Ume Aihara (藍原(あいはら) (うめ) Aihara Ume?),[1] née Okogi (小此木(おこぎ)?),[2] is Yuzu's mother and Mei's stepmother. She is currently married with Shō Aihara.


She is a tall adult woman with neck-length black hair styled in swept bangs. She has somewhat similar facial features to her daughter Yuzu.


Despite her age and the fact she's a mother, she's childish, playful and immature, going as far as calling her husband a "tsundere",[3] and mocking Yuzu after she dyes her hair black despite being the one to tell her to.[4] She shows a more mature side sometimes, however.[5] Like Yuzu, she enjoys fashion and shopping.[citation needed]
