Summary
A look into the time after the Barrier between worlds was broken, told in separate but connected vignettes.
Or:
The story of three humans, the monsters they knew, and how they worked toward a common goal without realizing it.
I fought all through the night, oh, oh, but I made it alive.
The sun's starting to rise, oh, oh, these are beautiful times.
This fight of my life is so hard, so hard, so hard...
But I'm gonna survive.
Oh, oh, these are beautiful times.Series

Summary
Waking up buried in snow, alone, and with no memories but basic common sense?
Check.
Seeing numbers, words, and broken code floating around every object and surface?
Also check.
Looking like a walking system crash—with one eye red, the other computer-blue, and a body flickering like corrupted a light?
Triple check.He doesn’t know who he is.
He doesn’t know what happened.
And most importantly...
He doesn’t know why everything feels like he shouldn't be alive.Everywhere he looks, the world speaks in code—and he can read it like instinct. Names, stats, system files, broken timelines. And yet, the more he tries to remember, the more he feels like a mistake.
Note from the Me:
This is my take on Fatal Error—a much more none canon, wandering version of him. He’s not fully canon-compliant inn terms of power and has a different origin and personality. It’s a reimagining: glitchy, lonely, and filled with questions, bad puns, power and some more bad puns. -

Summary
This is basically a rewrite of Anti-harem to yandere + obsessive harem.
I wanted to write the first chapter, since I didn't know how to write something like this during my first time.
I'll also be revising and rewriting the smut and other chapters to improve them.
I hope that you'll enjoy this.

Summary
Sans couldn't believe he just did that! Stupid, stupid, stupid! When the Dean was going to refuse to give him the job because he didn't have a human partner, he lied straight to the man's face and said he did! Now he was expected to bring them to a facility party to prove that they exist.
Where was Sans supposed to find a human to 'date' him in a week? It's not like a human willing to spend any amount of time with him was just gonna fall out of the sky. And if they did, they most likely would laugh in his face about pretending to be his partner.
"Hey, Sans. Did you get the job?"

Summary
Chara died, and wake up again as a ghost, the first thing they see is a monster trying to kill a human kid, so they make the most reasonable assumption they can think of: The human did something so evil even nice monsters want to kill them. (they're wrong) They will do something about it even if they can't interact with the world, other than talking to the human, they just need a good enough plan... they just have to be creative!
Frisk just fell in a hole and now there are people trying to kill them and also they're haunted... which sounds worse than it is, because they are haunted by this... small kid, who probably can just talk to them and nothing else, the one problem is that they keep telling them to go fight someone for some reason, and they are being very annoying about it...
...Anyway basically Chara is a small gremlin child that gives Frisk headache occasionally... sometimes... usually... they'll be freinds eventually. (didn't take that long, honestly)
(This used to be a one shot, you can read the first chapter that way if you want to, the story kind of change... a... more than a bit, so I changed the summary, the old one for the Oneshot is in the first Chapter Note below here)

Summary
You don't know what those skeletons were so upset about, you weren't doing anything wrong. Though, you suppose that never really mattered. They hated you no matter what you said or did. But... you never thought they'd kick you out over something like dating one of them, especially someone they never seemed to like either.
Well, it's probably best you two just leave. You're not wanted there anyway, right?Series

Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.

Summary
Everyone knows the story of Undertale. But what if something changed? Just like the tale for-told, King Asgore, King of monsters, declared war on all of humanity after both his human child and biological son died to the hands of the humans who lived in the village on the surface. But tragedy struck, and Asgore died in the war he created for himself.
The King’s ex wife, Queen Toriel, now finds herself trapped within a dire situation he had left for her. She managed to bring the war to an end peacefully like she wanted, but at the cost of her fellow monster’s freedom. The humans created the barrier, and trapped all monsters underground. Queen Toriel, her heart now broken into pieces and now remolded into something darker, set a rule where all humans that fall into the underground won’t be killed, but will instead be made into slaves.
But what happens when it’s a child that falls into her newly established hell? Will her heart be opened up once more? And will a silly little skeleton help her find the most precious thing she lost? You’ll just have to read to find out.
