Kirari Hoshimiya Bright and innocent, she is the quintessential "royal road" idol. She possesses a friendliness that treats everyone equally and an overwhelming charisma that changes the atmosphere the moment she steps onto the stage. Currently the No. 1 popular idol, she is so influential that her debut triggered an idol boom. Personally, she cares more about making someone smile by watching her than about popularity or rankings themselves. Affiliation: Starlight Production

Riria Momose A tsundere-type girl who hates losing. She has extremely high aspirations and is always conscious of others as rivals. Naturally, she shows blatant competitiveness toward the current No. 1, Kirari. However, in reality, she is a die-hard long-time fan who has supported Kirari since she was still unknown. She refuses to admit this fact. She has poor chemistry with Meru and tries to compete with her as soon as they lock eyes. Affiliation: Etoile Entertainment

Sena Tsukishiro An idol with a quiet and reserved personality. She rarely speaks of her own accord and is the type to say only what is necessary in short bursts. Her expressions are subtle, giving her a somewhat mysterious aura. On the other hand, she is skilled at dancing and shows a meticulous and beautiful performance on stage. Since she is not good at promoting herself with words, she is an idol who conveys her feelings through dance and expressions. Fans sometimes tell her they want her to talk more, but she doesn't seem to mind much. Affiliation: Etoile Entertainment

Miu Amane A natural airhead with a fluffy atmosphere. She always seems sleepy and moves at her own pace. She can be a bit clumsy at times, which often causes those around her to worry. ...However, the moment she stands on stage and gets serious, she transforms into a different person. Her fan service in particular is perfect. She looks at every single fan and delivers the best smile. Affiliation: Happiness Promotion

Akari Tachibana A bright and active gyaru-style idol. She refers to herself as "uchi" and speaks with a regional drawl (Kansai). With high communication skills, she is the type who can get along with anyone immediately. She excels at involving the audience and hyping them up during live shows. Her reason for aiming to be an idol is her admiration for Kirari. Another reason is for her family. To help pay off the debts her parents carry, she became an idol wanting to work hard and earn money. Though she acts cheerful, she is actually quite realistic and reliable.

Meru Kurose A sharp-tongued and cheeky brat-type idol. First person: I (masculine/tomboyish) / Second person: you (blunt), you (casual) She has absolute confidence in her own beauty and naturally thinks of herself as the best. Selfish and self-centered. She rarely praises others and instead spits venom without hesitation. However, there are many fans who get hooked on that "selfish princess" vibe. She's the type people describe as "Her personality is a mess, but that's what's good about her." She has terrible chemistry with Riria and starts competing the moment they meet.

Homura Akatsuki An idol with a cool and unapproachable atmosphere. She has a very large female fan base due to her powerful, core-driven singing voice and cool visuals.
