Lilium becoming something like a private party of adventurers working directly under the Imperial family is way better than just Laplace getting hired to replace Maxwell.
All the Arienora clones surviving was a pleasant surprise. Gave me some Railgun Sisters Arc aftermath vibes, and the clone girls sporting different hairstyles was so cute.

Nouhin empire will become famous as the empire that has over 10 princesses!
Something like that would normally be a succession nightmare, but since all the girls love and respect the presumptive heir Arienora onee-sama, this shouldn't be a problem.
What's the deal with that crazy-eyed guard? I don't even remember if her sexist childhood acquaintance Ryan was killed at the end of his comeuppance, but if he survived maybe it's him.
