Miu Imazu is a supporting character in the anime Tsukigakirei. She is a third-year student at Kawagae Municipal Third Junior High School and a classmate of Akane Mizuno. She is a member of the track and field club alongside Akane and Chinatsu Nishio, and is also a ghost member of the brass band club. Miu has short, dyed hair and a fashion sense that is more mature than many of her peers, often giving her a stylish appearance. Her personality is assertive and socially confident, which contrasts with the more reserved protagonist Akane. She can be demanding and even greedy when she does not get what she wants, a tendency she often directs toward a classmate named Inaba without realizing how it annoys him. Despite this, she is genuinely kind to her close friends, including Akane, Aira Miyamoto, and Setsuko. She has a strong sense of her identity as a girl and can be whimsical, sometimes causing minor trouble for those around her. In the story, Miu serves as a narrative foil to Akane, representing a more worldly and experienced middle schooler. She frequently offers romantic advice and commentary on the developing relationship between Akane and Kotaro Azumi, often providing a more assertive perspective. Her role is primarily that of a supportive friend who helps navigate the social dynamics of her friend group, and she remains a steady presence throughout the series without undergoing a major personal arc.
