The vast sea stretched endlessly in all directions.
Waves crashed violently, creating an ever-changing landscape of white foam and shifting tides.
Above the tumultuous waters, a pirate ship cut through the sky, momentarily suspended above the sea before dropping back onto the waves. Its black sails billowed fiercely, displaying a bold pirate flag—a skull with crossed bones, entwined by a majestic blue dragon.
This was Rin's pirate ship.
The flag's design was crafted by Rin himself, inspired by the legends of his previous life. In the mythology of Huaxia, the dragon was the ruler of the seas, an unrivaled overlord. By choosing this emblem, Rin declared his ambition—to become the strongest ruler of the ocean.

Onboard the Ship
Rin sat cross-legged on the wooden deck, holding the Cosmic-Cosmic Fruit in his hands. The moment had come.
Three hours had passed since they departed from the Knight's Kingdom. After securing the ship, he had set sail alongside Artoria and Casa, leaving the kingdom behind. There was no reason to stay—lingering any longer would have been a waste of time.
Shaking his head, Rin exhaled sharply.
With steady hands, he peeled away the thick, rugged skin of the Devil Fruit, revealing the swirling, fleshy interior.
Then, without hesitation—
He took a massive bite.

The Legendary Taste of a Devil Fruit
Rin's eyes bulged as a wave of pure disgust flooded his senses.
"Ugh…!"
A single, overwhelming bitter taste spread across his tongue—a flavor unlike anything he had ever experienced. It was as if he had just chewed on a mix of rotten flesh, burnt charcoal, and seawater-soaked wood.
'Gulp…'
Gritting his teeth, Rin forced himself to swallow.
A shudder ran down his spine as he exhaled sharply. "Damn, that was awful."
Recalling the horrific taste, he knew he never wanted to experience it again.
This was something all Devil Fruit users had in common—no matter how legendary a fruit's ability was, the taste was always utterly revolting.
Shaking his head, Rin hurriedly poured a glass of water, rinsing his mouth to erase the lingering bitterness.
Once he finally calmed down, he tossed the remaining Devil Fruit overboard and returned to his meditative stance on the deck.
Now, it was time to understand his newfound power.

The Awakening of the Cosmic-Cosmic Fruit
Almost instantly, Rin felt something change within him.
A stream of unfamiliar knowledge flowed into his mind, almost as if it had always been a part of him.
It was an intrinsic connection—not forced, but natural, like inherited instinct.
Then, the realization hit him.
"Incarnate the universe."
"Embodied in the cosmos."
Rin sucked in a sharp breath. His heart pounded.
The power of the Cosmic-Cosmic Fruit was beyond anything he had ever imagined.

The True Nature of the Cosmic-Cosmic Fruit
At its most basic level, the Cosmic-Cosmic Fruit allowed the user to create an entire universe inside their own body.
In the beginning, this internal universe was empty—a vast, barren void without form or function.
But then came the true power of the fruit—
Every time Rin defeated and killed a Devil Fruit user, his inner universe would evolve.
Each battle would trigger a transformation.
With every enemy slain, something new would be added—
Meteorites
Comets
Stars
Black holes
At first, this seemed abstract, but as Rin processed the knowledge, he grasped the full implications.
Everything that appeared inside his universe could be manifested in reality.
If a black hole formed inside his universe, Rin could summon it into existence and control it at will.
If a star was born, he could call forth its nuclear energy, wielding the raw power of a sun.
The realization was mind-shattering.
If his universe developed far enough, he could—
Summon meteor showers to annihilate fleets
Create gravitational anomalies capable of warping space
Unleash solar flares strong enough to vaporize enemies
Generate black holes that could consume entire islands
And that wasn't even considering the potential of awakening.
Rin's body trembled.
"This Devil Fruit… is insane."
If the World Government knew about this, they would immediately dispatch all three Admirals to capture him.
It wasn't just strong—it was an existential threat.

Every Power Has Its Price
But Rin knew that no Devil Fruit was without limitations.
Just as Blackbeard's Yami-Yami no Mi (Dark-Dark Fruit) had a crippling weakness, his Cosmic-Cosmic Fruit likely had its own restrictions.
The Dark-Dark Fruit could absorb attacks, but it came with the drawback of negating Logia intangibility, meaning Blackbeard took double the damage from all attacks.
So what were the Cosmic-Cosmic Fruit's limitations?
For now, he didn't know.
His internal universe was still barren—there was nothing inside it yet. That meant, at this moment, he couldn't use any abilities.
To unlock the fruit's true power, he needed to defeat Devil Fruit users and expand his internal universe.
Shaking his head, Rin exhaled slowly.
Regardless of its limitations, the fact remained—
He had obtained one of the most overpowered Devil Fruits in existence.
The rest?
That was up to him to figure out.

A New Beginning
Rin rose to his feet, staring at the endless horizon.
The ship rocked gently beneath him as the wind carried them toward the unknown.
This was only the beginning.
With this power, Rin was no longer just a pirate.
He was a force of nature itself.
