Ah, I've always wanted that storybook too! It's interesting how much art is in that and the guide that's not available elsewhere, I really wish I had them. I've used an auction service once and man did it cost too much. One reason why I haven't really looked into it any further recently, another being that anyone with either on Yahoo Japan usually puts them at a high price.
I wouldn't take a single English name they give the characters much credence to be honest
On their official site(which you can still see an archive of) they had a characters section and several of them were nonsense. They list Ibiri as Ibiri there though, not Ibri. That's one thing when it comes to names, they can't keep it consistent when putting it to English heh. Worst example I know is they call Kris "Clis"
Edit: disregard the former wall of text, looking back I wasn't making sense when I wrote it :x
Oh, and if GhaleonQ is looking, I messaged you on Youtube but no response yet. Did you receive it OK?
