|Japanese name:||東雲 ななみ|
Also known as "Chairman", she was originally a stern, no-nonsense human student who was against the idea of having vampires attend the school, seeing them as making a mockery of all that the school had stood for until then, especially after discovering that the school's chairman and founder was, in fact, a vampire - Mina herself. However, while staying at school late at night, she is attacked by vampires and consequently made into one. Though her original master was defeated, Nanami is soon "overwritten" by another vampire and thus further coerced into serving Mina's enemies. Eventually Nanami is overwritten yet again, this time by Mina, and is able to get some semblance of her life back again, continuing to go to school as Student Council President, but also now serving as a maid for the Ţepeş household.
SpoilerAfter becoming a vampire, Nanami discovers that she harbors deep feelings of lust for her younger next-door neighbor Yuzuru, a boy she had previously considered as a little brother to herself; unprepared for the incredible potency of vampire emotions, Nanami very nearly bites Yuzuru before remembering herself and running off. Overcome with shame and revulsion at what she has become, she even pleads at one time with Mina to kill her, rather than "dirty" Yuzuru with her lust. Eventually however, she comes to realize that Yuzuru, in fact, feels the same way about her, and is allowed to bite him so that they can both be together. Also, because of the age difference between them, Nanami later comes to be labeled a shotacon by Nelly.
