Akane no Hahaoya

Mrs. Tendo is the mother of Kasumi, Nabiki, and Akane, and the wife of Soun. She passed away many years ago leaving Soun to raise the children. It is never said how she died, but the family still thinks of her lovingly. After Mrs. Tendo's death Kasumi assumed a more motherly role and helped with household duties. (Source: Rumic World)
