Clockwork Planet is set on a world rebuilt after Earth’s destruction, where the legendary clockmaker Y created a replacement planet of gears, cogs, and intricate mechanisms. In this artificial world, Naoto Miura is a young boy who dreams of becoming a great clockmaker. Gifted with an unusually sensitive hearing that lets him understand machinery by sound alone, he still struggles to make real progress. His quiet life changes when a coffin falls from the sky into his apartment and reveals RyuZU, a female automaton forged by Y himself.
RyuZU’s arrival pulls Naoto into the orbit of Marie Bell Breguet, the gifted heir to a distinguished line of clockmakers, and her cyborg bodyguard Vainney Halter. Together, the three are drawn into dangerous conflicts as they uncover the truth that the clockwork planet humanity has lived on for more than a millennium is beginning to break down. As rival interests move to control or conceal that secret, Naoto, Marie, Vainney, and RyuZU are forced to fight for the fragile order beneath the gears before the system that keeps their world running falls apart.
