Plot
In a world where dragons are considered humanity's greatest adversaries, two ways exist to bring them down: freezing their blood with silverine, a rare aura granted by silver-infused weapons, or incinerating their bodies with the intense power of sunlight.Leonica, a gifted young hunter, is skilled beyond her years, her strength and prowess unmatched. By her side is Ragna, a seemingly unremarkable companion who struggles to prove his worth. Often mocked by others, Ragna is branded as cursed, for dragons seem drawn to him, slaughtering those close to him in their wake. Yet Leonica sees something in him—potential that others overlook—and she chooses to partner with him on her dangerous hunts.
Ragna, deeply aware of his own lack of talent, places his trust in Leonica's abilities, convinced that she is immune to the misfortune that plagues him. But his world is shaken when he dreams of Leonica's death. Haunted by the dream, he fears it is a prophecy he must prevent. As the fated day approaches, Ragna encounters a mysterious figure from his future—his future self. This enigmatic version of Ragna grants him immense power and the memories of what is to come, preparing him to protect Leonica at any cost.
To fulfill his mission and avert the prophecy, Ragna must seek the aid of a shadowy figure known only as Crimson. Together, they will fight to rid the world of dragons once and for all, facing impossible odds and unraveling a dark history that binds their fates. The journey ahead will challenge Ragna's beliefs, his strength, and ultimately, his loyalty to those he holds dear.
