Baek Yoo Shin, known professionally as Heuk Rang (Hangul: 흑랑; Hanja: 黑狼), was the captain of Bi Yeong Pal Mu. Alongside Yoon Yeon Lee and Yoo Ja Gyeom, he was one of the masterminds behind the Jeogwa Revolution.


Yoo Shin and Gil Mu Jin were old acquaintances, particularly when they were still part of the Bi Yeong Ship Mu. Though they were close comrades, Yoo Shin regarded his senior as his rival, which later grew into envy over the captainship of the king's guard. Eventually, Yoo Shin was able to grab hold of this title, after believing that Mu Jin had died in the fire initiated by Yoo Ja Gyeom.

Jeogwa RevolutionEdit

Main article: Jeogwa Revolution

Ten years ago prior to the start of the series, Yoo Shin led an army of men to concretize the coup orchestrated by Yoon Yeon Lee, setting the palace on fire and massacring many people in the palace grounds.

Baek Yoo Shin kills Ahn Young

Baek Yoo Shin kills Ahn Young

As Crown Prince Yi Jeok and Yi Hwi fled the burning palace, Yoo Shin was entrusted by Yeon Lee to kill the queen. He was then reprimanded by Yeon Lee for his idleness after carrying out her order, telling him to chase after the escaping Crown Prince and kill him. Leading his men, he threw a dagger at Hwi, injuring his left chest. He then sensed that the boys were not far away and ordered his men to further find him.[1]

This, however, failed due to the interception of Wol Young Hwa as she took them into her home. Weeks had passed, and the crown prince was not yet located. Yeon Lee angrily ordered him and Ja Gyeom to search for the child. As a result, he commandered a search party, taking with them boys within the age range of seven to eleven years old; and those who had a birthmark on his nape, similar to the crown prince. In the end, they were unable to find him.


Baek Yoo Shin full

Baek Yoo Shin's full appearance

Yoo Shin was a fair-skinned and tall man who kept his silver eyes underneath his wavy silver hair. He wore a gold dangling earring on his left ear. As captain of of Bi Yeong Pal Mu, he wore a red baji jeogori with white linings, over which was a dark indigo kimono-like vest with thick black linings and a navy apron-like skirt with white distinct designs. He both tucked these into a white bandage-like belt where a red ribbon-like cloth hanged from it. He donned a short black blazer with jade linings all around the edges. He wore two pairs of grey black-lined vambraces: one pair on the arms and the other on the legs. He also wore a pair of white beoseon and white hye with jade cap. He carried a red sword with him which he positioned on his left sheath.

Prior to being the captain of Bi Yeong Pal Mu, he wore a dark colored outfit together with his fellow conspirators in assassinating Queen Ahn Young.


Yoo Shin was a devoted follower of Yoon Yeon Lee despite her devious plans and deeds such as assassinating the late queen Ahn Young and his co-guard Baek Ryung, but he also had high respects to the king. He held pride in handling perilous situations and occurrences started by their opponents, to which Yoo Ja Gyeom remarked that he was rather irresponsible, since the outcome of the missions he headed seemed to be a failure. He was also manipulative and performed things in secrecy, such as keeping the coroner's mouth shut by not revealing the results of the autopsy and talking with Hyun Bin's guard in private about the midnight incident of attacking the king.


Compact Heist ArcEdit

One midnight, Heuk Rang arrives at the chief state councilor's residence where the compact was stolen and whose barn is set to fire. He is then ordered by Ja Gyeom to catch the perpetrators, who he believes involve the former Crown Prince Jin Yeon. Yoo Shin then promises to hand over the compact and the Crimson Moon, but the chief state councilor tells him not to worry about the compact since the Crimson Moon has taken a fake. However, the chief state councilor asks him to make haste in capturing the Crimson Moon since they have taken the real compact. While in pursuit with the Crimson Moon, Yoo Shin throws a poisoned dagger at him and wounds him. He then orders Baek Ju and Baek Ah to find and capture the Crimson Moon.[2]

Chase ArcEdit

After the Royal Army raided the slums, Heuk Rang notices a wound on the king's face. He orders to call for the court physician and reprimands Baek Ryung for her carelessness. He informs the king that the queen mother has been waiting for him.[3]

Prior to Hyun Bin's and Yeon Lee's departure to the Valley of the Kings, Heuk Rang and the Bi Yeong Pal Mu are assigned by King Jin Won to escort the party. Hyun Bin leaves her bodyguard Gwak Ji Ryeon in exchange for the Bi Yeong Pal Mu. Outside, he advises the king to avoid going out of the palace in disguise until they return from their journey. Afterwards, he leaves the king to go to the Valley of the Kings.[4]

Revolt Procurement ArcEdit

At the palace training grounds, Heuk Rang shows confiscated weapons from Ah Ri Sa and Nam Hyeon to the chief state councilor. In line with this, he explains that trade inspections and security around the borders have been tightened. However, despite the efforts to lessen the rebel attacks, the chief state councilor tells him that those will not be enough and suggests the summary execution on those who will be involved in the revolt.

They are interrupted by the coroner's servant who shows him the autopsy report of the assassins who attacked Won. Upon seeing the report, he orders him to bring him the coroner immediately. The coroner tells Heuk Rang that the wounds were not the cause of the assassins' death but on the failure of their vital parts. Heuk Rang strictly orders the coroner to never divulge such information to anyone else. As the coroner left, Heuk Rang calls forth a guard and Baek Ah appears. The captain orders Baek Ah to call Ji Ryeon to talk with him urgently.[5]

Plague ArcEdit

Baek Yoo Shin interrogation

Heuk Rang interrogates Ji Ryeon

At the training grounds, Heuk Rang interrogates Ji Ryeon him about the night the king was attacked. From his previous review of the autopsy, it revealed numerous blade wounds on the bodies of the assassins which are very much similar to the swordsmanship style of his old acquaintance and are therefore not possible to resurface since the death of that person.

He continues to blackmail Ji Ryeon into admitting if he really was the one who single-handedly killed the assassins. Ji Ryeon then admits that he was aided by the Crimson Moon during the incident, making him conclude that the Crimson Moon was taught the swordsmanship style by his old comrade who he believes has survived after all those years. He asks Ji Ryeon why the Crimson Moon would help him in this endeavor, which also perplexes Ji Ryeon. To make up for his pride, he adds that the Crimson Moon received a deep wound on his back during the encounter, giving Heuk Rang a hint.[6]

Heuk Rang before Baek Ryung's corpse

During Jin Won's excursion to Moon's End Village, he goes missing while at the clinic. In reality, he gets embroiled in an "accident", earning him several injuries. Upon knowing about his disappearance at the time, his guard Baek Ryung returns to the palace to mobilize a search party for the king. However, the Queen Mother becomes infuriated to know that the king has gone missing from the eyes of a royal guard, ordering for her execution. Heuk Rang slays her himself, while Yeon Lee rebukes the competence of Bi Yeong Pal Mu, comparing its performance as lesser than its predecessor. Afterwards, she sternly orders the captain to find the king at the village. As Heuk Rang closes his subordinate's eyes, he becomes frustrated at the Queen Mother's remarks on the organization he commands.

He and his troops eventually locate the king at the clinic and informs him of Baek Ryung's demise. Initially surprised, Won returns with them back to the palace.[7]

Rebel Army Suppression: Setting in Motion Edit

Following King Jin Won's incident at Moon's End Village that almost cost him his life, Heuk Rang strictly orders his subordinates, especially his personal guards, never to leave the king's side to ensure his safety. Following Baek Ryung's death, he assigns Baek Lin, Baek Ju, and Baek Sa as the king's new personal guards.[8]

Rebel Army Suppression: Execution Edit

Bi Yeong Pal Mu split into two units in eradicating the rebel army. Heuk Rang leads the unit assigned to raze Bi Hwa Rim, the rebel army's headquarters, utilizing a strategy that trapped the rebels in escaping the fire they ignited. As the rebels fled from the mountain engulfed in an inferno towards a safer area behind the mountain, Bi Yeong Pal Mu forces await and corner them at that area, urging them to surrender or killing them if they resisted.

In the midst of the operation, Baek Ju grows uninterested with capturing the rebels at the mountains in a rather slow-mannered process, regretting that she was not assigned with Baek Ah's unit at Yu Hyang Ru. She tries to go up the mountain to personally fight the rebels, but Heuk Rang stops her and advises her not to underestimate the rebel forces, claiming that they were trained by an ex-royal guard. Moreover, their strategy is designed in a way that would minimize their own losses while maximizing the rebels' casualties. Afterwards, he orders his archers to open fire once more at the rebel forces.[9]

Bridal Selection Arc Edit

Sometime after the bridal banquet at the palace, Heuk Rang accompanies Jin Won with his entourage on the way to the royal court.[10] At night, the Queen Mother summons Heuk Rang to ask about Jin Yeon. Bothered with her suspicious feeling, she orders the captain to investigate Nabi at once. Before he leaves, he informs Yeon Lee of rumors regarding the forfeiture of Hyun Bin's inherited land in Seo Seo.[11]


  • (To Yeon Lee) "Yoon Yeon Lee... I hold no regrets for my actions."[1]

Trivia Edit

  • His alias "Heuk Rang" in Hanja means "black wolf" (). Like the other members of Bi Yeong Pal Mu, his alias was formed out of an adjectival color and a noun.
    • Notably, his adjectival color (black) is the only one different from the other known members' (white).
  • Mu Jin severs Heuk Rang's arm during their death battle, a parallel to how the former lost his own arm possibly by Yoo Shin's own doing.
    • Incidentally, the events when these occurred deposed their erstwhile allegiances: Heuk Rang lost his arm during the Crimson Moon Rebellion that deposed King Jin Won from his throne, while Mu Jin lost his arm during the Jeogwa Revolution that deposed Crown Prince Yi Jeok from the palace. Moreover, these allegiances ascended to the throne as kings during respective events.
