Kurozuka

In feudal Japan, Kurou and his servant Benkei are on the run from Kurou's older brother, who has just taken the throne. In a forest, they find a house and a mysterious woman named Kuromitsu, who agrees to hide them on one condition: they must not look into the inner rooms. Soon after, the Red Army attacks; they are looking for Kuromitsu, whose blood grants immortality. Fatally wounded, Kurou drinks some of Kuromitsu's blood and becomes immortal, gaining strange powers as well. But shortly after, Kurou is seemingly beheaded and wakes up centuries later in a ruined city. In this twisted future, the Red Army is everywhere and still hunting for Kuromitsu's blood, while a rebel army tries to stop them from getting it. With danger at every turn and driven by his obsession, Kurou sets out to find Kuromitsu and take his revenge on the Red Army.
