The series focuses on Monkey D. Luffy, a young man who, inspired by his childhood idol and powerful pirate "Red Haired" Shanks, sets off on a journey from the East Blue Sea to find the famed treasure One Piece and proclaim himself the King of the Pirates. In an effort to organize his own crew, the Straw Hat Pirates (麦わら海賊団篇, Mugiwara Kaizoku-danhen), Luffy rescues and befriends a swordsman named Roronoa Zoro, and they head off in search of the One Piece. They are joined in their journey by Nami, a navigator and thief; Usopp, a sniper and a liar; and Sanji, a womanizing chef. They acquire a ship named the Going Merry and engage in confrontations with notorious pirates of the East Blue. As Luffy and his crew set out on their adventures, others join the crew later in the series, including Tony Tony Chopper, a doctor and anthropomorphized reindeer; Nico Robin, an archaeologist and former assassin; Franky, a cyborg shipwright; Brook, a skeletal musician and swordsman; and Jinbe, a fishman helmsman; and they also acquire a new ship named the Thousand Sunny.
