LOL, I've had the book for a few years and didn't notice it either, until now! It's a heckin' long boy, too. : DThis is charming/endearing to me, I wouldn't've known it had a tassel/bookmark otherwise
I ordered mine from this seller on ebay in 2019. It looks as though the listing is still up, and only a little more expensive (from US $39 when I bought it to $45 now). The shipping might be extra, though. I think you could also find it on sites that sell manga and doujinshi, but I don't know as much about those.By the way, does anyone know where ODM is sold? I want a little bit, well just a little bit cause I know it's expensive
About the ODM, well... I've scanned it all!
And I'm also planning to translate the missing pages from the old forums... when I'm done with Xenoblade 3 (and at this rate... never ) I'm going to do it.
