[Classic Revival SOD AI Remastered] What would ancient Japanese "torture" look like reborn in the modern era? Set in a co-ed school, this film introduces cruel new tortures never shown in the previous installment. Beyond the water torture of the "torture waterwheel," new torments like the "live loach hell punishment" and the "public mating punishment" are added, expanding the scale of torture far beyond the original. With enhanced production and expression, the world of torture is portrayed deeper and more realistically than ever before.
