Witness a soul's rebirth. Heather begins his search for the truth in the darkest of places when he promises his soul to the seemingly benign demon Vincint in a desperate attempt for survival. A blind boy with only the demon's voice to guide him, Heather struggles to find meaning in a harsh world where the nobility's rule is absolute and the masses are oppressed. Haunted by the memory of his mother's attempt to kill him and the sudden loss of his family and noble status, Heather embarks on a new path on which he gains and loses more than he could ever have imagined. Through experiences of betrayal, abuse, and death, he finds friendship in a world where love is scarce and invites his fate through the enchanted violin songs of Vincint, who ultimately will condemn and save Heather's broken soul.
