Fighting Girl(2001)

Original title: ファイティングガール

Sayoko is a tough, 19-year-old with ambition, energy and nowhere to direct it. Her father clearly favors her blind 16-year-old sister. Junior college is unstimulating. She is fired from her part-time job in a dress shop because she is too diligent at catching shoplifters and slaps them around a bit when she does. Even her boyfriend opts out for a more docile girl, but Sayoko doesn't think she is tough enough.
