Wrapped in soft white fur, crowned with a fluffy neck, and sporting an impossibly bushy tail—Milfiria is an absolutely adorable fox cub with an extraordinary secret: she's the reincarnated soul of a Japanese girl. Tasked with guarding her home while her mother journeys to the capital, the lonely little furball soon finds the separation unbearable. Driven by yearning, Milfiria abandons her post to chase after her mother, only to become hopelessly lost within the Northern Fort—a fortress protected by powerful knights.
