Endless winter.
Since the huge conflict between the Hunter Association and vampires, the world has fallen into an endless winter.
The resurrection, war, death, and dormancy of pure-blood vampires caused drastic changes in the climate, causing cold winds and snow to rage, which is the so-called Ice Age.
After the conflict, humans and vampires struggled to find a way to coexist in a harsh environment. Five years passed peacefully.
In a world of pure white snow, there is an unknown future, slowly blooming like a bloody rose in the endless winter.
