I could forgive the repetition if there was some progress. The problem is that there's almost none until this weird literal numeric value measure pops up to give the writer an easy way to short-hand the improvements without having to show it in the wider story progression.
Adding onto this - even if the overall plot structure of these mini-stories were repeating, we could still use those smaller stories to give details about the world or the characters but instead we get practically nothing. I can only think of one example of each so far: a character detail about the wind spirit princess that she loves to sing and dance but would get embarrassed about it, and a world detail in the form of the exposition dump from the giant whale-like spirit about how spirits essentially have a parental love for humans, and that's why they'll do absolutely anything humans want. Besides those two
(and let's be real they're pretty weak all things considered) we know nothing more about the setting or our lead characters than we did at the start.
Off the top of my head, as some easy examples:
Why do spirits love Univas so much? Is it only because he kinda bothers to talk to them and treat them like sapient creatures? Is it the result of his Spirit Charmer ability (remember that from the very first chapter and how it's never been brought up since?) automatically making him more favorable to spirits? If it's the result of his ability how is that narratively any different than the asshat we meet this chapter with literal chains instead of mental ones?
Why was Univas picked to be on the hero's team in the first place? He obviously wasn't chosen because anyone else in the party liked him, was this a decree from the kingdom? If so, why?
What was the Demon King even doing? What role do they (or other demons for that matter) play in the setting? Are they even still around? Are demons just "evil" spirits, or are they some other entity entirely?
I don't mind a more monster-of-the-week style repetitive storytelling, but the readers should still be getting
something out of each one!
