In the twilight of a fractured empire, where warlords grasp for power and the shadows teem with secrets, Ayanami—a gifted kunoichi trained by a dying order—receives a final mission: infiltrate the court of a rising daimyō and retrieve a legendary artifact said to bend the will of men.
But when Ayanami uncovers a conspiracy that threatens to plunge the entire nation into darkness, she must choose between loyalty to her clan and forging her own path. Torn by duty, haunted by a tragic past, and pursued by both allies and enemies, she becomes the spark in a firestorm that could remake the land.
The deeper she dives into the web of politics, betrayal, and forbidden power, the more she realizes: the most dangerous weapon isn't a blade—it’s a secret.
