This is a textbook example of how pacing problems can ruin an otherwise interesting story. The first few volumes take it slower, easing you into the world and it's setting. And if this was a 10 volume, or even a 9 volume manga this pace would be how the entire thing goes, ramping up the stakes with each fight, giving a chapter or so of downtime for us to relax, you know, things you expect from a competently structured and paced stories. Instead this is a 7 volume manga, and that requires the pace to pick up a frankly ludicrous degree. The ending few volumes is onefight after another with none of them lasting very long, multiple cliff-hangers being solved weirdly quickly and the ending fight having to basically contort itself to being resolved fast enough for the volume and thus the series to end on time.

And honestly, it's massively to it's detriment. When it takes it's time the character writing really shines through, you get clear moments of moral ambiguity, what it means to be powerful, flashbacks showing how people have suffered and what it means that they're now being accepted as family by the MC. There's a lot of really interesting lore shown regarding gods and dragons and the backstory of the entire world.

And then it all just gets thrown to the wayside for a series of uninteresting combat segments that you know the MC will claim victory in. So why not up the stakes by removing a couple of them and having one or two big tense scenes as opposed to many smaller un-tense ones? Or if you're locked into the 7 volume limit then don't add in all the extra stuff and ruin your pacing, but instead focus on keeping the same slower exploratory pace you have been doing and end the series at one of the main cliffhangers to drive people to your LN?

Like this series strong point is it's incredibly good character writing. These people feel like fleshed out avatar with their own ideas, goals, hopes, dreams, and then back half of the series just seems like it throws that aside for hype moments and aura farming. I get why, you want to showcase more plot elements to draw people into your LN, but instead this just us think the LN has these same pacing problems and opt out of it.

And because of that I can't recommend it as anything more than a palette cleanser between larger series or if you're deep into the isekai rabbit hole like I am and just reading any isekai you can get your hands on.
