Natsuki has dark brown hair with two odd spikes sticking upwards on the right side of her head. Her bangs are styled to the right. She has black, circular glasses with brown eyes.
She wears the standard teacher uniform: a brown patterned shirt, a grey blazer, black leggings and light gray high heels decorated with blue bows.
She is a faculty member at school. Natsuki has the Strict persona and had extensive martial arts training. If a camera is pointed at her, she will have a suspiscious look on her face.
Natsuki doesn't have a routine yet, so she stays in Class 1-2 all day unless a student informs her of a murder or she is chasing Yandere-chan.
