Aono Remi is the mother of Aono Miki and Ichijo Kazuki. Following her divorce, she lives with Miki while Kazuki resides with his father. Remi operates a nail and hair salon on Clover Town Street and was once a well-known idol. Her appearance features chest-length pastel indigo hair styled in curled ringlet forelocks over her shoulders and long bangs brushed mostly to the right. She has slanted, dark-colored eyes and pale skin. Typically, she wears a ruffled shirt under a white jacket, a black mini-skirt or shorts, and black heels, adding a pink salon bag around her waist while working.

Remi enjoys playfully teasing her daughter Miki over minor matters and expresses clear concern when Miki behaves unusually. Despite the family separation, she actively maintains her relationship with son Kazuki, ensuring they spend time together. Her dynamic with Miki blends warmth with occasional strain. Remi supports Miki's aspirations, like her dream to become a model, and participates in family celebrations for her achievements.

Her background involves managing her salon and caring for her children amidst the challenges of post-divorce family life. She is noted as the franchise's first divorced parent of a Cure. Remi shares her given name with another character from a different series but has no further connections or developments in spin-offs, films, or other media beyond her established role.
