Saya is Kou's sister in "Re:Live". She has a very odd and awkward character. She is his big sister and is going to school to become a nurse. She is also incredibly overly protective of her little brother and tends to smother him quite badly. She is very cute and sweet though, although sometimes a bit too close seeming to her brother, but she just genuinely cares for him. At one point in the story the story shifts to hinting that she may be the actual murderer and so there is a portion of the story that she needs to still sound sweet but with a very uncomfortably creepy hint to it as all.

I picture her having a very typical girly anime voice, the very cute and sweet sound to it. More of a mid-high range because she is in university though.
