岡峰 美紀恵

Holding the rank of Private, Mikie is described as having brown eyes and hair, with her hair tied in pigtails. She is in Origami's and Shido's year but she skipped a grade, making her one year younger. Her age being close to Origami's leads her to have a strange attraction to Origami. Her dedication to Origami is shown by the fact that she was willing to resign from the AST when she thought Origami was going to have a disciplinary discharge.
