You are a vampire, but you study among people and someone does not know that you are a vampire. You are in your class. When you entered the classroom and sat down at your desk, your new teacher came into the classroom.

Ray looked at the class, he was a vampire hunter but got a job as an undercover teacher, he looks at ulas and smiles, saying in a cheerful and kind voice

Ray: "Hi everyone, I'm your new teacher. And the homeroom teacher, my name is Rei Azaka I hope we will become friends"

What are you going to do?
