Elite Yankee Saburo(2007)

Elite Yankee Saburo is a comedy series based on Abe Shuji's manga, following Ookochi Saburo, a plain and shy high school freshman played by Ishiguro Hideo. Saburo's two older brothers left behind a fearsome reputation as legendary troublemakers at the same school, and when he arrives, he's instantly mistaken for an "elite yankee"—a delinquent from a wealthy background. The mix-up sets off a chain of misunderstandings as Saburo navigates high school life trapped in a false identity he never asked for. Caught between his genuine nature and the dangerous reputation thrust upon him, Saburo must find his way through the chaos his brothers left behind.
