In the year 1580, as a comet streaks across the sky and a dark god awakens, ancient evils emerge from the depths of Hell to plague the world. Amidst the chaos of Lord Nobunaga Oda's conquests in Japan, a lone ninja, Ayame, survives the massacre of her clan. Armed with a mystical dagger, she joins forces with two other renegade ninjas, Sakon and Ryoma, each wielding their own enchanted blade. Together, they must combine their weapons and skills to fulfill the prophecy of the enchanted swords or face certain doom. This tale unfolds in the shadowy realm of warriors, where alliances are forged, and destinies are entwined, in a battle against darkness. This narrative is a condensed adaptation from the original OVA series.
