First thought: I was initially kinda annoyed that all the demons getting involved were related to people we already knew. But then I remembered that it kinda makes sense that elite demons are a small-ish social circle. And then I realized, what if it wasn't the mangaka being like 'I want everyone to be related to the characters I already have' but instead an in-story reason?

What if, instead of Ameri's birth involving certain demons because they're the relatives of the Misfit Class, Sullivan put together the Misfit Class because their parents were involved with something to do with Merize or Ameri's birth in the first place? Demons that Sullivan knows either know about humans and don't hate them, or, even if they don't know the human part, demons that were involved in the events in such a way that Sullivan could be like, 'Hey Caim Caiman, remember that time I asked to study your bloodline magic to develop a universal translation spell and gave you that pass to the succubus club? Yeah, that was so I could help Henri-kun confess his love to a human woman. Yes, humans can be romanced!' And nobody in the Caim clan would ever eat someone they could flirt with instead, let's be real.

So first theory: Sullivan made the Misfit Class out of students whose parents would be the least likely to jump straight to 'let's eat the human' if Iruma's secret got revealed while visiting a friend or something, and who Sullivan could almost certainly convince to keep Iruma's secret quiet.

Honestly with the reveal that Amaryllis was probably checking in on Merize during her pregnancy, it wouldn't surprise me if Amaryllis has already clocked Iruma as a human. Like, however it eventually comes up, I imagine her reaction to be like, 'Oh, that darling Iruma-kun? Of course he's human!' Or something.

My much darker second theory: Naberius Knightwalker was a member of the 13 Crowns. He's obviously not by the canon era. He also pretty clearly had some ulterior agenda for Merize and Ameri. Knightwalker is Narnia and Kalego's dad. Canon era, Henri is a 13 Crown, Narnia hates humans, and Henri told Ameri that there's no more beauty in his and Merize's story.
