I drink blood only when neccassary.
Yuuki has the sophistication a pureblood vampire needs. She is calm and graceful and always walks with her back straight, head slightly tilted up and even steps. She was also trained to speak formally but she hates it. Yuuki is always scolded if she makes a mistake at home which leads ti her being very quiet and respectful around adults. Yuuki is sarcastic when irritated. She brings a flute everywhere she goes because she likes it the most.
Yuuki hides a dagger in each of her boots for emergencies.
Yuuki was born a royal pureblood. Her parents are the leaders of the most powerful clan of the Vampire Society. She is supposed to be raised as the heiress of the clan, being her parents' only child, which is why her life growing up miserable. She was not allowed to play with other children her age but instead, had 'Princess' lessons indoors. She learnt how to play the flute and plays it whenever she's sad and it's her favourite instrument. Yuuki goes up to the roof of the mansion to play so her parents can't find her. Yuuki's parents sent her to the academy for a 'Final Test' before she can become the leader of the Valliere clan. Even in school, she is stressed by her parents.
