Teacher vs Zombie: Japanese High-School Horror Sequence

Create a short, ultra-realistic Japanese high-school horror-action sequence featuring the female teacher from the reference image. She is teaching normally when a single drop of blood falls onto a student’s notebook. Everyone looks up as the ceiling suddenly cracks and a zombie crashes into the classroom, sending students into panic. As they rush for the exit, another student suddenly reveals he is already infected, turning the classroom into chaos. The teacher grabs a heavy wooden bench and fights back while several students use chairs and desks to defend themselves. They eventually knock down the attackers and barricade the door. Just as the room becomes silent, a deep zombie groan echoes from the hallway. The teacher slowly turns toward the blocked door as the handle begins to move. Photorealistic live-action, practical-effects horror, realistic Japanese classroom, natural handheld camera, authentic reactions, realistic physics, muted cinematic grading, diegetic sound only. No music, narration, excessive gore, graphic injuries, animation, anime, cartoon, CGI look, distorted anatomy, subtitles, text, or watermark.
