Michiyo Gotoh is the mother of Hitori Gotoh and Futari Gotoh and the wife of Naoki Gotoh. She shares her daughters' bright pink hair and blue eyes, and her youthful appearance often makes her seem much younger than a mother of two. She possesses a gentle and caring demeanor, but beneath that soft exterior she also has a notably strong and somewhat eccentric personality, a trait she passes on to both her children. Her primary motivation is to support her socially anxious eldest daughter, Hitori, though her methods of encouragement are frequently unconventional and over-the-top. She tries to help Hitori by buying her fashionable clothes, only for Hitori to reject them out of anxiety and a sense of burden. In the story, Michiyo serves as a warm but comedic presence within the Gotoh household, often providing lighthearted relief through her misguided but well-meaning attempts at motherly support. She has a close relationship with both of her daughters, and while she clearly worries about Hitori's social struggles, she loves her unconditionally. Her notable ability lies in her unwavering positivity and creative, if sometimes bizarre, initiatives to draw Hitori out of her shell. Though she does not undergo significant personal development herself, her role highlights the family dynamic that grounds Hitori's journey and provides a source of both humor and comfort.
