    Summary

    You're a mostly shy and ill-mannered girl endlessly blaming the world for something you yourself aren't quite sure of. You hate that you're stuck being unhappy while the rest of society- monsters and humans alike- stroll along with their happy lives, unaware of your miserable state of dependancy. You envy others for their tenacity to survive the world when you can't...

    Everything changes when you meet a tall skeleton monster with artisan spaghetti dreams, an anime-loving fish monster, and her much shorter lizard-monster girlfriend obsessed with Mew Mew Kissy Cutie. Can the three find a way to change your stone cold heart and bring you out of your monster-bigoted mindset? Or will you fall victim to living the same lonely life you've lived since the beginning?

    On top of that, will a pun-loving skeleton still wary of this reality vanishing help you out with his friends? Or will he be the one to push you over the edge into misfortune?

    WARNING: Reader is not a nice person in the beginning, and that is intentional. You will cringe. You will scream at the computer. Some characters may seem out of character, but that's intentional as well.

    REALLY Slow burn! Hate-love!

    You're going to have to learn how to deal with it.

    Summary

    Standing on the edge of a waterfall, you contemplate your life and what brought you to this point. You had always been told that obeying and doing what you were told meant things would go well for you.

    However, being titled the good girl, you were sure of one thing; that was a lie.

    Summary

    It couldn’t be more cliche- you bumped into him while running to class because you were late. Of course it would start like that.

    Summary

    An old decorated tome about monsters wasn’t the most exciting thing one could find amongst your grandmother’s things but it did catch your attention. Fascinating depictions of magical creatures aside, it seemed more or less worthless.

    However a warning label came attached, inscribed on the inside of the cover with a rather clear message: don’t leave it open in the dark.

    "are you the owner of this book?"

    Of course you did what anyone would in your situation.

    You screamed.

    Summary

    It hasn’t been an easy 15 years since since the barrier atop Mt. Ebott broke and monsters were reintroduced to the surface world. The uneasy acceptance of monsterkind was hard won by many sacrifices though over the years tensions have settled into a general, though in some cases begrudging, acceptance.

    You are a grad student at the local university, eagerly pursuing a degree in Geophysics and Planetary Sciences in hopes of returning to the National Park Service. One step closer to the future you’ve had planned out since you were 17.

    Plans change, though… and along the way, you might undergo a metamorphosis too.
    *Please do not assume this is just a student/teacher kink fic, because it is not :)

    Summary

    You're human enough you suppose, for a person with magic. You don't really bother about it under normal circumstances, so most people don't really wonder about it. Sometimes, it's so much a part of you you even forget it's there and just live your life normally.

    So when you end up using it on a complete stranger, and get pulled into more unusual circumstances than you're comfortable with, you figure perhaps that fate is tired of you ignoring it.

    Summary

    It's not normal to be able to handle a coach gun at age 7.

    It's not normal to have a tattoo on your tenth birthday.

    It's not normal to go to graves and dig up corpses, pour salt then burn them.

    IT'S NOT NORMAL TO CHASE AFTER INNOCENT PEOPLE.

    DAD.

    STAHP.

    ~

    (Y/n) is the one and only little girl of the town's mechanic, though he's not a mechanic. Actually, between father and child, it is (Y/n) who is practically pulling the mechanic career together while her father jumps from city to city to get rid of certain problems as their family's main business.

    Hunting.

    No, not the hunting of animals like bears and wolves; (Y/n) wished it was that simple to believe. Even though she may cry at the sight of a pelt hung or just decorating the floor.

    "I smell your spawn. So fresh, her soul.. I feel it. AHAHAHAHAHA."

    Oh my god...

    Well, time for a trip to her favorite aunt and favorite cousins.

    ~

    What happens if the monster from Underground finally escaped?

    Can (Y/n) stop them from killing those kind-hearted creatures?

    She doesn't know how she'll protect them, but she will do everything to see through that they will never be harmed.

    Summary

    Hope noted the surprised look on Toriel's face and the nervous guilty anxiety she could feel coming off of Sans. Toriel looked from her to Sans then back again. It was hard to decipher what exactly the goat woman was thinking. She had looked shocked before but that had slowly shifted to suspicion. She closed the door and turned to face them both folding her arms over her chest.

    "She does not know?" She asked like it was a mild question. But San's head ducked down further into his clothes. Unperturbed Toriel pushed on. "How much time has passed since you started bonding?" Her arms folded over her chest and she watched Sans like a hawk. Curious about that as well Hope stared at Sans. His emotions were bouncing off of her and making a giant knot form in her stomach. Sans shifted uncomfortably unable to look at either of them.

    Summary

    when the world went up in flames as monsters crawled out of the underground, humanity turned to its best chance at survival : hunters; an organization specializing with dusting the things that go bump in the dark. you're one of those hunters, tasked with a mission that went ass up faster than you could even blink, all because you were arrogant and impatient. now you're stuck with the consequences and you'll be damned if you go down without a fight.

    it's...better than it sounds. and it will pick up after the first chapter, which is a bit of a bumpy ride.

    Summary

    Monsters returning to the surface was just another reason to avoid leaving the apartment besides your sometimes crippling social anxiety. But even a recluse who often slept through normal breakfast hours and forgot to eat lunch ran out of milk and toilet paper.

    Summary

    Sex.
    In human culture, it is both vilified as well as romanticized. Young people are both discouraged and encouraged to have it, and especially in a college party atmosphere, the mixed signals can be stressful.
    Then the monsters came to the surface, and from the other universes. It was never fully explained why or how, but it happened, and they were quick to stick together. Within months, Undertail University was founded by Dr. W. D. Gaster, and it gained a reputation as a thriving college atmosphere that boasted high graduation and success rates. It also boasted a very different view of sex, one that monsters had been entertaining for centuries.
    Somehow, against all odds and despite what people said, you’d applied.
    Somehow, you’d been accepted.
    And somehow, for some unknown reason...you’d enrolled.

    Summary

    you jumped into the underground, made your way through the ruins, and then you met sans. he likes what he sees and decides he's gonna keep you around for his own amusement. He's a nasty lil skeleton who never fails to remind you that he owns your ass and you kinda like it, but you also really don't. Consent as well as whether you like him or not is kinda a blurred, greyish area. Nevertheless, shenanigans and angsty love feels ensue

     

    Basically this will be shamelessly smutty and kinda twisted with nihilistic ideologies, dark humor and a fucked up lack of morals because I like that shit.
