Fun Fic Ideas!

Inspired by a few post, most recently a School District AU Zald and Alfia. I basically want to see any interesting ideas. Especially those that aren't technically the "generics" like Bell being in another family and being stronger. Or op OC that probably an isekai protag now in world of Danmachi and ect.

You know one that kinda popped in my head, probably like actually showing the deities not so clueless of "modern technology" or other things like anime, which I seen a couple times in "isekai fics" even though it more like the opposite. And probably decided to change the "genre of their game" and turn it from "medieval" into "sci-fi". Like introducing crystal television, inspired by one of the chibi spin off mangas where Loki Family tried to watch Sword Oratoria anime on their t.v. which then broke and burst into Hestia Family home to watch on theirs.

But anyway any other "fun" ideas? Even if it's still similar to the "generics" I'm still interested to hear, or I guess read. Whether they already exist or just an idea you have.
