Speaking like a senile aunt, she enjoys playing around and napping more than work. Because of this, she usually gets scolded by the rest of the Committee. But, once the mission starts, she protects her comrades by fighting valiantly on the front lines. She acts very cool and is best friends with sensei, Shes also best friends woth Shiroko, ayane, nonomi, shrika, Aru, Mutsuki, and the others.

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 going on survival fishing trips, and being unable to do either of these things causes her to pout and act with remarkable petulance for how calm she usually is. Shiroko is willing to fight Hina the moment she laid eyes on her despite the head prefect's reputation, stopping only at Ayane's begging. She requires people like Sensei and Ayane to hold her back and keep her sensible. She also instinctively didn't like Wakamo for acting clingy towards Sensei, seeing how surprised Wakamo was at Sensei's presence
