Waking up in Shimotsuki Village at the start, with no system, no cheat.

With no one to rely on, Tia can only apprentice at Isshin Dojo, training desperately, growing stronger little by little.

Swordplay honed to its peak, top-tier martial arts earned through blood and sweat, unparalleled three-color Haki, and Devil Fruit abilities developed beyond imagination.

These allow Tia to gradually reach the world's pinnacle, and slowly, he comes to understand the truth of this world.

This book is a slow burn, with no system or cheat. The protagonist starts somewhat invincible, then becomes even stronger little by little. Readers who are used to fast-paced, invincible system novels might enjoy this system-free change of pace!
