In the opening scenes, Michiyo, the girl who is tortured by the Disciplinarians, escapes from them and hangs from the edge of the roof of the school building before falling to her death. From an aerial shot, we see a brief glimpse of the ground below her: rough gravel. In the next scene, after she has fallen, we see people cleaning up the blood from where she fell and died. But the cleanup takes place on paved driveway in the front of the school entrance, not at all matching the rough gravel we saw in the previous scene. Also, she fell straight down from the edge of the building, but the cleanup of her blood is taking place out in the driveway in front of the entrance - a good distance from the edge of the building.
In the scene where the police riot squad has overcome the barricade and is fighting with the girls, a cameraman can be seen on the right hand side during one shot.
