Characters » Alucard Maria
Birth date: February 9
Maria Alucard is Magami Academy's 3-C Homeroom teacher, the class of Tatsuma, Kyouichi and Aoi. She can be somewhat childish as a teacher, often losing her temper enough to scream and throw things at students who get out of hand. She is rather annoyed by Kyouichi, who calls her "Maria-chan" and always comes up with excuses to skip class; she's also not fond of Tatsuma's habit of sleeping through her class.
The voluptuous, beautiful teacher is popular amongst the kids, undoubtly because she can behave like a kid herself. She rides a motorcycle to work everyday, and because she is the English language teacher, she often speaks in English outside of class. Although she is hard-pressed to admit it, she is very protective of her students, and often pries Morihito Inugami for information regarding the whereabouts of the mysterious Magami Five. Like Inugami, Maria seems to understand about the supernatural powers that be more than a regular human should...
SpoilerShe is, in reality, a vampire-like oni (demon). Maria Alucard gets some focus in a brief arc in season two, where a short flashback shows her as an aristocrat in an early-century France, watching her family burn at the stake. She seems to be living her life in secrecy; not hunting, but being hunted.
Maria reveals towards the end of the anime that she had hated humans, and wanted to do them harm. But the conflict seemed to have caused a change of heart, and she now professes to Inugami that she wants to protect her students, having come to accept their affection.
