Hmm, I kinda don't get the 2 categories in this one. This is my understanding of those two:

• A) Narnia - a Christian/Religious/Capitalist allegory reinforcing their ideology
• B) Connecticut Yankee - a satire or deconstruction of the original setting that point out flaws of ideologies

If that's the case, why is I'm in love with the Villainess Yankee? and why is Magical Revolution Narnia?

Is that all? Am I missing something? if there are only those two categories, what about stories like Isekai with Smartphone, Solo Leveling, etc. where the main goal is just for wish fulfillment?

However, the origin of both isekai tendencies is The Divine Comedy, where the social satire/reform and religious ideology exist in harmony. Ironic that it could critique the schism but became a schism itself.

I must not have picked up on the Christian themes in Ascendance of a Bookworm
