Raised as and initially assumed to be a boy, Robin is actually a girl in disguise, and she had actually wanted to study to be an artist. In order to disguise her true gender, Robin adopted a masculine-coded voice and wore both the boys' uniform and an exercise brace. Despite her preference for art over law, she became the top student of the prosecutor course in her senior year.

After her true gender was deduced in court, Robin started living openly as a girl.
