Summary
You didn’t really care, they were just distracting you now, distracting you from the sea of stars above you, your hand lifting of its own volition — the stars shine, just out of your reach.
One foot lifts, the heel falling away, clattering noisily to the floor, your toes pressing daintily to the terrace’s railings, bracing as you heave yourself up to stand, skirts billowing and flowing and flying about your body as your remaining shoe falls away as well — you extend your hand again, curl your fingers like you're shielding a small, shivering flame from the soft brushes of the wind.
The stars shine, just out of your reach.

Summary
You were finally getting your life back on track. Juggling college courses and a new job, you were slowly but surely rebuilding from the ground up, convinced the worst was behind you. That all changes when a magical summons you can't refuse rips you from your world and drops you into a house filled with powerful, skeletal monsters who despise you before you’ve even said a word.
To them, you are the arrogant and careless human who shattered the soul of their dearest friend, the gentle mage Lyra. They see you not as a person, but as a living tool—a magical "key" they require to heal the damage you supposedly caused. Trapped in a multiversal nexus with no way home, you must navigate a gauntlet of relentless animosity and suspicion.
Every word you say is twisted, every action is judged through the lens of lies you don't even know have been told. How can you survive in a home that isn't a home, surrounded by enemies who believe they are the heroes? And how can you prove your innocence when the true manipulator is the very person they've sworn to protect?

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

Summary
Living with skeleton monsters was supposed to be temporary. A law, a requirement, a way to smooth over integration. But secrets linger in the walls, a machine that hums at night, skeletons who call themselves cousins with stories that never line up, and a shadow you think you can only see. You keep telling yourself you could not see him. You tell your roommates nothing at all.
But lies don't last forever. -

Summary
You grew up in the Orphanage, waiting for the day you'd be chosen and taken to your forever home.
But that day never came.
Years passed, and you watched as child after child was picked out and whisked away, all while you quietly faded into the background. Eventually you stopped caring, and instead, you became like one of the staff members, helping out around the orphanage and watching over the little ones. You even got an apprenticeship at your local motorbike garage once you were out of school.
It really helped to build your independence
...Your 18th birthday was approaching after all, and everyone knew what that meant.
But that day never arrived.
Because at 16, the one thing you were sure would never happen… happened.
You were adopted.
And by 8 skeleton monsters of all people.
…
This... is going to be interesting.

To make sure Black doesn't kill you like he does in the game... yet you don't seem to understand the stark contrast of yourself vs the queen as the skeletons do... and if you aren't careful?

Summary
A mutation has spread across the globe when monsters were released, humans either dying as their bodies couldn’t handle it or mutated with the rest.
The mutation was simple really, a change of dynamics. Humans started taking more unusual forms, growing more than a few ears, eyes, arms, legs, shit even a head at one point. Or body morphing differently altogether. Turning into their worst nightmares.
Y/N being a young child at the time of the outbreak changed with the rest of her family, half of her family died or killed themselves resulting in her being an Orphan at a young age, left alone in the world as her body shifted and changed. Body becomes leaner, smaller…cute. Cat-like ears and tail sprouting from her body, legs breaking and reforming into back hind legs of a cat's, fur covering her legs stopping at her waist.
Not only that, but she is an Omega.
Of course she doesn’t know oh no no no blissfully unaware, well that is until an over caring human Frisk decides to visit the Orphanage dragging along her friend Chara. Whom in turn absolutely dreads the visit. Let's say…frisk was the door to meeting a rowdy group of skeletons…

Summary
"O brawling love! O loving hate!
O anything of nothing first create!
O heavy lightness, serious vanity!
Misshapen chaos of well-seeming forms!
Feather of lead, bright smoke, cold fire, sick health!
Still-waking sleep, that is not what it is!
This love feel I, that feel no love in this."
- W. ShakespeareYou are a simple woman. You enjoy a simple life.
The universe, however, has decided you no longer get to live in peace.
Suddenly you find yourself face to face with an abomination, the likes of which defies the very nature of reality as you know it.
That might have been a little harsh, but then again, what else would you call a living, breathing skeleton?In the back of your mind, you had a creeping feeling there is a lesson to be learned in all of this.

For fifteen years, he's raised Papyrus.
Not even counting the time loop.
And now some pretentious ancient bones want to have a say?
Oh hell no.

Said "ancient bones" are mortified.
How were they supposed to know the short depressed skeleton was barely two decades old?!

Summary
The Fazbear Entertainment Warehouses were supposed to be abandoned, just full of old material from a failed business. People talk about weird noises or events happening there. Apparently it’s super haunted or something. Cash doesn’t really believe in “human ghosts”, it’s hard to when he knows actual ghost type monsters. Yet the rumors surrounding Fazbear Entertainment and what is being stored in those warehouses are too good to ignore. Maybe there really is something supernatural taking place. Regardless of the existence of any supposed ghosts, it’ll make a great video for Cash’s youtube channel. Anything for content! So he drags Stretch, Wolf, and Coffee with him and they set out to film a ghost hunt.
It was supposed to be fun.
There wasn’t supposed to actually be a ghost.
