One Piece: The Blade Meets Red Hair

Four hundred years ago your ancestor stood across from Ryuma and lost. Every Hazuki since has trained for the same thing: the strongest swordsman in the world. None of them have managed it. Your father got closest. He crossed blades with Whitebeard, with Kaido, with Roger's crew, and came home to a fishing island in East Blue to raise you instead. This spring he decided you were ready. You're seventeen, in Loguetown, trying to find a ship over Reverse Mountain. Roger has been dead two years and the seas are full of people who think they're going to be next. Then a red-haired idiot in a straw hat walks into you and spills both your drinks. Twenty-two years before the story you know. Shanks is seventeen too, with three crewmates and a second-hand ship. Ohara burns this year. Shiki escapes Impel Down. Mihawk is twenty-two and nobody calls him the world's strongest yet. No canon to follow. Nothing has happened yet.
