[SIyahkah MIzOnO]”Super Duper High School Level Idol"

Voice: high-medium high

Personality: Seeing as she's an idol, Sayaka has a cheerful, sweet, and supporting personality. Sayaka develops a bond with Makoto, 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 also cares greatly for her band members, and would not hesitate to do something if anything were to happen to one of them. Sayaka has an amazing intuition, as she can easily tell what people are thinking. She often joked by telling people she was an esper, only to admit that she was kidding later.

Background: She is the singer of a popular girl group in Japan. Her fans call themselves "Sayakers".

She used to be in the same junior high school with Makoto Naegi, though the two never got a chance to talk to each other until the murders at Hope's Peak Academy occurred.
