OVA
Description
Jiro, an android created by Dr. Komyoji to combat the organization DARK, possesses an incomplete "Conscience Circuit" (GEMINI system). This grants him human-like emotions and moral judgment but also leaves him vulnerable to external control, notably Professor Gill's hypnotic flute. Initially activated with a naive, childlike personality and limited understanding, he wanders aimlessly, questioning his identity and purpose.
He forms protective bonds with Dr. Komyoji's children, Mitsuko and Masaru. Mitsuko teaches him to transform into his combat form and explains his GEMINI system. However, their bond fractures when Gill's flute forces him to attack Mitsuko, causing her to distrust him as a "mad machine." This leads Jiro to isolate himself to protect others. Through interactions with humans and battles against DARK's robots, he gradually matures, developing emotions like love for Mitsuko, which she eventually reciprocates.
His conflicts escalate with his robotic "siblings" created by DARK. He reluctantly fights them, showing compassion even towards antagonists like Saburo (Hakaider), who carries Dr. Komyoji's brain and is programmed to kill him. When Saburo threatens to destroy the brain during battle, Jiro pleads for mercy. After witnessing Saburo's apparent death and DARK's base destruction, Jiro strangles Gill but hesitates to kill, revealing his moral conflict. Gill survives by transplanting his brain into a Hakaider body, becoming "Gill-Hakaider."
Later, Jiro encounters siblings Ichiro (Kikaider 01), lacking a conscience circuit and displaying amoral tendencies, and Rei (Kikaider 00), a failed prototype. He allies with them and the female android Bijinder to protect Akira—Gill's son—from SHADOW, DARK's successor. Gill implants submission chips into Jiro and his siblings, corrupting them into violent puppets. Forced to destroy Ichiro, Rei, and Bijinder, Jiro is haunted by guilt. He ultimately kills Gill during the Armageddon Lord crisis, but the submission chip's influence merges with his GEMINI circuit, amplifying his capacity for violence and inner turmoil.
Grappling with this corrupted state and fearing he might harm Mitsuko and Masaru, Jiro remains isolated. A confrontation with the superhero Inazuman helps him break the chip's control. Freed, he acknowledges his actions—including killing his siblings—have irrevocably shaped him. He accepts his dual nature as both machine and human, choosing solitude while retaining hope of reuniting with the Komyoji family someday.
