In the year 1468 of the Sea Circle Calendar, the sea breeze on Sphinx Island carried a salty, fishy tang. Eighteen years after transmigrating, Aike had lost both his parents as a child and struggled to survive on a deserted island. He thought he was just some nameless passerby, until Whitebeard, leader of the Four Emperors, unexpectedly discovered their blood relation. Suddenly, the strongest cousin in the world had appeared, and from then on Aike could roam the seas with a mighty force at his back.
