One Piece: With Sign-in System

Dressed in a black coat and wearing a black top hat, Ron strolled leisurely through the bustling streets, moving with an air of ease and refinement.

His demeanor was more aristocratic than that of the actual nobles residing on the island.

As he passed through the streets, many women couldn't help but turn their heads to glance at him—only to catch a fleeting glimpse of his departing figure.

Ron's eyes remained shut, blind to the world.

Yet, his Observation Haki, fused with his Transparent World, formed a unique domain that enveloped the entire island, feeding every intricate detail back to him.

At this very moment, he could clearly perceive the presence of two familiar figures just two streets away—their auras, conversations, scents, and even their emotions.

Hearing the words spoken by one of them—Gion—Ron's lips curled into a subtle smirk.

"So, they've caught wind of the rumors, huh? No wonder this all feels so coincidental."

With that, he changed direction, walking straight toward where Hina and Gion were.

As he walked, Ron spoke inwardly, directing his thoughts to the system.

"System, how many days until the seal on my eyes is lifted?"

A mechanical voice echoed in his mind.

[Host, at the current progress, the seal will be lifted in 34 days.]

"Thirty-four days, huh..."

Ron nodded slightly, deep in thought.

With a single mental command, a translucent screen appeared in his consciousness, displaying his current attributes—

If two years ago, his Ultimate Kick had only managed to seriously wound Kaido, leaving him just shy of Admiral and Yonko-level strength, placing him at the Quasi-Emperor tier—

Then now, two years later—

With both Observation Haki and Armament Haki breaking through their bottlenecks to the Third Stage, and his swordsmanship reaching new heights, Ron had undeniably stepped into the realm of Yonko-level power!

If he were to face Admiral Kizaru again—

This time, Kizaru would be the one running away.

Furthermore, his Float Float fruit was approaching the threshold of Awakening, and once he shattered that final barrier, combined with the eventual unsealing of his Tenseigan—

His strength would skyrocket once more, truly surpassing the Yonko and reaching the pinnacle of this world's power structure—

A realm beyond the Yonko!

…

As Ron stepped onto the street, he immediately sensed the presence of Hina and Gion—they were inside a café, roughly a hundred meters ahead of him.

Just then—

With his Observation Haki, Ron glimpsed a fragment of the future. His head turned slightly, looking toward the opposite side of the street.

A few seconds later—

Bang!

A loud explosion shattered the calm of the street. The heavy wooden doors of a building across from Ron suddenly burst open, sending shards flying. Pedestrians nearby jumped in fright, gasping at the unexpected commotion.

The crowd instinctively turned toward the source of the noise—

A burly man, wearing a metal slave collar, staggered out from the wrecked doorway. His face was twisted in pure desperation, veins bulging in terror.

"Help! Help me!!"

His voice was hoarse, filled with sheer panic.

He stumbled forward and grabbed the nearest passerby—his trembling hands clutching the man's shoulders in a desperate plea.

The unlucky man he had seized was frozen in terror, his eyes wide with fear.

Tears and snot streamed down the burly man's face as he clutched his slave collar, his expression utterly hopeless.

"Please... help me take this off... I'm begging you! I don't want to die!!"

The man he held was too frightened to speak, his entire body shaking uncontrollably.

…

Inside the café.

Hina, who had been calmly sipping her coffee, stood up with a frown.

"Wait a second."

Gion raised an eyebrow. "What is it?"

Holding her coffee cup, Gion gazed in the direction of the commotion and spoke in a low voice.

"That collar... It bears the Celestial Dragons' insignia. That man is a slave of the Celestial Dragons."

Hina's pupils shrank slightly.

"A runaway slave...?" she murmured.

Gion sighed, her expression complicated. "We, as Marines, are in no position to intervene."

Hina clenched her fists tightly, her knuckles turning white.

…

On the street, the beeping sound of the slave collar suddenly intensified.

The moment the sound changed, the crowd's faces paled in horror—

"It's going to explode!"

"RUN!"

Panic erupted. The surrounding people bolted in all directions, their faces filled with terror.

The man caught in the burly slave's grip struggled violently, trying to break free—

But no matter how hard he fought, the slave's grip was unyielding.

"Hahaha..."

The burly man laughed, but it was a chilling sound—filled with utter despair.

His face twisted into a grotesque mask of hopelessness and madness as he stared at the terrified man in his grasp.

"I did nothing wrong..." His voice trembled with rage and grief.

"And yet, my companions were slaughtered like dogs!"

His bloodshot eyes burned with fury.

"I can never go home again... so why should I be the only one to suffer? If I have to die... then you're coming with me!!"

"NO! PLEASE! HELP! SOMEONE HELP ME!!"

The man screamed, struggling with all his might, but he was trapped in an inescapable fate.

The beeping grew louder, an ominous countdown to death.

The surrounding bystanders stood tens of meters away, watching with expressions of dread and helplessness.

At the very last second—

Just as the countdown reached zero—

A slender figure flashed between the two men.

BAM!

With a swift and precise kick, the burly man was sent flying through the air.

And then—

BOOM!

The slave collar exploded mid-air. The deafening blast shook the entire street, and the force instantly incinerated the man's body.

The bystander who had been held captive collapsed onto the ground, his entire body trembling violently.

He gasped for breath, drenched in cold sweat, as if he had just crawled back from the depths of hell.

Hina, still standing at the café's entrance, stared grimly at the charred corpse falling from the sky.

"Ara~ It's already over? How dull."

A haughty, feminine voice rang out from the distance.

The instant that voice echoed through the streets—

Every single person froze.

And then—

As if by instinct, the entire street fell into silence.

All at once—

Everyone knelt.

Even the children were forced down, their parents pressing their heads to the ground.

Because they knew—

A Celestial Dragon had arrived.

…

Gion, now standing beside Hina, muttered, "Let's go."

Hina, her expression dark, nodded. Just as she was about to leave, something caught her eye.

Among the entire crowd bowing their heads to the ground—

There was one person who remained standing.

His back was straight, his posture unwavering—a lone figure defying the scene.

Hina instinctively took a few more glances at him.

And at that moment—

The man, dressed in black with a high-collared coat and a top hat, lifted his head—

His eyes met hers, and a faint smile appeared on his lips.

Hina's eyes widened in shock.

Beneath the shadow of the black brim—

That familiar face made her heart skip a beat.

"...Ron?!"

Her mind reeled. Why is he here?!

Gion, noticing Hina's stunned expression, frowned slightly.

"What's wrong?" she asked.

Hina didn't respond.

Instead, she remained frozen, staring blankly at the lone figure standing against the sea of kneeling people.

Curious, Gion turned her gaze in the same direction—

And in an instant—

Her sharp amber eyes locked onto the man standing tall at the back of the kneeling crowd.

Her fingers tightened around the hilt of her sword.

Because she recognized him immediately.

Her heart skipped a beat.

"It's him!"

She inhaled sharply.

He was really here... on this island?!

...

Just as the two women were still reeling from Ron's sudden appearance—

Not far away—

Saint Rozward and Saint Shalria, two World Nobles, were being carried on the back of a giant slave as they made their way toward the commotion.

"How many is this month?" Rozward asked casually.

"The fifth one, I think." Shalria's voice was laced with annoyance.

"You're really bad at training them."

"Hmph! Father, I put a lot of effort into training them, but these lowly humans are just too useless—so stupid and weak." Shalria crossed her arms and huffed in frustration. "I still prefer strong slaves. Next time, buy me some more giants, okay?"

As the terrified onlookers remained kneeling on the ground, trembling in fear, the two arrogant Celestial Dragons, along with their entourage of slaves and guards, arrived at the spot where the collar-wearing man had been blown apart.

Saint Shalria stepped down from her giant slave, her bubble-helmet reflecting the light as she scrunched her face in disgust. She lifted her foot and stomped down on the charred corpse with undisguised revulsion.

"Useless trash! A lowly human slave dared to try escaping from me?"

She ground her heel into the corpse.

"How… infuriating."

She pulled out a pistol and, without hesitation, fired several shots into the lifeless body.

Bang! Bang! Bang!

She swept her gaze over the kneeling crowd, her eyes filled with cruelty and disdain.

"A bunch of filthy lowly humans."

At that moment—

A faint cough broke the eerie silence.

A young boy, suffering from asthma, couldn't hold it in any longer despite his father pressing his head down against the ground.

The cough wasn't loud.

But in this dreadful moment of absolute silence, it was unbearably conspicuous.

The boy's father instantly turned ice-cold, his entire body drenched in fear.

Shalria's expression darkened. Her cruel eyes narrowed as she slowly raised the still-smoking pistol—pointing it toward the direction of the cough.

The father's face turned pale as death, and he stammered in panic, "No! That was just—"

The young boy, unaware of what was happening, blinked in confusion as he looked up—only to see the pistol aimed right at him.

Shalria smirked.

Her finger tightened on the trigger.

Bang!

The father instinctively shoved his son aside, but—

Bang!

Another gunshot echoed.

In an instant, a streak of silver light tore through the air.

With perfect precision, the bullet shattered Shalria's shot mid-air, reducing it to nothing. But it didn't stop there—the silver streak continued, piercing straight through Shalria's hand.

"AAAAHHH!!"

Her agonized screams filled the air.

The father and son, along with the crowd of kneeling civilians, were all left in stunned silence.

Their eyes slowly turned—

To the lone figure standing tall among them.

A man in a black coat.

A black hat.

In his hand, a silver revolver still smoking from the shot.

Shalria, clutching her bleeding hand, shrieked in rage and pain, "HOW DARE YOU—!!"

Saint Rozward, his face twisted with fury, pulled out his own pistol and fired.

Bang!

But before the bullet could even reach its target, the black-coated man casually tilted his head, dodging it effortlessly.

The Celestial Dragon's guards and slaves instantly sprang into action.

Bang! Bang!

Two more silver streaks flashed.

A massive giant slave—headshot.

A bodyguard, skilled in the Marine's Six Powers, attempted to use Shave to dodge, but the bullet moved impossibly fast.

"Iron Body!"

He hardened his muscles in a last-ditch effort to block the shot.

But—

The bullet, imbued with Armament Haki, pierced straight through his forehead.

Rozward took a terrified step backward, his hands trembling as he stared at the figure in black.

"Y-You… What do you think you're doing?! We are Celestial Dragons—"

Before he could finish his sentence—

Bang!

A silver bullet streaked toward his skull.

At the very last moment—

"Tempest Kick!"

A sharp, crescent-shaped blade of wind shot out from the side, intercepting the Haki-infused silver bullet mid-air.

The man wielding the silver revolver turned slightly, his gaze landing on the approaching figure—a woman in civilian clothing, her sharp eyes carrying a calm yet firm resolve.

Gion smiled faintly as she lowered her leg.

"Gion… are you here to stop me?"

Her gaze locked onto Ron. "Ron, that's enough. Killing a Celestial Dragon isn't something to take lightly."

The already-shocked onlookers felt their minds go blank at her words.

"Ron…"

"Could it be…?"

Among the crowd, several pirates and reporters suddenly widened their eyes in realization.

When Gion called out his name, they instinctively looked beneath the brim of his black hat—and in an instant, recognition dawned.

"It's him… Is he really that Ron?!"

"The Traveler Ron?!"

"No wonder… no wonder he dared to attack a Celestial Dragon!"

Someone trembled with excitement. "If it's him, then he really might kill a Celestial Dragon!"

"Wait, isn't that Marine Headquarters' Gion?"

The identities of Gion and Hina were also quickly recognized by the more informed spectators.

Hina stood not far away, her expression conflicted as she watched the confrontation between Ron and Gion.

By the strict code of the Marines, Ron was undeniably an enemy—after all, he had just attacked a Celestial Dragon.

And yet…

After witnessing what had happened firsthand, Hina found it difficult to take action on behalf of these cruel, depraved so-called World Nobles.

Gion, however, had no such hesitation. As a Marine, she had made her decision. She would act.

Even if her opponent was him.

"D-Damn it! He really tried to kill me! That filthy lowly human!"

Saint Rozward, now saved by Gion's intervention, was trembling with rage. His face twisted with hatred and fear.

"You! Woman! You're a Marine, aren't you? Arrest that man immediately! I want him executed!"

Gion remained with her back to him, but for a fleeting moment, an expression of helplessness flashed in her eyes.

If given the choice, she would have preferred not to defend this kind of so-called World Noble.

Under the watchful eyes of the stunned crowd, Ron slowly reached up and removed his black hat, revealing a face that was both calm and strikingly handsome.

Behind him, the father and son he had saved stared up at him in utter awe, as if looking at a deity who had descended upon the mortal realm.

"Gion… step aside. You can't stop me."

Ron stepped forward.

A precise, controlled wave of Conqueror's Haki surged outward from him.

The Marines who had arrived as reinforcements—along with the Celestial Dragons' personal guards—barely had time to react before their eyes rolled back, and one by one, they collapsed unconscious to the ground.

The entire battlefield fell eerily silent.

"W-What just happened?!"

"Wh-What did he do?!"

Many civilians were clueless about what had just transpired.

But among the crowd, several veteran pirates—those with bounties reaching tens of millions, even over a hundred million—had already broken into cold sweats. Their faces paled as they stared at Ron's figure in horror.

"That was Conqueror's Haki…?!"

"And with such precise control… Incredible!"

"No wonder they say he's on par with the Four Emperors… What a terrifying man!"

"What will happen next…?"

Several journalists, faces drenched in sweat, hurriedly raised their cameras to capture the unfolding spectacle.

All eyes turned toward the battlefield once more.

Gion remained still, her gaze locked onto Ron as he approached her.

She sighed.

"You're right. I can't stop you."

"But Ron, if you do kill a Celestial Dragon, the Admirals will come. Not just one—maybe even two. Even if you escape, your companions… they're still on this island, aren't they? Will they be safe?"

The Marines had only just managed to stabilize the current state of affairs, and Gion genuinely didn't want Ron to shatter that fragile balance with yet another catastrophe.

She didn't want to become his enemy.

Ron barely reacted to her words.

"The only reason those trash Celestial Dragons have survived this long is because of the Marines."

"If the Admirals want to come, let them come. One, two—it doesn't matter. I'll be right here waiting for them."

His voice was calm, unwavering.

Ron stepped forward once more.

He came to a stop before the kneeling figure of Saint Shalria.

Her right hand—now riddled with a bloody, gaping hole—trembled as she glared at him with eyes full of hatred and venom.

"You filthy lowly—!"

Before she could finish—

Ron's expression remained indifferent as he stepped down.

With his current strength, a single stomp carried enough force to crush a small hill.

There was no doubt about what would happen when such power landed on an ordinary human.

In an instant—her leg was completely shattered!

A gruesome explosion of flesh and bone splattered across the ground.

"AHHHH!!!"

A shriek of agony tore through the air, piercing enough to make one's blood run cold.

The crowd stood frozen, their faces blank with disbelief, staring at the scene in sheer shock.

"You! You actually dare…! Damn it! Marine woman, why haven't you acted yet?!"

Saint Rosward trembled violently, his face contorted with both terror and rage.

He couldn't comprehend it—couldn't process that someone had truly dared to lay hands on a Celestial Dragon!

But Gion ignored him entirely.

Instead, her gaze remained locked onto Ron, a single bead of cold sweat rolling down her cheek.

This was bad.

That killing intent…

Ron was serious.

Before anyone could react, Ron lifted his foot once more and, under countless stunned gazes, brought it down again.

A sickening crack!

The other leg exploded into a mangled mess of blood and pulverized bone.

"AAAAHHHH!!!"

Saint Shalria's mouth hung open in a silent scream, her face contorted into a grotesque mask of pain.

Her lower body had become nothing more than a gruesome pulp of shattered limbs and torn flesh. Every nerve in her body was aflame with unimaginable agony.

She was still alive.

Still conscious.

And that was the worst part of all.

Watching Ron raise his foot again, Gion could no longer stand by and do nothing. She couldn't allow him to simply stomp a Celestial Dragon to death right in front of her.

As a Marine, she had to act.

In a blur, she used Shave to close the distance, her long right leg sweeping forward in a powerful kick—hardened with Armament Haki.

Though she was known as a great swordswoman, her mastery of the Six Powers was on par with those Marine Vice Admirals who specialized in them.

But the moment her kick was about to connect—

Ron vanished.

He disappeared the very instant before impact, reappearing back in the same spot just as her attack sliced through his afterimage.

To the naked eye, it was as if her kick had phased straight through a ghost.

And his foot never stopped descending.

Another crunch.

Another limb—gone.

Shalria's right arm exploded into a mess of ruined flesh and bone.

At this point, her body had reached its limit—her voice was hoarse, unable to even scream anymore.

But Ron wasn't finished.

He lifted his foot once more.

Her final arm was crushed into an unrecognizable mass of flesh.

Everyone stared, utterly stunned, as the high and mighty Saint Shalria—once so arrogant, once so untouchable—lay in the dirt, mutilated beyond recognition.

It was then that something clicked in their minds.

Without the status of a Celestial Dragon, without the privilege and power they wielded…

They were nothing more than ordinary humans.

And ordinary humans…

Could die just like anyone else.

Gion launched another attack, but Ron evaded it with ease.

Then, hovering in midair, he calmly raised his silver revolver.

The polished barrel gleamed under the light.

The crowd could only watch in stunned horror as he aimed it downward—

And pulled the trigger.

BOOM!

A single bullet, wreathed in Haki, shattered Shalria's skull in an instant.

She was dead.

The shot had been clean, precise—brutal in its simplicity.

The moment was captured perfectly.

The journalists on the scene had filmed everything.

Gion stood frozen in place, her eyes locked onto Ron as a deep, conflicted look crossed her face.

So, in the end…

He still did it.

"He… He killed a Celestial Dragon!"

"A Marine Admiral will come for sure!"

"This is insane!"

"What kind of monster is he?! Traveler Ron…!"

"He's the one who defied even the Emperors! A man so insane that not even the Four Emperors can compare to his madness!"

"The God-Slayer!"

After the initial shock wore off, chaos erupted.

Some trembled in fear.

Some were filled with awe.

Some screamed in panic.

Some… laughed in wild exhilaration.

And amidst it all, a certain journalist gripped their camera with trembling hands.

Staring at the image captured within, they couldn't help but murmur:

"This world… is about to change."
