Flash forward three years: Baki Hanma is now the champion of the underground arena. Mitsunari Tokugawa meets with Doppo Orochi, a great Shinshinkai karate fighter, and asks him to enter his son in the arena. Doppo finds Kiyosumi Katou, a former student, at his dojo beating up his fighters, and he introduces Katou to the arena. Baki trains for a fight at the boarding house where he is staying, where Kozue Matsumoto, the daughter of the woman who owns the house, has a crush on him.
