A first-year student at Matsuoka Girl's High School. She is seen by other girls as being strong, refined and gentle, however they're surprised when they realize that Fumi is actually very gentle and shy. Others have noted her for having pretty eyes and a soft, lady-like voice. She is often said to make "scary faces" when she is upset or irked. Despite her size, mature aura and sometimes foreboding presence, Fumi is somehow prone to crying.
After moving back to her home town, she quickly becomes friends with a girl from her youth: Okudaira Akira. Fumi used to live near Akira while growing up, the two being best friends from the young ages of five or six. Fumi relied heavily on Akira in kindergarten, as she is seen incapable of doing anything but crying until Akira comes to "save" her and take care of her. This has not changed much as she got older, as noted by Akira.
