Natsuki Nakagawa

Height: 156 cm
Instrument: Euphonium

Natsuki is a reserved girl who is seen rarely 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.
