>MC is the son of an isekai'd salaryman/civil servant and a lesser noble
>dad killed the demon king in his youth and becomes a big hero, but not big enough to get any meaningful societal change done (monarchies are still a thing, so are slaves etc.)

>killing the demon king caused all of the magic energy in the world to slowly start disappearing
>started slowly at first, but now come around the start of the story healing magic fireball can now only be afforded by the aristocracy
>story starts with dad's funeral, and now various parties start to move now that the "big deterrent" is gone
