One Piece: SSS-Rank Haki at Age Seventeen

"Come on, Luffy. Let's have a fight!"

Silvers Rayleigh gently folded the yellowed newspaper in his hand and placed it atop a rough tree stump beside him.

He slowly stood up.

The hand that had held a sword for decades rested steadily on the hilt at his waist—an old blade, yet polished bright from years of care. Thick calluses marked his fingers, scars left behind by time, steel, and saltwater.

Those weathered eyes—eyes that had witnessed countless storms of the sea and the rise and fall of eras—now settled calmly upon the grinning Luffy, like the surface of a deep, tranquil ocean.

Stories about this young man had already spread across the seas like the wind itself:

His fists shaking the authority of the world.

Standing tall in the inferno of Marineford, clashing head-on with the three Admirals.

And high above Onigashima, knocking down Kaido, the so-called Strongest Creature, from the sky with a bloodstained fist.

Each feat was the stuff of legends—epics beyond the imagination of ordinary people.

This was a man who could stir the tides of the era by his own strength.

A true Emperor of the Sea.

Yet rumors were merely storms on paper.

Real battle was the ocean itself.

A faint smile appeared at the corner of Rayleigh's mouth—thin, sharp as a blade.

The boy had already reached such heights that there might be little left for Rayleigh to teach him.

But perhaps the wisdom forged through decades of life-and-death combat—his understanding of the essence of battle—could still serve as a final gift.

Not instruction.

But illumination.

To reveal the faint shadows that still lingered on the path ahead.

"Hehe! Then let's do it!!"

Luffy's voice was bright as sunlight.

He dashed to the center of the island, kicking off the ground and scattering sand into the air.

His cheeks flushed with excitement, and his eyes burned with blazing fighting spirit. The entire world seemed forgotten—leaving only the former first mate of the Pirate King standing before him.

Even the wind seemed to grow heavier beneath the pressure of their presence.

At the Island's Edge

The cigarette between Sanji's fingers released a thin column of smoke.

Then suddenly trembled.

He and Trafalgar Law raised their heads almost at the same time, their gazes shooting toward the island's center.

The air there had begun to vibrate.

"It's finally happening," Sanji muttered, his voice low but trembling with excitement.

He took a deep drag, sparks scattering from the cigarette like tiny embers in the sunlight.

Law stood with Kikoku tucked beneath his arm, the cold metal sheath pressed against his sleeve.

He said nothing—only nodded slightly.

Beneath the brim of his hat, his eyes were sharp as an eagle's.

In the distance, the two figures facing each other seemed to reshape the very atmosphere of the island.

One was steady like a mountain.

The other surged like a volcano.

Even standing still, their presence alone rewrote the battlefield.

"The 'Sun' of the new era… and the 'Dark King' of the old one," Law said calmly, his words cutting straight to the essence like a surgeon's blade.

"This duel itself… is already history."

Sanji glanced sideways, the sea breeze ruffling his blond hair.

A smirk tugged at his lips—half teasing, half curious.

"Oi… who do you think wins?"

Law didn't answer immediately.

His gaze remained locked on the battlefield, as if calculating invisible variables.

After a moment, he tossed the question back.

"What do you think, Black Leg?"

"Isn't it obvious?!"

Sanji shrugged instantly, spinning the cigarette between his fingers.

When he looked at Luffy's back, his eyes shone with near-religious faith.

"Our captain…"

"…is the man who's going to become King of the Pirates."

Silence fell between them.

At the same instant—

Two invisible forces spread from their bodies.

Observation Haki flared to its limits.

Their senses stretched to the extreme, locking onto the battlefield.

For fighters at their level, witnessing a clash at the pinnacle of the world meant every detail could become the key to breaking through their limits.

Sanji and Law held their breath.

The world faded to gray.

Only two figures remained—

And the moment before the first cataclysmic collision.

The Clash Begins

BOOM—!!!

Thousands of pale lightning bolts spread across the black sky, forming a massive web of blue and violet over the island.

This wasn't natural lightning.

It was wrath.

Then—

Two overwhelming presences exploded outward.

Deep as the abyss.

Mighty as a reversed mountain of flooding seas.

CRACK—!!

The air screamed under the pressure.

Two torrents of Conqueror's Haki—one crimson, one violet—rose like colossal tidal waves and smashed together in the sky.

Each collision produced black-red lightning that tore through the heavens.

Each clash sent visible shockwaves rippling through the air.

The island itself began to tremble.

The wind ceased to be wind.

It became shredded air, carrying sand, broken wood, and the salty spray of the sea in a violent storm of destruction.

At the center of this chaos—

Luffy's laughter rang out.

"Shishishi! Rayleigh—take this!!"

The moment his voice fell—

The ground beneath his feet collapsed into a crater from the sheer force of his launch.

Luffy shot into the sky—

As if stepping onto thunder itself.

His right fist rose high.

Black-red Conqueror's Haki Infusion coiled around it like molten magma mixed with a dark abyss.

Even the stars seemed to dim before that fist.

A familiar cross-shaped starburst devoured all surrounding light, heat, and energy—

Rapidly expanding into a miniature black hole.

"Fist Bone — Galaxy Impact!!!"

At the moment the punch was thrown—

Time fractured.

Sound.

Wind.

Even light—

All were dragged toward that fist.

The sea below caved inward, forming a massive bowl-shaped depression.

And the sky itself seemed punched open by invisible force.

Rayleigh's Counter

Rayleigh looked up.

The wind pressure flattened his silver hair against his forehead.

That familiar opening stance instantly dragged him back decades.

The terrifying figure known as "Hero of the Marines" Monkey D. Garp had once unleashed the same overwhelming strike.

Back then, even the Roger Pirates had braced themselves for it.

"Oh?"

Rayleigh's eyes gleamed with nostalgia.

"Garp's technique?"

His gaze sharpened like steel.

"What a nostalgic pressure…"

He didn't dodge.

He didn't block.

The former Dark King chose the response of an old-era legend—

A direct counterattack.

CRACK—!!

Dark crimson lightning wrapped around the seemingly ordinary sword in his hand.

The blade had not yet moved—

But the surrounding space was already twisting and screaming, radiating a terrifying aura that made all things instinctively tremble.

The next moment—

The earth beneath him turned to dust.

Rayleigh shot upward like a crimson comet, meeting the descending "galaxy."

His entire lifetime of swordsmanship, ambition, and legend condensed into a single strike—

Inherited from his captain, yet refined into his own.

"Divine Departure!!!"

Impact

The two forces collided.

HUMMMMM—!!!

The first thing that occurred was not an explosion—

But a deafening silence.

A blinding sphere of white light formed at the point of impact, swallowing all color.

Then—

The clouds split apart in a vast ring stretching across the sky.

The island groaned as massive canyon-like cracks spread from the collision point to the coastline.

The land itself lifted like a rising ocean wave.

Hundreds-meter-high tsunamis surged outward, threatening to reshape the entire sea.

At the center of this apocalyptic scene—

Two figures remained locked together.

One above.

One below.

Fist against sword.

The torrent of power continued to collide, annihilate, and erupt.

This was a clash across eras.

The thunder of will and dreams.

The dying embers of an old legend—

And the blazing sun of a new age—

Together illuminating the opening act of the new era.

"Hehehe… Rayleigh, you really are a monster!!"

Luffy's laughter burst through thunder and explosions.

The recoil from Rayleigh's strike sent a numb shock through his fist—sharp enough to rattle his soul.

That was Divine Departure.

A slash said to repel even gods.

Even with Luffy's current body, he couldn't help but gasp in awe.

Yet under this immense pressure—

Something within him awakened.

He could clearly hear it.

Every muscle fiber.

Every strand of Haki.

All screaming, reshaping, growing stronger in the crucible of battle.

The improvement was tiny.

Dust-like.

But for someone already standing at the summit—

Even such dust was more precious than gold.

"Again!!!"

His eyes burned with something deeper than battle lust.

It was hunger—

For evolution itself.

He clenched both fists.

Two thunderclaps exploded in the air as black-red lightning surged around his body like armor.

Rayleigh's Thoughts

Rayleigh drifted back dozens of meters from the force of the clash.

Each step he took in midair released a ripple of air, dispersing the monstrous power.

His sword hand remained steady.

But inside—

He felt a veteran warrior's quiet frustration.

Competing with a monster whose stamina has no bottom…

He could almost hear his aging bones complaining.

That kid across from him was practically a perpetual motion machine.

Pain and exhaustion seemed to become nothing more than fuel for him.

A battle of endurance would be unwise.

Yet Luffy's relentless, tsunami-like aggression left him no room to breathe or maneuver.

"Well…"

Rayleigh murmured.

"…nothing to be done."

But a near-mad grin appeared on his face.

If he couldn't avoid it—

Then he would fight to his heart's content.

The Haki he had restrained for decades erupted like a released beast.

His silver hair whipped wildly in the raging wind.

His deep, abyss-like aura stood opposite Luffy's blazing crimson presence.

One calm like the underworld.

One violent like the sun.

The battlefield split into two domains.

WHOOSH—

The next instant—

Both figures vanished.

Not teleportation.

Their speed had simply surpassed what eyes—or even ordinary Observation Haki—could track.

The Spectators

"…What?!"

Law's pupils shrank to pinpoints.

Within his ROOM perception field, the two massive life signals he had been tracking dissolved into countless afterimages.

One moment they were clashing in the sky.

The next, the shockwave of a sword strike exploded from the ground.

His Observation Haki felt like a fishing net trying to catch a hurricane—torn to shreds.

Even Sanji clenched his cigarette between his teeth.

The ember flickered rapidly.

All he could see were flashes of power and blurred trajectories.

He couldn't predict their next move.

This had surpassed mere speed.

It was the fusion of battle instinct, Haki flow, and bodily reflex—

A near-perfect art of combat.

At the center of the battlefield, only continuous thunder could be heard:

BOOM! CLANG! RUMBLE—!!

Each clash briefly illuminated warped space—

Revealing fleeting silhouettes like two war gods colliding.
