Imagine Undertale, but Chara never showed up. Chara wasn't the first human in the Underground. What if a glitch occurred, and you fell down instead? You fell into the Underground, but you cant remember your previous life. Now, you are surrounded by strange monsters, who have also never seen a human before. Will they let you live? [written 2017]

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.)

[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?

PLEASE READ BEFORE GETTING INTO THE STORY: In a story of Undertale where Monsters are bound to the laws of having a Soul Mate, (Y/n) doesn't understand her own role in this world of deceit and cruelty... not until she meets a certain skeleton. While she is best friends with Frisk, the two trust each other at all times. Although... how far can (Y/n) run from her past? Especially when both her and Frisk are primary targets to it... --- Okay, so an important note. This story will have shorter chapters. Probably around 1500+ words each. Whenever I am unable to preform a larger update for my other story, I will instead do this one. Anyway, I hope that you guys enjoy! Sans will also have a possessive nature in this, fair warning. Also, this is rated mature. So keep that in mind while reading. Also, as all of my stories have gone on thus far... the image DOES belong to me, please do not steal it/ use it without permission! And here are your important key words while reading the story! (Y/n): Your name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color

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.

It's been 5 years since monsters emerged from Mt. Ebott. They integrated into society rather quickly, but they still have people who disagree against the Governments decision to give them rights. Personally, you think monsters have better morals and attitudes than humans do. And who new that all you had to do to gain new friends was to get stabbed in the leg? When your insane brother escapes prison unexpectedly, you never have been happier to have friends who care about you. However, one monsters smile keeps you filled with hope and determination along with something you denied yourself of years ago...

What instead of having a son, Toriel and Asgore had a daughter? A daughter who never died? A daughter named (y/n). Monsters have been locked in the underground for many years now, and their only hope is to collect seven human souls to break the barrier. With six souls in their collection, they're so close to breaking free. ... But what will happen when a certain demonic child by the name of Chara enters the realm of the monsters, and begins slaughtering them off one by one? Will (y/n) be able to save her people? Or, will she be unable to save the ones she cares about most? *** As of 5/9/2018 this story was ranked #18 for 'reader x sans'. As of 6/16/2018 this story was ranked 704 for 'undertale'.

You have a routine; jog, relax, and work. It may seem mundane to most, but for you it's comfortable, easy. It keeps you in your bubble. And you wouldn't change anything about it. That is, until two skeletons move in next door, and you discover that their lifestyle is a less than conventional one, but one you're going to have to learn to live with anyway, for better or for worse.

Not everyone is special enough to know exactly where the Underground's secret entrance is. Not everyone is so special as to accidentally fall into it, either. Of course, that is what the Reader did. They meet the whole gang, and one skeleton in particular stands out from the rest, simply because he's the only one like you. Agh! I'm spoiling the story! Well, if you want to know more, you'll have to read on to find out! As per usual, credit goes to Toby Fox for making Undertale and its characters. Art is not mine, either. OH MY GOSH. #1 in sansxreader?! I CAN'T - I CAN'T EVEN -
