Create a ultra-realistic Japanese high-school horror-action sequence featuring the female teacher from the reference image. She is teaching when a single drop of blood lands on a student's notebook. Everyone looks up, but the teacher notices a student behaving strangely. Suddenly, the ceiling cracks and a zombie crashes into the classroom, triggering panic. The twist: another student is already infected and suddenly transforms, revealing the outbreak has started from inside the classroom. Students rush for the exit while the teacher grabs a heavy wooden bench and fights back. Several students join her, using chairs and desks to defend themselves. They eventually knock down the attacking zombies and the room falls silent. Just as everyone thinks it's over, a faint zombie groan comes from the hallway outside. The teacher slowly looks toward the blocked door. Cut to black. Photorealistic live-action, practical-effects horror, realistic Japanese classroom, natural handheld camera, authentic reactions, realistic physics, diegetic sound only. No music, narration, watermark, excessive gore, graphic injuries, animation, anime, cartoon, CGI look, distorted anatomy, subtitles, or random text.
