@Kendama This is a pretty fair assessment of the broader genre, which maybe is why it's popular. The power fantasy
is what people are looking for in a place where they feel powerless. Especially because the power is more often than not, common knowledge. It's putting the reader in a place where they can imagine their knowledge being used. I mean, for an example that's in this manga, we all know about the 2007 financial crash, and presenting that as a problem and then showing a solution can be interesting. Although I totally understand how ultimately, this makes for a story with very low stakes and that can lead to someone not wanting to read it.
I'd be super interested to hear what of the broader genre you do like! I've read
Death is the only ending for the villainess and it's great and I'm always interested to read more.
