A former corporate slave who died from overwork is reborn as a villainous noble lady and plans to live a leisurely life as a decorative "figurehead owner" who doesn't work at a black-market guild in a remote frontier. However, for some reason, her subordinates revere her as an ice-cold charismatic supreme ruler.

"Eleonora! I'm breaking off my engagement with a 'zero' like you! Go to the frontier blackguild and drop dead!" Duchess Eleonora was abandoned by the prince who was obsessed with the state-appointed holy maiden, and was also disowned by her family. However, she was overjoyed. This was because her past life was a Japanese corporate slave who died from overwork with over 200 hours of overtime per month, and she desired nothing more than to be freed from the black labor of royal consort education! "Thank you for exiling me abroad! Now I can finally go home on time!" The frontier guild she was demoted to was an ultra-black workplace with endless sleepless nights due to monster attacks, but she enforced "no overtime" and "mandatory going home" for her own good sleep. Then—— "Wait, the monsters disappeared just by turning off the lights and sleeping? (※I just used my gaming knowledge)" "The mud I thought was garbage and threw away sold for a high price? (※It's a hidden item)" Even though she only wanted to slack off, her actions were all misunderstood as "profound consideration," and before long she was being revered by the rough men as a "cold-blooded charisma." Before she knew it, the rundown guild had transformed into "the continent's strongest white organization" with high salaries and complete benefits. Meanwhile, the kingdom that had exiled her, an excellent administrator, found itself unable to process paperwork and faced rapid collapse. The desperate princes came crying, "Please come back," but Eleonora sipped her tea elegantly and declared: "Rejected. Your workplace is far too black. Now disappear from my sight forever." This is the story of a former corporate slave villainess who intended to live a life of laziness at the frontier, but instead became the strongest ruler, causing her former fiancés to meet their comeuppance both physically and socially.
