Children all over Tokyo mysteriously disappear without warning. Kohtaro suspects that the Gorgom are behind the abductions and follows a suspicious-looking tour bus with kids on it, only to lose its trail off a cliff.

The city of Yūbari in the Hokkaido prefecture has become a ghost town following the presence of Shadow Moon and his minions of Gorgom. Makino, a scientist working on Gorgom's top-secret robot experiment, escapes from the evil organization and returns to Tokyo, only to find out that his wife and daughter have been abducted. As Kamen Rider Black, Kohtaro travels to Yubari to save Makino's family and liberate the town from Shadow Moon's evil grasp.

A clipshow that's mostly composed of narrated footage of the first eleven Kamen Riders in their series and the then-upcoming premiere of Kamen Rider Black RX.
