The little demon

Never in demon history has a demon been to/born on earth, it's the law and even if a demon tried to get to earth they would burn from the sun. The humans and demons made a contract that if a demon somehow managed to get on earth that the demon council can take that demon and do whatever they please but if a human summoned a demon that would be a different story. Though that was 2,000 years ago and most humans think demons are figments of their imaginations. Somehow though a demon was born on earth and that said demon crosses paths with the creepypastas.
