My Wife Is the Underworld Queen

Alesis has a family that makes life hard for the woman he married. His sister spreads trouble in the house, his mother is carrying on an affair she keeps quiet, and his first love keeps turning up to work on him. What none of them account for is that Renee, who has settled into being a wife and keeping house, is Lady Reaper of the underworld. She slaps the sister-in-law. She gets her hands around the first love's throat. She tells the household about the mother-in-law's affair. Then Alesis walks in and Renee is crying in his arms. He deals with whoever started it. Afterward Renee goes back to her rival on her own and runs through the list of ways she outmatches her, in pull, in skill, in strength, and asks where she found the nerve.
