Description
Natsuki Sasahara, one of three elementary school girls chosen as a magical princess idol, embodies Kaguya-hime from *The Tale of the Bamboo Cutter*. Her surname, Sasahara ("bamboo field"), reflects Kaguya-hime's bamboo forest origin, while "tsuki" in her given name means "moon," alluding to Kaguya-hime's celestial roots. She lives with her grandparents while her parents manage a kimono fabric business away from home.

Athletic and tomboyish, Natsuki excels at sports like soccer and box vaulting. She possesses a headstrong personality but struggles to express her true feelings openly, sometimes seeming dishonest or guarded about her emotions. Her small turquoise dragon Ma-Pet, Ryoku, often teases her about this lack of emotional honesty. She dislikes lies and becomes visibly upset by insincerity in others.

Chosen by the Fairyland Queen to save vanishing fairy tales, Natsuki receives a magic gem that becomes a dark purple heart bracelet, enabling her transformation into an older idol form. Alongside Ringo Yukimori (Snow White) and Leila Takashiro (Cinderella), she forms the group "Lilpri." Their mission involves collecting "Happiness Tones" through song performances to restore Fairyland's stability. As Kaguya-hime, her symbol is a crescent moon, and "costume cards" provide new coordinated outfits for each transformation. Her signature food is pudding.

Throughout their mission, Natsuki develops a close, supportive bond with Ringo and Leila. They face challenges such as concealing their identities after nearly being exposed by junior detectives and navigating magical mishaps, including an enchanted card forcing dishonesty in episode 35. She participates in group activities like a tokusatsu-themed dream sequence and a beach episode where she wears a spring green swimsuit. Her journey emphasizes teamwork, emotional growth, and embracing her role as a guardian of fairy tales.
