The genocides never seemed to end, until they did. Something happened, something that threw Sans into another world where he must adapt. All while trying to stop a killer and save his family and friends. Here is the rewritten version of my first story. This fic contains swearwords, violence, blood, death, intrusive thoughts, murder/ attempted murder, If you are sensitive to this sort of thing then I recommend you proceed with caution. *I do not own Undertale or Bnha in any way. *The cover art is drawn by me.

(Disclaimer : Badly written English will be in the story.) Frisk freed the monsters at once, but there's still someone underneath that huge mountain. Frisk also freed that someone, promising her that life will be better at the surface, and whatever things the future holds from the girls, Frisk will be the sister Chara always needed. And at the first day at the new school, the sisters met someone ... special, at least that's what Chara feels. Story started the 02/10/2022. Story ended the 03/01/2023. Inspiration taken from : Fallen Determination by Red Knife

After commencing the neutral genocide path, "(Y/N) (L/N)" regrets slaying all the monsters and decides to start again, with a new objective in mind: Free all monsters permanently. But, will he be able to save EVERYONE?

Complete! The player has just finished fighting sans and has left him to die. As sans turns to dust he sees a flash of light before everything goes black. He then wakes in a new world. Note: I don't own undertale bnha or the character in it nor do I own any of the art in this, this is just a fan fic that I decided to make.

The Undertale Genocide Route is happening, but a new card has joined the deck: Finn, a quiet kid with a love for stuffed animals who falls into the Underground soon after Frisk. At first, it doesn't seem like there's much Finn can do, until they discover their superpower: the ability to transform huge piles of white dust back into the monsters they used to be. It's up to Finn to stop the murders once and for all and free both Frisk and Chara from the control of the player - but will they succeed? Or will they fall prey to the same fate themself... This is my first time writing a story here and I have no idea what I'm doing xDD Criticism is welcome :3 Oh! Also, I made the cover myself. In case anybody was wondering. This is the first book in the little Undertale trilogy I have going on :D If you're interested, you may want to follow up with the second book, UnderAsriel! It may seem at first like it has nothing to do with this but I promise it all ties up in the end, and it's essential to understanding the third book.

I'm bad with descriptions

One day you go play in the forest with your best friend but both of you fall into a hole and after that, you will experience a journey that will change your life forever. This story will contain (a little) explicit language, violence, and fantasy violence, and in later chapters sexual content. Original artwork used for the cover by: KyoBlack_Haru
