As Professor John accepts Sabuko's arcane methods against scientific reasoning, Hanayama gears up for an all-out fistfight with Yujiro on Tokyo's streets.

After facing Japan's greatest modern swordsman, the peerless Musashi Miyamoto demands the most skilled fighters in the country. Baki steps forward.

Baki unleashes his fastest strike — but the samurai is faster. Later, as Musashi roams the city, his actions catch the attention of other martial artists.

The first to move is Doppo Orochi. After a brief tussle, he asks Musashi to use a real blade. How will God's Hand fare against the sword saint's steel?

The deathmatch between Retsu and Musashi comes to a devastatingly brutal conclusion. Baki visits Izo Motobe for guidance and flies into a rage.

After defeating Japan's kendo champ, Musashi faces jujutsu master Goki Shibukawa, who greets the samurai with a firm handshake — and a punch to the face.

The strongest being on Earth clashes with the strongest samurai in history at the Tokugawa estate! Yujiro demands Musashi face him with two swords.

Jack Hammer arrives at the Tokugawa estate hoping to fight Musashi, but first must defeat Motobe, who's determined to be the next to take on the samurai.

To prevent further chaos, Pickle is sedated and brought to the Skytree lab. Musashi shocks everyone by slapping the prehistoric man in the face.

Tokugawa reunites Musashi with his legendary blade and meets with a resolute Motobe. Meanwhile, Pickle starves himself for the upcoming match.

The Sengoku era's strongest swordsman clashes with the Cretaceous' mightiest warrior — but what happens when Pickle himself takes up a sword?

At last, Motobe sees the culmination of his years of training. He throws every trick from the Sengoku period at Musashi to protect his comrades.

After Musashi "slashes" the host on national TV, the Japanese police move to apprehend him. The samurai leaves the Tokugawa mansion and begins a rampage.

The bloodbath continues as Musashi cuts through a platoon of the police's elite. Meanwhile, the President of the USA prepares for a meeting with Yujiro.

Musashi continues to resist, leaving a mountain of bodies in his wake. Later, Police Commissioner Utsumi asks one unlikely person to fight for the nation.

In Shinjuku, Hanayama stares into endless darkness and takes his signature stance. As he swings, Musashi seems blinded by his pure fighting spirit...

Punching, pinning, crushing — Hanayama throws everything he has at Musashi. But can his iron muscles withstand every cut, slice and rip Musashi inflicts?

Baki resolves to eradicate the samurai from this world and hones his body at a dojo. Meanwhile, Musashi prepares for the match with a visit to the sewers.

The day of the showdown arrives. Before this once-in-a-lifetime match begins, an unimaginable sight unfolds before Musashi. Baki is ready to let loose.

Musashi retaliates brutally, proving that even barehanded, he is unmatched under heaven. But Baki will not back down until he buries the samurai.
