One Piece (Omnibus Edition), Vol. 17

As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally ate the Gum-Gum Fruit, an enchanted Devil Fruit that gave him the ability to stretch like rubber. Its only drawback? He'll never be able to swim gain-a serious handicap for an aspiring sea dog! Years later, Luffy sets off on his quest to find the 'One Piece," said to be the greatest treasure in the world...
In a desperate battle against time and Gecko Moria, Luffy, Sanji and Zolo must win back their shadows before sunrise or else they will die! When Gecko Moria unleashes his devastating power of a thousand shadows, Luffy counters back with his “Gear” powers. But to save his crew, will Luffy have to make the ultimate sacrifice?
