In Ikebukuro, unbeaten street fighter Ran Sakurai and his friend Kenji run a benriya operation called “Randys” to earn enough money to buy a haka for their dead friend Shinichi Hoshi. Randys is named after their hero, Randy Bass: the American baseball player who helped lead the “hard luck” Hanshin Tigers to a Japan series title in 1985. A benriya is basically a problem-solver that accepts payment to do anything you need done, and Randys specializes in helping the weak triumph over the strong, much like Randy Bass did with Hanshin. One day, they find out the feared leader of a team of badasses called the Giants, Takeshi, has returned to Ikebukuro to stir up trouble. He has only one goal: to beat the crap out of Sakurai. A dispute that began 4 years ago is about to be settled, but not before the streets of Ikebukuro are covered in blood.
