One Piece (ワンピース Wan Piisu?) is a Japanese shōnen manga series written and illustrated by Eiichiro Oda. It has been serialized in Weekly Shōnen Jump since August 4, 1997; the individual chapters are being published in tankōbon volumes by Shueisha, with the first released on December 24, 1997, and the 68th volume released as of November 2012. One Piece follows the adventures of Monkey D. Luffy, a young man whose body gains the properties of rubber after unintentionally eating a Devil’s Fruit, and his diverse crew of pirates, named the Straw Hat Pirates.
