    Summary

    Sans/Reader fluff and angst! And angsty fluff! And romantic fluff!
    Every chapter is its own story!
    Prepare or tears and happiness and other stuff!
    You can read this apart from the first work in this series, but I carry a lot of stuff over from that one, so I'd read it first to make sense of some of this stuff. I really only started a new work because I was worried the other one was getting too long.
    Thank you to everyone who supported me and left kudos on my last work! These are basically 1/4 canon compliant, because most of it is me talking about ships and stuff.
    Anyhoo, you just got back from Colorado, and immediately things start getting weird. How will you and Sans handle it?

    Summary

    * I thought I had warned you about that guy. “Don’t let him find out ANYTHING about you”, sounds familiar? … Oh, but that’s right! I forgot you NEVER listen. To you it was all just a game after all, wasn’t it?
    * Hee hee hee. Let me give you a little tip then: the Game is a Lie.


    * Echo Flowers repeat what they hear, babbling back and forth to each other until their words become meaningless noise.
    * What used to be the “truth”… soon becomes too distorted to appeal to anything you thought you knew.
    * Never trust a flower. That’s one of the constants of this world.


    After trying everything he could to stop time loops from ruining his life and universe, Sans has finally figured out the truth. As a last resort, he finds out that he has no more choice… but to ask for help.
    May 1st, 2016. Undertale has existed for half a year, and its fandom is raging at its full potential. But then, a Player disappears.

    Summary

    Ten years have passed since monsters left the underground. As Frisk prepares to begin college, Sans faces questions about meaning, motivation, and when it's worth getting back in the game.

    (Or: the one in which Sans goes back to grad school . . . eventually.)

    Summary

    When Frisk fell into the Underground, it wasn't just them that gave the monsters hope. Another human on the surface gave them hope alongside the kid. Together, the two freed the monsters and helped them adjust to life making friends and a new family over the couple of months they've been on the surface. Will monsters find a special kind of love in a very special human? Will they get hurt proving themselves worthy? Would they sacrifice their lives to protect them?

    Summary

    “My name is Connor. Don’t worry, I’m not a—”

    “HUMAN!”

    Connor audibly groans. Even as he knows he’ll be pursued soon if he isn’t already, he takes a moment to pinch the bridge of his nose, then looks back. The logical thing to do would be start preemptively running. Instead, he glances back and shouts, “Android, actually!”

    An energy spear shoots through the air, passing not an inch away from his face and lodging itself in the wall nearby. Judging by that, and the angry yelling coming from its thrower, Connor decides it may be a good time to run.


    Humans and androids have found themselves in an uneasy peace, although that’s not to say there isn’t still a long way to go. Then Connor’s asked to investigate a site where humans have been disappearing for a very long time. And, suddenly, everything’s a lot more complicated.

    Of course, Connor’s the only one who knows just how complicated things are now, and he’s got slightly bigger problems at the moment. Like staying alive, and one step ahead of the monsters that want to steal his apparently very human soul.

    Summary

    On the one-year anniversary of the day Frisk freed monster-kind from the dim tunnels of the Underground, something unimaginable happens: the world resets.
    Devastated, Frisk faces a challenge harder than her initial run through an unknown world as she races to find a way to prevent the same tragedy from replaying after Just One Year.

    Summary

    You run a little music shop in the town of Ebott - yes, a town in the shadow of that particular Mt. Ebott where monsters first appeared. It has been eight years since monsters first came to the surface, and Ebott Town is as welcoming as ever. How could it not be when all these new monsters want to do is see the sun, see the stars, and play some music?

    It's a day like any other when two skeletal monsters walk into the music shop you and your father maintain - the shorter needs his bass repaired. Cue laughter, puns, shop kitties, and the start to an epic adventure as you meet the gang and help them on a journey to get their little band into a big Battle of the Bands that will end with the winner scoring a great record deal. Frisk needs encouragement, Undyne is enthusiastic, Papyrus kills it on percussion, and Alphys supports behind the scenes as the sound tech.

    Updates bi-weekly, hopefully. I work theater and I'm in college, so gods only know.

    Summary

    We have our happy ending, so the end! Right? Frisk, human ambassador for monster kind, has many unanswered questions about what happened underground and has a funny feeling that their new friend (a perfect stranger) has the answers. Sans, however, doesn't think that's a good idea.
    *Hint, hint: There's more to the story than the summary foretells.

    Summary

    Ebott City, 191X. Fresh from university, Doctor Sans Gaster is ready to become an alienist. He studied hard, knows his facts, but lacks the experience that should go with it. Now working as an apprentice at Ebott City’s lunatic asylum, things are not going as he imagined. For what is insanity? What is madness? What is good? What is evil? Since meeting Frisk, everything he knew changes.

    Summary

    As a lonely skeleton living in New Home by yourself, it was inevitable that this would happen.

    You're sick, with only a few months left to live, if anything your doctor says is to be trusted.

    So you go back home to visit your brothers, Sans and Papyrus.

    Except... things are weird.

    There's a human. And Sans is acting odd.

    Summary

    What if there was an... unexpected reason to why you never hear Frisk talking? What if one little decision changed it all?

    A story of one betrayal causing a predetermined outcome.

    At least, that's what people think. But don't worry, that is but a good premise for the adventure to come.

    "okay, so there's train tracks, right?"

    "Uh huh."

    "and at different points, the trains can go to off from a main track to other ones."

    "Okay."

    "now there's a train that goes down the main track. with every branch off, a cart from the main train goes down it. The main train continues down the track, but isn't aware of the other tracks and the carts moving by them, getting closer. the carts then merge back on the main track, ramming into each other and the train."

    "...That was a very complicated way to say the multiverses are collapsing into a main time-line."

    Summary

    "... As Error followed Ink to their class which was Magic with Mr. Flowey, as he watched ink he thought about why he hated him. There wasn't really anything to hate ink about except the fact that he was absolutely perfect. Suddenly he coughed his such harshness that everyone stared at him worrily he felt something fall out of his mouth and felt warm liquid drip down his jawline, gasps were heard everywhere as Error looked down. He saw his blood and several black glitching flowers. "Oh N-No" he said with weakness in his voice. He was in love...."

    Summary

    Monsters have arisen from the depths of Mount Ebbot, from a horrendous place you now know as Underfell. The monsters you have the pleasure of meeting may be rough and stand-offish at first, but once you take the time to know them, you're like one of the (albeit dysfunctional) family!

    Summary

    Occasionally as the team works towards their ultimate goal of freeing monsters from the Underground for good, they need time to relax. And sometimes, Mettaton, the Underground's biggest (and currently only) star needs a break from his job. When both of these issues crash into each other, late-night crack-filled goodness is the result.

    This is technically still set in my normal universe, but not in any time near where I currently am writing and not for a long time to come. I still wanted to write these and I hope they are at least moderately funny.

    Summary

    You can remove the batteries from every clock on Earth and still time ticks on. You can roll a thousand dice and never predict the direction you’ll be pulled. But time does not define space, probability does not command possibility, and the world spins a little slower when you share the view.
