Xiahou Xuan (onyomi: Kakō Gen) was the son of Xiahou Shang and a minister of Wei, and was a close childhood friend of Sima Shi (whom his sister Xiahou Hui married) along with He Yan. However, both Xiahou Xuan and Sima Shi started grow distant in the later years through their career paths, to the point where they were on opposite sides of the law much like He Yan. He was eventually executed by Sima Shi for plotting an assassination attempt on him in order to return power to Cao Fang.
