In the not too distant future Umbra City was devastated by an explosion that genetically altered hundreds of citizens caught in its path, creating a wave of genetically altered mutants and beings with incredible abilities. Beings from henceforth called "Deviants".

 

The neighborhood surrounding ground zero, now nicknamed "Zero Zone", has become home to the altered and a lawless cesspool of prostitution, gang disputes, and super villainy. The rest of the world and it's heroes turn a blind eye to the Zero Zone but it does have one dedicated protector, and her name is Attack-Girl.
