First of all, I have to say something: this is a twisted manga. I’m not saying it isn’t funny at times, but it’s a real shock when, after just a few chapters, you see the master doing strange things to his slaves out of the blue. I feel like the slaves aren’t being paid enough to handle their master’s demands... Still, it’s a manga that, even though it’s often weird, manages to make you smile at the situations that arise when the slaves realize their master is a lustful good-for-nothing. I feel like this manga could have been better with a different kind of master(maybe one who’s less perverted and useless), but we respect the authors’ ideas. The slaves’ actions and attitudes seem quite consistent to me, and that’s what makes it pretty funny in an isekai world. There’s a romance story behind it, but it’s not too complex either. I’d give it a 6 because at least it made me laugh, but I wouldn’t know if I should recommend it because of the protagonist’s perversion.
