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)

The war between the two guardian rulers and their kingdoms lasted for countless generations. Then came the news that Nightmare went ahead and got himself some new "friends".. Dream's soldiers were easily overpowered. Battles were being lost and the shadows began to completely overpower the sunlight's rays. With the scale of life's balance beginning to tip, Dream needed a quick solution.. The King needed a Queen. The arranged marriage would spread positivity and hope throughout his entire kingdom. Maybe, just maybe, it would give them the boost they needed to defeat Nightmare once and for all. Hi, it's Writer~San aka OreoDaSkeleton! Undertale and it's aus, characters, and fanart do not belong to me. However, this story is genuine and 100% mine! Thanks for checking it out! -w-

Do you love Sans? How about the numerous AU versions of him? Of course you do, that's why you're reading this. So if you're looking for some X Reader oneshots with your favorite Sans, I might be able to sate that craving.

I DO NOT OWN THE COVER MAJOR BACKSTORY ELEMENTS ARE DERIVED FROM SOMEONE ELSES TIMELINE THROUGH THE COMIC "HANDPLATES", COMIC DUBS AVAILABLE ON YOUTUBE, NOT BY ME, RECOMMNEDED IF YOU ENJOY UNDERTALE AS A WHOLE. **TW** THIS X READER CONTAINS SEX, VIOLENCE, SELF-HARM AND SUICIDAL THOUGHTS. IF ANY OF THIS TRIGGERS YOU, PLEASE DO NOT CONTINUE. I couldn't take it anymore... I wanted to end my life. She's dead now and I didn't have it in me to help... Watching helplessly as her body drained of blood... That night, I decided. I'd run to the only place that I held good memories of. That we held memories of... I would end my life in the only place I remember being happy... Mt. Ebott...

Want to talk about falling into the wrong place at the wrong time? Y/N definitely scored big time on that one. One moment she's falling, the next she finds herself trapped underground with a monster that wiped out his own kind. He's a cold-blooded killer that never shows any emotion. Though, as time passes, she finds out that Sans isn't as heartless as he plays himself to be. Hello! Writer~San here! Cover art and Undertale AU/Characters aren't mine, but the story definitely is. I hope you enjoy it!!!!

what happens when you know the story of the to dream brothers and you have a chance to stop there faint, will you change it or will everything stay the same.

PLEASE READ BEFORE GETTING INTO THE STORY Description: Your name is (Y/n) and you are originally from an au called Dreamtale! Your life hadn't been the easiest however, but you were quick to always move forward despite this... Before Nightmare had become corrupted, you were his best friend and lover. You kept him from his breaking point, you maintained his sanity and most importantly... returned his love. One thing that is definitely important about yourself is that you are a selective mute... And your only desired partner for conversation is the King of Negativity himself... But what will happen once the true evil lurking within your lover drowns out whatever light he had left? What will happen when you discover that the Nightmare you knew was replaced by a monster that still somehow holds love for you? "And even with the evil finally in control of Nightmare, if both his sinister side and his old self agreed on something- then it would always be his priority... They both love her." This is practically my first story that I have ever decided to share online. It is quite a terrifying experience for me, so I hope that anyone who decides to read this will enjoy it. Anyway, I should probably inform my readers about a few things. First off, my primary language is not English, however, I will still be making an effort with my grammar! Second off, I will try and update this as frequently as possible... Even though I can get somewhat shy or concerned about how my work goes. Otherwise, all you will need to know is this: (Y/n): Your name (F/n): Friend name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color Some things I will likely determine for the reader, but what is posted above will be the basics. Please also note that this story may contain some content that would be best for more mature audiences. Also, the cover image belongs to me, please do not use it without permission or steal it.

You have a twisted life, and you're in an orphanage because you're parents died in a terrible car accident...or at least that's what everyone says. You go to this annoying school called Pinecrest High. Everyday, you go to a tree to help you with your nerves. And one day, a certain skeleton saves you from certain doom. Yes, this is an X Reader story. This story updates slowly and I need lots of time to think about the plot points. I'll change the story summary when the book is finished to make more sense. Just please enjoy the story :3
