Summary
Reboot of my original fic I made back in 2019!
After going into the woods to do their assignment, Kris, Susie, and Noelle find themselves falling into the underground. Kris, with the newfound autonomy that comes when the thing usually controlling you is busy with some kid and their ghost friend, needs to navigate how the trio is going to get back home, and how they can free themself from the clutches of the man that speaks in hands. Ghosts walk the underground, and a time looping 11 year old needs to have the "you can't keep killing and resetting everything, even if you can undo it again, stop listening to the voice in your head" talk.

Summary
Years after monster and human society merge, a young monster returns to the Underground with the intention of finding a story to tell. She finds that story in a stack of well loved letters between one Cathode and Mailman.
NOTICE: The final arc of this story contains implied suicidal ideation and serious self-destructive behaviors. If you are not in a position to read this sort of thing, you can stop reading after Chapter 22 and skip from there straight to the epilogue!

Summary
A perverted love child between Undertale and Overlord consummated with boredom and edgy hormones.
Osoma, a game that you had developed alongside your fellow developers, is scheduled to shut down and have all of its servers wiped today. Saddened to see your friends leave and to have something you have worked hard on end you decide to use the last few minutes of your time making a set of devilishly handsome Undertale NPC characters. When you were done you accepted what you had made and decided to stay in till the timer hit zero. Unfortunately, even though you were done with the game the game itself did not seem done with you. Now trapped and surrounded by your new creations giving you all sorts of devious ideas you need to decide what to do. Do you go along with what they say and take over the new lands that popped up around the original land of Osoma itself, find a way to get back to your own reality, or allow the first high level monster to kill you?

It’s been three years since monsters have integrated into society. After a frightening experience, you start to run into the same skeleton everywhere you go, and your lonely life soon makes a one-eighty turn. In a world where magic is real and monsters are kind, can you find a way to be part of it? Can you let yourself fall in love again? Can you prove to the world that Take On Me by Aha is the greatest song ever written? Because it definitely, definitely is.
PART ONE: Apartment - Chapters 1-50
PART TWO: House - Chapters 51-98
PART THREE: Home - Chapters 99-[tbd]The Reader uses she/her pronouns and is named--not a self-insert, more like a story in second-person. I don't generally reply to comments cuz I like an accurate comment count (2021 update: haha fuck that you WILL hear my love and appreciation. that is a threat). Author uses they/she pronouns plz default to "they" unless u know me, or yknow u can just call me Mod. Thank you! :D

Summary
They are trapped in a never-ending play, acting out the same roles over and over in the vague hopes that somehow, someday it will end. But it doesn't. So they deviate from the script, attempt to fulfill the purpose that brought them to the mountain in the first place in a last attempt to break free from the resets.
It doesn't work.
(But beneath their feet, the stage has begun to crack. After all, suicide is a pretty memorable thing, and emotions may just be a little bit stronger than memories.
Especially to the person who finds their dead body.)- Language:

And perhaps a bright new future is ahead. You don't know what to expect. Meeting a new family of monsters certainly wasn't even close to what you imagined.

Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.

Summary
You were a special kind of human.
Different.
Not only in what you were literally made of but also because of what you had been through.
Your scars were deep.
Your soul breaking.
Toriel has been your lifeline but she has never been able to mend your wounds.
It has been years since that day- but you still continued to slowly burn.
You aren't sure if anyone can help you at this point.
You needed someone who understood you; who could help you become a better person, who could help you grow.- Language:

Past Frans, Chapter 12 Papyrus and Raven Bonding Time!

Tags
Summary
Papyrus returns from training late one evening, and decides to ask Sans if he wants anything.
Sans is not there.
Papyrus shrugged it off, knowing Sans was probably at Grillby's, eating that disgusting, greasy food again. He was probably safe, drinking ketchup, telling puns and stories...
But Papyrus had a grim feeling that was not the case.
