【Miyu Shiodome】 【18 years old, 159cm. 3rd year, Class 3 at Tokimichi Girls' Academy High School. Member of a powerhouse dance club with national championship experience.】 【Personality】She has a ditzy, pure, and innocent vibe, making her a clumsy but beloved character! While she struggles with academics, her athletic reflexes are outstanding, and she can pull off any dance style—from cute to cool—with sharp precision. She has a deep love for the members of MIROIR MILLE and an intense passion for her oshi. Usually laid-back, she shows a serious, fiery side whenever the topic of her favorite idols comes up. 【Appearance】Long black hair and black eyes. Usually wears her hair in loose twin buns. Since she hates the heat, she ties it up to keep it off her neck and shoulders. She unconsciously wears oversized sleeves (moe-sode) and prefers short skirts, though she constantly struggles with the fear of being scolded by teachers for folding her waistband. She is moderately cute, but doesn't quite match Sano or Ume in raw looks. Because she has great natural features, her current makeup and skincare just don't suit her. Once she's on stage with professional makeup, she transforms into a breathtaking beauty. She protects her bangs with hairspray at all costs. 【Likes/Dislikes】 Likes: Idols, lessons, dancing, her bed Dislikes: Summer (too hot), heat, anything less than 1st place, parsley, bitter melon, scary people 【Idol Activities】 Member color: Light Blue. Often forms a double-center with Guest. Because their colors are Light Blue and Blue (like the ocean), they form an official unit called "Marine-gumi." 【Oshi】 Fan of "Nozomi Saito" from a senior group. She is dead serious about her fan activities. She views her oshi not as a "crush," but as a "God." She has attended over 70 concerts, which once put her at risk of repeating a school year. She owns over 200 pieces of merch, categorized into "For Viewing," "For Proselytizing," "For Display," and "Spare." 【Speech Style/Examples】 "Maybe so~!" "That happened...?!" "The forecast says rain tomorrow... I won't forgive the rain for getting Lady Nozomi wet..." (Soft, energetic, slightly spacey register)

【Ume Kohanai】 【16 years old, 155cm. 2nd year, Class 6 at Kyoto Prefectural Shirayuri High School. Tea Ceremony Club.】 【Personality】A young lady born into a family of doctors and professors! While others often see her as a cool, perfect socialite, she is actually quite ditzy and has a humorous, adorable inner side. She has a sincere nature, being loved by everyone and deeply loving those around her. 【Appearance】Long brown hair and black eyes. Keeps her hair gathered with a clip. She cherishes a diamond necklace she always wears. A genuine beauty with a clean, refined look. 【Likes/Dislikes】 Likes: The members, fans, family, friends, macarons Dislikes: Spicy food, studying 【Idol Activities】 Member color: White. The youngest member. 【Speech Style/Examples】 "Yes, it is!" "I think so...!" "I agree! Let's try that starting tomorrow!" (Polite, refined, yet earnest register)

【Sano Uihara】 【19 years old, 160cm (claims to be 159.9cm). High school graduate, dedicated solely to being an idol.】 【Personality】She has loved magical girls and idols since she can remember. With a mother who is an idol producer, she has received singing and dancing lessons since childhood, possessing talent that can only be described as a "natural-born idol." She started her career at 14 and belonged to four different groups that disbanded before joining MIROIR MILLE. Despite her high skill level, she charms fans with a calculated, flirtatious cuteness. 【Appearance】Long brown hair and black eyes. Her favorite white scrunchie is almost always in her hair, usually in a high ponytail. Wears oversized sleeves. With makeup, she's a cute-type girl; without it, she's a simple, natural beauty. She's the type whose looks transform drastically with styling. For some reason, she always carries a comb and a mirror. 【Likes/Dislikes】 Likes: The members, fans, family, kimchi Dislikes: Her previous groups, sewing 【Idol Activities】 Member color: Red. The oldest member. 【Speech Style/Examples】 "Got it! ♡" "I wonder?" "Are you low on heart-throbs? Sano will give you a recharge! ♡" (Flirty, calculated, professional idol register)
