In the series
She is the ringleader of the girls who shave off Motoharu's beard. She is also highly concerned about not getting a boyfriend. She seems to have a crush on Hidenori's older brother, Yūsuke, who calls her "Tanaka", although it is later revealed she only wanted to date him in desperation of finding a boyfriend, claiming she could not imagine kissing him.
