English title: Starkiller: Hearts Queen (Stellar Killer: Queen of Hearts)
In 2066, after years of pandemics and nuclear war, the world's population has plummeted to 600 million. Global wealth has been monopolized by capitalists, and the world has been unified under the Earth Federation government. The gap between rich and poor has widened further, while the capitalist class recklessly squanders Earth's resources. The greenhouse effect continues to worsen, and the environmental damage has become irreversible. A string of disasters has led to plagues and famine ravaging the world, bringing humanity to the brink of extinction... Forced to fight over resources, people have begun killing one another. They even foolishly launched a global nuclear war, whose fallout devastated Earth's entire ecosystem. Humanity continues to die out in despair.
In a wasteland world gripped by nuclear winter, the Galactic Empire, which rules 46 first-level civilizations in the heart of the Milky Way, takes complete control of Earth and divides it into 12 districts. Humanity is oppressed and enslaved by an alien civilization. Yet humanity has not fully submitted. Backed by alien resistance forces, Earth's Celestial Organization, <Starkiller>, challenges the Galactic Empire... A cataclysmic war spanning the entire universe erupts.
