GUTI: The First Crew Member

After Sabo is kidnapped back to his birth parents, Luffy has a hard time adjusting to life without him. When things get too much, the 15-year-old seeks freedom through brawling in the back streets of Four Blues City. But this time he's bitten off a little more than he's used to. Who's the crazy, green-haired punk with the sword? And why does it sound like Smokey's got a collection?
