    Summary

    When your creations turn into reality, things were never meant to go well. Both you and your brother turn into the characters that both of you created and dread to be in. An alternate universe full of death and war.

    -----

    You were tired from this. Hell, both of you were. You were placed in the front lines while your brother created dangerous explosives. All of this just to survive, to live for another day. All memories are forgotten of who you once were before this painful life.

    Who knew a sudden mishap of a machine could be a savior for the both of you?

    Dream was able to finally fall asleep when a cluster of fear from an Outertale au wakes him up with a jolt. It must be his brother doing, he has to stop him.

    Summary

    In a world where females are scarce and the Monsters are so used to death a young woman is forced to help save them. Although she is not the only one that had been summoned, the weight of her duty is still heavy. Hopefully with a bit of time she will succeed in her given tasks but until then she needs to watch out for those around her. As Monster's of all sorts come to ask to be her mate some don't take rejections so well. Thank goodness though that she has a few helping hands. Well they would be considered helpful if they left her alone for five gosh darn minutes.

    Summary

    Without stopping.

    She was running to this much talked about mountain.

    Which we never come back from.

    “And yet, Frisk… You came back…”

    But, what if it was all a ruse?
    What if your whole life had been based on secrets and lies? Would it be worth living?

    How can you save a whole population, when you can not even save yourself?

    •| ⊱✿⊰ |•

    EXA8, a creature created by humans in a laboratory, looks for Frisk and what seems to be in her memories, her seven siblings. They would have disappeared while going to Mount Ebott. After escaping, a chase lead her to this mountain. Inadvertently, she falls and wakes up in the Ruins, beginning her adventure.

    But, the illusion of freedom soon breaks because, she is not alone in her head… Her memories, her feelings, that different soul… Is her whole being really completely fabricated?

    Summary

    I was bored, and this is just Nezuko from Demon Slayer (KNY) mysteriously (for whatever reason) teleported into the Undertale Aus multiverse.

    Wattpad version has (more) images and updates more(?) often https://www.wattpad.com/story/295407214?utm_source=ios&utm_medium=link&utm_content=story_info&wp_page=story_details&wp_uname=Is_Am_CHILL&wp_originator=%2FPGItqzLCv68gDBNf12ZT9ARb2ev2f3sIr2CR6fW%2FCNjveXPJlBXjW03v13tQ8prDN8dIKR2DoFxuK9ybxIGaFokJmQU%2Fl%2B4Y09mAWQRPMIzg%2FSuM9R0mQJofMLI%2F9Kc

    And yes, this Ink knows multiple languages. This is a branch-off from my videos with Sans AUs reacting to Demon Slayer on my YT channel. (Cringe, I know) you don't need to watch them, but the story will make a bit of sense (?) all you need to know is that some of the Sanses have a slight idea about KNY

    All characters go to their respective owners, and I don't own any images.

    You can look up AmIsChill on YouTube for OLD cringe reaction vids

    Summary

    Halyn is your typical teenage Deltarune fan: she grew up up with Undertale, she quotes Spamton all the time, she watches far too many comic dubs... you get the point.
    One day, her friend tells her about special version of Deltarune accessible via Steam as a hidden beta. Hungry for potential early lore reveals, Halyn plays through it.
    Everything falls apart as she uncovers something she was never intended to see. Something dark. Something real. Something that she can't undo, no matter how hard she tries.

    "YOU ACCEPT EVERYTHING THAT WILL HAPPEN FROM NOW ON."

    No turning back now.

    Summary

    Becoming best friends with Sans was easy, but who knew having these feelings for him would be so hard?

    Monsters have been on the surface for a few years now and you’ve found yourself becoming friends with an unlikely lesbian monster couple. After being introduced to Alphys and Undyne’s friend group, you couldn't help but love them, but one monster stood out to you from the beginning.

    Is it better to stay quiet and hide your feelings forever, or to lose the only person who's ever understood and accepted you before?

    (will try to update as regularly as possible but can’t make promises lmaoo)

    Summary

    The First deemed it their job and so the Second continued it without hesitation. They called themselves River until the others knew them simply as the Riverperson.

    One word to define what they were.

    There had been other names - ones of all lengths and sounds from up above - until he or she became they - the Riverperson.

    They were just they.

    Summary

    (Y/n) gets super concerned over the disappearance of her best friend, Ashlyn. Ashlyn had gone insane after she downloaded a shady game. (Y/n) is told by the game(?) to go to Ashlyn's apartment, revealing that Ashlyn has been sucked into the game. The sensible thing to do is look for outside intervention, but (Y/n) isn't 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 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 she dies in the real world too.

    Yay, Ultimatums!

    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, yet it feels like everything is out of her control. A conflicting feeling, isn't it?
