Zephyr, now known as Z, rides the seas with only one goal: Destroy all pirates and their dreams at becoming King of Pirates. When Luffy and his crew encounter him at sea, not only are they utterly defeated by the man with an arm made of Seastone, Nami, Robin, and Chopper are turned 10 years younger due to Z's minion Ain. Luffy is so determined to win against him that he does not even notice Z's master plan that could sacrifice thousands of lives.

One day, a giant ship falls onto the Straw Hats from the sky. After a narrow escape, and while they are still in shock, a map to the “Sky Island” is carried to them by the wind. While researching for the way there, they meet another pirate and learn that he is a descendant of an infamous Sky Island explorer who was even depicted in a picture book “Noland The Liar” four centuries ago. However, Noland was possibly not a liar after all and might actually have gone to the Sky Island.
