Ase is a friendly, yet anxious and insecure girl. She has a poor self-image due to her chronic sweating issues, which she believes others will judge her for. She felt that her sweat causes a disturbance to others, and generally tended to avoid people during her initial appearance. She didn't want anyone to accidentally touch her, fearing that they would get their hands dirty. Later, she tries her best to overcome her inferiority complex and becomes friends with Komi and the others. She is childhood friends with Isagi Kiyoko and started to be self-conscious about her sweating disorder after being snapped at by Isagi back in middle school. They reconcile afterward and end up as best friends. She also seems to have developed feelings towards Naruse Shisuto.
