   Summary

   Sent to climb the infamous Mt. Ebott on a dare, you suddenly find yourself lost in a world filled with beautiful women, a talking flower, and danger around every corner. Can you survive? A monstergirl novelization of the original Undertale, with lemons abounding every chapter and harem elements in the "No Mercy" path. Each chapter after the first will have a good and an evil version.
