When a demon summoning goes wrong, a rich and powerful man's son gets killed and (Y/n) is forced to team up with the Demon King that did it to survive the ensuing attempts on her and her family's lives. But the King will only do it on one condition: he gets her soul. So with no choice but to die for her mistake, His Summoner promises him her soul when the job is done. | - Demon! Nightmare Sans x Female Reader - A little bit of a reverse harem with plenty of Bad Sanses x Reader moments (with a canon reason for it :D), but ultimately, (Y/n) is Nightmare's - Honestly you could read this with no prior knowledge of any of the characters and you'd be just fine - Kinda a slow burn? But don't worry, I throw in so many subtle/not-so-subtle intimate moments with all the Sanses that it makes it worth the wait :D - I'll throw in some bonus chapters with the other Sanses for extra (non-canon) fluff that doubles as a breather from the story, too - Is the relationship toxic? Maybe. I mean, this is canon Nightmare after all. But that's the beauty of a fictional story, no? - A lot of the symbolism and hidden meanings aren't obvious, so you might have to be on the lookout to see them (and keep in mind: Night doesn't openly show many emotions, so the devil is in the details) - I'm not going to spoil anything, but for all you anxious readers out there like me, I'll divulge I'm a sucker for happy endings *wink* - It's my interpretation of the characters (kept as canon as possible)

Y/N, 5 year old, was found in a collapsed AU that just wouldn't be erased from existence. The bad guys found them and took them in as their own. Who knew taking care of a child was so difficult

An endless cycle of positivity and negativity that clashes within the Multiverse, ignorant of the AU they once called home... Ignorant of the little sister they'd forgotten was family.

It has been 10 years since the monster broke free from the barrier, and since then monsters and humans live together in peace. But for some reason, monsters have somehow got a mini version of themselves, no one knows how or why it just happened. And for some reason, the skeleton bittys are popular because of their many different versions. You are a 19-year-old girl who lives in New York City in your apartment the problem is that you're all alone( if you're wondering if your family is alive, you just live far away from them), you have a small dislike for people. You wish you could get a Bitty to hang out with it, but the problem is that it costs a good amount of money. So you could never get one or so you thought until one day you find a strange box. This is my first time posting here so I hope you enjoy it! Also note there is some swearing. Note the cover does not belong to me. It came from https://undertale-au-fanon.fandom.com/wiki/Bitty!_Sanses By The Edit Lord Also I do not own any of the characters. Undertale belongs to Toby Fox.

You didn't have a bucket list or anything, but you wished you could've at least read a few more fanfics or done literally anything fun before dying. Oh well, at least you didn't have to socialize- Wait. Since when did dying mean becoming a doll in an Undertale multiverse? How did this happen?? This was inspired by a ton of reborn and reincarnated as Undertale characters fanfics and some other awesome stories! The main inspiration was 'Little Dream Doll' by KassyxTheDumbFox, and they got the idea from Firehedgehog's 'Idea Factory'. Beware, this story is fan fiction and is not canon, will include ooc characters, and I don't own Undertale or any of the characters, if you don't like that please read something else. This is my first story so there's no guarantee I will update regularly if at all, this is mostly self-indulgent. Btw, the cover's mine, please don't use it.

Basically the reader is either a Bitty, baby, young child, borrower, or Sans is super big. The reader is almost always some type of mythical creature, from different cultures. Ex: Kitsune- Japanese, Cerberus- Mainly Greek, and etc. REQUESTS ARE CURRENTLY CLOSED (All images used do not belong to me unless stated otherwise.)
