Sleeping Madness: The Ronin's Blade

During the Bunsei era under Shogun Tokugawa Ienari, a fierce power struggle erupts within the shogunate between senior councilors Mizuno Tadakuni and Mizuno Tadatomo. Amidst this turmoil, a mysterious ronin named Nemuri Kyoshiro (played by Hasegawa Hiroki), bearing the legendary sword Muso Masamune, appears in Edo. Tasked by Tadatomo's confidant, he secretly assassinates a killer, only to find a Christian rosary around the victim's neck. Returning the relic to the assassin's sister, Shizuka, he incurs the wrath of believers and the wealthy merchant Bizenya, who now plot his downfall. Meanwhile, the high official Matsudaira Mizunokami, under Tadakuni's orders, dispatches a master swordsman to hunt Kyoshiro. As political intrigue and faith collide, a complex battle for survival and vengeance unfolds.
