This story is about monsters and humans. I got inspiration from my all time favorite game "UNDERTALE" thus the title hehe. So this story basically surrounds SANS the skeleton, the human, and 6 more humans and monsters. I will of course name the human as Astrid. I also named one or two humans with my imagination. As a disclaimer i might add that in a few chapters, there might be chapters which can contain disturbing content. A quick summary of the game: Once upon a time, monsters and humans were considered equal. When one day a war broke out and as the strength of human souls were stronger than that of monsters, they were banished underground forever by 7 human souls. The monsters could only get out of the underground with 7 human souls. If humans fell down the mountain those humans would have to either kill the king to get out or be killed by the king who would store the soul of the human until more souls are gathered and can leave the underground. That is the original content of the game but i will change a bit here and there depending on my liking. LAST BUT NOT THE LEAST.... enjoy :)
