A half-vampire since birth, Eve's life is very "simple": hunted by purebloods, wanted by the church, and her diet is disgusting monsters. Until she bumped into the man who was investigating the massacre—Ciel, the last demon-hunting noble.
When the conspiracy to exterminate the family, the black hands of the church, and the fallen angels who use the human world as a chessboard came at them at the same time, they found that they were destined to die alone.
So, the two people abandoned by the world made the most rebellious contract in the world:
He offered his reason and flesh to protect her from the sun and the silver blade. She handed over her back and fangs and became his living weapon to tear apart the darkness.
—They had agreed. Little did they know that this road of eternal night, which begins with use and betrayal, ends with the light of mutual martyrdom.
