The power to reset the timeline, and the determination to move forward no matter what the cost. These are the two things that keep a young girl moving forward in the mysterious world of the underground. She could be the key to their salvation, but would it all be worth it? Especially if the one person that matters most remains trapped and alone. (I don't own Undertale.)

After getting to the surface countless times Frisk finally decided to tell Sans and Alphys what would inevitably happen, though that's when a desperate plan was suggested.

The little Sansy is odd, even for a Bitty Monster. He just wanted to escape his terrible reality... Turns out, he had a quirk. A random Bittybones request fic off my tumblr for reblogslol4545. And for anyone else who might enjoy it. Genderless OC called Y/N. -I mean 'Yin'. TW for blood (stains on clothing), some minor swearing, and some unfortunate rats.

Sans is afraid to dance, Papyrus is worried, and frisk want to dance with him at least once. The rest of the family is happy to help.

What if the six fallen humans who died before Frisk never died and instead joined Frisk on their journey through the Underground? It all seems good... aside from Frisk.

Pero, aún así... con todo el dolor y el sufrimiento que sus hermosos ojos ocultaban de él, aún había algo que decir. "¡Pero eso no significa que odie estar contigo, Frisk!"
