Dame Oyaji follows Damesuke Amano, a downtrodden office worker subjected to relentless bullying both at work and within his own home, where he holds no authority. Living with his wife, the fierce Onibaba, and their children Yukiko and Takobo, Amano endures constant emotional and physical torment. This manga, set in the 1970s era of Japan, challenges conventional family dynamics by portraying a household where the father is powerless and victimized.
