Ajou serves as president of both Ajou Heavy Industries and Production Minos. He has an intense interest in mechanical components and clockwork automatons, which may be more than just a hobby. During World War II, he was once an officer in the Japanese Army. His fascination with automatons and military experience led him to pursue a career in weapons manufacturing. Ajou's creation is the PPOR robot, which he developed by stealing research notes from Dr. Mima. He aims to refine and market the PPOR as a remote-controlled soldier for commercial purposes. To achieve this goal, he requires information that only Dr. Mima possesses.
