Baki-Dou: Netflix releases The Invincible Samurai trailer sets up Baki’s deadliest fight yet against legendary swordsman Musashi Miyamoto

Netflix has released the official main trailer for Baki-Dou: The Invincible Samurai, offering the most detailed look yet at the next installment in Keisuke Itagaki’s long-running martial arts franchise. The anime is set to stream worldwide on February 26. The newly released footage confirms a major shift in the series’ signature Underground Arena battles, beginning with an announcement that the long-standing ban on weapons has been lifted.

This change introduces Miyamoto Musashi, the legendary samurai revived through a secret cloning experiment conducted beneath the Tokyo Skytree. The trailer highlights the central conflict of the new arc, pitting modern bare-knuckle fighters against Musashi’s lethal swordsmanship. With live blades now allowed in combat, the series raises the stakes significantly, making defeat potentially fatal for the fighters involved.

Netflix also revealed the anime’s theme songs. The opening theme, “FURUBOKO,” is performed by WANIMA, while the ending theme, “Mountain Top,” is performed by Novel Core. Both tracks are featured in the trailer and underscore the intense tone of the series.


In addition, the streaming platform confirmed an English-language dub featuring Troy Baker and WWE superstar The Miz, signaling a major international push for the release.

What is BAKI-DOU: The Invincible Samurai

BAKI-DOU: The Invincible Samurai picks up after Baki Hanma’s long-awaited showdown with his father, Yujiro Hanma, leaves the underground fighting world in an uneasy calm. With no rivals left to challenge them, Baki and the other elite fighters find themselves searching for a new purpose.

That calm is shattered by a secret project unfolding 364 meters beneath the Tokyo Skytree, where Japan’s legendary swordsman Musashi Miyamoto is brought back to life. His return sets the stage for a new kind of battle, one that pits modern mixed martial artists against an ancient master of the blade.

As seasoned fighters like Doppo Orochi, Jack Hanma, and Kaoru Hanayama prepare to re-enter the arena, Baki once again steps forward, eager to face the ultimate test. The series builds toward a historic confrontation between Baki, the strongest underground fighter, and Musashi Miyamoto, the undefeated samurai, in a high-stakes clash that bridges eras and redefines combat.

The story centers on whether raw modern strength can overcome centuries-honed swordsmanship in a battle that crosses both time and fighting traditions.
