One piece / Oda, Eiichiro

Having entered the sky island of Skypiea to search for a city of gold, Luffy and crew become caught up in a local fight to eliminate the territory's maniacal leader, Kami Eneru. Luffy and Eneru duke it out in a drawn-out fight, but can even Luffy's rubber limbs and indomitable spirit hold out for long against Kami's arsenal of weapons, including his terrifying and mysterious Golden Bell?.

To reach their next desination, Monkey D. Luffy and his crew on the Merry Go will need to fly to an island in the sky. The characters they meet there are anything but heavenly, however, and Luffy and the Straw Hats are soon on the run--toward a city of gold!.

The Straw Hats, separated from each other and awaiting the ominious foretelling by Kami Eneru that only five of them would be left after three hours, eventually meet on the battlefield where the war for Skypiea is being fought.
