Kazuya, who has been a female teacher of Heppoko, Miyuki, and a female teacher of Iron Mask, Maki, respectively. As the next target, I decided to defeat the school director, Yuri, and decided to use Miyuki. Her nephew, Kazuya, was Yuuri who had not punished the suspicion. It can't be helped to be told from her own mouth that she proudly committed Miyuki. What is the purpose ... I asked with a calm expression not to take advantage of my weaknesses, He was amazed at the innocence of her nephew who said he wanted to like his body, and her anger swelled. Wow, I understand ... I should take it off ... To protect the students ... With such a noble will Yuri bitterly stares at her own body, which she feels against her will.
