Summary
When invertos, people turned into monsters by their own innate magic, come about, they're herded into a facility to await True Monsters to host them, so the they can better learn to understand their new magic. That was seven years ago, and now it's just me in the facility. I've got some visitors now, and I think they're monsters hosting me out. Will I finally get out of here or is it just a false hope?

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.

Not the best way to go about Life by Llama_Goddess

Summary
Monsters have been freed from the underground, and honestly, you don't really think they should have. You wouldn't consider yourself 'racist', you just fear for your own safety when murderers wander the streets and move in next door.
So spilling coffee all over a very large and intimidating skeleton monster was probably not your best move ever. But instead of gutting you, he offers to buy you another coffee. And, despite his... 'crude' language, he seems to be a nice guy. Maybe monsters aren't so bad after all?
But why do the monsters who used to pay you no mind now cast you pitying looks and avoid you all together?- Language:

Out of the Frying Pan and Into the Fire by Punklovergirl68

Summary
Your home life wasn’t the best, it was as simple as that—your parents were neglectful, your parents were verbally abusive, your parents…just didn’t care. Eventually, it just got to a point where you wanted out...
You wanted out, you wanted out, you wanted out, you wanted—
It felt like a miracle the day Nicole had gotten back in contact with you and asked if you wanted to move in with her and her…friends? Is that what they are to her, friends? It didn’t matter, you finally had a way out and, for that, you were grateful. How were you supposed to know that accepting her offer was going to be one of the worst decisions you've ever made in your life?
I’ve fallen quite in love with this anti-harem genre and wanted to give it a shot myself. This story is inspired by quite a good chunk of other anti-harem stories, but the main one that really made me want to write this was “There’s Still Magic” by RosesCry.

Summary
With the ascension of monsters, there hasn't been a boring day since. Living in a town close to the mountain range had its perks, and things certainly changed when the neighbourhood I lived in starts getting new residents.
The only problem now is finding a better job.
Luckily, a skeleton appears and tells me about a restaurant I can work at. I accept.
And I soon run into a whole bunch of other skeletons that all seem to like me.
Romantically, and I'm afraid of what will happen.-

Summary
Hidden deep in the snowy forest of Mount Ebott lays a crumbling stone temple that humanity has long forgotten the purpose of. Yet, it still patiently waits for the day someone, anyone to acknowledge its existence.
Everyone from the village of Frostmire has always been told to never approach that building. ‘It could easily collapse!’ They would say. It never did. No matter how many centuries passed it stood firm. Still no one dared to step through those doors.
Until one day I decided to take a calculated risk. Though the second I walked into that temple, and placed a small offering below that statue of an unknown deity I realized that I had gravely miscalculated.

What should I do if I moved into a murderous game with skeletons? by huilanchik

Summary
What if you also got into an otome game that you recently passed? So you don't know either. God, you're not even the protagonist, but just a background character who flashed through the story a couple of times!
"... Although, it's even better..." - you thought. After all, it's better for you to watch everything than to participate in a love drama.
However, things don't always go the way you want them to. And now love interests are sticking to you
"Leave me alone! Go to the protagonist!"
"Baby, we only need you."
What's wrong with this game?-

Summary
Xena Stone is a therapist who monsters go to because she seems well trusted.
What she didn't really expect was a 8 foot tall edgy skeleton to come up and coax her into learning to love and trust again.
This is a shitty fucking summary my dudes. xD But I'm sticking with it!
~~~~~~~~~~~~~~~
YO YO! So I don't have a strict schedule for this, cause I write it whenever I get an idea or the chance, but I'm hoping for daily or every other day updates. <3
Also, Xena Stone is just the named reader, because that's just easier for me to write. Feel free to change any descriptions or her name to fit your needs better. <3
This story is not finished, but it is being rewritten and reworked, and will be posted under the same name. This will remain here, as a memory for myself.

Your life is normal, beyond the fact that you have to hide that you are a hybrid monster. But beyond that, hiding was easy! You found a groove...
That is, until you meet a very charismatic skeleton and his brother...
Suddenly, hiding is much harder now.
Especially when one is incredibly suspicious of you and the other doesn't know how to knock.

Summary
When the rain came pouring down and he turned his back on a second chance at living, Sans knew he was done for.
This was it.
He knew he would turn to dust right in front of the convent he had been eyeing since he was left without a home or anything else to his name.
Then came a nun, reaching a hand out and offering him the mercy he longed for since the moment he stepped away from an easy life.
Now, Sans is determined to make the nun who gave him another chance at life feel as good as she makes him feel.
He wants a life alongside her.
The problem is convincing her out of her reluctance that he's worth the risk of leaving a life of faith behind.
