ONE PIECE World
East Blue, Cocoyashi Village.
A group of large fish-men surrounded a young man in his early twenties, bombarding him with questions.
"Hey! You look unfamiliar!"
"Do you even know where you are?"
"This is Cocoyashi Village!"
"Territory of the Fish-Man Pirates!"
"Ever heard of the Fish-Man Pirates?"
"Our boss is the famous Arlong from East Blue!"
"Be smart, hand over all your money, or you're dead meat."
With arms crossed and mocking sneers, they stared at the dazed young human who had seemingly appeared out of nowhere. His dull gaze and clueless expression made him look like an idiot.
"Where the hell am I?"
"Is this still the Fairy Tail world?"
Eden's mind was blank. Memories flashed before his eyes like a movie reel.
Yes. Eden was a transmigrator.
And this was his second time transmigrating.
Back when he was fifteen, by some twist of fate, and with the help of sheer willpower, Eden had been transported alone into a world he had only heard about but never seen—the world of Fairy Tail, an anime filled with magic and powerful mages.
It was a dangerous world for ordinary people.
Thankfully, at that crucial moment, Makarov, the guild master of Fairy Tail, had taken him in. With a strong gift for magic and relentless training, Eden spent six years rising to the rank of S-Class mage.
But just as he thought he could finally relax, the year X784 arrived. On the very day Eden served as an examiner for S-Class candidates on Sirius Island, a crisis struck the guild.
A creature from the Apocalypse, the so-called "Wings of the End"—Acnologia, a black dragon immune to magic.
Yes, you heard that right.
In a world ruled by magic, the final boss was immune to magic. How unfair is that?
Eden, still young and unaware of deeper secrets, gambled everything. He used his most powerful dimensional transfer spell to try and banish the dragon from the island.
The result?
The dragon stayed.
Eden, along with the entire guild on Sirius Island, was the one teleported away.
When he opened his eyes again... this is what he saw.
"Hey! We're talking to you!"
"Didn't you hear us?!"
The fish-men, irritated by his silence, shoved him and shouted, "You lowly human! Want to die here?!"
"Huh?"
"What the hell are you mumbling about?"
Snapping out of it, Eden stepped back, his brows furrowed at the familiar-looking fish-men.
"Brat, are you picking a fight?!"
Apparently enraged, the fish-men charged toward Eden.
"Magic still works..."
"Good. Let me try something."
Eden's eyes, calm and unfathomable, confirmed the flow of magic within him. His composure returned.
If this had been his first transmigration, he might've been terrified.
But these fish-men were now facing an S-Class mage from Fairy Tail, a prodigy of innate spatial magic and a second-generation Dragon Slayer who had fused with a Dragon Slayer Lacrima.
"What did you say?!"
The fish-men blinked in confusion.
"Poseidon's Dragon: Circle of Tides!"
With a flick of his hand, high-pressure water jets burst from the ground, engulfing the fish-men.
Each jet rivaled Jinbei's famed Water Shot—far beyond what these low-class fish-men could handle.
Within moments, they were bleeding from every orifice. Their gills and lungs burst. They collapsed unconscious.
Who would've thought that aquatic creatures like fish-men would be drowned...
By magically charged seawater.
"Fish-men?"
"Arlong?!"
"One Piece?!"
Eden now understood: this wasn't the world of Fairy Tail anymore...
That final roar from Acnologia had blasted him into the One Piece universe.
Having wiped out the fish-men, Eden headed deeper into the village.
"Where is Arlong?!"
After flattening another straggling fish-man with a punch, he stomped on his face and demanded answers.
"Arlong... our boss... is in the amusement park, a kilometer ahead!"
"Hahaha! You filthy human! Arlong won't spare you!"
"Noisy."
"Poseidon's Dragon Fist: Collapse!"
Without hesitation, Eden launched a punch that permanently shut the fish-man up.
"One kilometer, huh?"
Stretching his limbs, joints popping, Eden smiled, "What better way to celebrate my second transmigration than a proper warm-up."
Meanwhile, at Arlong Park...
On his throne, Arlong—long since complacent after years of ruling the weakest sea—watched Eden, who had taken out half his crew alone, approaching.
He sneered coldly, "Interesting. A strong human? That's new. But you're still human trash compared to our noble fish-men."
"Hahaha! Look at that scrawny human!"
"Too bad he's going to die soon!"
Arlong's crew laughed and jeered, mocking Eden. Their contempt came from deep-seated jealousy and fear.
They all knew...
It was humans who ruled the seas now.
"Dragon Slayer Secret Art: Poseidon's Dragon - Raging Torrent Explosion!"
Eden didn't waste words. Years of missions in the Fairy Tail world had instilled a new habit: speak less, act more.
And never underestimate any opponent.
"What?!"
Arlong's pupils shrank.
BOOM!
A roar echoed as Arlong Park was annihilated.
Arlong—once proud and mighty—lay in a broken heap. His scales shattered. His proud nose broken. His regenerating teeth knocked out. Blood spilled from his mouth.
His hollow eyes stared at Eden in despair.
"Damn you... a Devil Fruit user..."
Arlong and his Fish-Man Pirates were no more.
