Nanami Nanakusa is a supporting character in Love Live! Superstar!!. She is a third-year student at Yuigaoka Girls' High School and remains at the school until she graduates in the series finale. In the second season, Nanami becomes the treasurer of the student council. Her full name is revealed in the eighth episode of that season. She is often seen in the company of Yae and Kokono, suggesting a close friendship with them. Nanami appears across all three seasons of the anime as a background figure within the school community, primarily fulfilling student council duties rather than participating directly in the school idol group Liella!. Her personality is not extensively detailed in the available material, but her role as treasurer implies a responsible and organized nature. Beyond these established facts, little is documented about her personal background, deeper motivations, character development, or any notable abilities.
