Every warrior's life is but a moment. These fearless fighters exist knowing all too well that each moment could be their last. There is always someone stronger, or faster. It is this great unknown, this passion for power that drives the Grappler.

Yujiro Hanma wreaks havoc in the ring as Baki ushers in the first match of the Quarterfinals. However, both immediately encounter the unexpected. While Yujiro is caught off guard by his opponent's strength, Baki is confronted with the most difficult decision of his life.

Baki's father pays a daunting visit as the next round of the tournament begins: the lethal semifinals. Baki will have to fully utilize his hidden talent if he is to have a chance against his opponent, a master of the sacred Kung Fu discipline.

The ultimate showdown is at hand. Baki steps into the ring, and the agreement is made that only one fighter will walk away. As devastating blows fill the arena, Baki's opponent begins to twist and gnarl into an unimaginable monster. Suddenly, the terrifying truth surfaces... Baki may not survive the fight.

While studying up on his future competition, Baki soon discovers the true terror that is Kaoru Hanayama, a cold-blooded monster bent on the excruciating end of all who stand before him. Hanayama does not use weapons. He is a weapon! And now, events are set in motion that will bring the full might of the killer's colossal strength bearing down on Baki. However, what Baki doesn't realize is Hanayama means to fight this battle to the death!

Baki is back! And this time, he's faced with his greatest challenge yet: a head to head battle with his father. With impossible odds weighing against him, Baki knows that his father, the undefeated Yujiro Hanma, will do anything to win. Now, with only one month to prepare for the fight, he must push his body and mind to the limit or die by the same man who gave him life.

It's Baki vs. Yujiro in a no holds barred grudge match to determine superiority once and for all! Or is there much more at stake than meets the eye? Whose side will Emi choose: The man she loves or the son who desperately wants to love her?

Baki has become the champion of an underground circuit known for employing some of the best fighters in the world. Tokugawa, the commissioner of the circuit, throws the best competitors he can find in Baki's path, to no avail: The Champ seems invincible! But two incredible adversaries await.

The King goes underground! When Yujiro appears in the underground arena and quickly humbles his champion son, he accepts a vigorous challenge from the patient Doppo. Doppo's secret ten-year vendetta is exposed to the younger generation's champion - as well as his tremendous abilities as a grappler. But Baki must remain focused...

Baki Hanma returns to the Supreme Fighting Circuit to defend his title against a sea of contenders. The quest to find the most supreme grappler in the world moves forward with unimaginable results. A monstrous secret is about to be unveiled in the arena; one which could bring about the ruin of Baki and every warrior in the competition!

Baki has fought his way to a new level in the circuit where legendary fighters are gathering and the only rule in the ring is fight or fall. Every warrior thinks they're ready. But with Yujiro's protege making his debut, the Tigerslayer's return and the arrival of the toughest man in the world, the challenge won't be just to fight... but to stay alive.

The championship begins as dark revelations and untamable rage fill the arena. In a tournament for honor and glory, a horrifying force rises that fights for neither. The Chained Patriot has arrived.
