A young catkin finds herself stranded on an island without any memories of how she got there, or who she was before. With a lack of humans in the area and monsters looking to turn her into a quick snack, she has to do everything in her power to survive or face being brutally mauled to death. Thankfully, the strange System that she woke up with seems to be just the thing that can let her survive, and turn the tables on the monster, giving her the chance to turn the tides of survival and trample over the world with impunity.
