Wow, I'm truly perplexed by the process here, like why would you do this intentionally when you could just have the next page be black or just plain blank with the first glossy cover adjacent, and if you're just dumping the volumes in with the index pages and character bios (which do change to add pertinent information be fair) that's... also weirdly uncontrolled.
I guess what I'm saying is I wouldn't do this unless it was by accident of the covers directly following a story page with no original buffer present (this likely couldn't happen in later volumes), but even if it did turn out that way this is precisely what you exert a little editorial or formatting control over.
Oh well, I don't really care because I wasn't under the impression this were going to be the objectively ideal editions by any means anyway (just best for me because of the size, language and improvements to the original localization), and compared to art, printing, and translation errors this is really a minor thing.
Plus, when they start publishing a faux-Berserk side by side with Miura's work in volume 14 it will be really awkward! Maybe we could write friend-of-the-site and SK.net member Chris Warner to see if they could stick the guidebook back there instead, ala the prototype in volume 14, and start fresh with Perserk in the next deluxe edition.
Unfortunately, I presume their publishing arrangement doesn't simply allow for that, but they could try! Hell, at some point they're going to need to plan how to format the final deluxe edition if the complete volumes aren't divisible by three. Maybe the last couple hundreds pages could just be glossy blanks.
