Nana, a diligent and obedient housekeeper, takes her duties so seriously that she accepts her master's lewd requests as part of her job. When asked to "wash my back," she's made to give a full-body scrub, and when told to "check the condition of my lower body," she's forced to look at his erect penis and even perform sex to confirm it's functioning properly. Her unwavering commitment to following orders is one of her defining traits.
