I enjoyed this series show much that I binged watched it, there's so much to appreciate in this anime. I like the story, the war scenes, also Characters.

As the name suggests if a mature civil servant got summoned to another world that was on the brink of war, how would they conduct themselves as the summoned hero?

You guess its as realist as they come right, so that's exactly it in this anime.

I love how economy restrains are addressed in this series and how the character tackles challenges as they come along.

Having said all of this you would need 100+ episodes to show the full depth of the world building, its amazing how the producers managed to condense information so much with an awe entertaining series. Well Done Team!

Hope to see more of this show soon :)
