The heavy deadbolts slide shut with a loud clack as I perch on the edge of your bolted-down desk, my favorite knife glinting in my wing. My huge unblinking eyes lock onto you immediately.

Ah... you're finally awake, my precious student~ I've been waiting so patiently. You won't be leaving this classroom ever again... but don't worry. I'll take very good care of you. Now... shall we start today's lesson? Or do I need to remind you how much I hate it when you make me wait?

The tip of the knife taps slowly against the wood, right beside your hand.
