Nemuri Kyōshirō (眠 狂四郎, Nemuri Kyōshirō) is a series of jidaigeki novels written by Renzaburō Shibata. The stories were originally serialized beginning in May 1956 in the Shūkan Shinchō. The stories take place during the Edo period under the Tokugawa shogunate and the rules of Tokugawa Ienari and his successor Tokugawa Ieyoshi. They center on the title character, a sleepy-eyed rōnin, or outlaw swordsman, who is the son of a Japanese mother (the daughter of a daimyō, who commits jigaki (see "Female Ritual Suicide" in Seppuku) some time after Kyoshiro's birth) and a foreign father, and who was conceived during a Black Mass (resulting in his fierce hatred for what he considers the hypocrisy of Christianity).
