One Piece 3D2Y: Ace no shi wo Koete! Luffy Nakama Tono Chikai

After suffering great personal loss during the battle of Marineford, Monkey D. Luffy finds himself stranded on Rusukaina, a treacherous island crawling with huge and dangerous creatures. There, he has committed himself to a two-year stretch of training to learn "Haki," the energy that combatants can use to grant themselves a variety of abilities in battle. Luffy is jerked away from his otherwise peaceful training by the abduction of Sandersonia and Marigold, sisters of his friend and ally Boa Hancock. With Boa's aid, Luffy seeks to track down the infamous pirate responsible for the kidnapping, a man whose recent prison break is the result of Luffy's own reckless actions. Luffy must use his developing grasp of Haki to defeat this new foe while coming to terms with his overbearing grief in the process. This new TV special tells the two years of Luffy's training with Silvers Rayleigh in Rusukaina Island after the Battle of Marineford, which has never been told in the manga or TV anime. It also features a new villain named Burndy World who is known as "The Destroyer of the World" and has the power of the MoaMoa Fruit (its ability is still unknown). Luffy has to protect Boa Hancock from the new enemy who escaped from the level 6 of Impel Down. He is newly designed by the original creator of the manga, Eiichiro Oda.
