Natsuki is Kojō's English teacher and an attack mage. Despite claiming to be 26 years old, she has the appearance of a grade school girl. She is usually seen wearing a gothic lolita dress. She is one of the few people who know that Kojō is the 4th progenitor. She is high ranking mage and is called "The Witch of the Void". It is later revealed that she is actually the guard of the magical prison barrier that houses the most dangerous supernatural criminals; her actual body is sealed deep within the prison, while the teacher and mage everyone interacts with is actually an illusion. Kojō, Aiba, and Yaze usually call her "Natsuki-chan" despite her repeated demands to address her as "sensei."
