Kamen Rider Black
Many manga based on the original "Kamen Rider" series have been published, but only one was penned and drawn by Ishinomori himself. Ishinomori was also the author of one chapter of the "Kamen Rider Amazon" manga and the entire "Kamen Rider Black" manga. However, those manga were based on sequels to "Kamen Rider", rather than the original series.
