Do you happen to know if they are using the broadcast or home video version? The US Blu-ray uses broadcast version.
The home video version has a lighting/shadow effect that's missing in broadcast version.There's the NHK logo at the end of episode 20 (in next episode teaser), if that is anything to go by. I don't see any difference in the video embedded with your tweet however.
It's full of artwork and production material. There's little to no text except the description of the main characters (which makes up less than half a page when all are considered together).How's the book like? It is more artworks and illustrations, productions materials etc. or leaning onto interviews et al?
Oh, it's just A5? I somehow thought it might be like Shigurui then, which was A4.I expect the booklet to only contain 25 or so pages of illustrations and the rest being textual content in regard to the series. Still better than the other releases. Hopefully it has all of the JP illustrations, they are absolutely beautiful. But I think this is an A5-sized set, not A4.
Sentai's 2 part release has the two anime-artstyle-key illustrations with the characters as children for p1 and teens for p2. Those two illustrations don't seem to be included in the JP release either. (Would presume it should be added to the guidebook's art section; if Sentai managed to get access Dybex should be able, too.) The backcovers has one of the JP cover arts featured in small next to the summary text and screenshots. (All pretty cramped.)Also, the Sentai/MVM versions had no booklet, I presume the illustrations were on disc?
