmatian. They hadn't noticed what had transpired with Kuina.

"Six Flowers: Spider Net!"

Robin activated her powers, conjuring countless arms in midair. The limbs wove together like a web, entangling Dalmatian and pinning him in place.

"Eight-Impact Fist: Triple Void Strike!"

Enzo leapt into the air, his Haki-infused fists delivering a barrage of devastating blows to Dalmatian's abdomen. Each strike unleashed a shockwave of concentrated power.

"Argh!"

Doberman coughed up bile, his face contorted in pain as he fell to the ground with a thud.

"Iron Bind!"

Conis extended her hands, summoning chains that slithered through the air like serpents, wrapping tightly around Dalmatian's limbs and securing him firmly to the ground.

"Bonnie, now's your chance!" Robin called out urgently.

"On it!"

The young woman with pink hair and a determined gaze sprinted toward the restrained Marine, her hands glowing as she prepared to unleash her ability.

Doberman gritted his teeth, struggling futilely against the chains and Robin's grasping arms as Bonnie closed in.

"Damn it!"

But just as Bonnie's hand was about to make contact, an enormous shadow loomed over her.

In a fraction of a second, Bartholomew Kuma appeared before her, his expression cold and indifferent.

Bonnie's eyes widened in shock as Kuma raised his paw.

Whoosh!

In the blink of an eye, Bonnie disappeared.

Robin, Conis, and Enzo stood frozen, their eyes wide with disbelief.

"This… can't be happening!"

"Damn it!"

Enzo roared in fury, snapping out of his stupor. He used Shave to appear in front of Kuma, his fist coated in Haki and blazing with heat, punching toward the warlord.

Kuma raised his paw and caught Enzo's attack effortlessly, nullifying the shockwaves and force of the strike.

"Pressure Cannon," Kuma said in a low voice.

A powerful shockwave erupted from his paw, sending Enzo hurtling backward like a cannonball.

Whoosh!

Nine spinning iron spikes flew toward Kuma from different angles, tearing through the air.

Kuma casually raised his paw again.

The air itself rippled violently, and with a resounding shockwave, a barrier of pure force radiated outward from Kuma, deflecting the incoming projectiles effortlessly.

The battlefield fell silent for a moment, the overwhelming presence of Bartholomew Kuma casting a shadow over the Crew.

Conis gritted her teeth and pushed her abilities to their limits.

But the gap in strength was insurmountable.

No matter how hard she tried to drive her powers, the iron spikes she controlled were utterly incapable of piercing through the barrier formed by the waves of shock.

Bartholomew Kuma moved his other paw, slapping it against his own body, and in an instant, he appeared directly in front of Conis.

Her widened eyes reflected the massive paw that rapidly grew closer.

Swish!

The Steel Witch, Conis, vanished in the same manner, leaving the audience before their screens frozen in shock.

Kuma took a slow step forward, now standing before Nico Robin. His towering frame and emotionless expression cast a heavy shadow over her.

Robin's gaze trembled slightly.

So this is the strength of Bartholomew Kuma—the Tyrant, a member of the Seven Warlords of the Sea, alongside Crocodile?

The sheer oppressive force was overwhelming!

It was a league far beyond that of a Vice Admiral!

Robin bit her lip hard, preparing herself for one final, desperate struggle.

But just as she was about to unleash her powers...

Swish!

A streak of black shot through the air from the distance, heading straight for Kuma with unstoppable momentum.

It was none other than Enzo, the Kung-Fu Dugong, launching himself like a missile.

His round head, hardened to an obsidian black by Armament Haki, was his greatest weapon—an unyielding force of nature.

Faced with this powerful attack, Kuma showed no fear. He simply raised his paw to meet the strike.

Boom!

The two forces collided in a thunderous explosion of compressed air.

The ground beneath them shattered instantly, sending debris flying. A fierce gale swept through the battlefield, shaking even the distant reporters and cameras, causing the live footage to blur and stutter.

When the dust finally settled and the image cleared...

The battlefield, now a devastated wasteland, showed only one figure standing—Bartholomew Kuma.

The ferocious Kung-Fu Dugong, along with Nico Robin, had vanished without a trace.

The audience watching from their screens around the world were left in stunned silence.

And then, breaking through the tension, a new figure descended from above!

Boom!

The impact sent tremors across the battlefield as the figure landed heavily in the center.

The already shattered ground caved further, sending a storm of debris and dust into the air.

Under the watchful eyes of countless spectators across the globe...

From the deep crater at the heart of the battlefield, a young man emerged. His black hair danced wildly in the air, his entire body emitting a red, steam-like aura. A streak of blood marked the corner of Ron's sharp, cold eyes. In his hand, he held a gleaming black blade.

As the Marine Admiral Kizaru descended from the sky, his Justice coat billowing behind him...

As Vice Admiral Doberman, now fully coated in Armament Haki, broke free from his steel bindings and stood upright once again...

And as Bartholomew Kuma, unmoving and unyielding, loomed at the forefront...

The three formidable figures formed a triangle around the black-haired swordsman.

The world seemed to hold its breath.

Countless spectators watching the scene unfold on their screens swallowed hard, cold sweat dripping from their foreheads.

"This… This is insane!"

"How could anyone escape from a situation like this?!"

"This is a lineup meant for a Yonko! Isn't this too much?"

"The sheer pressure of just watching this… I feel like I can't breathe."

"This is utterly hopeless…"

"The legend of Ron, the Wanderer… Is it truly going to end here?"
