The residents of W City are all headless. They sense the world through sensors on their chests and communicate through generators in their abdomens. Thinking has become a forbidden disease. Headlessness is not only a physiological state, but also a spiritual symbol. Residents are indoctrinated with unified information, lose their independent thinking and emotional abilities, fear and reject any aliens (headed ones). The spiritual tower is the control center of the city, emitting hypnotic waves to maintain the "headless state" and monitoring everyone's thoughts. A hundred years ago, in order to end the years of wars caused by ideological differences, those in power built spiritual pagodas, ushering in the "Headless Era".
