Kotobuki Ran, who styles herself as the Kogal queen, and her friends simply want to have fun. This includes shopping, hanging out, and scamming meals off gullible guys. Unfortunately, their "hood"—Shibuya—is in constant danger of being despoiled by dirty old men, street gangs, nasty Kogal rivals, and other societal evils. But with a little help from her friends and a toughness born of coming from a family full of cops, Ran takes on the bad guys (and gals) with gusto!
