The one that made it the furthest in the underground, perseverance. Perseverance had beaten almost all of the monsters in the underground from papyrus to sans and undyne but ultimately couldn't finish the task of beating asgore and so his soul was took from him.

*Knowing that Author frequently updates this book...fills you with DETERMINATION.This book is no longer continuing and was closed January 6th, 2017. Are you looking for some fluff? Looking for some Undertale? Maybe for some X Readers? Well, you're in luck. Because this book is full of it! Thank you all for so much support and so many views! I wish I could hug all of you! (Undertale was made by Toby Fox. I do not take credit for any of these characters.)(If you request something while requests are closed OR on the WRONG CHAPTER I will not do it. Thank you.)…

When a situation with a dying human ends up with you absorbing their soul, you panic (like any unprepared monster would). Suddenly Undyne is hunting you down, so you rope the mysterious skeleton next door into helping you. Which he does--in a very Sans way. And who knows? Maybe pretending to be his girl will pay off. | - Classic Sans x Monster Reader - Fake dating turns into real dating - One (1) very mysterious skeleton & one (1) very awkward reader- Papyrus is so sweet and innocent, I love him - Monsters really are in the wrong for killing children tho - I love happy endings and hate tension so expect an easy, relaxing read…
