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.

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.

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.

Mitsuko has vivid dream of Jiro being killed and realizes she's starting to like him.

Suspect of destroying the radar tower, Jiro is now on the run from the police.

Mitsuko is worried sick about Jiro when Hattori pays a surprise visit to the Komyoji residence.

Realizing she's trapped in the same house where she used to live with her mother, Mitsuko's bitter memories suddenly return.

The genius robotics professor Dr. Komyoji has created Kikaider, a humanoid robot gifted with a "conscience circuit" enabling Kikaider to simulate real emotions and distinguish between right and wrong.

After being told her father is still alive, Mitsuko sets out on a journey with Jiro to find her mother, who knows the whereabouts of Professor Gill.

Jiro, Mitsuko and Masaru are still looking for some clue to find Dr. Kimyoji when they accidently run into Chigusa.

With the blue print Conscience Circuit found from Jiro's guitar, Mitsuko learns Gemini has the ability to evolve on its own.

Amazingly, Dr. Kimyoji's brain has been transplanted into Saburo's head while his body is being preserved in the DARK lab.

After taking over Hakaider mind, Dr. Kimyoji helps Jiro infiltrate into the DARK hideout.
