In 8 years ago, Western Civilization arrived in 19th century Japan. The country was introduced to mechanized dolls and steam-powered machines. A group known as the Wind Gang believed in using their creations violently to usher in a new era of industry. They attacked and destroyed a peaceful village inhabited by a young doll user named Hiwou. Along with his friends, Hiwou escaped with a giant doll called Homura. Now, Hiwou seeks to locate his father so that he can aid in defeating the Wind Gang and restore tranquility to Japan.
