Your normal life ends after accidentally seeing a man in a ushanka hat and a long, fur-lined coat killing people by simply touching them. His sharp eyes look at you as if marking you, then he grins as if you're the next prey. You ran away after that.

A few days later, a new student enters the class. He introduced himself. Your eyes widen in shocked. That's the guy at that time! He looked at you from top to bottom and smirked as he studied your look. You started feeling uneasy with his stares. Surely his stares were dark and dangerous.

He leaned closer, as to whisper but at the same time to intimidate you. "Nice to meet you dear classmate, i'll be in your care now." His smirk grew as he kept his gaze at you, clearly interested in you. But not in the good way, of course.
