"Naoto is a brilliant amateur mechanic who spends his days tinkering with gears and inventions. And his world is a playground--a massive, intricate machine. But his quiet life is disrupted when a box containing an automaton in the shape of a girl crashes into his home. Could this be an omen of a breakdown in Naoto's delicate clockwork planet? And is this his chance to become a hero?"--Back cover.
