Height 140 cm Roko is a second-year high school student and a former child actor who struggles to find work. She was once loved by many for her role in a popular series of broccoli commercials. Despite being a sixteen-year-old high school student, Roko stands at only 140 centimeters (4-foot 7-inches) tall, a somewhat humble reminder of her ten years working as a child actor. Known by many TV viewers as "Brocco," Roko had joined Rat Productions after forcing herself out of the agency that kept pushing her to play the same character, which was already seven years passed its prime. After Fruit Tart was formed, Roko would eventually learn that she was in fact the group's leader. Roko has a younger sister named Chiko, who is a member of Cat Production's idol group, Cream Anmitsu. While her days of performing as a child actor are over, Roko has a tendency to still act rather childish and be brought to tears whenever something annoys her, such as the constant teasing from her sister, Chiko. She can be somewhat hostile to Hoho, whose incompetence and low-budget opportunities offered to the girls often infuriates Roko. Roko can be especially sensitive about her height and sometimes wishes to be at least a little taller than anyone of her peers. However, Roko seems to find solace in Nina's friendship, who shares the same high school, as well as similar insecurity. She is also a huge fan of Doki Kira, a long-running animated series for kids and a staple of her childhood. Roko is somewhat oblivious to the impact she has made on others through her role as Brocco, especially among her classmates. As an idol, Roko is very much popular among women in their 20's and older.
