I came across this manga while looking for more isekai trash to read, but seems to me that the isekai aspect of the story is completely inconsequential. Author probably only added it in there anyway since isekai stories are popular. I don't read the novels though, so I could be wrong. Regardless, this work has me looking forward to the next chapter. Art is quite decent but I've seen better. Art style kinda reminds me of Koe no Katachi (which I really appreciate). Pacing is a preference for most, but I like how the story is taking its time to establish the characters and the world. I feel like it's skimming over some details, but it tells you just enough to have some grasp of what the world is like. Overall, pretty enjoyable. Hoping for an epic adventure when Will finally embarks on his journey (or is this not that kind of story? lol) and some character development, too, please.
As an aside, I find babies having the awareness and mentality of an adult creepy. It reminds me of the end credits to Welcome to the NHK.
