Filming without consent is a serious crime and must never be done—we repeatedly emphasize this. To help those women suffering from the pain and trauma caused by hidden camera recordings, big-titted AV actress Mizuki Sanada, loli-busty idol Mai Imai, and the editor-in-chief of Monthly Radio Life have joined forces to investigate the methods and prevention of hidden camera crimes. What types of covert filming are actually used? What do the recorded videos look like? What dangers and harms are involved? We will thoroughly examine these issues, aiming to prevent this despicable crime before it happens and work together as a society to eradicate it completely.
