It has been nearly eight years since feudal Japan was visited by the first black ships of the western world. An uneasy treaty has been forced between the United States and the Tokugawa Shogunate. Resentment grows amongst the populace and a new sentiment spreads: "Revere the Emperor and drive out the Westerners!" Spreading almost as quickly are a number of clockwork and steam-powered devices. Manipulating these devices is an evil organization bent on conquering the nation and forcing a new industrial era, the Wind Gang.
A young member of a tribe of machine people, Hiwou, has recently discovered the gift of his heritage in the form of an ancient and powerful clockwork doll known as Homura. It is up to Hiwou, piloting the giant Homura, to stop the Wind Gang and avert the tides of war. This clockwork doll might just be able to change a bit of history!
