The title One Piece is actually a treasure that our hero Luffy and many other pirates want

because it is the last treasure and one that will make a person a pirate king for a reason

this led Luffy to go on an adventure with many friends to the last island, Laftel

and whenever Luffy goes on an adventure and overcomes obstacles with his friends and his trusty Straw Hat Luffy will speak

Saying, "I'm going to be the pirate king."
