Years ago, a tragic accident led to Kurau's possession by a Rynax. Now an adult, the Rynax powers she acquired so long ago have made her an unstoppable agent.

Kurau takes on an extremely dangerous assignment, rescuing a space pilot whose spaceship has gone out of control. There are complications, however. Kurau and Christmas are being watched by the GPO, the police department of the future, and a blonde man, who apparently is a private agent.
