    Summary

    You were a young artist.....well, that's what you said you were. You really just stay home all day, make comics online, and draw commissions for a bit of cash. But when the monsters come out of Mount Ebbot, you find that your harmless comics are a little more real than you thought.

    Summary

    i used to be a rather carefree kid just wandering about in school and never really sure what to do with my life.
    - Until a bunch of my friends fell down this giant hole in front of my eyes.
    - And i followed them into the hole.
    Then my life basically took a sharp turn and went completely off-track.
    The problem is, since my life is so off-track, i'm still not sure what i should be doing with my life.

    --
    Basically this author decides to stuff everything interesting they come up with here. Lots of unexplored topics, crazy but somewhat logical ideas, and rambling. Please check Author's Notes for more information regarding updates, bug fixes, edits, etc. Boring first chapter. Unlabelled illustrations by Echo0Faws.
    Special thanks to Kitty_NightLight (Kitty), who's basically the secondary producer and one of the largest supporters. Half the views are probably from her.

    Summary

    ( This is the third book to Sans' House Guests, you should go read that and Shadows of Remorse before you read this because you will be confused on what the heck is happening! This is an original crossover story between Undertale and CreepyPasta where Sans is the main character and makes some CreepyPasta friends! I own neither UnderTale or CreepyPasta, I just own this story and crossover idea! )

    17 years.

    It's been 17 years since Sans had last been heard from, and his old friends and family have grown to accept that he wasn't coming back. They made their mistakes, they pushed Sans out of their lives. It was only fair that he lived his on his own accord. And if Sans didn't want Papyrus to be included in that life, then that was fair.

    But it doesn't look like either have a choice when their lives clash again.

    Summary

    Accountable? Accountable?!
    "let's stop pretending for a moment that you're actually human." Sans said dangerously. "even if i don't remember, i know what you are. you... human? heh. no, kid, you... you are a demon. those red eyes from my nightmares. your twisted smile. you're a freak. a freak and a demon."
    So yeah. He'll hold 'em accountable.
    "just this once."
    Just this once they won't be above consequences.

    Summary

    You've just moved into the city to be closer to work. Everything is going great, when you meet a pair of skeleton brothers, one of whom is tall and soft spoken...and injured and bleeding in an alleyway. And to thank you for driving him back home to tend to his injuries, he's taking you to dinner?

    Things progress to the point you think you know Papyrus pretty well, except, you don't. What kind of secrets is he hiding? For one, he has more in common with you than you think.

    Summary

    You've hit rock bottom, or perhaps hell's bottom. You are now surrounded by hordes of lustful monsters that crave to woo humans into their beds, for the chance to take their virginity is sought after, like a one of a kind rare gem.

    Though the creatures of the underground treat you with respect, like a royal princess, it doesn't stop them from trying to take advantage of you, nor being bribed or sweet talked into submission. The worst of them is a tall lanky skeleton who laughs oddly. He vows to have you one way or another, even if it kills him. He has to, if he wants to reach his life long dream. But he wants his cake and eat it too, for he soon after wants you to fall for him as well.

    What are you to do? Is there any chance of escape? What risk do you take? And how far are you from becoming a fallen human? Just what will become of you then?

    Summary

    It's been a year since monsters first moved to the surface, and things are going relatively well, everything considered; even after their human ally, the one who freed them, suddenly chose to leave and go on their own path, they've found a way to make a name for themselves, more or less. There's just a small problem...

    Frisk has gone missing. Even though they hadn't been directly influencing the monsters' integration with humans, they'd been at least a portion of it, simply because they still supported them in some ways. Without that, monsterkind doesn't have much to go off of, unless they're somehow able to convince the humans on their own.

    It could be worse. It could also be better. It seems it always could be better, really.

    Even so... Papyrus isn't willing to give up so easily.

    Summary

    You wake up, and you don't know where you are. You don't know who you are, or why you're here. You don't know these people...

    And you most certainly don't know who he is.

    There is one thing you do remember, though; and only one thought is clear in your mind:

    Above all else,

    you need to find your sister.

    You pass away abruptly, and you manage to lose everything.
    Then you're thrusted into another body, into another life.

    Summary

And why is this pitiful human he somehow made friends with through his glaring, so open to help him when his brother isn't? He just wanted to go home where everything was just a little bit simpler.

Well clearly after they recover from their injuries they're going to have to be re-introduced to each other!

    Summary

    Ever wonder what might happen if someone from the fandom who knows way too much about Undertale were to suddenly end up in the world they've been obsessed with for years?
    Huh... me too. :3
    Just a heads up, this isn't a standard Isekai fanfic, there are fantastical elements that carry over from the transported character's home world for added flavor.
