Fourteen-year-old shapeshifting ninja Kitsune is still reeling from the Second Battle of Sendai Castle, but she has no time to rest. Preying on the chaos, the infamous crime syndicate, the Yakuza, has begun kidnapping Sendai City residents and selling them into slavery. Now it's up to Kitsune, her best friend Momo, and the mysterious northern ninja Hebi to stop the operation.
The odds are against them. The slavers are led by Kujiro, a notorious pirate with devastating power. Kujiro's already killed two ninjas, and he plans to add Kitsune and her team to his list. When Kujiro takes Kitsune prisoner, it will take all her strength, cunning, and willpower to survive.
But survival isn't good enough for a ninja. The mission comes first. And to complete her mission, Kitsune may have to sacrifice her friends.
