    Summary

    (Y/N) was a normal human living in a normal world, until they weren’t... On April 4th 20XX, monsters emerged from the bigass mountain named Mt. Ebott with a child no older than 10 leading them like it wasn’t the weirdest thing. (Y/N) didn’t care for monsters, they didn’t hate them per-say, but they weren’t too fond of them either.

    Soon enough, with help from the government and the president, monsters were able to get comfortably situated into society, though of course, people were still specist jerkwads from time to time.

    Diagnosed with ADHD and DID from a young age and countless, sleepless nights due to insomnia; (Y/N) was what you could call, a trainwreck. Unfortunately, (Y/N)’s SOUL main trait was dishonesty, so it was also always a struggle to get people to believe your side of the story, even if it was obviously true.

    When a certain goopy skeleton monster stuck between the lines of time and space asks you to help save him in exchange for a chance to be normal, how could you say no?

     

    Well… only time can tell. ⌚

    Summary

    “So what are you doing here?” Sans says to you, with a look of genuine interest.

    “Like, here at this party? Or here at this college?” You say raising an eyebrow playfully.

    “Hm, both.” Sans says.

    “Well, honestly? I only agreed to go to college to appease my parents. I just picked the first thing that came to mind to major in honestly. And I'm at this college in particular because my friend, Adelya-” you say pointing in your friend's general direction, “-decided to go to college this year too.” Resting your hand back at your side. “Actually she is the reason I'm at this party too I guess.” You huff in amusement.

    “Appease your parents?” Sans was actually kinda surprised, he didn't think a soul as bright and powerful as yours would be forced into anything, but he doesn't know your situation enough to be the judge of that yet.

    Summary

    Ever wonder what might happen if someone from the fandom who knows way too much about Undertale were to suddenly end up in the world they've been obsessed with for years?
    Huh... me too. :3
    Just a heads up, this isn't a standard Isekai fanfic, there are fantastical elements that carry over from the transported character's home world for added flavor.

    Summary

    Once upon a time, there was a rift, a schism, that split man and beast in a great war. Mages and humans battled against the monsters, sealing them Underground with a magic spell, locking the brightest lights away in the darkest dark. With the lights gone, the world slowly fell to darkness; the greed of man, ever infinite, grew nonetheless.

    Shadows of great beings lurk around every corner, infesting every facet of life---but the people are clueless to the trouble that is coming. Even the universally selected Iudex, Judge, cannot stem the tide of the hidden war---one he knows not of but must fight.

    Can he unbind the lights from their prison in time? Can they save the world? Or will the beacons of hope dwindle in front of the dark night?

    Summary

    It's a pretty mundane event: a skeleton happens upon an injured cat and after taking the poor thing in for medical help ends up adopting them.

    And then it happens again.

Well clearly after they recover from their injuries they're going to have to be re-introduced to each other! But in the mean time these two bumbling owners are going to find out just how unprepared they are for the furry new additions to their families.

    Summary

    He'd never thought things would turn out this way.

    They were happy. He was happy. All he was supposed to think about was when his little brother was going to come out. This wasn't... this wasn't part of the future he'd seen laid out for them.

    Something in him, something old and burning and still human, told him that the story wasn't written like this.

    Sans stared down at the babybones wrapped in the red scarf he and his creator treasured so dearly. Papyrus was still so weak...

    "it's going to be okay," He told him. "i promise."

    But would he himself be okay?

    ---

    In which Sans has jumbled memories of a life long gone and adores people with a ferocity that's frightening and might just be the end of him someday.

    War is raging, but not the one you might be thinking of. Monsters and humans set their differences aside to fight together against the beasts that rised from the deepest of the ocean. Jaegers are being put back together from the dumps in one last desperate attempt to turn the tides before it's too late.

    One salvaged jaeger is ready to be deployed. Few candidates are deemed good enough to be potential pilots, and even fewer are potentially compatible.

    To everyone's astonishment, the one with the final say on the matter is this strange newcomer, who's all but predictable. He claims to be a pilot. Only time would tell.
