There is some, but I don’t think it’s overwhelming, as in, you won’t have to learn a new one every few pages or anything like that.
Also, there’s the protagonist’s monologue as well, which takes care of explaining what is going on pretty well. I don’t always understand it too well, but that’s more because I’m a complete newb in how even basic economics works. For a nerd like you, that should be fine.
I really like it, mainly for the two main characters. They carry the story forward really well and their interactions are often more complex than the economics too, so you can always have some fun trying to figure out what the heck ホロ is thinking
The stories themselves are pretty tight too. There’s good foreshadowing (so nothing comes out of nowhere) and the settings are really well-thought-out, so stuff makes sense. Also, the situations they find themselves in are interesting even if you don’t love economics, like me (I actually kind of hate it, so I didn’t expect to enjoy this series so much).
Also, 狼耳. Great stuff.
Anyway, trying at least the first volume doesn’t hurt too much. I definitely recommend it.
