ONE PIECE: NENRYOKU NENRYOKU NO MI(NEN-NEN FRUIT)
[Pirate Faction] [Slow Burn] [Gradual Growth] [Nen-Nen Fruit User] [Great Swordsman] [Master of All Three Haki] [Float-Float Fruit is Fake] [No Female Lead]
“Hey, hey, hey~~”
Shiki, the Golden Lion, scowled as his massive ship drifted unnaturally in midair.
“Roy… why is your Nen-Nen Fruit stronger than my Float-Float Fruit?”
Roy leaned lazily against the mast, a sword resting on his shoulder.
“How would I know? Maybe because mine isn’t outdated.”
Around them stood figures who, in another timeline, would become legends:
Douglas Bullet, still a battle-hungry rookie monster.
Dracule Mihawk, sharpening his blade before he became the world’s greatest.
Gild Tesoro, not yet the king of gold.
Crocodile, still learning how far ambition could carry him.
They all boarded Roy’s ship—drawn not by loyalty, but by the undeniable pressure of his will.
Roy had arrived in this world by accident, awakening the mysterious Nen-Nen Fruit, a power that allowed him to refine aura, intent, and willpower into tangible force. Not a Logia. Not a Paramecia. Something stranger. Something that resonated unnaturally well with Haki.
He trained. He fought. He sharpened his sword until even Mihawk acknowledged his edge.
He awakened Armament hard enough to crack steel, Observation keen enough to read killing intent, and Conqueror’s Haki that bent weaker wills to silence.
Yet Roy did not rush.
This era was still young.
So were the monsters of the future.
Years passed.
Then one day—
A boy in a straw hat set sail from the East Blue.
Roy stood at the prow of his ship, watching the horizon.
“…Ah,” he muttered. “So it’s finally starting.”
By the time Luffy entered the Grand Line, Roy’s name had already become a whispered terror among pirates and Marines alike.
Not a Yonko. Not a Warlord.
Something outside the system entirely.
When Luffy finally stepped into the New World, Roy turned to his gathered crew—men who would one day shake the seas.
“Brothers,” Roy said calmly, resting his hand on his sword.
“You go on ahead. I’ll see for myself what kind of man this Straw Hat really is.”
And thus, the era quietly shifted.
Not because Roy conquered the world.
But because he stood in its path, waiting.
