With the power of the shogunate, Ieyasu, the supreme ruler of Japan, holds sway over the Sengoku Era. Those who refuse to follow his whims are doomed to be put to death by the god of war, Kibitsuhiko-no-Mikoto. But behold! Seven shadows are still rampant in this ruthless world. Are they men? Beasts? Petals? The wind? No, they are the seven blades of the Efu–the grudgeful ninja! Note: The Efu were the personal guards of the Emperor of Japan and his palace before the Feudal Era, following the establishment of Ritsuryō.
