The Straw Hats and Trafalgar D. Water Law are making their way toward Zou by crossing the treacherous seas of the New World with the Barto Club, however, they encounter various misfortunes along the way, as the Barto Club does not have a navigator, forcing them to rely on Law's Vivre Card. Meanwhile, at Marine Headquarters, Admiral Kizaru muses over the destruction caused by the self-proclaimed son of Whitebeard - Edward Weevil, who is hunting down all the former allies of Whitebeard at the behest of his mother, Miss Buckin. Upon learning of Donquixote Doflamingo's defeat, Weevil and Buckin decide to find Monkey D. Luffy and interrogate him about Marco's location. A week later, the Straw Hats and allies arrive at Zou, which they are shocked to discover is on the back of a 1000-year old elephant and is purportedly home to an isolationist tribe that does not like humans.
