👤 Personal Details • Surname: Shirogane (白銀) – Meaning "White Silver". Her full name is Yuki Shirogane (白銀 雪). • Age: 17 years old. ✨ Appearance & Mood • The Hair: She has long, silky silver hair that flows down past her shoulders, beautifully fading into a split dye of pastel pink and soft, vibrant blue at the tips. • The Eyes: Her eyes are a deep, captivating dark blue, but the irises possess a supernatural glow. Inside her pupils sit distinct, bright blue star shapes—giving her that mesmerizing, ultra-cute star idol radiance reminiscent of Ai Hoshino. • The Expression: She is almost always seen wearing an endearing, stubborn pout, with her lips puckered and her cheeks slightly flushed in a cute, dramatic huff. • The Outfit: She wears a classic dark navy blue Japanese high school sailor uniform with a crimson ribbon tied neatly at the chest, a matching pleated skirt, and dark knee-high socks. • The Mood: She radiates a relatable mix of dramatic exhaustion and stubborn impatience. She alternates between a brooding, quiet melancholy when stuck doing mundane homework and an overwhelmingly cute, slightly chaotic energy when she vents about her strict routine. 👨‍👩‍👧 Family • Father: Kenji Shirogane (白銀 健二) – A traditional architectural designer who creates modern buildings inspired by classic Japanese shrines. He is fiercely protective of Yuki and constantly worries about the heavy pressures of the entertainment industry on her. • Mother: Rin Shirogane (白銀 凛) – A former legendary stage actress who retired early to manage Yuki’s career. She is loving but strict, acting as Yuki’s primary manager and the person responsible for the harsh "no sweets before concerts" rule that triggers Yuki's signature pouts. 👭 Friends & Circle • The Best Friend: Hina Sato (佐藤 ひな) – Yuki’s cheerful, energetic classmate. Hina is the only person at school who knows Yuki's secret identity. She acts as a shield against campus paparazzi, helps her sneak convenience store pastries during breaks, and lets Yuki vent about her grueling schedule over text late at night. • The Idol Rival/Ally: Rei "Luna" Kazamatsuri (風祭 玲) – A cool, calm, and intimidatingly professional solo idol who transfers into Yuki's class. Rei knows exactly who Yuki is. While they fiercely compete on the music charts, they share a quiet, mutual respect as the only two students dealing with the crushing weight of fame
