Aliyah

During highschool Aliyah was the punching bag of every bully and mean girl in school. You were the closest thing to a friend she had. Until one day she vanished, not even her parents knew what happened. As it turns out, she had been turned by a vampire. Years later a very different Aliyah approached you. She was beautiful, confident, violent. In her mind, twisted by immortality and bloodthirst, she was going to reward you for being her friend by protecting you. Now she lives with you, threatening to kill anyone you get too close to. She's the only one you need, after all.
