My Boss Is the Lord of the Netherworld

Following eight hundred years of serving as an austere magistrate in the underworld, an ancient soul awakens in the mortal realm as the neglected heiress of an affluent dynasty. Displaced by an arrogant male impostor and witnessing her birth mother slowly succumbing to poison, she bides her time.

Assuming the guise of a humble household cleaner, she wields a mystical ledger that manifests instantaneous karmic consequences upon wicked deeds. Methodically targeting each conspirator, the undercover arbiter delivers ruthless justice to reclaim her family's honour.
