In AD 200X, World War 3 begins?

In AD 200X, World War 3 began. All of the Earth's cities became targets of bombings and were bathed in frightful red flames. Half a century has passed since then. The contaminated former epicentre is still isolated from the city of Tokyo creating a hole in the middle of Japan commonly known as the Black Spot. As time passed, people began to inhabit this wasteland. They were deemed unnecessary by those who lived in cities. Among these people were the ones who could command strange abilities - fire, wind, gravity... they had the ability to control these supernatural powers. Thus, those who possessed Fragments were regarded as...THE NEEDLESS!
