Isekai doesn't need more of: Rape, Slavery, Grooming of potential baby hosts (the past three all tend to go hand in hand!), seemingly effortless power acquirement (it makes the story boring), tension-less resolution of problems without ever encountering any real threats (I guess this series might handle that better later, but again- this makes for lazy and uninteresting writing). Within the first 10 chapters of the series I've seen all these things, except slavery (which from browsing through, seems to come later!).
If this is the base of all modern isekai, we can do much much better. Heck, we have much better (or at least different), see series like Saihate no Paladin, Beware of the Villainess!, Isekai Ojisan, and Gate. Even Tensei Shitara Slime Datta Ken, Tsuki ga Michibiku Isekai Douchuu, Shield Hero, and Kumo Desu ga, Nani ka?, which are still guilty of some of the tropes, handle it better. For that matter, wouldn't something like El-Hazard, Rayearth, .Hack, or Spirited Away be among the first isekais- or even just for isekai tensei, Zero no Tsukaima?
I want to like the isekai genre, it has a lot of potential, but series like this are just not good and far outnumber the ones that feel like the writer actually tried instead of carbon copying all this other derivative junk.
