She serves as the President of the Literature Club at Matsuoka Girls' High School. Given the club's small size, she enjoys a close relationship with Fumi, often seen together engaged in club activities like reading books and having tea.
She is a close school friend of Sugimoto Yasuko and is well aware of her popularity, frequently teasing Yasuko about being "Mr. Matsuoka-sama". She appears quite exasperated by Yasuko's presence in the club, as potential members tend to leave and join Yasuko in the basketball club instead.
