Hunter × Hunter
Before the first anime television series was created, a short film adaptation of "Hunter × Hunter" was shown as part of the 1998 "Jump Super Anime Tour" alongside similar adaptations of "Seikimatsu Leader den Takeshi!" and "One Piece". 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.
Vampire Hunter D (novel)
The novel is adapted into a direct-to-video film of the same name in 1985 and a manga series, "Hideyuki Kikuchi's Vampire Hunter D", in 2007.
