In the year 1468 of the Hainan calendar, the sea on Sphinx Island was fishy and salty. Ike, who traveled through eighteen years, struggled to survive on a desert island after his parents died when he was young. He thought he was just an unknown passerby, but unexpectedly found his bloodline with Whitebeard, the leader of the four emperors. He became the strongest cousin from the sky, and from then on he relied on his back to reach the top and roam the sea.
