Kanade Hisaishi (久石 奏,Hisaishi Kanade?) is a new first-year at Kitauji High School. She joins the band as an euphonium player in Kumiko's second year.
Kanade is a teenage girl with a short stature, fair skin, and cherry red eyes. She has black short hair which she wears in a bobbed haircut with straight bangs covering her forehead. She decorates her hair with a small red ribbon.
Kumiko describes her as a "hypocritical courtesy", or a girl who is "superficially polite but rude in intent".
