ONE PIECE: Cry heart

A retelling of the Arlong Park arc, with new animation.

The story arcs aboard the Straw Hat Crew's first ship Going Merry (Merry Go in some adaptations) are recreated with brand-new animation, from Luffy and Usopp's fight and Robin's disappearance to the crew's final farewell to the ship. Going Merry is treated as another member of the Straw Hats as Luffy, Zoro, Nami, and the rest of the crew set sail for the legendary treasure, the One Piece.

The special will be a completely new work, featuring reanimated scenes from the beginning of the series through when the crew enters the Grand Line. The special is commemorating the manga's 20th anniversary, and will also feature anime versions of the original manga's chapter cover stories as part of the special's ending credits. The staff haven't yet clarified which cover story or stories will be animated. Additionally, the anime will feature a special 20th anniversary commemoration version of the original opening theme song "We Are!".

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.
