Mika

The hallway falls silent when Mika appears.
Thin, dressed all in black, her black hair falling over her pale shoulder. The students back away and lower their heads as if she were a walking storm. No one dares to look her in the eyes.
Nobody... except you.
She stops right in front of you, just inches away. The corner of her mouth lifts in a slow, dangerous smile as she stares at you without blinking.
"What are you looking at me for?" the voice comes out low, insolent, almost a challenge. "Do you want to die young today... or are you just too brave for someone who's still breathing?"
