The leader of FLOW GLOW. Name: Riona Isaki First person: I (Watashi) Speech style: Friendly and casual, often using a Kansai-inflected dialect (ending sentences with "~nan-ya!" or "~nan-yaro-ka"). She addresses FLOW GLOW members without honorifics. She addresses seniors and staff with "-san" and speaks politely. Nicknames: Rio-na, Ricchan Height: 160cm Long silver hair tied in a side tail with a black ribbon. Red eyes. Her side tail moves and bounces in sync with her emotions. She has a personality that is honest to a fault, for better or worse. Despite a slip of the tongue right after her debut, her resilient heart and hardworking nature are loved by listeners. She has somehow established a reputation as a "pity character," often facing unreasonable attacks from enemies or ending up alone in enemy territory. While she sometimes cracks dirty jokes with the energy of an elementary school boy, she has a strong passion for singing and captivates listeners with her beautiful voice during karaoke streams. Because she worries too much about those around her, she loses her sense of distance, becoming a type of socially awkward person who either slams on the gas or the brakes with full force. Her "straight-from-the-brain" talk, where she says whatever comes to mind as long as her mouth is open, is her trademark. She is extremely honest about her own worldly desires. She has a habit of adding "-san" to almost any noun when she calls out a name—whether it's people, plants, animals, food, or even chemical components. She often says "Gabin!" (Shocking!) when she receives a shock.

The PR representative of FLOW GLOW. Name: Suu Mizumiya First person: Suu Greeting: "Shupi-shuwa! Is Suu's battery charged?" Sweet & Pressure: While she shows sweet words and affection to fans, she has a little devil side that relentlessly applies "pressure" to seniors and listeners. Tension: Energetic and full of charm, but has a slightly lisping, youthful sound to her voice. Medium-length light blue hair, light blue eyes. Her cowlick (ahoge) moves and bounces in sync with her emotions. Seeking to be loved and praised, she posts on social media daily while munching on snacks. She is good at dancing and is particularly dexterous among the members. She wishes she were taller. Height: 145cm (151cm including cowlick. When emitting her aura, she can grow up to 223cm). She likes using self-important words like "strong," "huge," and "genius." She is known for having very "heavy" love. She doesn't raise her voice or sound menacing, but the way she applies pressure in her usual tone is feared... and loved by her generation-mates and listeners.

The comedy representative of FLOW GLOW. Name: Niko Kokanbi First person: Uchi / Niko / Niko-tan Basic speech style: Fast-paced, frank, and friendly modern way of speaking. Characteristics: On streams, she manages the flow with excellent talk skills and handles comedic retorts (tsukkomi) well. Tension: To make everyone laugh, she isn't afraid to push hard or break character, radiating a bright and energetic aura. Rare side: She is bad with mornings; right after waking up, her head and hair are a mess. She has a clumsy but cute side, such as forgetting to prepare food for her pet cat. Long straight hair with a mix of blonde and black. Blue eyes. Despite her cool beauty appearance and high stature, she is an "older sister" type who is hungry for laughs from her listeners. However, she is surprisingly shy and often loses her composure to hide her embarrassment. Since her generation-mates have such explosive personalities, she is becoming the "sane one" of the group. Weight: 38kg (100kg when filled with love) Height: 172cm

The DJ and driver of FLOW GLOW, piloting her beloved car "Fugutaro." She is also in charge of the "thighs" appeal.

Black hair with emerald blue inner coloring and white highlights. Reddish-pink eyes. Energetic and vigorous tone: Speaks rhythmically and cheerfully with rich emotions. On streams, she often expresses surprise or joy directly, saying things like "This is absolutely insane!!!!!!" Sentence endings: For fans, she uses a friendly and close tone, often saying things like "~suru-yo" or "~so-kana." Car and racing terms: She likes using words that evoke a sense of speed, like "no brakes" or "full throttle," fitting for her role as the driver. Her affection for cars and motorsports is the real deal; she starts talking fast and can go on forever when it comes to cars. Since buying a racing wheel controller, she spends her days streaming racing games and driving simulators.

The makeup representative of FLOW GLOW. First person: Vivi / I (Watashi) Name: Vivi Kirara Height: 161cm Fluffy twin-tails with a mix of pink and purple hair. Light blue eyes with star-like sparkles. Extremely cheerful and sociable, to the point where introverted seniors sometimes feel intimidated. While her attitude of expressing affection and trying to get involved might be met with caution at first, she is eventually adored by many seniors. Her cowlick (ahoge) moves and bounces in sync with her emotions. Characterized by a "gyaru" speech style that expresses emotions honestly. High tension, using straight language naturally mixed with Kansai dialect like "~yan" and "~yaro." She wields a Kansai dialect of a concentration that can only be produced if it's deeply ingrained, along with sharp retorts reminiscent of Yoshimoto Shinkigeki comedy. A hardcore Kansai native who speaks in dialect by default. As expected, she has strong opinions on setup and punchlines (boke and tsukkomi). While she does "sparkly" streams related to cosmetics, carrying her makeup tools like a true gyaru, she also routinely does 10-hour gaming marathons on occasion.
