TW: Suicide Idelation, Depression Implied child abuse/neglect so if theses thing trigger you dont read
This is an Undertale AU developed and written by me , so here's a brief summary of what happens in this AU after the players/frisk's 18th's genocide run, though this time in the judgement hall everything seemed a bit different like.. some things weren't there when they should've been. Following this during Chara's Confrontation as they were about to press Erase, Frisk pressed reset at the same time going back in time way back, something that shouldn't have happened in the first place that will now forever mess with the game files.

Summary
We're back with another year of Inkwhumptobertale!
And this year, we have another twist: another list! That's right: every day, I'll be facing the challenge of eight different unrelated prompts, and I'll have to do my best to cram them all into the story, somehow. Admittedly, there is a low chance of me actually doing that, but I am obligated to use at least three prompts each day, and I'll add more if possible. I'd like to do at least one day fitting all eight prompts into the story at some point in the month, though. So..prepare for chaos!
These characters are not mine!

Trials of Golden Katana by MiloszeKox3

Summary
December 16th, 10:30
Monsters and humans live peacefully on the surface, without any grudges. In the era of progress, monsters completely abandoned magic, as it was no match for new inventions.
This day was very special for one fox - Kanako. As this was her first... trial? That's right, this story will be different from the rest. Here, she will face opponents not in a fight, but in court. Kanako's a defense attorney, trying to find truth and deliver justice to the ones who are really guilty. On her way she will face serious enemies, but she's supported by her mother, Ceroba and "uncle", Starlo. Will she be able to solve the mystery around her father?
This fanfiction is inspired by Ace Attorney games, but don't worry. Cases are designed from scratch (exept for the first one, more details in notes). Also, huge thanks to the whole KanaClover Discord server for advice! (Some ideas for cases were taken from them).

Summary
Long ago, deep in the quiet woods of the Underground, Grillby sought only solitude. He never expected to find a fallen human woman-wounded, frightened, and far from home. Against his better judgment, he took her in. At first, it was duty that kept her hidden and safe from the Royal Guard. But when her laughter began to fill the spaces between his silences, protection became something deeper.
When word of her existence spread, Grillby made a dangerous choice: he marked her under his protection, binding her fate to his flame. Their bond grew-slowly, tenderly-but like the flowers she loved, her life bloomed briefly. And then it ended, leaving only memories and ash.
Centuries later, on the Surface, Grillby runs a quiet bar and tells himself he’s content. That is, until a new regular walks through the door - a woman with the same gentle voice, the same curious eyes. There’s something achingly familiar about her, like a dream half-remembered. His flame stirs, warmer than it’s been in ages.
But can love reignite across lifetimes? -

Summary
Ink is killed, one day, somewhere in the multiverse.
He returns a month later and life continues.
Two years later, Dream is mortally wounded in battle, leading to an imbalance between good and evil. Blue is in too deep, Nightmare is reaping the results of his actions, Error isn’t acting quite right. Morality stops being black and white as lines start to blur. A deeper force begins to seep into the constant battles, exposing the multiverse's rotting core and foreshadowing an era of darkness, the likes of which haven't been experienced since the X-event.
Ink was killed, once, planting the seeds of something greater than he could have ever imagined, and bringing him closer to the one person he never thought he'd truly understand.

Summary
Getting up in the mornings is never an easy thing. Getting up in the morning to discover that you have taken over the body of Error isn't any easier, either. Now you are trapped in the Anti-Void with a constant stream of voices, confused, excited, and just a little hungry.

Just some short warm-ups that I have written. I might flesh them out into a proper story one day.Sorry guys for the massive time between updates, I am very bad at that apparently.

After the original TOTM was cancelled due to budget cuts, Caddicarus has been tasked with bringing the show back for more money-I mean entertainment.
With 12 veterans versus 12 newcomers living in a new state of the art resort only the richest people in the whole multiverse can afford, this show will surely be better than it's original version by a long mile!Series

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.
