It's Valentine's Day night but, instead of celebrating, the world is dead. The powerful and cruel demon Sinfan lands on the only isle left to explore, in the hope of finding someone to drink from and to infect with madness toxin. He is tired and starts being delirious, like a simple mortal. He doesn't conceive yet that destruction is a revenge of love and that someone is waiting for him in the dim light of the dying moon.
Who lured him to that haunted forest? A woman? A man? Or another demon from his daunting sect?
