Young Yakuza 2007 ( 5.8)

Meet the Japanese Mafia's latest son: a 20 year old named Naoki, part of a surging, decade-long wave of juvenile delinquency in Japan. As Naoki rejects school, jobs and family, his desperate mother decides to take one last chance to save him--by handing him over to the Mafia for one year and letting him choose his own path.
