A high school freshman Kayo is a member of the Aogiri High School Survival Game Club. She goes to the same class as Momoka Class C but wasnt initially noticed. She doesnt talk much. She admits that she has no interest in survival games but joined the club because of her love for cosplaying. She sews her own costumes. She once displayed her cosplaying talent to Momoka in order to start a conversation with her because she didnt want to seem like an otaku by suddenly bringing it up.
