Summary
Skeles (commonly referred to as Sanses) are playful, happy little pets who love to make their owners happy. Edge is delighted when he meets a very special Classic-type Sans named Sans (okay, not very creative) but is disheartened to learn that his owner, Papyrus (while great at showing his love) isn't giving Sans what his species needs to live long and healthy lives. So, Edge takes it upon himself to educate Papyrus on proper Sans handling, as well as letting him know that his Sans needs to breed soon. Conveniently enough, Edge has his own Sans (a willful Fell-type named Red) that would be the perfect mate. That is, if Sans wants to.

Summary
Nightmare knew he was not the best in the Multiverse.
Hell, he was not even good.
He was the God of Negativity, a title that followed him like a curse carved into his very bones, and it made perfect sense that someone like him would end up completely alone.
Or: Nightmare is lonely so he ends up recruiting Killer, Dust and Horror all based on misunderstandings.
With fanart!

Summary
Dust was on his couch after yet another long day at work when he saw a blinding flash of light in his garden. Getting up he slowly approached the bay window to take a look outside... and saw four strange skeletons dressed as a viking, a noble, a knight and a Roman yelling in foreign languages at each other.
He didn't know why he opened the window nor why he invited them inside, but he did, and by doing so he sealed the beginning of a very weird adventure with his four new roommates...
Dust - Modern Time, speaks English
Horror - Scandinavian Viking, speaks Old Norse
Killer - Ancient Roman, speaks Latin
Cross - Medieval Knight, speaks Old French
Nightmare - 17th cent French Noble, speaks Classical French(Cross-posting on Tumblr ! @/mikimakiboo
Basically a story about the boys coming from different time periods and time traveling together
Short chapters but it allows me not to burn-out too fast :')
Also, time being what it is, I should specify that I did NOT use AI for anything in this story, the languages all come from long researches to translate word by word in some cases, I did it all myself without the use of AI)

Summary
Error wakes up in a game he never chose to play—Until The Last Breath, a brutal survival world hidden between life and death. The only players? People trapped in comas. The only way out? Win.
To survive, he must fight through deadly floors, forge uneasy alliances, and follow three unbreakable rules:
[ 1. GAME OVER means death, both in-game and in real life. ]
[ 2. Artifacts must be crafted from Fragments found throughout the world by a Player. ]
[ 3. Reach the final floor before the chronometer runs out… or fade away forever. ]
There are no second chances. No resets. Just the questions: can Error and his team beat the game before it beats them—and can love survive in a world designed to tear everything away?

Summary
(rewrite)
He flinched hard as a skeletal hand bigger than his torso came to lay on his skull, gentle in all the ways it shouldn’t have been. It simply laid there, claws careful not to nick him, before warm breath came next to his head.
“Good boy. I will take care of it.”
Sans blinked, tears dotting his sockets as it finally backed away, staring down in him with an unknowable expression.
“You… you will?” Sans asked, voice trembling, quiet and meek. It stared for a moment before nodding once.
“Yes. But it will not be pretty. Go to your bedroom, shut and lock the door. Do not come back out until I tell you it is okay.”
