In a world filled with manipulation, crime, and violence, there is nothing that could be more dangerous. Well, maybe aside from the fact that supernatural beings exist. Not only that, but they also co-exist with humans. Different from what people first thought before they found out about these beings, everyone naturally blended together. Groups were formed, each consisting of different species, be it vampires, hybrids, superhumans, or casters. After the Coalesce Era (the era where various species emerged and everyone blended together), the world that seemed to be too dangerous, became much more perilous than the people thought. The groups formed are now called called "unions", as different species unite and clash against other groups aiming to be on the top and be the most powerful among all.

30 years later, " The Association" was formed in aims to control the outrageous activities and destructive actions of the unions. They implemented a system which limited the unions' freedom and reduce the destruction they are causing for the citizens. To avoid an outrage from the unions, they created an event held once every 6 months in which the unions can compete and battle against one another and name the most powerful union among all, "Dystopia". With that, the world started to revolve around "The Association", "Dystopia", and unions. But, behind all that, problems which are far more bigger than everyone thought they are ceased to exist. Covered by the events between the three significant and most important forces, these overlooked problems will bring chaos once again, if continued to remain unnoticed.
