When a high-tech ninja from the Far East attacks Titans Tower, ROBIN, STARFIRE, CYBORG, RAVEN, and BEAST BOY spring into action and bring him down. But when Robin finds out the ninja was sent by a mysterious and menacing Japanese criminal known as BRUSHOGUN ... our heroes realize that the action isn't over -- it's just getting started. So the Titans pack their bags, hop in the T-Ship, and take off for Tokyo on mission to track down Brushogun -- and bring him to justice. But can our teenage heroes stay out of trouble in the City That Never Blinks? And can Robin solve the mystery of Brushogun before our villain takes down the Titans -- and destroys everything Robin is?
