Description
Mirai Momoyama is a female human character beginning as a 13-year-old first-year student at Kirarigaoka Middle School. She ages to 15 by her third year and transitions to high school during the series. She possesses peach-pink hair styled in a long ponytail with curled ends and shoulder-length forelocks, indigo eyes flecked with sky blue, and stands 150 cm tall. Her family operates a food business, including parents (her mother exhibits a similar "Kira Smile" used differently, and her father bears the nickname Mr. Whip) and a younger sister, Hikari, with whom she shares a fandom of rival Anna Akagi.

Initially sweet, energetic, and somewhat clumsy, Mirai struggles with low self-esteem, frequently needing encouragement from her more assertive childhood friend, Emo Moegi, to engage in activities. This evolves as she gradually develops initiative, particularly evident during the Jewel Auditions and Princess Cup. A core trait is her ability to identify and nurture others' unique strengths. Her signature "Kira Smile" uplifts others, inherited from her mother. Her hobbies include making sweets and creating intentionally simplistic art, exemplified by designing the mascot KiracCHU, whose subsequent growth she supports. Shortcake and eel are her favorite foods.

Her journey starts when a challenge from Anna Akagi, combined with Emo's encouragement, leads her to debut as a Pri☆Chan idol. She co-founds the group Miracle☆Kiratts with Emo and initially their classmate Rinka Aoba. Rinka serves as their manager before becoming the third idol member. Mirai specializes in the Lovely idol style, favoring the Sweet Honey brand, with performances often highlighting singing. Her catchphrase is "Kiratto☆", accompanied by a characteristic arm wave.

Key professional milestones involve participation in seasonal events:
- Season 1: Focuses on establishing Miracle☆Kiratts' channel and building viewership through varied programs.
- Season 2: Enters the Jewel Auditions, winning the Diamond Idol title and earning the Diamond Coord after demonstrating exceptional growth in confidence and leadership.
- Season 3: Competes in the Princess Cup within virtual Pri☆Chan Land, aiming to become the Illuminage Queen by winning Illuminage Coords across park areas and performing in Pri☆Chan Castle.
Additionally, she participates in a virtual musical event, training her "Fateful Power" at Fateful Garden High School under Sadame Ginga's guidance.

Relationships drive her development. Emo Moegi remains a steadfast supporter, though Mirai evolves from reliance on her to making independent decisions. Rinka Aoba is valued for her managerial and later idol contributions. Her rivalry with Anna Akagi shifts from one-sided admiration to mutual respect as Anna recognizes Mirai's tenacity. Sara Midorikawa becomes a trusted friend whom Mirai assists in embracing hidden interests in cute things. Daia Nijinosaki, initially withdrawn, bonds closely with Mirai, eventually permitting first-name address due to Mirai's persistent encouragement. The mascot KiracCHU, her creation, symbolizes her creative input and receives her ongoing pride in its evolution.

Her theme color is pink, incorporated into coords like the Exciting Pink Jewel Coord, Diamond Jewel Coord, and various Illuminage Coords. Despite pink not being part of the rainbow spectrum like other main characters' colors, it reflects her Lovely-type focus.
