Two lovers torn apart by clan war get a second chance at life, but redemption in this world costs blood. Hanzo's son pulls them back from the dead, and the show lets you feel the weight of that mercy, it's not salvation, it's a debt that demands payment in the only currency ninja clans understand. Every fight is a reminder that love and loyalty can't exist in the same space, and the show breaks that truth across 24 episodes without flinching.

Two children born from rival ninja clans carry the weight of their parents' tragic past. Kouga Hachirou and Iga Hibiki are the offspring of a Kouga man and an Iga woman whose love was torn apart during a brutal ninja battle over the shogun's succession. Ten years after that war, the Kouga and Iga live in peace, and the two heirs seem well placed for romance. Yet ninja are fading from a land that no longer needs them, and conflicting accounts of the final duel between Gennosuke Kouga and Oboro Iga have left Tadanaga Tokugawa unhappy with the outcome. As tension between the clans grows again, political pressure threatens to separate Hachirou and Hibiki just as it separated their parents. The result is an action fantasy drama about whether a new generation can escape the fate of the one before it.
