Kamen Rider Black: Hurry to Onigashima

Kamen Rider Black: Hurry to Onigashima ( 仮面ライダーＢＬＡＣＫ　鬼ヶ島へ急行せよ  Kamen Raidā Burakku Onigashima e Kyūkō seyo? ) Released on March 12, 1988 (between ep. 22 and 23) as part of the Toei Manga Matsuri film festival. Originally known simply as Kamen Rider Black during its theatrical release. Children all over Tokyo mysteriously disappear without warning. Kotaro suspects that the Gorgom are behind the abductions and follows a suspicious-looking tour bus with children on it, only to lose its trail off a cliff. With the help of a fisherman (played by Ishinomori himself), Kotaro travels to a remote island and uses his abilities as Kamen Rider Black to save the children and foil Gorgom's latest evil scheme.
