Demogorgon X Reader

Prologue

The Upside Down. One second, the Right Side Up, and now this. Eleven stood up and looked around her. She was still in the classroom- the Upside Down version- in front of the chalkboard. Ashes and black dust littered the floor, which had been dispersed into the air when Eleven disintegrated the demogorgon. Picking herself up, the telekinetic started for the doorway. As she reached for the door, a commotion under the chalkboard stole her attention. The ashes had started spinning again, moving as a roiling grey-brown mass close to the floor. To her surprise, a figure began to appear, faded and hazy at first, but by the time the ashes had faded and disappeared, the demogorgon had reappeared. It lay motionless on the ground, curled into a U-shape. It's back to Eleven, so she couldn't tell if it was dead or alive. But she didn't care. If it had another go at her, she'd just kill it again. 

I'm not scared of you anymore! 

She thought, walking out of the classroom and shutting the door behind her.
