Rika Saotome serves as a police officer assigned to the police box fronting Kameari Park. She holds intense hostility toward her colleague Kankichi Ryotsu, primarily fueled by his habitual antics and disruptive behavior. She collaborates closely with fellow female officers, frequently devising strategies to thwart Ryotsu's interference in their planned events and activities.

She maintains positive relationships with the other female officers at the station. Together, they reside in a French chateau-style luxury dormitory.
