    Summary

    You and your sick little sister are stuck in a bad position.
    Without a home or money, you have no choice to stay at Grimm's Hospital for Youth's Cancer.
    For a cost.
    When you can't take it anymore, you grab your sister and run to the east side of your city.
    Where the monsters live.
    You wish you'd thought to learn more about the monsters when they came to the surface four years ago.
    Now, you have to survive a world full of chairs with names and super-strong fish warriors.
    Oh, the horror.

    Summary

    Even without the collar proclaiming it, it was clear you were his. The many bruises and marks he left on his body left no doubt, not to mention the invisible bruises on your soul from where he plays with your mind. But then there are the other bruises, the ones he could never have seen coming, the ones on his own soul.

    Because mind games? Are something that two can play.

    Summary

    You never really know when you'll run into someone who makes your life really worth living...

    A second chance can be a rarity, but you may as well make the most of it.
    Love can take the form of many things, changing your development as a person in different ways. He may not have skin or organs, but you've managed to steal his heart.

    (Inspired by Overgrowth as well as some other fictions depicting alternate universes and endings)

    Summary

    "You will find the fallen children, and bring them home to me."

    ~

    Lost deep within the realm of Monsters, Integrity has forgotten everything: their past, their power, their name.
    They only know that they have one goal, but cannot remember how or why.

    They know that true names hold power, but are they truly powerless if they cannot remember their own?

    The memories once hidden in a cloak of darkness are slowly but surely revealed.
    Integrity finds their identity directly opposes the very virtues and morals that their Soul upholds.
    After discovering one's true self, they have to deal with the consequences.

    ~

    Will you kill for your own freedom, or die to save them all?

    Despite seeming so impossible, perhaps there is a third option.

    Summary

    It's been over a year since the Underground opened up and the monsters living under the earth swarmed to the surface in their thousands. The human and monster governments are taking their sweet time coming to any kind of agreement regarding monster rights and citizenship, but for the most part, in the less politically-active parts of the nation, life continues as it always has. In your sleepy little town, there are bills to be paid, tables to be waited, and few to no adventures to be found. So when two skeleton monsters move into the empty house near the café where you work, you welcome the changes they bring with them.

    You knew if you let them into your life they'd make interesting friends. What you didn't expect was that getting to know these remarkable strangers would be like coming home.

    Summary

    You've been through shit you shouldn't have to anymore, so, in order to protect yourself, you've been separating yourself from the outside world little by little. Daydreaming, music, novels, fan fiction, video games keep you the most distracted. The last game you played was Undertale, you read a bit about its AUs. You end up inside one of those AUs, but can't remember how you got there. How does it affect you to be there? You're not the innocent and cute teenager that makes Sans or Papyrus fall in love with you, like most fan fiction stories depict. You're a woman, around her 30's, just divorced from an asshole that used you as a shared sex toy for about 10 years.

    Summary

    Mobstuck AU

    When Sans offered you a job, you thought he was crazy. You were a waitress in a diner, why on earth did he think giving you an important job was a smart idea? Not that you could know but the important parts came after hours when the real business could take place. Him and Papyrus want to protect you, the only way to do that is to keep you shielded from what goes on.

    Unfortunately, that seems inevitable.

    Danger seems to want to follow you.

    Summary

    Three years. That's how long it's been since monsters have joined humans on the surface world. It's been a pretty big adjustment for everyone. With how most people took this though, it really did show that history repeats itself, even if this was definitely something entirely new to the world. My encounter with monsters has been next to none. Heh, that's about to change. My life was about to become a ton more interesting; a skele-ton.

    Summary

    Monsters and humans are... sort of getting along. Although they technically have equal rights, things aren't exactly easy-peasy-lemon-squeazy. An anti-monster gang has sprung up and wreaked havoc around the country. Naturally, a race of monsters who live off of violence aren't exactly the type to shy away from a fight. Rumors are spreading about the possibility of another Monster vs. Human War, and things aren't looking good.

    Nevertheless, both sides are pouring into your clinic after their nightly brawls, but how does one heal a monster? It's a good thing you have a bit of magic up your sleeve, but careful! Mages aren't supposed to exist anymore.

    Let's not forget that there's a certain edgy skeleton who fell for you since the day you patched him up after hours. You had brains, looks, and one of the most stubborn SOULS he's ever seen. He thought you were an actual angel, and if anyone tried to clip your wings, well, he was gonna have a great time showing them what happens when they mess with his girl.

    It's only a matter of time before someone steps out of line. After all, in this world, it's kill or be killed. But one question remains: which side has the real monsters?

    Summary

    A human girl thinks she's ending her life when she throws herself down a crack on Mt Ebott but is found and healed by the skeleton brothers. It soon becomes clear that she might be a much anticipated priestess who has the power to summon the beast god that can free monsters from the underground. She must travel through timelines and alternate universes to find her guardians, skeleton monsters with strong souls who will aid her in her quest to break the barrier and maker her dreams come true.

    Fushigi Yuugi/Undertale hybrid fic written purely for readers wish fulfillment and reverse harem fantasies! ;) Gonna try to keep it pg 13 but I might do nsfw ficlets and short stories based on what if scenarios.

    Summary

    Set after the events of Hell is a Place on the Surface.

    In the aftermath of the fiasco at the penthouse of one Victor Masters, the Surface is in greater turmoil then before. Monsters—collared or not—are treated with suspicion and many are being sold to government funded ‘shelters’ where the monsters are never heard from again…

    You have been busy handling the fallout in your own way. The matters of the surface hardly make it all the way to Snowdin, where you, Sans, Frisk, Papyrus and the mysterious Lyris currently reside. You have your hands full managing this house so things don’t collapse in on themselves.

    Soon, something will surface that will force you to face the horrors of the Surface once again, but all you want is to find peace.
