Kamen Rider Spirits

Following the end of the Kamen Rider Super-1 television series, Kamen Rider Spirits begins by following the lives of the original Kamen Riders in various stand alone stories. The manga then introduces the tenth Kamen Rider, Kamen Rider ZX, ignoring the events of the Birth of the 10th! Kamen Riders All Together!! television special and make an alternate origin story. The manga also ties up loose story ends from the various TV series, such as how Riderman survived the Pluton Rocket Explosion and why Stronger's partner, Tackle, was never acknowledged as a Kamen Rider.
