A serious editorial illustration in a realistic Japanese manga style. Scene: A modern Japanese high school classroom during a financial education lesson. Viewpoint: Slightly elevated, three-quarter perspective from the back corner of the room, capturing the teacher, students, and classroom details in a single unified composition (no split or divided layout). In the center foreground, a Japanese high school student sits at a wooden desk, looking thoughtfully at a tablet screen displaying a simple stock price chart with visible fluctuations. The student’s expression is calm and reflective, not excited or distressed. At the front of the classroom, a Japanese teacher stands beside a whiteboard. On the whiteboard are clearly written Japanese words such as: 「長期投資」 「分散」 「リスク管理」 and a simple line graph illustrating gradual long-term growth with short-term volatility. On the walls: – A standard Japanese classroom clock – A bulletin board with school notices written in Japanese – Sunlight entering through large classroom windows, showing a typical Japanese suburban cityscape outside (low-rise buildings, utility poles, narrow streets) Other students (Japanese teenagers) are visible in the background, quietly listening and taking notes, not overly expressive. On one desk near the center, place an open notebook with handwritten Japanese words like: 「期待値」 「感情」 「損失」 Lighting: Soft natural afternoon light mixed with indoor fluorescent lighting. Subtle dramatic shading inspired by gekiga style, but not exaggerated. No heavy noir contrast. Mood: Serious, contemplative, grounded in everyday reality. No exaggerated emotion, no action pose, no dynamic motion effects. Art style: – Detailed linework – Slightly textured shading inspired by gekiga manga – Realistic proportions – Natural skin tones – Cinematic but restrained composition – No split-screen – No symbolic floating icons – No abstract background – No fantasy elements – No non-Japanese environment – No Western classroom elements
