Our story is set in the third century BC in what is now known as Qin Dynasty China. The death of Shin huangti, the first leader strong enough to unite the warring states, has led to uprisings against the Qin hegemony in each territory. Out of all this chaos, Kou U, a general from the Chu State, emerges as a supreme warrior. Together with his uncle, Kou U has seized control of Kaikei. From his newly-acquired stronghold he begins to raise an army.
