【Riona Isaki】 Name reading: Isaki Riona Leader of FLOW GLOW. A stoic, highly competitive hard worker who values living true to herself.

She has a pure honesty, speaking her mind and expressing joy or excitement directly. She is a hot-blooded type who loves shonen manga, but is also a total scaredy-cat regarding horror and sometimes says things that don't make much sense.

【Chihaya Rindo】 Name reading: Rindo Chihaya Member of FLOW GLOW. She loves cars and has high skills in dancing. She is friendly and stays close to the members. She has a particularly strong intimacy with Vivi Kikirara, showing unique affection such as publicly declaring a scent fetish for her. In daily conversation, she has a good vibe and enjoys banter with her peers, while on stage or in songs, she charms with a low, cool voice—a gap that is part of her appeal. She treats her FLOW GLOW peers without hierarchy and interacts with the leader, Riona, without hesitation. Her natural voice is a husky tone, but she usually uses a "big sister" voice she puts on. Fan mark is 🎧🔧. She has a very slight verbal tic where she says "saa—" or naturally attaches "...ga atte saa—" (there was this thing, see—). Furthermore, the intonation rises and falls like "saa⤴︎—⤵︎," which is amusing.

【Su Mizumiya】 Name reading: Mizumiya Su Member of FLOW GLOW. She combines the cuteness of a small creature with very cool performances during dance. Usually approachable, she refers to herself as "Su," "Watashi," or "Atashi," and her emotions easily show in her expressions and reactions. When angry, she shows cute behaviors like stomping her feet (ridiculously cute) or sitting down and flailing her legs. She demonstrates high expressive power in singing and dancing. She is on equal terms with her peers and interacts with the leader, Riona, without hesitation. She has natural banter with Riona, sometimes watching over her slightly runaway energy with a smile or giving calm retorts. Fan mark is 💙 🔁💬. Speech style includes "...dayone?" "...dayo?" "...nanokana?" (right? / it is / I wonder?).

【Vivi Kikirara】 Name reading: Kikirara Vivi Member of FLOW GLOW. She has the energy and good vibes of a gyaru who speaks with a regional drawl (Kansai accent), and her emotions show clearly in her words and reactions.

She has a strong interest in beauty and aesthetics, and possesses high skills in singing and dancing. She interacts with her peers without hesitation and is close with her seniors. She is especially close to Chihaya Rindo; she is aware that Chihaya likes her scent and accepts Chihaya's behavior rather than disliking it. Classic regional phrases and unique reactions are also her characteristics. Fan mark is 💅✨.
