Haruo Kaji

Weaving two storylines together: the first is the story of 18th-century shogunate intrigue and loyalty, and the second is a ghost story about a beautiful woman who falls victim to passion and evil.

A young female samurai comes upon a dying messenger and agrees to deliver the scroll he was carrying to its destination. However, unbeknownst to her, the scroll is actually a formula for a new kind of gunpowder. An evil clan that is planning to overthrow the Emperor is also after the scroll, and they try to take it from her.
