Hyper Hurricanes created concurrently all over the planet wreaked catastrophic devastation in the year 2010 AD. Five billion people died, reducing the world's population to three billion. Existing economies and militaries were destroyed. Countries were frozen in solid ice, plains fell beneath oceans, and the globe was drastically altered. Human society has entered a period of chaos. Outside of these economic zones, poverty thrived, and slums were common. The ruling elite referred to themselves as Logos and maintained their power via force of arms. The destitute are referred to as Revenus, and they are banished to reside outside of the special economic zones. Since then, a lot of time has gone. Katsuragi Jo and Tsurasawa Jin flee Phantom, a group formed to keep an eye on Revenus and repress rogue Logos components.
