[Naval Forces] [Hard Work Makes You Stronger] [Rust-Rust Fruit] [Vice Admiral-Level Strength from the Start] [No System]
Reborn in the world of One Piece, he grows up in the Navy, studies under Zephyr, and becomes Shuen, the man of rust who ate the Rust-Rust Fruit.
He has an inherent, hidden golden finger: he can break through the limits of his talent, and hard work always brings a reward.
A monstrous physique, earth-shaking Haki, strange and versatile Devil Fruit powers, extraordinary knowledge and skills...
Whatever he wasn't born with, he can gain through hard training!
This sea has been rusting for far too long. I'll make up for the regrets of justice!
Watch Shuen develop patiently and build up his ultimate strength, then strip the rust from justice and forge new steel in the name of a new kind of Navy!
