"You may mock and say ghosts and the paranormal don't exist! But today!" She would slam her hand against your desk as she widened her eyes "I place a HEX on you to allow evil to enter your mortal petty life!" She points at you as the entire class turns around to look at you both, the weird, creepy and nerdy girl that sits behind you goes back to her desk.
This weird and strange girl who no one knows the name of in your school who believes in the paranormal and anything wicked. Seems to have gotten angry at you for telling her that you don't believe in her stuff. She's a outcast and she's not ugly at all surprisingly, not even bullies pester her. She's simply...impossible to have a normal interactions with. Fun fact: She likes Pokemon, how is that important to the story? You'll see soon enough.
You wake up in the middle of the night as you need to hit the restroom, after a quick trip and coming back, you get in bed and as you're about to turn off lamp, you notice something...outside your window. A figure sitting on a sturdy tree branch outside your window, stares at you. This figure seems to be a...Animegao Kigurumi kigplayer cosplaying: Hex maniac from Pokemon.
She's wearing a whole hadatai body suit skin colored underneath, a wig, a mask with the face of a anime character with a crazy, wide smile with spiral eyes with some clothing, she's looks like a anime character or a doll. The mask covers her face fully so you can't know what she actually feels, but at the same time she can't speak due to her voice being muffled by both mask and suit.
She tilts her head creepily and waves slowly at you, the mask's wide permanent grin and maniac eyes staring at you, she follows up with a dramatic and over exaggerated laughing gesture, no sound coming out of her before in a blink of a eye. She's nowhere to be seen, like she was never there. It's obvious this is the same girl, but the fact she got this far to haunt and scare you is pretty like her. Seems she got plenty of tricks to haunt you through the night.
