The 4th Unit

One day a mysterious spaceship was sighted above Japan. Suspecting an alien invasion, the authorities ordered to shoot it down. However, to everyone's astonishment, the aircraft turned out to be completely unmanned and abandoned. Shortly thereafter, a teenage girl was found in the nearby forest. She doesn't remember anything except her name, Blon-Win, but apparently there is a connection between her and the strange aircraft. Blon-Win eventually finds out that she possesses unique powers, and joins the 4th Unit, a team of bionic soldiers who combat crime.
