It was bad luck for Hanaka because she moved to a school where 80% of the students were boys, she felt that something scary was coming to her when she was here, what Hanaka didn't expect was that scary thing came much earlier...
From the first day of class, Hanaka was noticed by the boys and after the first lesson, she was intimidated and luckily the invigilator who passed by discovered and stopped her in time. But, the overseer himself was a bastard, after the boy left, he "jumped" into raping Hanaka even though she knelt down and begged for forgiveness.
Of course, the cute schoolgirl has just started her journey of... rape, let's continue to watch the movie to see if Hanaka is fucked by anyone else...
