Synopsis
Earth died. A genius engineer known only as "Y" rebuilt it using nothing but gears and clockwork. A thousand years later, high school student Naoto Miura found a crashed crate in his apartment containing the broken body of an automaton named RyuZU, inactive for over two centuries. Naoto fixed her using his uncanny sense of hearing. She pledged her complete loyalty. They soon joined forces with Marie Bell Breguet, the youngest master engineer in history, and her bodyguard. A month later, all four were the world's most wanted terrorists.
