Celica Sylphil, the immortal warrior known as the Godslayer, lives within the stolen body of the goddess Astraea. For this, he is hunted day in and day out; servants of the gods seek to kill him for the threat he poses, while demons seek to take the power of Astraea's body for themselves. Only the matron goddess of the kingdom of Rewinia offers him sanctuary; alongside the White Dragon Knights and their commander, General Revia, he fights to hold back the forces that would do the kingdom harm.
