Ryoko Akiyama

Ryoko seems to be a superficial and ironic girl. She claimed that she likes "that kind of thing", referring to the class curse. Also, Ryoko gathered information about the curse and the calamity from ex-students from class 3-3 and researched about it and believes it, claiming that "a lot of students have died", even if she isn't affected by it. She is a joker person as she likes to scare Reiko Mikami with the curse.
