A long time ago
It is said that there is a sun in the sky
That day, darkness came
People huddled in lonely villages, watching for the arrival of dawn
The boundless night and wilderness
Vampires, undead and demonized creatures
Marching forward
Endless snow forest
Footsteps as fast as raindrops
Pale face, eyes as dark as the abyss
He said, you, I will chase you all my life
The opposition between light and darkness, the choice of fate
A love of betrayal and pursuit
Brave, independent and unyielding exorcist heroine × affectionate, tolerant, contradictory and complex vampire hero
