Summary
Hiiii guys 😗🥲 it's been so long ya'll oh my gosh 😭😭😭
"
Getting a job at an aquarium was not something Gustav ever thought he'd be getting into.
He went to college, he studied culinary, he was great. But, y'know. Shit happens. Plans fall through. And you take chances.
So! When he stepped foot into that private area, he assumed it was some rare fish- although, while technically yes they are rare fish. Eeeeeh, he doesn't think.... that really counts.
Mermen.
Jesus christ what fucking dream has refused to loosen its grip on him.

Summary
On the day of their 13th birthday everyone has a name appear somewhere on their body. A script different than their own, but still familiar and comforting nonetheless. It's said to be your soulmates handwriting and, when you make physical contact for the first time, it's to change to the color or their eyes. Or so the rumor goes. But everyone knows that's just an old wives tale since finding yours is so far and few between.
But then there's Fanchon. What the hell is she supposed to do with 12 soulmates?? At least her odds are better than most...

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Without History (maybe some things should stay forgotten) by Human_with_no_life
Fandoms: Undertale (Video Game)
08 Oct 2025
Tags
Summary
After the barrier breaks and monsters and humans live together on the surface there is still mysteries about the underground to be solved. Most of them will stay forgotten or buried forever.
Until an almost promise Sans made frisk makes him tell a long and complicated story. His story, well not exactly 'his' but as many questions as it answers it raises more. One thing if for sure it will change everyone involved.
-
Tags
Summary
Sans has seen it all. Every reset, every route, every ending. The world keeps turning back on itself, and he's the only one who remembers. While others laugh, dream, and fight like it's the first time, he carries the burden of knowing it isn't the first time.
With each familiar face and every repeated moment, he begins to wonder if only this time would be different. His hope keeps growing and shrinking every time. Maybe the human chooses kindness. Maybe his brother's smile will stay safe. Or maybe it's just another game he's destined to lose. Still, he keeps going, for his brother, for the chance that maybe, just maybe, this path leades somewhere else.

Dualtale AU: Two sides of truth by ED_Soul
Fandoms: Undertale (Video Game), Underverse (webcomic)
07 Oct 2025
Tags
Summary
Description:
This story is based on the distant and little-known Dualtale AU,where nothing is as simple as it seems. In this world, unlike the original Undertale, monsters were never trapped underground. But what was the price for peace between humans and monsters? And how is it connected to XGaster, when these events unfolded long before the X-Event?
(Features characters from Underverse and Undertale,adapted for this story.)Author's Note:
In the Dualtale AU,the famous rule "Kill or Be Killed" is replaced by another:
"Speak out, and you will be silenced."
This is a universe built on lies and dark secrets that everyone holds.Every character has their own agenda and their own rules—and it's better not to try and learn them.Series

Summary
Gaster was just finishing off his cake when a neighboring party set off the first firework of the night. The skeleton jolted at the boom that quaked the mountain beneath them. Gaster did his best to quiet his rattling as colors burst in the sky. Grillby sat close and wrapped his warm arms around his shoulders. The skeleton took a breath and melted into the embrace.
