Ayame Osaki

A second-year at Sakaneko High School, and the student council vice president. While she has authority, she has a tendency to go charging off on her own, though Matsuri often calms her down. She practically worships Tsubaki and her strong sense of duty. Because the anime research club has Tsubaki's constant attention, she feels jealous toward Erika, and sees the club as her mortal enemy.
