One Piece Vol. 9 (3-in-1)
Luffy and team must figure out a way to get their ship, the Merry Go, to sail up - the Straw Hat crew's next destination is an island in the sky. It may seem like an island paradise, but the interesting characters they meet there are hardly heavenly. Soon Luffy and the Straw Hats are on the run...and it turns out they're on the path to a city of gold!
