A teacher named 'Shiraishi' works at a school in Tokyo. Born into a wealthy family, he was raised strictly from a young age. He graduated from a top university and became a clergyman as expected by his parents and siblings. Then he dedicated himself to work, and before he knew it, he was middle-aged… Although such is the case, Shiraishi has lived with a twisted desire in his heart. That is the wish to assault and train young girls… As his life approaches its twilight years, this desire explodes, and he lays hands on 'Nana,' one of his students! #YoroP
