In the world of Undertale, it's supposed to be killed or be killed. This means for many, you have to fight if you're gonna survive. But in a world of fighting on a spiritual plane, how do you fight without a soul? The rumor of red-heads having no soul was nothing but a rumor until the girl was born. Still able to feel the basics of emotion, but without fear or love how will she fair, in the underground? *I have not edited this. I mostly write from 10pm-2am so in unedited parts it may get a bit confusing. Once it's laid out I'll go back and do the editing. Also know that I write approximately 20 pages an update. So if you're not into the longer reader turn back now* *I DON'T OWN ANY OF UNDERTALE!!!! NO CHARACTERS NO NUTTIN! ONLY THE MAIN CHARACTER AND PLOT IS MINE ONLY!!*
