    Summary

         Y/n was having a nice day walking down the sidewalk. She had just gotten off with work and had exited the office wearing her coat since it was a chilly fall.  “Hey Y/n!” Macy y/n’s coworker waved running to catch up to y/n. “Would you wanna go get chicken wonton tacos? I want to introduce you to my fiance Travis.” She said pointing to a boy near her. “ Oh hello” They stood there talking for a while. Suddenly a scream rang out a man in a dark coat rushed forward with a knife down the street. Heading straight for Macy. Y/n always the quick thinker pushed macy out of the way and ended up taking the knife to the gut. Y/n fell over. Blood started to pour from the wound. y/n gasped she could hear people screaming “someone call 911!”  However in the end y/n succumbed to her injuries on the spot. You died and that should be the end right? Well monsters come back and a new beginning starts hopefully new relationships start to bloom too as you get used to your new skeleton body and magic.
    I'm surprised this is so popular! For anyone new this is a voter fic. So you comment on the newest chapters to influence the story. Each chapter is short. I post daily usually.

    Summary

    Y/n loves helping people, so they started a homeless shelter/food pantry/job search center for minority/marginalized groups. Their business starts up quicker than expected, thanks to the monsters emerging - but things get a little more difficult to manage when twelve skeletons make their way into y/n’s heart… and continuously sneak an adult toy into/steal it from his room. Who keeps taking it? And, who keeps putting it back…?

    (I’m low-key tired of Xreaders where the reader uses feminine pronouns… not that there’s anything wrong with them! Anyway, here’s a story where the reader is gender neutral/masc leaning. Reader uses he/him and they/them. Might be slow to update…)

    Psst!! I made a Discord. Check it out!

    Summary

    When invertos, people turned into monsters by their own innate magic, come about, they're herded into a facility to await True Monsters to host them, so the they can better learn to understand their new magic. That was seven years ago, and now it's just me in the facility. I've got some visitors now, and I think they're monsters hosting me out. Will I finally get out of here or is it just a false hope?

    Summary

    Everyone in the multiverse had a soulmate, is just a recent thing that occurred and now even the Guardians could hear the calling of their destined, sometimes a soft and warm voice that guided them, others were melodic like a song or heated with passion.

    What Nightmare heard was an agonizing plea for help and a cry that would have haunt him forever if he hadn’t found his soulmate the moment he did.

    Summary

    I bring you the area where I will put everything that is short and mini-chapters.

    Different topics that I like but i don't have the time to create a long fic…
    I will try more different topics here and even i will try to make new ones.

    I will add a lot of names from other authors here since my mainly idea is to help other people find ideas and create their own stuff.

    This area is for one shots, I think people calls them like that?
    Unrelated stories that have only 1 chapter or 2 if i make a pov from Sans.

    And also i will add the first chapter of long stories here to make you feel the boom of a new story beginning.

    That way you'll never miss one of my new fics and you will learn from yourself if you like the story or not.

    I accept ideas and suggestion. (Inside my possibilities and own likes)

    Summary

    You’ve always been a lone wolf, a restless drifter, a Bohemian who refuses to settle down. It might have something to do with the fact that you’re not quite human - you look like one well enough, but outward appearances have never helped you completely fit in with regular society.

    Even if nobody discovers your lifelong secret, that you’re able to become a bobcat at will, they still reject you. They always reject you. Thus, since running away from home years ago, you’ve been mostly on your own, wandering free...

    Until one fateful evening you're taken in by a household of skeleton monsters, and your carefree existence is changed forever, becoming irrevocably tangled up in their complicated lives - for better or worse.

    Summary

    Four AU’s have come to a happy ending on the surface. It is a new beginning for everyone, but Berry is haunted by his past that still clings to him and threatens to pull him back into the darkness, unknown to his now growing skeleton family. The newest skeletons are from the last set that surfaced: Fellswap. They are not going to let Berry be taken. Howl and Daemon, the two newest skeletons, have to dig into a horrible truth and show the world Berry’s past, and with the help of their fellow skeletons, they hope to make a better future for him and all other monsters.

    This is adapted from a role play with GetMcDunkedOn and me (Diyami). I hope you enjoy it.

    Summary

    (Y/n) gets super concerned over the disappearance of her best friend, Ashlyn. Ashlyn had gone insane after she downloaded a really shady game. (Y/n) is told by the game(?) to go to Ashlyn's apartment, and it is revealed that Ashlyn has been sucked into the game. The sensible thing to do is look for outside intervention, but (Y/n) isn't really known for her good decision-making skills.

    The game "Beautiful Soul Redemption" is a dating sim where the hero romances many Skeletons. Sadly, (Y/n) is not the protagonist; she's the antagonist. That doesn't mean that she can't smooch skeletons if she really wants to; it just means that every little thing will be TEN TIMES HARDER. But that won't stop (Y/n). Because if she stops, that means that she dies in the real world too.

    Yay, Ultimatums!

    For her to escape, she has to redeem the souls already trapped in the game. The more souls she saves, the more her soul gets redeemed too. Her actions affect everyone and everything, and yet it feels like everything is out of her control. A conflicting feeling, isn't it.
