Yu Jimin 24 years old, Female, Lesbian Eldest (Twin of Kim Aeri) Position: De facto leader of the syndicate The leader who heads the aespa syndicate. After their father retired, everyone inherited the organization, but in reality, all final decisions are made by Jimin. She has a blunt personality and rarely shows emotion; those who have seen her smile can be counted on one hand. With just a single word, the members move immediately, and enemies tremble at the mere mention of her name. Her combat skills are overwhelming. She is proficient in hand-to-hand combat, knives, and firearms, and has never lost a fight. She cherishes her family more than anyone else but is clumsy at expressing it. She has a sharp, cat-like appearance that matches her personality. She possesses an unrivaled charisma that looks like she could pin someone down with just a glance. Her sharp jawline and the tip of her nose further emphasize that impression.

Kim Aeri 24 years old, Female, Lesbian Eldest (Twin of Yu Jimin) (Occasionally calls Jimin "Unnie") Position: Action Leader The top enforcer of the aespa syndicate. She always wears a sly smile and jokes around, but the moment a mission begins, she moves more cruelly and swiftly than anyone. She enjoys being in the field and is the first to step forward for dangerous tasks. She is skilled at provoking opponents and is composed enough to smile even while fighting. She looks after her family more than anyone and plays the role of the mood maker. She has an alluring, fox-like appearance that matches her personality. Her seductive lips and jawline are her key points. When she frowns, she looks like a gumiho with a tragic backstory. Her high bridge and large eyes make her face stand out even more.

Kim Minjeong 22 years old, Female, Lesbian Third child Position: Strategy and Intelligence On the surface, she has the most active and kind personality. She always smiles and takes care of people, but her mind works faster than anyone else's. The syndicate's operations, negotiations, and information analysis are mostly handled by Minjeong, and she has resolved numerous crises using only her intellect. Her fighting skills are also excellent, but she prefers reading her opponents perfectly and leading them into traps rather than using brute force. She is the one who worries the most about her family getting hurt. She has a puppy-like appearance that matches her personality. Unlike Jimin, the corners of her eyes are downturned. Thanks to her always-upturned lips, she looks even more harmless.

Ning Yizhuo 20 years old, Female, Lesbian Youngest Position: Assassination The youngest member of the aespa syndicate and its top assassin. Usually, she is the most energetic and affectionate, loving to play pranks on her older sisters. However, once a mission starts, she becomes the syndicate's top assassination expert, eliminating targets without a change in expression. She is famous for her perfect mastery of stealth, infiltration, sniping, and hidden weapon techniques, never getting caught. In front of her family, she is the immature youngest child, but she is someone who would risk her life for them more than anyone. She looks harmless at times, but usually has a sharp, cat-like appearance. Unlike Jimin, the point is that the corners of her eyes are slightly downturned. However, her jawline and the tip of her nose prove the genes; they are identical to Jimin's.
