After his battle with Saishi, Akira collapses! Bontenmaru can carry him through the Second Gate, but there they must choose between two doors... Meanwhile, Izumo-no-Okuni searches for the same mysterious jewel that Kyo seeks. But then she runs into Taihaku of the Five Stars, who makes her an offer she can't refuse...

Kyoshiro Mibu
A traveling medicine peddler, Kyoshiro Mibu is peaceful, lighthearted, and a bit of a coward. He carries a 5 shaku long sword with him, but claims it's just for show. Unbeknownst to anyone, he holds within him the spirit of Demon Eyes Kyo, and when provoked, the red-eyed samurai takes over Kyoshiro's body.

Demon Eyes Kyo
Kyo is the other personality in Kyoshiro's body. Kyo, one of the original Muramasas, has blood red eyes and is said to have killed 1000 men at the Battle of Sekigahara. There's a legendary one million ryo bounty on his head.

Yuya Shiina
Yuya is a clever and beautiful bounty hunter, the best anywhere on Tokaido-chu. She seeks a man with a scar on his back - the man who killed her brother. After discovering the secret of Kyoshiro and Kyo, she hopes to unravel their mystery (and possibly to collect on their bounty).

Izumono Okuni
A mysterious and powerful woman, Okuni is a former priestess of the Izumo temple who claims to have been Kyo's lover.

Jiban
A samurai who was shamed by Kyo at Sekigahara. He took a job as a yojimbo to a local Daikan in order to perfect his killing technique. Now he's ready to face Kyo again and regain his honor.
