I remember seeing some video where there were four heroines who set out to beat up any guys to prevent any chikan moments. They all end up getting brainwashed to enjoy it though and when it comes to the last one the end up setting all of the girls on her instead. I seem to remember that one of them was kind of ganguro style. The leader character of the women wore a long black dress. I've never come across this video again and have no idea how to find it. Any ideas what it is?
