One Piece Film: Strong World

When Monkey D. Luffy and his crew learn that islands in East Blue are being destroyed, they set out to uncover the truth. During their journey, a bizarre pirate ship descends from the sky, captained by the notorious Shiki "the Golden Lion"-a pirate who consumed the Float-Float Fruit and the only man ever to break out of Impel Down. Seeking to overthrow the World Government, Shiki takes Nami hostage to force her into becoming his navigator, stranding the rest of the Straw Hats on his floating islands. Trapped in a world ruled by Shiki, Luffy and his friends must navigate the strange and treacherous landscape to rescue Nami and reunite their crew.
