The ruins of the people's tranquility lie smoldering. Two thousand years of prosperity have come to an end, the Empire conquered at the hands of degenerate invaders. As what they once took for granted crumbles around them, its citizens nevertheless continue to strive for a better tomorrow, even as they are swept up in the tides of history. Miyaguni Akari, the final heir to the imperial throne, seeks power―for it is her absolute duty to eradicate her sworn foes and reclaim her empire. Tokita Soujin, a proud warrior without a past, seeks a lord―for the noble blade must be wielded in the name of fealty. Fate shall see to it that their paths will cross―and it is not the domain of man to know whether their journey shall end in despair or in triumph.
