One Piece: With Sign-in System

Ron's black hair and bangs swayed gently across his forehead as he looked up, fixing his gaze intently on Doflamingo in front of him.

The opponent before him was definitely the strongest he had faced to date!

"I heard the Marines recently recruited a very young intern; that must be you, right, kid? What's your name again?" Doflamingo withdrew his leg and looked down at Ron with a slight smirk.

Ron said nothing. He only glanced around, noticing the Marines trainees around him being controlled by Doflamingo's strings. Swiftly, he swung his sword, slicing through each strand of thread, freeing the students from Doflamingo's control.

Doflamingo narrowed his eyes slightly, his gaze falling on the sword in Ron's hand.

"Kid, that's a pretty decent blade you have there. Mind if I take a look?" he sneered, extending his hand toward Ron.

Several thin, nearly invisible threads began weaving around Ron, as Doflamingo prepared to capture the surprisingly strong young man before him.

Being specially recruited by the Marines and personally trained by Zephyr, Ron possessed a rare and remarkable sword and skill. Such a talented youth would surely be highly valued by the Marines. If Doflamingo could capture him, he could use him as a bargaining chip to negotiate with them...

As the thought crossed his mind, a glint appeared in Doflamingo's eyes beneath his sunglasses, and his hand suddenly shot toward Ron with increased speed.

"Haki, harden!" Ron gripped the hilt of his sword with both hands, his gaze becoming razor-sharp.

Despite the formidable enemy in front of him, Ron's mind was incredibly calm, absorbing every sound and detail around him with absolute clarity.

Sun Breathing Technique, Full Focus!

Ron swung his sword, releasing a massive slash that resembled a burning tiger, fiercely surging toward Doflamingo's approaching hand. In an instant, all of the tiny, nearly invisible threads surrounding Ron were incinerated.

Doflamingo felt the power and Haki infused into this slash, his expression shifting subtly.

He realized his hand was about to be severed by the fiery strike.

Doflamingo's fingers extended into claws, channeling Armament Haki into them as he slashed forward.

"Five Color String!"

Five threads of various colors collided with Ron's giant flaming tiger slash.

They held in a deadlock for only a few seconds before Ron's slash was torn apart, and the Five Color Strings continued on their path toward Ron.

The difference in their current strength was evident.

But in Ron's eyes at that moment, the five threads slicing toward him appeared to slow down, revealing their details in his mind—the sharpness, resilience, speed, and the sheer killing intent and malice contained within each thread.

In that moment of heightened perception, Ron's eyes flickered with a faint glow.

He raised Raikiri in his hand, and crimson flames, like the scorching sun, slowly coiled up the hilt and spiraled along the blade.

Just as he was about to unleash this strike, a pitch-black iron fist shattered the Five Color Strings that were aimed at Ron.

Seizing the moment that Ron created by occupying Doflamingo, Zephyr used Soru to dash in front of Ron, neutralizing all the Marines trainees who had been immobilized by Doflamingo.

With his short purple hair and sunglasses removed, Zephyr stood covered in blood from numerous wounds, but his aura was intense, his gaze locked on Doflamingo with murderous intent, like a tiger poised to strike.

"Stand back, Ron. Leave the rest to me," Zephyr commanded, raising his pitch-black arms and positioning himself as a shield in front of Ron.

Ron looked at the injuries on Zephyr's back, wanting to say something, but Zephyr's voice was low and firm. "I'm not so old that I need the help of a kid like you. Get out of my way!"

With that, he stomped heavily, using his mastery of Soru, and instantly closed the distance to Doflamingo, launching a powerful punch.

The entire warship trembled.

Faced with this rage-fueled punch infused with Armament Haki, Doflamingo was sent flying from one end of the ship to the other, smashing through multiple layers of iron plates.

"Cough!"

A mouthful of bright red blood spurted from Doflamingo's mouth.

He looked up as a shadow loomed over him. Beneath his typically cocky sunglasses, Doflamingo's pupils contracted rapidly.

Boom!

Zephyr came crashing down from above with a powerful kick.

The warship dipped under the weight and tilted heavily, causing the surrounding seawater to churn.

Doflamingo barely avoided the strike, landing unsteadily on the swaying deck, blood dripping from his mouth, his gaze fixed on the slowly rising Zephyr.

"So this… is the strength of a Marine Admiral, the legendary Black Arm Zephyr. His reputation truly isn't undeserved."

Zephyr, his thick, muscular arms coated in Haki, said nothing, letting his killing intent and aura lock onto Doflamingo.

A bead of cold sweat rolled down Doflamingo's forehead.

"Heh heh heh… it seems I've managed to anger a fierce tiger today…"

The warship shook once more.

Zephyr vanished from where he stood.

Before Doflamingo could react, a kick struck him from the side, sending him flying again and breaking through the warship once more.

Just as he was about to plunge into the sea, Doflamingo gritted his teeth, using a thread to connect to the ship's railing, pulling himself back up to avoid falling into the ocean.

The moment he returned to the deck, Doflamingo unleashed his strongest attack.

"Overheat!"

In an instant, as he moved his ten fingers, countless razor-sharp white threads sliced out in all directions.

Zephyr appeared mid-air in front of him, his terrifyingly powerful, pitch-black fist poised to strike.

Doflamingo laughed with his usual arrogance.

"Fuffuffuffu… Zephyr, I'll let you choose—my life, or the lives of those students you care so much about."

Zephyr's pupils shrank, and with Observation Haki, he quickly sensed the situation nearby.

If he struck, he could kill this Heavenly Yaksha right here and now, but it was highly likely that the other trainees would be killed.

Without a second's hesitation, Zephyr made his choice.

He abandoned the idea of finishing Doflamingo and rushed back to save his students.

Watching this unfold, the heavily injured Doflamingo laughed even more wildly, filled with pride.

"Fuffuffuffu… Zephyr, even a powerful man like you gets entangled by such trivial emotions. Letting worthless weaklings become your weakness is downright pathetic."

On the deck, where Ron, Ain, and other surviving Marines stood.

Ron watched the razor-sharp white threads slicing toward them from all sides, sensing the danger within them. He tightened his grip on Raikiri, his Armament Haki hardening as it wrapped around his blade.

Doflamingo's all-out attack?

Even he wasn't confident he could fully counter it.

Ain was the first to act.

"Tempest Kick!"

However, her Tempest Kick failed to sever the threads and was instead shredded.

With a pale face, Ain gritted her teeth, standing before the other Marine recruits. She drew her sword, slashing at the white threads heading toward them.

"Azure Wolf!"

A burst of azure sword energy surged forward, but it was instantly sliced apart.

Ain's sword was also shattered into pieces.

Her eyes widened as the white threads grew larger in her pupils.

"Ain! Get out of the way!" Binz shouted urgently.

But Ain was too close to evade now.

At that moment—

"Breath of Wind, Third Form: Clear Storm Wind Tree!"

A fierce shout resounded from behind Ain.

Three powerful, green slashes surged forth with a violent gust of wind, colliding with the deadly white threads that were like scythes wielded by death.

The two forces held in a deadlock for an instant.

Just as the white threads started to slice through again—

A pair of massive, pitch-black fists, radiating a force powerful enough to shatter mountains, came crashing down.

In an instant, the white, razor-sharp threads were obliterated.

"Well done, Ron, my boy!"

Zephyr's towering figure appeared beside Ain.

"Master Zephyr!" Binz's eyes welled with tears.

Ain, having narrowly escaped death, fell to her knees, her legs giving way.

Ron, standing behind her, also let out a sigh of relief.

But in that moment, a chill crept up in his heart.

"Where is it?"

Ron turned, his vigilance heightened, scanning the surroundings.

A blood-tinted thread snaked out from the body of a deceased Marine recruit, silently springing to life like a serpent, darting toward the surviving Marines from behind.

If this attack landed, the Marine recruits would be skewered like fruit on a skewer.

Zephyr's pupils shrank as his Observation Haki sensed the insidious strike. His towering figure flashed, appearing behind the stunned Marine recruits just in time, though it was too late to mount a precise defense using Armament Haki.

Whoosh!

The nearly invisible, stealthy thread zipped through, carrying a trail of blood droplets as it pierced through Zephyr's right shoulder.

As it aimed toward the heart of one of the recruits, Zephyr's pitch-black hand grabbed it, stopping its deadly path.

"Fuffuffuffu!"

Doflamingo's arrogant laughter echoed from the warship's highest point.

Dressed in his signature pink-feathered coat, he looked down on Zephyr and the recruits below, sneering. "Just as I expected, Zephyr! Letting your emotions guide you is your weakness!"

He raised both hands, connecting to every thread scattered across the deck.

"Off-White Strike!"

Countless threads crisscrossed, slicing toward Zephyr and the Marine recruits he was protecting.

Zephyr could break through this attack, but shielding everyone was a different matter.

Gritting his teeth, Zephyr clenched his right arm, snapping the blood-red thread embedded in his shoulder.

Then—

He raised his pitch-black fist, smashing down hard on the deck below.

The deck shattered instantly.

Ain and the other Marines plummeted downwards in shock.

Without a solid surface, Doflamingo's threads couldn't tighten into a lethal formation.

"No wonder you're an Admiral."

Doflamingo squinted.

With a forceful step, Zephyr rocketed towards him like a cannonball, injured arm clenched into a fist, a swirling gale wrapped around his devastating punch.

"Thread Waves!"

Doflamingo manipulated all the threads on the warship, sending them surging toward Zephyr like white waves, coiling around his fist.

Despite the threads binding him, Zephyr's punch was still fearsome.

He smashed through Doflamingo's Spider's Web defense, his fist penetrating straight through his abdomen.

"Cough!"

Doflamingo spat blood, but his face was still twisted into a crazed grin as he looked at Zephyr.

"Fuffuffuffu… so close!"

Threads from his wound started creeping up Zephyr's arm and torso.

Zephyr was about to shake them off when he felt his right arm go numb.

His strength dissipated.

He frowned.

"Fuffuffu, you finally noticed?" Doflamingo sneered. "Too late."

A sharp line sliced through Zephyr's right arm, where his Haki had already faded.

Blood spurted from the wound instantly!

Gritting his teeth, Zephyr's eyes locked on Doflamingo, his right arm still embedded in the warlord's abdomen.

"Doflamingo… what did you do?!"

"Fuffuffuffuffu!"

Doflamingo's sinister laugh erupted as he reveled in Zephyr's helplessness. "I told you, your attachment to your students is your weakness, Zephyr. That blood-red thread that pierced your shoulder? It was laced with a bit of poison."

Zephyr's eyes widened.

"Fuffuffu, even after being poisoned, you've held out this long. That physique of yours is truly impressive, Black Arm Admiral."

With a twisted smile, Doflamingo pulled Zephyr's arm from his abdomen.

From the gaping wound, countless threads emerged, swiftly mending his internal organs.

Watching this, Zephyr's pupils narrowed. Ignoring the pain from his missing arm, he tightened his left fist, hardened with Armament Haki, and struck Doflamingo again.

"Thread Wave: Reinforced Spider Web!"

Doflamingo strengthened his web, barely blocking Zephyr's punch, but was still sent flying into the air.

Just as Zephyr was about to leap after him for another strike, Doflamingo, mid-air, connected a thread to a cloud above, yanking himself up higher.

"It's been quite an experience witnessing an Admiral's strength—and snagging an Admiral's arm is a decent haul. Let's call it a day; I'll leave the rest of these recruits to you, Zephyr."

Unable to catch up even using Moonwalk, Zephyr roared in fury.

"Doflamingo!"

"Fuffuffuffuffu—"

Doflamingo's deranged laughter echoed among the clouds as his figure disappeared.

...

The warship was silent, broken and battered, debris scattered everywhere.

The deck was strewn with blood and severed limbs.

Of the 60 Marine recruits, 11 had died at Doflamingo's hands, while 17 had been manipulated into killing each other.

"Master Zephyr… your arm…"

Ain and Binz stood among the bodies of their fallen comrades, tear-streaked and sobbing as they gazed at Zephyr, who walked back slowly with one arm missing.

The malice had come too suddenly—those who had been laughing and talking beside them just moments ago had been erased from existence.

Zephyr knelt before the fallen trainees, tears flowing uncontrollably.

In that moment, thunder rumbled across the cloudy sky, and a torrential rain began to pour down.

Ron, gripping his Raikiri sword, stood in a corner, his shoulder-length black hair drenched by the rain, hanging over his face.

Underneath his dark, rain-dampened bangs, his gaze was calm, as still as water.

To him, he could not fully share in the pain that Zephyr and the others were feeling at this moment.

In his mind, he was wondering—

In the original storyline, it was Edward Weevil, who had cut off Zephyr's arm and killed all the Marine recruits except for Ain and Binz. Now, it had been Doflamingo instead.

So, it was his presence that had altered the original plot…
