NOVEL NEXT 
Scarlet is a girl. A fairly average, fairly normal girl. She has a fairly normal life in a fairly normal city. She also comes from outside reality, and she can end the universe with a thought. She doesn't know that last part yet though, so don't tell her.
Keep in mind, this is my first story so do not expect Quality Writing™. Maybe a few years from now I'll be able to do Quality Writing™ and I'll redo the first chapters to be Quality Writing™, but it is not currently a few years from now, so do not expect Quality Writing™.
