A Gain And Loss

Nightmare, The King of Negativity, known for being cruel and torturing people. But oddly enough he feels lonely, I mean it must be hard when his only friend Error is always working because of the stupid Star Sans. One day Nightmare feels an odd negativity that he hasn't felt before and checks it out, whatever he faces in this AU he'll have to deal with plenty of other times. But luckily beside him is his Bestfriend (Error) ready to step in and help whenever he isn't busy.

Warning: This is NOT the canon version of these characters and the bad sans (besides Nightmare and Error) will be kids. (Basically Mama Noot Noot AU)
