An extreme and shocking work centered on utterly selfish bullying, corporal punishment, and training—content difficult for ordinary people to comprehend. Schoolgirls, married women, and office ladies become victims, subjected to relentless, merciless spanking that captures their terrified expressions. Prolonged torment causes their buttocks to swell bright red and even bleed. Finding arousal in their battered, wounded appearances, the director intensifies the abuse, forcibly repeating spankings over and over. This intensely painful depiction powerfully captivates viewers, delivering a traumatic impact that leaves no one unchanged.
