One Piece (Japanese: ワンピース Hepburn: Wan Pīsu) is a Japanese manga series written and illustrated by Eiichiro Oda. It has been serialized in Shueisha’s Weekly Shōnen Jump magazine since July 22, 1997, and has been collected into 94 tankōbon volumes.
The main character of the series, Monkey D. Luffy, is introduced as a child, with his role model, Shanks. After Shanks comes into conflict with a mountain bandit at a bar, it is revealed that Luffy accidentally ate a Devil Fruit, the Gomu Gomu no Mi. Later on, after Luffy provokes Higuma, he is taken hostage. Shanks and his crew show up and defeat Higuma’s bandits, but Higuma escapes, taking Luffy on a boat. After Higuma kicks Luffy into the water, a Sea King appears and eats Higuma, and Shanks arrives just in time to save Luffy’s life. Shanks scares away the Sea King by using Haki, but loses his arm in the process. Because Shanks sacrificed his left arm in order to save him, Luffy becomes even more determined to become a pirate. Before Shanks leaves, he gives Luffy his straw hat. Ten years later, Luffy officially sets sail as a pirate and begins the adventure to fulfill his dream of becoming the Pirate King.
