Tamade Miu

 is the mother of CHU². She is a world-class violinist who works and lives in the US with her husband. Ever since Chiyu was young, she had high expectations of her and forced her to learn different instruments such as the piano and the violin, as well as participate in different music competitions. She often sends different kinds of clothes to Chiyu, some of which have been worn by PAREO.
