Five centuries ago, when humanity was swallowed by the tides of extinction, Willem Kmetsch alone endured—preserved in stone, only to awaken into a world that had long moved on without his kind. Reborn into this unfamiliar era, he takes up the role of Second-Class Technical Officer among the floating islands, tasked with maintaining sacred blades and watching over fairy girls condemned by fate to be used as living weapons. Though his body and soul bear the scars of a former quasi-hero's battles, Willem refuses to let despair define him—instead pouring every ounce of his warmth and sense of duty into building something precious for those who march toward death: a place that feels like home.
