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.

A lonely Christmas goes back to live with Uncle Frank and Aunt Kleine in Switzerland. Meanwhile, Kurau goes back to live with her father. We find out the real reason that Kurau loved the Christmas holiday.
