IF i say it in a few words: It's anti-climatic.
The longer version would be it's constant hit or miss with this series. I like slice of life series but this one mixes standard heroic tale with slice of life, heroic tale is just in growing stage but i'm pretty sure with all the raised flags we will see it.
MMC personality is just the standard Japanese MC. Weak, agreeable and sudden iq falls (author trying to bend the story).
I rated it down in my personal library was 5 (when i started to read) after 3 years i changed i guess and now it's 3.5.
I guess i looked at the series more sober minded and became older and even more "experienced" in manga, so after re-reading it up to chapter 31 i wasn't feeling any excitement or interest, to be precise it just started to nose dive, coupled with critical flaws that author made in beginning of the story.
