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 -

My first story. It's a sans x reader fic, so don't judge too harshly. Also I have some bad pacing issues, but I hope yall will ignore them. Anyways on with the summary! You see monsters everywhere. All of theme unique and friendly. You ask "how could anyone hate them?" When you save one of them, you're life takes a drastic turn.....for the better. Highest rank: #16 in Undertale (June 2020)

Hiya! This is going to be my first fan fiction. I have recently been obsessing over undertale, and sans is my favorite character. I have already read a lot of sans x reader and decided that's what I wanted to write. I don't know how long this story is gonna be or how often ill update, but ill see how it goes and if you guys like it I might do more in the future. XD wish me luck! Ps. I do NOT own any artwork that may be used.

You woke up and tried to gaze around the darkened room, your vision was blurry. It was just a bad dream, you thought. Your eyes adjusted and you realized it was far from it... {Completed} Thanks so much for 300+ votes & 10k+ reads, holy heck.

Monsters have returned! (Y/N) is waisting no time to find out more! After running into a hyper skeleton twice you slowly start meeting and growing attached to a new group of monster friends. One however is more likeable then you thought. (This is Sans x Female reader)

The monsters have finally made it to the surface and have been legalized to roam the surface as they please. The first couple of months have been spent as a paradise where humans and monsters have lived in peace and happiness. But as we all know, humans tend to be afraid of what they don't understand and the appearance of the monsters only seemed to have fueled the rising tension. You are a member of one of the biggest clubs that support the monster's appearance, known as the FMC (For Monsters Corporation). There is a rival club, known as the DM (Destroy the Monsters) that only wants to exterminate the existence of the monsters, and with every passing day, conditions only seem to be getting worse. Determined, you try to make things right and equal for all beings, but things start to alter when you meet with a certain skeleton. And with this certain skeleton, you, dear reader, reveal your biggest, most valuable secret...your little "defect". •°•°•°•°•°•°•°•°•°•°•°•°•°•°•°• COVER ART IS NOT MINE, I ONLY EDITED IT OUT FOR MY COVER. UNDERTALE DOES NOT BELONG TO ME, IT BELONGS TO TOBY FOX. I am simply writing this for the sake of my imagination, as well as for the entertainment of others. Thank you.

//Undertale High School AU. Your typical High School story where you're the new girl~ //Except monsters and humans are together too. Involves time travel in later chapters. Never wrote an Reader insert before, so spare me! "You look lost there, Kiddo." A deep smooth voice caught your attention and you turned your head, facing a short Skeleton in a fluffy blue winter jacket. "Oh, U-Uh, Yes." You stammered, looking down at your shoes. "Don't need to be shy." He chuckled lightly. "I'll show you around."

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.

You climbed the famous Mt. Ebott to prove to a group of your friends that humans don't disappear when they go up the mountain. While walking around the peak, you trip over a root in the ground and fall forward, expecting to hit the ground. Instead, you were met with open air. As you fell down the large hole, you let out a shrill scream before hitting the ground and blacking out. When you wake up, you find yourself in the Underground where monsters had been banished to by the humans. You meet several monsters down in the Underground, some becoming friends and some becoming enemies. One particular monster though, has been making your heart flutter and your tongue get tied. Sans the skeleton. A new threat appears when a human that had been thought to be dead comes back and threatens you and the entire Underground. Will you be able to stop them or will you be used as a puppet and watch your friends die? Maybe the only thing that can defeat LOVE is love... Author's Note: this was my very first story so sorry if there's bad grammar or confusing scenes, enjoy my awful writing! ((COVER ART IS NOT MINE))

The old bookstore wasn't your home anymore, you finally realized. It was with them. It was with him. (Sans (Undertale)/Reader. The story takes place in second person view. Reader is not Frisk!) (art is by @Elmer_Heiji on twitter)
