Kurozuka

In feudal Japan, Kurou and his servant Benkei are on the run from Kurou's older brother, who has just taken the throne. While escaping through the forest, they stumble upon a house where a mysterious woman named Kuromitsu offers them shelter-but only if they stay out of the inner rooms. Before long, the Red Army attacks, hunting Kuromitsu for her blood, which grants immortality. Mortally wounded, Kurou drinks some of Kuromitsu's blood and gains immortality along with bizarre powers. But soon after, he is seemingly beheaded-only to awaken centuries later in a ruined city. In this warped future, the Red Army dominates everything, still desperate to claim Kuromitsu's blood, while a rebel faction fights to stop them. Surrounded by danger and driven by his obsession, Kurou sets out to find Kuromitsu and take revenge on the Red Army.
