Kamen Rider Black: Hurry to Demon Island!

Originally released in theaters under the title Kamen Rider Black. Children across Tokyo vanish without warning. Kotaro suspects the Gorgom are behind the abductions and follows a suspicious-looking tour bus carrying children, only to lose its trail off a cliff. With the help of a fisherman, Kotaro journeys to a remote island and, wielding his powers as Kamen Rider Black, saves the children and foils Gorgom's latest evil scheme.
