A decade has passed since the conflict between the Iga and Kouga ninja clans concluded. The two factions have ostensibly made peace, supposedly erasing the hostility that once defined their relationship. Hachirou Kouga and Hibiki Iga, heirs to their respective lineages, appear to have ideal circumstances for their romance to flourish, yet not everyone is content with the outcome of the ancient feud. Conflicting accounts of the final confrontation between Gennosuke Kouga and Oboro Iga have circulated, leaving Tadanaga Tokugawa—whom the Kouga served—dissatisfied. As tensions between the clans escalate once more, the simmering political atmosphere threatens to separate the destined lovers, mirroring the fate of the previous generation.
