Her legwear consists of navy thigh-high socks, the edges striped with a white line, and dark brown Mary Janes with silver buckles. Her school crest can be found printed in gold on her collar flap and her left sleeve. Sayaka has a cheerful, sweet, lighthearted, and supporting personality, expressing a kind demeanor and pleasant disposition, although it is unknown if this is only because of her status as an idol. Sayaka develops a bond with Makoto Naegi, whom she considers her friend, assisting him on every occasion in Chapter 1. However, she tends to hide her feelings when she is under great pressure by putting on her public persona. She cares greatly for her band members, and would not hesitate to do something if anything were to happen to one of them, including things that could hurt others. When pushed to her limit, Sayaka will do anything to achieve the goals she sets out, however risky her actions may be. After she watched Killing Among Loved Ones, she only thinks of how she could escape from the academy, even planning to betray Makoto.
