Ume Tachibana, wife of Sakuzō Tachibana, forms half of the elderly couple discovering Lalabel upon her arrival in the human world. She and her husband provide shelter and care for Lalabel within their home. Ume welcomes Lalabel with maternal kindness, treating her like family and personally crafting Lalabel's signature pink dress, showcasing her nurturing spirit and domestic abilities. Embodying a kindly grandmother figure, Ume consistently shows warmth and affection towards Lalabel and her granddaughter Teko. Despite her age, she occasionally joins the younger girls in modern activities like volleyball and tennis. Alongside Sakuzō, Ume acts as a parental figure, offering stability and guidance while Lalabel learns human customs, remaining entirely unaware of the girl's magical powers. Sharing responsibility for Lalabel's well-being with her husband, Ume helps create the supportive home environment crucial for Lalabel's integration into human society. Her role and background remain consistent throughout her documented appearances.
