Summary
Kranion always knew that you were his one and only, sure you didn't know of him- only his name which was permanently etched into your right forearm. Just like how your name was permanently etched into his collar bone. His soul always knew, been watching you from afar ever since your own mark came alight. At the age of 20 (your 24 now) your own mark and his own came to your respective bodies.
The only issue? Kranion is the demonic embodiment of Glutton, and you? You're just a measly little Human.

Summary
OneShot series with a Demon AU of Horrortale!Sans x Reader. Originally was gonna be a multi-chapter fanfic but I decided to do multiple one shots with the story progresses due to not knowing how to go about making the story cohesive.

Summary
If someone had told you that you would be a housekeeper to a skeleton in the future, laughing in their face would've been the least you would've done.
But stranger things have happened.
Like the fact that two more skeletons showed up and threatened to ruin the peaceful routine you had settled into.

Summary
You have had a tough life that has left you scarred and untrusting of others. Growing up in a mage family obsessed with power and ensuring their lineage, you are the black sheep of the family, possessing a green soul of kindness and excelling in healing and growth rather than the combat magic your family specializes in. Trapped in a loveless relationship with a controlling, abusive partner chosen by your family to ensure a 'proper' match, you live in fear of triggering his anger, often resorting to your magic to heal yourself. Every aspect of your life is controlled by someone else, leaving you resigned to survival and scraping together what happiness you can.
What you could never foresee is the way a miserable night out with your fiance would lead you to a drunken one night stand with your soulmate.
Nor could you predict you would have 9 more soulmates out looking for you.

Summary
New City. New neighborhood. New Neighbors. New Job. New friends. New life.
You wanted all this and more when you moved to Ebbot city, hoping to escape everyone and everything. Freedom was the only thing in your mind's eye. And, freedom was fucking amazing, for the first few days, but then you met an army of skeleton monsters and their bat-shit crazy, absolute psycho, probably an escaped asylum prisoner girlfriend Rachel. Lovely name for an absolute dumpster fire of a woman.
But, she wasn't any of your business, so, as long as you kept your head down and carried on with your life, she wouldn't become a problem. And, for a while, she wasn't, but then you saw just how horribly she treated her 'boyfriends', and you knew you couldn't play the role of the bystander any longer.
Knock Knock, Rachel, say hello to your new neighbor.
