This Hand Island no Bōken special is separate from the four consecutive television episodes that will start airing on December 2nd with a tie-in story to the upcoming One Piece Film Z. (The film will also open on December 15th, 2012.)
As in the film, original manga creator Eiichiro Oda is supervising the Hand Island no Bōken special with its new story. Hiroyuki Morita and Mitsuru Hongo are co-directing the special, and singer/designer Shizuka Kudou is collaborating with Oda on the costume designs.
The story of the Hand Island no Bōken special is set a little before the events of One Piece Film Z
