First impression
It has quite a few of religious words/terms which aren't commonly used in day to day speak, that someone around N3~ wouldn't know of. That being said, it's not overly excessive and a lot of those words get repeated throughout the volume.
The grammar is fairly simple though, I'd say a bit easier than something like Chainsaw man in some parts. I haven't read too many manga in Japanese yet so I can't give a more detailed comparison than that. However if you're comfortable with N3 manga then the dialogue in this will be comparable to that.
As for the story, the plot is quite simple but yet fun. After the first chapter it primarily focuses itself on action, but I'm sure that the story will develop on its premise further across later volumes. The pacing is quite fast though, so for someone who is still not the fastest at reading that can be quite nice. The art is decent/okay at most parts, but at some fight scenes they can get quite good and nice to look at. If you're into battle shounen then this might be something for you.
Because almost all of the unknown words you encounter will be niche words relating to religious-like things, I don't really see it as good material for furthering one's vocabulary. That being said, because of its fast pacing and action oriented setting, it is really easy to get through. Which is in my opinion way more important. I'll likely edit this review once I've read the rest of the volumes.
