Yeah, it would actually be nice to see a first progenitor in the manga, light novel, or anime for once if you were one. Thus far, the highest progenitor we've seen thus far was the second progenitor, Saito. We might be able to find a new progenitor in Mikaela's light novel though.

Of course, I would also go for a possession-type demon weapon.
