Akatsuki, Nagisa

暁凪沙

Nagisa is Kojou's younger sister. She attends the same school as Yukina and is in class 3-C. She is a close friend of Yuuma Tokoyogi and gets along well with Yukina Himeragi and Kanon Kanase. Her mother is Mimori Akatsuki. She tends to be talkative with people she likes and is an excellent cook.
Four years ago, she nearly died in a train accident caused by demons. She remains traumatized whenever she sees a demon. In fact, she was traumatized after being possessed by "Root."
She first met Yuuma Tokoyogi after both Kojou Akatsuki and Yuuma retrieved her hat, which had gotten stuck on a branch at the edge of a cliff. Once they were safe, everyone introduced themselves.
