To gain the skills he needs to surpass his powerful father, Baki enters Arizona State Prison to take on the notorious inmate known as Mr. Unchained.
The world is shaken by news of a man taking down a monstrous elephant with his bare hands. Back in Japan, Baki is confronted by a knife-wielding child.
To train for his eventual battle against his father, Baki spars against an imaginary giant praying mantis he’s created in his mind.
In the middle of a heavily guarded parade, the President of the United States is kidnapped in plain sight by an unknown young man.
Baki comes across a man known as “Mr. Second,” a powerful inmate who seems to enjoy special privileges within the prison.
With just a few weeks left on his sentence, Iron Michael is attacked by triplet hit men hired to make sure the ex-boxing champ never fights again.
Just as the Mouth triplets are about to finish their attack on Iron Michael, Guevaru rolls in and instigates a fight.
Guevaru refuses to believe that Biscuit Oliva, the most notorious inmate in the prison, is comfortably serving his sentence in the company of his lover.
The match between Guevaru and Oliva begins, and the rules are simple: They both hold onto the same piece of cloth and the first one to let go loses.
Guevaru is fighting for the people of his impoverished homeland, and he won’t go down so easily. Later, Oliva makes a discovery.
Baki is surrounded by guards with their guns pointed right at him, but he doesn’t seem worried at all — he seems to be planning something.
Oliva inadvertently kicks off a major incident when he enters Baki’s solitary confinement cell to challenge him to a fight in two weeks' time.
Baki learns the hard way that he might not be ready to fight the man known as “Mr. Unchained” — Oliva’s power and technique are on another level.
