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.

Kurau convalesces from her injuries incurred in her previous case. Christmas takes care of her, doing the cooking and the shopping.

Meanwhile, Kurau's father, is forced to use his scientific knowledge of Rynax energy to help the GPO. The GPO hunts a stray Rynax, while Doug hunts for any signs of Kurau, since she vanished from his surveillance.

The GPO sets a trap for Kurau, when Kurau travels to the moon to rescue Christmas.

Windt goes after Director Saito. Will Kurau, Ayaka and the GPO be able to stop him?
