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 she can. 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. Sayaka mentions that she often finds herself focused on a particular person but pushes these thoughts out of her mind to commit herself further to her idol career. She has an amazing intuition, as she can easily tell what people are thinking. She often joked about being psychic, only to admit that she was kidding later on.

If you could sound similar to her English VA, Monica Rial, that would be great, but it is not required!

I don't have any English VA examples as there is not many I can find on Youtube, so if you could try and match the dub voice, it would be great, but again, it is not necessary.
