MC gonna have a tough time; rape is basically legal in Japan, as long as you say "she wanted it."
You beat the shit out of a 16-year-ild girl, rape her, leave her for dead, get caught... and as long as you say she was wearing "sexy clothes," or claim the "she wanted it," or even just tell people "she enjoyed herself" Japanese society will blame her for you raping her.
Hell, they will even turn it into a doujin, so people here can fap to it.
Basically, that part of Japanese society is like living in Republican-Jesus-Land.
