Just as he is accepted into a prestigious academy in a distant Empire, he is tragically killed by a mystical beast on his journey there. In his final moments, he desperately prays to the stars, and his plea is answered by a mysterious being named K. To return to the mortal realm, Davis must sign a contract with this enigmatic figure to extend his life. Guided by K, Davis resumes his quest to become the strongest magician on the continent.

Alongside new companions, Davis uncovers a startling truth: gods and celestial beings from a forgotten war have been resurrected in his world, now wandering both its light and darkness.
