The character known as Mère d'Haïda or Haida’s mother is the mother of the hyena office worker named Haida and his younger brother Jiro. She is a minor yet notable supporting figure in the later seasons of the anime Aggretsuko. Her background is defined by a long, unhappy marriage to Juzo, a domineering and verbally abusive politician. Unlike her harsh and controlling husband, she is portrayed as a gentle, soft-spoken, and loving parent. However, her kindness exists within a deeply constrained life: she is emotionally and verbally subdued by Juzo, and she lacks the agency to leave the marriage. Fan discussions and narrative clues suggest she stayed primarily out of fear that her husband’s influence and connections would allow him to win custody of their sons if she attempted to separate. This forced her to remain in a patriarchal household where she could only be a quiet, accommodating presence.

Her personality is marked by a warm, maternal tenderness, but also by a deep-seated passivity. She rarely expresses her own needs or confronts her husband, instead enduring his treatment in silence. Her motivations are centered on her children’s well-being; she sacrifices her own freedom to keep some semblance of family stability for Haida and Jiro. In the story, she appears primarily in the fifth season, when Haida’s relationship with Retsuko forces him to examine his family dynamics. Her role is to illustrate the toxic environment Haida grew up in and to provide a sympathetic contrast to Juzo’s harshness. She embodies the consequences of long-term emotional abuse and the difficult choices a parent may face.

Key relationships shape her character. With Juzo, she is subservient and silenced; he treats her dismissively and she rarely pushes back. With Haida, she shows unconditional love and concern, but she is unable to offer him the strong support or independence he needs because of her own powerless position. She also appears briefly with Jiro, again as a caring but ineffectual figure. Her development is limited; she does not undergo a dramatic transformation, but her situation becomes clearer as Haida gains perspective on his upbringing. The series uses her to explore themes of marital duty, domestic abuse, and the difficulty of breaking free from a controlling partner. She has no notable abilities beyond her quiet endurance and her role as a homemaker. Her quiet strength lies in surviving a painful marriage while trying to protect her sons, even if she cannot shield them from every harm. The character leaves an impression of sadness and resignation, making her a poignant, if understated, part of the Aggretsuko world.
