Two tough kogals from a neighboring town try to take over Ran's turf! What happens when Ran loses her home court advantage after she and her friends stray several stops down the train line to another, slightly less popular area?

When Ran and her pals do some window shopping in nearby Ikebukuro, they run into a couple of formidable 'bukuro kogals, led by Honda Mami, self-styled boss of Ikebukuro, along with her best friend, Harue, who seems to have a past connection to Ran's best friend, Miyu. What starts as a minor accident escalates into a series of attacks on Ran and her friends.

Although their opening scuffle ends without bloodshed, it does set off a vendetta. While Mami schemes to take Ran down several pegs by taking over Shibuya herself, Harue tries dredging up Miyu's shameful past for her own revenge!
