If I had to judge by manga alone, it'd say Japan has a rapist per 100 square feet.
100 rapists and 500 subway gropers. (I understand both are real problems, and that gropers are more common than rapists IRL, but they're to a point of a cliche in manga)
I don't see this story as horrible, but as kind of lazy and ... demeaning to rape victims... most of whom don't make other peoples' lives hell after being assaulted.
