Dowa kingdom is comprised of thirteen autonomous districts. Their peace is maintained by a single massive organization, ACCA. Deputy Chief Jean Otus of ACCA Headquarters Inspection Department is in charge of conducting ad hoc audits of the thirteen district branches. As he is about to head to Famasu District, however, ACCA's Five Chief Officers announce that the Inspection Department is to be shut down due to its perceived obsolescence in peaceful times...

Various wheels begin to turn at ACCA Headquarters as the prospect of a coup looms ever closer. After receiving yet another cigarette in Yakkara, Jean heads to Pranetta where only rocks and sand can be found and the denizens live underground. Despite living under such harsh conditions, the people of Pranetta are full of hope that their mining industry will succeed.
