Note:This will be a fanfic about the True pacifist ending of undertale.However,some characters will either be my OC or OCs by others who I will credit.All other rights of the characters go to the creator of the game,Toby Fox.Also this will contain major spoilers for the game so don't read if you do not wish to be spoiled.And lastly,a lot of the content is my personal headcanon,like the genders of the fallen children,so do not take what is said here as confirmed by the game.
