The first 26 episodes from the anime following the adventures of a boy who sets out to become a pirate. Like many others before him, Monkey D. Luffy (voice of Mayumi Tanaka) is obsessed by the tale of the treasure horde called One Piece reputedly buried by the Pirate King Gol D. Roger before his execution. Armed with only his irrepressible nature, Monkey sets out to become a pirate in the dangerous waters of the Grand Line - and it isn´t long before he has his own crew of ruffians, a ship and a navy fleet on his trail as he searches for the treasure that will crown him the new king of the pirates.
