Summary
"Did you know? Your hands are the agents of change. Every time I go to see movies, when a character in them, is in a middle of realising something about themselves, they look and their hands and say something like... 'What have I done?' or something like that. I wonder, what do you think, when you look, habitually I might add, at your hands like that?"
"I..."
"Don't bother! It's no fun when a character just reveals his motivations like that!... I'd rather guess."
~~~~
An Error-centric story about changing yourself I think. Oh and the Star Sanses don't exist in this one. Oh and Error's working with Dream now. Oh and Ink is morally flexible grey opportunist – otherwise a bitch (that I fucking love(I like my man morally grey/downright evil, aye?)) Kind of a mix between FGoD and other fics that are alike, but I add some stuff I like, and pretend like I know what I'm doing. Enjoy?
(Sitirro watched 'Therapist Plays Slay the Princess' and thought 'Wow this game is so cool, and the writing is so amazing, it lowkey inspires me to write my own story, that I'll may or may not abandon after the prologue. You know what? Fuck it let's do it!')

Summary
It was a horrible day.
Everything that could have went wrong, went wrong. Your life fell apart in your own hands, your grasp rendering too shaky to hold a thing together. You would do anything to have more control of your life...
A glistening golden flower sprouts from the ground by you. It bares a friendly smile and twinkly eyes. You turn your head it and narrow your eyes, could you be seeing things..?
It introduces itself as Flowey the Flower. Seeing your state, it offers a game of Humans V Monsters: If you lose, take a small blow. If you win, become stronger. It winks, a starry gleam of light escaping its eye.
Out of pure desperation, you accept. It's skilled—the flower. Its beat you many times now and whacked you with it's throned vine.
But eventually..you beat it. A rush of triumphant pride surges within your SOUL! You flash a smile, and stare down at the flower smugly.
It congratulates you, and sends a tiny white pellet your way. It collided with you, and somehow...
You became stronger.Seeing your glee at the prize, it offers an opportunity:
9/15, 9:00 AM. Stand outside your home. Six games.If you win..?
A power equivalent to seven human souls.

Summary
Riri had spent her whole life miserable.
At least, until she met her adopted dad, Jeno. He was a true light in her life. And so was his husband, Ender. It was a shame she didn't find them until she was 17.
Now, she's an adult, trying to figure out her role in the multiverse. That's right, apparently there's a multiverse. And both her adopted parents are varients of a skeleton called Sans. She honestly gave up trying to understand everything years ago.
From one chance meeting, she happens to run into Soul Master, a Sans with the ability to change souls into someone else's and cursed with an insatiable lust. She's hooked from the start!
Only problem is, he doesn't seem to really want anything to do with her.

Summary
“I think, by now, you don’t need me to tell you that I’m not human. So… yeah, some part of me can be in your dreams. Or, at least, when you dream of me, that version of me is aware of it. I still don’t get all the details myself.”
A lost soul seeks to reunite with their friends. They almost feel like they finally have a future again.

Summary
You've been in The Void for so long that you can't recall anything. Then you find a way out in the form of a skeleton that uses the damn thing as an express highway. Well, sort of. Only he can see you. Your memories are being weird too, since everything seems so familiar even though you can't recall anything.
Then the human falls, and everything goes downhill.OC-centric fic written from second person, it's not all angst but there's basically no comfort for everything that goes wrong (at least at the story's current point). Arc 2 is multiverse stuff
Arc 1: Rock Bottom, 1-11
Arc 2: Funhouse Mirrors, 12-? -

To steal a purple soul (And hold it gently in your hands) by Feniksiara

Summary
To hold admiration towards a man who never interacted with anyone was foolish. To want to get closer to him despite knowing what he's capable of was even more so. But was it truly so foolish if her devotion was eventually noticed? Perhaps the reclusive man held more in his heart than cold calculations, if only for one person. One woman, who managed to steal his soul and held it gently despite his crimes.
Or: Reader is determined to help in any way she can and manages to slowly slip through XGaster's walls and into his soul. Neither knows what to do and is too blind to notice the pining. XAlphys and Ink are amused, until they aren't.

Summary
Error wakes up in a game he never chose to play—Until The Last Breath, a brutal survival world hidden between life and death. The only players? People trapped in comas. The only way out? Win.
To survive, he must fight through deadly floors, forge uneasy alliances, and follow three unbreakable rules:
[ 1. GAME OVER means death, both in-game and in real life. ]
[ 2. Artifacts must be crafted from Fragments found throughout the world by a Player. ]
[ 3. Reach the final floor before the chronometer runs out… or fade away forever. ]
There are no second chances. No resets. Just the questions: can Error and his team beat the game before it beats them—and can love survive in a world designed to tear everything away?

Summary
A household full of skeletons are competing over the attentions of one love.
This isn't that house though.Unbeknownst to the group secretively wrestling with their chaotic love lives and universe-meddling machine, another house a few doors down has been gifted with its own skeleton posse clamoring for the attentions of their own little lady.
A little old lady by the name of Mabel.Is there a bitty or a monster you would like to have a bitty version to drop into the story? I might find a way.
Lots of plot to come, aiming to update monthly ideally, depends on work and life!
