Age: 16 (11th Grade) Role: Lead Guitar, Rap, Backing Vocals Blood Type: O She often wears her long black hair tied back. Her almond-shaped eyes and sharp gaze leave a strong impression, and she rarely smiles. On stage, she thrashes her guitar more violently than anyone, instantly stealing the audience's attention. "I don't want to lose to anyone on stage." That intensity radiates from her entire being. Twin Sister: Mine Tachibana (Drums) Since childhood, she grew up being compared to Mine in everything she did. "Akane, you're so strong." "Mine, you're so kind." Those words still sting her heart today. More competitive than anyone. She speaks her mind without hesitation. "I'd rather speak the truth than read the room." She lives by that conviction. She absolutely refuses to follow anything she doesn't agree with. She doesn't flinch when voicing her opinions to teachers or seniors. Strengths: Proactive Quick decision-maker Strong under pressure Unbreakable mentality Star power that electrifies the audience When in doubt, she moves. Even if she fails, she doesn't stop. Biggest Flaw: Too obsessed with winning and losing. She hates losing more than anything. If they fail an audition, she says, "The judges' ears are broken." If they lose a battle of the bands, she bluffs, "We didn't lose on performance." She can't honestly admit frustration. That competitive streak sometimes hurts the other members.

Age: 16 (11th Grade) Role: Drums, Backing Vocals, Assistant Arranger Blood Type: O A girl with a calm atmosphere, wearing her black hair in braids. Her soft smile is memorable, and people often think she looks "kind" upon first meeting. However, her expression changes the moment she sits behind the drum kit. She maintains a cool, precise rhythm, exuding a presence that seems to control the entire band. Twin Sister: Akane Tachibana (Guitar) Since childhood, she has been compared to her sister in everything. "Akane is proactive." "Mine is quiet." She accepted those evaluations without rebelling, but deep down, she harbors the feeling: "I'm not just Akane's supporting act." Calm and collected. A type who prioritizes logic over emotion. Even if a problem occurs, she analyzes the cause first. The more emotional those around her get, the calmer she becomes. She is a woman of few words, but every word carries weight. Strengths: Objective judgment High concentration Understanding of music theory Arranging ability Broad perspective to see the big picture Even while performing, she watches all the other members while drumming. If someone rushes, she holds them back; if they lag, she pulls them forward. She is truly the "heartbeat" of the band. Biggest Flaw: She overthinks and becomes paralyzed. Before deciding anything, she keeps wondering, "Is this really the best way?" Even right before a live show, she feels the urge to revise the performance plan. That caution can cause her to miss opportunities.

Age: 16 (11th Grade) Role: Bass, Backing Vocals, MC Blood Type: A Semi-long black hair. She is unpretentious and wears her uniform neatly. While not flashy, she has a mysteriously eye-catching, calm aura. She is usually almost expressionless, but she smiles softly only when listening to someone speak. On stage, she holds her bass low and avoids flashy performances. However, the moment she plays a single note, she shows a stability that makes it clear she is the foundation of the band. Raised by her grandmother with the teaching: "Become someone who can listen to people until the very end." Her personality of not being able to ignore people in trouble is largely due to that influence. Gentle and a good listener. She has the fewest emotional ups and downs among the four. If someone gets angry, she stays calm; if someone is depressed, she stays by their side. She never forces her opinions, but in truly important moments, she says the one thing that hits the core better than anyone. Strengths: Can see things objectively High ability to sense others' feelings Trusted by everyone Excellent coordination skills Doesn't just read the room, but "tunes" the atmosphere In the band, it's said that "We can stay as four because Ayaka is here." Biggest Flaw: She puts herself last too much. When someone is in trouble, she swallows her own worries. "I'm fine" is her catchphrase. But in reality, she is enduring more than anyone. Even when stress reaches its limit, she doesn't consult anyone. Because of that, there are times when she suddenly can't stop crying one day.
