    Summary

    Sans knew in his soul that there was only one way he was now in another universe. Erasure was one thing a reset would fix, but corrupting and breaking it would be the only reason he was here now.

    He had expected to overwhelmed in this world of 'kill or be killed' but it was this timeline's version of his brother and himself that had him stepping up. He was a 1 HP monster, physically weak but he did have one thing on his side in a world so filled with LOVE.

    Summary

    Everyone's favorite OT3 (or at least my favorite) and their story.

    Mostly copy/pasted from my Chapter 100 Special of COSOS, but I am thinking of adding NSFW chapters later in the story. We will see.

    Summary

    Life’s hard when your dad’s a drunk and you got four younger siblings to worry about. Between working several odd jobs and attempting to keep all the bills at bay, you rarely have any time for yourself- let alone friends or a relationship. You’re at your wit’s end, but fate seems to have mercy and grace you with several new monsters in your life who are all more than willing to help.

    Summary

    You are (Y/N), an average girl, living an average life with your pet dog you named Growlithe in an average apartment, working in an average fast food restaurant.
    Being awkward and clumsy, you managed not to get a date for years now, which ended in you having instant-crushes on random people that caught your eye.

    Including a dancer you saw in the dark, on the way back home from your shift. You never saw his face but just had to fawn over him.
    And a bassist that lives a few streets across from you.
    And a short skeleton monster that one day appeared at your work with his younger brother you already managed to baffle with your bullshit before.

    Your life used to be the average life of a young adult, but then it turned into the average zombie movie.

    Yep. Zombies.

    Summary

    A BIG collection of ficlets, drabbles, and regular fics about Frisk and Asriel, taking place in my AU of Abovetale. I plan to tell the small stories I never got to, or only hinted at, so expect spoilers not only for the whole Pacifist run of the game, but also for Abovetale. There will be silliness, sappiness, and all of that, so I hope you enjoy!

    Summary

    The first time you jumped from that building you wanted to die. You wanted to go be with people who cared for you. Really cared for you. To step out of this world of agony, and sorrow that would never understand a person like you. Never tried to understand. With nothing left to hold onto in this world you jumped. Then it caught you. You were dazed as you were brought slowly to the ground. Gently even. It was like nothing you ever felt before. Light as air. As soon as it was there though, you felt it dissipate when your feet touched down. Leaving you to walk back home in a daze wondering what had just happened.

    Summary

    You haven't had an easy life. The mistakes you've made have carved literal scars into your mind and body. A precious life was lost because of you. But now you've moved to a new city, trying to leave all that behind you. You've got a promising new internship at the radio station, new chances to start over. The foggy past is behind you.

    And perhaps a bright new future is ahead. You don't know what to expect. Meeting a new family of monsters certainly wasn't even close to what you imagined. A certain pun loving skeleton who seems to have his own share of trauma catches your attention in particular. But can you trust him with your scars?

    Summary

    For Monsterkind, the Surface represented freedom.
    For Frisk, it's a return to some uncomfortable realities.
    It all began with a simple wish. When that wish faded, Frisk tried to move on.
    Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight.
    From an unknown child, they had become an icon of great value.

    'The Golden Quiche'

    What to expect from this story:

    -Mystery Drama
    -Anime
    -Extensive Surface Worldbuilding
    -Expanded History and Backstory
    -Magic System
    -More Magic
    -Both new and old people.
    -Feels.
    -Gambits.

    What to not expect from this story:

    -Toby Canon.
    -Commonly agreed headcanons (about a certain scientist in particular)

    Summary

    Sans disappeared one day with a note on his pillow, leaving you, a teacher at Dreem Elementary, and your son, Crisanto, by yourselves.

    It's been years since you've seen him, having only his quick letter to remember him by. But what happens when others try to help you? When they are willing to risk their lives to bring your husband back? To make your eyes smile as much as your mouth does?

    Please enjoy :)
    (Just putting this out there: although this is a Sans/Reader, it also focuses on your son. Like, a lot.)
