How do you imagine the ships that are now in the au (AinzxAlbedo, EntomaxCocytus, SebasxTsuare, PAxNaberal) babysit their kids?
Great question! I've been meaning go over all the parenting styles each characters have
Ainz x Albedo: They are actually pretty good parents, Albedo settings and personality lend very well to a maternal role, and Ainz is surprisingly good at it to, afterall he has been treating the NPCs has his children for a while lol. However this comes at the cost of them tending to be overly protective over Montaro, if it wasn't for the fact that they both have to be away at work they wouldn't leave Montaro alone.
Cocytus x Entoma: they are an interesting case, during the egg and larval phases of their brood Entoma was a very aggressive mother, never letting anyone get too close to her babies. After they matured Entoma became much less present, Cocytus then took her role and began training his many children, he isn't perfect, often being a bit naive, but he is trying his best to raise worthy descendants.
Sebas x Tuare: there's no other way to describe their parenting if not exceptional, both were very kind and understanding parents who raised an exceptional child. Tuare was scared at first but soon enough she proved to be a very capable mom, Sebas too was worried, though his face did not show it, but it was as if he could feel touch-me's experience to fatherhood. They are both "sickeningly wholesome" as Demiurge once described.
... So far these all I have rough ideas for, still need to work on the other parents.
