It has been collected in ten "tankōbon" volumes. An anime television series adaptation by Xebec aired from April 6 to June 22, 2017. Plot. At an unspecified point in time, Earth collapses. Despite it being almost inevitable that humankind would die out, a genius engineer known only as "Y" manages to rebuild Earth entirely with gears and clockwork mechanisms, renaming it "Clockwork Planet". 1,000 years later, original cities of Earth's countries are flourishing  inside the planet's surface gears. Naoto Miura, a high school student living in Grid: Kyoto who is in love with mechanics, is dragged into a world crisis when a mechanical crate crashes into his apartment. There, he meets RyuZU, a broken automaton who is part of the Initial-Y Series, a series of automaton created personally by Y himself. Using his superior sense of hearing, Naoto fixes her in three hours despite RyuZU having been broken for 206 years as nobody was able to revive her. Promising loyalty to him, the two are eventually found out by Dr. Marie  Bell Breguet, a princess of a noble family and the youngest person to become a master engineer in an international separate government organization "Meister Guild", and her automaton bodyguard Vainney Halter. With the faulty Core Tower, a central tower in every Grid city that controls its gear functions, Naoto pinpoints the problem with his sense of hearing alone in ten minutes, fixing it along with other engineers of the Meister Guild and thwarting the government's attempts to purge the city and destroy lives. As the government's illegal technological experimentation is still at large, the pairs join forces to  carry out justice and prevent further purges. A month after their encounter, all four appear in Akihabara, Tokyo, having become the world's most infamous terrorists in their quest. Media. Light novels.
