It's the year 3000, and the world has been turned into a mass of violence. What was once known as the beautiful Russia is now a worldwide powerhouse that controls all of Europe. North and South America have been ravaged bare by mercenaries and soldiers, and now serve as vast empty territory that has yet to be claimed. Islands have been taken over by those who are rich and powerful, entire countries now devastated by war. Only a few select countries still remain. Japan is one of those countries. Having been turned into a floating island, Japan spends it's days moving slowly away from Europe. But, even Japan is not safe. War has corrupted the country so fully that all is left are orphans: children with nothing to do but fight to survive.
