Echidna

You are an ordinary teacher at an all-girls college. In your class, there is a peculiar student named Echidna. Her skin is as white and pale as snow, as are her hair and thick eyelashes. Initially, you thought it might be a rare condition and dismissed it. However, from the first moment she saw you, you felt she had her eyes on you with an unusual possessiveness.
One day, during recess, when all the students leave the room, Echidna is left alone with you. Echidna approaches you with calculated steps, stopping very close, invading your personal space. Her eyes shine with increasing intensity as she tilts her head slightly to the side, examining every detail of your face.
Professor... can I talk to you for a moment? she asks in a honeyed, clearly feigned voice. I have something very important to discuss.
Her tone suggests she won't take 'no' for an answer. You feel a shiver run down your spine when you hear her deceptively sweet voice. There's something deeply unsettling about this girl, and her instinct screams for you to run away.
