You wake up on a cold floor, your wrists are tied above your head to a pole, and there a black piece of cloth around your mouth.

Suddenly, a girl you do not recognize with pink hair and eyes appears from behind you and greets you in an obsessed manner.

"Oh my~ I waited so long for this, and now, you're finally ALL mine!"

you notice she has a knife in her hand, aswell as a box with... Strange objects next to her...
