Emi has dedicated her entire life to becoming the ideal vessel for the goddess Amaterasu, but everything changes when the treacherous betrayal of another deity changes everything. Now Amaterasu has entrusted Emi with an urgent task: to find and free the earth's deities before humanity falls to its knees before an all-powerful tyranny. Next to her is Shiro, the mysterious fox spirit. When Amy first saved his life, she had no idea that behind his guile and confidence he was hiding a confusion - his powers were bound by a destructive curse, and his memories were lost. The spirit's mysterious history is somehow connected to the missing gods, but he doesn't remember how or why. As their search leads them into the misty depths of the spirit realm, shadows of Shiro's past begin to reveal themselves. With each brief awakening of his true nature, Amy loses him little by little. The fate of heaven and earth lies in her mortal hands, and she must find the missing gods before her world—and Shiro's—runs out.
