Blood Drip Ignites Undead Chaos in Silent Japanese Classroom

Cinematic horror-action short film set in a Japanese high school classroom, natural realistic pacing, grounded practical-effects style, no over-acting. Classroom filled with wooden desks, students in uniforms, a chalkboard, fluorescent lights, windows with afternoon light. Natural handheld camera work, muted authentic color grading, all sound fully natural and diegetic — no music, no artificial sound design, just real classroom, fight, and impact sounds throughout.
>
> **[0-3s]** Extreme close-up on the teacher's (GIVEN IN REFRANCE IMAGE) chalk squeaking sharply across the board mid-sentence, then a sudden beat of dead silence in the room, all eyes subtly shifting upward — an unsettling stillness before anything happens.
>
> **[3-4s]** Close-up: a single drop of dark blood falls from the ceiling, landing directly on a student's open notebook, the soft wet sound of impact clearly audible.
>
> **[4-5s]** SLOW MOTION: the student's eyes widen in shock, head tilting slowly upward to look at the ceiling above him.
>
> **[5-7s]** The ceiling cracks violently, plaster and dust raining down with a loud crash as a zombie bursts through, crashing onto a desk, wood splintering audibly.
>
> **[7-9s]** It lunges immediately, sinking into the neck of the nearest student — a sharp, natural cry of pain, desks scraping as others recoil.
>
> **[9-11s]** Within seconds, the bitten student rises again — eyes milky white, veins dark across his face — now a zombie himself, guttural groaning as he lunges at the student beside him.
>
> **[11-13s]** Chaos erupts: students scream and scramble out of their seats, chairs toppling loudly, rushing toward the classroom door in a panicked crowd, footsteps and shouting overlapping naturally.
>
> **[13-15s]** The teacher turns sharply, grabbing a wooden bench, the scrape of it dragging off the floor audible, her breathing intensifying.
>
> **[15-17s]** She swings the bench hard into the first zombie — a solid, heavy impact thud, it crashes back into a row of desks with a loud clatter.
>
> **[17-19s]** She swings again, striking a second zombie down, papers flying with a soft rustle, another hard impact sound.
>
> **[19-21s]** A few students grab chairs and desk legs, joining her — wood scraping, natural grunts of effort as they strike newly turned zombies near the door.
>
> **[21-23s]** Quick intercut shots: a chair slams onto a zombie's back with a crack, another shoved into the chalkboard with a loud bang, teacher sweeping a third off its feet with a scrape and thud.
>
> **[23-25s]** The group fights back-to-back in the center of the room, desperate breathing, grunts, wood-on-body impacts, zombies falling one by one with heavy thuds around them.
>
> **[25-27s]** Final zombie lunges at the teacher; she sidesteps and slams the bench down hard — one final heavy impact, it collapses to the floor motionless.
>
> **[27-29s]** Wide shot: the classroom wrecked — desks overturned, papers scattered, zombies down on the floor. Heavy breathing fills the silence as the teacher and surviving students stand together, blood on their clothes and hands.
>
> **[29-30s]** Final shot: the teacher lowers the bench slowly, exhausted, natural exhale audible, dust settling in the sunlight through the windows. Cut to black.
