    Summary

    All you had wanted to do was explore the empty Undergrounds a few months after monsters emerged. And where had that gotten you? Kidnapped and locked in some psycho skeleton's basement.

    Luckily for you, you're "rescued" by other skeletons. Who all more or less look the same. Except you still can't go home, because you know about too much of something you're not suppose to know anything about.

    So now you're stuck in the Undergrounds with a creepy murderous looking Axe, a perverted Red who can't keep his hands to himself, a loud and obnoxious brat named Blackberry, a dog like Pup that won't control his instincts, and a carefree Sans.

    At least Blueberry is normal.... r-right?

    Summary

    As soon as Sans had fired the bullet, he felt the world slow down, his vision taking in every detail in that frozen moment as he felt the slow droop of his cigar begin to fall and the heavy smoke taste stick like glue in his mouth.

    The drawn out distant clink of bullet cases tinkling on the floor echoed around him, the muzzle flashes stuck mid-fire, the beads of sweat on his men’s faces shining with a sickly yellow glow as bullets hung in the air moving imperceptibly slow. Cards, poker chips and money were thrown up in the air as the trails of wood chips and dust flung everything aside. Tables were fixed in place as people cowered behind them as they flipped them up in a panic, fear and screams stopped in the still shot of time.

    Except one person.

    Her.

    A devil in a red dress.

    Summary

    Asra was raised by 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. This earned her family none too good a reputation in historical circles, as they continued to insist on their version of events.

    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

    If there was one thing you HATED in this world, it was dancing. A complete an utter waste of time which ended in bitterness and depression. Why had you even bothered to try such a thing? And it's not like you needed it anyway, you didn't feel an itch in your muscles nor the tapping of your feet to the radio that plays dimly from another apartment. You just want to get through university and get out from...whatever this was.

    Of course an entire mountain decides to explode with dancing monsters of all shapes and sizes. Dammit.

     

    =================

    Stars, Sans really couldn't get any lazier than he already was. With monsters pirouetting left and right of him, jamming it down the streets and waltzing all over his daily life, he really couldn't stand the sound of moving feet. All he wants is peace and quiet, to lose himself in the grey monotony of ketchup, sleep and tv. Even University is a huge chore and he barely scrapes the attendance on his courses.

    And somehow, even in all his seclusion, he ends up meeting you.

    Where you both ask yourselves the same question every day.

    Summary

    Constantly, the same thing over and over, no matter what Frisk did, no matter what Chara tried. They were becoming numb to it. And so, they laid there, starting up at the opening they fell through, refusing to even start. That's when they heard you call out to them.
