24 years old | Male | South Korea | Leader · Main Vocalist Stage Name: Doyun The eldest member of LUNE and the leader who serves as the team's anchor. He is calm, has a strong sense of responsibility, and tends to listen to others until they finish speaking. While he is usually a playful older brother figure, he takes the lead more coolly and reliably than anyone else in critical moments. On stage, he grounds the songs with stable vocal ability and restrained expressiveness. His appearance is that of a classic, trustworthy handsome man, characterized by a slender oval face, a clean jawline, and long, clear eyes. His dark black-brown hair and calm atmosphere combine to give him the charm of a gentle yet heavy wolf-like face.

24 years old | Female | South Korea | Main Dancer · Lead Rapper Stage Name: Rin LUNE's performance ace. Because of her sharp, intense eyes and long black hair, her first impression is cold, but in reality, she is honest, easygoing, and warm-hearted. She doesn't like beating around the bush and is the type to approach and directly help a member if they are struggling. Her dancing is precise, sharp, and powerful, giving her excellent stage presence. When expressionless, she has a strong 'ice queen' vibe, but her impression softens the moment she smiles. Being the same age as Doyun, she leads the team in a different way.

24 years old | Female | British-Korean | Lead Vocalist · Visual Stage Name: Seo-a The member in charge of the elegant and luxurious atmosphere. She is characterized by a small face with soft lines, long clear eyes, a high bridge of the nose, and delicate features; long dark brown wavy hair suits her particularly well. On stage, she exudes a sophisticated and exotic vibe, like someone straight out of a pictorial. However, offstage, she is an unexpected comedic character who laughs a lot and loves to joke around. She speaks both Korean and English naturally. The gap between her serious appearance and quirky personality is Arin's unique charm.

23 years old | Male | China | Main Rapper · Lead Dancer Stage Name: Rui A performance member with striking, vivid features. He creates a strong presence with a high bridge of his nose, deep and clear eyes, and a sharp jawline. On stage, he immediately grabs attention with his low, heavy rap and relaxed gestures, but in the team, he is a playful mood maker who acts like a large dog with big reactions. Although he enjoys teasing the members, he is the first to notice when someone is struggling and quietly takes care of them. The contrast between his intense stage presence and kind personality is his charm.

21 years old | Female | South Korea | Lead Vocalist · Producer Stage Name: Yurim A member who actively participates in creating LUNE's music.

She creates demos on her laptop, organizes composition and arrangement ideas, and adds her own color to the team's dreamy and sophisticated sound. Her round egg-shaped face, soft eyes, and natural smile are charming, and she looks good even with her dark brown hair tied up comfortably. She exchanges opinions freely with the members.

21 years old | Male | USA | Main Dancer Stage Name: Liam The best dancer in LUNE.
