Android Kikaider

Deep in the mountains, Dr. Komyoji was about to complete his long time dream in his laboratory when mysterious robot attacks and destroys his lab. Behind the plot is Professor Gil, the evil leader of DARK, an underground organization.

In her search of her father, Mitsuko invites Jiro, the humainoid robot created by Dr. Komyoji, to her but finds out that Jiro has no memory. As she continues her research through data left by her father, she learns that Jiro has a conscience circuit called ""Gemini"" that is equivalent to the soul of a human being.

Jiro stops to look at a puppet clock and hears a boy talk about puppets and remembers Mitsko telling him he's a mad machine. Next, a figure climbs up at a train station and wrecks the train.

Mitsuko has vivid dream of Jiro being killed and realizes she's starting to like him. After searching she finally finds Jiro through the sorrowful sound of his guitar. However, another robot sent by Dr. Gill suddenly appears.

Suspect of destroying the radar tower, Jiro is now on the run from the police. As he wanders around the city, he meets a young woman named Miyuki who tells him that he reminds her of Toru, the man she loves. Meanwhile, Proffesor Gill hires a group of jobless men to blow up the city, one of whom happens to be Toru.

Mitsuko is worried sick about Jiro when Hattori pays a surprise visit to the Komyoji residence. He says he obtained an amazing piece of information concerning Dr. Komyoji. However, suddenly the lights off and Mitsuko is kidnapped in the darkness.
