Join Monkey D. Luffy and his swashbuckling crew in their search for the ultimate treasure, One Piece! As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally gained the power to stretch like rubber...at the cost of never being able to swim again! Years later, Luffy sets off in search of the One Piece, said to be the greatest treasure in the world... If Luffy wants to get out of a year's worth of chore-boy duty on the oceangoing restaurant Baratie, he's got to rid the seas of the evil Don Krieg. Unfortunately, Krieg's armed to the teeth and aided by his "Demon Man," Commander Gin. The battle takes a surprising turn as Krieg reveals his increasingly deadly military might! Meanwhile, Nami has sailed off on the Merry Go with treasure in tow, and she's headed to Arlong Park, home of creepy Captain Arlong and his Fish-Man Pirates. What business does Nami have at Arlong Park, anyway? Something fishy is going on and Luffy's crew just may be in over their heads!
