    Summary

    After Sans had the genius idea to mess with a machine he had created, he didn't expect that it would have brought versions of himself and his two brothers (Papyrus and Wingdings Gaster) to their universe. Nor did he expect that an old friend of his would introduce him to none other than his soulmate, or that his very soulmate was also his brother's and alternate versions' also.

    Summary

    There's two new skeletons in the house.

    Unfortunately not much of a surprise there, the machine kept malfunctioning and kept bringing in alternate versions of Sans and Papyruses into their universe. They were up to SIXTEEN SKELETONS, now eighteen with the two's newest arrival.

    Except... there was something off about the new skeletons. 'Visor' and 'Chine'.

    Sweet mercy above, these two brothers seemed to hate each other. They kept swearing at each other, calling each other names- Chine actually almost stabbed Visor! On purpose! What a toxic relationship! Even more so than Black and Mutt!

    Or is it? Underneath their hateful facade, they do care for each other. In another very weird but unhealthy way... That's it, everyone was going to try and help these two, as well find out more about what happened to them in the past, why they were what they were and maybe find a little love along the way.


    You and your brother never asked to become the alternate universe Sans and Papyrus you both created. But by fuck was it difficult to keep things together like this, now the AU Sans and Papyruses were trying to get close. Stars above have mercy on their SOULs.

    Summary

    A re-boot/remake of a old Wattpad story of mine called, "Our Identities"
    The old story plot wasn't bad it was just cringe but I decided to remake the entire thing~
    ___________

    Welcome to Mirage Noir Lune High!

    A school where variety of students and teachers are chaotic and just having fun! This was a place where you can call home as well if you wanted as there are dorms! A school for the chaotic, talented, and...uh dumbasses as well? How the school came to be, the multiverse sometimes is a bitch so they all collided and so forth the school was created to keep in check of the characters, even if the school has to go through drastic measures to keep everyone safe and sound.

    This is your average Highschool AU that has troublesome relationships with the principal and the multiverse is slowly dying right?
    I mean what could possible go wrong in this action romcom... right?

    Summary

    (Y/n) lost her job, which sucks. If only she hadn't lost her second job, and apartment, as well! Now all she's got is a camper full of her crap on the back of her truck, and nowhere to go. At least she found this campground, even if it is in the middle of nowhere, and looks like no one has been around it for a while, and a skeleton with a head wound tries to make her into a meal... Rough start to making new friends, but his brother is sweet enough!
    And then there's the other skeletons who inhabit the other cabins, who all look vaguely similar... Their explanation of "cousins" only goes so far, but there are more concerning things to worry about, like how almost every skeleton is trying to get into her pants, their heats, and where her clothes, particularly her socks, keep disappearing to?!

    Summary

    “...do not be rash...the only reason I am telling you this is because I need you to pay your tab.”

    Sweat formed on Sans’ brow. “What are you getting at, Grillby?”

    Grillby silently turned to the register on the far right of the bar and punched some buttons. After a moment, a long piece of paper spit out of a metal slot. It rolled onto the wooden floor. Grillby snatched it up, miraculously not burning the paper, and handed it to Sans. The skeleton’s eyelights browsed the paper, then quickly extinguished. His hands trembled. “This...can’t be right, Grillbz,” he mumbled, voice shaky. The bartender took the paper and distingrated it.

    “...I will forgive your tab just like this paper...if you take in (Y/n).”

    ***

    (Y/n) gets taken into the care of six skeletons! The only thing is, she has skelephobia...

    Will her mysterious past and daunting fear get in her way of love?

    (I suck at summaries, guys. Just read the dang thing if you've read this far down lol)
