She is a second-year student who plays the euphonium.
Natsuki is a young girl with auburn hair that is tied in a high ponytail with two strands sticking out from it and blue eyes.
She wears the standard Kitauji High School uniform for second years.
Natsuki is a reserved girl who is rarely seen talking, and she has an aloof and calm attitude. It is later revealed that the second-years are like this because of an event which occurred the year before Kumiko Oumae's first year at Kitauji.
However, Natsuki is normally friendly to everyone, and tends to be mature and calm in most situations. She is also understanding of situations and takes everything quite nicely.
