Emi once believed that heavenly deities were correct and wise, and earthly youkai were bloodthirsty and evil. But the goddess is about to destroy her world, and youkai become the only protection for people. The lies she's been listening to since childhood can no longer hide the horrifying reality. Despite the looming threat, Emi can't escape her greatest distraction: Shiro, the fox youkai who has captured her heart. Soon she will have to break the curse that binds his magic and memories. Once the ancient power awakens within him, the youkai she loves will be changed forever. Earth's deities declare war on the heavens, and Emi and Shiro must risk everything to defeat their immortal, all-powerful enemies. Together they will find a way to save the world, even if it means losing each other.
