Kojou Akatsuki Edit

Their relationship goes beyond that of a teacher and student, though it is not romantic. Kojou frequently refers to her as Natsuki-chan, much to her dislike. They care for each other in a fashion that is best described as friendship. She is also one of the few people who knows Kojou is the fourth Primogenitor.
