After much delay...
Scanning book II was an absurd pain for some reason. It may as well have been cursed. In the end though, all of the actual details are aligned properly, and that's all I can ask for... there's a few times where you can see a bit of bleed through, but with how hard the lines are on some of the sketches vs ones on literally the other side of the page, I did what I could.
With that, that's the last of the booklets done though! I'd like to revisit the box set once I have some better tools, because the actual blu ray case covers go so unfathomably crazy it's insane, but they also have some glue residue on them in a couple places that really scuffs up the scans, so. At some point.
In the meantime, though, I'm onto other things... because I have so much Post-Eureka Seven content in physical form that noone's ever scanned. It's a problem.
