Feudal Japan is set to bear witness to the bloody clash of titans as two fearsome ninja tribes are unleashed, one upon the other. For wretched within the Edo Castle loyalties have been severed into warring factions, as two sons struggle to inherit the title of Shogun. If this rupture goes unresolved, the Tokugawa kingdom will be torn apart. A solution must be found, one befitting a samurai family. The Kouga and the Iga, two ninja clans with four hundred years of hostilities between them, meet at the request of Lord Ieyasu. There they learn that the peace forced upon them is to be broken by the whim of royalty, and that the outcome of this battle will determine the next Shogun. The passions of the past quickly reignite as two scrolls are sent out into the night. Ill-fated is this event indeed, for lovers stand with hands entwined as travesty approaches on the wings of a hawk. Reared from birth as sworn enemies, Gennosuke and Oboro, each the heir of these rival clans, seek lasting peace between their peoples. But the terms have been set, and two lists seal their destinies. Two lists from which a name can only be crossed out in blood. No mercy will be spared to the enemy.
