Goutokuji, Kayo

豪徳寺かよ

Kayo, a high school freshman, is a member of the Aogiri High School Survival Game Club. She shares Class C with Momoka, though she initially went unnoticed. She speaks little. She admits to having no interest in survival games, having joined the club solely due to her passion for cosplaying. She sews her own costumes.
She once showcased her cosplaying skills to Momoka to initiate a conversation, as she did not want to "seem like an otaku" by bringing it up abruptly.
