After winning a brutal underground tournament, Baki Hanma continues his quest to defeat his father, Yuujirou, the world's strongest man. However, he gets no time to rest when the tournament organizer, Tokugawa Mitsunari, visits him at school. He reveals to Baki that five incredibly dangerous death row inmates from around the world—all skilled in martial arts—have simultaneously escaped confinement and are heading to Tokyo, each wishing to finally know the taste of defeat. Tokugawa warns that, due to his well-known strength, Baki is bound to encounter them sooner or later, and he will not be their only target. Adapting the first saga of the second manga series, Baki centers on the all-out war between the esteemed martial artists of Japan and those of the dark underground world.
