You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

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)

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 life. | Set in the same demonic skeleton universe as my demon Nightmare book with a different story, it's my take on the simple question: ''What if (Y/n) summoned Dream instead of Nightmare?'' | - Demon! Dream Sans x Female Reader - Alternate Timeline of ''His Summoner || Demon! Nightmare x Reader'' (but you don't need to read HS in order to understand Her Guardian!) - Dream has his own version of denial so it'll be a slow-ish burn again - Honestly you could read this with no prior knowledge of any of the characters and you'd be just fine - It'll be a reverse harem again (kinda), and I'll throw in some bonus chapters with the other Sanses for extra (non-canon) fluff that doubles as a breather from the story - Some characters get some much needed therapy (*cough* Dream) as well as more trauma✨(I don't eff around, and to prove it, characters will die) - A lot of the symbolism and hidden meanings aren't obvious, so you might have to be on the lookout to see them (though I think I was a little more blunt this time around?) - It's my interpretation of the characters (kept as canon as possible)

[THIS IS A SEQUEL TO MY OTHER FANFIC "WHEN TWO SOULS MEET!" If you haven't read it, I would highly suggest it--the story won't make much sense otherwise.] Sans has finally found someone he can trust--Frisk's sister, the eighth fallen human. After months of step-siding and awkward interactions, the two are finally a couple. Things are finally falling into place--there are no more resets, and Chara and Flowey have been a lot more quiet in the last few months. But things can't stay this way... can they?

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister. Please note the the story is primarily on Quotev, so updates to Wattpad may be late, or lag behind that of Quotev. The story also has the potential to become mature. (I haven't decided yet.)
