Summary

Summary
There's no DessElle fluff on AO3? It's all angst or smut? Guess who, idiots.
After a theoretical good ending (using what we know before chapter 5 release) where everyone is happy and Dess is in fact the knight (or was), she has to readjust to life after being stuck in time prison in the shelter for years. She was kept in perfect stasis, making her physically still 16 (or whenever it was she disappeared) and much the same as when she left. Plus the added PTSD of being stuck as the shelter. Noelle, however, has started to develop feelings for her.
The first chapter consists of the setup and confession, the second chapter will be a lot of fluff and just a little bit of smut. Probably.

Summary
“Shut. Up.” She’s glowering, growling, and it’s then that it occurs to Kris that the sheer frustration with which her knuckles clench the stupid 'linear equations worksheet' can’t possibly be from the backfire of a mere prank. “I’ll- gimme your phone or somethin’, or- dunno, the Librarby computer, or-”
Her yellowed eyes start to redden, and it’s only then that Kris realizes they’re watering. Not crying, no—but something close to it. Her voice is breaking and her face is scrunched up with rage.
Oh.
She wasn’t messing around.
In which Susie struggles with math, and Kris struggles with realizing her struggle is genuine.

Summary
This will be a series of Kris x Reader oneshots! In each chapter, reader will be conveyed as some sort of dog or wolf or fox (ik that they got their differences, but I'm clumping them together this one time) monster. The reader is also AFAB and has they/them pronouns. I miiiigghtt open requests for oneshots eventually, but not at the moment. The first chapter is just pure fluff (most prob will be) so I hope you enjoy!!!

Summary
Noelle Holliday wakes up with a voice in her head. Under normal circumstances, this would be cause for concern. But these are hardly normal circumstances, and the things whispered by the stranger lead Noelle into the tangled web of mysteries and secrets buried within Hometown.
Oh, and it says it can get her a date, so at least there's that?

Expect spoilers for Deltarune and Undertale, obviously.

Summary
An Angel scorned, with tears of fire;
The bitter path; of thorny mire;
All countdown to the Earth's expire.A soul of Justice; borne true and bright.
One of Compassion; with monstrous might.
Usurped from deepest, darkest black;
A Prince of hollows, bearing lack.Two Hearts;
Two Ends.
They play their parts,
In rage-wrought bends.
From burning vengeance, a twisted boon;
Faux transcendance, of DELTARUNE. -

Summary
He hooked a lazy finger around one. “What, these things? Well… we're all a puppet to our purpose, aren’t we?” As if in response, the threads went taut around his neck, forcing his chin unnaturally upwards. “Bet your strings are even tighter.”
Tenna swallowed hard. A million angry questions rattled his casing but his tongue stilled at the sight of the strings. They led Spamton back into the living room. Tenna slowly followed.
“Hey! That's enough!” Tenna finally found his voice, shakily forcing it out of his speakers. “You owe me some answers.”
“Sorry, Ant. I'm just your little mailman tonight. I've got a message.”
“A message?”
“You're going to be visited by three Ghosts of Christmas.”
It sounded ridiculous, such a whimsical phrase leaving Spamton’s mouth in his gruff tone. But Spamton’s smirk vanished as he spoke.
“Are we really doing this?” Tenna whined.

Summary
Welcome to Crossover's Peak Academy! A school used for students from different worlds- Wait, what do you mean we have new students enrolling today?!
Basically, this is a What IF scenario where the UMT cast was brought into an abandoned school building instead of the island, thus leading into different scenarios unlike the original.
This fanfiction is inspired by Danganronpa: Ultimate Meme Team! and Game of Life & Death (Fandom Danganronpa), although it's fine that you don't check either of them. (It's more fun that way)

Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.
