Thinking nothing of it, Willem accepts, but he soon realizes that these weapons are actually a group of young Leprechauns. One day, he is tasked with being a weapon storehouse caretaker. He lives a life of loneliness and only does odd jobs to get by. Together with the other surviving races, Willem takes refuge on the floating islands in the sky, living in fear of the Beasts below. Willem awakens 500 years later, only to find himself the sole survivor of his race as mankind is wiped out.

Putting his life on the line, Willem Kmetsch leaves his loved ones behind and sets out to battle a mysterious monster, and even though he is victorious, he is rendered frozen in ice.
