Welcome everyone! To another fan-fiction book!! This book still contains your beloved characters from the game and a few new others. Good luck reading, and HAVE FUN!!
(P.S. If you do not know the game, it's fine. I'll make sure to write important information.)
This story takes place after the events of the pacifist ending of Undertale, where all the monsters have already left the underground. However, that won't stop problems from starting again; Frisk and his friends will have to face a new threat.
DISCLAIMER: This story is based on the fact that the first human fell underground in 2015 and the last in 2060. Here, Deltarune is a sequel to Undertale; therefore, Posttale is not a copy of TobyFox's creation, but an adaptation, or what is also called an "AU."
Because of this, there will be things that are different from canon and adapted to my personal preference, with no intention of disrespecting anyone; for example, the gender of the humans:
Kris: M
Chara: F
Frisk: M
Don't like it? You can leave.
Understood? Great.
