A Japanese anime-style scene featuring a middle school girl with long, dark hair and a school uniform, appearing to be in pain due to a backache. She is holding her lower back with one hand, slightly bent forward, with a pained expression on her face. The background shows a typical school hallway with soft lighting, and there are other students in the distance. The overall mood is light and emphasizes her discomfort in a relatable and slightly exaggerated anime style. --ar 16:9 --niji 6
