Teisou Gyakuten Isekai de Sukebe na Bijo-tachi ni Kakomare nagara Boukensha Seikatsu

Akira Kusaba’s life takes an unexpected turn when he is summoned to the otherworldly realm of Rumisia by Lucia, a striking silver-haired woman. Rather than being tasked with saving the world from impending doom, Akira discovers his true purpose is far more mundane: he has been brought over simply to help Lucia earn money. Exhausted and bewildered by this bizarre arrangement, he reluctantly begins working part-time jobs in this unfamiliar land. However, as he settles into his daily routine, he slowly realizes that something about this world is fundamentally different from his own. Everywhere he looks, Akira encounters situations that defy common sense. He crosses paths with a female adventurer who casually requests that a man wipe her breasts, and faces slimes specifically driven to drain the vitality of men. Even Lucia, his summoner, insists that he sleep beside her, secretly indulging in intimate acts right next to him in bed. It soon dawns on Akira that Rumisia operates under a radically altered set of social norms—a reality where the traditional concepts of chastity between men and women have been completely reversed, leaving him constantly surrounded by dangerously alluring women throughout his new adventuring life.
