To train for his eventual battle against his father, Baki spars against an imaginary giant praying mantis he’s created in his mind.

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.

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.
