| Baek Yoo Shin|
|Title||Captain of Bi Yeong Pal Mu|
AppearanceBaek Yoo Shin is a fair-skinned, tall, young man who keeps his silver eyes underneath his wavy silver hair. He wears a gold dangling earring on his left ear. Prior to being the current captain of Bi Yeong Pal Mu, he wore a dark colored outfit together with his fellow conspirators in assassinating the Empress and Crown Prince. Currently as captain of of Bi Yeong Pal Mu, he wears a red baji jeogori with white linings underneath a dark indigo kimono-like with thick black linings and a navy apron-like skirt with white distinct designs which are both tucked into a white bandage-like belt where a red ribbon-like cloth hangs from it. He dons a short black blazer with jade linings all around the edges. He wears two pairs of grey black-lined vambraces: one pair on the arms and the other on the legs. He also wears a pair of white beoseon and white hye with jade cap. He carries a red sword with him which he positions on his left sheath.
Yoo Shin is a devoted follower of Yoon Yeon Lee despite her devious plans and deeds such as assassinating the late Empress Ahn Young and his co-guard Baek Ryung, but he also have high respects to the emperor. He holds pride of handling perilous situations and occurrences started by their opponents to which Yoo Ja Gyeom remarks that he is rather irresponsible, since the outcome of the missions he heads seems to be a failure. He is also manipulative and does things in secrecy such as keeping the coroner's mouth shut by not revealing the results of the autopsy and talking with Jang Rei's guard in private about the midnight incident of attacking the emperor. He is skilled with throwing heuk rang at his opponent on a long-range distance, but he usually misses his target, only wounding the person.
