Now that I looked closer, Luso is indeed carying a book around (looks like the Grimoire, it's almost certainly the grimoire). But I don't know about Adel. There aren't any screens with her in the 'normal' world up until now, unlike Luso, who we saw in the normal world from the very first scan. From the first character details about these two, it always seemed to me that Adel was from the 'fantasy' world...

BTW, I heard something about judges. I don't have an official source, but anyway, I'll tell you guys.

It appears that you can have a judge in your clan! If you summon the judge, you have to obey his laws. In return, the judge protects your characters from dying permanently after 3 turns (like in FFT). If you don't want to obey laws, that's fine, don't summon the judge. The laws of the judge you summon only apply to you, not your enemies. Your enemies of course, can also summon a judge on their side, but their laws do not apply to your team.

That is what I heard, but I can't confirm it. Still, if it's true, awesome.
