Mitsuo Suwa's mother, known simply as Mom, is a supporting character in the anime Perman. She is a typical housewife who manages the household and cares for her children, Mitsuo and his younger sister Ganko. Her most defining trait is her sharp, persistent nagging, which she directs at Mitsuo whenever he gets into trouble or neglects his responsibilities. Her scolding is frequent and intense enough to immobilize not only her son and daughter but also her husband and even other adults such as teachers. This comedic exaggeration underscores her role as the domestic authority figure.

Her primary motivation is to keep Mitsuo out of mischief and ensure he behaves properly. She disapproves of the Perman team’s presence around him, likely because she associates their activities with the trouble he often encounters. Ganko often tattles on Mitsuo, prompting their mother to scold him, which reinforces the sibling dynamic and her role as the disciplinarian. Despite her strictness, she is a caring parent who wants the best for her family.

In the story, she functions as a grounding, everyday presence that contrasts with Mitsuo’s superhero adventures. Her character remains largely static throughout the series, with no significant development or change. Her notable ability is her formidable nagging, which can overpower anyone in earshot and serves as a running gag in the episodes. She has no superhuman powers, but her influence over her family is portrayed as nearly unstoppable.
