In the middle of a vast sea, a small boat drifted aimlessly. On it stood a lone young man, staring out at the endless horizon.
His name was Vex… or at least, it used to be.
In his previous life, he had been nothing more than an ordinary office worker. One unlucky day, while walking past an apartment building, a flower pot fell from above and struck him. He was rushed to the hospital—but fate had already decided his end.
He died.
But that wasn't the end.
When he opened his eyes again, he found himself in a completely different world.
The world of One Piece.
He woke up on a small wooden boat, the waves gently rocking beneath him. Memories that weren't his own slowly surfaced in his mind. The original owner of this body had just turned 19 and set out to sea with dreams of becoming a pirate.
Unfortunately for him…
Vex had taken his place.
As Vex sorted through the memories, he realized something shocking—this timeline matched the beginning of Monkey D. Luffy's journey.
"That means… the story is just starting," he muttered.
At first, Vex assumed he had no special advantage—no system, no cheat ability. Just a small boat, limited supplies, and a dangerous ocean.
But that changed.
It happened suddenly.
A strange power surged within him, and before he could fully understand it, his body transformed.
Steel blades erupted from his arms, his body morphing into something no human should be.
He Transformed into something like Katana Devil.
For a brief moment, he had become something straight out of Chainsaw Man.
But just as quickly as it began, the transformation ended.
Five seconds.
That was all he could manage.
Panting heavily, Vex collapsed onto the deck.
"…So it drains stamina like crazy."
After experimenting carefully, he came to a conclusion.
This was a Devil Fruit power—but not one that existed in the original story.
Most likely… a Zoan-type.
And not just any Zoan.
A unique one.
He discovered he had three forms:
Human Form – No changes but has immense strength .
Hybrid Form – Three floating swords hovered behind him, moving at his will.
Full Transformation – The Katana Devil, immensely powerful… but extremely draining.
The floating swords intrigued him the most.
They moved like extensions of his body—fast, precise, deadly.
"…This might actually be broken," he said with a grin.
It was now his second day at sea.
And reality was starting to sink in.
He had:
No navigation skills No map Barely any sailing knowledge Limited food supplies
The original owner had rushed into the sea chasing dreams… without preparation.
"Great," Vex sighed. "I got reincarnated into an idiot."
The boat drifted wherever the currents took it.
No destination.
No plan.
Just survival.
Vex looked out at the endless ocean again, his expression turning serious.
"If this is the world of pirates…"
His hand clenched slightly as one of the floating swords appeared behind him.
"…then I'll have to become strong fast."
Because out here—
Strength wasn't optional.
It was survival.
