She's a school supervisor for Sayama High which seems to be a rabbithole of never ending secrets. She's close with many people, such as Midori Lin and Misa Hinasaki. She has a green ponytail, and green eyes, and is always equipped with handcuffs incase something goes wrong. The last supervisor, Akane Maki, mysteriously disappeared, and Saori was elected in her place.
