Cesar, a seasoned soldier with a shadowy past, is no stranger to supernatural beings and ghosts—they are merely part of his daily reality. Having once saved the world from a devastating war against dragons—a conflict erased from memory—he returns home only to be caught in yet another war. The Alliance and the Empire have been locked in the relentless Continental War of Europe for years.
During a critical mission to retrieve the Codex—a powerful gem capable of granting a wish at a great cost and the very artifact that sparked the dragon war—Cesar loses his life. However, he is given an unexpected second chance: the opportunity to return, but in the body of a white fox girl. Faced with a familiar face and an even greater mystery, he accepts, driven by the desire to save his sister, reunite with his lost family, and uncover the secrets of his past that continue to haunt him, even beyond death.
