is it wrong that I'm enjoying this more than the main series?
nah I think enjoy this quite a bit too, especially because Iruma has alot more control as mob boss over the political landscape.
In the main series, as a child without any responsibility, he doesn't really have that. Events happen around him (not that he doesn't have any agency or that his actions lack weight in term of narrative consequence)
Not that, that is bad writing (the opposite actually!)
But I can see why one would prefer this one though.
I do think that a large part of the enjoyment comes from the fact that this is an au.
Azz's entrance for example would not have that kind of hype without us knowing who he is.
