Baki is bored. After the conclusion of the epic battle between father and son, he continues to fight in the underground arena and train nonstop, but he always has to suppress the yawn caused by overwhelming boredom. No amount of stimulus or danger can bring excitement to him at this point. Now, with the Prime Minister of Japan involved, a massive cloning project is attempting to clone Miyamoto Musashi, one of the fathers of Japanese martial arts. Another fight of historical proportions awaits Baki.
