Mend Or Succumb.

(Underswap Sans reborn as Underfell Sans)

The last thing Underswap Sans could remember was a human infront him, and yet.. Before he could speak to them, they had walked up with a blade in their hand... And thus ended his life. But as he woke up after the starting pain, he pulled up to feel an immense pain in his head instead... In the moment, Sans took a moment to realize. All that surrounded him was an empty room, nothing but dog toys and a dog bed below him. Where... Where was he??

What if Underswap Sans was reborn as Underfell Sans instead? Perhaps there was some kind of mixup? Or maybe this was on purpose by some god out there... Would Swap somehow be able to fix this universe he woke up in? Or would he succumb to the wrath of every horrible soul in this world, becoming one of them...

(Possibly will make a part two with Fell becoming Swap Sans!! Stay tuned after this book! Art on the cover is by me!)
|TW: Hints of violence, swearing, typical Underfell hell, thanks for understanding!|

Enjoy! ✓
