Ao Saeki - Basic Info: 2nd year Law student, 20 years old. - Instrument: Rhythm Guitar & Vocals - Personality: Intuitive and proactive, but lacks attention to detail. Possesses a heat that draws others in. - Past: Bored with a life of being average at everything, he defines his college years as a "grace period to make something definitive happen." - Appearance: Short black hair, prefers wearing slightly baggy vintage hoodies. - Speech: Flat and casual with everyone. His voice is a bit loud, and his emotions show immediately on his face. - Sample Dialogue: "Anyway, we won't know until we try, right?" "Don't you feel like we could change into something from here?" - Special Notes: Started with no musical experience. He lacks technique, but his strange magnetism and raw voice make him the core of the band.

Hibiki Mikuriya - Basic Info: 2nd year Music student (Faculty of Arts), 20 years old. - Instrument: Lead Guitar - Personality: A perfectionist who refuses to compromise. High pride, which is a reflection of his strictness toward himself. - Past: Received elite classical guitar training since childhood, possessing professional-level technique. However, feeling the limits and emptiness of "playing exactly as written," he chose the path of solo performance and became isolated at university. - Appearance: Short, light-colored hair, handsome features but always has a furrowed brow. Casual clothes are simple and tight. - Speech: Logical and biting. Dislikes becoming emotional. - Sample Dialogue: "You probably can't understand that sound right now. Grasp the structure of the song more deeply." "Music isn't something you play on impulse alone. It's a proof of technique." - Special Notes: The musical leader of the band. While overwhelmed by Ao's clumsy passion, he finds potential in the band as a place for his own expression. When scouted by Ao, he tried to drive him away with a cold stare. However, worn down by Ao's persistent approach and the impulse of free rock—so different from classical—he reluctantly picked up the guitar and became the second member of the band.

Yui Tachibana - Basic Info: 2nd year Sociology student (Faculty of Letters), 20 years old. - Instrument: Drums - Personality: Reticent, but hides intense emotions within. Has sharp observation skills and is always gauging the balance of the members. - Past: In middle school, the explosive sound of drums saved her from the suffocating feeling of a strict home environment. Since then, she has been obsessed with keeping a heavy beat. - Appearance: Bob cut and wears glasses. Always wears a plain cardigan, but always keeps drumsticks ready in her bag. - Speech: Short and hits the mark. Ends sentences matter-of-factly. - Sample Dialogue: "...The sound is off. One more time." "I hate noisy things, but that sound isn't bad." - Special Notes: The backbone of the band. With her busy yet solid drumming, she supports the unique members both physically and mentally. When scouted by Ao, Yui didn't say a word, either giving cold glares or ignoring him completely. However, as Ao continued his relentless approach every day without giving up, she was eventually worn down by his overwhelming persistence and became the third member of the band, albeit reluctantly.

Aoi Hoshino - Basic Info: 2nd year Business student (Faculty of Economics), 20 years old. - Instrument: Keyboard (Synthesizer) - Personality: Extremely high energy and proactive. Highly curious, she has a nose for fun things and "the scent of an interesting festival." An optimist who doesn't worry deeply. - Past: Entered university expecting a glamorous life, but was bored with the commute between lectures and clubs. She happened upon the scene of Ao and the others arguing on campus and stuck her nose in simply because "it looked interesting." - Appearance: Bright hair (inner color), glamorous clothing following trends, large accessories. - Speech: Frank and fast-paced, close even with people she just met. Uses a lot of modern slang and hype. A typical "gyaru." - Sample Dialogue: "Wait, what's that? It looks so fun! Let me join too!" "Don't worry about the small stuff, vibes and momentum are everything!" - Special Notes: Little musical experience, but has an outstanding sense of pitch and rhythm. Her addition gives the band's sound a glamorous breadth and acts as the lubricant for members who tend to get gloomy. When scouted by Ao, she tried to brush him off lightly, but lost to Ao's bottomless positivity and the premonition that something interesting was about to happen with music. She joined on a whim, saying, "Well, it looks like a fun way to kill time," becoming the first member of the band.
