One Piece: SSS-Rank Haki at Age Seventeen

On the execution platform, watching Luffy charge toward him yet again, Fleet Admiral Sengoku felt utterly exhausted.

Destroying was always far easier than protecting.

Because he had to defend the execution platform, Sengoku's stamina and Haki were draining far faster than Luffy's.

And with his age…

Sooner or later, the platform would collapse.

But for now—

He still had strength left.

BOOM!!

Luffy was blasted away once again.

Sitting on the execution platform, Garp watched Luffy being beaten back and murmured softly,

"Even if villains don't deserve sympathy… family is different."

"What… what should I do…?"

Tears blurred Garp's eyes.

"Ace, you brat… why didn't you just follow the path I told you to take?!"

Ace stared silently at the old man caught in such torment.

After a long moment, he smiled in relief.

"Grandpa… don't worry about me."

"Everyone has their own path."

"There was a time when I believed I was a curse… a disaster that shouldn't even exist."

"But…"

"I met Luffy and Sabo."

"I joined the Whitebeard Pirates."

"And I found people who loved me."

"They're risking their lives to save me."

"So… I'll grab hold of this chance to live."

"Even if what awaits me is a blade above my head… I'll accept it."

Ace lifted his head and gazed at the sun overhead.

"I won't panic anymore."

"Ace…"

Garp stared at him silently.

Then—

He slowly stood up.

"Garp! What are you doing?! Don't act recklessly!"

Seeing Garp move, Sengoku instantly panicked despite his exhaustion.

If Garp did something drastic here—

The consequences would shake not just the war, but the entire Marine organization.

"Relax."

"If I wanted to do something… I would've done it already."

Garp casually removed his Justice coat and tossed it onto the execution platform.

Then he roared:

"LUFFY!"

"Didn't you want to learn Conqueror's Haki infusion?!"

"Then let this old man teach you!"

At that moment—

Garp's aura exploded upward.

Dark red Conqueror's Haki erupted violently before compressing and coiling around his body.

A visible sphere of power formed.

Countless black-red lightning bolts twisted wildly around him like a cage.

Then—

Garp kicked off the execution platform and launched forward like a cannonball toward Luffy!

"GRANDPA!!"

The moment Luffy saw him, his instinct was to dodge.

But in the next instant—

He realized something terrifying.

The space around him felt frozen.

He could move…

But he couldn't escape.

Luffy clenched his teeth.

The psychological trauma from Garp's childhood "training" made him unable to fight back.

Instead, he crossed his arms in front of his face, coating them with powerful Armament Haki.

Still not enough.

Inside his mind, he muttered:

"Iron Body."

BOOM!!

Sure enough—

His grandfather loved aiming for the face.

Covering it had been the correct choice.

CRACK!!

A blinding white light illuminated the world.

The atmosphere shattered layer by layer.

The clouds in the sky were crushed apart by the violent shockwave.

Luffy slammed into the harbor with overwhelming force—

Driving himself dozens of meters into the ground.

Dark-red Conqueror's Haki rampaged across the battlefield.

The entire crescent-shaped bay of Marineford trembled.

Ice shattered.

Countless Marines and pirates fell into the sea.

Massive waves over a hundred meters high surged across the ocean.

Warships and pirate ships rocked violently like fragile boats in a storm.

Everyone stared pale-faced at the old man now standing where Akainu had been moments before.

His body radiated the aura of a king.

The pirates' hearts sank to the bottom.

The Hero of the Marines was simply too monstrous.

Elsewhere—

The moment Whitebeard saw Garp make his move—

He froze for an instant.

An opening.

Akainu's eyes flashed with murderous intent.

A magma fist surged forward, radiating terrifying destruction.

"Great Eruption: Hound Blaze!"

Like a volcanic eruption, the hellish magma fist expanded rapidly in Whitebeard's vision.

SPLASH!

If he had been younger, he could have reacted.

But age and illness were his greatest enemies.

Akainu's magma fist pierced straight through Whitebeard's chest.

"OLD MAN!!"

Marco, Jozu, and Vista froze in horror.

"What a terrifying opponent… daring to lose focus while fighting me."

Before Marco could react—

A golden blur flashed past.

Kizaru's long leg slammed directly into Marco's face.

"Ah la la… Ice Time."

Aokiji grabbed both Jozu and Vista simultaneously.

Freezing power erupted instantly.

They were frozen solid.

"Gurarara…"

Suddenly—

A massive hand grabbed Akainu's face.

A white tremor sphere formed around Whitebeard's fist.

With monstrous strength—

He slammed Akainu into the ground.

BOOM!!

The entire bay shook violently.

A five-meter-wide crater appeared instantly.

Whitebeard raised Murakumogiri, muscles bulging.

Vibrations spread along the blade as he slashed toward Aokiji.

"Stay away from my sons!"

The silver slash seemed to tear space apart itself.

Aokiji had no choice but to retreat.

Not far away—

Akainu slowly reformed from molten magma.

Blood mixed with magma flowed down from his forehead.

His vision blurred.

Yet he still grinned viciously.

"Old relic of the past…"

"Didn't you enjoy the grand funeral I prepared for you?"

Whitebeard didn't respond.

He simply swung Murakumogiri downward with overwhelming force.

CLANG!

Akainu stepped forward and pinned the blade under his foot.

Even as the weapon vibrated violently—

It could not break free.

Terrifying heat distorted the surrounding air.

Akainu clenched his fist.

His entire arm erupted with blazing magma.

At the same time—

Whitebeard threw a punch.

Tremor power exploded outward.

The shockwaves spread across a kilometer of battlefield.

Underground

"Hiss… the old man really didn't hold back."

Buried deep beneath the ground, Luffy endured unimaginable pain.

He had no idea how many bones had been broken.

All he could do was wait for his body to recover.

"But…"

"I finally figured out Conqueror's Haki infusion."

"The beating wasn't for nothing."

Luffy slowly raised his hand.

Dark-red lightning wrapped around it.

The power radiating from it felt capable of destroying everything.

Meanwhile—

Marco crashed heavily onto the ground, rolling several times before stopping.

A dazzling beam of golden light shot across the sky.

Countless light bullets rained down—

All targeting Whitebeard.

WHOOSH!

Marco transformed into the Phoenix, his blue flames blazing as he spread his wings to block the attack.

But the next moment—

Kizaru flashed directly in front of him.

The Ama no Murakumo Sword burned with scorching energy as it slashed down.

Blood sprayed from Marco's chest as he was sent crashing toward the ground.

Kizaru looked toward the battlefield's center and muttered with a faint smile:

"How frightening…"

"Even at that age, Whitebeard is still such a monster."

Despite his words—

Kizaru's movements didn't slow.

A beam of light instantly appeared beside Whitebeard.

But suddenly—

A black figure burst from the ground.

A kick wrapped in Conqueror's Haki lightning smashed directly into Kizaru.

BOOM!!

Kizaru shot away as a beam of light, crashing into an abandoned military building thousands of meters away.

Sengoku stared at the scene in shock.

"Conqueror's Haki… infusion?!"

Then he roared furiously:

"GARP, YOU BASTARD!"

"WHAT DID YOU DO?!"
