Produced by Studio Pierrot and directed by Noriyuki Abe, it depicts the early events of the manga up to Gon's ocean voyage from Whale Island.

On March 5, 2018, Yumemakura's agency revealed via Twitter that Mamoru Oshii will adapt the novels for screen. A note by Yumemakura in the 13th volume of the novels confirmed that the adaptation will be an anime film, although Oshii's role in the production was not specified. Comic Natalie later reported that he would serve as director.
