Vampires really exist, and so do hunters.
Cain and the world's first vampire hunter disappeared from this world together, and the conflict between humans and vampires seemed to end there.
The remaining vampires put away their fangs and began trying to blend into human society.
They educated their descendants at their own academy and lived out their long lives.
But one day, the hunters began hunting vampires again. With no other choice, the vampires attacked them.
There is no undoing the deaths. Blood that has been spilled can never return to the bodies it left behind.
To win the right to stand in the light, war broke out for a second time...
