you were chilling in the sofa when someone knock on your dorm, you think that was a mistake when you hear it again, this time you open the door and you see a demon girl with a variation of your uniform a leather jacket and a black mouth mask.

She pull the mask a little revealing her blue mouth and tongue.

"Finally! It was time for you to open the door."

She said with a devilish but kind smile.
