In my honest opinion, this manga is a shitshow. No, not the story itself. The story is perfect, but the manga itself is a shitshow. As I understand, this is a manga adaptation of a web novel, and from what I understand the web novel is actually good, but this """"adaptation"""" is not.
To be frank, I wouldn't even want to call this an adaptation, because it seems more like a fan fiction than anything else. Any important information, story, or context that is pivotal to the entire fucking story is literally never even mentioned here.
I am approaching this manga as-is, without having ever read the WN, and perhaps this is the reason why I fail to understand many important plot points, but a manga should never require you to read its source material in order for you to understand it. Perhaps that's why this manga ended so abruptly, because it was so hard for people who have never seen the story before to pick up the manga, which caused it to fail in the market and to get axed.
It's such a great story and the art is amazing and interesting, but seeing a character make a troubled face and going "oh boy what important information have I missed this time" made the experience so... tiring. For example, in the WN, a wizard comes and explains why their house still has running gas and water, but the manga has fuckall to explain in that department. You only hear a character briefly mention something like "We still have running water but I don't know why" halfway through the manga and it doesn't even elaborate further. In fact, the pacing of the story and how fast things happen and characters are introduced makes it feel like the author of this was trying to rush through everything and just get the end, or something.
I don't know, this manga is weird. If you want something to just mindlessly read through that has some fun characters, go ahead, but just make sure to turn your brain off before you do so.
