Kuro's true form makes him an outcast — and a deadly weapon.

Left for dead by his own mother, Kuro survived and grew up only by hiding the color of his fur. Society has been trained to fear — and kill on sight — foxes like him.

When Ren stumbles into him trying to destroy the demons plaguing his kingdom, Kuro fears the end. Instead, the human boy proves himself a loyal friend.

But when Kuro's secret slips out, the Shogun sees only the weapon he needs to vanquish his enemies, including Ren. Now Kuro's chance at survival comes at the price of his only friend's life.
