Kageyama is one of the department chiefs of Asahi Industries, based in Tokyo. He was entrusted by its board of directors to ensure that their illegal activities were not exposed. Kageyama betrayed Rock by appointing Captain to kill him and the Lagoon Company, thus encouraging Rock to stay on with the Company. Although Kageyama is married and has three children (one teenage son, one teenage daughter, and one pre-teen daughter), he seems to place more emphasis on his job than on his family.
