Ah fuck dammit THAT asshole is still running Hell's Project 731-Clip?!? Shit, if Narnia's convinced that the only options are "letting any of Knightroller's ideas come to fruition" and "remove non-Demon", suddenly his position is a lot more reasonable.
If Narnia’s whole goal is basically “get humans(iruma) out of here ASAP before my father can get his hands on them”, then what initially looks like hostility toward humans starts reading more like a ruthless protection strategy.
PS: this just my thought because the way narnia react to the call maybe it a hint or something.
Yeah, he's definitely extreme in his ideology, wanting netherworld to be devoid of anything that isn't a demon and also being big on maintaining the status quo (hence what happened with the many-ears tribe,) but it's definitely possible that it's less that he wishes for extermination of other beings and just has a rather warped sense of what will keep demons safe. Honestly there has been some aspects of Baal's plans (since they seem focused on using Iruma in some way,) that don't feel like they line up quite right with Narnia's goals, though obviously it could just me reading too deeply into things, but Narnia did establish that he and Baal are just using each other to achieve their ideal worlds, implying that they aren't exactly allies, but are willing to work together wherever their interests overlap
Here we go, its the battle now of who can get Iruma first. I think we will see factions of who want to capture him, protect him, or straight up banish him. This is gonna be an all out war lol
