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...

Constable Rail, the rookie agent of ACCA's Badon branch, has a profound dislike for elite agents in ACCA headquarters and has it out for Jean. Meanwhile, feeling watched, Jean asks for his friend Nino's help. With rumors of a coup d'état circulating among the upper echelons of ACCA's hierarchy, Chief Officer Grossular announces at the Five Chief Officers meeting that he has obtained credible information about the coup.

Back from his Suitsu audit, Jean asks his supervisor, Owl, about the status of his transfer request. Unfortunately, it seems unlikely to be approved anytime soon. As Jean leaves to go home, Chief Officer Lilium offers him a ride, where he tells Jean that he is being watched. Jean soon leaves for Birra District for yet another audit, where he comes to learn a troubling truth...

Jean arrives in Furawau District to conduct his final audit this round, where he receives the red carpet treatment from the Lilium family. Furawau residents are full of cheer, and their land is plentiful with blooming flowers, but Jean cannot avoid sensing invisible forces at work under the surface.
