Description
Sara Midorikawa, a main character, begins as a second-year student at Kirarigaoka Middle School, advancing to third-year and high school. Her family includes her father, mother, and brother Taro Midorikawa. Physically, she possesses emerald-colored hair in a sharply angled cut featuring a distinctive long, curled cowlick, magenta eyes, and a tall, slender build standing at 163 cm, making her the tallest main character. She uniquely wears a blue necktie with her school uniform instead of the standard pink bow.

Her personality blends a cool, tomboyish exterior with rock-and-roll style. Often positioning herself in the background to ensure others don't evade responsibilities, she maintains a composed, calm demeanor. Girls are drawn to her charismatic presence, especially when she plays guitar. Despite her cool image, she harbors a deep, concealed adoration for cute and fluffy things, which she struggles to suppress. Overwhelming cuteness can cause her to lose composure, leading to unguarded affection. She reinforces her tomboy identity by using the masculine first-person pronoun "boku."

As a cool-type idol affiliated with Romance Beat, she performs in the groups Meltic StAr and later Miracle☆StAr. Her career involves wearing various coords like the Kiratto Coord, Jewel Coord, Cybercat Coord, and the Melody Fantasy Illuminage Sara Coord. Her talents include playing guitar and creating improvised songs, aligning with her hobbies. Her favorite food is steak, and she enjoys all coords. Her birthday is June 9, coinciding with Japan's Rock Day, and her blood type is O.

Key relationships define her. She shares a close childhood bond with Anna Akagi and Mel Shido. With Anna, Sara acts as a stabilizing force, frequently tempering Anna's impulsive behavior and preventing conflicts, especially with Emo Moegi. She deeply values her bond with Mel, shown through shared activities and support. She trusts Mirai Momoyama with her secret fondness for cute things, leading Mirai to help conceal it to preserve Sara's cool image. Her interactions with Rinka Aoba include mutual admiration and light ship tease. She shares a competitive dynamic with Suzu Kurokawa over who embodies the "coolest" idol persona, though Suzu privately acknowledges Sara's superiority.

Her background involves key events: the Jewel Auditions in season two and the Princess Cup in season three, where idols raised mascots using PriTamaGo devices to compete for Illuminage Queen. Her development navigates this dual identity—maintaining her cool, guitar-playing persona while gradually accepting her hidden affection for cuteness as her friendships deepen and she integrates more within the idol community. This evolution balances her innate rock-inspired charisma with the vulnerabilities she selectively reveals to trusted companions.
