Isurugi, Yayoi

石動やよい

Yayoi, the president of the Aogiri High School Student Council, is a capable and attractive girl who vowed to avenge herself against Miou for trampling on her efforts. She devised plans to ruin the Survival Game Club, which ended with undesirable results. Due to her obsession with revenge, the student body believed she was in love with Miou and that they were dating.
In one of her schemes, she posed as a recently transferred high school freshman under the name Ishida Kanna to befriend Momoka. She later used this disguise to infiltrate the school cafeteria.
