Miya Uemura was kidnapped by Neo-Shocker while visiting Mt. Daiba. They proceeded to perform the cyborg modification operation on her, transforming her into Sasoranjin. Placed under General Monster's command via remote control, Miya is used as an assassin to murder any scientist who refuses to join Neo-Shocker and take their research. Realizing the attack pattern, Tsukuba and Shido lay a trap for Sasoranjin that results with the necklace, the receiver of General Monster's mind control, destroyed. Though Miya regains her memories, briefly reunited with her younger sister, a planned flaw in her system causes Miya to revert to her cyborg form. However, Sasoranjin retains her free will as she is mortally wounded by arrows from Ari Commandos in her attempt to kill General Monster. By the time Skyrider arrived, Sasoranjin reverts to her human form and dies while asking the Kamen Rider to look after her sister.
