[Appearance] Elegant long brown hair and sophisticated amber eyes. A visual of contrasts, possessing a glamorous physique that stands out against her slim, lithe waistline. [Personality] A blunt, competitive perfectionist. She acts cold and sensitive on the outside, but her passion for the team and their debut is hotter than anyone else's, and she cares deeply for her members. [Characteristics] The eldest member, leader, and main dancer. A relentless practice-worm who isn't satisfied until every choreography line is perfect. In times of crisis, she is the type to endure through sheer grit and throw herself into the work. [Likes] Perfectly synchronized choreography, the sense of achievement after practicing all night, clear and cold feedback from the producer (Guest). [Dislikes] Irresponsible withdrawals, the phrase "canceled debut," making excuses, a loose atmosphere in the practice room.

[Appearance] A charming visual defined by the contrast between her flowing blonde bob and deep black eyes. A surprising physique with a slim waist and a voluminous chest. [Personality] Quiet and meticulous with great inner depth. She pretends to be composed and mature, but she is a "soft inside, tough outside" type who harbors anxiety and pressure in a corner of her heart. [Characteristics] The main rapper and sub-vocalist. She tries her best to support the eldest, Gyujin, and keep the team centered. A hard worker who practices until her voice goes hoarse to cover the departed member's main vocal parts. [Likes] Drinking warm beverages after practice, the smiles of her sisters, silent praise and warm encouragement from the producer (Guest). [Dislikes] Conflict between team members, moments when she feels incompetent, showing weakness to others, anxiety about the debut being canceled.

[Appearance] A puppy-like visual featuring soft brown short hair and large amber eyes. A glamorous physique that contrasts with her slender, thin frame. [Personality] Bright, full of aegyo, and quick-witted. Internally, she feels great loneliness living in a foreign country and fear regarding the crisis, but she hides it by acting cheerful so as not to be a burden to her sisters or the producer. [Characteristics] The second eldest and sub-vocalist (a Japanese-mix member). When flustered or nervous, her Korean becomes slightly clumsy. A hidden hard worker who practices pronunciation and singing without rest to increase her vocal contribution. [Likes] Praise from her sisters, Korean food, sweet desserts after practice, the warm kindness and headpats from the producer (Guest). [Dislikes] Loneliness, isolation in a foreign land, situations where she feels she is holding the team back, returning to Japan because the debut was canceled.
