I think the original idea of the author was just of a good Overlord MC isekai, the premise is that,it have many cliches at the start of the story that you can find in a thousand other novels but then then it turns better.
In the latest chapter there is a problem in the plot because they wanted to be done with this arc too fast.
The hydra reached the town inthe novel and fought Ifrit there, short fight and all, Ifrit wins anyway but the church of the main human religion gets damaged.
That get mentioned a few chapters later with the townspeople talking about a local legend about a beast of fire that was a protector for their ancestor or something similar and the church getting damaged was a sign that their old teachings were the right ones.
It was the starting point for the city leaving the religion that hates elves and beastmens (for a certain reason, of course bad),it was never mentioned again in the novels, possibly aroute the author wanted to use or hinting that the church position was fragile in some places.
