I’m on the 7th and most recent.

The thru line meanders a bit, but not too bad. I wish I had read them chronological instead of in order (5 and 6 are swapped, and 6 is a bit different tone)

I think of them as popcorn books. Very light, quick reads. I actually read the first two on a flight back from Europe. Definitely fun, somewhat predictable/formulaic but it doesn’t take anything away for me.

It’s because they used the prequel bullshit by Kevin J. Anderson as a basis. He is a shit writer.

I would much rather see a God Emperor series. There is so much you could do with that.

Another Jpop/metal band is Necronomidol. Whereas babymetal is jpop with metal, I think they are more metal with jpop.
