One Piece fan fiction + native-born protagonist + no System + swordsmanship and Haki + decisive and ruthless + no saintly do-gooder + low-key growth
The Great Pirate Era has begun. Heroes rise on every side, and the seas are rife with bloodshed and ambition.
No foreknowledge from having transmigrated, no System handing out free stat points, and certainly no power from immortal cultivation that overwhelms everything else.
Rayne, a young man from a remote island in the South Blue, steps into these vast and turbulent seas with nothing but an ordinary iron sword and a heart full of passion.
From the most basic sword swings to becoming a great swordsman who can cleave the sky with a single strike;
from desperate, life-or-death battles of flesh and blood to the pinnacle of power, awakening Conqueror's Haki coating.
He navigates the gaps between the Marines and the pirates, crosses swords with Hawkeye and clashes blades with Red-Hair, carving out his own path to survival amid the raging storms of the Paramount War.
“My name is Rayne. I don't eat Devil Fruits, and I have no cheats.”
“All I know is that once Haki and physical combat are trained to their limits, there's nothing in these seas I can't cut through!”
An authentic pirate adventure, with fierce battles where every blow lands hard.
Righting old regrets without changing the main storyline, this time he will reach the summit as an uncrowned king, relying solely on his natural-born body!
I don't know if I can become a pirate later on.
