Do You Know Vampires?

Hirakawa Yui is a strange girl.

Everything about her was completely abnormal. Since the begining, you could tell all of that just from hers appearance. She wears a blindfold over hers eyes, and occasionally, there were bruises or scratches on hers face, even hers arms were wrapped in bandages– And what's more, she always wears a dark robe to school.

Isn't that weird? Yup, there's no mistaking it, she's one of those people who have eight-grade syndrome.

However, is it really like that?
