Long ago, humans evolved into beasts and then into something else. Carnivores with fangs and claws, herbivores with physical strength and athletic ability, and the lowest class of humans with nothing. Butch is a young girl who is forced to work as a maid in a beastman's mansion to pay off her debts. Her life is about to change completely due to a "beastification experiment"! Carve out your own future with your own fangs and claws! A rebellious beast fantasy set in the beastman world!
