Long after the events of the great war between humans and monsters, a young human girl becomes an unwilling participant in a sinister crime against nature, having her soul become fused with the souls of two others and thus altering the fabric of hers. Little does she know that the other souls belonged to humans that were reincarnated; one into an angel, and the other into a devil. An unusual twist complicates their already precarious situation, as only one can manifest into existence at a time. 

It is said that these girls, dubbed as the Soul Sisters, hold the fate of the monsters in their hands. Will they bring harmony and peace? Or will the fractured soul they share become a catalyst for their destruction?
*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*
This book follows the tale of a brand-new Undertale AU known as TripolarTale! It follows the story of Ember, a devil who has unwillingly been transported into the Underground after her soul, which had originally been stolen, has fused with the souls of two others. Join her on her journey as you wonder, which side will she choose?

This story takes the characters and elements of both the base game Undertale and famous fangame Undertale Yellow!

I hope you enjoy this take on my new AU!

(DISCONTINUED) 'A young girl has just been living her life normally; until she turned thirteen--the age where you can find your soulmate. That was when this young girl and their parents--found out that her eyes not only changed colour, but she also had a tattoo/soulmark.' 'For years humans have been born with the ability to find their soulmates by eye colour. The first emotion you feel when you turn thirteen is the emotion that causes your eyes to change to your soulmate's.' 'Monsters have been able to find their soulmates by a tattoo of something that represents their soulmate. Humans, however, do not have tattoos unless they are a monster's soulmate. If this is the case, the 'soulmark' as it is referred to as, will only represent the monster soulmate and will be the single soulmark used to find the other half. A monster can find their soulmate by either of them touching the other's soulmark without having any bandage or piece of cloth in between them. Although rare, it is not uncommon for a monster to have a human for a soulmate--so what if Sans did?' WARNING!: This was a basic summary, I will be adding in a bit more information! Although this IS an 'X-Reader' fanfic, (and my first at writing one) I will be giving the reader heterochromia eyes. You will be able to choose what the colour of her right eye is--but for the sake of this story, her left eye will be green. 1st Book in a Series! AND YESS, the reader will be female. (Sorry guys!!!) I Do Not own Undertale, it is owned by Toby Fox! I do not own 'reader,' you do. (The cover art is the soulmark.)

It was just a normal Saturday. (Y/N) was playing Undertale for the millionth time. She was obsessed. (Y/N) had played all of the routes. True Pacifist, No Mercy/Genocide, Neutral. She experimented with killing certain characters doing different things. Then, as (Y/N) started a new game, she felt a falling sensation, as if she just fell out of her chair. She blacked out soon after. When she woke up, she was lying on a bed of golden flowers. She knew this place. (Y/N) was in the game. She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself. I do not own the cover or any of the pictures that will show up in this book• *If you're reading this as a guy please just change the pronouns to he/him/his.
