Nanbara

Agent Nanbara was a mysterious man who trailed Keisuke Shimizu and Saeko Kaneshiro from Okinawa to Tokyo, constantly shadowing them as well as alien agent Yanagawa. During Keisuke and Saeko's trip back to Okinawa, Nanbara revealed that he was an Interpol agent when he killed Yanagawa, stopping him from stealing the statue of King Caesar that Keisuke and Saeko had with them. Subsequently, Nanbara helped Keisuke rescue his brother, Professor Miyajima and Miyajima's daughter from the clutches of the aliens.
