Akari is a teenage girl with long brown hair that are styled into two ponytails help by hair ties with red spheres and red eyes. She wears a Kisaragi Academy schoolgirl winter uniform consisting of a dark blue blouse attached with a sailor-styled collar, long sleeves, and a pleated skirt with a yellow neckerchief. She also wears brown shoes.
One of Yoshiki's students who bears a strong resemblance to his high school crush, Ayumi. Her gloomy mannerisms cause her to be frequently bullied. She also knows how to play piano, but only if she can see the notes.
Akari and Ayumi are similar in height.
Yoshiki would comment, “Their statures are just…” Akari looks strikingly uncanny to Ayumi; their visages could easily overlap each other.
