With great martial arts skill and a blade hidden in his boots, he butchers a bunch of enemies into mincemeat in the blink of an eye. His arch enemy is Kakihara, a yakuza boss who's tired of everything, including himself. Only when he pierces, cuts, and burns his own and other people's bodies does he feel that he is alive.Warning: Very graphic content.
