One Piece: I Became Zoro's Big Brother from the Start

After transmigrating to the world of pirates and becoming Zoro's big brother, he knew that if his little brother wanted to become the World's Greatest Swordsman, then he would protect him every step of the way!

Carl obtained a System called the Invincible Sword Domain. No sword technique could harm him. He would gather a crew of sword specialists and, years later, join the Paramount War as Zoro's big brother.

Fujitora: This old man is at your service!

Mihawk: I shouldn't have made that slash in the East Blue!

Shanks: Please, do me this one favor!

Even a random pirate, Luffy, couldn't help but express his envy: "Zoro, I never knew your connections were even scarier than mine!"
