Akuyaku Reijou Gloria von Caldwell no Danzai to Fukushuu @COMIC

Duchess Gloria's life ended in betrayal—framed and killed by her fiancé and her own family. Yet death isn't the end: she awakens as a ten-year-old, the past restored before her eyes. With a chilling smile, she vows to drag her betrayers into hell, starting with her faithless fiancé and her father who traded her for power.
