Shiroko is a soft-spoken girl, who deeply cares for her friends, to the extent that she would do anything to help her friends towards their goal of revitalizing the school. Though she is generally calm and reserved, she hyperfocuses on certain interests and can sometimes be oblivious to how others would react to them. She often bikes and walks far more than regular people can keep up, thinking distances of 10s of kilometers are average for her. She fantasizes about robbing banks and sort.
