Princess Anserine of Vespentia faces a brutal fate: forced to wed the sadistic Prince Mortis to save her besieged kingdom. Trapped in a lonely tower and abandoned by her cowardly father and ungrateful subjects, she cries out for any force to end her despair. The ancient vampire lady Sevillina answers her plea, sweeping Anserine away to her shadowy gothic castle and claiming her as a prized pet canary.
