Yoshie Manjoume is Fumi Manjoume's mother. She shares a notably warm relationship with her niece, Chizu Hanashiro, contrasting with her more distant connection to her own daughter. Despite Yoshie's attempts to engage with Fumi, she perceives her daughter as emotionally distant, attributing this to typical teenage behavior.

Her rekindled friendship with Shouko Okudaira, Akira Okudaira's mother, significantly influences the narrative. This renewed bond between the mothers directly paves the way for the reunion of Fumi and Akira after their ten-year separation.

No concrete information exists regarding Yoshie Manjoume's appearance, occupation, personal history beyond family connections, or involvement in events beyond facilitating the daughters' reunion. Similarly, no details are available about her character development across additional seasons, movies, OVAs, or spin-offs.
