Summary
“I CAN’T OPEN THIS BLASTED BOX!! IS THIS SOME KIND OF JAPE?! WHY WOULD HUMANS SELL SOMETHING LIKE THIS?!”
The sound of a trombone plays.
“SANS!! WHAT DID I TELL YOU ABOUT PLAGUING MY LIFE WITH INCIDENTAL MUSIC?!”
“that you love it and want me to do it more?”
“SANS, I WILL DUST YOU.”
“pretty sure that’s workplace harassment.”
“IT IS NOT!”
“is too.”
Envy closes her eyes and tunes them out again as their argument devolves into yelling. She just has to get through today, tomorrow, and the rest of her life. That’s not so bad.(AKA, a less-than-pleasant dojo owner who has too many problems of her own to deal with forgets to take down a "help wanted" sign.)
Please read the before-story author's note of the first chapter!

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.

Summary

After moving, they find themselves camping until something happens and now the two will travel together in order to escape the Underground filled with creatures that were only believable to see in fantasy books.Notes:
the Undertale tags are there because I want to make an Omori x Undertale fanfic, but there won't be anything related to Undertale during the first two chapters except for some references to Mt. Ebott and its legend, but around Chapter 3 or 4 onward, the Journey through the underground will begin!
So stay PATIENT!Series

Summary
The human was not gonna back down nor fight, and Sans, if possible, wanted to avoid a violent escalation of the situation as well. Because, despite the souls’ best efforts, his body had not yet recovered from his escape. Every single one of his bones ached, and he was almost certain that the cracks that already covered a majority of his skull had expanded.
However, the stalemate didn’t last long because, as it seemed, the human had an ace up their sleeve. The outline of a black soul manifested on their chest and, soon after, a bright red button with ‘RESET’ written on it appeared in front of them. Sans barely had the time to notice Killer’s eyes go wide and wonder why that was before the human pressed it.
Sans stumbled onto a snowy path with no grace, alone and lost in an unfamiliar frosted forest. Snowflakes slammed harshly against his bones. They looked so delicate and yet he could swear they left a thousand tiny cuts on him. It was torturous… and yet familiar.
That was the power of a human. No. That was the power of an anomaly.

Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series

Summary
Frisk couldn't recall exactly how many times he had been in this same position.
He had lost count on how many times he tried and failed. Lost count on how many times he had died. How many times he had RESET.
It didn't matter what he did, he always ended up failing. No matter what choice he made, he failed.
