Does loving someone to the extreme turn you into a demon or a Buddha?
When the horns of the ancient battlefield sound once more, and love and hatred sealed away for ten thousand years awaken anew, a swordsman bound by fate and a cursed witch write a battle hymn of love and hate with their mortal bodies beneath the vast heavens.
This is no simple clash between good and evil. It is a struggle of human nature between love and hate, life and death, forgetting and remembrance. Behind those mighty martial arts techniques lie the deepest softness and strength of the human heart.
