Miki Suwa is a seventeen-year-old student and the leader of the revived Lemon Angel idol group. She was born on April 3 and has short brown hair and brown eyes. Unlike the other members, Miki did not audition for the role; instead, she helped create the Lemon Angel Project alongside her close friend Yui Kono, with whom she was good friends, much like she later becomes with Tomo Minaguchi. Miki presents a strict and outwardly stern demeanor, often coming across as arrogant or overly serious, but beneath that surface she is deeply caring toward the other Angels. Her sense of responsibility and leadership is central to her character, as she takes the project's success seriously and enforces discipline within the group. Miki has a personal hobby of taking photographs of train stations, which hints at a more contemplative side. She is shown to be a talented pianist and is closely involved in the musical direction of the group. Early in the story, she dismisses Tomo after a frustrating conversation at school, reflecting her no-nonsense attitude, yet over time she develops trust and bonds with the other members. Her key relationships include her partnership with Yui, her friendship with Tomo, and her role as the strict but protective figure for the rest of the unit. Miki does not undergo a radical personality change but instead gradually reveals her genuine warmth and dedication to the group's growth. Her notable abilities include strong organizational and musical skills, as well as the capacity to lead under pressure.
