Saori Yasuda

Saori Yasuda (安田 沙織, Yasuda Saori) is a student at Kaimei High School and a member of the Broadcasting Club. She attended the same middle school as Sakiko Takashima, and was responsible for blackmailing the latter during the "Glass Man" incident. They had both been in love with the same boy in middle school, but she witnessed her love letter being taken from the boy's shoe locker by Sakiko and replaced with Sakiko's own. Additionally, they both fell in love with Eiichi Hiraizumi once in high school, and Saori was overwhelmed with jealousy that he only dated Sakiko. Despite her confession as the ultimate culprit of the "Glass Man" incident, the Sket Dan didn't reveal her involvement and instead took the blame themselves.
