Wizard Negi Springfield may be a boy, but he has a man-sized job to do! Fresh from the Academy of Magic, Negi continues his training as an instructor at Mahora Academy in Japan. But before he can get his Master’s in magic, the 31 schoolgirls of Class 3-A are gonna keep him up all night cramming for a final exam in will power. Temptation aside, Negi has more on his syllabus than flirting and spells. Darkness is closing in, and Negi is gonna need help from his student bodies to drive the ghouls from their school. These girls want to prove that they’re best in class, and extra credit is available to the cuties that aren’t afraid of after hours phantom fighting – especially if it means more time with their favorite professor.

冷峻英俊的查尔斯·J·克里斯芬多（置鲇龙太郎 配音）是得到梵蒂冈认证的圣职者，同时也是一名拥有强悍战斗力的独立吸血鬼赏金猎人。但他白色身份的另一面，是隐藏着无尽秘密的吸血鬼。他从不吸食献血，是一名虔诚祈祷的圣徒。不过有一个例外，那就是查尔斯的祖先强尼·雷夫罗（藤原启治 配音）。雷夫罗当初利用符咒自行堕落成一名吸血鬼，堪称所有吸血鬼的祖先。他为查尔斯提供源源不断的血液，每当查尔斯前往世界各地执行任务时，雷夫罗便以“食物”的身份随行。这次的任务有些奇怪，修女向查尔斯展示了一名神秘少女，而交换的代价便是查尔斯的主人兼食物——雷夫罗…… 本片根据日本漫画家黑乃奈奈绘的同名原著改编。
