    Summary

    How, then, does one define a ‘soul’? Is it developed over one’s lifetime or the moment they are born? Are some naturally evil, rotten from their very core, or is such a thing learned? Does it have something to do with genetics? A difference between blood and magic?

    How do people grasp the idea of what makes them themselves when such an idea is easily discarded?

    OR -- the AU in which a monster absorbs a human soul and the consequences that come from messing with the continuity of the multiverse.

    (ANOMALYTALE is a mix of previous ideas/AU's ive messed around with over the years, including my old & abandoned au, devastationtale. some chapters may be unsuited for certain people, so please make sure to read tags/warnings before you read! hope you enjoy!)

    Summary

    Frisk grew up in a home with neglectful, drug using parents. With a little sister to take care of, Frisk goes to Mt. Ebott to collect a flower specimen for a professor in town who was willing to pay three hundred dollars for it. When she falls into the Underground, she finds danger, but also family and friendship. With the help of a mysterious ghost girl named Chara who only she can see and who she shares a connection with, as well as some new friends, especially a certain pair of skeleton brothers, Frisk tries to get back home to her sister, but what will be the cost? And how far will Frisk go to protect both her sister and her new friends?

    Summary

    After his timeline was destroyed along with almost everyone in it, the Sans who would come to be known as ‘Blue’ had an epiphany.

    Everything sucked. Like, all the time.

    It was not, perhaps, a new discovery, but it was the first time he had admitted it to himself. He had always tried to keep a positive attitude in life, even if his recent circumstances had put a sizable dent in his motivation.

    But still, he wouldn’t give up! As long as there were still monsters out there who could use his help, Blue would never give up.

    And so, stuck traveling the multiverse with a child and stuffed toy that were doing their best to kill him at every turn, Blue attempted to help prevent other universes from meeting the same fate as his - and perhaps make some new friends along the way!

    After all, just because life is hell doesn’t mean that he shouldn’t be cheerful about it!

    (in which Underswap Sans survives a no-mercy timeline unlike any other, and ends up losing both his home and his ability to Be Chill™.)

    Summary

    "There she is!" I hear an excited voice shout.

    This would be a fan of mine. And all of her friends are now running towards me. You know I love my fans, really I do, but I hate this kind of fan. The kind that reached for my mask. The kind that didn't want my identity to stay a secret.

    Just before a girls out stretched hand could grab the family heirloom that covered my face I turn and take off down the street.

    This was just my luck.

    (This is a Sans x Reader fanfiction where the reader is a Musician. She hides her identity with a mask. More information in the Prologue.)

    Summary

    When circumstances find Chara and Sans alone together in the house...

     

    ...Well, it's a little more than awkward.

     

    ...Making peace is hard, ok?

    A bit darker than my previous two fics. Please read the tags and the author's note, I don't want to upset anybody.

    Summary

    Sans counted to 10 in his head before using his magic to force open the door.

    And...

    He knew if he had to breathe he would have had trouble doing so at that moment.

    Summary

    At the time that I wrote this, it was to vent some frustration at myself for how I acted and felt in a lot of social situations, so it kinda reflects that. There's no actual romance between Reader and Sans, unfortunately. There are mentions of Reader previously having a crush on him, however. If a long, sad, pity-party fest is your sort of thing, go for it.

    Reader is Chara.
    Mentions of self harm.
    Slight violence? Mentions of blood and bruises.

    Summary

    Sans has apparently dropped out of the royal guard! It seems like he wants to help the human on their journey. It's questionable for all the monsters in the underground, for why a monster should HELP a human. When all they need is a soul to be free, the last soul, that is.

    Summary

    A three-year anniversary, one-shot sequel to Strange Places. "But Ayu, you're a day late!" Shhh. Spoilers for that story, and also in general, abound.

    Chara is having a bad brain day and has sentenced themself to a quiet night indoors to keep from ruining anyone else’s fun. When Sans shows up, maybe to keep them company, maybe because someone asked him to keep an eye on them, maybe just to be annoying, they end up asking something they’ve been wondering for a while now: what exactly was Gaster to him?

    Summary

    Trust takes time.
    Forgiveness takes longer.

    ---

    There are some wounds that run deeper than can be healed, and there are some conversations that can be dangerous to have, but both of them have a door at their backs and a lot of mutually achieved wounds. And if you can't talk about hell with someone who kept you there, then who can you talk about it with?

    Summary

    A skateboarding stunt goes wrong and Chara is taken to Dr. Gaster's office to get her broken ankle set. She's afraid of doctors, but a small punny skeleton who barged in on her appointment to bring his father his lunch might be just the distraction she needs to help her get over her fear.

    This is the story on how Sans and Chara became friends in the As Sweet As Chocolate Nice Cream series.

    Set in a universe where Asriel stopped Chara from going through with the buttercup plan. This is a sequel to A Twist in Fate: Saving Chara, but can be read alone.
