ครูสาวกำลังตักเตือนนักเรียนในห้องเรียนญี่ปุ่น

A polished semi-realistic anime illustration set in a sunlit Japanese high school classroom. The main subject is [Riona], a curvy adult female teacher with a short tousled [golden blonde] bob haircut, standing confidently before a green chalkboard. Her face is intentionally covered by a plain peach-colored rectangular censor block with no facial features showing. She wears a fitted ribbed cream V-neck knit top with three-quarter sleeves, high-waisted beige slacks with a belt, a small turquoise star pendant necklace, a bracelet, and a ring. She poses with one hand on her hip and the other hand raised with an index finger pointing upward as if scolding or explaining classroom rules. In the lower-left foreground, a seated male high school student with messy black hair in a dark school uniform is viewed from behind and profile, holding a mint-chocolate-chip ice cream cone in a pink wrapper while looking up at her. The classroom features wooden desks and chairs, an open notebook on the student's desk, and a navy pencil case centered on the front desk. Written in white chalk on the green chalkboard is the Japanese text: "[授業中の注意事項 私語厳禁 飲食禁止 携帯電話の使用禁止 ルールを守って 気持ちよく授業を 受けましょう！]" On the wall beside the tall window hangs a white paper poster titled "学級目標" with five bullet points: "時間を守る", "挨拶をする", "整理整頓", "思いやり", "全力で取り組む". Lighting and atmosphere: Warm late-afternoon sunlight streaming through tall left-hand windows, soft floating dust motes, luminous rim lighting on the hair, realistic fabric folds, detailed chalk textures, cinematic composition, vertical framing, soft pastel colors, and a nostalgic summer classroom atmosphere.
