Munefusa's father was murdered when he was a young child. And so with young Munefusa in tow, the loyal servant Jindayu sought refuge at Mt. Kurama to engage the child in martial arts training. Twenty years hence, in his dying words, Jindayu reveals to Munefusa that his uncle Muneyuki was behind the murder of his father. Now, after having recently arrived in Kyoto, Munefusa visits Muneyuki and suddenly finds himself saved by his daughter Shiragiku from a murder plot in the night orchestrated by his uncle. Afterwards, Munefusa saves Katsura Kogoro, a leader of a faction opposed to the Tokugawa shogunate who had been pursued by the Shinsengumi special police force in Kyoto. Together with Katsura, Munefusa heads to his father's former villa which is said to be haunted by a masked demon.
