Petrified for five hundred years, Willem Kmetsch wakes up to find he has nothing left in a world where his kind is extinct-a world that sees him as unnatural. <p> To survive, Willem takes on a job as a weapons caretaker only to discover that these are something more-they're young leprechaun girls with the power to wield the mighty "dug weapons," the only hope against the seventeen beasts. And they're ready to die for their purpose. A fact that doesn't sit right with Willem and leads him to care for the girls, especially the eldest, Chtholly. Soon, the girls begin to develop a desire to live and love until suddenly, something within Chtholly breaks. <p> What happens when weapons develop a will to live, and what will happen to the world they're meant to save?
