The clans follow separate paths to Sunpu Castle, as Gennosuke seeks the solution to the riddle, this costly ninja war. But treachery and death follow hard at their heels, as those blinded by hatred long harbored seeks to shorten their lists. Oboro, convinced death shall be delivered by love's own hands, has become a prisoner within her own clan. The past weighs far too heavy on the present, and the path to carnage is one that cannot be escaped, once begun. No mercy will be spared to the enemy.
