Raina Kitamura

The bassoon and oboe section leader at Kitauji High School. Kurumi is a third year student who plays the bassoon but marches with pompoms during parades. She is the tallest female member, and among the tallest in the entire band. Kurumi is often seen with her close friend Mikino Oka, the other third year bassoonist at Kitauji High.

In her appearances throughout the episodes, Kurumi's face often has a serious or passive expression. However, she is shown with a bright smile while marching the parade.

As a side character, she has a very small role in the anime series. While she was present at the section leader meeting in episode 4, she did not voice an opinion. She is shown speaking a line in the background during episode 7.
