    Summary

    Undertale Sans (Comic) hasn't had the best of life in anything. His universe is caught in an endless cycle of resets and death, and he has the worst luck with dates. His brother, Papyrus (Rus), gets more dates than he does, and he doesn't even remember them! One day, two oddly familiar skeletons are found in Toriel's puzzles. They look like the Tale brothers, but speak of other universes, stuck under the same curse of resets.

    The smaller Sans, Blue, catches Comic's eye immediately. But not all is as they seem behind those big, beautiful, innocent eyes...

    For Solo! <3

    Summary

    It’s been forty years since monsters came to the Surface, and five years since you moved across the country to live on the west coast. You were born with magic sensitivity, like thousands of other humans since the destruction of the Barrier, and the closer you move to the source of magic the happier you feel. It helps that one of the best law schools in the country isn’t far away. To make ends meet while in school, you work for your cousin in his tattoo parlor that employs humans and a very handy monster.

    An unknown, and dashing, skeleton monster walks through the doors one winter with unknown intentions. Now, he’s asked you on a date, you’ve met Frisk (the Frisk! Crazy!), and you’re the happiest you’ve been in years. Who would have thought this holiday season would give you such a gift?

    But be careful, because even on Christmas, things can be too good to be true…

    Summary

    You had to hand it to the plant. Although you didn’t trust him, you definitely didn’t trust the ragged goat lady even more and once you mentioned him as he suggested, she left you in her house alone, when you promised to go to sleep in the kid-sized bed you barely fit into. Once you were sure she left, you took a chance on the directions the flower, Flowey, gave you. And now you were here, trying to make sure the dead stayed dead because hell had apparently frozen over.
