the individuals who are complaining about this manga are the usual idiots who complain about anything at the drop of the hat x.O; you know "it's not the way I'd write it so it's not a good manga"
It's great. The MC doesn't only rely on the cheat skills he has and takes his time analyzing the situation he's in instead of the usual junk isekai that is based strictly around the cheat skill and how "uniquely" it can be used. The MC is smart, not afraid to spill blood if he has to, and is not a simp... yeah, he gets a really hot battle slave and, unlike every other MC, actually takes her to bed just as often as you would if you had a slave that sexy. There are definitely borderline hentai scenes (plenty), but it takes a back seat to the story. Those individuals who are complaining about the amount of sex is because the past 3 chapters (41-43) was about his new slave adjusting to their at home life AKA a lot of 3P. Since the chapters release on a monthly, they completely forget the past 40 chapters -.-
