    Summary

    You had been raised to be a hero, to defend humanity against monsters if they should ever show, but when they do-there's no need for heroes and no need for you.

    Years later you get summoned by your old boss to help with a problem that threatens the peace between monster and human kind. Someone you knew is tearing apart the fabric of reality and bringing boss monsters from alternative worlds to yours. You need to team up with the monster mascot and his boss brother plus their softer, alternative versions to track down the new arrivals and...make nice. But is that all?

    Summary

    This is a blend of a couple of ideas I've had floating around in my head for a while and finally decided to commit to one fic. The Royal delegation is heading north to sort out refugee status and establish an embassy in Canada's capital now that the barrier has been destroyed, but things take a turn when their carefully plotted trip is derailed by an almost fatal bus crash.

    Just as he's calculating how to get the monsters out safely as the vehicle is free-falling off of a cliff, he notices you doing something out of the corner of his eye as the bus slows it's descent. Did you just save them all?

    Summary

    Based off my parent work, I was just experimenting with the idea of what happens if my crazy optimistic reader meets someone grumpy like underfell Sans instead of the vanilla. I initially had no intentions to continue this, but damnit, I suppose I will.

    Sans is a hardass, but our MC has him wrapped around her crazy little finger.

    By the way, she's a pretty hardcore mage.

    When monsters were freed from the underground there was a large backlash of magic that had been stored up for thousands of years, turning mages to monsters. These Changelings now live side by side with monster yet they are different.

    Summary

    The barrier is broken. Monsters are free. And a whole lot shit has gone down.

    Y/N and Red had dated for a year before he left her on the side of the road, literally. He saw his love as a weakness and so, he took care of it the only way he knew how. Abandonment.
    Meanwhile, Y/N was left to pick up the pieces of the mess that he had caused. She was trying to hate him but failed every time. She just had to accept the fact that it was over and move on. And so she did.

    Fast forward to 3 years later and Y/N is a senior in college, living with her best friend Jo, and giving life her full potential. Jo was telling her about a new boyfriend she took up over the summer break, whose name was Blue. She really wanted Y/N to come over for dinner to meet him to which Y/N happily agreed, excited for her friend.

    Until they pulled into a house Y/N knew all to well. And a skeleton she had been trying to forget.

    Summary

    Sans doesn't know why he was attacked, he's so scared- He can't believe what's happened to him, and yet- Why is Red so kind? And what is this warmth in his soul...? He's never felt it before...He wants...to be close to Red. But he shouldn't want that, right? He should be disgusted with Red for what he's done to him!! And yet...Sans is only disgusted by himself...for he...doesn't want to let Red go...
    Red has a job, a job that he quite enjoys. He gives people their darkest desires. Some breaking and entering that ends in sexy time? Sure. Some heavy BDSM? He's down. Some rape play? He's cool with that. He was commissioned for a cute, small skeleton- And damn, was he excited. They were adorable, so small in his arms... But...their sobs were a bit too loud...Their shaking too real... They would say the safe word, right? They would stop this, right? Why aren't they stopping this? Just say the word!
    "Peppercorn", Red says, his voice hoarse as he looks into the sobbing monster's eye-lights.
    "...that's...a spice, right?" They responded between choked noises.

    Summary

    You didn't know what eating those people could do to you. You didn't know how falling into the underground would change you. You can't bring yourself to regret it, either way.

     

    Or, I wanted to read a fic where; Sans and Reader were already in a relationship with none of that waffling back and forth nonsense, surface monsters exist and reader is one of them, Horrortale Sans and Papyrus healing, and Reader becoming a Wendigo via eating humans and exposure to magic. This sort of popped into existence.

    Summary

    ( Updates once a week whenever I can push one out )

    You ( the reader ) had shrunken to the size of 7 inches tall. This is the case for a handful of others. When the barrier shattered the pent up magic needed a few hosts and so the few which were the most mage out of everyone had been overloaded with magic. This was because it awakened the mage in you causing your magic to go wayward.

    Due to monsters being the cause of this and a few hand-picked monsters were picked to house the affected. It was thought that by putting them together the magic stuck in you would stabilize causing you to grow.

    You were housed with a skeleton. They chose to house you specifically with his brother both being boss monsters. Sans the skeleton was a scientist. You were constantly measured and smothered in affection... This is before well... It turned to love.

    Summary

    You woke up in an unfamiliar place with an unfamiliar skeleton saying he loves you.

    You don't remember how you got there - only that he wasn't letting you leave: it wasn't safe outside, after all! How could the Magnificent Sans let something happen to someone as precious as you?

    And if he had to break you to keep you...? Well... He was good at putting things back together!

    Summary

    Your stomach rumbled. Making you move ever so slightly. It was nearing your feeding time anyway. You ever so slightly lifted your head off of your battered arms to give an ice cold glare to the glass window that separated your room to the rest of the asylum. The glare you were currently giving the window was one of those glares that could render a full grown man helpless. You smirked once more at that thought. Though this time, your smirk was plainly visible to the people currently monitoring you from the safety of the other side of the glass window you were currently looking at. That's right. They were safe from you with being on the other side of the glass.
