The character writing, while not anything breathtaking, was definitely what sold the entire show. There's a nuanced undertone to each of the conversations between the characters; a sense of gentleness and tacit understanding between them. The relationships between them were warm, supporting, and realistically developed. The dialogue writing is thoughtful and grounded.
I especially loved how they addressed Sei's initial reluctance to come into the role of Saintess. It was a little bit of a shock; I'm so used to watching action-packed isekai shows where the MCs adapt into unbelievably harsh and challenging environments despite being nothing but normal people in a peaceful modern society in their past lives. In this case, seeing the people in Sei's life gently support her no matter what decision she ends up taking (and all this done with very little explicit addressing of the actual topic!) was such a beautiful thing to watch.
A scene I also particularly enjoyed was watching the scene between Aira and an unnamed female student at her school on the rainy day; the time spent on that quiet, wordless exchange between them with Aira finally being left behind and simply using magic to dry herself instead was such a wonderfully written moment. It was such a small scene but the choice to emphasize it added so much colour and depth to her character.
All in all, this was a wonderfully comforting and simple series, with the ending being a beautiful revelation as to why the title of this show came to be in the first place. Execution on all fronts of this storyline was lovely to watch, particularly with this cast of loveable characters.
