On June 2, 2008, Toei announced on its various official websites that there would be a series of short five-minute internet movies that are spin-offs of Kamen Rider Kiva: King of the Demonic Castle. The featurettes are called Kamen Rider Backwards-Kiva: Queen of the Demonic Castle. In these shorts, Otoya and Yuri are brought into the present by Castle Doran when the mysterious Queen of the Legendorga is about to be revived. The shorts themselves are all zany misadventures of everyone in the Kiva cast.
