Misora Hibiki is the main heroine of the Mega Man Star Force anime series. She is a famous young pop singer who becomes involved in the conflict between Earth and the FM-ian beings when she encounters the FM-ian Lyra. Together, they are able to undergo Electromagnetic Wave Change, transforming into the hero Harp Note, also known as Lyra Note. Misora is around eleven to twelve years old and is characterized by a strong, spirited personality. She is cheerful and mischievous, but also impulsive and quick to anger, often acting on her emotions without considering the consequences. Unlike her video game counterpart, her mother is not mentioned in the anime, and her primary motivation is the desire to sing songs she writes herself rather than performing compositions written for her by others. This drive for creative independence often puts her at odds with her manager and the demands of her idol career. Her role in the story is that of a central ally to Geo Stelar, the protagonist, with whom she develops a close friendship and a mutual romantic interest. She frequently assists Geo in battles against FM-ians and other threats, using her abilities as Harp Note to fight alongside him. Misora's key relationships include her bond with Lyra, who eventually chooses to break ties with Planet FM due to their friendship, and her rivalry with Luna Platz over Geo's attention. Throughout the series, Misora grows from a pressured pop star into a more self-assured individual who embraces both her singing career and her duty as a hero. Her notable abilities include the power to EM Wave Change with Lyra, granting her enhanced strength, speed, and the capacity to unleash sonic-based energy attacks. She is also shown to be surprisingly athletic, capable of feats such as kicking coconuts great distances and winning a pop star charity swimming contest. In the second season, she travels with Geo around the world to recover ancient OOPArts, remaining a key support and fighter. Her dedication to her friends and her determination to follow her own path define her character arc.
