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.

Chunhoo rescues his son Sukgi from his death sentence only to discover that the decades have finally caught up with him. His son despises him for his mother's fate and all the lost years. Chunhoo reveals to him the secret story of how he learned Shi-Nan-Joo. He tells of the tragic fate of his martial arts master Yoshi and the hunt for the mysterious enemy that took his eye, a masked man with no name or trail who wields the power to defeat Shi-Nan-Joo.

After saving his son's life, Chunhoo realizes that he can't hide his powerful warrior aura in even the seedy red light district of Busan. He resolves to stand and fight his hunters, but is tormented by the fear of losing Seogki's life amidst the very battles fought to save him.

The Emperor now lies bloodied and prone against Ki-Do-Ryu - the Japanese antithesis of the Korean martial art Shi-Nan-Joo. Horribly wounded, Chunhoo is all that lies in between his son Sukgi and the deadly blade of the Japanese master swordsman Matsui.
