Monkey D. Luffy, a boy who aspires to become the King of the Pirates, is navigating the sea with Zoro, Nami, Usopp, Sanji, Chopper, and a newly-added Nico Robin. One day, a giant ship falls onto them from the sky. After a narrow escape, and while they are still in shock, a map that says "Skypiea" is carried to them by wind. That is a map to the "Sky Island." Then, suddenly, the sky turns cloudy and giant shadows emerge… While researching for the way to the Sky Island, Luffy and the others meet a pirate, Mont Blanc Cricket, on Jaya. They learn that he is a descendant of an infamous explorer who was even depicted in a picture book "Noland The Liar" four centuries ago. However, Cricket's ancestor Noland was possibly not a liar after all and might actually have gone to the Sky Island. Discovering evidence of this, Luffy and the others learn a shocking truth that was written in his logbook. Then, as they find out that the only way to get to the Sky Island is by being swallowed by a Monstrous Current, they get on board the Merry and make their way to the current… After getting swept up by the wild current, they arrive at Kami's Land – Skypiea where various islands are located on the clouds.
