Chunhoo Kang lives in a world of crime, sex and intrigue. He's the Nihon Saikono Warrior, Japan's greatest fighter in the yakuza underworld. However, he's also Korean. Haunted by past sins, Chunhoo abandons his crime life to search for the young woman and son he forsook decades ago.
His yakuza bosses are unforgiving. Assassins trail him all the way back to Korea and Chunhoo resolves that he's not going to be anybody's servant anymore. He's going to become an Emperor, standing at the apex of his own empire.
Meanwhile, his son Sukgi is a rising hotshot in the Baekhwa criminal organization in Korea. He's got it all; money, women and power. But when the Baekhwas spark a national murder scandal, the mob boss forces Sukgi to take the fall by threatening his mother. To save her life, Sukgi must agree to take the fall, a certain death sentence.
Will father and son find each other? And who is the Emperor that Chunhoo seeks to become? Will he be for good or evil?
