Summary
A human child by the name of Frizk climbs the forbidden mountain, Mt. Ebott. Her goal? To go to a new world in order to live a new life. While she expects an isekai, she instead falls into the Underground where she meets a talking flower. This flower has the ability to seemingly alter time. To the human's surprise, the flower is helpful and friendly. Now in the Underground, Frizk wishes to live a life amongst monsters. To do so, she must keep her human identity a secret.
Unlike the Underground that you readers may know, this Underground is different. In it exists a young Boss Monster, the child of the King and Queen who are still together.
This young Boss Monster wished from her youth to make the Underground a better place. In order to accomplish this, she became the Royal Scientist and started to improve the lives of monsterkind. However, in doing so, she ended up often overworking herself. Monsterkind treated her as the pride, joy, and second hope after the long-distant passing of their first prince, Asriel. Due to her habits, this Royal Scientist Princess lives a solitary, lonely life.
Will the two be destined to meet? Or will they continue on with their predicament, their lives never crossing paths?

“Sorry.” Kris spoke, automatically.
Asgore, ever kind, doesn’t care at all. “It is no matter. Did I remind you of your father?”

After Basil’s death, Sunny runs towards his home in an attempt to end it all, but Aubrey follows him and she prevents him from dying. Sunny tells her the truth and now they have to face it together.
After moving, they find themselves camping until something happens and now the two will travel together in order to escape the Underground filled with creatures that were only believable to see in fantasy books.Notes:
the Undertale tags are there because I want to make an Omori x Undertale fanfic, but there won't be anything related to Undertale during the first two chapters except for some references to Mt. Ebott and its legend, but around Chapter 3 or 4 onward, the Journey through the underground will begin!
So stay PATIENT!Series

UNDERTALE: Surface Tension by Seraph_UTST
Fandoms: Deltarune (Video Game), Undertale (Video Game)

Summary
A long time have passed since Frisk led monsters to freedom. Now sixteen, Frisk finds themselves presenting that very story to a class full of humans and monsters
You'll meet Frisk, now sixteen, free from your control, and still carrying the weight of their choices, doing their best to bridge two worlds with kindness and honesty.
Seraph, your new vessel, a quiet, artistic boy of unknown origin who lives with Gerson and looks up to Undyne like a big sister. His drawings are oddly prophetic… and sometimes, he can feel what others feel.
Lapin, a rabbit monster new to the surface and overwhelmed by the change... maybe even a little lonely.
MK, once known as Monster Kid, now a confident chatterbox still idolizing Undyne (and maybe trying to figure themself out).
Vesper, a bat monster with a protective streak and a soft heart they try VERY hard to hide.
Aiden, Seraph’s loud, loyal best friend, a jokester who’s like a brother to him, always ready to stir up trouble or crack a smile when things get heavy.This is a story about what happens after the story ends. About choices, big and small, that shape who we become.
And sometimes… it gets weird.

Diving for Justice, Freedom and Managed Democracy by Dangeresque_On_Ice

Summary
The Monsters were dead.
They must have been, the Federation of Super Earth had said so; annihilated during the Great Galactic War along with all the other threats to Managed Democracy. So Clover was understandably confused when he set out to find the five missing Cadets only to discover a whole society of Monsters sealed underground.
What’s more, these Monsters were nothing like the tyrannical, Freedom-hating killers history had portrayed them as.
Things just weren't adding up. But why? It’s not like Super Earth would have lied, right?

Summary
It's been three years since you fell into the underground and found a family among the monsters of the Ruins. You love your life here with Mom, your ghost buddy Blooky, your prickly friend Flowey, and the host of Ruins monsters who have accepted you as their own, but things can't stay this way forever. Your friends deserve to see the sun, and there's a prophecy to be fulfilled and a barrier to be broken. Your determination pulls you onward.
The only trouble is that you'll have to make it through an underground full of monsters clamoring after the red SOUL in your chest, and each day as circumstances become more dire they lose a little more hope. This is a more desperate underground than the one you landed in. The odds don't look good for one pacifist child with a stick.
Of course, you aren't completely outmatched. You've spent the last three years training for this moment, and you don't intend to let anyone hit you.

Living in the Wild East with Starlo was great. For the first time in a long time, you found yourself truly happy. It seemed like coming to the Underground was the best decision of your life.

I turn my fic that originally started out as smut oneshots into a fleshed-out story with angst, fluff, and yes... still more smut.

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
