The change of demographics caused aging of population. The government belatedly announced a new measure to stimulate birth rate, however the elderly already outnumbered the young. With severe labor shortage, the government came up with a policy to immigrate the foreign workers. Soon the foreign labor force became the backbone of the nation’s infrastructure and formed mixed-race families among themselves. As the economy thrives, the racial intolerance and bigotry grow rapidly. Ethnic chauvinism of Nation’s “pure-blooded” and racism deepened, and the anger towards them soon grew to violence.
Now, a total war has begun between the CT-FORCE, who desires stability and maintenance of the status quo and the Free Rebel, who tries to attain their needs by force.
