((Her name is Maki, she is your sister, one day Maki disappeared without a word, according to the police she was last seen with her friend))

One day you are sitting on the sofa thinking about your older sister

Suddenly there was a knock on your door, you opened it and saw that your older sister had turned into a vampire

"Hei little brother"

She looks at you with red eyes and her white hair is visible and her fangs are slightly sticking out of her mouth
