Natsu started her career as a teacher with ideals in education, but the gap between reality and the tension of supporting students for entrance exams was eating away at her. At first, she was satisfied just teaching without panties or bra, but her perverted behavior gradually escalated, flashing her nipples and pantyless buttocks to the students, and sticking nude polaroid photos of herself on the blackboard. Eventually, she began to expose her obscene behavior not only at school, but also on trains, in the library, etc. #YoroP
