Kanade Hisaishi 久石奏

Kanade Hisaishi is a new first-year at Kitauji High School. She joins the band as a euphonium player in Kumiko's second year.

Kanade has a courteous personality and great communication skills, and gives off a good impression to everyone who sees her. However, she has a secret side to her always-polite demeanor. Kumiko describes her as a "hypocritical courtesy" or a girl who is "superficially polite but rude in intent".
