While the opening was a clear 10/10 when compared to most isekai, the later development in my eyes took a huge dump on the foundation laid out in the first arc.

I read up to mid-way trough the second volume and I might pick it up again in the future to see if it somehow raises back up from it's ashes.


Spoilers:
The first arc, that is the childhood arc has a wonderful and emotional buildup that also clearly sets the main character on his path. It has great character development, making the unavoidable sacrifices all the more sad. Besides that, I also liked how it tackled the question of "immortality vs experiencing life", ending with MCs conclusion that stagnation (immortality) will remove the feelings people come to enjoy troughout their life spans - to put it shortly.

After the character sets out on his journey however, I felt that the story took a turn for much worse. From great and in-depth character developments when the cast was limited, it changed into a story of a much more mainstream OP MC that everyone praises, and just him shining his light of awesomeness was enough to make him do cool sh*t. He basically starts getting rid of all the problems with his already earned powers and doesn't get much development in that regard. There are some attempts at character building, but they end up feeling worthless (the "I can do everything alone!" "No u can't" "Oh okay" part). William's first contact with another person ends up being his longest, as the half-elf he meets becomes pretty much his closest companion. Besides that, on the same day he arrives in the city and after hearing a story of his guardian's past deeds (namely killing a Wyvern as an adventuring trio), he just straight up kills a wyvern himself. Soon after he's given a title of Paladin because of how awesome he is in pretty much anything anyone can be when it comes to fighting and is granted a territory. Which btw, at least in my understanding, is almost neighboring the area he grew up at, so he basically didn't journey far. The rest of what I read can be summed up with pretty much "he kills stuff, people say he's cool, dwarves think he's especially cool, there's some quickly inserted companion powerup, and some tease for when he would get a sh*t load of money just because he'd say "Augustus" to some half-elf old lady".

Once again, awesome opening, terrible later execution. Sorry if it came out a bit ranty, but I just remembered all this when I was removing it from my long not visited favorites lol.
This review might change after I read further into the series, but honestly the first 1.5volumes already turned me off, and I'm not the kind of person to go with "after 2 shit seasons it's pretty good, so give it a try".
