The day she was abandoned in the canyon, Serna lost everything—her family, her comrades, and even the hands that once held a sword. In the moment when only death remained, what pulled her into an embrace and miraculously saved her was a 'monster with a human face.' Two months later, when Serna awakens, she is greeted only by the ashes of her homeland and the name of the teacher who betrayed her. She must survive. She must reclaim what was lost. She must have her revenge. At the first step of this desperate path, Serna reaches out and grabs the hand of the monster who endlessly offers his to her. He was innocent, dangerous, and a being who offered absolute, pure love only to one person: Serna. 'If that is what you want, I will do it.' 'Tell me, Serna. Tell me you want me.' A path of vengeance walked while harboring a taboo. At the end of it, what awaits her... is it salvation, or ruin?
