Nadeshiko is Rin's homeroom teacher. She is single, attractive, and is frequently the victim of pickup lines, including from the Lord of Devils and Itsuki. It appears she has some martial arts training (being able to slice a bottle with her bare hand). She has a habit of dealing out very strong punishments such as writing 100-page reports and dragging a tire around the track for minor offenses.
