Demon Eyes Kyo



Demon Eyes Kyo

Kyo is the other personality in Kyoshiro's body. His mission is to find his body and to kill Mibu Kyoshiro. Kyo has red eyes, one of the original Muramasas and is known for killing 1000 men at the Battle of Sekigahora.




Apparently a man from another time period, Migeira hopes to unite the 5 real Muramasas to restore the world to its true form.



Mibu Kyoshiro

The orign of Mibu Kyoshiro remains a mystery throughout a good portion of the series, but he and Kyo appear to share the same body. Kyoshiro and Kyo have completely separate personalities and fight for control during the first couple episodes until Kyo emerges fully. Kyo has vowed several times to kill Mibu Kyoshiro.


Okuni

A mysterious woman who's loyalties are not yet known, although she seems to be incredibly powerful. She also knows of both Kyo and Kyoshiro and seems to have a history with them that Kyo doesn't quite remember.





Sakuya

Sakuya is apparently a very powerful woman, who has won the loyalties of many people including Yukimura. She had something to do with the outcome of the Battle of Sekigahora and the appearance of Demon Eyes Kyo.



Sarutobi Sasuke

One of Yukimura's loyal samurai and companions. Because he grew up in the forest, he was feared by society. Yukimura embraced him when he was still young, and since, he has become known as the most powerful shinobi among the Sanada vassals.



Shiina Yuya

Yuya is a bounty hunter who is seeking a man with a cross scar on his back. That man killed her brother. She follows Kyo because he seems to know something about the event



Tokugawa Hidetada

AKA Benitore and Red Tiger through the series, Hidetada is the future shogun who will succeed Ieyasu. He is fighting both to rid his land of Kenyou and because he has fallen in love with Yuya (who has no idea who he is).



Yukimura Sanada

Known as a wise general in the Warring States era, Yukimura fought with his father in the Western Army while his brother joined the Eastern Army led by Tokugawa Ieyasu during Sekigahara. Now his intentions are unknown, although he seems to want Ieyasu dead. Kyo entertains him, and the two work together several times during the series, although his main loyalties appear to be with Sakuya.
