In the early nineties the atmosphere in Japan became more and more hostile towards "bishōjo" games. In 1989 serial killer Tsutomu Miyazaki was arrested and was revealed to be a consumer of "lolicon" manga, causing widespread opposition to pornographic manga, otaku and anything similar. In November 1991 there was an incident where a middle-schooler shoplifted an adult "bishōjo" game "", resulting in increased police scrutiny for makers and retailers. Several prefectures began classifying games as obscene and pulling them off the shelves.
