Yui (Kanna Hashimoto) runs into the gyaru girls near a game center in Tenjin, where they persistently push her to join the Hakata Gyaru Alliance, leaving her in a tough spot. Just then, the police arrive. It seems that a salaryman who saw Yui and the gyaru girls mistook the situation for extortion. The gyaru girls protest, insisting they haven't done anything wrong, but the man judges them by their appearance and calls them scum of society.
