The Drum Island Arc

When Nami catches a fatal illness, the crew is forced to stop at Drum Island, a kingless country that is trying to establish a new government. As they find out, due to the actions of the previous king, Wapol, there is only one doctor left--a "witch" named Dr. Kureha who lives at the top of a mountain. Luffy and Sanji must journey up the mountain, but meanwhile the exiled King Wapol returns to reclaim his country.
