    Summary

    Demon AU

    Blue's a high up exorcist who's lost his passion for the job since he's been transferred to an office. A recent murder, however, sparks his zeal for 'Demon Hunting' once again when he's assigned to investigate it.

    What should be an easy open-and-shut case turns into complex labyrinth of questions as the small village's dark connections come to light - and it doesn't stop there.

    Well. At least there's the cute waiter at Grillby's to look forward to.

    Summary

    The world was broken- split, divided, and in disarray. Everything was on it's head- the things people thought they once knew were gone, wrong and changed.

    Yet their lives are far from ending, their stories not yet closed.

    The Void isn't darkness, but the Void isn't light. The Void will never truly be understood or tamed, by anyone, you see...

    The Void knows who it controls.

    The Void knows what it deserves.

    The Void knows when the times will change.

    The Void knows where it will happen.

    Yes, the Void knows why the world revolves the way it does.

    And it knows that it is ever-spinning.

    ***

    "Darkness isn't forever, though it may seem so.

    Whenever shadows engulf your world, I will be your candle.

    Don't forget, in your time of need, I am with you in the dark."

    Summary

    Sure, falling down was never your intention but while you're here why not have a good time? It's not like it'll last forever, your last step being the King of Monsters himself. With unstable determination you might aswell reschedule your fight and enjoy some time off from the surface. Just remember not to get too comfortable.

    With danger up ahead, one often confuses the danger nearby for happiness. And if lethargy takes a hold of you, you won't ever find a way back.

    Isn't that what you wanted...?

    Summary

    You're a terrible person.
    Which was pretty self-explanatory in it of itself, but nonetheless.
    Your descent into human tragedy had been anything but an overnight change, but, you know. Things happened, and the culmination of all your questionable life choices had led you to become the person you were now; a sarcastic, twenty-something-year-old nihilist with bleak prospects boarding on the line of alcoholism.

    So when you wake up after a night at a bar in a jacket that doesn't belong to you and a throbbing, all-consuming hangover, you're not exactly surprised. But when a certain red-eyed skeleton with a wolfish grin and anger management issues decides to insert himself into your trainwreck of a life, well. You aren't having it.

    Unfortunately, he's not taking no for an answer.

    Summary

    Asra was descended from a group of monster hunters. They had their origins in the war that time forgot, when the human-aligned mages locked away the monsters underground...or at least the ones they were able to catch in time. Those who remained went on to earn a place in various local legends, scattering all over the world for their own safety, and largely fading to the realm of myth. Bigfoot, Mothman, and the Jersey Devil among many others, known and unknown. It had earned the family a none too good reputation.

    When her mother sent her to investigate the Mt. Ebott disappearances, she wasn't expecting to learn that the old stories that ruined her life growing up were true. Now she had a choice to make....

    Summary

    Animals elected you their human overlord. Monsters want to munch on your tasty kindness soul. Then a hungry naga shows up at your doorstep asking for tomatoes.

    Summary

    Occasionally as the team works towards their ultimate goal of freeing monsters from the Underground for good, they need time to relax. And sometimes, Mettaton, the Underground's biggest (and currently only) star needs a break from his job. When both of these issues crash into each other, late-night crack-filled goodness is the result.

    This is technically still set in my normal universe, but not in any time near where I currently am writing and not for a long time to come. I still wanted to write these and I hope they are at least moderately funny.
