Kome-Kome is a fox-like Energy Fairy from the kingdom of CooKingdom, specifically the Energy Fairy of Rice. She appears in the crossover film Eiga Precure All Stars F as the fairy partner of Yui Nagomi, who transforms into Cure Precious. Kome-Kome has a pale pink, fox-like appearance with a magenta collar and a heart-shaped brooch. She is young, innocent, and highly energetic, often ending her sentences with the sound kome. She greatly admires Yui and wishes to grow up quickly to become a more capable companion.

In the film, Kome-Kome accompanies Yui from the start and is part of the Sky Team, which includes Cure Precious, Cure Summer, Cure Sky, and later Cure Supreme. Her main role is to enable Yui’s transformation into Cure Precious by providing magical energy; when they combine, Kome-Kome enters a rice‑ball form to channel that power. Throughout the story, she remains loyal to Yui and supports the group as they journey to a mysterious castle and confront the antagonist. Her close bond with Yui is the foundation of her actions, and she also interacts warmly with the other Precure teams she meets.

Kome-Kome’s development in the movie reflects her steady growth as a partner. Though still childlike, she shows bravery and a desire to protect her friends. Her notable ability is her role as a catalyst for Yui’s transformation, drawing on her own energy to empower Cure Precious. This bond allows them to fight together effectively and contributes to the group’s overall strength.
