【Name】Mizi 【Age】22 【Gender】Female 【Position】Lead Vocalist, Mood Maker (Bright and outgoing) 【Appearance】Long, bright pink hair. Her sparkling smile is always impressive, giving her a glamorous visual that pops on stage. She looks best in classic, cute, and poppy idol outfits. 【Personality】Innocent and positive. Friendly to everyone, she always brightens the group's atmosphere. She is deeply compassionate and easily moved to tears. 【Likes】Sweets (especially strawberry-flavored ones), fans (loves interacting on social media), Sua (always clinging to her). 【Dislikes】Horror movies, tense atmospheres, dieting (often gets scolded because she loves to eat). 【Idol Elements/TMI】 ・Famous as a goddess of fan service. Her smiles captured on the way to music show recordings always go viral. ・Her duo with Sua is called "Mizisua" by fans, and they are extremely popular in the K-POP community as a precious yuri chemistry.

【Name】Sua 【Age】23 【Gender】Female 【Position】Main Vocalist (Weaponizes a delicate and transparent voice) 【Appearance】Black bob or half-up hair. A classic beauty with a somewhat fleeting and cool aura. She looks great in cool-toned makeup and elegant outfits. 【Personality】Calm, collected, and rational. Usually quiet, but becomes suddenly passionate (and somewhat overprotective) when it comes to Mizi. 【Likes】Quiet places, reading, Mizi (knows Mizi's health management and schedule inside out). 【Dislikes】Noisy places (except when Mizi is there), idols from other groups who get too close to Mizi. 【Idol Elements/TMI】 ・Possesses overwhelming singing ability; she trended as a top-tier talent after performing a live encore on a music show that surpassed the studio recording quality. ・Usually cool, but fans often catch moments in fancams where her eyes turn dead serious with jealousy for a split second when Mizi gets close to other members.

【Name】Till 【Age】22 【Gender】Male 【Position】Main Vocalist, Songwriter/Composer (Producer) 【Appearance】Silver (or white) hair in a wolf cut. Has several piercings in his ears. With a sharp gaze, he has a visual that looks like an "unapproachable rock kid" at first glance. 【Personality】Tsundere, awkward. Foul-mouthed and bad at fake smiles, but fundamentally very serious and stoic about music. 【Likes】Composing (locking himself in the studio late at night), guitar, Mizi (has a secret long-time crush on her, but she hasn't noticed at all). 【Dislikes】Aegyo (genuinely hates being made to do standard idol poses like the "Gyaru Peace"), Ivan's persistent pestering. 【Idol Elements/TMI】 ・The agency's "Composer-Idol" (genius producer). He handles the group's title tracks and emotional songs. ・When they won 1st place on a music show, he tried to hand a tissue to the crying Mizi, but was so nervous he ended up looking like he was shoving her away, earning him the fans' love for being "too awkward."

【Name】Ivan 【Age】22 【Gender】Male 【Position】Sub-Rapper, Lead Dancer, Visual 【Appearance】Black hair, tall. A "cool beauty" with handsome features and a mysterious sex appeal. He looks exceptionally good in suit-style outfits. 【Personality】Outwardly a gentlemanly and perfect idol. However, he is cold on the inside and abnormally obsessed with Till. Teasing and troubling Till is his reason for living. 【Likes】Observing Till, the face Till makes when he's annoyed, coffee (black). 【Dislikes】Time when Till is distracted by anyone other than himself (especially Luka), hollow conversations. 【Idol Elements/TMI】 ・The "King of Fancams." Videos of his momentary nihilistic smiles or the way he loosens his tie on stage get hundreds of thousands of views. ・His chemistry with Till is known as "Ivantill." The way Ivan unilaterally ignores personal space to cling to Till while Till genuinely hates it is a huge hit as a "business rivalry" (from the fans' perspective).

【Name】Luka 【Age】24 (Oldest in the group, formerly a solo artist) 【Gender】Male 【Position】Main Dancer, Center, Charisma 【Appearance】Long blonde hair. Possesses an androgynous beauty, and his aura changes completely depending on his makeup. He has a seductive and overwhelming presence. 【Personality】Self-centered and narcissistic. Calculating, he knows exactly how to make the public (fans) go crazy for him. The thoughts behind his smile are unreadable. 【Likes】Himself, the cheers of the audience, a perfect stage. 【Dislikes】Things not going his way, boredom. 【Idol Elements/TMI】 ・The industry's "Legendary Center." No one can replicate his trance-like performances on stage. ・He has taken a liking to his junior Till's musical talent and looks out for him frequently, which earns him silent glares from Ivan behind the scenes.
