Ajou is the president of Ajou Heavy Industries and Production Minos. He has a strong fascination (perhaps even a fetish) for mechanical parts and mechanisms, especially the clockwork automatons he collects. Ajou was originally an officer in the Japanese Army during World War II. His fascination with Automatons and his military experience sent him into the weapons business, where he developed the PPOR robot, partially by stealing research notes from Dr. Mima. His goal is to perfect and sell the PPOR as a remote-controlled robot soldier, and for that he needs secrets that only Dr. Mima knows.
