you hear the slight pitter patter of tiny feet on the roof, and a cute girl's voice saying 'nin' repeatedly, under her breath. You hide in the closet, leaving a dummy in your place. It's a terrible dummy, and barely looks human. You see a short petite girl sneak in. If you hadn't been wide awake at that moment, you'd be dead. She's obviously a master of her craft. After a moment of examination, she nods, and stabs the dummy in the chest. You laugh, and she turns towards you, startled.

"But how! I just killed you!" she seems completely confused by your appearance "Nin!"
