Summary
Every place has its legends. Legends of monsters, ghouls, and anything that goes bump in the night. Almost everyone believes those legends as kids; when they grow up some tend to outgrow their beliefs. The legends surrounding Mt. Ebbott were just stories to tell kids so they wouldn’t wander too far. Until one day monsters came out from the mountain. Everyone was forced to believe in the legends then. Whether they were young or old.
The monsters were friendly despite their imprisonment. They just wanted their freedom and to coexist in harmony. Humanity was lucky in that regard. But the arrivals of the monsters made people begin to think. What other legends are real and will they be as friendly?

You had died. You were sure it. How you had died, you didn't know. But you knew deep down in your Soul that you had. Which is why you were so confused by the fact you had woken up in your old apartment. Not in your lovely farm house you had fixed up with your skeleton boys, just in a small and quiet apartment.
Was this your chance at a redo? How did you end up back here? You were going to get to the bottom of things while also helping Monsters get a better start at life on the surface then they had the first go around.

Summary
Falling.
You were falling.
…Or were you?
You were weightless; both falling and floating; suspended in midair, nothing below your feet, but also no air flying past your face or whipping your hair around to tell of gravity’s play of hand.
And it was dark.
Suddenly, in the middle of the far distance, a white light appeared. With each passing second, it was growing bigger, bigger, and bigger still.
You realized, belatedly, that the light was drawing you in, tugging at your very being, and something about it was… awakening something within you.
The light grew closer, and your hope stirred.
You hadn’t wanted to die. You didn’t want to die.
You looked up into the light, and you reached out with everything you had.
With one final tug, the light pulled you into its embrace.
And just as tightly, you held on.

Summary
Reader lives in a post-apocalyptic hellhole, but is transported to the skeletons universe.
Authors note: This is a rewrite of my first 'Living in a graveyard' fic, I hadn't been real happy with how it was turning out, and I felt it'd turn out funky if I tried to re-do each chapter, so I'm just making a whole other fic and discontinuing the other one.

Summary
Honestly, Cherry didn't think that playing Undertale and reading an unhealthy amount of fanfiction was what lead her in this position. She wasn't happy at all. Because who the FUCK?! Would wish this upon someone? Sans the Skeleton, was a goofy character in a game, that was it. Nothing more, other than the fact that he has One HP and can still kick ass. But that was in a game. In reality? It was much scarier and alarms were blaring in her head. So yes, Fuck whoever brought her here, she didn't care. She just wanted to take a short nap. That was all.
(Hello! Somewhat new to fanfiction, this was inspired by so many great fanfiction, and once I can figure out how to put in the creators and their creation in this, I will. Thanks for reading, and if you don't want to that's also fine, please don't hate, and any healthy criticism is fine. I need assistance anyhow. Please don't rush me, I have a life like all of you, and I get lazy or burnt out at times. Thank you.)

Summary
You spend most of your days at Ebott's aquarium. Not just because you particularly loved marine life, but to spend time with the ones you felt truly understood you.
Sure, they kill people every other week, but to be fair..
You'd probably do that too if you were kept within a glorified glass box.

Summary
there wasn't really anything notable about your life, and as much as you like to say it doesn't bother you... well, time from time, it kinda does. that is, until a skeleton walks—literally—into your life. and then another. and then one more. and then, just to be sure, a last one. and as much as you like their company, you start to wonder if there's more hidden you're not aware of when it comes to them.

Summary
no matter what form, no matter what world, and no matter how many times, you'll fall back into familiarity with him as he will you.
(or one shots i've written from ambitious ideas for multi-chaptered fics i've had, most if not all tooth-rotting fluff with a slice-of-life touch to it. almost. mayhaps. perhaps a little bit of hurt/comfort sprinkled in.)

Summary
Life sucks.
Between a shitty job, a shitty landlord, and shitty mental health, you're ready to fall into a coma to avoid your problems.
Killer makes everything a little more bearable though. Even if he has no clue what the fuck he's doing.
