Summary
Kris, Susie, and Ralsei were a group of three friends who didn’t think anything interesting would happen to them anytime soon. However, when two human children suddenly appear in Hometown, both very hesitant to share their past, things might just get more interesting than anyone previously thought.
This is my first proper fanfic so please excuse me if it's bad.
Will have inconsistent updates.

Summary
Twin Runes es un AU cómico en su mayoritariamente alegre centrado en los universos Deltarune y Undertale. Una fuerza desconocida ha provocado que aparezca un punto de conexión entre los dos universos, lo que hace que Frisk y la molestia fantasmal Chara tropiecen en la vida de Kris en uno de sus muchos reinicios (para gran disgusto de Kris). Se produce un caos que rompe el juego.
La traducciones del "los pájaros y abejas" hasta el "No sirve pa' nada" no son mías. Del resto de traducciones si son de mi autoría

Summary
Once upon a time many centuries ago, the world was ruled by two species: Humans and Monsters. Both of these creatures thrived together using their special talents to help one another. That was until the humans declared war on the monsters out of the blue. This led to the monsters to be banished beneath a mountain.
But rest well when I say the humans suffered their karma. Without monsters they soon lost their magic, along with their way of life. They developed their own powers called quirks, with this power came the raise of heroes and villains. Quirks were quick to spread until only 20% lacked them.
It wasn’t long before magic and monsters were reduced to legend. This led many to climb the mountain to see if the legends were true, only to never return. This was because of the heartbroken monster king who put a bounty on every human who fell.
When the last human fell, the monsters were ecstatic. Finally they’ll be free to wander the surface and feel the sun and the rain again! But unbeknownst to them, they have become even more trapped than they had before. With each reset the monsters were forced to live the same day over and over without anyone knowing ... .Well, almost everyone.

Summary
The life of a conscientious, straightforward young person is full of trials, especially in an insincere world with insincere people, bigots, child murders, bigoted child murderers, Tumblr sexy 'men' worship, algorithms, and people who don't have the brainpower to resist algorithms such as YouTube monetization and begging for subscriber bells.
And so, Frisk attempts to live enjoy life on their own terms, come hell or high water.

Summary
"They’re sitting in a bed of golden flowers somewhere far beneath the earth, and, as far as they can tell, for better or for worse, they’re decidedly still alive."
_ _ _ _ _
Frisk climbs a mountain and inadvertently awakens an ancient terror sleeping beneath the flowerbed they land on when they fall. If by "ancient terror" one assumes the less-popular definition of "annoying narrator-ghost princet of monsterkind who is now, unfortunately, permanently stuck in their head."
Chara doesn't want to be awake. They especially don't want to be helpless in the back of a bloodthirsty human's head, watching them ruin the only home they've ever known with no power other than their voice to fight back with. Luckily for them, that's not what's happening at all. Unluckily for them, they may have to re-evaluate a few things about their worldview. Which, for someone as set in their ways as them, is not an easy thing to do.
(Then there's the matter of the weird flower, Frisk's unusual powers, and the Longest of Long Days the underground has ever seen.)Chara & Frisk no player AU true pacifist. Updates semiregularly from ~80 chapter backlog!

Summary
You fell.
Which honestly sucks ass.
You had been feeling weird, in your chest, for a while now.
Not sure how you ended up in a world of monsters but you do know one thing.
Your chest is pulling you towards something. And the closer you get, the more whole you feel.
You just hope you don't have to keep dying to get what your SOUL desires.
