Baki-dou

After the long conflict between Baki Hanma and his father Yuujirou finally settles, the world's strongest fighters face an unexpected problem: boredom. No challenger in the underground arena gives Baki the danger he craves, until a scientific project successfully clones and revives one of Japan's most legendary warriors, Miyamoto Musashi.

Musashi awakens with the values of an era in which a duel genuinely ended in death, and he sees little reason to treat modern combat as a safe sport. He begins testing himself against Doppo, Katsumi, and the other fighters of Tokyo, turning each match into a collision of philosophies as much as skill. Baki finally finds an opponent capable of ending his boredom, but the excitement he wanted arrives with a sword that has no interest in the limits the 21st century places on a fight.
