With Sam having his soul once more, and his memories of Hell locked away behind a mental wall, the Winchester brothers are attempting to track down the Mother. With Castiel preoccupied on stopping Raphael, the brothers along with help from Bobby seem to be working this case alone. However, while their attempts to track down the Mother are so far unsuccessful, they didn't expect to be involved in another case that becomes much more than they first thought. This story is an Undertale meets Supernatural type of thing. It takes place somewhere near the end of season six in Supernatural, and a few months after the true pacifist ending in Undertale. All of the monsters are free, though Frisk has chosen to not accompany them. I hope you all enjoy this story, it may take me a while to post chapters so hang in there X3. I apologize for any errors, grammar or errors with character's personalities and the plots of both universes, this is my first lengthy story and I am not a very experienced writer ^^'. Please feel free to leave any comments and critique for me to better improve my skills and the story, everything helps!

I have taken the liberty of writing the entire script of UNDERTALE. Written in British English. I have looked around and I can only find certain sections but I am writing the entire transcript of the game into a word document. This may be a massive text dump or it may be separated into chapters. I am not sure on which. For now, it will be separated into different places/battles. This will include all phone calls at the end of the game, the major routes (Pacifist, Genocide), and maybe a few neutral routes.

Alone in a condemned world where monsters and humans fight for power constantly, Y/N survives off of the wood's riches and the small scraps of shelter she can find in ghost towns. Allies and friends have come and gone during the war, either killed or have parted ways. It's not all that bad. She could be dead, after all. One afternoon when shipments from the Human Capital come on a train, she meets a mysterious stranger who saves her life. He's a monster, no doubt, a skeleton to be exact. Y/N is intrigued by the monster and decides to follow him into the next town over where he disappears into an abandoned warehouse. Y/N follows him in only to be pinned to the wall for questioning. After answering all his questions, introductions are made and Y/N learns that the skeleton's name is G. Y/N likes G despite his hateful nature and somehow convinces him to let her come along on a quest he's taking to save his brother from the Monster Capital where they took him for war. After surviving assaults, the government, and Mother Nature herself, Y/N and G start to form a special bond that neither of them wants to break. But when everything goes wrong and neither of them is strong enough to prevent it, Y/N finds that the capitals that she had always hated are far more sinister than she could've ever imagined.
