Devotion of Sin follows the story of Erica, a young devotee whose whispered prayer resurrects Azarel, a pagan god long cast into shadow. What begins as fear turns into obsession, as her body, blood, and soul are bound to him in rituals of worship and ruin. Their bond grows darker and more consuming, pulling her past innocence into eternal possession. It is a tale of forbidden worship, sensual darkness, and devotion that defies heaven and earth.
