Yukina Himeragi's English Teacher
A woman who claims to be 26 years old, though fans often joke about the plausibility of that claim. She teaches English at Akatsuki Kojou's school, where she's generally competent if a bit mysterious about her actual age.
Beyond her teaching duties, she works with Itogami Island Security to investigate crimes involving supernatural beings on and around the island. This dual role—educator by day, supernatural crime investigator by night—is pretty much par for the course in her world, though most students have no idea about the second job.
