Demon Princess Returns

An orphan rises to become an infamous figure, known as the "demon girl." When her long-lost billionaire parents finally find her, she's in the middle of dealing with criminals. Playing the obedient daughter, she returns home—only to find her "wealthy" family dressed in rags. Turns out, her love-blind sister has drained the family fortune. No worries. With her around? They took from me? They'll give it back.
