This story is choice based. Whatever happens in every chapter is based off your choice.
There are no Saves,Resets.
so if you die within the chapters.
you DIE.
don't worry but I will allow different seasons if you die in season 1.
each season will be different.
The reader will be gender neutral and will have different relationships.
(yes it's not only sans you sinners)
I will only do fluff but if requested enough I will do a lemon in one of the chapters.

Anomalies ( Female Chara X Male Reader Sequel) [CANCELED]
•Yeah this thing has been cancelled. Kinda sad for my first book to end up like this but I do intend on remaking this book one day with it's original lore. That ain't coming any time soon though. Anomilies these things are rare to happen but when the code is infected it can make these chances increase, after the last Timeline was Reset you forgot everything bringing you and Chara back to square one somethings have changed but someone especially hates youComplete

He knows of the powers you gained from his experiments... all but one, this one allows you to tear realities just enough to teleport into them. Knowing of Undertale you felt bad for the monsters stuck below in their world and wish to help them, but something goes wrong and you end up going to certain AUs and helping them, gaining the attention of some bad skeletons who now desire your power for them-selfish-selfs.Complete
FriskXSans: Getting Frisky.
Frisk has freed all the monsters from the underground; this story takes place a few years later. By this time Frisk is living with Sans and Papyrus. Sans doesn't really do much on the surface other than sleep, keep an eye socket on Frisk and occasionally visit Alphys...so it seems. Frisk is preferably a girl in this world but I will use words such as: they, them, their, etc. If you prefer they be a male. *Oh man, okay! So this will be my very first story ever anywhere so bear with me if it is rough around the edges. Thank you and enjoy!* Feedback is also appreciated. Please note that I do not own any of these characters, they are owned by Toby Fox.
