If demons aren't supposed to have holy resistance, and fallen angels are a thing, who's to say 'risen demons' wouldn't be possible? Because Eiro has holy resistance, if he manages to level it high enough, 'risen demon' or maybe 'holy demon', could be a unique evolution for him? Like his final evolution maybe? Also, side note, If the collector isn't called Moriarty, or Raz al ghoul for the pun, I'd be upset at the missed opportunity
