Black Coal use to be a peaceful society, other than the fact they distroyed villages that couldn't pay bills. Kiyoko once visited this village and put an end to it.
Today, the cheifs great great great great great grandson/granddaughter rules a company called Black Coal, they want to destroy cities and build their company higher. Someone needs to stop them from this madness they call, business, and of course, The 8 Stones will have to take care of this problem!
