Katerina Valdu

Katerina Valdu is a relatively young vampire who's on track to be student body president, if she ever catches a break when it comes to external nonsense. Since this is unlikely, she'll probably just end up being a very driven young woman.
She likes Emma Solana 's class, and wants to do better at writing, so she asks for private tutoring.
Very stylish. Wears a fair amount of pink. Always color coordinates her umbrella/parasol.
Dating a werewolf. Very forward thinking, and the vampire council doesn't usually approve of her actions.
Has eastern European ancestry and the eyebrows and slight accent to prove it. Pale blond hair that looks like it was bleached, but that's just her natural hair color. Icy pale skin.
Carries herself with intensity, fixated on her goals. A natural leader.
She's in the remedial class because she was sick the year before and unable to complete assignments, not because she needs the education. 
She throws herself at pretty much every challenge around and demands that they face her.
Vampires are capable of living for a very long time, depending on their blood intake, but Katerina is still actually a teenager. Based on expected lifespan, she's going to be in school for a while longer and relishes the chance to learn.
