Summary
You're a simple person. You move quietly through life, taking classes and going home to enjoy your time as you please. You live near Mt. Ebott, and after the barrier's shattering monsters have slowly started surfacing into society and daily life. Although unaffected at first, perhaps it was stupid to think you could get by without ever interacting with monsters. On a morning that feels all too regular, you hurry ahead to class and run into a group of monsters. You pay it little mind, but that quick encounter would end up planting the seeds of great change.

Summary
(Y/n) gets super concerned over the disappearance of her best friend, Ashlyn. Ashlyn had gone insane after she downloaded a shady game. (Y/n) is told by the game(?) to go to Ashlyn's apartment, revealing that Ashlyn has been sucked into the game. The sensible thing to do is look for outside intervention, but (Y/n) isn't known for her good decision-making skills.
The game "Beautiful Soul Redemption" is a dating sim where the hero romances many Skeletons. Sadly, (Y/n) is not the protagonist; she's the antagonist. That doesn't mean that she can't smooch skeletons if she wants to; it just means that every little thing will be TEN TIMES HARDER. But that won't stop (Y/n). Because if she stops, that means she dies in the real world too.
Yay, Ultimatums!
To escape, she has to redeem the souls already trapped in the game. The more souls she saves, the more her soul gets redeemed too. Her actions affect everyone, yet it feels like everything is out of her control. A conflicting feeling, isn't it?

Summary
Having been born and raised in Ebott city, you’ve developed a passion for ocean-related things. Graduating from Ebott College for marine biology you love being near the ocean and helping out.
However, you haven’t gotten a chance to be hired for bigger jobs as you’ve settled for working at Ebott Aquarium, the 3rd largest Aquarium in America. You love your job and having worked at the aquarium for 2 years now, 3 including the internship, you're very vocal about saving animals especially sea animals dealing with pollution.So what happens if a water-loving person meets the monsters living in Mt. Ebott for centuries and what’ll happen when she meets a fire monster who loves the passion she has in her words and actions?
And what happens when she meets a skeleton monster who also loves how she voices her opinions?
I have no clue if this will have two love interests but I'll try! If not then I'll update this!

Summary
Dr. Vendette is Southern Trebane Hospital's "Miracle Doctor." Her quick thinking, cool demeanor, and no-nonsense attitude make her the star attending doctor in both north and south Trebane. Her reputation professionally is glowing, but everyone who knows her personally has differing reviews. More people hate her than she knows. Regardless, her untimely death shocked the whole of Trebane, and no one can argue that the city has lost its miracle.
Upon her death, Dr. Vendette is not greeted by pearly gates or hellish fire but by a disembodied voice in a dark void. The voices argue over her fate, and she wakes to find herself facing a new challenge. The young doctor has become the antagonist in a dating sim synthesized from the multiverse of her favorite game, Undertale. She will have to survive being the villain many believe her to be. After all, that's what an antagonist is, right?This is a reader-insert! A better explanation will be in the author's note at the end of chapter 1, but I will say this is a writing experiment for some of the darker themes produced by my other story of a similar concept, "They Call me Antagonist, but I prefer Anti-hero."

Summary
Dr. Gaster is searching for souls through dreams, but he finds one whose sexuality brings out the kink in every creature of the underworld.
No one seems safe from this girl's perseverance to be able to take just about anything. And it's driving Gaster wild with curiosity... and desire.
*Warning: plot is adorned with a shameless amount of sex.
*Tags updated as new kinks, pairs, and experiments are explored.
*Chapter Titles updated with pairings for those who want to skip past the plot and read specific pairings. I aim to please. Leave me a comment if I succeed ;-) -

Summary
You cross paths with the inimitable and extraordinary Black whilst sorting out your (rather unfortunate) affairs at the monster embassy. What happens next can only be described as a meet cute gone incredibly right, then crazily, awfully wrong when you find that his younger but taller (and equally skeletal) brother Mutt thinks of you as more than a friend.

Summary
Shattered Rewrite (different name)
You, dear reader, are the embodiment of death and chaos. You are the Mother of Monsters. For centuries, you have both protected monster kind from danger, and have created many legendary weapons and monsters alike. From dragons, to Typhon himself.
You are a monster, a demon and a goddess but you appear more like a human.
You may have created some monsters, but your children are legendary creatures, not those who lived Underground.
You have many names, from Death, Chaos and many others.
You decide you want the best for your daughter, Hel. You want her to have a normal childhood.
Well, you still have to watch the balance but as long as you can access your Inner Sanctum, all will be well. -

Summary
What if the Monsters weren't forgotten when they were sealed. What would happen if someone decided they wanted to help the Monsters in any way they were able to.
What if that someone was a Mage?
One day, a few years after the 6th Soul was taken, a voice started to sound throughout the Underground. A voice that sung a song for them, going for hours until going silent. The voice came back the next day, and the next and next after that one.
Soon all the monsters started to look forward to hearing the voice singing to them, it gave them HoPe, It told them that they weren't alone, nor were they forgotten by the Above World. And it told them that they had Human friends to look forward to when they are Free.
But the voice has to go on the Run, because there are those who do not want the Monsters free.
What will happen when their time runs out and they get chased into The Underground?
Will the Monsters still want her Soul to escape the Underground after so long, or will they try to find another way?

Summary
Going on a camping trip with your family wasn’t your all time favorite thing to do on the weekend, but it didn’t mean you didn’t try to enjoy it. You could understand where they were coming from, you did need to spend more time with them, your dear sibling tries to help you as well. Apparently they thought going near a mountain that is pretty much labeled “Cursed” and “Dangerous” was a good idea.
MT. EBOTT, the legendary mountain that is said to eat up every human and being that dares to walk on it.
You wonder what that all is about, your mom used to tell you it was all just some stories to make children of the village afraid, to make sure they wouldn’t go get lost around the mountain all alone. You kind of believed her, but you also believed in the monster history books that you read online from that one weird site… for whatever reason. So now you have to check some things out for yourself.
