I often notice that Nazuna has one of the most intricate character designs especially even among Light's minions specifically her armor - it is so intricate that the artist likes to draw her as super-deformed and we often see her being in very goofy situations so she can be drawn easily
This is true, but I want to point into the art style in general in this manga. I honestly love it.
The artist managed to have a very good balance of all the type of designs (at least so far).
None of the intricate designs feels overcharged.
None of the simple designs feels uninteresting.
The discret designs blend themselves perfectly in the story and the loud ones grab the attention without bothering it.
I'm not here to say that it's the pinacle of art and originality, but this manga is definitely one of those hidden gems that where, if there's one thing you can't complain about, it's the art style.
