Fans of the Baki franchise will soon delve deeper into the legend of Miyamoto Musashi with a new prequel series, set to premiere in Spring 2026. This upcoming ONA, animated by TMS Entertainment, will explore events preceding Baki-dou: The Invincible Samurai Part 2, offering context for the legendary samurai's eventual confrontation.

The series adapts the Baki-dou manga, which itself follows the resurrected Musashi as he encounters the modern-day martial arts world. While Part 2 continues this narrative, the new prequel promises to shed light on Musashi's own era, expanding the lore of the formidable warrior before his reawakening.
