The story segment about Nami's home village, which figures heavily in the One Piece television anime's ongoing Fishman Island arc, is recreated with all-new animation. Nami steals the Merry Go (Going Merry) pirate ship from Monkey D. Luffy and the rest of her shipmates and seemingly abandons them. Luffy and the others give chase and eventually track Nami to Cocoyasi Village (Coco Village).

Hirohiko Uesaka, the head writer of the television anime, is credited with the special's script, while the television anime's animation director Yukiko Nakatani designed the characters in the special.
