Shurannosuke Sakaki is a masterless samurai with a razor-sharp katana and a cold-hearted personality. Whenever you see the mark of two crossed scythes on his back, death is sure to follow. Because of his exceptional swordsmanship, Shurannosuke is hired by the Nakura Clan to rescue Princess Mayu from the Seki Ninja. In this mission, he must use his full potential to survive the Seki Ninja's notorious henchmen.

The year is 1580, and the unholy armies of Lord Nobunaga Oda spread across Japan, murdering all who oppose them. Narrowly escaping the slaughter of her clan, a young ninja steals into the shadows. She is the last of her kind, and the dagger she wields is one of three mystical blades that can end Lord Oda's rule. On her quest to overthrow the tyrant, she is joined by two other renegade ninja, possessors of the sacred sword and spear. Together, these shadow warriors must unite their weapons and skills to fulfill the Prophesy of the Enchanted Swords... or die trying.
