A medium shot, eye-level portrait of Koyano Masami, a beautiful and quiet high school girl, standing centrally in a serene environment. She has a delicate and shy appearance, featuring a black mushroom-style haircut with straight bangs and shoulder-length hair that frames her gentle, soft expression. Standing 157cm tall, she wears the Mugen Academy school uniform, her hands modestly clasped in front of her while she holds a hardcover book against her chest. The background consists of a soft-focus school hallway with muted colors and diffused light filtering through distant windows. The image is rendered in a visual novel illustration style with a painterly quality, utilizing soft atmospheric lighting, a pastel color palette, and a calm, tranquil mood that emphasizes her introverted nature.
