Ringo is a third-year student at Prefectural Sanada East Girls High School who serves as part of the school's student council. Although she holds a leadership position within her own institution, Ringo is still addressed with honorific "-chan" by members of the student council from Prefectural Sanada North High School. Despite being confident and assertive in some aspects, Ringo struggles with feelings of inferiority towards high school boys, which can sometimes lead to impulsive behavior and a tendency to be easily deceived. She is also described as somewhat absent-minded, making her more susceptible to trickery. In terms of physical appearance, Ringo feels self-conscious about her height but has a large appetite. Despite these perceived flaws, she enjoys popularity among her peers and often receives unwanted romantic attention from boys.
