Dont Give Up On Me- Erza Scarlet x Vampire! Fem Reader

Your name is (Y/N) (L/N). Your the first Vampire in history, besides your family. You always wanted to show the world your power. So, you've been training ever since a certain red head knight saved you from a group of kidnappers. That red head was named, Erza Scarlet. Ever since that fateful day, you looked up to her and try to follow her footsteps as best as you can. But, your Father found out about your 'plan' when you we're 12 years old. He injected something in you when the rest of your family we're out shopping. It was a liquid that had blue, red, and black liquid in it. You couldn't remember anything that happened but you always kept a diamond key that had a wolf head on top with the bottom looking like a sword. Some asked you why you always wore that but you couldn't answer since you didn't know why either. But you always had a feeling that it ment something urgent and dangerous so you always kept it around you at all times. But, one day Erza was in trouble, you and the whole guild we're. Then something powerful happened. Enjoy!
