Kingdom
During the Warring States Period of ancient China (475-221 BCE), Shin and Hyou are war orphans in the kingdom of Qin. They hope to one day prove themselves on the battlefield. However, one day, a minister brings Hyou to the palace. After losing a power struggle, Hyou makes it back to the village, barely alive. Shin then meets Ei Sei, who looks a lot like Hyou. For now, he is the king of Qin, but he will become the emperor Shi Huangdi in the future.
