Ayame is a freshman in high school and Ibuki's younger sister. She has a shy, tsundere personality and is acutely aware of her small breasts when compared to those of her siblings. It took a while for her to like Yoichi romantically and she tries to help him at times while saying it was for no particular reason. She is bad with household chores in general. She dislikes being compared to Ibuki as she is constantly overshadowed. She has kissed Yoichi twice while he was unconscious during the performance of the play (the first unintentional and the other intentional).
