Ever since he was born, Baki Hanma has always known nothing but fighting—strengthening every single muscle and learning different techniques from various martial arts under the supervision of his mother, Emi Akezawa. He trains in order to prepare himself to face and eventually surpass his own father, Yuujirou Hanma, a man feared by the masses as the "Ogre" and deemed the strongest being in the world. However, when Baki realizes his mother's techniques are no longer enough, he sets out to become stronger in his own way. Seeking out powerful opponents and forming unbreakable bonds with them, he continues to grow both body and his soul, as the clock continues to tick closer toward the inevitable showdown against his father... Doppo Orochi sits down to watch the final match of his karate schools youth tournament. Atsushi Suedou, one of his disciples, faces off against Baki Hanma, a fresh teenage boy breezing through the matches. Intrigued by the boys strength, Doppo, alongside another of his disciples—Kiyosumi Katou— visits the notorious Tokugawa underground ring—a hidden freestyle fighting arena that prohibits only weaponry in its matches. Upon arriving, they learn that Baki is set to face none other than Koushou Shinogi: an infamous karate master and user of the lethal Cord-Cutting technique.
