The Ultimate Human Robot

Set in the near future, Dr. Nobuhiko Komyoji was the head of the robot engineering project "ARK Project" to use robots peacefully to solve problems beyond human control. Dr. Komyoji however died during an experiment and a year later the project was headed by his rival Kanzaki and the Minister of Defense Tsubakiya who had begun to use the project for their own personal benefits rather than its original objective. To revive the original project, Jiro aka Kikaider, an android with a Conscience Circuit created by Dr. Komyoji has appeared to protect his creator's children Mitsuko and Masaru who have the key to complete the project.
