"Huh?"
'Huh?'
Both Bruno and the demon prince uttered the same word at the same time. Each of them had different questions behind such confusion of theirs however, since one was a spectator, and the other a participator.
Bruno uttered his confusion, because he did not expect God to be recruiting the bad guy. The demon prince however, he uttered his confusion, because he did not expect God to be recruiting him. It's basically the same, but completely different at the same time. One was surprised, while the other genuinely did not understand. As for the reason for the lack of understanding, that's because it doesn't make sense for a real God to do recruiting.
'Unless he has certain intentions…' The demon prince could only assume such, because anything other than the God wanting to use him for some purpose, did not make any sense to him.
