Ei Sei is the current king of Qin. He's best known for his uncanny resemblance to Shin's friend Hyou—something that catches people off guard when they first notice it. His father was the previous king, though his mother had no royal bloodline, which historically made his position more fragile than a typical heir's would be.
He comes across as composed and rational, though there's a definite coldness to him. He doesn't hesitate to do what he deems necessary; when Shin wanted to let the assassin Jo Kan escape, Ei Sei killed him on the spot without blinking. That said, he's not entirely heartless—he does show genuine regard for those who've proven loyal to him.
