Description
Hikari Momoyama is a character in Kiratto Pri☆Chan and the younger sister of the main protagonist, Mirai Momoyama. She lives with her older sister and their parents, who run a bakery called Pâtissière La Peche.

Physically, Hikari has peach-colored hair and indigo eyes, resembling her mother and older sister. In the first season, her hair is styled in short, curled pigtails held by pale orange bows, with straight bangs bunched at the center of her forehead. Beginning in the second season, her pigtails become significantly longer and are tied with ribbons, with her forelock strands showing a slight curl.

In terms of personality, Hikari is notably mature for her age, though she still exhibits many childlike qualities. She is often blunt with her opinions and can be easily annoyed, even with her parents. This is most evident in her relationship with her older sister Mirai, whom she frequently teases and expresses doubt or concern toward. Despite this critical exterior, she is not intentionally mean and possesses a deeply caring and supportive nature toward her family, even if she struggles to show it openly. As a child, she enjoys typical activities such as playing, drawing, and taking naps, as she gets tired fairly easily. She also helps out at her family's bakery.

Hikari's primary role in the story is as a supporting character within the Momoyama family. She often acts as a pragmatic and realistic counterpoint to her sister Mirai's more dreamy and enthusiastic nature. For example, when Mirai first considers becoming a Pri☆Chan idol, Hikari comically predicts she will only get three followers, counting their mother, Mirai's friend Emo, and herself out of pity.

Beyond her family, Hikari has key relationships with her classmates, Devi Fudo and Luu Asuka. Together, they form a group called Oshama Tricks, who affectionately refer to her as Little Yama, a nickname that plays on her status as the youngest Momoyama sister. Although she sometimes appears reluctant, she demonstrates loyalty and a capacity for mentorship. On one occasion, she made great efforts to coach Devi and Luu for a performance to help a sick friend named Bugcchu, an experience that strengthened their friendship.

Throughout the series, Hikari shows gradual development, particularly in revealing her naturally supportive side. While she typically acts critical of Mirai's endeavors, she can also help mediate within the family. A scrapped concept for the show considered having her perform with the Oshama Tricks, but this was prevented due to production issues.

Regarding notable abilities, there is no detailed information about her having special powers or idol-related skills, as her primary function in the narrative is that of a young family member and classmate rather than a performing idol herself. However, she is noted to have a charming and attractive speaking voice, with a cute singing voice mentioned in the context of her early episode appearances.
