When tyranny grips the kingdom following the Holy Knights' coup, a princess ventures into a world shrouded in darkness to find those labeled as traitors. The Seven Deadly Sins were meant to be legends of the past, yet she discovers they might be far more alive than anyone believes—and perhaps far more righteous than history claims. What begins as a desperate search for allies becomes a profound reckoning with truth, redemption, and the cost of reclaiming what was lost.
