A tremor runs through the world at the report of a man who felled a monstrous elephant with nothing but his hands. In Japan, Baki faces an unexpected challenge: a child armed with a knife.

Preparing for the inevitable confrontation with his father, Baki engages in solitary sparring, his opponent a colossal praying mantis conjured from the depths of his imagination.

Amidst the solemn procession of a heavily secured parade, the President of the United States is seized, unexpectedly, by a young man of unknown origin, the event unfolding before the eyes of onlookers.

Baki encountered a man called "Mr. Second," an inmate of considerable power who appeared to enjoy certain advantages within the prison walls.

Michael "Iron" Harding had a scant few weeks remaining of his time inside when the assassins came. Three of them, they were, dispatched with a single, ruthless purpose: to ensure the former boxing champion would never step into a ring again…

As the Mouth triplets prepared to overwhelm Iron Michael, Guevaru arrived and ignited a new conflict.

Guevaru struggled to accept the reports: Biscuit Oliva, the prison's most feared occupant, was seemingly enjoying his confinement, kept company by a lover. It seemed impossible.

The contest between Guevaru and Oliva commences, governed by a straightforward premise: each grasps a shared length of fabric, and the first to release it is declared defeated.

Guevaru battles for the sake of his people, those living in poverty within his homeland, and will not yield easily. Subsequently, Oliva makes a significant discovery.

Guards, weapons trained on him, encircled Baki. Yet, he displayed no apprehension; instead, a subtle calculation seemed to animate his features, as if he were already charting a course of action.

Oliva’s casual challenge, delivered during a visit to Baki’s isolated cell – a mere two weeks hence – ignited a significant disturbance.

Baki discovered, with a painful clarity, that he might be outmatched against the man called "Mr. Unchained." Oliva's power and skill existed on a plane entirely beyond his own.
