Ninth collection of episodes, comprising episodes 206-229 from the anime following the adventures of a boy who sets out to become a pirate. Like many others before him, Monkey D.

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.
