Years ago, the fearsome Pirate King, Gol D. Roger was executed leaving a huge pile of treasure and the famous "One Piece" behind. Whoever claims the "One Piece" will be named the new King of the Pirates.

Monkey D. Luffy, a boy who consumed a "Devil Fruit," decides to follow in the footsteps of his idol, the pirate Shanks, and find the One Piece. It helps, of course, that his body has the properties of rubber and that he's surrounded by a bevy of skilled fighters and thieves to help him along the way.

Luffy will do anything to get the One Piece and become King of the Pirates!

Nakajima Youko is your average somewhat timid high school student. One day, a strange man named Keiki appears before her, swearing allegiance. Before she could properly register what was happening, demon-like creatures attack Youko and her friends, after which they are pulled into a different world. A world unlike what she has ever known. Separated from Keiki, Youko and her friends must do whatever they can if they wish to survive in this new world.
