Y/N is an Ultima but she is also a soul mix. A soul mix is when two soul types combine and become one being. She is a mix of CHAOS and CORRUPTION. The strongest soul types other than Determination and Fear. Y/N was used as a weapon in a war. The Children's war to be exact. She has become emotionally drained since then. She hopes that the bitties will help her become more emotionally active. And they do...

OLD AND BADLY WRITTEN THE REWRITE IS POSTED ALREADY DISCLAIMER: The god figure created in this fanfic is purely fictional. He is purposefully made to be prideful and cruel and is not supposed to represent any god. I am religious myself and I did not intend to attack anyones believes with this book. An angel. Sign of hope for humans, yet a nightmare for monsters. Powerful, skilled and...beautiful. But what happens when one rebels against the cruelty towards monsters? What happens when she's banished to the underground, only with wings as a painful reminder of who she once was. What if she's found by the Royal Scientist? What if the nightmare every monster is scared about, is just as broken as they are? And what if she'd find something she would never imagine she'd find in the underground...love? *Cover edited by me. The pictures used in the story belong to their original creators. If any of them aren't okay with them being used, I'll take them down* Started: 21.12.2018 Ended: 22.08.2021 09.03.2019-Number 1 in gaster! 07.02.2020- Number 7 in undertale! 25.02.2020- Number 4 in undertale! 15.04.2020- Number 1 in undertale! 11.10.2020- Number 1 in papyrus! 03.06.2021- Number 80 in fanfiction!

I made this book for @KawiiPotao6678 they have never read a flowerfell x reader so I made this book for them. But all you other people can enjoy as well. Sorry if some of the information on here is wrong I am not very familiar with the Flowerfell AU. I will look up what I can and learn more about it while making it. I will also fix what mistakes I have made because some people are so picky about spelling (not saying any names). I own nothing but the story!!!!!!!! I don't own you!!!!!!!!! I don't own undertale!!!!!!!!! I don't own Flowerfell!!!!!!!!!!! Nothing is mine!!!!!!!!!!!!!

Now on the surface, Grillby re opened his bar. New and old faces poured in each day. One recognizable face was the pun loving skeleton Sans. After meeting a strange woman, they are given job offers that they simply cannot refuse. Literally. I absolutely hated my original story, so I re-wrote it here. The story line and characters will be the same, but this is the better version, in my opinion. ⚠️ Warning ⚠️ IN THIS BOOK THERE MAY BE KIDNAPPING, SUICIDE, MURDER, DEPRESSION, PTSD, CURSING, SMUT AND OTHER MATTERS OF THIS KIND. IF THIS DISTURBS YOU PLEASE AVOID THIS BOOK. THANK YOU All Art is not mine, Characters belong to Toby Fox, and I hope you enjoy the story. P.S a creator by the name of @jaide_lightbones created this beautiful cover. You should go check them out! Okay, now enjoy your read!

You always enjoyed watching your big sister perform since a young age. As you both got older, something in her was starting to change. She was more sharp tongued, cruel even when she spoke to you. One day she even got a gig to sing with a small group at the local popular bar Grillby's. Long story short she walks out, and you, being kindhearted as you are couldn't leave them to struggle. Dressed up, you sang with the group. Eyes scanning the crowd spotting a skeleton that just couldn't take his eyes off you at the bar. Once your eyes locked something stirs inside of you. Was it a good or bad thing?

Ever since you were little, you dreamed of being on stage and dancing to your hearts content. You were determined to get where you wanted. All spot lights on you, people cheering and clapping as your feet swept across the stage. You were so close. 1 day away and you would have all of your dreams come true. Then everything was lost when the plane you was on crashed. You lost all feeling in your legs and lower body. So now, instead of living up to your dream you promised yourself would come true, you watch from a balcony. Instead of dancing like you wanted to, you got the complete opposite. Now all you can do is watch the monsters dance on what was to be your stage. ---- "You can dance. I can cry." "So let's make a tear jerking performance." ----
