Dame Oyaji follows Damesuke Amano, a beleaguered office worker who endures relentless bullying at work and, even more severely, at home. He shares a household with his wife Onibaba, his attractive teenage daughter Yukiko, and his elementary‑school son Takobo. Onibaba is a domineering, violent woman who frequently berates and physically assaults her husband, finding pleasure in making his life miserable. Yukiko and Takobo often participate in both the physical and psychological abuse directed at Amano. The original manga was noted for its shocking content.
