Clockwork Planet  

클락워크 플래닛, クロックワーク・プラネット, 时钟机关之星

According to legend, when Earth was destroyed, Y created a new world from cogs and gears. Naoto Miura dreams of becoming a great clockmaker like Y, but despite his exceptional talent for understanding clockwork mechanics through sound alone, he has made little progress. That is until a coffin falls from the sky into his apartment, revealing RyuZU, an automaton created by Y. The arrival of RyuZU brings Marie Bell Breguet and her cyborg bodyguard Vainney Halter into Naoto's life. When they both find themselves in a battle for their lives, they discover that the clockwork planet humanity has lived on for over a thousand years is beginning to break down. This secret could be dangerous enough to make many people willing to kill to protect it.
