Raising Legends in Roger’s Shadow Novel

Reincarnated into the One Piece world, Ritter receives the Mist-Mist Fruit and three-color Haki at age three, raised by Pirate King Roger himself. He becomes the ultimate "big brother" of the Grand Line, training future legends like Shanks, Buggy, Ace, and Uta while concealing immense power within his misty abilities. A God Valley Incident veteran and greatsword-wielding swordsman, Ritter balances absurd comedy with genuine guardianship, refusing to blindly idolize even Luffy. As timelines twist and loyalties shift, his hidden identity as the "Mist Emperor" emerges, potentially holding the key to either salvation or destruction for the new pirate age. This One Piece fanfic blends isekai babysitter tropes with dramatic power scaling, featuring a single female lead, comedic moments, and a protagonist whose blood-red mist hints at looming war. Ritter's journey explores what happens when someone rewrites legends from the shadows of history's greatest figures.
