Pandora in the Crimson Shell Ghost Urn

In an age when large-scale natural disasters frequently happen all over the world, when cyborgs and autonomous robots are beginning to appear on the market in technologically advanced nations, and major world powers compete for technology and resources, the divide between rich and poor grows and the future for the poor looks bleak. In this transitional stage, everyone wanders around in a self-indulgent daze and the way out isn't clear... This is the story of how two cybernetically enhanced girls meet.

In the year 2031, an experimental energy device known as the "Quantum Reactor" is created to help alleviate the problems stemming from Earth's dwindling fossil fuel reserves. Unfortunately, the "Quantum Reactor" goes out of control, exploding and bathing the world with unknown energies in an incident known as the "Shouryuu Crisis". As a result of the catastrophic environmental changes that follow, humanity is pushed to the brink of extinction, and strange new organisms - part organic, part mechanical - known as the "B.R.A.I." emerge. Seven years later, Leon Lau - one of the scientists at the center of the "Shouryuu Crisis", is living in the wilderness near Neo Shouryou, one of the last remaining human cities. Leon has entered into a "family contract" with Chloe Lau, and together the two of them research their own methods of combatting the B.R.A.I. threat.

In the near future, Earth has been devastated by an immense war. Haruka, one of the few survivors, lives in the ruins of Japan. Knowing no other survivors, she lives with five robots. Spike, the youngest robot, serves as her best friend, Cleric advises her, and Angela destroys her enemies. With Toriga, the world's angriest and least effective combat robot, and Reeves, the meanest-looking machine ever to wear a frilly pink apron, they protect her and search for other survivors.

In the year 2010 AD, Hyper Hurricanes born concurrently all over the world caused severe damage. Five billion people lost their lives, decreasing the world's population to 3 billion. Existing economies and militaries were wiped out. Countries were frozen under solid ice, plains sank beneath seas, the world was changed dramatically. Human civilization enters a chaotic era. Poverty flourished outside of these ecomomic zones and slums were widespread. The ruling class called themselves Logos and maintained their position by force of arms. They call the poor Revenus, who are exiled to live outside the special economic areas. Time has passed since then. Katsuragi Jo and Tsurasawa Jin, escape from Phantom, a force organised to watch Revenus and to suppress renegade elements of the Logos, taking with them a mysterious girl, Noto Sana. There are many who are interested in her, all with their own reasons.
