Satowa is a first year student and the daughter of a famous koto family, Houzuki. She has been learning to play koto since she was little and has won many contests. Although she is a koto prodigy, Satowa was debarred from Houzukikai. She claims that she joined the koto music club because she wants to become known as "young virtuoso koto player that led a no-name school club to become number 1 in nation" when she makes professional debut. She loves koto.
