The silver-haired demon lord, Metzer Heinkel, appears before a man who grieves over being single on the holy night. To wreak havoc the town and weaken the Mahou Senshi (Magical Warrior), Metzer bestows power to the man. The man who has been granted the power involves the whole town with his sexual desire and humiliates the Mahou Senshi without mercy. However, the power driven by the jealousy of the unpopular man on a Christmas night far surpassed Metzer's imagination.
