AOZ-188 Targeting a female college student living alone in Tokyo for a home invasion rape

Active female college students who came to Tokyo from the countryside. In a city where there is no communication between neighbors, it is impossible to distinguish between a suspicious person and a resident who enter the same apartment building. You can't even spot a rapist disguised as a courier. Even if you are followed from the nearest station and attacked the moment you open the door, you cannot escape. Their calls for help are drowned out by the hustle and bustle of the city.
