Delinquent girls loitering at convenience stores or in the stairwells of mixed-use buildings aren't just killing time—they're asserting their presence, making a statement. They couldn't care less about bystanders. Smoking, shouting, doing whatever they please—staying true to their own style comes first. When a security guard on duty gets annoyed and yells at them for causing trouble, the delinquent girls react fiercely. The guard is forced to flee into the basement, only to find himself in far greater danger than he ever imagined. Men over thirty should never think about picking a fight with these girls—it'll only end in regret. For these delinquent girls, beating up an old man is nothing more than a game. It's their raw strength and sheer force that make this story so compelling. (Ryuko Ryutsu Dan)
