Samurai Deeper Kyo [Manga]
Set in Tokugawa Japan, this manga begins by following Shiina Yuya, a bounty hunter searching for her brother’s murderer. However, Yuya quickly meets a medicine peddler named Mibu Kyoshiro, who turns out to be sharing a body with the feared samurai Demon Eyes Kyo. Over time, Mibu Kyoshiro and, to a lesser extent, Shiina Yuya recede from the story while Demon Eyes Kyo comes to the fore. Kyo’s only stated wish is to regain his own body. Following this path leads Kyo, Yuya and a variety of fellow travelers into conflict with both the Tokugawa shogunate and the Mibu tribe, a race of violent superhumans who have run Japan from the shadows for millennia.
