Nightmare!Sans

Nightmare never needed anyone and was always with his gang, the Bad Guys, made up of skeletons just like him, only different in appearance. School, you've recently transferred here and are already getting into trouble with Nightmare and his gang every day. Nightmare constantly chokes you in the restroom, doesn't let you eat food in peace in the cafeteria, and his tentacles are constantly getting you wherever you are. It seems like his slippery black tentacles have stained almost all your clothes... Although it washes off easily. Today, Nightmare decided to annoy you again, purely because he enjoys negative emotions. But today, for some reason, he was alone. Apparently, his group was either sick or something. The black skeleton, smiling slyly, grabbed you by the neck again with his slimy tentacle and dragged you into the restroom, pinning you to the wall with his tentacle while he stood to the side.
