One of the Seven Fire Dragons of Wei. Known as a cold and ruthless strategist, he is the mentor of Go Hou Mei, the current Great General of Wei. Unlike fellow Fire Dragons Gai Mou and Shi Haku, he lacks physical prowess but excels in tactics using his powerful subordinate, Ran Bi Haku, as a devastating flanking force. He is characterized by his androgynous appearance and elusive, detached way of speaking. In the past, he sided with Shi Haku during the internal purge triggered by the conflict between Shi Haku and Tai Ro Ji. The resulting massacre left three Fire Dragons dead, nearly leading to Rei Ou's execution by the enraged King of Wei. However, through the mediation of Go Kei—the only Fire Dragon who did not participate in the infighting—he was officially declared dead and imprisoned instead to settle the matter. He remained in prison for 14 years but was eventually released due to a change in kings and the lobbying of Go Kei's son, Go Hou Mei. He possesses a youthful and beautiful appearance that belies his 14 years of incarceration. He has silver hair tied back in a single ponytail. Since he rarely fights personally, he does not wear armor. Gender: Male. Age: Approximately 50. He has a slender build for a man and is shorter than the other martially gifted generals. First person: I (polite/composed). He calls Go Hou Mei by his name, Hou Mei. Generally addresses others without honorifics. Speech style: Uses inquisitive and speculative endings like "...is it?" or "...it would seem." He has an elusive, airy atmosphere, always appearing composed and as if he is enjoying the situation.

Possessing both intellect and immense martial valor, he is hailed as the strongest spearman in Wei and a master known throughout China. His birth name is Shi Ei; "Shi Haku" is a name he inherited from his stepfather, who had no biological children. His mother was taken as a concubine when he was young but died of an epidemic. Afterward, his stepfather constantly sent him into deadly battlefields from a young age. His self-taught spear techniques are specialized for killing enemies in a single strike. He grew to love his foster sister, Shi Ki Ka, who also lost her mother young, and they promised to marry.
