One Piece: sign-in to Ryujin Jakka

Boom—

The sky turned crimson.

Roman raised Ryujin Jakka high above his head. The aura of a peak-level Swordsman surged like a tidal wave.

No unnecessary flourish. No extra motion.

Just a simple, downward slash.

The Zanpakutō fell.

Swoooosh!!

A howling gale exploded outward.

The blade ripped through the atmosphere. The air screamed as it was torn apart. Illusory flames surged, consuming all the heat around.

And then—

Heaven and Earth changed color!

The blazing sky was instantly swallowed by this world-shaking strike.

The massive magma fist launched by Akainu?

Disintegrated.

It became nothing but fuel for the fiery arc roaring toward the horizon.

HSSSSHHH!!

The slash skimmed across the ocean, boiling the sea with its heat, vaporizing waves in an instant.

Like a crescent moon, it blazed forward, charging directly at Akainu!

The slash radiated brilliance and overwhelming power.

Even the most seasoned soldiers turned pale!

The Marines on the sea stood frozen, staring at that flaming arc like deer before a train.

Only now did they truly feel it—

That suffocating, bone-crushing pressure.

Their bodies locked up in pure instinctive fear.

And that was just the aftershock.

The one who felt it the most—

Was Akainu.

Every cell in his body screamed under the weight of the pressure.

He watched in horror as his own magma techniques were devoured like leaves in a furnace.

His heart... plummeted into an abyss.

'I can't win... I'm no match for him...All I can do is... wait for death!'

Akainu clenched his fists tightly.

If he could go back in time, he'd train harder. He'd push himself even more ruthlessly.

But it was too late. There was no next time.

BOOOOOOM!!!

The slash landed.

It cleaved down with unstoppable force, striking Akainu directly!

Even with the Magma-Magma Fruit, he couldn't withstand the temperature.

He could feel it—

His powers were being suppressed,

Overridden,

Like he'd run into a superior fruit.

WHOOOOOOSH—

The shockwave erupted, stirring up the ocean into a monstrous frenzy.

A tsunami rose.

"Quick! Helm hard to port! Full speed ahead—don't get caught in it!!"

"What about Vice Admiral Akainu?!"

"Forget him! He disobeyed orders and charged in on his own! This is on him!"

"Save yourselves first!"

Above Ohara.

The winds howled. Roman's cloak fluttered wildly.

He calmly sheathed Ryujin Jakka.

Then, his voice carried over the inferno:

"Reduce All Creation to Ash…"

The slash in the sky transformed.

A massive fireball appeared, glowing with terrifying might.

It descended, pressing down on the tsunami and the warships fleeing for their lives.

Tens of thousands of tons of seawater... evaporated in an instant.

In the end, the only ones left unharmed—

Were the people of Ohara.

Robin and Olvia stared at the blazing ocean.

Shocked.

Speechless.

No one knew how long had passed...

The flames gradually dissipated.

And on the sea—nothing remained.

Robin's eyes sparkled with starlight.

She turned toward Roman, eyes full of awe.

"Big Brother Roman... you're so strong! I want to be just like you when I grow up!"

Roman chuckled.

She had already made him her life's goal.

In every possible way.

He looked at her and thought:

'She's growing fast. Just a few days, and she already shows signs of her future self.'

"Robin, work hard. Did you see those clouds of fire? That's what Devil Fruit awakening looks like. If you can reach that level, you'll be a force to be reckoned with—whether it's in the Four Seas, the Grand Line, or even... the New World."

Robin nodded earnestly. "I'll train harder! I want to awaken my fruit powers as soon as possible!"

Roman gave an approving nod and turned to Olvia.

"I'll leave Weevil with you. If anything happens, let him handle it. Just make sure he has a cloak to wear."

"I understand. Roman, are you leaving already?"

"Yeah. Time's tight. I'll come back when I can—or you can come find me out at sea."

Robin clenched her fists. "I'll awaken soon, and I'll come find you!"

After saying their goodbyes, Roman activated his Rooster Talisman and soared off toward Marineford.

But of course, he couldn't just fly all the way back.

A day passed.

Roman found a small island and bought a ship to continue his voyage.

Yet, just as he reached the beach...

He blinked.

There, lying face-down in the sand—

Akainu.

His body was covered in burns. His skin was rotting and pale.

Blood seeped from his wounds, but—

He was still alive.

Roman walked over, crouched beside him, and began examining the injuries with his peak medical skills.

"Akainu, oh Akainu... should I save you? Or just leave you here?"

A real dilemma.

He sat cross-legged in the sand, arms folded.

He had time. Akainu wouldn't die just yet.

Half an hour passed—

And Roman had fallen asleep.

He yawned, stretched lazily, stood up, and dusted off his pants.

A sly grin crept onto his lips.

"Akainu... try not to die just from being played with by me in the future."

He hoisted Akainu up and dragged him onto his newly bought ship.

Then, Roman got to work.

Top-tier medical arts.

Except—this time?

No mercy.

He struck and kicked Akainu's pressure points mercilessly.

Agonizing pain surged through Akainu's nerves.

He coughed up a large mouthful of thick, black blood.

It was old, clotted blood that had built up in his body.

After vomiting it all out, Akainu's eyes slowly opened.

He looked up, weak and pale, and saw Roman.

A hint of relief flickered in his eyes.

"Roman... you're alive... was it you who saved me?"

Roman smirked.

"Who else could it be? But damn, for someone this wrecked, you sure managed to hang on. That's pretty impressive."

He gave Akainu a thumbs-up.

Akainu's eyes shimmered with faint gratitude.

"…Th-Thank you…"

It was awkward. Forced. Like he'd never said those words before.

If only he knew—

It was Roman who put him in this condition.

Might've died on the spot from sheer rage.

Roman's eyes twinkled with mischief.

"Rest up. We're heading back to Marineford. If I don't show up soon, they might really think I'm dead…"
