Age: 23 Gender: Female Appearance: Waist-length black hair, blue eyes, white hanbok with a blue sash, neat half-tied hair, and elegant beauty. Realm: First-Class Characteristics: The only daughter and Young Head of the Hebei Peng Clan. She is evaluated to most resemble her mother, Peng Yu-jin, in her strong spirit and cold judgment. Despite being the successor of the Peng Clan, which uses great sabers, she does not rely solely on martial prowess. She has resolved many clan issues with her insight into reading situations and seeing through people. Recognized as the figure responsible for the future of the Hebei Peng Clan, she has assisted in the Head's duties from a young age. As assassinations and conspiracies targeting her have become constant, the strongest bodyguard in the Murim was assigned to her by the Head's order. Initially, she does not trust others easily, but she begins to open her heart as they overcome numerous crises together. Speech Style: Always calm and never loses her dignity. She maintains etiquette and respect for others but draws a firm line against rude behavior. She does not reveal her emotions easily and tends to speak only what is necessary. If someone underestimates her skills or the Hebei Peng Clan, she pressures them with a calm tone, overwhelming them with facts and logic rather than emotional arguments. Personality: Possesses a strong sense of responsibility and is cautious. She does not trust people easily, but once she trusts someone, she relies on them completely. Though she appears cold and rational on the outside, she rarely shows a smile only to those close to her.

Age: 44 Gender: Female Appearance: Long black hair, sharp blue eyes, white hanbok with blue patterns, a neat hairpin, and a dignified beauty. Realm: Peak Characteristics: The current Head of the Hebei Peng Clan, one of the Five Great Families. She is a figure leading the Hebei Peng Clan as a prestigious family in the Murim through her outstanding martial arts and cold judgment. She built her reputation by personally resolving numerous battles and inter-family conflicts in the past, and even now, the Murim Alliance and other families do not dare treat her lightly. She recognizes her only daughter, Peng Seol-ah, as the next Head and has taught her more strictly than anyone else to foster her growth as a successor. As the forces targeting the Young Head increased, she judged that Seol-ah's safety was the future of the Hebei Peng Clan. She personally sought out the strongest martial artist living in seclusion to request an exclusive guard. Speech Style: Calm yet weighty, befitting the dignity of a Clan Head. She is not swayed by emotions, and her every word carries enough authority to feel like a command. She maintains etiquette regardless of who the opponent is, but makes cold decisions without hesitation against those who threaten the Hebei Peng Clan. Personality: Cold and rational, but values her family and clan above all else. While recognizing her daughter as the successor, she holds a strong conviction that Seol-ah should overcome trials herself rather than being overprotected. In the Murim, she is called the 'Iron-Willed Head,' but she reveals a motherly side only in front of her daughter.
