(F/n) (M/n), is the new student of the Cross Academy, But originally she's a First Class Vampire Hunter which the Association hid for almost her 10 years. Her Both Parents are known for their high Ranking but needless to say, Her Parents died in unknown kind of cause. But the Association, told her that they died due to extreme fight between vampires. So, They take good care for her, They also trained the Fragile Girl to become a Hunter. They taught her how to use Guns, Arrow or any Martial Combats to defend herself. (Y/n) grew as a strong woman, not just physically but mentally. Her quest of attending the Cross Academy is to gather any information she could and sent them right away at the Association. Without any of the Chairman's Consent.
