"Lad, what do you-" Armodeus started, confused and nearly shocked by the Demon's insinuation.
"You know that I was an artificial creation by the Monster King, right? Well, fact is, I have a soul. Without one, I couldn't exist. But how exactly do I have that soul? It's impossible to create souls out of nothing, and that rule should still apply to the Monster King. If he was powerful enough for that, then this world would already be doomed." Eiro said, and Armodeus slowly nodded his head as he understood the logic behind it.
"So... Yer sayin' that the Monster King took the souls of people to create artificial monsters?"
"Wouldn't it make sense if that's the case?"
