While Baki easily subdues the thugs hired by delinquents from his own school, death row escapee Spec pays a visit to assess the champion's abilities.
Death row escapee Dorian barges into the Shinshinkai Dojo and is confronted by Sea King Retsu, who's there coaching students in Chinese martial arts.
With all five death row escapees and their opponents assembled inside the underground arena, Tokugawa officially declares the beginning of battle.
While out with Kozue, Baki is almost ambushed by Spec, but he' s spared a fight when Kaoru suddenly appears to protect the couple from harm's way.
Spec unleashes moves lethal enough to take out even the strongest of opponents in one strike, but Hanayama counters with improbable moves of his own.
Ambushed by Doyle while in class, Baki leads Doyle away from the classroom only to encounter Yanagi in disguise outside.
While Baki and his allies discuss the events that transpired at his school, Dorian appears, infiltrating Tokugawa's heavily guarded compound.
Kiyosumi Kato, known as one of the strongest fighters of Shinshinkai Karate, confronts Dorian deep inside his secret underground hideout.
Boasting one million members nationwide, the Shinshinkai lures Dorian to an amusement park, where Kato's peer Suedo immediately strikes.
As Dorian's past comes to light, Shinshinkai founder and "tiger killer" Doppo Orochi takes him on in an all-out karate versus kempo battle.
Doppo Orochi pummels the life out of terror-stricken Dorian before bringing the equally injured Kiyosumi Kato over to administer the finishing blows.
