The manga based on the light-novel series by Yuu Kamiya, creator of No Game, No Life—and now a brand-new hit anime series! Naoto’s a high school dropout and brilliant amateur tinkerer. He lives in a world that has been so over-exploited that the entire surface has become one vast machine. When a box crashes into his home containing a female automaton, it’s a harbinger of change that will rock the entire globe, and give Naoto his chance to be a hero.
