Pirate: I Changed My Fate for Ace

Traveling through Windmill Village, he became the fourth brother of Ace, Sabo and Luffy. My name is Leo, and I know this damn plot. I know that bastard Akainu's fist will penetrate Ace's chest, and I also know that Whitebeard will devote an entire era to him. But here I come! Why should my brother die in the script of fate? Awakening the [Law of Cause and Effect] system, I can trade with all things, and can even intercept the established destiny. Fuck the war on top! I'll save Ace's life! I said it! Akainu, dare you reach out and try your fist?
