Souma Nadeshiko

She is Shinichirō Asano's homeroom teacher, school nurse, and the big sister of Matsuri Souma who refers Shinichiro to the Shimazu family upon his inquiry into part-time jobs. She's shown to be lazy at times, but isn't without her moments of compassion. She's very knowledgable about magic and specters and is a master puppeteer. She can also be seen as a bit of a jokester and a pervert when she's seen flirting with Shinichiro on more than one occasion.
