Many of you have heard of The Royal Judge, Sans. But, have you heard of The Royal Executioner? His name is Y/N, and he is The Royal Executioner of The Underground. He thought his job was pretty boring since nobody ever fell into The Underground anymore. However, little did he know that his life would change forever when someone with the soul of Determination came into The Underground & started slaughtering everyone. Even Sans fell to their hands. Now, all that's left between them & the total destruction of monster-kind, is The Royal Executioner, Y/N. Can Y/N stand against someone who can't even stay dead? Can he save all of monster-kind from this Genocidal path? If there's one thing that he knows better than anyone else, even Sans, it's that Determination is deadliest Soul known to exist. He has sworn to fight, To His Final Breath, no matter what would befall him. Little did he know though, Chara was still watching over him. . . Now, a question he must ask himself; How long will he have to wait for a pacifist route, or will it come sooner than he thinks? And what will it cost for the freedom of all monsters, to destroy The Barrier once and for all?

My Fault - Underfell Fanfiction (Sequel to Your Fault) by DragonzRawesomE
20 parts Complete Mature
{COMPLETED} It has been just two weeks since the event that changed Papyrus' life forever. Too late, it seems, he realized what he had. And now that it is gone, he has fallen to pieces. How, or if, he will be able to cope, he truly does not know. And as if that wasn't enough, there are countless mysteries in store for this burdened skeleton-- coming from people he thought he could trust, and in places he thought that he knew. Will Papyrus ever be able to solve the mystery behind this devastating chain of events? Or will he, too, fall prey to the ever-expanding void that is engulfing the souls of himself and everyone around him? PLEASE NOTE: This book is the second in its series. It contains major spoilers to the first book, as well as this book may not make much sense without having read it first. So, if you want to keep the excitement of the first book without any major spoilers, I HIGHLY suggest going and reading that first. It is titled Your Fault.

It's only been a few years since monsters have been released from their underground prison. In some towns, monsters are welcomed with open arms. Others? Not so much. Y/N is a 22 year old girl that lives a pretty simple life. Sleep, eat, work, relax at her daily cafe, go home, sleep. Then the routine starts again. However, her routine is thrown off when she keeps running into a skeleton, supposedly named Sans. She would like to get to know him more herself, but there's one problem.. He doesn't talk. Of course, Undertale belongs to Toby Fox, not me lol
