I read all of the light novels, watched the anime twice and completed the manga so far. I am confident in my assessment that this is a dead or dying series.
There are a few reasons for this. I will list them in order of magnitude from the most cancerous to least.
First of all, while it is obviously easy to write about illiterate adventurers chatting idly in a tavern, it should go without saying that your readers do not want to see that shit.
Secondly, while it is obviously difficult to write characters who are smarter than you, it should go without saying that you can't just write about literal children playing house for entire chapters. You also can't completely omit all of the interesting activity being done by the guardians except to make mention of it that it's been done already. We had those great chapters following Sebas and penetrating into his psyche, those were some tense chapters. I really wanted to know what would happen next. Why is Sebas the only guardian who gets a side story?
Lastly, the total exclusion of meta is astonishing. Is the author actually afraid to explore anything meta? Why would you take such an interesting premise and overworld and write a slice of life? I feel like Fluder when Ainz took back his magic glasses, reading this. Fucking love this series despite all of that. It's good escapism, I find myself imagining what the guardians are up to and whether a super milky succubus mommy girlfriend will ever say ara ara to me.
