A.i.r.

The Quasar Empire needed to expand in order to provide enough living space for its inhabitants. They sent a scout to the neighboring Beta Galaxy, with whom they had signed a peace treaty before. However, Beta authorities treated the scout with suspicion, fearing that Quasar Empire would break the treaty and assault them to further their goals. On the way back the scout was killed. A member of a special team known as the Anti-Intruder Rangers is sent to space with a clear objective: find the scout's remains and retrieve the vital information he carried.
