Mirai Momoyama is a cheerful and youthful girl with a soft, feminine appearance. She has large, round eyes that are light indigo in color, accented with flecks of sky blue, giving them a sparkling, expressive quality. Her hair is a vibrant peach-pink shade, styled into a high ponytail that curls at the end, with shoulder-length forelocks that mirror the curl. Her bangs are neatly parted into three sections, framing her face, and she has a distinctive curled cowlick on the side of her head.

Outside of her school uniform, Mirai typically wears cute and girlish outfits that reflect her Lovely-type idol aesthetic. Her fashion choices are often bright, pastel-toned, and styled with ribbons, lace, or heart motifs, in line with her signature brand, Sweet Honey.

Mirai Momoyama is a sweet-natured and energetic girl known for her cheerful disposition and caring heart. While she can be somewhat clumsy at times, she is always thoughtful and attentive to the emotional needs of those around her. Whenever her friends are feeling down, she does her best to lift their spirits often relying on her signature charm, the “Kira Smile”, a heartwarming expression she inherited from her mother. Unlike her mother, who wields it in moments of frustration, Mirai uses her Kira Smile to encourage happiness and spread positivity.

At the beginning of the series, Mirai is portrayed as someone who often goes along with the plans of others particularly her more outgoing friend, Emo due to her reluctance to inconvenience anyone. However, as the story progresses, she gradually gains confidence and begins to take initiative, demonstrating leadership and growth, notably during major events like the Jewel Auditions and the Princess Cup.
