Kazuma Kiryu is not a man that you want to mess around with. He's been through quite a lot of crap, as the first two Yakuza games demonstrate. He's beaten up government officials, Yakuza bosses, killers, men in diapers (yes. Men in diapers), regular thugs, big thugs, red thugs, blue thugs, basically half the people in Tokyo. After the events of the second game, he moved on to run the Sunshine Orphanage, but events conspire to bring him back into the seedy underworld of Japan to once again show that he is not to be messed with.
