Ayahi Kimishima is an energetic rookie who recently joined Kisarazu City Hall's "Do Anything Division". In emergencies she uses the element of fire to become the phoenix-themed hero, Sparkle Fire. As a huge fan of superheroes and tokusatsu shows, Ayahi can get overly excited when she transforms to fight the Zaboon monsters, quoting superhero facts while the fight rages and reminding her teammates of scenes in shows that are similar to their current battle. However, she still fights with as much courage as the superheroes she idolizes.
