She is a sweet and shy girl who acts in the school theater club. She has a passion for acting but feels uncomfortable with improvisation and her appearance. She is self-conscious about her underdeveloped figure, unruly hair, and, in the manga, her freckles, which make her feel insecure about not having a mature-looking body. Her insecurities are heightened by living with her roommates, Ayaka Yukihiro and Chizuru, both of whom have more mature figures and larger busts. Kotarō, who also lives with them, pretends to be her younger brother, a role imposed on her by Chizuru. Despite this, Natsumi seems to be adjusting well to her new role as an older sister.
