The score alone is enough to make you feel unsettled and looking behind your back for a sly Koga Ninja! A clan is doomed, ninja are the problem, and expendable mercenaries are hired in a desperate gamble for survival. Enter Wadakuro, a down-and-out ronin played with Deniro-like ferocity by the legendary Jushiro Konoe. Is he fighting for the clan's protection, or his own vengeful obsession to slaughter everyone in a black hood? And will anyone survive the bloodletting that unfolds? The Gamo clan hire Wadakura, Shinzo, Hachi and Yajiro to protect their clan from the Koga ninja and their Shogunate masters. As the Gamo clan daimyo nears death, the Shogunate sends a letter to allow a legitimate heir to succeed him. The shogunate, however, also sends their ninjas to destroy the proclamation to allow them to abolish the clan. The four ninja hunters, who once belonged to clans that suffered similar fates, will stop at nothing to get revenge on the Koga and their leader, Yami-no-Kurando.
