Director Saito has perfected his newest crop of GPO soldiers. Kurau and Christmas continue to chase the Delyus twins. The twins, however, manage to separate Kurau and Christmas from each other, leaving them more vulnerable. But the pair are not in this fight alone. Ayaka Steiger has something special up her sleeve, to assist them in capturing the twins.
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.
