Is it is possible to lead the yakuza and be a high school teacher at the same time? Kuniko has always dreamed of being a teacher, but as the heir of the Oedo Group it isn't easy to do. Her task is made even more difficult because her school would fire her if they found out about her criminal activities.She has to pretend to be an ordinary teacher while fighting off rival yakuza, winning the respect of delinquent students and keeping her family business away from the school. This becomes even harder when her smartest and most curious student begins to find her very... "interesting".
