Seems like elf MCs have been on the rise in anime. There's a new anime where the main character is an elf reporter. I do dig the blend of a late 1930's world with medieval fantasy.

>world with blended 1930s/medieval fantasy aesthetic
>similar treatment of culture being prewar/fantasy
>have electricity, radios, bombs, and artillery
>but the tanks are giant bird centipede things with armor and guns strapped to them
>the bombs are dropped from dragon-stingray looking things
>still use swords and armor because magic + adventures being superhumans prevented small arms from taking off
What do you think about schizo tech and schizo culture in your isekai?
