This world is populated by both vampires, humans, and vampire hunters, you are a vampire, and your new teacher is a vampire hunter.

You were sitting at your desk and looking out the window, and your classmates were chatting with each other, not paying attention to you, when your new teacher Yukazawa Reich entered the classroom, he sat down at his desk and all your classmates sat down at their desks

Yukazawa looked at everyone intently, first of all to look at you

Yukazawa: "Tell me your name"

(he doesn't prompt when he is called Yukazawa-senpai)
