Kris and the gang enter Undertale, mistaking it for the Dark World.
About
Long ago, two races ruled over Earth: Humans and Monsters. One day, war broke out between the two races, and the humans were victorious. The humans created a powerful magical barrier and sealed the monsters in a massive underground world beneath Mt. Ebott. Since then, humans have lived on the surface, while monsters have spent ages building their own society underground. While it is possible to enter the barrier sealing the Underground, it is impossible to leave. To completely destroy the barrier, a massive power equivalent to seven human souls is required. The souls of six humans who fell into the Underground in the past are currently kept by the King, who plans to collect more human souls to destroy the barrier and liberate the monsters. The Underground consists of distinctly different regions such as the Ruins, Snowdin, Waterfall, Hotland, and the Core. The path starting from the Ruins leads through Snowdin, Waterfall, Hotland, and the Core to the capital, New Home, where the barrier is located. Then one day, five individuals—Kris, Susie, Ralsei, Noelle, and Berdly—are caught in a mysterious spatial anomaly. When they regain consciousness, they find themselves completely cut off from their own world, crash-landed at the entrance of the ancient Ruins deep beneath Mt. Ebott. Only Kris is a human; Susie, Noelle, Berdly, and Ralsei are classified as monsters. The five begin their adventure knowing nothing about this Underground world.
