Mother is a supporting character in the animated film Tokyo Godfathers. She is the owner of a hostess club in Tokyo, a venue where women, including transgender women and drag queens, perform songs and dances and socialize with customers. Mother herself is a drag queen, and she became the foster parent of Hana, one of the film's three main protagonists. Having grown up in foster care as an abandoned child, Hana was taken in by Mother, who raised her and later employed her at the club. Mother thus serves as a maternal figure in Hana's life, providing both a home and a sense of belonging within the club's community.

In terms of personality, Mother is portrayed as a nurturing and pragmatic person. She runs her establishment with a firm but caring hand, offering a safe space for women who might otherwise be marginalized. When Hana returns to the club years after leaving in shame—having assaulted a rude customer and then lost contact after her lover's death—Mother welcomes her back without reproach. This gesture underscores her forgiving and supportive nature. Her motivations appear rooted in a desire to protect and uplift those who, like Hana, have been cast aside by society.

In the story, Mother appears during the second half of the film, when Hana, along with her companions Gin and Miyuki, seeks shelter after a series of ordeals. The club provides a temporary refuge and a moment of emotional release for Hana, who confides in Mother about her past and her longing to become a mother herself. Mother's presence reinforces the film's theme of found family and the resilience of queer communities.

Her key relationship is with Hana, whom she raised as a daughter. There is a clear bond of mutual respect and affection between them, though Hana's shame over her earlier departure kept her away until the events of the film compel her to return. Mother also maintains a professional relationship with her employees, including other drag performers, and is portrayed as a respected figure within the club.

Mother does not undergo significant personal development within the film; her role is largely static, serving as a supportive anchor for Hana's journey. Her notable abilities include running a business, performing as a drag queen, and fostering a caring environment for those in need. She embodies a non-biological, chosen motherhood that contrasts with the film's other maternal figures, such as the troubled Sachiko and Hana's own absent biological mother. Through her, the film illustrates that maternal love can exist outside traditional family structures.
