Genre: Sci-Fi, Fantasy
At a unspecified point in the future, the Earth dies. Then, a genius engineer only known as “Y” manages to revive the Earth using only gears and clockwork. Thus the world is renamed “Clockwork Planet”, with cities being built inside the planet’s gears. A thousand years later Naoto Miura, a student and lover of machines living in the Kyoto gear, finds a crate has crashed through the roof of his apartment. Inside the crate is a coffin containing the broken body of an automaton. Using his superior sense of hearing, Naoto fixes the automaton, who is named RyuZU YourSlave, who reveals she has been broken for over 200 years. RyuZU promises complete loyalty to Naoto and the two become close. Later they meet two people trying to find RyuZU: Dr. Marie Bell Breguet, the youngest person to become a “meister”, a group of master engineers; and her bodyguard Vainney Halter. A month after their encounter, all four appear in Akihabara, Tokyo, having now become the world’s most infamous terrorists.
RyuZU is an automaton that “Y” left behind. She’s part of “Initial-Y series” and was manufactured about 1000 years ago but was broken 206 years ago and has been in non-functional state ever since. After Naoto repaired the failure inside her that nobody could fix, she treats him like her own master. Contrary to her beautiful appearance, RyuZU has an incredibly bad mouth. Her supreme command is “Tsukishitagaumono (your slave)”.
Naoto is high school student and a machine otaku. He has better hearing ability than other people, which is why he wears headphones with noise-canceling ability. Naoto isn’t interested in human girls, but he is interested in RyuZU who is an automaton.
