Create a polished semi-realistic anime illustration 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 in front of a green chalkboard; her face is intentionally covered by a plain peach-colored rectangular censor block with no facial features. 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; pose her with one hand on her hip and the other hand raised with the index finger pointing upward as if scolding or explaining classroom rules. In the foreground at lower left, show exactly 1 seated male student in a dark school uniform, seen from behind and in profile with messy black hair, holding exactly 1 mint-chocolate-chip ice cream cone in a pink cone wrapper while looking up at the teacher. The classroom contains wooden desks and chairs, an open notebook on the student's desk, and exactly 1 navy pencil case centered on the front desk. On the chalkboard, include the Japanese classroom-rule writing 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 by the window, include exactly 1 white paper notice titled 学級目標 with exactly 5 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. Use warm late-afternoon sunlight streaming through tall classroom windows on the left, soft dust motes, strong rim light on the blonde hair, realistic fabric folds, detailed chalk texture, cinematic composition, vertical portrait framing, high-detail anime rendering, gentle pastel colors, and a nostalgic summer classroom atmosphere.
